[Dave Chamberlin]

Hello,

Am running hp-ux 11.31 with oracle. Cannot start listener....HPUX error: 239 Connection refused. Nothing in the hosts.allow or deny files. telnet, ftp work ok. Any ideas? thanks

Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=PGMMis.world)))

Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=PGMMis)))

Error listening on: (ADDRESS=(COMMUNITY=TCP.world)(PROTOCOL=TCP)(Host=castor.merit.com)(Port=1575))

TNS-12545: Connect failed because target host or object does not exist

TNS-12560: TNS:protocol adapter error

TNS-00515: Connect failed because target host or object does not exist

HPUX Error: 239: Connection refused

Is something else already listening on port 1575/TCP?

netstat -anf inet |grep 1575

If you have the freeware "lsof" utility installed, you could use "lsof -i tcp:1575" to identify the process that is hogging the port.

Is castor.merit.com a valid hostname for this host? Does it map to (one of) the IP address(es) of this host in /etc/hosts, and/or in the DNS?
