Multiple Session Question
Hello, I've got cygwin working well via SSH to single host, single window. I connect via SSH, and run startkde - I get the KDE desktop in one single window. Works great! How do I connect to a second machine at the same time. See below for details. -Duane. For example: I login as my self - with ssh a remote session And I login as another person to the same machine. In my case, I have two accounts: A development account And A Test account. Likewise, I have this situation: I login to Machine1 - and it works. I login to Machine2 - and it works. Problem: I can only have 1 connection to 1 machine at a time. Both should have separate window/display. I have done this with commercial X11 packages, but not CygwinX. This does not seem to work, and I can't seem to find in the user docs any thing that reasonably describes some things. (1) Yes, I have tried using a different display, ie: 127.0.0.1:0.0 And 127.0.0.1:1.0 That does not work when I have 2 sessions. The two displays work - independent of each other (2) I'm not sure what is going on with the /tmp/.X11-unix/dir And can't find docs for it - I suspect it is part of the problem. (3) I'm not sure what the --screen options do for the Xwin program. The script I to start the session (via SSH and public keys) is below, The difference between the two is WHO and DISPLAY. The script below - deletes the old /tmp/.X11-dir, which I know is a bad thing with 2 sessions. I have tried not deleting it - that does not seem to help. #!/bin/bash TARGET=linxbox WHO=duane #WHO=testaccount export DISPLAY=127.0.0.1:0.0 #export DISPLAY=127.0.0.1:1.0 export PATH=/usr/X11R6/bin:$PATH export XAPPLRESDIR=/usr/X11R6/lib/X11/app-defaults export XCMSDB=/usr/X11R6/lib/X11/Xcms.txt export XKEYSYMDB=/usr/X11R6/lib/X11/XKeysymDB export XNLSPATH=/usr/X11R6/lib/X11/locale rm -rf /tmp/.X11-unix XWin -clipboard -silent-dup-error echo STARTING KDE REMOTEL ssh -l $WHO $TARGET startkde echo DONE RUNNING KDE REMOTELY exit -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
Modal windows
We have a MOTIF app that works correctly when displayed on a debian sarge (that is, using xfree) or win2k+exceed8.0. With cygwin-xfree on winxp, however, the modal windows do NOT stay on top of the main application window, the main comes up whenever one clicks in it. In all 3 cases, the client libraries are linux/xfree, at exactly the same version. Is that behavior - by design? - a known bug? - due to a user error? - a bug never reported yet?

RE: [Fwd: Re: Multiple Session Question]
No that does not work - session1 starts, then session2 - overwrites/destroys session1. Then it gets really weird Both are using the same display number (0.0) Besides, this is problematic in another way. I need to be able login/logout of the two accounts independently. -Duane. -Original Message- From: Reid Thompson [mailto:[EMAIL PROTECTED] Sent: Thursday, June 07, 2007 11:10 AM To: Duane Ellis Subject: [Fwd: Re: Multiple Session Question] failed to copy you on the reply to the list try #!/bin/bash TARGET=linxbox TARGETONE=linxbox1 WHO=duane WHO1=testaccount export DISPLAY=127.0.0.1:0.0 #export DISPLAY=127.0.0.1:1.0 export PATH=/usr/X11R6/bin:$PATH export XAPPLRESDIR=/usr/X11R6/lib/X11/app-defaults export XCMSDB=/usr/X11R6/lib/X11/Xcms.txt export XKEYSYMDB=/usr/X11R6/lib/X11/XKeysymDB export XNLSPATH=/usr/X11R6/lib/X11/locale XWin -clipboard -silent-dup-error echo STARTING KDE REMOTEL ssh -l $WHO $TARGET startkde ssh -l $WHO1 $TARGETONE startkde echo DONE RUNNING KDE REMOTELY exit -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

RE: [Fwd: Re: Multiple Session Question]

Holger Krull You will need Xwin :1 for the second and
Xwin :2 for the third session and so on.
That's the solution - I forgot - is the same way on linux.
Thank you very much, works *GREAT*
For those reading this (via a search engine), if it is not specified, the
default is :0 Which is Display 0,
Below is a resulting template script that works very nicely, for me, with
some limitations.
I could - via additional shell tricks, do the following:
1) In the directory: /tmp/.X11-unix/ are unix ?sockets?
(visible only under CYGWIN not via windows).
In my case, right now, I have these two files:
/tmp/.X11-unix/X0
And /tmp/.X11-unix/X2
Thus right now, Display 0, and 2 are active, yours may be different.
2) I could write shellscript stuff that finds a free display number
And uses that number - instead of hard coding the display number.
I'll leave that as an exercise for you, the reader.
3) Also - one must deal with cleanup of stale files laying around.
in some clean and graceful way.
=
Holger Krull But i wonder how your first connect works anyway, have you
setup ssh tunneling somewhere?
Yes, I have, via my ~/.ssh/config file - I have lots of things setup
Including X-11 forwarding, my identity file, etc. That way I do not have to
re-specify a zillion options everyplace I script SSH.
Again, for those reading this via a search engine, my ssh_config file looks
sort of like this I have many accounts, in this example I use R and X. Both
Accounts have different user names.
I could - specify -X, -L, -I, and -lots-of-options on every command line
everywhere I use SSH --yuck, and --double-yuck Or - I can use an SSH config
file (which hides/collects that sort of stuff in one nice little file.
Blow is an example short snippit of an ssh config file (maybe with typos), I
can type: 'ssh rrr' or 'ssh xxx' and it works just fine, see man
ssh_config for more details I could add other host entries - like: ssh
plant1 or ssh plant2 or ssh home and, if needed, with the cygwinX
shellscript (and a fat pipe) run X sessions from anywhere in the world.
File: ~/.ssh/config
Host rrr
Hostname rrr.someplace.special.com
ForwardX11 yes
ForwardX11Trusted yes
IdentityFile id_rsa_rrr

Assuming you're using multiwindow mode, each X window is rendered in a different Windows window. Unfortunately, modality in X is not the same as in Windows. In X, the display (server), window manager, and client are separate processes, and have clearly defined roles. This is why it's possible to move the parent of a modal window, because the client is not responsible for its window's placement. In Windows, the client process is responsible for handling windows movement events, so the entire parent window, including the frame is effectively iced. I think the decision was taken that rather than inflict Windows' arguably broken concept of modality on an unsuspecting X process, all X windows are created as non-modal Windows windows. The modality at the client level is still maintained (i.e. you can't do anything in the parent), but you will still be able to move the parent window about. If you really need full X-style modality, you should be able to use one of the other modes (rootless or fullscreen) and run an external window manager. The only problem with this IIRC, is that all X windows are really just images in a single Windows window, so clicking on any X window brings all X windows to the top. Note that Windows' notion of stacking order is completely broken. Always-on-top windows are frequently rendered on the bottom. This includes modal windows, which is just great if they are rendered completely beneath the now disabled parent window! -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
RH-EL-4 -vrs- RH-EL-5
Another problem has cropped up. I use CygwinX with RH-EL-4, and other machines - been working great. Now, New machine RedHat Enterprise Linux 5 Same connection method, works great with RH-EL-4 (ie: Refer to my earlier multiple sessions email) But when connecting to RH-EL-5 - provided I do nothing with the keyboard it works perfectly. If however, if I type anything on the keyboard - 1 letter, or 10 to 20 letters... within seconds of typing something, CygwinX totally hangs for some period of time (10 to 20 seconds) - ie: Windows says it is not responding - then it refreshes - catches up on what I type, then goes away for 10 to 20 seconds... repeat for ever Does not matter if I open an Xterm and type ls, or open FireFox and type 'http://something' I suspect RH-EL-5 is provoking something in CygwinX - I do not know. The CygwinX is very new (I got a new computer 1 month ago and did a fresh install of cygwin) The relevant X11 versions are below (grepped from /etc/setup/install.db) Looking bash/cygwin window where I started the session, I do not see anything important etc - ie: timeout messages, just the 'normal bunch of warnings' same on all machines - including RHEL5 Any suggestions? -Duane. xorg-x11-base xorg-x11-base-6.8.99.901-1.tar.bz2 0 xorg-x11-bin xorg-x11-bin-6.8.99.901-1.tar.bz2 0 xorg-x11-bin-dlls xorg-x11-bin-dlls-6.8.99.901-1.tar.bz2 0 xorg-x11-bin-lndir xorg-x11-bin-lndir-6.8.99.901-1.tar.bz2 0 xorg-x11-devel xorg-x11-devel-6.8.99.901-1.tar.bz2 0 xorg-x11-etc xorg-x11-etc-6.8.99.901-1.tar.bz2 0 xorg-x11-f100 xorg-x11-f100-6.8.99.901-1.tar.bz2 0 xorg-x11-fcyr xorg-x11-fcyr-6.8.99.901-1.tar.bz2 0 xorg-x11-fenc xorg-x11-fenc-6.8.99.901-1.tar.bz2 0 xorg-x11-fnts xorg-x11-fnts-6.8.99.901-1.tar.bz2 0 xorg-x11-fscl xorg-x11-fscl-6.8.99.901-1.tar.bz2 0 xorg-x11-fsrv xorg-x11-fsrv-6.8.99.901-1.tar.bz2 0 xorg-x11-libs-data xorg-x11-libs-data-6.8.99.901-1.tar.bz2 0 xorg-x11-man-pages xorg-x11-man-pages-6.8.99.901-1.tar.bz2 0 xorg-x11-man-pages-html xorg-x11-man-pages-html-6.8.99.901-1.tar.bz2 0 xorg-x11-nest xorg-x11-nest-6.8.99.901-1.tar.bz2 0 xorg-x11-vfb xorg-x11-vfb-6.8.99.901-1.tar.bz2 0 xorg-x11-xwin xorg-x11-xwin-6.8.99.901-1.tar.bz2 0 xorg-x11-xwin-gl xorg-x11-xwin-gl-6.8.99.901-1.tar.bz2 0 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
