Subject: c1auxex "Unknown Host" 

Quote:

c1auxex has forgotten who it is.  Slow sliders for the QPD head were not responding, so I did a soft reboot from telnet. The machine didn't come back, so I plugged the RJ45-DB9 cable into the machine and looked at it through a minicom session.  When I key the crate, it gives me an error that it can't load a file, with the error code 0x320001.  Looking that up on a List of VxWorks error codes, I see that it is:    S_hostLib_UNKNOWN_HOST (3276801 or 0x320001)

I'm not sure how this happened.  I unplugged and replugged in the ethernet cable on the computer, but that didn't help.  Rana is going in to wiggle the other end of the ethernet cable, in case that's the problem.  EDIT:  Replacing the ethernet cable did not help.

Former elogs that are useful:  10025, 10015

EDIT:  The actual error message is:

 We fixed this problem (at least for now) by adding c1auxex to the /etc/hosts file on chiara (following a hint from this page). The DNS setup might be the culprit here.
