    Does this answer your question? Can't ssh, connection terminates immediately with exit status 254 – pLumo Apr 17 '20 at 6:50
  • Some of the answers required to run some commands such as changing 'UsePAM yes' in /etc/ssh/sshd_config, but the problem is there is no other way to login to machine except ssh. I cant fix it. I cant run those commands in remote machine – Mohan Apr 17 '20 at 7:19
  • but it is a local machine? So you could attach the disk to your other computer and change it from there? – pLumo Apr 17 '20 at 7:20
  • No its a remote machine, I am using VPN connection. – Mohan Apr 17 '20 at 7:26
  • Use the web interface of your provider or ask the support. Whatever you do when you have no access... – pLumo Apr 17 '20 at 7:33
