When attempting to update our DHCP server via OMAPI, I'm getting a
strange/munged result attempting to set the option PXE.boot_servers.
I'm using pypureomapi as the OMAPI client - and here's the relevant
block of code:
import pypureomapi as omapi
import struct, sys
o = omapi.Omapi("ip.of.my.dns.server",7911,KEYNAME,BASE64_ENCODED_KEY)
msg = omapi.OmapiMessage.open(b'host')
msg.message.append(('create', struct.pack('!I', 1)))
msg.message.append(('exclusive', struct.pack('!I', 1)))
msg.obj.append(('hardware-address', omapi.pack_mac("01:50:56:9a:10:b8")))
msg.obj.append(('hardware-type', struct.pack('!I', 1)))
msg.obj.append(('ip-address', omapi.pack_ip("10.5.96.236")))
msg.obj.append(('name', "tur-esnode10"))
statements += 'filename "{0}"; '.format("pxelinux.0")
statements += 'next-server = "{0}"; '.format("tur-issmgmt1.massey.ac.nz")
statements += 'option vendor-class-identifier "{0}";'.format("PXEClient")
statements += 'vendor-option-space PXE;'
statements += 'option PXE.discovery-control 15;'
statements += 'option PXE.boot_servers 0 1 tur-issmgmt1.massey.ac.nz;'
msg.obj.append(('statements', statements))
o.query_server(msg)
This is the result that I'm getting in the leases file:
host tur-esnode10 {
dynamic;
hardware ethernet 01:50:56:9a:10:b8;
fixed-address 10.5.96.236;
supersede server.filename = "pxelinux.0";
supersede server.next-server = "tur-issmgmt1.massey.ac.nz";
supersede vendor-class-identifier = "PXEClient";
supersede server.vendor-option-space = "PXE";
supersede PXE.discovery-control = 0f;
supersede PXE.boot_servers = concat (concat (00:00, 01),
substring (gethostbyname (
"tur-issmgmt1.massey.ac.nz")
, 0, 4));
}
Can anyone point out where I'm going wrong here (i.e. why the OMAPI
update is resulting in boot_servers being formatted like this) ?
Elsewhere (in our static host definitions) we are just using
option PXE.boot_servers 0 1 tur-issmgmt1.massey.ac.nz;
With Thanks in Advance,
Patrick
