Re: cygwin x11
xinit
twm
xhost +
This lets anyone on the planet connect to your X server and register to
receive X events, including keystrokes and mouse movements.
I'd strongly suggest being a little more restrictive in what hosts you
allow to connect ('xhost +' turns off host authentication entirely).

Re: cygwin x11
Xlib: connection to mylocalIPaddr:0.0 refused by server [snip] xterm Xt error: Can't open display: mylocalIPaddr:0.0xterm . You have to tell the X server to allow connections from the remote system. See man page for xhost. Xhost must be run from the machine running the X server (your desktop system). if i modify $DISPLAY to localhost:0.0, then xterm Xt error: Can't open display: localhost:0.0 appears when i issue xterm This will only work if the client is running on the same system as the X server and 'xhost +localhost' has been run. Since your Linux on Z guest does not run a X server (if it is, why are you wasting all those cycles when you don't have a display to manage?) this will always fail. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: cygwin x11
Bruce ... I run CYGWIN all the time, and mostly for X (since the company-provided machine is Windoze). When I do this, I don't necessarily use PuTTY, but I do often use SSH tunneling (which both PuTTY and OpenSSH supposedly provide). If you don't need the tunnel, then don't use it and connect directly to the CYGWIN system. But for this, you MUST allow remote access. Here is a script I run that brings up X on CYGWIN and takes it down again when I exit a controlling window. # clean-up from the previous run # (sometimes I get permission denied on this) rm -f /tmp/XWin.log # start X, and redirect for silence XWin -ac -emulate3buttons -multiwindow 0/dev/null 1/dev/null 2/dev/null # recover process-ID of X to kill it cleanly later XPID=$! # wait for X to come up and settle sleep 3 # set DISPLAY for this workstation DISPLAY=127.0.0.1:0 ; export DISPLAY # load my personal defaults cat $HOME/.Xdefaults | xrdb -merge # start an XTERM (this is the session master) xterm # when XTERM quits, we take down X kill $XPID -- R; -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: cygwin x11
Hi all, I got a another method to do it. start cygwin on windows box: xinit twm xhost + connect to remote linux box by PuTTY( enable X11 Forwarding) export DISPLAY=localip:0.0 xterm That's it.

This is part of what SSH does for you. You can verify this by: echo $DISPLAY localhost:10.0 The number may be greater than 10, but is definitely not 0... I remember there should be a listening port 6010 on the remote host, and DISPLAY=localhost:0.0, that's to say: the local cygwin is a X11-server, the remote host is a X11-client, remote host connect its port 6010 to local host's port 6000, so the display on the remote host will be redirected to local host. If there is not a listening port on the remote host that corresponds with your SSH session, then the server is not setting up its end of the X forwarding connection: either it is rejecting your SSH client's request because of configuration (sshd_config does not say X11Forwarding yes, since the default is no) or some other problem exists at the server. X display ports start at TCP port 6000. By default SSH starts allocating display numbers for forwarding starting at 10, which is why you see port 6010 tunelled through to your SSH client if your DISPLAY variable says :10.0. Because you may not be the first person to tunnel X via SSH on that host, you must always let SSH handle it for you (if you are the second, for example, you will get display number 11 and TCP 6011 will be tunnelled to you). If a TCP X display port is open against your sshd process but your DISPLAY variable doesn't correspond, check your shell profile scripts (/etc/profile, ~/.bash_profile, etc) for a command that sets DISPLAY.
