DHCP releasing ip after 1 second

dhcpcd is giving me a valid ip address and everything but is realeasing it like 1 second after doing so.

dhcpcd -d eth0 && ifconfig && cat /etc/resolv.conf;ifconfig;cat /etc/resolv.conf

At the time of the first ifconfig and cat everything is ok but when i issue the second ones i no longer have an ip and nameservers.
I' using dhcpcd version 5.2.2 and the latest arch release.
What am i doing wrong?

PS:everything is working fine under freebsd 8.2 (dhclient em0).

Re: DHCP releasing ip after 1 second

Open up terminal, use su to become root.

Then use your favorite text editor, I like nano, and type: nano /etc/dhcpcd.conf

Omit the line that says "Respect the network MTU" (which is already omitted, but omit the second line, which is option interface_mtu).

I've had this problem before and this is indeed the fix, I submitted a bug report a while back, doesn't seem to be a daemon issue.
