Re: [Condor-users] How do you add machines to the central manager?

[leo@xxxxxxxxxxxxxxxxxxxxx]

Still the problem exists. Is it really on DNS matter?...And how can I
set-up DNS? I am using three machines with Scientific Linux 4.3 OS (with
DHCP private IPs) and three machines with SuSE 9.3 OS (with global IP).
Can I set-up local DNS server and clients for these machines with mixed
IPs (local/private and global) and have different platforms/OS? How?
