PuTTY: Strange packet received: type 3

Written early in the morning in English • Tags: , ,

Direct connections from PuTTY to Cisco routers kept dying on this error, so I finally ran a search. The workaround is to disable re-key on the SSH session. In the PuTTY settings dialogue, goto

Connection > SSH > Kex

Change the following values to zero:

Max minutes before rekey: 0
Max data before rekey: 0
