One address is 192.168.ish and the other two are assigned network addresses. Symptoms were that all the usual admin tools were haveing their create date updated at one minute intervals to stay current, and anything we tried to do with them was a segfault. And the machine was lagged terribly, with the cpu running 50F hotter than normal. Cleaning and regreaseing the cpu & heatsink only helped about 10 degrees. cpu fan is running good. So we did a reinstall (rh9) without formatting because there was a lot of non-replaceable data on it. This also saved the logs, but they are obviously not a lot of help when about 5 hours is missing at about the time everything went to hell. One of the things left visible in the logs was an ssh login by root, from one of its ethernet addresses to another, but without a corresponding root login from an outside address! Has anyone seen such a duck waddle by before? -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.
