Remote X, Get mouse with black screen
 
I am trying to setup remote connection between machines on the same network using X -query and no matter what I try I get a black screen with the mouse cursor. I am running Fedora 1. Also, when I get the black screen with the mouse cursor I know no other way of getting back to my local console other than rebooting. is there another way?

Hopefully this helps: XDMCP Howto

As for the local console, you can use <CTRL>+<ALT>+<Fn> to switch back and forth (it should be F1 for your local console and F7 for X)

I've seen that page before and followed it. I know have 1 desktop with Fedora core, 1 laptop with Fedora core 2 and 2 Virtual machines 1 is core and the other is core 2 and I have the same problem in all of them. I wouldn't be surprised if it's something right under me nose but "I just can no do it captain".
This is at the end of the log XFree86.0.log

"AUDIT: Sun Jun 6 08:08:31 2004: 12995 X: client 5 rejected from local host"

looking in google and what I find is instances where the cant even get startx going. All of me kit has no problems with local X, only when I try to connect to another remotely.

Okay, since I am going to be rebuilding my laptop anyways, I tried to configure it to serve up logins via XDMCP. After following that howto I wound up in the same situation (blue background with a mouse cursor). Now I knew that the laptop was listening for connections since I had
Code:
[root@verandi root]# netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address          Foreign Address        State     
...
tcp        0      0 0.0.0.0:6000            0.0.0.0:*              LISTEN     
tcp        0      0 0.0.0.0:7100            0.0.0.0:*              LISTEN     
udp        0      0 0.0.0.0:177            0.0.0.0:*                         
...
What finally solved it was this
Code:
[root@verandi root]# iptables -A INPUT -s odin.local -j ACCEPT
As soon as I did this, I got a remote login. Perhaps this is the problem in your setup?
