Dear all expert,
I have implemented CentOS server as my Telephony gateway after completed It working fine but a few month after It have issue with SSH. I try to remote to server by putty but it show message ( ver unexpectedly closed network connection)
I can’t remote to server but I can log into server directly by VMware client. I did a server reboot and after reboot it can log in as normal but a next few day It become the same.
