DHCP server not starting by default after restore

I’ve already resolved the issue, but just in case someone else runs into this.

I did a full backup to ISO and installed it on a new device (to replace my existing IPFire device). When I finished configuring the new interfaces (only RED and GREEN on both) to match the new adapters after a reboot the DHCP server was not starting.

What was missing was the symbolic link in the rc3.d directory:

    # ls -l /etc/rc.d/rc3.d/S30dhcp
    lrwxrwxrwx 1 root root 14 Feb 15 22:40 /etc/rc.d/rc3.d/S30dhcp -> ../init.d/dhcp

All of the others were present and after adding the link everything works correctly now.

Thanks! I just hit exactly the same issue. I assume it happens when one does not enable dhcpd in the initial console setup (since I didn’t want ipfire handing out random leases before the static ones were restored from backup).

Having a quick grep of the githib source:

} else if (strcmp(argv[1], "enable") == 0) {
             safe_system("ln -fs ../init.d/dhcp /etc/rc.d/rc3.d/S30dhcp >/dev/null 2>&1");
             safe_system("ln -fs ../init.d/dhcp /etc/rc.d/rc0.d/K30dhcp >/dev/null 2>&1");
             safe_system("ln -fs ../init.d/dhcp /etc/rc.d/rc6.d/K30dhcp >/dev/null 2>&1");
} else if (strcmp(argv[1], "disable") == 0) {
             safe_system("rm -f /etc/rc.d/rc*.d/*dhcp >/dev/null 2>&1");

which suggests the easiest workaround in the GUI is to disable the dhcp service and then reenable it, and the actual bug fix may be to call this program from the backup restore script.


first, welcome to the IPFire community and sorry for the tardy reply.

Could you please raise a bug for this at https://bugzilla.ipfire.org/ (your login credentials work there as well) so we can keep track of this one and fix it? Please refer to this wiki page for further information on bug reporting, if necessary.

Thanks in advance, and best regards,
