Enabling tcp ports for access

[Joe Profaizer]

I'm trying to figure out why I can't telnet (just for testing purposes) to port 8910 on one of my HP-UX 11.11 servers, but I can telnet to my other system. There are no entries regarding port 8910 in my /etc/services file. Is there some allow/disallow file for tcp port access? Or can you tell me where to start trouble-shooting?

Thanks in advance.

Is something else listening on that port??
netstat -an|grep 8910
lsof -p tcp:8910
lsof -p udp:8910
About /etc/services entry, it is not a must, an application can have it hardcoded. You may want to check /etc/services and inetd.conf to look if anything is listed there that uses this port.

Thanks RAC, but no avail. I don't see anything using such port.

What command you use to test that port??
did you check with lsof, if that porting is listeneing or not??

If nothing using that port, that nothing will answer to your telnet ...

What is the output of lsof on the other machine?
