Restart DHCP without reboot?

[werkstrom]

Hi,

Is there a way to restart the DHCP server without rebooting the router? Troubleshooting THIS issue with DHCP not responding and want to eliminate or confirm the DHCP service.

killall dnsmasq 
rm /var/lib/misc/dnsmasq.leases 
service restart_dnsmasq

I suppose you could also enact a restart by changing a DNS setting on the LAN or WAN page or some DHCP parameter like lease time.

The easiest way is to install scMerlin script. It will facilitate easy restart of major services including the DHCP.

killall dnsmasq
rm /var/lib/misc/dnsmasq.leases
service restart_dnsmasq

the last command will suffice on its own

I second this recommendation. Besides restarting DHCP, you can restart many of the services. Both from the WebUI and (my typical usage) from the CLI.
Forget to log out of the WebUI on one computer in your house? No problem, ssh in and restart httpd.
Make a change to ntp or chrony.conf? - a quick scmerlin and restart timeserver. For the life of me I can never remember the correct "service restart" commands.

Last, I can't explain in detail, but the Busybox "reboot" command is IMHO, not a good way to correctly reboot the router. "service reboot" must be doing some other magic. Again, scmerlin takes care of this ;-)

scMerlin was awesome. Thanks so much

service reboot is not available in scmerlin. Instead there is rr in amtm. Indee the service reboot command is doing the trick.

There's a "Reboot router" menu selection in the scMerlin CLI that calls "service reboot" as well.

Here's a screenshot showing this "Reboot router" option:

Thank you.
I did not search in the CLI because normally I use the WebIf panel (user3.asp).
It is a pity not to have it in the webif... at least I have not found it.
