hi all:
I have recently received a server with SUSE 10 SP2 as the old sysadmin moved away of the department.
AFAIK there no firewall or apparmor running; just Oracle DB and some other stuff.
The boss asked to run xymon client on the server since we have a xymon server some time ago.
I got logged to the server uncompressed tar and compile with a regular user the client (local mode) and then install with a sudo -s.
So far so good; suddenly we came that the client weren't running fine since something don't allow even a localhost to 1984.
After a long talk with older admins; we found that the system was lockdown in a undocumented way (at least to me) ... and the system is on a network that filter most tcp/udp ports (from the xymon server network the only open port is 22/ssh port and icmp ).

So via yast2 I disabled the xinetd telnet daemon to run our xymon client on the 23 port. We are using a reversed ssh tunnel to let the xymon client send the data to the xymon server (https://en.wikibooks.org/wiki/System...se_SSH_tunnels).

I modified xymon client script to use port 23 but as soon I run the start command to the xymon client I see this error:

2016-04-20 16:46:50.231234 Whoops ! Failed to send message (Connection failed)
2016-04-20 16:46:50.231295 -> Could not connect to Xymon daemon@127.0.0.1:23 (Connection refused)
2016-04-20 16:46:50.231301 -> Recipient '127.0.0.1', timeout 15
2016-04-20 16:46:50.231306 -> 1st line: 'client report.linux linux'


When xinetd telnet daemon was running the telnet localhost return the common connection string...

So I humbly ask for some help to fix the problem.... this is my 1st SUSE box and since there is no SElinux or firewall processes I'm lost.
