Hello:
I have a host running two KVM guests. The guests
use br0 and each has a static IP address.
I am trying to figure out if there is a way to
use snmpd on the host to measure the traffic
usage of the guests. I do not want to require
anything running on the guests since I do not
control

Change the port statement in /etc/ssh/sshd_config and restart sshd
Alternatively, you can make a port direction on your firewall, say,
from TCP port 1234 to internal IP 22. Then, you don't need to change
the server config.
My 2 cents.

Not sure what you mean. You could edit /etc/inittab, and have your system run
at runlevel 3, rather than 5.
Or you could uninstall Xorg.

Pretty much everything you need to know about SSH is on the Wiki here:

Why don't people use the Wiki? These same topics come up over and over

I dont think it is well

One more thing - you might want to look at authfail. After a number of attempts
to log in, it will add firewall rules to block that IP address.

As mentioned previously, requiring certificates, and not allowing
interactive logins, is safest.
But even if you decide to allow interactive logins, there are things
you SHOULD do.
Disable admin/root login.

Hi!
As far as I can see there is no kvm in the base repository but
the older version 36 in CentOS-Extras. Version 83 that belongs
to 5.4 is only found on the install DVD and CD-Set.
So it's different when installing kvm later with yum which results
in kvm-36 than choosing 'Virtualization' on DVD
