Questions tagged with AWS Transfer for SFTP

Hey, Hope you are doing well!! I have created an SFTP server for transferring files from AWS to celigo integration middleware. But when I am using the credentials hostname, username & password not able to set up the connection on Celigo.IO integration middleware. It throws an error like the host is not exist. Can you please help me to get the correct credentials for setup & transfer files from AWS to another system? Thanks, Madhurilg...

[Transfer Family](https://aws.amazon.com/aws-transfer-family/) supports S3 and EFS storage targets, but a project's requirement specifies up/downloaded files be available to Windows EC2 instances via SMB (specifically a [FSx](https://aws.amazon.com/fsx/) share). I would let the EC2 instances mount the EFS volume used by Transfer Family, but [Microsoft](https://learn.microsoft.com/en-us/windows-server/storage/nfs/nfs-overview) says Windows NFS clients can only use NFSv2 or NFSv3. Since Transfer Family doesn't [natively](https://aws.amazon.com/aws-transfer-family/features/#Data_stored_natively_in_AWS_Storage_services) support FSx, is [DataSync](https://aws.amazon.com/datasync/) “between AWS storage services” the best way to support this workflow? As an added twist, we'll probably need to support both uploads (items that arrived via SFTP, consumed by the EC2 instances) and downloads (EC2 instance outputs a file, which will then be fetched by a remote user via SFTP) so we'll need to have [bidirectional](https://docs.aws.amazon.com/datasync/latest/userguide/other-use-cases.html#opposite-direction-tasks) DataSync between the EFS and FSx volumes.lg...

Hi team, I have a private VPC with all private subnets, I create an sftp server: - Protocols = SFTP - Identity provider = Service managed - VPC = my private VPC - access = Internal - Domain = Amazon S3 the objective is to allow the other team from the same corporate to load files into my s3 bucket. when I finish creating the sftp server, it doesn't give me an endpoint ==> (Endpoint = '-' and Custom hostname = '_') I just want to know how the other team from the same corporate can interact with the sftp server to put files on my bucket as my sftp server is not publically accessible and I don't have an endpoint URL to give them. so how can they connect to my server to put files? can they use clients like FileZilla or putty or winSCP ... to transfer files? Thank you!lg...

AWS Transfer Family now supports up to ten host keys per SFTP server. In addition, ED25519 and ECDSA key types are now supported for server host keys. Previously, AWS Transfer Family only supported one host key per server, and only the RSA key type. These enhancements allow you to move your existing SFTP servers with multiple host keys and host key types to AWS Transfer Family. You will also be able to add and tag host keys before rotating them, giving you more control over your managed file transfer environments. Multiple host keys and host key types are supported in [all Regions where AWS Transfer Family is available](https://aws-preview.aka.amazon.com/about-aws/global-infrastructure/regional-product-services/). You can configure server host keys using the AWS Management Console, AWS Transfer Family API, or AWS Command Line Interface (CLI). To learn more about how to add multiple host keys to an SFTP server, visit our [documentation](https://docs.aws.amazon.com/transfer/latest/userguide/edit-server-config.html).lg...

Hi , we have a mirroring setup ( get and put the file between two server by comparing on the either side wherever missing) by using the perl module . With Traditional Unix/linux server it is working good but when we try to use S3 for same file transfers it didn't worked at all. After multiple search got to know the below Change we have to do to make it work . my $sftp = Net::SFTP::Foreign->new('user@s-12345.server.transfer.us-east-2.amazonaws.com', queue_size => 1); we have added the above queue_size parameter in our code but it is working for very few files not more than 4 . If we try to put more files the connection starts stalling, the exact error is "Connection to remote server stalled" . when we are using the EC2 username and URl for file transfer it is working fine with any number of files like as we are doing with Linux/unix Datacenter based server. I want to know why S3 is not working properly . what is the difference between S3 and AWS . we have Network Packet capture done but no issue found as no packet loss was there . please help.lg...

I am new to AWS and looking for guidance to design a FTP solution Infrastructure : A zipped file (encrypted) plus a checksum file will be available on FTP server in Data Center 1 (once daily at around 1 am). Data Centre 1 cannot be reached via Public internet. But it has a connectivity to Data Centre 2 via MPLS. Datacentre 2 has Direct Connect Link Set up with AWS Ireland. Requirement: Get the zipped file from on premise server in DC!, and perform following : DEcrypting, perform check on checksum and DEcompression. Store the flat files (from zip file) in AWS London region in S3. These files will be required for 12 months and then deleted. These flat files wont be accessed frequently and will be saved for audit purposes. Only need to run the SFTP operation once on daily basis Pre Reqs Firewall ports will be opened No agent can be installed on any of the On Premise server Backup / DR solution required as well What is the best way to achieve this. I thought of using Lambda function but how will network side of things work. Can Lambda function be able to reach to FTP server in DC1 which is sitting behind a firewall. Can all the above operations (checksum, decrypt and decompression) be performed using Lambda function. We can create separate Lambda function for each operation. or to use EC2 instance and get node.js installed.lg...

Hello Team, I am working on a AWS Transfer Family Solution (SFTP) and need a confirmation that whether this service can support both password and ssh key based authentication at same time (i.e in one login attempt when user passes both using any sftp client like filezilla or winscp). I used lambda based identity provider and identified that when I pass both password and ssh key in Filezilla, password is never passed to lambda and so code logic have to assume it is ssh key based authentication. Can someone please provide any advise !!lg...
