I'll be honest, I don't really know perl well enough that I've made much
progress on getting the import script to read the bind files I have.
But, I found the rest API. Which seems a lot easier than trying to
script the web interface. I was able to use it import subnets from the
ospf information I had along with comments correlated from our hosts file.
I seem to be able to inport individual static addresses also using the
rest API. I have only imported a thing or two though because I want to
add forward and reverse DNS entries for those at the same time.
For that, I'm trying to figure out how the rr* objects work through the
rest API. The first thing I'm not sure of is if I want to create a
rraddr object, do I need to create a matching rr object first. (Same
thing for a rrptr object). Second, even if I do create a rr object
first, I still get a 400 http error code. I'm not sure if I'm including
all the required parameters (but I have modeled it after the xml I get
if I http GET netdot/rest/rraddr). Here's the python3/requests code I'm
using:
import requests
httpsession = requests.Session()
httpsession.post('http://holly.eoni.com/netdot/NetdotLogin',
data={'destination' : '/netdot/', 'credential_0' : 'admin',
'credential_1' : 'passwordhidden'})
# create rr
httpsession.post('http://holly.eoni.com/netdot/rest/rr',
headers={'Accept': 'application/xml'}, data={'active' : '1',
'auto_update' : '0', 'name' : 'draco', 'zone' : 'eoni.com',
'description' : 'erik_testing_rm'})
# create rraddr
httpsession.post('http://holly.eoni.com/netdot/rest/rraddr',
headers={'Accept': 'application/xml'}, data={'rr' : 'draco.eoni.com',
'ipblock' : '10.5.2.73', 'ttl' : '700'})
I have tried http GETting
http://holly.eoni.com/netdot/rest/rr?id=meta_data and
http://holly.eoni.com/netdot/rest/rr/meta_data in a browser to read the
documentation, but get a "System error" when I do that. (I've also tried
that for rraddr and rrptr). What parameters are required for rr, rraddr,
rrptr, (and while I'm at it, rrcname)? Do I need to create a rr first?
Does creating a rraddr create a matching rrptr?
On a side note, a lot of our reverse DNS for stuff that isn't static is
in a generic format, like 216-228-192-7. Is there a way to have netdot
create those entries on the fly (unless something is set for that
address in netdot)? Or should those each be put in as a separate DNS record?
Thanks,
Erik
