<![CDATA[Dhcpd refuse to start after upgrade from pf 2.4.4 to 2.4.5. Help Please!]]>Hello All,

I need your urgent advice to my problem.
DHCPD will not start, after the upgrade.

2020-04-12_14-25-45.jpg

Is anyone experienced any issue with DHCPD, the daemon will not start not matter what,
after I upgrade my pfSense from 2.4.4 to 2.4.5.

I have set my service watchdog to restart dhcpd if it has crashed.
But this method won't work either.

Manually click the button to start the dhcpd, did not want to start.

Below is my dhcp log:

Help Please! on Fri, 17 Apr 2020 11:54:43 GMT]]>To fix this problem of mine....

  1. Since pf already updated to 2.4.5, with the packages installed and running fine, except dhcpd
    was not running. I did a back up the configuration xml file. This configuration xml file will have
    all my settings incl. pf and its packages.

  2. I did a refresh install, and then got my PPPOE working first.

  3. I did a refresh install on my packages all of them, 1 by 1 installed them. Note that if PPPOE is not working,
    then needless to say, downloading and installing packages would not work at all.

  4. After installing the packages, reboot the system, now grab the configuration xml file and restore it.

  5. Once finished restoring the xml file, the system will automatically reboot itself.

  6. log into pf, and you see a big message: pfSense is reinstalling the packages in the background.

  7. I left the system to do its work. I went away and did something esle while waiting for the system
    to complete its task of reinstalling the settings. It took about 2 hours.

  8. After 2 hours of waiting, my log in screen did not display the message. Meaning pf had finished
    installing.

DONE.

As you probably know, I would not post the question for help, if I know or how to
interpret the log, what was dhpd could not run.

@Wepee said in Dhcpd refuse to start after upgrade from pf 2.4.4 to 2.4.5. Help Please!:

The command '/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid igb1' returned exit code '127', the output was 'sh: /usr/local/sbin/dhcpd: not found'

/usr/local/sbin/dhcpd doesn't exit.*
No OS on planet earth can start something that isn't there.
Or, the executable file /usr/local/sbin/dhcpd is somewhat a core pfSense file.

To be back on track fast : do a re install.

Btw :

service watchdog to restart

Is always bad.
The service restart package exists - that all that there is positive about..You shouldn't be using it.
IMHO : I never saw pfSense process just 'die' for the last 10 years or so ...
