[syslog-ng] Issues running syslog-ng-ctl program locally to determine logging issues

[Evan Rempel]

You can add the option

--control=/your/location/syslog-ng.ctl

to the syslog-ng instance, and add the same option to the syslog-ng-ctl program.

Be sure that the user you run syslog-ng as has write permission in the directory  /usr/location

I am running syslog-ng as a local non-root user (I have it installed to a local instance under my home directory) and am trying to use the syslog-ng-ctl program in order to diagnose why certain log files are not passing through syslog-ng to their log destination (trying to rule out if it is a problem with the location where the logs originate OR if there is an issue with the syslog-ng setup and it is dropping or

However, when I try to run syslog-ng-ctl under my local account I get the following error, where it appears to reference a control socket that is located in a directory that is owned and operated by the root account (I should note that I am unable to sudo as root with my setup on the system).

This mailing list post also mentioned that running a local instance of syslog-ng-ctl should automatically create a local instance of the control socket file located in the /var directory where the local instance resides (so in my case, I imagine it would be

I tried touching the control socket file in that directory as a zero byte file, but still nothing

I’d really like to be able to use this tool to figure out what is going on with my syslog-ng setup. Let me know if there’s any other details or information that I can provide.
