Description Daniel Rowe 2013-07-22 07:02:03 UTC

Description of problem:

With selinux enabled and in enforcing mode collectd is unable to ping using its ping plugin.

collectd[871]: ping_sendto: Permission denied

Not that there are NO denials logged by selinux in either the message log or the audit log.

Setting SELINUX=permissive and rebooting fixes the issue and collectd IS able to ping.

Version-Release number of selected component (if applicable):

Completely up to date Fedora 19 system.

How reproducible:

Every time.

Steps to Reproduce:
1. Install Collectd and the collectd ping plugin,
2. Set collectd up to ping one of more hosts.
3. Watch the message log for errors.
4. Set SELINUX=permissive and again test the ping plugin.
5. Now works.

Actual results:

Collectd not able to ping.

Expected results:

Should work.

Comment 6 Daniel Rowe 2013-07-29 01:08:40 UTC

I initially thought the issue was fixed. But I was wrong. It still logging collectd[2837]: ping_sendto: Permission denied

Comment 7 Miroslav Grepl 2013-07-29 08:32:32 UTC

What AVC msgs are you getting?

Re-test and run

# ausearch -m avc,user_avc -ts recent

Comment 8 Daniel Rowe 2013-08-13 05:32:03 UTC

No AVC messages are displaying. It still logging collectd[5352]: ping_sendto: Permission denied

Comment 9 Daniel Walsh 2013-08-13 22:18:06 UTC

Try after semodule -DB, which turns off dontaudit rules.

semodule -DB
Try out collectd
semodule -B

Gather the AVC's related to collectd.

Comment 10 Daniel Rowe 2013-08-15 02:37:37 UTC

Pease see below the AVC message
