Description of problem:
Can't run dhcpd with valid config file. SELinux blocks it:

type=AVC msg=audit(1118774433.422:183565): avc:  denied  { name_bind } for  pid=2125 comm="dhcpd" src=67 scontext=root:system_r:dhcpd_t tcontext=system_u:object_r:reserved_port_t tclass=udp_socket

type=SOCKETCALL msg=audit(1118774433.422:183565): nargs=3 a0=6 a1=bfbb8fe8 a2=10

Here's the config file:

subnet netmask {
        default-lease-time 86400;
        option subnet-mask;
        option broadcast-address;
        option routers;
        option domain-name-servers;
        option domain-name "XXXXXXX.YYYYYYY";
        option netbios-name-servers;
        ping-check true;
ddns-update-style ad-hoc;

Comment 1 You 2005-06-16 12:51:08 UTC
I also have same problem. (so I guess this is a confirm).
My Details:

Try to connect to eth0 through 'USB CDC Ether'.

With selinux on no conncetion is made. Turning selinux off allows dhcp to
connect to the internet. (NTL cable modem in the UK).

Sorry, thi is the correct one.

Comment 4 Nerijus Baliūnas 2005-06-17 15:11:24 UTC
Bugs 159378 and 160790 are duplicates of this. It seems it is worth to try to
restart all important services before releasing new selinux-policy-targeted package.

Comment 5 Daniel Walsh 2005-07-11 18:44:46 UTC
Fixed in selinux-policy-targeted-1.25.1-7
