Help! Networking Problem with Linux and Unix over a Network Switch
 

Hello,

I'm having a strange issue with networking a Linux and Unix machine. The Linux distribution is Red Hat, and the Unix uses tsch rather than Bash. I'm trying to get the Linux to get access to the Unix's terminal and get visuals through X11 forwarding.

As of now, neither the Linux nor Unix has an internet connection. They're connecting directly through a network switch. They can SSH into one another fine, but lack X11 forwarding (for visuals) and I can't enable it as I can't download the SSH server and config files.

As a result, I'm trying to get the Linux to access the Unix through telnet (I know it's unsecure but like I said there's no internet connection). Normally you would just telnet onto the Unix and use the tsch command:
However, when I call this command and then try to open a terminal, it claims it cannot find the display. I already used "xhost +". I though the problem might be in xauth but when I try to generate a key (xauth generate) it once again claims it cannot detect the display.

Both computers have their networks up and both computers can ping one another, but for some reason the Unix simply can't detect the display of the Linux.

Any help would be welcome.

Xserver may be started with «-nolisten» by default, did you check if it binded to any port?

Thank you for your reply.
Unfortunately, I don't know how to check for that. Could you step me through it?
