Re: XDMCP Session Loops connecting to HPUX, stalls connecting to Solaris, fromWinXP

["John B Visser/VISSJB/NON/INEEL/US" <VISSJB at inel dot gov>]

Thanks for the suggestions, I started a font server on one of the HP-UX
boxes, and using it, I was able to start XDMCP sessions to the HP-UX and
Solaris boxes.

I agree about using SSH, but all these systems are well behind the
firewall, so SSH isn't enabled on them.

John,

 >>From the xterm session, I first do a 'xhost +' and then 'XWin -query
 > 134.20.2.19 -from 134.20.174.113'.

First, follow the instructions in the User's Guide.  I know that you
aren't following the User's Guide instructions because you tried to run
xhost, which is not necessary:

Next, you should have searched the FAQ for Solaris, because you would
have found some things to try (which also might apply to HP-UX):

For future reference, telnet is *very bad*.  Telnet has no security,
whatsoever; even your password is sent across the Internet in plain
text.  Use ssh instead, which works very similarly to telnet and even
has compression:

http://xfree86.cygwin.com/docs/ug/using-remote-apps.html#using-remote-apps-ssh


One example command line to run from an xterm that enables X forwarding
and compression (which really speeds up X apps) would be:

ssh -X -C username@remote_hostname_or_ip_address


Let us know if the FAQ entries are helpful or if you still have problems.

You are welcome.
