Hi Forum,
Some month ago I installed the nethserver-asterisk module. I tried to remove from web frontend, but this was rather difficult. The nethserver module was removed while individual asterisk modules remained on my system. The solution provided by @mrmarkuz
helped, but there is still one ghost left. Something derived from asterisk sends more than 600 email per day… How do I get rid of those nasty shadows?
TIA
Thorsten
NethServer Version: 7.9
Module: Asterisk
I suspect the “ghost” is a cron job.
You may check root mails or /var/log/maillog to get more information and also check /etc/cron* for left asterisk cronjobs.
In which file do I need to look exactly?
TIA
Thorsten
I don’t know exactly but I assume in one of the cron dirs there’s a file named asterisk. The cron mails are usually sent to root so just check the root mailbox with Roundcube (set domain to local and login as root) to get more information.
Completely overcrowd with from=asterisk@ … to asterisk@, however it is something extremely regular supporting your cron-proposal. It runs 00, 15, 27, 30, 31, 45 of each hour.
Here is one hour excerpt from /var/lib/maillog, just lines containing asterisk (using grep)

No result for
grep -i -r "asterisk" /etc/cron*
(Contercheck: grip -i -r “anacron” /etc/cron.* gives corresponding results…)
Also tried “pbx”, “freepbx” and “free” as the search text -> no result for “pbx” and “freebpx”, whil “free” gives some lines contianing “…Free Software foundation …” in different files
-> No Idea which might be the relevant job
You check if the string asterisk is in the files content but it doesn’t show, if the file is named asterisk. You may use find instead of grep.
Cron job locations to check:
I allready checked the (not too long file list) and I checked the content of hourly files, of course 
find -iname "asterisk"
gives
./etc/selinux/targeted/active/modules/100/asterisk
./etc/e-smith/events/nethserver-freepbx-update/templates2expand/etc/asterisk
./etc/e-smith/templates/etc/asterisk
./etc/asterisk
./var/lib/systemd/linger/asterisk
./var/lib/asterisk
./var/log/asterisk
./var/spool/cron/asterisk
./var/spool/asterisk
./usr/lib64/asterisk
./home/asterisk
What about this one?
did not check -simply deleted it … (sorry, should have done that), see here
However
grep -i -r “spool” /etc/cron*
does not give any result leading to /var/spool/cron/asterisk …
In spool are the users (like asterisk) crontabs.
In /etc/cron are the system cron jobs.
17:07
grep -i -r "asterisk" /var/log/maillog > /var/lib/nethserver/ibay/backup/ecodms/asterisk.txt
NO RESULT 4 ASTERISK AT 16:45 and 17:00 - RADIO SILENCE
I KILLED THAT CAT …!!!
