Mike, grep localhost /etc/hosts shows: 127.0.0.1 localhost.localdomain localhost instead of loopback. The line in /etc/nsswitch.conf is "hosts: files dns". So, the first one needs to be exactly like you said for things to work?? Kevin Mike Schmidt wrote:
Kevin, Steve Emmerson fowarded me your support inquiry below. Normally, localhost is defined in /etc/hosts as the following; % grep localhost /etc/hosts 127.0.0.1 localhost loopback if that definition is missing, it can cause all sorts of unusual problems. If you find it is missing, add the above line back. If localhost *is* listed in /etc/hosts, make the following check; % grep hosts /etc/nsswitch.conf hosts: files dns to confirm that name resolution on your system does use /etc/hosts. Let us know if that resolves the issue. Going forward, please direct support questions to; address@hidden which will assist us in answering you more quickly in the event specific support staff are out of the office. Best, mikeFrom: Kevin Baggett <address@hidden> Subject: Question about computer at UW-SSEC Steve, I think (thanks to logging being turned on) I figured out why my LDM is taking so long to go on and off. The SELINUX keyword being disabled allows logging to work, but doesn't solve the slow startup/stop. So, after turning the LDM off, the following message shows in the log: Oct 25 21:21:54 stimpy ldmping[13141] ERROR: NAMED 12.000833 0 localhost can't contact portmapper: RPC: Timed out I've done a little poking around in the Log Interpretation page, but didn't see anything like this. In some of the archives, I see messages where "localhost" is a specific computer name. Where is this "localhost" being set - is it a configuration file variable? Thanks! Kevin Baggett UW-SSEC
