SSH connection freezes until server rebooted
I have 2 computers running arch linux, my desktop and my laptop. When I try to ssh into my desktop from my laptop, everything works fine, but when I try to connect from my desktop to my laptop, everything works until I try to open vim. At that point, vim doesn't finish loading and instead clears the screen and gets stuck there. When I run ssh with
-o ServerAliveInterval=10, the connection drops after 30 seconds of this, because of no response from the server (?). Any time I try to ssh into my laptop after this, it hangs immediately after I type in my password, not even loading the bash prompt. Interestingly, I've noticed that only after this point, if I try to ssh from my laptop to my desktop, it has the same behavior of freezing immediately after the password prompt.
Here are the logs from different connection attempts:

Re: SSH connection freezes until server rebooted
everything works until I try to open vim. At that point, vim doesn't finish loading and instead clears the screen and gets stuck there.
I assume this means "open the vim installation on the notebook through ssh"?
I'd ignore the ssh condition for the moment, can you even ping the notebook?
Can you "ssh -T <notebook_ip> ls"? (this will open a ssh connection w/o a TTY, run ls and exit - you should™ see the directory contents of the notebooks users $HOME)
Next up: create a fresh user on the notebook (or lose your bashrc and vimrc, but a fresh account will get you there simpler) and see whether this still happens. If not, only move away the vimrc of your original user and see whether vim still acts up this way.

Re: SSH connection freezes until server rebooted
Is the laptop connected via WiFi? There may be a fragmentation issue at work here.
Another shot in the dark is, that one of your systems does not have enough entropy available for encryption. I'd suspect the laptop, but please check on both, when the issue occurs:

Re: SSH connection freezes until server rebooted
Thanks for the help
@schard, you were right, it was a fragmentation issue. Setting my MTU to 576 fixed it.
