[nflug] ssh/cygwin/remote X question

[Stephen Burke]

Hello all,

I have been kind of out of the loop here in nflug_land whilst this 
".mozilla" directory migrated around my network until it found a place 
where it was comfortable, a (relatively) recently installed BLAG 30K 
(fc3). The computer this system is on, however is mainly just sharing 
files and housing this mailbox, but is not one that I am actually in 
front of much.

So, I am trying to set up ways to see this mailbox from a more powerful 
box (the one I am usually in front of) which has a removable hard drive 
for using various systems, among them, another BLAG, windowsXPpro, and 
the suse8.2 where the .mozilla directory originally came from, which 
will soon probably be either gentoo or ubuntu.

On the BLAG system, I am trying to set up xhost, which will work as root 
(but puts me in the wrong .mozilla directory, naturally), but when I try 
to ssh over here as a user, I get:

$ ssh 192.168.0.104

I seem to recall having no problem with ssh to here before, so I'm not 
quite sure what is going on or how to work around it (or how to know if 
someone is doing anything nasty).

On the XP side of things, I have installed cygwin, which I was hoping 
would serve as my xserver there. IT has no trouble ssh-ing into this 
box, but when I try to do DISPLAY=x.x.x.x:0 (as well as x.x.x.x:0.0), 
export DISPLAY, etc. I get "Could not open display x.x.x.x:0", which is 
the error I was getting on BLAG before I opened a certain port in the 
system firewall and got it to work at least as root. I am not sure about 
the XP firewall thing, and everything I've found has been talking about 
SP2 tweaks, and I have been avoiding THAT thing like the plague. Any 
idea how I can poke a hole for this to work or even if cygwin is what I 
want to use for this?

Advice is always welcome.

Thanks,
S.
