Can't bind to dhcp address: Address already in use
-
DHCP service seems to be working but I get this message at startup. I do not have any other server running. What is the explanation of this message?

Have you checked to see if you have a host with a static address on your network which falls within the DHCP range you've specified?
-
Thank you for your input on deciphering my message log for dhcpd.
I ran nmap to lping scan all computers on the subnet so no surprises. The dhcp range is only 10 addresses. I could narrow it down if it would help troubleshoot.
-
Have you tried changing the available address range? If you're only providing 10 addresses, you might see if you get the same error if you alter the range to start from one up from the top address of the existing range and end ten addresses up from there.
Just as an afterthought, the IP of your firewall isn't being included in the DHCP range you've specified, has it?
-
"Please make sure there is no other dhcp server running"
Do you have another router or wireless AP on the network?
-
I used dhcping to scan the entire subnet and only answer received was from pfsense. Since the message does not seem to be a problem I will move on. Thank you.
-
Well - I guess thats not the problem then. (-:

I have the same error in my logs. Running 2.2-RELEASE (i386). I am very sure there is no other DHCP server on this lan but pfSense. The range is 20 addresses. 100-120
I ran DHCPLOC to be sure. Below I asked for a new OFFER several times.

As you can see only pfSense (10.3.15.1) answered.
The statement " Can't bind to dhcp address: Address already in use" is curious. I also checked /etc/inetd.conf
and it contains:
tftp-proxy dgram udp wait root /usr/libexec/tftp-proxy tftp-proxyI am seeing this alot .. not just at startup
Any Ideas?
-
I'm not seeing it. For anyone running 2.2 and having issues my (perhaps obvious and not helpful) recommendation is try 2.2.1
-
I had the same error message as well, I fixed it by disable DHCP on all interface, make sure DHCPD is gone from services list. then enable DHCP again.
when I had the issue, services would show DHCPD is running, but clients do not receive IP, I see the same error message every time I restart DHCPD. the problem started after I setup HA and upgraded from 2.2 to 2.2.1. I am not sure which action triggered the issue.

robinxyz - You are the Man!!! Funny how rebooting didn't solve the problem but following your steps does. I had installed a 2.2.1 on my test box and was about to replace the production unit with it when I saw your response.
Thanks

I have this problem too, i have no other DHCP servers running either on the box or on the LAN

I made a fix to this by adding the package 'cron' and applying a job every 15 min with
/usr/bin/killall -9 dhcpd && /usr/local/sbin/dhcpd -cf /var/dhcpd/etc/dhcpd.conf -lf /var/dhcpd/var/db/dhcpd.leases
it is not a nice way but it works for now
-
have anyone found a better solution than the fix i made?
-
the "disable DHCP on all interface, make sure DHCPD is gone from services list. then enable DHCP again." method worked for me, and I have not had problem with DHCP since. Have you tried that?
-
I know this is a Old topic.
but i got the same error.

I do have an HP all in 1. I did do a scan and a print around the time when this happend. and when i wanted to go a website it didnt work when i checked in pfsense Unbound stoped. I could just start it again without any problems.
i will do when i get back another test where i turn on the printer and see if it will stop unbound again. i normally dont have the printer powered on at all only when i use it so i never had this Unbound problem.
if it does kill unbound again when i give a command to the printer/scanner then that is the problem. But no idea how to solve that.

norspang…thanks for your cronjob...it has saved me a lot of hassle...not ideal but gets the job done.
