My SSH session to AWS Ubuntu Server Hangs (hexbear.net)

Hi Friends,

I have an Ubuntu 22.04.3 server out in AWS that I can connect via Bitvise with no problems. However, when running any kind of command (ls, cat) the session hangs and restarts. The command goes through since when i reconnect, whatever task I put through is finished (I installed RT5) but now I can't edit files or anything.

Things I've tried: Made sure ICMP is enabled throughout my network and Security Group.; Also lowered the MTU on the server (default was 9001 and it's now 1422).

Here is a wireshark capture of when the DC occurs. Any thoughts on what this is? Any way to test where this breaks down?

I appreciate any help, thank you!

Does it work when you connect via a VPN?

Have you looked into AWS Cloudwatch logs? That's usually the best bet to see what's happening on the cloud side of things.

I set up a log group for that instance and it showed nothing.

I don't know if I set it up wrong or if just means things are fine on that side.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
