Hi,

I have a Fedora Core 3 system that was running dhcpd sucessfully untill a few days ago.

When starting dhcpd the following is displayed:

Please make sure there is no other dhcp server
running and that there's no entry for dhcp or
bootp in /etc/inetd.conf. Also make sure you
are not running HP JetAdmin software, which
includes a bootp server.

Bootp is not installed on the system
and there is no services currently listening on port 67

Thanks in advanced,

Problem was fixed by disabling SELinux.

was suggested at: Fedora Forums

How ever, I would like to re-enable SELinux.
Has any one else had this problem?
Does any one have a solution?

Cheers,

Matt

Is there supposed to be a question in there somewhere??

And don't re-open six year old threads, and tack questions on to the bottom of them. Open your own thread for your own question.

You should mark it as solved also.
