[GE users] I need help badly.

Lots of ways to replicate directories on Linux, 'rsync' is a great
tool for doing this and it can run over an encrypted SSH tunnel which
makes it useful to use across the internet or to internal machines
that only have SSH exposed through a firewall.
This may work for you instead of 'scp'
On your qmaster host and running as root:
# rsync -avz -e ssh /sge root at centos2.hyper.com:/sge
That will do a recursive directory copy via SSH to the 2nd machine
That said though, much like the gentle encouragement you got from
this list to use SGE 6.0 you'll find that things will be a lot easier
to manage, administer and debug when you are sharing your SGE
directory via NFS to your cluster nodes. In addition to making
installation easier this also means that all your configuration data,
spool logs and other core files are in a single easily-checkable place.
In addition to the sharing of SGE most people also NFS share the home
directories of the users as well. From a user's perspective, things
are much much easier when the home folder is shared and consistent
cluster-wide. If you are going to go through the trouble of sharing "/
sge" or something then you'd also probably want to share out "/home/"
Setting up NFS is not a big deal but you don't want to run any type
of NFS server exposed to the internet. You referenced a hostname of
"centos2.hyper.com" so I want to make sure you are doing this
internally or over a private network first. Since you are using
Centos, just surf on over to the online manual located at http://
www.centos.org/docs/4/html/rhel-sag-en-4/ and check out the chapter
