Re: [Condor-users] Adding private network nodes to condor

["Natarajan, Senthil" <senthil@xxxxxxxx>]

Hi Mark,
Thanks for the Info.

I guess you are suggesting setting up individual condor pool for each private network and from the main condor pool, flocking the jobs to other private network condor pool right?

I was wondering is it possible to do with out setting up individual condor pool.

Suppose if we setup flocked pools, does the main condor pool will list all the machines form the all the pool, (i.e) the addition of nodes from flocked pools.

Thanks,
Senthil

Hi Senthil,

What you envisage should certainly be possible; we use a very similar
model here. In our case we have a number of flocked pools, with some
machines running only private IP addresses and others running both
public and private ones. However, Condor is forced to operate over the
private IP addresses *only*. Now, does your head node also have a
private address? It doesn't sound like it from your post, so I'm not
sure what you hope to achieve by setting BIND_ALL_INTERFACES. May I
suggest that you give the head node a private IP address too (it could
be a virtual interface; it doesn't have to have an extra NIC). Let's say
that this private IP address is 172.24.116.14. Then in your head node's
configuration you'd need:

CONDOR_HOST = head-hostname.my.private.domain
FULL_HOSTNAME = head-hostname.my.private.domain
NETWORK_INTERFACE = 172.24.116.14

All your other nodes don't need to nominate a NETWORK_INTERFACE, since
they only have the one. They just need to make sure to set CONDOR_HOST
to the same as above. Your pool should now work entirely via the private
IP addresses. Note that the head node also has a DNS entry in the domain
spanned by the private IP range.

Cheers,
Mark
