Agent can't retrieve process and interfaces information

[mad]

Hello,

As said in the title, the zabbix agent can't retrieve process and interfaces informations.

Here are a part of the log file :
4267:20070804:194208 Requested [net.if.out[eth0,bytes]]
4267:20070804:194208 Sending back [ZBX_NOTSUPPORTED]

In fact, non root users can't read /proc/{pid}/ and /proc/net/dev on my system :
mad:/$ cat: /proc/net/dev: Permission denied

The problem is :
dr-x------ 5 root root 0 2007-08-04 21:38 net
A chmod +r /proc/net/dev in root doesn't change anything.


Do you know how to solve this problem ? (I'm not quite confident in launching agentd in root)

OS : Debian 4.0
Kernel : 2.4.33grs-bipiv-ipv4-32

Thanks.
Mad.

Ok, the problem was that the security patch GRSEC was compiled in my linux kernel.

I simply removed it.
If someone has the same problem and want to keep GRSEC, you have to compile your kernel with these options (not tested) :
CONFIG_GRKERNSEC_PROC_USERGROUP=y
CONFIG_GRKERNSEC_PROC_GID=10
CONFIG_GRKERNSEC_PROC_ADD=y

These way the /proc files will be owned by root and readable by the GID 10.
You'll just have to add the zabbix user to this group.
