Hi there, some of my users use putty to connect to my server via ssh protocol. After some time they get the above error message, and it could be that my CentOS-side configuration caused this. Do anybody has experience with this problem? - Gergely
I had that problem on a Ubuntu workstation a couple of weeks before the network card stopped working so I'm guessing on hardware failure..

Click on a profile you use Then click on load Then on the left goto "connection" Change "seconds between keepalives" from 0 to some number like 5 or whatever Save In general, You should now be fine. - rh
