[dogeoffr]

Hello,

sorry if this has been covered before but i have not found a working solution in older posts.

in our agent conf file we do have AllowRoot=1 and when running dmidecode we do get system informations.

Any suggestions?

Thank you!


# zabbix_agentd -f -t system.hw.chassis[vendor]

run zabbix-agent as root? that is necessary for this!

Thank you for replying, to answer your question, yes we are running the agent as root.


Zabbix dev already identified the issue ->

It should be related to this:

/dev/mem protection

Some applications (Xorg) need direct access to the physical memory from user-space. The special file /dev/mem exists to provide this access. In the past, it was possible to view and change kernel memory from this file if an attacker had root access.

The CONFIG_STRICT_DEVMEM kernel option was introduced to block non-device memory access (originally named CONFIG_NONPROMISC_DEVMEM).

https://wiki.ubuntu.com/Security/Features#dev-mem

I believe they have a fix already accessing the info through an alternate target.

Thank you!

Good afternoon, I have the same problem, system.hw.chassis does not work zabbix_get gives an answer ZBX_NOTSUPPORTED: Cannot obtain hardware information.. At the same time, demidecode normally shows information. zabbiks_get run on behalf of the root.
