I am running an Algo on EC2 instance machine and its working fine in the morning but as time passes by there is a lag of 10-20sec in order placement. I am unable to identify the issue. The python file is of only 14KB Kindly guide where is the problem and how to rectify it.

I'm trying to make a custom Ubuntu 20.04 image from a .iso file that I have uploaded to Amazon S3. I've went through all the steps to create an image pipeline, but when I get to the end and hit create pipeline it just says `Error message: InvalidParameter: The service role role-name provided does not exist or does not have sufficient permissions`. I've made a role specifically for this pipeline, and even when I attach a policy that has all permissions to all resources I still get this error that says it doesn't have permission. Any help here?

Hi Gurus, I am working on setting up VMC on AWS. Can anybody please advise with Bill of materials(minimum required template) for setting up VMC on AWS? Thanks Jo

According to announcement "The AWS Lambda console now supports bulk update of layers", I was under the impression that "This release (would) eliminate(s) the need to update one function at a time or utilize an external script to perform the update on multiple functions." I am currently using an external script to update multiple functions when lambda layers are updated. Is this notice implying an automatic way to update the layers? If so, how and where would I access this feature? I am familiar with accessing the AWS Lambda console and manually bulk updating all functions that use that particular layer. Any clarification would be appreciated! Thanks again! Click [here](https://aws.amazon.com/about-aws/whats-new/2022/03/aws-lambda-console-bulk-update-layers/) for site.

Hi I am migrating from Windows to Ubuntu a website and hence created a Ubuntu instance. The instance works for some hours and suddenly one cannot SSH into the instance. The Instance reachability most time shows instance not reachable. Rebooting a couple of times gets the instance running. Any solution to get a dependable instance running ? Did not have this problem in Windows Instances.

Hello, I have an instance need to auto scale only volume not instance type. Is it possible to auto scale only volume of instance?

When using AWS Batch is there a way to limit the maximum number of EC2 instances that AWS Batch will have running at one time? Ideally, this would apply across all compute instances. Does AWS Batch enable this or are there other AWS services that can be combined with AWS Batch to allow us to achieve instance based limits? An example would be say I am running AWS Batch for some workload. But I want AWS Batch to at most have 10 EC2 instances running. Is there somewhere that I can configure AWS Batch such that it will respect that limit on EC2 instances?

are there any ways to use hyper -v without using a bare-metal dedicated server ? Regards

So, does anyone know what the upgrade path is for the Control Tower Python 3.6 lambdas? Did AWS publish any way to resolve these issues before CT breaks in a couple months?

I have hosted my Ec2 instance in Mumbai Region, Which goes down every day for few hours. Giving Host Error 524. (Billing section is working fine)

Hello, I created my OVA file for my VM via VirtualBox and loaded it to S3. After importing it to Image Builder to create an AMI, I get the 'ClientError: Unsupported kernel version 5.10.0-10-amd64' error after some time during the import, the operation aborts. I selected the Amazon Linux 2 OS and I was under the impression that this OS was upgraded to 5.10 back in November 2021 per this post: https://aws.amazon.com/about-aws/whats-new/2021/11/amazon-linux-2-ami-kernel-5-10/ Can someone point out how this issue can be resolved? Or is there no solution at the moment to resolve this issue. Thanks for any feedback and let me know if you need any further information.

Hi, I'm making some experiments regarding the impact of JAR size on Lambda Cold Starts and response times. I have created 3 JARs of different sizes. | JAR Size | Response time| | --- | --- | | 10mb| 1s| | 64mb| 6s| | 100mb| 12s| In Cludwatch logs I can see that init durations for all these Lambas is on average ~620ms, but for every lambda the response time is different and I don't know why. The code is the same(there is no logic -> all of them are returning a String), differences in size are due to different maven dependencies that I added. All of them are from AWS SDK. Is this normal?

My EC2 is not reachable anymore. The status checks return - "Instance reachability check failed". I am running a t3.micro Ubunto instance.

In the EC2 instance details, i am finding this error "User is not authorized to perform: compute-optimizer:GetEnrollmentStatus on resource: * with an explicit deny in a service control policy" under Amazon Compute Optimizer section. Because of this while I am connecting to EC2, it is showing error as "verify that your iam policy is correctly configured to use ec2 instance connect."

Dear community, **Background:** We are working on a project where we have to transfer .db files from one ec2 instance to another more frequently. Both the instances are r5.2xlarge. The .db file is around 100 GB in size. We are using the Bastion host to access the actual EC2 instances. We are trying to copy a file from the bastion host because the actual EC2 instances cannot connect to each other. **Issue:** When we try to copy the file using scp command, the first 16GB is normally fast, but it slows down very much after that, taking a huge amount of time to complete the transfer. We have tried many times and this issue is reproducible. ***Command: ***scp -3 ec2-user@ xx.x.xx.xxx:source file address ec2-user@xx.x.xx.xxx:destination file address The scp -3 used in the command is to avoid the actual files copying via Bastion host. **Expectation:** Can you please provide us some suggestions or recommendations to improve the copying speed across these instances? Thanks in advance.

I am getting this error but I am not able to SSH into the instance. I have already restarted it but still can't ssh into the instance. What should I do? The steps to replicate this are: 1) We create an AMI 2) We create an instance based on that AMI 3) We get reachability failed, status impaired error 4) System log says: Failed to start LSB: Bring up/down networking and Started Crash recovery kernel arming . Thanks in advance

Hello all, I am wondering how I can list all VM types/flavors available for use as workspaces/VDI? Thanks. Boris.

When I ssh into Kali image ec2 instance from my windows 10 Lenovo Thinkpad, no wifi adapter is shown for intel dualband wireless ac 8260 which is in the motherboard, not external USB wifi adapter. I'm a beginner please help. Is it not possible to put my wifi in monitor mode using ec2 instance??

Our EC2 instance (US-West-2) became unresponsive, web traffic failed to connect, and I could not SSH into the server. After shutting down and then launching the instance again activity and access have returned to normal, but I would like to know the cause so this doesn't happen again in the future. I have checked the syslog files but there was nothing obvious logged that would have caused the issue Any advice would be much appreciated The instance_id: i-0d2dc06a6d078f519 The instance type is: c5a.2xlarge

I've seen some aws blog posts about cutting node module bundles by 50%+ moving to version 3 and then further cuts with optimizations. Is the cpu/clock time savings linear? How about memory? I am not familiar with more bare metal concepts. TIA.

I need to create a desktop session (using commandline only) from an AL2 linux server to a windows machine. I am trying to use xfreerdp and rdesktop. I have installed them on my AL2 server. I have installed X11. When I run any desktop client (rdesktop) i get this error : ``` rdesktop IP_WINDOWS_MACHINE Autoselected keyboard map en-us No protocol specified ERROR: Failed to open display: :0.0 ``` I have tried setting up the the DESKTOP environment variable to `:0`, `:0.0`, `localhost:0`, `localhost:0.0` but nothing seems to work. Is there something I am missing in the setup? Is there a better way to do it? I have also tried `xhost +` which doesn't seem to work with the same error message.

I have an instance that is stuck in the stopping state more than 10 minutes. Instance ID: i-0e23c7d8101068aec. Already do Force stop but not successful.

I have an ec2 instance of type t2.micro and I have a web service that communicates with services outside the server so it needs internet and I have noticed that internet connectivity is lost at least 1 time a month and I have to restart so that back to normal and I would like to solve that problem. It is worth mentioning that I have a load balancer for that server and a security certificate for my domain.

I am having an issue with my Lightsail instance becoming inaccessible. Around 0300 UTC the CPU will spike to 100% usage(for less than 5 minutes), then I begin to get Instance Status Check Failures. I cannot log in to the Wordpress admin dashboard, nor can I access SSH via Putty nor the web console. I have to manually go in to Lightsail and stop the Instance and then start it. I am intending this to become a production server for the website of an event I run. Very simple Wordpress site which should run with no issues on a 1GB, 1vCPU instance. It is currently just in development so there is literally zero traffic to the site so there is no way it should be using any resources really... Looking through the syslog I can see the following around the time the of the CPU spike ```Mar 20 02:08:03 ip-172-26-4-68 systemd-networkd[445]: message repeated 10 times: [ eth0: DHCPv6 address 2600:1f16:237:5d00:7ba1:b960:d9e5:f2e9/128 timeout preferred 140 valid 450] Mar 20 02:09:01 ip-172-26-4-68 CRON[18990]: (root) CMD ( [ -x /usr/lib/php/sessionclean ] && if [ ! -d /run/systemd/system ]; then /usr/lib/php/sessionclean; fi) Mar 20 02:09:02 ip-172-26-4-68 systemd[1]: Starting Clean php session files...

Can anyone help me figure out how to stop this? Thanks

I'm trying to set up file share gateway and so my first step is to create and activate a gateway. When I give ip address it keeps giving error "this site cannot be reached" <ip-address> refused to connect. I've tried using EC2 instance as well as a vm and and both give the same error. What can I do to fix this?

If we enable the managed updates feature in elastic beanstalk environment, will it install the windows security updates released by Microsoft on the Windows EC2 instances?

Hi, I'm hosting my WordPress website using the EC2 Instance right now. Something went wrong on my website yesterday and I'm not able to fix it. Unfortunately, I haven't made any backups as well. So, I just wanted to ask if there's a way to date the instance back to a past date like maybe March 7th or 6th? Any help would be appreciated. Thank you!

I am curious what will happen to ec2 classic resources after the August 15th deadline. The ["How to Prepare"](https://aws.amazon.com/blogs/aws/ec2-classic-is-retiring-heres-how-to-prepare/) doc just mentions >On August 15, 2022 we expect all migrations to be complete, with no remaining EC2-Classic resources present in any AWS account. What will happen to resources that are remain in the AWS account? Will the resources be available for migration or backup after this deadline or will all resources and their data be lost?

My instance (i-0addfa8225c243241) rebooted automatically yesterday. It stopped automatically today, I cannot connect to it. So I had to reboot it via console.

Hi all, I have created a Windows10 Custom AMI to run high-end graphic gaming and Content Creation purposes to use g4 instances on EC2. I want to know if this will work without any problem as I have not tested it yet, although I have installed Nvidia Graphic drivers on it.. It seems to be running fine but I just wanted some expert advice. Please share some AWS documentation to support your thought. Regards Gopal Thakur

Hello, By using [https://documentation.suse.com/suse-distribution-migration-system/15/single-html/distribution-migration-system/index.html#_run_the_migration](), I have migrated EC2 Instance which is running on SLES12 SP3 --> SLES12 SP4 --> SLES12 SP5 to SLES15 SP1. Now we would like to migrate from SLES15 SP1 to SLES15 SP2 and then to SLES15 SP3. To do so when we fire command "zypper migration", below mentioned error is occurring: ``` Can't get available migrations from server: SUSE::Connect::ApiError: The requested products 'HPC Module 12 x86_64' are not activated on the system. '/usr/lib/zypper/commands/zypper-migration' exited with status 1' ``` All repositories are of SLES15 SP1 in the output of "zypper repos". However SUSE Registration status shows, the product 'HPC Module 12 x86_64' as not registered. Please guide me to fix the issue and migrate from SLES15 SP1 to SLES15 SP2.

Hi! I have an issue with a migrate instance from Azure to AWS. I do install the Kernel version for AWS in the instance (Ubuntu 18.04) and enabled the ENA support for that.

Does Databricks give customers the option to choose reserved instances or are there any barriers to savings plan ? Does EMR provide reserved instances?

Under the limitations page for hibernation within EC2 [[1]]( https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-hibernate-limitations.html), it is mentioned that: "If you create a snapshot or AMI from an instance that is hibernated or has hibernation enabled, you might not be able to connect to the instance.". Could anyone clarify the meaning of this statement. Does it mean: - You might not be able to connect to the instance whilst the snapshot or AMI creation is in progress - You might not be able to connect to the instance after restoring the snapshot or launching a new instance from the AMI - Something else 1. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-hibernate-limitations.html

I have a table `MyTable` with `count` (numeric) among its fields. I want my `CountListener` function to be triggered each time the value of `count` gets updated, for any item in the table. I've enabled the stream (New and old images) for the table and now I need to write a filter for the stream events in order to invoke `CountListener` all and only each time `count` changes. From [the docs](https://docs.aws.amazon.com/lambda/latest/dg/invocation-eventfiltering.html) I see how to write a filter that compares the value of a field with a constant value: I wonder if I can compare the value of `count` in `NewImage` against the one in `OldImage` and trigger the lambda if and only if they're different.

Hi, I have an EC2 instance which seems to have crashed recently. When trying to restart, it fails the Instance Status Health Check and we cannot connect to correct the issue. A new public IP address has been assigned but there's nothing changed in the firewall rules. We've also followed the troubleshooting guide and downloaded the system log, but nothing unusual there. Any help would be appreciated.

Besides using the SMBLibrary, is there any way to access a windows FSx filesystem from a lambda function written in C#? Is there a way to mount the FSx filesystem in the lambda so it can be used?

Hello , We patch our systems monthly but we needed a patch status report once every patch cycle is completed .Suppose we have around 100 servers out of which 90 got patched and 10 got failed .If an automated report can give the patching status then it is going to be so easy to fins those machines where not patched . Thanks Sujith

Hello, My Aws Lightsail instance is keep crashing and freezing almost 10-12 times a day. I am losing my website ranking and visitors because of this. Can anyone help to fix this?

I am using the free tier account from India. I want to subscribe to Amazon FPGA AMI, however the subscription fails, stating "You must first review and accept terms." How much i click / download / review the terms , the subscription does not work. Is this due to some step i am missing for its not enabled for india ?

My services are running on Beanstalk, using T4g instances. By default, the unlimited CPU credit mode seems to be enabled. I'm pretty happy with the auto-scaling setup, and I'd rather have more instances boot up than have unpredictable costs related to the unlimited CPU credits. Is there a way to disable the unlimited CPU credits mode? Disabling it per EC2 instance is probably not an option, as I'm guessing the auto-scaling group would just re-create it with the unlimited mode enabled. Did anybody do something similar? Thanks!

This is a little embarrassing but I created an ec2 instance some time ago and don't know the account or email associated with the instance. I have the pubic instance IP but cannot connect to the instance because I forgot the password. The instance is active and running as RDP responds. Thanks

According to the [blog post](https://aws.amazon.com/blogs/networking-and-content-delivery/application-load-balancer-type-target-group-for-network-load-balancer/), you will be able to configure single ALB as a target in NLB. So what will be the required design if the target ALB has port redirection scenario like 80 to 443?

For one of my environments, I receive the following error: A problem occurred while loading your page: Configuration validation exception: Invalid option specification (Namespace: 'aws:autoscaling:launchconfiguration', OptionName: 'InstanceType'): Your selected instance types (t1.micro) aren't available in your selected VPC Subnets. t1.micro is available in [us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1f]. Please check your VPC Subnets. Does anyone know how I can change the subnet when I can't access the page to do so?

I was creating some Ubuntu machines in EC2 and saw that some Ubuntu versions have AWS NTP Server set for Network Time Protocol (NTP): Machine 1: ``` ubuntu@machine1:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.3 LTS Release: 20.04 Codename: focal ubuntu@machine1:~$ systemctl status systemd-timesyncd ● systemd-timesyncd.service - Network Time Synchronization [...] Status: "Initial synchronization to time server 169.254.169.123:123 (169.254.169.123)." ``` Machine 2: ``` ubuntu@machine2:~$ lsb_release -a No LSB modules are available.

Hello, I've been using EC2, FPGAs for about a 15 months now. I've always been using f1.2xlarge instances, with Ubuntu OS installed, and it worked as expected. Now, due to the amount of CPU intensive work I need to do, I've decided to try using a more robust f1.16xlarge. However, I ran into problems here. I've done all the steps: Loaded the AGFI, checked via `lspci` is it available, and then tried some simple XDMA read/write tests, just to make sure the connection is still there. Sadly, I get no communication with the PCIe FPGA board. Below is the dmesg output, that reports that the "magic" error in the descriptor happened. Again, I'm using the same driver, same AGFI, and the same Python wrappers around C invocation of kernel. ``` [ 1683.589120] xdma:engine_service_final_transfer: engine 0-H2C0-MM, status error 0x80010. [ 1683.589123] xdma:engine_status_dump: SG engine 0-H2C0-MM status: 0x00080010: MAGIC_STOPPED,DESC_ERR:UNSUPP_REQ [ 1683.589126] 0-H2C0-MM, s 0x80010, aborted xfer 0x00000000e19d64e9, cmpl 0/1 [ 1683.589136] xdma:xdma_xfer_submit: xfer 0x00000000e19d64e9,1024, failed, ep 0x0. ``` EDIT: I've figured out the problem, after looking more closely at the `dmesg` output, I figured out that the AGFI was loaded on a different FPGA slot. I've loaded the AGFI as I always do: `sudo fpga-load-local-image -S 0 -I $MY_AGFI_ID -H`. I don't see how it could end up on Slot 8? When I try to adjust my test and run it on Slot #8, all works as expected! To be honest `dmesg` shows this pretty straightforward: ``` [ 183.021774] xdma:remove_one: pdev 0x00000000999de0ae, xdev 0x0000000076ff6236, 0x00000000ca7f10f1.

My Linux instance has failed its instance check after upgrade and reboot and I cannot connect to it. i-0436f85533745cd8b showing status check 1/2 hence we are unable to access this instance. i tried rebooting, stop -> start, relaunch nothing is helping me out.. Tanks in advance.

I started a G5.xlarge and a 2xlarge instance on ec2. However, when I tried to check on the GPU status via the `nvidia-smi` command, it errored with: `NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.` Why is this happening? G4 instances worked fine though. Seems to be just g5?

I've installed the gpu driver, mate desktop and nice-dcv following the official guide: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-amd-driver.html Everything works fine for g4ad.xlarge ... g4ad.8xlarge. But when I change instance type to g4ad.16xlarge, Xorg won't start. My first guess was that it's related to multiple GPUs, but 8xlarge already has 2 of them and it works just fine.

My design is consumes ~55% LUTs. The RAM and DSP utilization is pretty low < 10%. When I try add more logic it runs into congestion issues. So, I am trying to reduce some bus widths. However, I would like to know if there is a good rule of thumb on what LUT utilization can be target without hitting congestion issues. I am hoping you guys have such data from various customer datapoints. Thanks

Hello, I'm facing a problem regarding the "1/2 Checks passed" problem, when this problem happens I can't connect over ssh anymore. What could be causing this problem? [https://ibb.co/DtLStm0]()

Hello,my name is Justin and I own a smaller company in Virginia, and thank you in advance for your help and guidance. I started working on a new domain/website several weeks back after getting the technical end set up first and surprisingly I've had no issues until now. My set up is Google domain to AWS (basic plan/$3.99/month), using Lightsail and WordPress. I followed the set up for my instance from an AWS certified specialist on YouTube. That said, I have not set up anything for storage/containers/etc tho I do have my static page set up for my landing page. So, Sunday night I finished working on the site on wordpress with no issues outside of a jetpack warning that had been up for 2 days. It stated that my domain name and IP address were both fighting for the same spot and I needed to select one or it would go into safe mode. Outside of this, my primary updates outside of verbage was in installed a few plug ins. The last one was PayPal which was around $60 for the year. I went thru the process of setting all the pages up and everything worked great. The following morning I had planned on fixing the jetpack issue but once I logged on, or attempted to, I realized that the website was down. All pages refused to load and a few times I got a 504 gateway timeout error message. I attempted to log in thru WordPress but I had the same issue, no loading. I then attempted to relaunch the instance via AWS; however, the instance wouldnt connect correctly to Bitnami. Basically, the black terminal screen comes up but is empty. I then created a second instance (can only have 2 max) and attempted to connect to Bitnami again. This time, it was a success. Circle back to verify and my instance 1 still has the same results of not completely connecting to Bitnami. I'm new, and have a basic account,meaning no technical support. Any help would be GREATLY appreciated!! Sincerely, Justin

Hello We have a problem with the App runner service. Sometime after deployment, we get: ``` 19:32:05 0|kultr | SequelizeConnectionError: getaddrinfo EAI_AGAIN xxxxxxxxxx.xxxxxxx.us-east-2.rds.amazonaws.com 19:34:17 1|kultr | Error: getaddrinfo EAI_AGAIN logs.us-east-2.amazonaws.com ``` After a couple of redeploying this problem is gone. Following https://github.com/nodejs/docker-node/issues/1030 node:12.13.0-alpine was changed to node:12.13.0-stretch but the problem still exists. Something similar was mentioned on this topic https://forums.aws.amazon.com/thread.jspa?threadID=346652&tstart=0 Could somebody advise how we could fix this error and make the service more stable? Thank you!

Happy New Year! I've two ubuntu servers, one 16.04 and the other 20.04 running dedicated Unifi controller software. Both are on different versions of Unifi and both have been solid since build in 2020. Last couple days both have had limited web access to the Unifi gui and ssh connection is there but slow. Top shows 30% cpu usage, 90% memory and 40% swap, pretty normal. I can't find any smoking gun on the server side and it would seem its a aws issue beings they both crapped out at the same time. I have tried to connect from several different pcs and isp to make sure its not on my connection. Any tips on where to start looking?

I've been working my way through a Vitis FPGA 'hello_world' tutorial here: * https://github.com/aws/aws-fpga/blob/master/Vitis/README.md I've gotten up to step 3, and attempted to run the program with: ``` ./hello_world ./vadd.awsxclbin ``` ...but this resulted in the following error: ``` terminate called after throwing an instance of 'xrt_xocl::error' what(): No devices found Aborted ``` Any ideas why I'm getting this? I'm using an `f1.2xlarge` instance running in `ap-southeast-2b` availability zone. One observation I had was that sometimes when I run `ls -lh /dev/xfpga`, I can see the device there. But on other occasions, this results in the following error: ``` ls: cannot access /dev/xfpga: No such file or directory ``` I wonder if my issue relates to that? I did have a read of a suggested prior post: * https://repost.aws/questions/QUPevEIRVGSP6MiHeQ_1Db0A/runtime-error-on-f-1-instance-xrt-error-no-devices-found I think one suggestion there was to try running as the root-user, gave that a try, didn't help for me, same error.

I find if I run these command multiple times, they randomly crash with and sometimes it prints "Segmentation fault" which looks to likely to be a memory access/management issue :( Something else worth saying is this issue only presents itself on Ubuntu distros. I ran out of options to try and reinstalled other OS like ArchLinux and did not experience the same problem. Unfortunately some of the other software I use isn not well supported under ArchLinux and I have to come back to Ubuntu :(

I have a migration job for a Windows machine that's failing to launch the test/cutover instance using the Application Migration Service and is spitting this out: **Error: An error occurred (InvalidParameter) when calling the RunInstances operation: The AssociatePublicIpAddress parameter is only supported for VPC launches.** The destination subnet is a public one and is configured to assign public IPs on launch; manually launching an instance in the subnet does get assign an ephemeral public IP.

Hello, As we have been working on Amazon Linux 2 for a couple of years now, we have noticed that it's sometimes slow when it comes to releasing new version updates on packages. For example currently the latest Apache version is 2.4.52 (there has been 2 security vulnerabilities fixed CVE-2021-44224 and CVE-2021-44790) and yet the latest available version is 2.4.51. Therefore I wanted to ask: 1. Is there any estimate on when the latest Apache version will be available for installation on Amazon Linux 2 default repo? 2. How can we install the latest Apache version on Amazon Linux 2, so that we don't have to wait for the Amazon Linux 2 team to make the latest version available? Obviously we don't want to install it from source, as we want to still manage it using yum package manager. Thanks in advance for your help!

Hello, Do we have any estimate on when PHP 8.1 will be added to amazon-linux-extras on Amazon Linux 2? Thanks!

In the past weeks we have switch a number of instances over to the new r6i instance types. We have used r6i.xl, r6i.2xlarge and r6i.4xlarge instances. These instance types seems to be prone to hangs on the ena driver. Network load on the instances ranges from low to high so the actual amount of network seems to be unrelated to the issue. The instance doen't seem to recover from this on: All these instances have similar message in the logs: ```Dec 27 01:38:20 bc-prod-053 kernel: ena 0000:00:05.0 eth0: Found a Tx that wasn't completed on time, qid 0, index 639. 5404000 usecs have passed since last napi execution.

Using a bastion server can solve many problems but the medium you take to connect to your bastion can introduce some problem. One such problem that I encountered is when I was on my bastion server and created ".pem" file to connect to my private EC2 using EC2 Instance Connect. On SSHing, it asked me to enter passphrase. Which I was never asked on any ssh client. So I tried to use other SSH client (CloudShell in my case) to login to the bastion server. On the bastion, I created ".pem" file to connect to my private EC2. Guess what? I was not asked to enter PassPhrase this time. So I compared both the ".pem" files to check what could be the issue, but still I cannot figure out what the issue is. I request my fellow community to shed some light to the problem. I am attaching details on both the files below - -r-------- 1 root root 1699 Dec 26 19:12 MyKey.pem [on EC2 Instance Connect] -r-------- 1 root root 1675 Dec 26 19:15 MyKey.pem [on SSH Client - CloudShell]

Hello, I'd like to know if it's possible to PCI passthrough my G4dn non metal's GPU through vfio-pci driver or if it's something only possible when using a metal EC2 instance type. Thanks in advance. Regards, Tarik

Hello, I was wondering if anyone has any information about the EC2 c7g preview as it has been 3 weeks since the registration opened (or maybe I'm just being a little too impatient). Thanks.

Hi there, I'm an AWS Lightsail containers user. Except for a few rough edges, I generally like working with AWS Lightsail. One thing that's unclear is what's coming to AWS Lightsail. Updates to AWS Lightsail are very rare so I'm wondering is this service stagnating or is it thriving and worth investing more time and energy? Any information about the future of this service such as what new changes might be coming is very appreciated.

I created a new EC2 instance from : Amazon Linux 2 AMI (HVM) - Kernel 5.10, SSD Volume Type - ami-0bae7412735610274 (64-bit x86) / ami-0bfc5012753c8c986 (64-bit Arm) I assigned to it the right SSM role, but I can't connect to it via SSM : > We weren't able to connect to your instance. Common reasons for this include: ... Amazon Linux 2 AMI (HVM) - Kernel 5.10 doesn't come with SSM agent installed?

I just starting using SMS to manage Windows 2019 Server EC2 instance patching (security updates). I noticed that by default, AWS prevents Windows OS to automatically run Windows Update. I followed the instructions for SMS Quick Setup and the Patching of my servers are failing with the following error message: (I have been searching ALL day for a resolution to this. Modifying registry settings, running DSIM commands, etc. Nothing helps. Seems like some type of certificate issue but I can't resolve it).

I am not very fluent in using Linux at the command line. With that in mind, I set up Plesk on my Lightsail instance, and it is working great. What I am trying to do is migrate some websites from a colleague's AWS Lightsail instance which is also running Plesk. I have used this migration tool before, and it works very well once you get the servers authenticated and a connection established. Unfortunately, to do this, I have the option of providing the root user and password for the source server, or I can use SSH keys as credentials. We tried a few different combinations of credentials he uses to sign in to his AWS account, and to sign in to his Plesk dashboard, but nothing will work. I do not have enough familiarity with SSH keys to make a very educated guess on how to proceed, so I am hoping to simply figure out how to get or change the password for his root user. I do not think this is the same as the "root" user credentials I use to sign in to my AWS console. Why does this seem so complicated? When I have had a VPS with other providers in the past, I could usually get a root user password and this migration tool just works. I know this will require him (my colleague) to connect to his server, which I do not have credentials for at this point. He is willing to give me control for the period required to complete the migration, then he will change passwords again. What I am hoping for is a simple method for changing the root user password, and whether this would cause any issues by changing it, as long as he has it. Would this cause any issues between the VPS and the AWS console as far as administration goes? Any help or suggestions would be greatly appreciated. I have been working on this for over a week with no real progress. I am running out of time.

I'm trying to import a vps from Hetzner to AWS, I created an OVA file using VMWARE converter and generated OVA file using VMWARE ovf tool, at on-premise environment the VM boots without any problem, but when I'm trying to import to AWS using aws ec2 import-image it seeams to get stucked updating at 27" The VM it's a debian 8, how can get more log to see in depth which is the problem. Many thanks for your help Best regards

npm hangs for minutes and then time outs when running in us-west-2. Happens on Windows or Linux VMs. npm on same VM images in us-west-1 and us-east-1 works just fine. Running any of these times out: curl --connect-timeout 15 https://registry.npmjs.org/ curl --connect-timeout 15 http://registry.npmjs.org/ Wireshark just shows that no packets are ever received. What's weird is that when I run `traceroute` from us-west-1, there's only a dozen of hops to `registry.npmjs.org` and everything works fine, but `traceroute` from us-west-2 goes through as many as 27 hops before it times out. Here's last few hops, skipping timed out ones: traceroute -q 1 -F registry.npmjs.org 20 100.92.128.96 (100.92.128.96) 18.412 ms 21 100.92.128.61 (100.92.128.61) 7.759 ms 22 100.92.125.38 (100.92.125.38) 9.742 ms 25 100.92.133.49 (100.92.133.49) 7.865 ms 26 150.222.214.102 (150.222.214.102) 10.175 ms 27 99.83.70.195 (99.83.70.195) 9.859 ms The last couple of addresses belong to AWS, which seems to hint that it's an AWS problem. This has been going for a while now and seems like a routing issue in AWS. Is there anybody being able to run npm in us-west-2?
