WHM 11.48.2 build 3 corrupted SSH server?

[goodbot]

My SSH server stopped behaving properly within the last day or two... when my putty 0.64 (latest) client (on Win7) goes through the authentication steps... as soon as a good password is entered, putty terminates the session... reporting "Connection closed by remote host"...

I'm able to continue making good connections to other non-cPanel hosts of mine without any trouble. Something changed in a recent cPanel update causing this new (config related?) trouble.

Any Ideas?

Have you tried accessing the same server from other device or network ? Also, let me know if you have saved your sessions in putty. If yes then that could be the reason try uninstalling putty and re-install it again.

If from another machine you are facing same issue then definitely there is problem with server end. You have to connect the server using kvm or IPMI and check the issue.

Hello,

Have you made any recent changes to your /etc/hosts.allow file? Note that you may want to try running a temporary instance of SSH to see if it allows you to access your server to investigate:

https://IP:2087/cpsess12345678/scripts2/doautofixer?autofix=safesshrestart

You would replace "IP" with the server's IP address and the session number with what's displayed in your address bar. Note that this is simply a temporary instance of SSH so you can login and determine what's wrong with the standard SSH service.

Thank you.
