x server to use a specific ip with computer with many ip addresses
Hi can anybody clue me in here....? (reposting as it seemed to have not got posted) Imagine a machine with some real network cards (more than one), and fake (aliased) ip addresses, all work but having setup this I want to change the default x server's ip and use another instead having investigated sysconfig/googled it is easy to set up access control for x, but when i used the -from 1.2.3.4. command for xdm suse 9.2 decided to ignore it, gateway wise xdm choose the most direct route out hop wise. but an examination of /etc/X11 conf files seems to make seting x to use a specific ip address rather than another a troublesome affair. http://www.xfree86.org/current/Xserver.1.html#toc6 Can anybody point me to some wise hints since what i tried so far should work but somehow is being ignored Its not a security issue but it must be possible. Can anybody help/suggest/hint ? at what i'm failing to do here.

It sounds like you're trying to specify network behaviour at the application level. An X server runs on a host and is contacted via a port on a host. It's up to the network software to decide how to route packets between it and a client. What are you trying to do that you think needs you to specify an interface for the X server? And why don't you think you can do that in the networking subsystem? Cheers, Dave

Dave specifying that a will use x, and b shall use y is straightforward in say mail systems. Host is a fancy term for machine. The network subsystem does not seem to have a option to say x use this ip than another to and my knowledge, while a proxy would message the issue, firewalling too is not a good option either Theres got to be a way of telling X to use this ip a rather than ip b.

I don't know what a is, or x, or b or y. And we're talking about X servers, not mail systems. So this doesn't help me, or I suspect anybody else, understand what you're trying to do.

Indeed so. It's the term X uses, as it happens. I'm happy with either.

You still haven't explained what you're trying to do.

Why? That is, why do you believe that and also, why do you need to do it? As long as X can make a connection from client to server, why should it care how it's routed? Cheers, Dave PS Please don't copy me on replies.
