Thanks Ian,
I agree it smells very strongly like permissions, but everywhere I look the
permissions are ok.
/usr/local/bin/rateup is world executable.
Note that if I make a symlink to where MRTG (when run as mrtg:mrtg) expects
to find 'rateup' (which is in / ) everything will work but I'll get the
following complaints in my /var/log/mrtg.log:
2005-11-27 18:00:00 -- Started mrtg with config
'/usr/local/etc/mrtg/mrtg.cfg'
2005-11-27 18:00:00 -- Use of uninitialized value in concatenation (.) or
string at /usr/local/bin/mrtg line 720.
2005-11-27 18:00:00 -- Use of uninitialized value in concatenation (.) or
string at /usr/local/bin/mrtg line 744.
Of course, when run as root there are no complaints at all. It *seems* to
work, but I don't like running it when it complains. It's ugly and I'm too
much of a perfectionist.
Ugh, I don't know where else to look! :)
