Version 1 of X server insecure: third-party X server

Purpose: Continue helping users who get the error message

    X server insecure (must use xauth-style authorization)

This page is devoted to those users who are using Mac or PC, with third-party X server software.

What happens when you bring up your X server?

I get a little window in the center of the screen asking me to log into the host computer.

You're running on a managed display. This should be easy. Look at X server insecure: display manager running for instructions.

I get an xterm on my favorite host, or I have to launch clients from menus or dialogs.

You're running a remote, unmanaged display. X server insecure: unmanaged remote terminal has further help for you.

Something else.

Post to the comp.lang.tcl newsgroup, and there are lots of people who can help. If you figure out what to do, by all means update these instructions!
