Can't bind to dhcp address: Permission denied

twelvegates · #1 26th October 2005, 11:39 PM

I'm trying to launch dhcpd with root by /etc/init.d/dhcpd start.
But in the system log it claims:

Code:

Can't bind to dhcp address: Permission denied

But port 68 is not listened to by another process.
So what could be the cause?

Possible dumb question: Does the machine you're running the server on have a static ip address? It should.

There is an interface eth0 which has a dynamic address.
The interfaces that dhcpd should listen are tun0, tun1 and so forth created bye qemu. These interfaces have each a static distinct address. The address depends on the number of the interface.

Is SELinux on ?

Yes. It was the 'SELinux protection for dhcpd daemon'. After disabling it the dhcpd server can start as expected.
This feature can also be accessed in Gnome under Desktop -> System Settings -> Security Level -> SELinux -> Modify SELinux Policy -> SELinux Service Protection.
