apcupsd is only suppose to work with APC's UPS's and the apcupsd developer will not deal with complaints about UPS's from other manufacturers.

This error sounds familiar. If it is the same problem I've had a couple of times, every time it happens, I forget what it was I did the last time to fix it. :-( After I remember, it seems almost obvious. Assuming you've got the same problem, you need to log into the account remotely, with out a GUI interface, or as another user. See if you have a file ~/.ICEauthority. If it is there, delete it and then try logging in again. I think that is the right file for the problem I've had.

Re: [CentOS] Re: sendmail aliases
The excuse given for removing the automatic update of the aliases database file was that it was a security issue. The thought was that someone could tapper with the file and cause problems. However, all these files are checked for proper file permissions and if they are not set correctly, sendmail will not work or at least give a warning. If someone nasty has permission to change the aliases text file, then they have permission to reck a lot more havoc on your system anyways and this change isn't going to help any. Personally, having sendmail do it itself is safer than me doing it manually. What if I'm in the process of updating the file at the same moment sendmail needs it. Sendmail could read a partial file and cause more problems. I see this already with the access file. With sendmail doing it on it's own, I don't have to worry about it.
