Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Running ssh from Windows -> linux and I cant paste text larger than ~20 chars. If I do it hangs the session.

This is happening to others in the office using various methods to ssh. cygwin, mobaxterm etc.

It also does not happen with all servers, but the ones it does happen too, always hang.

Any ideas? Bit tricky searching for this issue on google.

Update (on the linux box):

ping -M do -s 1472 google.com # ok
ping -M do -s 1473 google.com # icmp_seq=1 Frag needed and DF set (mtu = 1500)

Windows:

same as linux

Update

this is not just copy / paste, it seems to have gotten worse and now most things crash the session. nano some_file.ext and it will sometimes hang, or cat some_file.ext will also hang the session.

Are you connecting to a local server or remote server? If remote, what is the nature of your router and internet connection? –  EEAA May 28 at 11:59
    
Seems to be a MTU trouble. Check the mtu of the server, router and workstation. –  kranteg May 28 at 12:14
    
@EEAA It is remote (although some other remote servers work fine), what exactly do you mean with the nature of them? –  dogmatic69 May 28 at 12:22
    
@kranteg see update on MTU, dont seem to be the issue –  dogmatic69 May 28 at 12:43
    
On your workstation, you can try to put a mtu to 1400 temporarily to be sure. –  kranteg May 28 at 12:47

So the problem seems to have come from an automatic update in untangle. No clue what, but after bypassing ssl on untangle it works again.
