Informix hostname resolution

Hi, we've had a little problems show up this morning. Our operators have been trying to run the logical log backups this morning, and were presented with this error:

Server is in an incompatible state or user authentication failed

I've checked the online.log, and I'm getting a lot of these:

11:00:06 listener-thread: err = -956: oserr = 0: errstr = (informix@ad90c63): Client host or user (informix@ad90c63) is not trusted by the server.

The hostname ad90c63 is nonsense. How does informix resolve this name? I sort this pretty quickly or the logs will fill up.

PS I'm no DBA, so be gentle if you're talking informix 'speak' ;o)

Re: Informix hostname resolution

Found the problem, it seems that after a reboot the system enabled a previously disabled NIC.

Hi Robin,

it is not good that system enabled an old NIC.
Check /etc/rc.config.d/netconf for all lan cards configured and /etc/hosts.

Best regards,

Re: Informix hostname resolution

Yep, for some reason the second NIC was in the netconf file. So I've commented it out, and removed the device file.
