cactid only runs properly as root.

[pbrubaker]

Hey all,

I have a problem that pertains only to cactid, if I use cmd.php the problem does not exist. If you run cactid as root this is the output.

Code: Select all

However if you run it as cactiuser this is the output.

I am running...

Linux 2.6.12-2.3.legacy_FC3smp #1 SMP Sun Feb 19 08:53:09 EST 2006 i686 i686 i386 GNU/Linux

cacti-0.8.6h.fc3.i386 (Installed from RPM.)
cacti-cactid-0.8.6g (Compiled source.

PHP 4.3.11 (cgi) (built: Nov 8 2005 06:24:40)
MySQL 3.23.58

I do have the MySQL permissions setup correctly and the cactid configuration matches the config.php configuration.

I must be missing something. For now I am running poller.php with root permissions but I would like to change that.

Any insight?

[pbrubaker]

Actually I think I found the problem. The either the install of cactid or an initial running as root (or both) improperly sets the permissions of:

Code: Select all

/etc/cactid.conf
/var/net-snmp
/var/net-snmp/cactid.conf

The default install of net-snmp sets the permissions of /var/net-snmp to '700'. It seems kind of hokey that cactid wants to store something there. Perhaps it should be storing that data elsewhere, like somewhere it has write permissions to?

Anyway, I've changed the permissions of the aformentioned files and directories so that cactiuser has the proper permissions and everything works now.

Just so people know how to fix it these are what the permissions/ownership should be set to.

Code: Select all

-rw-r-----  1 cactiuser cactiuser 2.5K Apr 30 18:33 /etc/cactid.conf
drwxrwxrwx   2 root    root    4.0K May  1 21:35 /var/net-snmp
-rw-------  1 cactiuser cactiuser 664 May  1 21:35 /var/net-snmp/cactid.conf

With those permissions 'cactid' run as 'cactiuser' outputs.

Actually, now I'm having another problem. I have no idea what's going on here...

Any ideas?

I think I figured out this one as well.

When cacti is installed via rpm it adds /etc/cron.d/cacti but the docs tell you to put the poller.php line in /etc/crontab. So I had both. The reason that it was working for a while was because I had it running as root in /etc/crontab and the other one (ran as cactiuser) failed because of the above error.

When I fixed the above error they were both running properly at the same time. Removing the duplicate execution seems to have fixed the problem.

Sorry for all messages the forums!

You're not the first one. This is a common problem for rpm based installs
