Reproduce
- Connect via PuTTY by default
- Just run command
dir
in shell and repeat about 5~15 times - PuTTY may throw the Incorrect MAC ERROR
I dont know why PuTTY may received Incorrect MAC, but ssh.exe looks like OK. Maybe chose a difference encryption algorithm.
from fxssh.
Because PuTTY needs to send package [email protected]
, HERE https://tartarus.org/~simon/putty-snapshots/htmldoc/AppendixF.html. Some of synchronization mechanism goes wrong. (send a packet with repeating outbound packet sequence)
from fxssh.
But a ChannelFailureMessage is sent as the spec says.
I’ve seen this issue with the standard Ubuntu ssh client.
I think it might be related to multiple channels sending data at the same time and the crypto going out of sync

Hi @acid2000 , I pushed this commit 92bb558#diff-92634550b79326c13fac2679d286573fR374 .
Could you please test it is fixed or not?
from fxssh.
Anyone else found this question still exists?
from fxssh.
I patched session.cs on my build. Seems to fix the bug / I wasn't able to reproduce the original issue.
