Shutting down and restarting the dhcp server via omapi

[Jürgen Dietl]

Hello,

thanx a lot for your help. I tried it with the following script:

#!/bin/bash

/usr/local/bin/omshell << END
server localhost
port 7911
key xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
connect
new control
open
set state=2
update
END

The log file:

Feb 24 16:03:14 xxxxxxx dhcpd: peer xxxxxxxx: disconnected
Feb 24 16:03:14 xxxxxxx dhcpd: failover peer xxxxxxx: I move from normal to
communications-interrupted


Feb 24 16:03:09 xxxxxxx dhcpd: Disabling output on
LPF/eth0/00:00:00:00:00:00/10.2.220.0/24
Feb 24 16:03:09 xxxxxxx dhcpd: Disabling input on
LPF/eth0/00:00:00:00:00:00/10.2.220.0/24
Feb 24 16:03:09 xxxxxxx dhcpd: failover peer xxxxxxx: I move from normal to
shutdown
Feb 24 16:03:14 xxxxxxx dhcpd: failover peer xxxxxxx: I move from shutdown
to recover

I will do some trace soon and try to see how the 2 servers communicate. Till
now it looks to me that the server that shuts down dont tell it to the other
server.

cu later,
cheers,
Juergen
