can't bind local address

Hi,

I get this message when i try to run Pen with this command line :

pen kdo.server:80 -r -a -f -d kdo.ws:80 192.168.0.87:80 &

I'm running Linux Fedora Core 5.

kdo.server and kdo.ws are specified in /etc/hosts as 192.168.0.79 and
127.0.0.1 respectively.

192.168.0.79 address is provided by DHCP

NB: when i run Pen with this command line :

pen kdo.server:8080 -r -a -f -d kdo.ws:80 192.168.0.87:80 &

all is OK, but i want Pen running on port 80 ...
