Hi,
I noticed a flood of ping processes hanging around on our library

I first thought that this epidemic has to do with the /etc/cron.d/loncapa
cron job. However, /usr/local/loncapa/bin/CHECKRPMS --cronmail
calls "ping -c1 -w10 ..." which should terminate properly, whereas the
pings above were called without the -w flag and therefore hang.
Does somebody know were those pings are coming from?
(the origin of the hangs comes from the fact that the pings did not go through
the firewall - I changed this for now).
This brings me to something else: I do not want CHECKRPMS to contact
ftp servers, I want it to look in /mnt/redhat as specified in the
check-rpms.conf file. It seems that CHECKRPMS ignores the check-rpms.conf
which I find rather undesirable. Is there a simple way of changing this
(before I dive in and rewrite CHECKRPMS)?
Cheers,
Martin
