Yes, it can be, but for these tests, fetchmail had been killed, as well as the tail -f on the file, so the file s/b be free of any impediments. I can add those niceties once this is working, because if I add them and they don't work, I at least know it _was_ working. > The responsibility of the > daemon is to close its current file descriptors for the log and open new > ones at the original location (creating a new file) and then start > logging to that one. Since /var/log seems to be root only territory, I create the original file and chown it to me since fetchmail, running as me, cannot create a new file there. This is why the copytruncate is used, I found it to be much more dependable than the "create 0600 gene:gene" directive, which seems to be rejected because it tries to do that as the user gene who doesn't have perms to create a file in /var/log. FWIW, copytruncate has worked well for exactly this function for several years now. > 3) Optionally compress the old log file and/or remove any log file > backups older than a configured number of revisions. > > > So my question to you is: are you sure that step 2 isn't where it's > failing?

That is why I'm asking for help, it seems to be misbehaving. ;-) -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
