omshell reservation

[Thomas Markwalder]

Set flags value to 4:

A bit of bash:


omshell 1>$errfile 2>&1 << END_OF_INPUT
server localhost
port 7911
connect
new lease
set ip-address = $addr
open
set flags = 4
update
END_OF_INPUT



You should see the word "reserved" added to the lease:

lease 178.16.1.100 {
   starts 1 2020/07/20 14:00:00;
   ends 1 2020/07/20 15:00:00;
   tstp 1 2020/07/20 15:00:00;
   cltt 1 2020/07/20 14:00:00;
   binding state free;
   reserved;
   hardware ethernet 08:00:27:25:d3:f4;
   set remote-handle = %1;
}
