[CoLoCo] Turning off IPV6 kills X

[Kenneth D Weinert]

but only sometimes.

Again - theoretically identical machines with very different results.

The back story.  My day job uses the Juniper VPN system. They (our
company) doesn't support anything but RedHat, so the install for this is
in an RPM.  I managed to fake it out (created a fake RPM first to get by
the openssl check) and then installed RPM and used alien to create
a .deb and installed it.

In some respects this works - I can get logged in, I get the IP
assigned, all that stuff. What I *can't* do is connect to another
machine on the network.  One machine I have to telnet to and the telnet
command resolves the address, but I never get a response from the remote
machine.

One of the network guys here (who is very helpful) took a look at the
output of ipconfig and netstat and the only thing that didn't match up
was the fact that I have IPV6 turned on (not using it, but it's the
default) and for some reason that I don't recall, IPV6 really messes up
something on our internal network.

So, from the following link:

http://www.ubuntugeek.com/how-to-disable-ipv6-in-ubuntu.html

I first turned off IPV6 on my work box, also Ubuntu and kept up to date.
Rebooted, all is fine.

So, I do this at home. Rebooted, it never comes back.  Tracking it down,
when the command 'hostname -f' runs in startx it just hangs.  Booting
into maintenance mode and running it from the command line does the same
thing.

If I go back in and put the IPV6 stuff back the machine boots up just
fine. I already tried the variation where I comment out the IPV6 stuff
from /etc/hosts and that had no effect.

I realize that this is most likely some sort of a network thing and it's
because the configuration is different between my home network (done by
an amateur) and the work network (done by highly paid amateurs with
experience :)

My question is this - does something jump out to any of you with more
network experience that could explain this?

Oh, and if anyone has experience running Juniper on Ubuntu successfully
I'd appreciate knowing about that as well.

Thanks.
