I'm having trouble with dhcpd on my firewall/server serving a mix of
Windows and Linux clients. After running OK for several minutes/hours, it
keeps crashing with the following error and I can't seem to find the problem.
eg.
Nov 6 08:25:34 janus dhcpd[11758]: DHCPREQUEST for 192.168.7.36 from
b4:ae:2b:2f:b6:bf via em0
Nov 6 08:25:34 janus dhcpd[11758]: DHCPACK on 192.168.7.36 to
b4:ae:2b:2f:b6:bf via em0
Nov 6 08:25:46 janus dhcpd[24427]: Can't open f: No such file or directory
Nov 6 08:25:46 janus dhcpd[24427]: exiting.
When the client's lease expires they obviously cannot obtain a new address :-(
I have set:
dhcpd_flags="em0"
in /etc/rc.conf.local
I have appended my dhcpd.conf file and dmesg below.
I realise I'm running 5.7 and have not yet upgraded to 5.8 (this is
scheduled) but I've checked the errata and don't see anyhing pertaining
to dhcpd there.
Any pointers would be greatly appreciated.
