Description steven.vandervalk+redhat 2011-05-30 06:03:41 UTC
SELinux is preventing /sbin/dhclient from 'read' accesses on the file nm-dhclient-eth1.conf.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that dhclient should be allowed read access on the nm-dhclient-eth1.conf file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep dhclient /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 steven.vandervalk+redhat 2011-05-30 06:07:23 UTC
Apologies if improper, first bug report. Was having issues with NetworkManager not storing a config in system-connections for wpa2 enterprise wan and not connecting, so i removed NetworkManager.conf and that brought this.

Comment 2 Miroslav Grepl 2011-05-30 07:52:42 UTC
I guess you executed wpa by hand? 

What is your output of 

# ps -eZ |grep Network




You will need to execute

# restorecon -R -v /var/run/nm-dhclient-eth1.conf

But also you will need to start wpa using an init script.

Please reopen the bug if I am wrong. Thank you.

Comment 3 Dominick Grift 2011-05-30 08:29:33 UTC
Can you also: restorecon -R -v /var, just in case your /var/run symlink is mislabelled.

Comment 4 steven.vandervalk+redhat 2011-06-01 02:25:29 UTC
I guess so

system_u:system_r:NetworkManager_t:s0 942 ?    00:00:00 NetworkManager

Thank you.
