Hi, ALL!

I run a 5 computer, Ethernet-connect, network at home -- Intel hardware --
running the latest stable Debian Linux release (woody).

Now, for X-windows, running, e. g.,

DISPLAY=<IP address of computer X on the network>:0.0 xlogo&

DISPLAY=<IP address of computer X on the network>:0.0 xlogo&

should -- assuming, e.g., that you're xhost commands are right, etc --

run xlogo on the local machine, with the window coming up on Computer X.

Doesn't work.

E.g., even on the LOCAL machine, running

DISPLAY=<IP address of local machine>:0.0 xlogo& --

or

DISPLAY=localhost:0.0 xlogo&

or various modifications thereof all fail, with the error message "Unable

to open display".

Running

DISPLAY=:0.0 xlogo& --

or just

xlogo&

xlogo&

works instantly.

Also, ping localhost (or <IP address of local machine, or all the above
variants>), works fine -- all at about the same speed.

??

<Please, if possible, email this directly to me. as well as sending to the
newsgroup -- I read the group less often than I should, due to time
constraints.  I'll post a summary of all relevant answers --
including the eventual solution that works -- to the group, no matter
what>

This problem probably needs a Debian linux guru -- my system has the
defualt settings, for a Debian linux woody installation.

Thanks a lot!!!
