dhcpd not work..  :-\

Sounds like a stale PID got left behind somehow. Diag>Command, run:

rm /var/run/dhcpd.pid

Then browse to Status>Services and click Start. Suspect that'll fix it and it's unlikely to recur.

[yakar]

rm dhcpd.pid

not work :'(

[yakar]

There is not any error log in syslogs > System or DHCP tab..

[wallabybob]

@AydinY:

rm dhcpd.pid

not work :'(

Please elaborate: You got an error report on attempting to remove the file? (Did you actually type the full path given?)
The rm command didn't report anything and dhcpd didn't restart?

[yakar]

cd /var/run/; rm dhcpd.pid

dhcpd.pid is empty and deleted successful. Status > Services > DHCPD  Start..

im fixed error:

cat /var/dhcpd/var/run/dhcpd.pid
  hardwa

rm /var/dhcpd/var/run/dhcpd.pid

and Services > Dhcpd > Start..

why "hardwa" in the pid file? any have a idea?

[yakar]

i think this is a bug..

[wallabybob]

@AydinY:

i think this is a bug..

I agree.

There have very rarely been issues with stale dhcpd PIDs going back years, maybe happened a handful of times, and good luck replicating it. We don't touch the dhcpd.pid contents at all, whatever ends up in that file is put there by ISC dhcpd.
