Running the ZM binaries as a regular user?

Hi.

When I'm running any of the ZM binaries, as a regular user, I get no output (only help - but if I supply the correct parameters, it just exits and display nothing). When I trying to run them as a root, then I do able to launch them.

Any idea why it's happening, and how they can be launched via regular user account? (Note that all permissions are ok - in fact, they was compliled under the regular user, hence they have him as an owner.)

If you have run the binaries as root then the log files and shared memory segments may have been created as owned by root. Then if you try and run as a regular user they will not have permissions to access these resources. Make sure you delete old log files or shared memory segments that may be owned by root from a previous run before running as a different user.

Hi Phil.

Logs can be deleted pretty easily, but how should I free the shared memory? By stopping the ZM service?

Thanks.

It's best to stop ZM. This normally should delete the shared memory but may not always. Then use ipcs -m to list the shared memory segments and delete any remaining with ipcrm. The ZM segments should all have a key that starts with 0x7a6d20 so make sure you don't delete any of the other ones.

Hi again.

After turning the logging higher, I discovered that the actual error was because the /etc/zm.conf, in Cordel's RPM, was root/apache read only. Good security practice, btw
