After I reboot my Ubuntu server I am not able to login via SSH. I have to go on site to login (using CLI) then I have the ability to login remotely. How I cane solve this issue.
I have installed SSH every thing works fine, only after rebooting the server I have to connect the screen and keyboard to enter username and password, then I can return to my office to login remotely
I had the exact same issue, and it was probably due to power management. After the reboot, the server slept after few minutes. Logging in through console (maybe only switching to console by Ctrl+Alt+F3) temporarily disabled this feature, but it was restored by the reboot.
After switching it off (How do I disable my system from going to sleep?), problems disappeared.
Assuming you have installed openssh-server, it will start from
/etc/init.d/ssh
If the server has been installed and the
/etc/init.d/ssh
file exists but doesn't seem to work, I'd execute a dpkg-reconfigure openssh-server.
