Pranav,

Thanks for the help, but still no luck.  condor_status still gave me an
error which says
##################################
Cannot fetch ads from: <x.x.x.x:y> ...
CEDAR:6001: Failed to connect to <x.x.x.x:y>...

x.x.x.x is the IP and y is the port

I am not using "condor" user. is this necessary to create condor user? I
am just using my account and changed manually the CONDOR_IDS to my
account's UID.GID.

I already included the two machines' IPs in HOSTALLOW_WRITE and
HOSTALLOW_READ.

I can do scp and ssh (secure shell) on my machines. My machines were
configured by our administrator so that I can use ssh and scp.

the hostnames were already included in both machines' /etc/hosts.

What steps do I miss? :(

Or should I install NFS(Network File Server) and NIS(Network Information
Server) for this to properly work?
