UNIX for Dummies Questions & Answers

Why would you want VirtualBox to connect its graphical interface to the telnet server of the wrong machine?

Let me explain how SSH port forwarding works.

You tell SSH to forward a port on the remote host to a port on your local host.

When you connect to the remote server with SSH, the SSH server opens an extra port on the local host itself, waiting for you to connect to it.

When you connect to it, the SSH server forwards this back to the client, your client connects to whatever you told it to earlier.

So in effect, it creates a new port on the remote host, which connects it directly to X11 on your machine.

If you don't know what port number your X11 server is, you'll have to find out and forward it, since ordinary X11 forwarding doesn't seem to be working.

From wireshark

Code:

Internet Protocol Version 4, Src: 144.243.90.235 (144.243.90.235), Dst: 144.243.35.2 (144.243.35.2)Transmission Control Protocol, Src Port: telnet (23), Dst Port: 54025 (54025), Seq: 799, Ack: 166, Len: 1

So I tried

Code:

# DISPLAY="144.243.35.2:54025" ./VirtualBox
Failed to open the X11 display!

I have to be missing something in the setup of TeraTerm and Reflection X. I have Xming running in the background, is there a setting I missed?

So I have setup the display and am know getting a new error, I have Xming running

Code:

 DISPLAY=144.243.35.2:0.0
# export DISPLAY
# echo $DISPLAY
144.243.35.2:0.0
# cd /opt/V*
# VirtualBox
Xlib: connection to "144.243.35.2:0.0" refused by server
Xlib: No protocol specified

Failed to open the X11 display!
# cd /
# cd /usr/bin
# firefox
Xlib: connection to "144.243.35.2:0.0" refused by server
Xlib: No protocol specified

Error: cannot open display: 144.243.35.2:0.0

It could easily be being blocked by a firewall, which is the reason we were trying to forward ssh all along...

For that matter, is your xming even configured to allow non-local connections? Do you know what port you have Xming running on? 0.0 could easily be wrong if you don't know for a fact it is right...

0.0 is working for my coworker, he is also using telnet. He has been here for a while thought and is not sure how he configured it. I have defiantly gotten further in the setup. There was a problem connecting that was coming from SEP. That has been resolved and I was able to us Reflection to get a GUI desktop of the Solaris server, but it is slow. I also want to learn the command line ways.
