QUERY REGARDING ISC DHCP CLIENT

[Glenn Satchell]

This looks like the culprit:

Nov 25 22:22:40 localhost setroubleshoot: SELinux is preventing 
dhclient-script (dhcpc_t) "read" to /var/db/dhclient.leases (var_t). For 
complete SELinux messages. run sealert -l 
5213ea25-1a6a-470c-ba8d-b1ce9663bb1a

SELinux provides manadatory access control to files, sockets, processes, 
etc. You need to read up on SE Linux and how to adjust the settings so 
that dhcpd can read that file. Until then it will never work.
