I work with different versions of Asterisk on quite a few servers, and on each one of them every 5 minutes exactly I see on the CLI “Manager ‘admin’ logged on from 127.0.0.1” and immediately afterwards “Manager ‘admin’ logged off from 127.0.0.1” (on some of these servers I get “Manager received command ‘Status’” and “Manager received command ‘Logoff’” in between). Does anyone know of a process that does this? It seems that the Flash Operating Panel does something similar on FreePBX, but this is not the case; there are no cron processes that run every 5 minutes either. On Asterisk 1.8 these manager connections often result in a “Broken pipe” error, and in order to solve it I need to find the script that initiates the connection.
It sounds like Munin is running, it polls the systems every five minutes.
In addition to that, a couple of the asterisk_* scripts fail to read the response after issuing the logoff command and result in the broken pipe message. Look in /usr/share/munin/plugins for the scripts.
You say there are no cron jobs running, however many people overlook the fact that there is more to cron than just the files in /var/spool/crontab.
Do you have any files in /etc/cron.d?
Which distro are you running?
Ian, some of our servers don’t run httpd at all but they still have these connections every 5 minutes. It’s indeed a raw vanilla asterisk install, performed by different people at different times.
dalenoll, no files in /etc/cron.d. All of our servers run different versions of CentOS.
