Hi,

...

--> I think you have to enable keek alive in both sshd_config and ssh_config, i.e. for the server AND the client.

Well, I use a windows machine to access this linux server. I access with putty, exactly with the command plink.exe, I don´t know where to indicate this in the client, do you know?

--> when you start "putty.exe" on your Windows client, you can change the settings for a specified connection (user@host). These settings are then also used by the other programs of the PuTTY suite like pscp.exe and probably also plink.exe Somewhere in the options under "Connections" you will find a check-box for keep-alives. Good luck!
