conn test stuck on red
list Leon Volfson
Hi, I'm using version 4.3.0-beta2 on Ubuntu 8.04.1 server. I've experienced some ISP networking problems this morning, which made Xymon mark all the connections red. After a few minutes the network went back to normal, but the red "lights" stayed on. It was only the conn test, all the other including telnets to port 80 were green. I tried restarts and such - nothing helped. The only thing that did help was "apt-get dpkg-reconfigure". The one thing that I did notice is that it always tried to ping an OpenDNS server, as this is the one I have in resolv.conf. What I wanted to ask is if there are any ways to remove some cache or temp files instead of doing dpkg-reconfigure as it's a bit of an ugly solution, although absolutely clean and fast - took me 5 seconds without loosing any data. Thanks, Lenny. P.S. btw, I still have a problem with ms-sql and ftp ports always red, no matter what I do. Any advice on that?

Don't use OpenDNS for name resolution on a monitoring system, as the false positive results will hurt you ... Or, if you must, use the 'testip' option for every host in bb-hosts.

Well, the things that could have made a difference here are: -restarting hobbit -invalidating any (non-hobbit) name resolution caches (e.g. nscd etc.).
