Does it fail to authenticate?
Does it disconnect after successful authentication?

Are you inactive during that time? Did you install any updates? Has the virtualization software been updated?

Any suspicious entry in dmesg, /var/log/messages etc. on your centOS VM box?

Thanks, Loc

hi
when i check /var/log/secure im getting :

Jan 23 18:01:09 localhost sshd[17461]: Exiting on signal 15 when i check the "/var/log/messages" there is nothing that says something about this signal my iptables is closed

also i authenticate and the disconnect happens after successful authentication.

signal 15 means "SIGTERM"... Someone has terminated sshd... Strange.
