Since this appears to have gotten filtered somewhere, I am posting it again.

Telnet, ssh, ftp, ntp, etc. depending on what services are running on the particular device. However, if the telnet port is ever unreachable, it changes its status to "closed" and then never changes back. I can telnet to the devices in question from the jffnms server, it just doesn't seem to realize it. Services on other ports behave themselves properly, and change their status back to "open" as soon as the device is reachable again. Can you run the poller manually so I can see the debug output? That does seem strange. - Craig -- When I came in this morning the board was all green. So, apparently it *does* time out eventually. I recreated the problem by the simple expedient of unplugging the cable from the back of the machine for one iteration. I have attached the output from the poller. Interfaces 4 and 9 are two examples of the problem. If necessary I can disable polling on all but one of the affected interfaces and run it again. A list of processes being run by the jffnms user shows completely empty after the poller completes. So it would not seem to be a case of the telnet program on the server getting stuck or anything simple like that. The server is currently Ubuntu 9.04. I have, however, noticed the same issue on previous versions. (On a different network that didn't use enough telnet for it to really catch my attention.) LMP - Laurence M.
