I keep getting the message dhclient: send_packet: Permission denied I try sockstat | grep dhclient and get root dhclient 247 4 udp4 *:68 *:* root dhclient 247 6 dgram -> /var/run/log I utter psgrep dhclient and get root 247 0.0 1.0 1812 1284 ?? Ss 2:13PM 0:00.26 /sbin/dhclient rl0 I've tried setting up special rules in the firewall to catch the dhclient packets, and the firewall doesn't seem to be stopping them. The ipfw rules to pass the packets are allow udp from any 68 to 255.255.255.255 dst-port 67 out via rl0 allow udp from any 67 to 255.255.255.255 dst-port 68 in via rl0 "ipfw show" doesn't register any packets even when dhclient is complaining about not being able to send packets. I can get an IP address, no problem. From the messages log: dhclient: New IP Address (rl0): <ip address> dhclient: New Subnet Mask (rl0): 255.255.254.0 dhclient: New Broadcast Address (rl0): <ip broadcast address> dhclient: New Routers: <ip router address> But even with this, I'm still getting the Permissin denied message. The messages log also includes this: dhclient: Can't bind to dhcp address: Address already in use dhclient: Please make sure there is no other dhcp server dhclient: running and that there's no entry for dhcp or dhclient: bootp in /etc/inetd.conf. Also make sure you dhclient: are not running HP JetAdmin software, which dhclient: includes a bootp server. In addition to the system generating these messages on its own, I can also prod it into generating them by uttering dhclient rl0 I'm not running HP JetAdmin software, and the dhclient setup is perfectly stock. I haven't installed any additional DHCP software. I'm not running a DHCP server. The only DHCP configuration I've done is in the rc.conf file: ifconfig_rl0="DHCP" I'm not using inetd. This has been a problem starting with FBSD 4.4 through 4.8. and with my current system, 5.2.1. I'll upgrade to 5.3 in a month or so when I have the time, but the problem seems to occur on all versions. I've searched the archives and Googled extensively, and I can find messages from other people with the same problem, but I haven't found a solution. It seems as though a second copy of dhclient is firing up and tryng to bind to port 68, and getting blocked by the existing copy of dhclient. Anybody have a clue what's going on, or why that would be happening?
