Putty sessions abort intermittently Error software caused connection to abort.

[pushpak.lele]

Hi,

Recently we have migrated to FTD 4100 from ASA 5585. Our system team runs scripts on the server using the putty session to the servers these scripts runs for hours .Earlier with 5585 these ssh sessions used to work properly but after migration these sessions abort while the scripts are running. We tried fast path but problem still persists.

Thanks and Regards

You might need to increase the tcp connection timeout value. The default is 1 hour.
