Question

Related to case 4648365755 we have issue on our last Linux client.
Using suggestione posted in that case now we have managed issues on all our 20 Linux clients, but we have again issue on client mrvmvca01pl.
We have enabled SSH on installation server mrvmapl01cl (OB2_SSH_ENABLED=1), but whenn we try to install the DP client on client mrvmvca01pl from our windows cell manager mrvmdpt01pl we receive this strange error:
[Normal] Starting installation session on martedì 3 giugno 2014, 16.57.xy...

Answer

Issue:
On the Linux client (it could be a Cell Server)
Data protector installed but the client is not able to get telnet to, connection closed immediately without output and on the client, the inet remains in state TIME_WAIT:
[root@cmcentos ~]# telnet localhost 5555
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
There was the line:
ALL: ALL
in the /etc/hosts.deny
so all the connections will be rejected from the machine
added the line:
inet: ALL: ALLOW
to the /etc/hosts.allow
solved the issue
