Oh, and if you reboot the server it'll load the default rules again - which are "allow SSH and that's it".
You need to do something like:

echo "# I did this to get rid of the default rules" > /etc/sysconfig/iptables

... as root in order to wipe the defaults.

OK, got the new version installed, turned iptables off (even though 'ps' didn't show them running) and seems well now.

I'm not sure what ps is supposed to show for iptables in this version, but it appears it's iptables that was stopping it.

Thanks all for all the help and have a great holiday.

See if

yum grouplist | less

gives you any ideas. then you can do, say,

yum groupinfo 'Development Tools'
yum groupinstall 'Development Tools'
yum groupremove 'Development Tools'

I'm installing 6.2 now. One thing I noticed is that I did not see the little
"network configuration" box on the install the first time. Once I get this
installed, I check iptables.

I'm using the "workstation" type install this time. Looking for something
that gives me the least post-install headaches. Once this is all done, and
I've got the grouplists installed, I'll see where I'm at.

The types of installation isn't very informative, for instance, does the
"workstation" install any server type apps, etc. This really belongs on the
Centos list up to this point, but since the basic server will end up with
MySQL, a mail server, HTTPD, PHP, and Perl, I was originally asking which
"type" of installation would get me closest to that configuration.

Thanks all,

You probably checked that, but the vm's NIC is in bridge mode, right?

Stop iptables and make sure you can telnet in. then work from there. yes

network configuration is different.

The host setup shouldn't matter. Are you able to telnet into the xen vm
on
port 25? have you disabled iptables or allowed port 25 through ? Verify
you
have connectivity from the outside first, then start working back on your
config files.

I've tried installing Centos 6.1 on a 5.7 xen host. I'm having a little
trouble getting sendmail to work, and I'm not sure why. Could be the way
the
network NIC is configured, the fact that I'm running 6.1 under a 5.7
host,
or who knows, but the server isn't accepting mail at all, even after
changing the line in the .mc file to accept mail from hosts other than
localhost and rebuilding the .cf file.

The new GUI for the Centos 6 installation seems to be somewhat confusing
when it comes to asking what type of installation I would like (types
being
things like SQL server, web server etc.)

I'm going to try the new 6.2 DVDs, but wonder what type of installation
others have chosen since I'm sure there's something closer than the
Workstation type I chose.

Thanks and sorry for OT
