Hello, I need to solve this problem for my bachelor thesis. I want to run ubuntu ami on EC2 and use it as a remote DHCP server. This has to be within the free tier so I can't use elastic IPs and also NAT. I'm running Ubuntu 22.04 LTS with public IPv4 assigned and an access security group configured. Should I use EC2 public IPv4 address as default gateway when configuring DHCP? In theory it should work with the configured ip helper address from the remote router (my local router). Do I need to worry about AWS because they only route unicast? If you have any advice I will be grateful. Thank you very much for any answers.

Why is Fail2Ban completely missing from AL2023 repos? Are there instructions, including dependencies for hand installation on AL2023? Why would Amazon leave this standard component of basic hacker prevention and security out of the stack?
Hi there, I have some linux instances running on AWS but sometimes when we try to connect to the instance its say "Network connection failure" and same when I check on AWS EC2 console its says 1/2 status check failed. and after rebooting the instance sometimes its works perfectly and sometimes it got completely disconnected and after this we have to recover the data from EBS volumes and required to create new instance. But the previous instance was not in work. Please provide me a solution, why it is happening?
I have a Lightsail instance running ContOS 7, managed by WHM but I would like to upgrade to Almalinux 8. If I 'elevate' via cPanel's 'ELavate Project' (https://cpanel.github.io/elevate/) to Almalinux 8, will there be any repercussions?
Hello, my goal is to launch ec2 instances from Python code. For now I’m launching them by using launch templates. I need to create an alarm for each instance but I don’t know how to assign alarm to launch template(if it is possible). Maybe there is a different approach for that? The main idea behind alarms is that they will stop instance if it is inactive.

Hello Team, For the AMI ID ami-02f3f602d23f1659d (al2023-ami-2023.0.20230315.0-kernel-6.1-x86_64), I am seeing that crontab is missing [root@ip-172-31-11-172 ~]# contab -l -bash: contab: command not found After that I have installed the crontab manually using the command **yum install cronie cronie-anacron** But could you please let me know, Is the AWS missed to include crontab or hereafter the AMI will come up without crontab. Could you please confirm.

I've registered to Dedicated IP Managed service. Added 1 Dedicated IPs managed pool. Added this pool to the configuration set, and started to use this set when sending emails from my website. Hover emails still seems to be sent from old IPs, event these that seem to be on blacklists. I'm not sending a lot of emails, from few hundred a day to max 5-6 thousands. How can I check what IPs are added to my Managed pool? There is some link to cloudwatch but I cannot find anything in there. Also I don't think I would need mora than 1 IP, as I said I'm not sanding too many emails. AWS is recommending to stay with shared IPs, but it is not a good choice for me, as shared IPs are constantly being added to blacklists, and I have problems with some of IPS like hotmail, yahoo, icloud. Even if I have configured spf, dkim, dmarc properly.
