Can't connect to Ubuntu Desktop

Hi, I'd like to connect from a Windows 10 Box to an Ubuntu 22.04.5 Server. It does not work. Either a X2go windows appears for a few seconds and vanish afterwards, or a window appears saying "Something has gone wrong".

Cant resume sessions X2Go + PostgreSQL
by Jooris Mettler 06 Jan '25

06 Jan '25

Hi there, I have a severe issue with x2go. There are 4 Servers (ubuntu 20.04) and a single PostgresQL Database running in Docker on a 5th device. It all started after noticing that some users couldn´t resume sessions, this seemed to spread to all users over several months. Restarting the Server fixed the issue short term, but is not an option to do frequently. Some things I noticed: 1. the users ~/.x2go gets filled up with references to /tmp/.x2go-<user>/<session-id> and ofc /tmp gets populated accordingly. Once a Session is closed, everything persists there. Since /tmp will be cleaned on a restart, I would assume some job would also delete these old references going to nowhere, but it does not happen. 2. While I can click the "suspend" button on the client, the session will not change on the server. Even manually running x2gosuspend-session <session-id> on the server via e.g. ssh and checking the status via x2golistsessions returns |R| for the session in question. 3. when suspending a session, I would expect it to create a folder in ~/.cache/sessions/xfce4-session-<servername:number>. It does not. If I try to connect to a still running (server side, but from client side "suspended") session, it will either prompt a wrong credentials error or continue normally, except no window will ever show up. In x2goclient debug mode It will not whow the reappaering "searching proxy for window: <session-id>" but will simply stop after: "x2go-DEBUG-../src/sshmasterconnection.cpp:2065> Executing remote: "bash -l -c 'echo "X2GODATABEGIN:cb3d39c0-4759-419a-a1da-7c6681410a50"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2goresume-session <session-id> 800x600 lan nopack us auto 1 both no; echo "X2GODATAEND:cb3d39c0-4759-419a-a1da-7c6681410a50";'" x2go-DEBUG-../src/sshmasterconnection.cpp:2082> New exec channel created. x2go-DEBUG-../src/onmainwindow.cpp:10344> Resolved localhost. x2go-DEBUG-../src/onmainwindow.cpp:10372> Port already in use: 6002 x2go-DEBUG-../src/onmainwindow.cpp:10602> X.Org Server started on DISPLAY 2. x2go-DEBUG-../src/onmainwindow.cpp:10824> All helper servers for Windows are started." No window shows, I can not resume a session. I can run terminate and it will not show up anymore on the list on the client side or using x2golistsessions, but it will still be there in the database. 4. Having a look at the database, I can see thousands of entries. Most of those sessions dont exist anymore, no user can connect to them, they are not shown using x2golistsessions. I thought I could simply delete them like shown in the wiki (https://wiki.x2go.org/doku.php/wiki:advanced:multi-node:x2goserver-pgsql?s[…) but it does not work. Trying to delete any entry will always result in DELETE 0. I hope someone has an Idea or that this is helpful in any way to debug and improve x2go. Best, Jooris

Sunday, Dec 29th - Last X2Go and orca e.V. Sponsorship Drive for 2024
by Vorstand ORCA e.V. 28 Dec '24

28 Dec '24

Dear $ALL, We hope you had some happy, relaxing and peaceful holidays over the last few days. As a quick reminder, tomorrow would be a good time to help out X2Go (and orca e.V.) financially. While we have received some donations to the general X2Go donation pool, which we can reassign as needed, donations towards our event budget have stalled for the last 5 months or so - only one recent donation has since shown up. This budget is used to cover costs for having handouts/posters printed for our booths, as well as travel/accommodation costs for our volunteers. It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can reimburse our volunteers, who have been covering all the costs up-front our of their own pockets. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go and orca are usually tax deductible for German tax subjects. Until December 29th, non-recurring donations up to 100 Euro made on any Sunday during December 2024 will be matched by Betterplace with an additional 15%. This offer is only valid until a funding pool of 4 000 Euro is depleted (per Sunday). So the earlier you donate on these Sundays, the higher the chance that your donation will receive the bonus. As tomorrow is the last of those Sundays, we hope you are willing and able to chip in, so we can keep hosting and attending events like these. To donate towards X2Go's events (posters, handouts, travel, lodging, …), please use one of these links: * English-language donation form: <https://www.betterplace.org/en/projects/131360?wirwunder=235> * German-language donation form: <https://www.betterplace.org/de/projects/131360?wirwunder=235> Further donation links (infrastructure, X2Go in general, orca e.V.) can be found right at the very top of the X2Go Wiki: <https://wiki.x2go.org/> If times are rough for you and you can't afford to donate, don't feel bad! You can also help us by forwarding this announcement to whomever you seem fit - e.g. your local Linux user group, your social media followers, etc. Another way to help us is to be vocal about what you need X2Go for and how it would hurt you if it would no longer be available - we're trying to apply for public funding, so if you're using X2Go in the public sector (i.e. education, research, health care, energy, industry), please do let us know how X2Go ceasing to exist would affect you. Kind Regards, Stefan Baur, first chairman of the board, Open Remote Computing Association - orca e.V.

Browser jerks

Hello! Some time ago after years of use I largely replaced x2go with LTSP because surfing in the browser was no longer practical. It jerked so much that we couldn't work with it. Is there a real solution for this now? Greeting, Olaf

x2go Windows client crashes with Putty Pageant with long RSA 4096 keys
by Gerhard Wiesinger 20 Dec '24

20 Dec '24

Hello, I'm having a crash problem with latest version (also previous ones) with ssh private key authentication and Putty Pageant. Looks like there is a buffer overflow involved. With several smaller keys (e.g. ssh-ed25519) it works well. I found a scenario to reproduce it: 1. Generate a RSA 4096 Bit length private/public key pair 2. Load it on the Windows client into Putty Pageant 3. Put public key at the server at ~/.ssh/authorized_keys 4. open connection to the server => crash, see logs Looks like it is a bug in the old libssh library version with large private/public keys. Can you please fix the topic. Some questions: - Is the used libssh version really version 0.9.2? - The logs have some entries with: agent_talk - len of request - That has been changed in git to another logging in 2011: https://git.libssh.org/projects/libssh.git/commit/?id=ba4f10dc4657952ec47f7… - Version 0.9.2 has been released in 2019: https://www.libssh.org/2019/11/07/libssh-0-9-2/ - So it looks, not the version 0.9.2 is used - Any plans to upgrade to latest version of libssh 0.11.0 while keeping Putty Pageant Agent support? - Upgrade plans to newer Putty version? - Is there a newer nightly Windows build from newer git sources available? Version: - X2Go Client 4.1.2.3-ba65703-kdrclient-a3134d6 - according to the logs: ssh_connect: libssh 0.9.2 (c) 2003-2019 Aris Adamantiadis, Andreas Schneider and libssh contributors. Distributed under the LGPL, please refer to COPYING file for information about your rights, using threading threads_pthread - Server: (not relevant but version is: x2goserver-4.1.0.6-4.fc41.x86_64) Thnx.

x2gomountdirs fails on Debian Stable (x2goclient 4.1.2.2)
by edv＠dgb-bwt.de 17 Dec '24

17 Dec '24

Dear All, first of all: great software, we (a small educational organisation for trade union members) have been working with it for years. TL;DR: shared folders do not work, when I use the GUI to mount a share directory ~/media/disk/SHARE-NAME remains empty. Our Setup: * x2goserver on a computer behind a rounter with portforwarding and dyndns * x2goclient on a computer behind another router * both debian stable The connection from x2goclient to x2goserver works (I mean: I get my remote desktop and work there), but when I want to use/mount a shared folder, nothing happens. I mean: If I want to access a folder on the x2goclient via the x2go function “shared folders” from the x2goserver, the directory ~/media/disk/SHARE-NAME remains empty. When I trigger the release in the GUI of x2goclient, the logs say: on x2goclient ----------- Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: insertion of shared folder into session DB has been successful Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: SSH key file has arrived: /home/serveruser/.x2go/ssh/key.cicFLi Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: SSH host key has arrived: /home/serveruser/.x2go/ssh/key.cicFLi.ident Nov 06 00:00:02 x2go /usr/bin/x2gomountdirs[295124]: executing: timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident "clientuser"@127.0.0.1:"/home/clientuser/Desktop" "/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop" -p 53200 Nov 06 00:00:03 x2go /usr/bin/x2gomountdirs[295124]: WARNING: mounting of /home/clientuser/Desktop failed ----------- on x2goserver ----------- Nov 06 00:00:02 kweezy sshd[244865]: error: kex_exchange_identification: Connection closed by remote host Nov 06 00:00:02 kweezy sshd[244865]: Connection closed by 127.0.0.1 port 52856 Nov 06 00:00:03 kweezy sshd[244871]: Failed password for clientuser from 127.0.0.1 port 52872 ssh2 Nov 06 00:00:03 kweezy sshd[244871]: Failed password for clientuser from 127.0.0.1 port 52872 ssh2 Nov 06 00:00:03 kweezy sshd[244871]: Connection closed by authenticating user clientuser 127.0.0.1 port 52872 [preauth] ----------- Terminal-Output of 'x2goclient --debug --libssh-debug' on x2goclient ----------- x2go-DEBUG-../src/sshmasterconnection.cpp:2121> EOF on channel 0x7f7ed4064930; SshProcess object: 4 x2go-DEBUG-../src/sshmasterconnection.cpp:2222> EOF sent. x2go-DEBUG-../src/sshmasterconnection.cpp:2224> Channel closed. x2go-DEBUG-../src/sshmasterconnection.cpp:2165> EOF on channel 0x7f7ed40586c0; SshProcess object: 17 x2go-DEBUG-../src/sshmasterconnection.cpp:2222> EOF sent. x2go-DEBUG-../src/sshmasterconnection.cpp:2224> Channel closed. x2go-DEBUG-../src/sshprocess.cpp:532> SSH finished: raw output (stdout): "X2GODATABEGIN:d396bc9c-fce4-420a-9c3a-b405fddfc022\ndirs:/home/clientuser/Desktop__REVERSESSH_PORT__53200\nssh port:53200\nHost:127.0.0.1\nUser:clientuser\ninserted, timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident \"clientuser\"@127.0.0.1:\"/home/clientuser/Desktop\" \"/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop\" -p 53200\nX2GODATAEND:d396bc9c-fce4-420a-9c3a-b405fddfc022\n" x2go-DEBUG-../src/sshprocess.cpp:543> SSH finished: true - "dirs:/home/clientuser/Desktop__REVERSESSH_PORT__53200\nssh port:53200\nHost:127.0.0.1\nUser:clientuser\ninserted, timeout 30 sshfs -o modules=iconv,from_code=UTF-8,to_code=UTF-8 -o idmap=user,uid=`id -u`,gid=`id -g`,default_permissions,ServerAliveInterval=300,IdentityFile=/home/serveruser/.x2go/ssh/key.cicFLi,UserKnownHostsFile=/home/serveruser/.x2go/ssh/key.cicFLi.ident \"clientuser\"@127.0.0.1:\"/home/clientuser/Desktop\" \"/tmp/.x2go-serveruser/media/disk/_home_clientuser_Desktop\" -p 53200\n" (17). x2go-DEBUG-../src/onmainwindow.cpp:8895> Post-cleanup for startX2goMount triggered. x2go-DEBUG-../src/onmainwindow.cpp:8920> Deactivating public key from "/home/clientuser/.x2go/ssh/gen/key.cicFLi.pub" again. ----------- I then tried to reach the client from the x2goserver via SSH through the SSH tunnel that was set up: ----------- serveruser@x2goserver:~$ ssh clientuser(a)127.0.0.1 -p 53200 -i /home/serveruser/.x2go/ssh/key.cicFLi Warning: Identity file /home/serveruser/.x2go/ssh/key.WEIIYY not accessible: No such file or directory. clientuser(a)127.0.0.1's password: ----------- This generates a message in the x2goclient log -- so the tunnel back to the client has been set up, but the temporary SSH key is no longer available.

X2Go: The Spread 2024 recordings online/X2Go and orca e.V. Sponsorship Drive
by Vorstand ORCA e.V. 14 Dec '24

14 Dec '24

Dear $ALL, Some of you might have missed it, as it wasn't announced on the mailing lists, only on the Wiki, due to massive time constraints/understaffing, but - we did indeed have an X2Go: The Spread 2024 virtual event. Which makes 2024 the first, and probably the only year where we had both an in-person/hybrid "X2Go: The Gathering" and a virtual "X2Go: The Spread" event. You can read up about what you've missed on <https://wiki.x2go.org/doku.php/events:x2go-spread-2024>, where you will find links to recordings of each day (save for Thursday - that was a live debugging session, so we didn't bother recording it). Here's a quick overview of the presentations/discussions: Monday * X2Go's State of the Union, Part 2 (Part 1 was presented at X2Go: The Gathering 2024) * X2Go's Funding Situation, Part 1: Sovereign Tech Fund Tuesday * Demo: Portable DHCP proxy with X2Go-TCE-live Netboot (a follow-up to X2Go: The Spread 2023's Thursday presentation) * Progress Report re: KDrive on arm64 * OSUOSL Behind-The-Scenes Update Wednesday * X2Go's Funding Situation, Part 2: orca/Betterplace * Gitlab Status Report Thursday * KDrive debugging Friday * Secure Remote Access Even to Old Windows XP Systems - Thanks to X2Go and a Raspberry Pi * NX-libs update * “Mr. Eyebot V2.0” - Quick Explanation and Demo Or, if you want to watch all recordings back to back, head straight over to YouTube, where we have prepared a playlist for you: <https://youtube.com/playlist?list=PLWDo4PkY3E0My_exV1bT7z5vOA63P5mqN&featur…> If you like what we're doing, now would be a good time to help us out financially. While we have received some donations to the general X2Go donation pool, which we can reassign as needed, donations towards our event budget have stalled for the last 5 months or so. This budget is used to cover costs for having handouts/posters printed for our booths, as well as travel/accommodation costs for our volunteers. It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can reimburse our volunteers, who have been covering all the costs up-front our of their own pockets. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go and orca are usually tax deductible for German tax subjects. Until December 29th, non-recurring donations up to 100 Euro made on any Sunday during December 2024 will be matched by Betterplace with an additional 15%. This offer is only valid until a funding pool of 4 000 Euro is depleted (per Sunday). So the earlier you donate on these Sundays, the higher the chance that your donation will receive the bonus. As tomorrow is one of those Sundays, we hope you are willing and able to chip in, so we can keep hosting and attending events like these. To donate towards X2Go's events (posters, handouts, travel, lodging, …), please use one of these links: * English-language donation form: <https://www.betterplace.org/en/projects/131360?wirwunder=235> * German-language donation form: <https://www.betterplace.org/de/projects/131360?wirwunder=235> Further donation links (infrastructure, X2Go in general, orca e.V.) can be found right at the very top of the X2Go Wiki: <https://wiki.x2go.org/> If times are rough for you and you can't afford to donate, don't feel bad! You can also help us by forwarding this announcement to whomever you seem fit - e.g. your local Linux user group, your social media followers, etc. Another way to help us is to be vocal about what you need X2Go for and how it would hurt you if it would no longer be available - we're trying to apply for public funding, so if you're using X2Go in the public sector (i.e. education, research, health care, energy, industry), please do let us know how X2Go ceasing to exist would affect you. Kind Regards, Stefan Baur, first chairman of the board, Open Remote Computing Association - orca e.V.

Dear $ALL, This is just a quick reminder that there will be another X2Go and orca e.V. sponsorship drive tomorrow, starting at 09:00 CET. We are still in need of almost 300 EUR to cover this year's hosting costs, and we're a good 2 100 EUR short in the "events" category, covering costs relating having handouts/posters printed for our booths, and travel/accommodation costs for our volunteers. Non-recurring donations up to 100 Euro made on Friday, 2024-12-06 (starting 09:00 CET and ending 23:59 CET) will be matched 100% by the Commercial and Savings Bank Ulm. This offer is only valid until a funding pool of 10 000 Euro is depleted. So the earlier you donate (past 09:00 CET) on this particular day, the higher the chance that your donation will receive the bonus. The donation links can be found right at the very top of the X2Go Wiki: <https://wiki.x2go.org/> To donate towards X2Go's events (posters, handouts, travel, lodging, …), please use one of these: * English-language donation form: <https://www.betterplace.org/en/projects/131360?wirwunder=235> * German-language donation form: <https://www.betterplace.org/de/projects/131360?wirwunder=235> To donate towards X2Go's infrastructure (hosting costs and the like), please use one of these: * English-language donation form: <https://www.betterplace.org/en/projects/131358?wirwunder=235> * German-language donation form: <https://www.betterplace.org/de/projects/131358?wirwunder=235> If times are rough for you and you can't afford to donate, don't feel bad!

Upcoming X2Go and orca e.V. Sponsorship Drives - Starting Tomorrow, 2024-12-01
by Vorstand ORCA e.V. 30 Nov '24

30 Nov '24

Dear $ALL, As we're approaching the end of the year, we can't help but notice that X2Go is running low on funds. We are still in need of almost 300 EUR to cover this year's hosting costs, and we're a good 2 100 EUR short in the "events" category, covering costs relating having handouts/posters printed for our booths, and travel/accommodation costs for our volunteers. It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can keep advocating for X2Go and free remote desktop/remote application projects in general, but also to keep our servers running. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go and orca are usually tax deductible for German tax subjects. There are two sponsorship drives coming up, the first of them starting tomorrow: 1) Non-recurring donations up to 100 Euro made on any Sunday during December 2024 will be matched by Betterplace with an additional 15%. This offer is only valid until a funding pool of 4 000 Euro is depleted (per Sunday). So the earlier you donate on these Sundays, the higher the chance that your donation will receive the bonus. 2) Non-recurring donations up to 100 Euro made on Friday, 2024-12-06 (starting 09:00 CET and ending 23:59 CET) will be matched 100% by the Commercial and Savings Bank Ulm.
