:SELinux is preventing /usr/bin/python from 'write' accesses on the file /etc/dhcp/manager-settings.conf.
:*****  Plugin catchall_labels (83.8 confidence) suggests  ********************
:If you want to allow python to have write access on the manager-settings.conf file
:Then you need to change the label on /etc/dhcp/manager-settings.conf
:# semanage fcontext -a -t FILE_TYPE '/etc/dhcp/manager-settings.conf'
:where FILE_TYPE is one of the following: NetworkManager_var_lib_t, NetworkManager_var_run_t, user_cron_spool_t, net_conf_t, pppd_var_run_t, NetworkManager_t, afs_cache_t, sysfs_t, puppet_tmp_t, named_cache_t, NetworkManager_etc_rw_t, NetworkManager_tmp_t, NetworkManager_log_t, sysctl_net_t, root_t. 
:Then execute: 
:restorecon -v '/etc/dhcp/manager-settings.conf'
:*****  Plugin catchall (17.1 confidence) suggests  ***************************
:If you believe that python should be allowed write access on the manager-settings.conf file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep wicd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 4 Daniel Walsh 2012-04-05 12:00:41 EDT
Do we need to label /etc/dhcp/manager-settings.conf
 as net_conf_t?

chcon -t net_conf_t /etc/dhcp/manager-settings.conf

Will solve your problem
Comment 5 Miroslav Grepl 2012-04-06 02:06:57 EDT
What does 

$ rpm -qf /etc/dhcp/manager-settings.conf
Comment 6 klement.sekera 2012-04-10 05:23:28 EDT
$ sudo rpm -qf /etc/dhcp/manager-settings.conf
file /etc/dhcp/manager-settings.conf is not owned by any package
Comment 7 Miroslav Grepl 2012-04-10 05:52:30 EDT
How is this file created?
Comment 8 klement.sekera 2012-04-10 06:00:03 EDT
In my config, after countless problems with wifi & network manager, I removed the Network Manager and installed wicd.

Since I can see some wicd related info inside the file, I guess this file is either created as part of installation or as part of wicd runtime.
Comment 9 Miroslav Grepl 2012-04-10 06:05:51 EDT
I see it now

Comment 10 Jiri Popelka 2012-04-17 07:23:41 EDT
Miroslav, can you reassign this to either selinux-policy or wicd ?
This isn't a dhcp issue, is it ?
Comment 11 Miroslav Grepl 2012-04-20 08:16:54 EDT

> How is this file created?

Comment 12 Daniel Walsh 2012-04-20 11:10:05 EDT
Currently we have these labeled as /etc/wicd/manager-settings.conf NetworkManager_lib_t?  Have they moved?
Comment 13 David Cantrell 2012-04-20 14:31:04 EDT
/etc/wicd is the correct location.  This looks like a dupe of bug #754412.
