Hi Michael, I'm sorry, I should have been a little bit more clear about this. The zabbix_agentd process runs as zabbix:zabbix indeed, but the so called "UserParameter" scripts run with user:group zabbix:root. Or at least, this is the output of such a script calling `id`: > uid=110(zabbix) gid=111(zabbix) groups=0(root) Where is the 'root' group coming from? The user 'zabbix' certainly is _not_ in the group 'root' on my servers!
So you're right: this bug is actually not related to the zabbix_agentd process, but to the scripts invoked by that process. The same holds for the problem with additional groups. Check the output of `id zabbix` invoked on a simple root shell and compare it to the output of the UserParameter script: > uid=110(zabbix) gid=111(zabbix) groups=111(zabbix),4(adm) Note that the user 'zabbix' actually is in the group 'adm': this way it is able to read mail logfiles from /var/log. However, the group 'adm' has disappeared from the `id` output from the UserParameter script? Regards! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
