Something that you can do instead of a full blown lying DNS is to put the
host in the /etc/hosts file and change nsswitch.conf to look at hosts first
(the default on a Red Hat 7.1 install).
Hope that helps,
Adam

Subject: Re: proxies at wymount
The http_proxy variable is the "standard" location for the proxy
information. If a program fails to check there, then he will have to set
it in the configuration of the specific application.
I assume your application insists on connection to port 80 on the remote
machine, otherwise you won't have a problem with the firewall.
If the application does not support proxies, then you will have to
port-forward through the CS or the EE department using SSH, assuming you
can tell your application the host:port to connect to for its information.
Neither department blocks port 80. Something like:
ssh handel.cs.byu.edu -L 80:my.update.site:80
will establish a port-forwarding connection from your machine to handel at
the CS department. You must be root on your local machine to mess with
port 80 like this.
Then, tell your application to connect to localhost. If you can't do that,
then find out where the application is trying to connect. Then you will
need a lying DNS. If you configure your own system to be a lying DNS, then
you can tell your machine to tell your application that my.update.site is
really localhost. And so on, and so forth.
If you don't have an account on a machine that runs sshd and doesn't block
port 80, then..... well, find a friend who does and have him create a
tunnel from his machine to the remote (non-blocked) machine, and run a
tunnel from your machine to his machine.
Hopefully, all your applications will support proxies, so you won't have
to jump through any hoops.
