I tried to install and enable denyhosts on a fresh Fedora 15 install.
I did systemctl enable denyhosts.service. systemctl ran chkconfig.
When I started the service I got this in /var/log/messages:
May 29 07:49:33 murron setroubleshoot: SELinux is preventing /usr/bin/python from read access on the lnk_file /var/lock. For complete SELinux messages. run sealert -l fc8b6153-e359-409b-9310-9f0f3b3a20c7
sealert says:
SELinux is preventing /usr/bin/python from read access on the lnk_file /var/lock.
***** Plugin restorecon (94.8 confidence) suggests *************************
If you want to fix the label. /var/lock default label should be var_lock_t. Then you can run restorecon. Do # /sbin/restorecon -v /var/lock
***** Plugin catchall_labels (5.21 confidence) suggests ********************
If you want to allow python to have read access on the lock lnk_file Then you need to change the label on /var/lock Do # semanage fcontext -a -t FILE_TYPE '/var/lock' where FILE_TYPE is one of the following: var_run_t, var_lock_t, bin_t, cert_t, usr_t, device_t, devlog_t, locale_t, abrt_t, etc_t, lib_t, proc_t, root_t, device_t, ld_so_t, proc_t, denyhosts_t, textrel_shlib_t, rpm_script_tmp_t, var_run_t. Then execute: restorecon -v '/var/lock'
***** Plugin catchall (1.44 confidence) suggests ***************************
If you believe that python should be allowed read access on the lock lnk_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 denyhosts.py /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp
