Can we have some old rpms in the x2go.repo?
by Norman Gaywood 15 Mar '18

15 Mar '18

Last night after upgrading several Fedora 27 systems with the latest http://packages.x2go.org/fedora/$releasever/main/$basearch nxagent now segfaults sometimes on connection, sometimes when doing a move of the x2goclient screen. Problem is, I can't roll back to the previous version (to test) as the repo does not contain the older rpms? Would it be possible to have a version or two to be able to do a "dnf downgrade"?

Problems after upgrading to recent x2go-server and x2go client releases
by h i 15 Mar '18

15 Mar '18

Hello, I've been experiencing problems with opening applications and resizing my x2go client window after installing the newest version x2go-server. The issues occurs on Ubuntu 14.04 and 16.04. What happens now is that every time I maximize my x2go-client window, the images on screen rapidly flicker and won't stop until I minimize the screen. Also, each time I move the window, a quick flicker occurs across the screen. This never occurred before this new release. I have a few systems with the current x2go verison installed, here is the output: x2goversion x2goserver: 4.1.0.0 x2goserver-common: 4.1.0.0 x2goserver-extensions: 4.1.0.0 x2goserver-fmbindings: 4.1.0.0 x2goserver-printing: 4.1.0.0 x2goserver-x2goagent: 3.5.99.14 x2goserver-xsession: 4.1.0.0 We have another system running x2go server, but have yet to update it due to the problems we've experienced. Here is the output of the previous version we are running without the issues: x2goversion x2goagent: 3.5.0.33 x2goserver: 4.0.1.22 x2goserver-extensions: 4.0.1.22 x2goserver-xsession: 4.0.1.22 On the client side, I upgraded to the 4.1.1.1 from 4.1.0.0 and experienced some issues. I have to click on the outside/top-right edge of the session panel for the login session window to appear. Any thing closer to the middle, and it won't respond. I also get a pop-up message about the sound that I had not experienced with previous versions. Once logged into a session, the flickering resulting from moving/maximizing the window is much worse. Fortunately, I was able to revert back to x2go-client 4.1.0.0. However,is there a way to revert back to this previous version/configuration of x2goserver. Right now, it is has been a lot of flickering while to trying to do routine tasks with the current release. Any insight would be appreciated. Thanks. H.

Can't install X2goserver on Debian 9
by Nigra Truo 15 Mar '18

15 Mar '18

This is my main system, where I use X2goserver every day of the week and have done so for years, it worked really well for many years now. After doing the newest x2goserver update, several things broke and I can't install x2go anymore. So I decided to clean up any old install, purged everything. Purge complained that directories were not empty. Then, after I erased the directories, it complains that they are not there (apt is super annoying at times where you can't get it right, no matter how you try). Now I'm stuck, can't install or deinstall: When installing, I get: X2Go is configured to use a non-SQLite DB backend, leaving the database alone (who configure that? I definitely not. There should not be a piece of x2go configuration left on the system, the whole point of the purge) Then the installer fails, because it probably does not have any db to work with? --------------------------------------------------------------------------- Created symlink /etc/systemd/system/multi-user.target.wants/x2goserver.service → /lib/systemd/system/x2goserver.service.

x2go Windows Client: Strange Issue with Screen Update
by Michael Klemm 10 Mar '18

10 Mar '18

Dear x2go-user list, I'm having trouble with the x2go Windows client on one of my machines. It seems that it misses some screen updates (see the attached screen shot). The screen was made after a I typed "ls" a few times. After I reconnect the session, the screen is updated properly once and then subsequent updates are missing again. This is on Windows 10 Pro (version 1709) and x2go client 4.1.1.1 (nightly build 2017-11-14). The error also happens with the 4.1.0 client. The server is a CentOS 7.4 box with x2goserver-4.0.1.20-1.el7.x86_64, the desktop is KDE. The same client version works perfectly on another Windows machine, so I doubt that the server or KDE is the culprit. If someone could provide me with a hint how to debug this issue to create a bug report, I'd appreciate it. Thanks! Kind regards, -michael

x2go problems
by Steven Spencer 08 Mar '18

08 Mar '18

Greetings, We use x2go extensively for some access to some Ubuntu based LTSP servers. Suddenly over the last two days, we get the following in the client: "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." And on the server we are trying to connect to, we see this in the logs: /usr/bin/x2goresume-session: client [ip.address.of.client] has successfully resumed session with ID kscadmin-51-1520534328_stDMATE_dp24 /usr/bin/x2gosetkeyboard: /home/ksca0dmin/.x2go/C-kscadmin-51-1520534328_stDMATE_dp24/keyboard did not appear within 30s after agent startup We are never able to connect. This happens even on all servers that we connect to and includes older server versions: x2goagent: 3.5.0.33 x2goserver: 4.0.1.22 x2goserver-extensions: 4.0.1.22 x2goserver-xsession: 4.0.1.22 As well as newer ones: x2goserver: 4.1.0.0 x2goserver-common: 4.1.0.0 x2goserver-extensions: 4.1.0.0 x2goserver-fmbindings: 4.1.0.0 x2goserver-printing: 4.1.0.0 x2goserver-x2goagent: 3.5.99.14 x2goserver-xsession: 4.1.0.0 Unfortunately, the clients are now updated as well trying to fix this issue, but they were failing on the older client version as well: X2Go Client v. 4.1.1.1 (Qt - 4.8.7) Any help would be appreciated.

x2go server closes the inactive connection and not possible to connect again
by Pongrácz István 07 Mar '18

07 Mar '18

Hi, I use x2go successfully for several years and I very like it, thank you! I have a problem with the latest x2go (http://ppa.launchpad.net/x2go/st able/ubuntu xenial main). I can login without problem to the server, working as expected, but when I do not work on the x2go session (inactive or idle), the server closes the connection and it is not possible to connect again. Before the upgrade I had open sessions for days. Any idea? Below the technical details. The client debug shows (short version): x2go-DEBUG-../src/sshmasterconnection.cpp:2089> Forwarding parameters: from remote ("localhost":49454) to local ("localhost":49788) x2go-DEBUG-../src/sshmasterconnection.cpp:2126> Temporary session port after config file parse: 49454 x2go-DEBUG-../src/sshmasterconnection.cpp:2130> Temporary session host after config file parse: localhost x2go-DEBUG-../src/sshmasterconnection.cpp:2160> New channel forwarded. x2go-DEBUG-../src/sshmasterconnection.cpp:2320> "ssh_channel_write failed": "Remote channel is closed" x2go-DEBUG-../src/sshprocess.cpp:472> I/O error: "ssh_channel_write failed."" - Remote channel is closed" (2). x2go-DEBUG-../src/sshmasterconnection.cpp:2363> EOF sent. x2go-DEBUG-../src/sshmasterconnection.cpp:2367> Channel closed. x2go-DEBUG-../src/onmainwindow.cpp:6459> Proxy wrote on stderr: "Loop: PANIC!

Failure negotiating the session in stage '7'. Error: Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. Error: Wrong version or invalid session authentication cookie. So, on the server side the port 49454 did not exist and even on the server I can see the session running (with ps ax), it is not possible to connect (The remote NX proxy closed the connection....)) I did not find fresh or relevant information on the net, I spent about 2 days to figure out, but without success (purge, reinstall, xsession removing etc. - all done, without results) On the server, the sshd log contains this relevant information (it is the pair of the client debug log above): Mar 5 19:45:11 localhost sshd[19999]: Accepted publickey for xxxx from YYYYY.98 port 43002 ssh2: RSA SHA256:notrelevant Mar 5 19:45:11 localhost sshd[19999]: pam_unix(sshd:session): session opened for user username by (uid=0) Mar 5 19:45:11 localhost systemd-logind[787]: New session 9 of user username.

X2Go Client: Startup of VcXsrv sometimes fails
by Schmid Andreas 06 Mar '18

06 Mar '18

Hi, I'm running X2Go Client 4.1.0.0 on Windows Server 2012 R2 for connecting to X2Go Server 4.0.1.22 on Ubuntu 14.04. This usually works flawlessly. Since about 4 months ago, however, X2Go Client *sometimes* fails to fully establish the session. (Sometimes means that it happens quite unregularly; which makes it hard to reproduce. But when it happens, it can last from 5 minutes up to around 30 minutes until connections are successful again.) In these cases X2Go Client actually connects to the server, but the startup of VcXsrv fails, so X2Go Client subsequently terminates the connection. I attached the log output of VcXsrv below. I suspect that in the cases when the connection fails to fully establish, VcXsrv for some reason doesn't manage to find a free display number. Maybe this is due to the fact that on the Windows server several users are logged in simultaneously and use X2Go Client. Another guess is that VcXsrv might not like the fact that the Windows server has two IPv4 addresses. Does anyone have a clue what could be the reason for it? Or where I could find further information on these error messages? Thank you for any hint.

Fedora 27 and loginctl linger

It seems that 'loginctl linger' does not work anymore as an ordinary user on Fedora 27. This worked on Fedora 26. From: https://bugzilla.redhat.com/show_bug.cgi?id=1478974#c15 On Fedora 27 it seems that enable-linger does not work as an ordinary user which is required for x2goserver keep sessions alive. Inside an x2go session: $ loginctl enable-linger Failed to look up user 62: No such process and (as root) "loginctl show-user ngaywood" shows: Linger=no As root I can: loginctl enable-linger ngaywood and Linger will be set.

Attention: All X2Go Server Admins! Upcoming major X2Go (Server) Release
by Stefan Baur 23 Feb '18

23 Feb '18

Hi! We would like to inform you that a new X2Go stable version is about to be released, most likely around March 1st, 2018. In fact, the release is already ready - we are actively holding back the binary package builds at the moment so you have a chance to react. If you have set all your servers to automatically update to new releases, we suggest that you disable this mechanism now until you have verified that the new version works for you. If, on the other hand, you test and deploy updates manually, no change is required. Please test the new X2Go stable version as soon as it becomes available, so that we have a chance to fix any remaining issues that slipped through our testing early on. Should you encounter major problems with the new version, we suggest switching to the ESR branch, codenamed "saimaa". This branch will continue to receive security updates, but is (and will remain) based on what you currently know as "stable". Some packages, like cups-x2go, pinentry-x2go, x2godesktopsharing, x2go*bindings, are not part of saimaa and thus must be pulled from the regular repository. This requires proper setting of repository priorities, so packages existing in the saimaa repository take priority over packages from the regular repository. If you need assistance with this, please make sure you have disabled automatic updates before doing anything else, then ask for help either in our IRC channel #x2go on freenode, or on the x2go-user Mailing List. However, if you are a daredevil and already want to access binary packages that pretty much match what we are going to release soon, temporarily change your X2Go repository entry to the timestamped heuler repository bearing the timestamp of 2018-02-16, pull the update, then switch your repository back to stable. Note that this is a procedure not recommended for the average user. Try and use at your own risk.

When the Windows client display preferences are set to full screen (everything else default), the remote desktop session that appears on the client's physical display thinks it is connected to the "default" video output, for which xrandr (run in a terminal window, inside the remote desktop session) shows a maximum resolution of 1920x1200, with a resolution of 1280x720 selected, which is exactly half the width and half the height of the physical display on the client (2560x1440). The xdpyinfo command reports a dpi of 75. If I set the client preferences to 192 dpi (corresponding to physical display on client), the resulting remote desktop session is still 1280x720, but all elements are scaled up by a factor of 2. It is my understanding that this is the default scaling generated by X when it detects (or is given) a dpi larger than some value that it considers to be hi-dpi. I have seen suggestions about creating a new display section in xorg.conf on the server for a virtual monitor, but most people report that does not work. I am not knowledgeable enough to understand exactly how x2go interacts both with the X-server on the x2go server (RHEL 7.4) and with the X-server (VcXsrv) on the x2go client (Windows 10). I'm thinking that somehow, if possible, I need to change the "default" video output used by one or the other of those X-servers to allow 2560x1440 resolution. Does anyone know how to do this? Even if I get that to work, I may still have an issue getting the MATE desktop to use my desired hi-dpi scaling (instead of just forcing everything to double). Inside the remote MATE desktop, I am not able to change any display preferences; it always produces an error related to the versions of xrandr (display preferences requires at least 1.3, server version is 1.2, though program I'm actually running is 1.5). And would it be worth my time to try again building x2go from the Arctica project? Jean-Paul

Re: [X2Go-User] Fullscreen on multiple monitors
by Rob Janssen 14 Feb '18

14 Feb '18

Thanks for your reply! Well, maybe my terminology is wrong, but as I wrote I want to use Windows on the first physical screen and Linux via X2Go on the second physical screen, using the full screen so not running in a fullsized window. But that is all I can achieve now. Before, I could really use the full screen. It is a 1600x1200 screen and that was also the display size in X. Now the display size is less. Hope that is clear. Thanks for the hint w.r.t. the settings. I don't think it is a userfriendly solution, maybe I should file a bug report? It should just allow setting of options before it bombs out, I think. However, now that I have experimented with the settings and know it does not solve my issue, it is not an import problem at this time. BTW: I installed it on 64-bit Windows, so the program gets installed in Program Files (x86), but when I first try to do these settings the default X server path is in Program Files without the (x86) so that is obviously an invalid path. the default should be set to the actual location.

Fullscreen on multiple monitors
by Rob Janssen 13 Feb '18

13 Feb '18

I am using a setup where on a Windows PC I have the usual Windows interface on the left screen, and on the right screen I want fullscreen X2Go client. This has worked OK in the past on a Windows Vista PC with an X2Go version from 2014. For obvious reasons the PC has since been replaced and I have installed more recent X2Go software and from then on it fails to work like it did before. I have selected to use full screen on monitor 2 in the past, and it used the full display area, although it always started in a somewhat erratic way. It first opened a window on the second screen, then told the Linux system the display size had changed, then immediately changed it to full screen and sent another display size update. This sometimes confused the Linux window manager, resulting in funny window placement, but otherwise it worked OK. On the new system, first with Windows 7 and now with Windows 8, and with X2Go version 4.0.5.0 at first and now 4.1.0.0, I cannot get it to work anymore. No matter if I select the full screen mode or not, it always opens the Linux screen in a window, and on the left screen. I have to drag it to the right, and then click the "full screen window" widget, it then changes to nearly-full-screen (there are no window borders but there is a title bar with the usual widgets). I have experimented with the -multiwindows and -multimonitors flags as suggested in a bug tracking item, but without the desired result. I also experienced another bug while trying this: when the settings for the X server are invalid, the program bombs out with an alert that the settings are invalid and I need to check my configuration, but then it is no longer possible to change the configuration because the program won't stay running. Fortunately I had an image backup of the system made just before I started that experiment. Please advise what to do next... Rob

X font path is wrong
by A- Team 09 Feb '18

09 Feb '18

Hi all, we want to use x2go for a custom application that requires additional fonts. We installed the x2go-server on a CentOS 7 machine from EPEL repository and the x2go-client on Windows 7 (32-bit). When starting a session with xterm as application, that works as expected. But when starting a session with our custom application, it complains about not finding the fonts. We realized that in the x2go session, the font path as reported by "xset -q" is: Font Path: /usr/share/X11/fonts/misc/ But when opening a PuTTY session with X11 forwarding the font path as reported by "xset -q" is: Font Path: fonts/misc/,fonts/TTF/,fonts/OTF,fonts/Type1/,fonts/100dpi/,fonts/75dpi/,fonts/cyrillic/,fonts/Speedo/,fonts/terminus-font/,built-ins For the latter case, we used VcXsrv as X server on the Windows PC, and our custom application works. It seems that X11 forwarding in PuTTY uses the font directories of the X server on the Windows PC, but x2go uses the font path on the x2go-server (CentOS machine). How can we change this behaviour? Setting font path with e.g "xset fp+ fonts/100dpi/" returns: xset: bad font path element (#97), possible causes are: Directory does not exist or has wrong permissions Directory missing fonts.dir Incorrect font server address or syntax regards, Ralph

windows-10: how to setup borderless fullscreen window mode in multi monitor setup?
by Jörg Scheuermann 08 Feb '18

08 Feb '18

hey there, I have a new Windows-10 PC with 2 different-size monitors (16:9 + 4:3) attached. In my old Windows-7 PC I used to have X2Go running in borderless fullscreen window mode completely covering my widescreen monitor - so I could easily use the 4:3 monitor (e.g. Windows terminal program on the small monitor, while the X session covers the big one) without disturbing the 16:9 monitor. I tried that with my new Windows-10 PC to no avail - best I could get is Fullscreen mode, but this does not work for me: the mouse is locked to the big X screen and I cannot simply move to the small one. to do this I have to leave the fullscreen mode -- very distracting (flickering) and annoying. configuring the output to not be fullscreen but any of the other options does not get me to what I was used to have either: it's placing the X screen somewhere in the "middle", covering both of my monitors ... //update: seems when playing with output settings, x2go stores some strange settings somewhere - only way to get rid of placing the X screen "between" my monitors was to completely deleting that session and entering all the data again into a new one :/ anyway: I now have somethings I can live with, but still not perfect: even if I set the Display to "use whole monitor", it is not overlapping the taskbar - but only above! - meaning my X Desktop is higher than my monitor and I always have to scroll to see the top/bottom :-( --> is there any way to: * either have the X Window covering *everything*, including the taskbar, * or only let the X server render the screen not in the full height, but excluding the taskbars height? any of these options would get me the full X desktop on my widescreen monitor, without the need for scrolling; I don't really care whether I see the taskbar or not... any help please! p.s. the other two Display options are broken: * "custom resolution" does not take the selected monitor into account (see above: it's placing that custom window in the 'middle', covering both of my monitors) * "maximum size" does not generate a borderless window p.p.s. if I set the taskbar to auto-hide, the X screen still is pretending that it was there, i.e. it's not covering the taskbars space and I have an empty row where the taskbar used to be... /joerg

Upcoming Deprecation of (Almost) EOL Distributions
by Mihai Moldovan 07 Feb '18

07 Feb '18

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have (almost) reached End Of Life on December 31th 2017. This includes the following distro versions: - Debian: o 7.0 "wheezy" - Fedora o 23 o 24 o 25 - OpenSuSE o 13.1 o 13.2 o 42.1 Ubuntu builds are ceased automatically after upstream deprecation. After deprecation, no new builds will be published and existing builds will be moved to the archive repositories to discourage users from installing unmaintained software. Mihai

Gnome 3 and X2go

When gnome3 first came out I was unsuccessful at getting it to work with x2go. However, I just tried installing gnome-flashback and gave it another shot, now it mostly works except I can find no way of logging out except to kill the gnome-flashback process. Am I missing something that should be installed or is it broken this way? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

TCE usb mount
by Widu Wittekindt 29 Jan '18

29 Jan '18

Hi again, now that the netboot image builds just fine even on a stretch build host, I have another problem - well I've got a problem for every solution :-) My client doesn't mount usb media, with any of the images I made, regardless of the distribution (stretch or jessie) or the repo (code.x2go.org or LinuxHaus) or the build host (stretch or jessie). But the usb mount works with an image I got from a friend here in Freiburg - but this is a jessie image and one of my clients will not boot with a 3.16 kernel :-( Of course I think I did everything just as I should: 1. put the config as a script in the BUILDDIR 2. put the usb mount patch as a script in the BUILDDIR 3. put the build-script in the BUILDDIR 4. source the config 5. call the patch script 6. call the build script. What am I doing wrong? And theres a second question: Is it possible to output the sound on the x2go-server? cheers Widu

Can't get full screen on Raspberry PI
by Blake McBride 25 Jan '18

25 Jan '18

Hi, I have a Raspberry PI running their latest OS (9.1 Stretch) And I am running x2goclient 4.1.1.0 I can't seem to get full screen. If I set x2goclient and set it to Display Fullscreen, it starts up and works fine except that it is a window on my screen (having a head line with minimize, atc. buttons). Then when I exit, it changed the config to Custom 1920x1078. In fact I just noticed that if I select "Fullscreen" and then click "OK", when I go back in, it's changed to Custom 1920x1078. Same thing with Display Use whole display. Nothing I do will make "Fullscreen" stick. Not having any problems on my LinuxMint box. Thanks for any help! Blake McBride

Hi, When I run x2go client on windows 10, the icon pops up on the taskbar and the process is running, but the GUI window does not display. I tried uninstalling and reinstalling several times and also tried the suggestions at this link <https://askubuntu.com/questions/593046/x2go-client-not-showing-gui>, but the GUI still does not appear. I also tried changing my screen resolution in case the GUI window was being drawn offscreen, but the GUI still does not appear. How can I troubleshoot this further? Best, Gladia

qt5 application window not rendered
by Bernd Schubert 25 Jan '18

25 Jan '18

Hi all, somehow qt5 application windows are not rendered anymore. I think this came with the upgrade to ubuntu 17.10, but I'm not totally sure. My desktop is xfce and I only rarely run qt applications - I recently noticed that qgit is broken and then noticed that not a single qt5 programm works. Applications linked to qt4 seem to work fine. So when I run qt5 programs, it brings up window, but this just shows whatever was under that new window, but not the real not content. Outside of x2go it works fine, of course. I also just updated x2go to the unstable nightly (Version: 2:3.5.99.12-0~201801110901~ubuntu17.10.1), same result. Before updating to the nightly build, it complained about xkb errors when I started qt5 programs, right now nothing except a gtk2 warning comes up. Is there any way to trace what is going on? I'm rather clueless about X debugging. Thanks, Bernd

What are athe difference between connexions
by Alain Aupeix 19 Jan '18

19 Jan '18

Hi, I have made a maintenance tool to easily connect to distant or local computers with different products like vnc, x2go, ssh connections, ... For x2go connexion, I use this command line: cmd="x2goclient --thinclient --kbd-type=pc105/fr --autologin --link=lan --clipboard=both --close-disconnect --session="+trim(sUser)+"@"+trim(sMachine)+" &" To change the connection type, I first modify command in .x2goclient/sessions before connecting If I connect changing command to XFCE, it works directly If I connect changing to SHADOW, if works, but x2go ask me for : display :0 or display :50 , and also if I want complete access (what I want) If I choose 0, it works, and also with 50, but in this case, no shared display as with XFCE In .x2go folder, I have this files : S-alain-50-1516374453_stDXFCE_dp24 which is generated by XFCE connection S-alain-51-1516383729_stS1XSHADalainXSHADPP0_dp24 which is generated by local connectiondisplay :0 S-alain-51-1516383880_stS1XSHADalainXSHADPP50_dp24 which is generated by local connectiondisplay :50 What are the differences between XFCE and local :50 connections ? Is there a way with some parameters to launch directly x2go local session ? Another minor problem: When I open a session from my desktop (1280x1024) on a notepad which has a screen of 1440x900) with x11vnc, I apply a correction of the screen size (about 0.88 for this computer) to have a complete display of the server screen. Is there a way to do such thing with x2go ? I have found the .x2goclient/sizes. [mainwindow] size=@Size(1175 747) pos=@Point(94 113) maximized=false Can I change it in this file or is it better to change it in .x2goclient/sessions ? Thanks for this nice product.

Hi, I've recently been trying to use X2go to connect to a Rpi3 running the latest ubuntu mate 17.10 This seems to work when selecting xfce or a new session but doesn't work when trying to connect to the local desktop (which is already logged in) I even tried installing / running x2godesktopsharing on the server side then enabling shared desktop, but that didn't have any affect (I think that's only needed for different users normally) * client - Windows 10 / latest X2go client 4.1.0.0 * server - Rpi3 / Ubuntu Mate / latest x2goserver 4.0.1.22-0~1197~ubuntu17.10.1 It just seems to jump out with the following message on the client "The connection with the remote server was shut down. Please check the state of your network connection" * I was able to rule out the client as the problem by connecting from windows to a x64 gentoo vm / local desktop vm which worked fine on the local desktop setting (same version 4.0.1.22 server) * I also tried connecting from a linux client to the rpi but with same results * For the rpi as the server, this only seems to affect connections to the local desktop, connections using a new session in the drop down work okay Logs attached below any ideas on how to get this going? one difference I've spotted with a working setup is the message "state file for this session does not exist" in the server logs client log: NXPROXY - Version 3.5.0 Copyright (C) 2001, 2010 NoMachine.

X2Go login very slow
by martti pitkanen 19 Jan '18

Hi, I am using X2Go server on Ubuntu Mate, kernel 4.4.0-109 by client 4.1.0.0 X2Go login has become a couple of weeks ago very slow, "Status: connecting" takes 2-5 min to complete. I can connect to the same server from cmd line fast. Can anybody tell me how I can trace what is going on in the server during login pahse? I log in by using uid/pw, authentication against LDAP by using pam. -- --- Martti Pitkänen APLcomp Oy Mariankatu 17 00170 Helsinki Finland Tel +358 9 1357266 Mob +358 40 0602157 www.aplcomp.com Mail: P.O.BOX 126 00171 Helsinki Finland
