Bug#1012: Session reconnect doesn't work (x2gobroker)
by Miguel Quero 07 Sep '18

07 Sep '18

I can confirm this bug, but the problem is not with all x2gobroker, the resume problem become when you use ssh broker. In my setup, when client connect with --broker-url=https://XXXX.XXXX.XXXX:8080/plain/inifile, all work fine and resume is working. But when same clients connect with same credentials to the same broker with x2goclient --broker-url=ssh://XXXX.XXXX.XXXX/usr/bin/x2gobroker --broker-autologin, all work fine but resume is not working, all connection open a new session :S. I cant debug with ssh broker :(. Any ideas? -- Miguel Quero | One eSecurity | www.one-esecurity.com M: +34 608 36 17 05 Europe (Spain): +34 911 011 000 PGP: 0x34AA 050B D15C 7593 5671 3748 40C6 8E95 6C5A 40D3

Bug#1226: x2goclient for Mac OS immediately throws error regarding "PulseAudio verison number" then crashes
by Sean Hooten 26 May '18

26 May '18

Package: X2GoClient_latest_macosx_10_9 Version: 4.1.0.0 Steps taken to produce the bug: Ran x2goclient.app, immediately get error upon initialization. Exact error message: > Error fetching PulseAudio version number! Unexpected format encountered. Expected: I expected x2goclient to initialize normally without an error message. What actually happened: x2goclient shows me the regular user interface with the pop-up error message. After selecting "Okay" it crashes. This was not an issue before, seemingly began happening spontaneously. I have attempted to reboot my machine, and reinstalled x2goclient and XQuartz to no avail. I have attached the full bug report. I'm not sure why it is attempting to fetch a PulseAudio version number, this is not on my machine and I had not yet attempted to connect to my server before receiving the error. OS: Mac OS X 10.11.6 Thanks! Sean

Bug#1253: ssh broker : bad error feedback in interaction mode
by Walid MOGHRABI 15 May '18

15 May '18

package: x2gobroker-ssh version: 0.0.4.0-0~972~ubuntu16.04.1 priority: bug Using the ssh broker is great because it adds the ability for the x2goclient to interact with the auth mechanism such as PAM so that you get notified that you need to renew a password for example. This is great but it doesn't always work well. For example, the user don't get the reason why the access is denied. Here are different tests I made based on the following setup : x2gobroker in ssh mode with local PAM auth based on Samba Winbind/Kerberos. I tried both situations to compare : * with the x2goclient in broker-ssh mode * with a term rying to connect through SSH 1) Account set for password change with temporary password in Active Directory, user type wrong password (neither old or new one) * with x2goclient: get message "Access denied. Authentication that can continue: publickey,password,keyboard-interactive" * with term : "Your account has been locked. Please contact your System administrator. Password: " 2) Account set for password change with temporary password in Active Directory, user type good password * with x2goclient: get a new password form in order to type (and confirm) the new password. Reseting password works and you get logged in to the broker with the sessions list displayed. However, if you click on the "cancel" button, x2goclient freeze and must be killed, you're not sent back to the login form. On the other hand, if you change your password and then be logged in, clicking on the session slot fails because this is the old password that is relayed to the session slot and not the new one. When it fails, you get a new login form to enter your password again, if you type the new password there, it works. * with term: "Password: ******" "Password expired. You must change it now." "Enter new password: ******" "Enter it again: ******" If you cancel (ctrl+c), nothing happen and you get back to the prompt. If you enter the good old password, you're prompted to change it then you're logged in. If you enter the wrong password, your prompted to retry 2 times then you get this message "Your account has been locked. Please contact your System administrator" (this is our security policy, this is normal behaviour, 2 fauils then blocked for 10mn. 3) Account disabled in Active Directory * with x2goclient: get message "Access denied. Authentication that can continue: publickey,password,keyboard-interactive" * with term : "Your account has been locked. Please contact your System administrator. Password: " Would be great to fix the issues in 2) and would be great to retrieve the error message directly from PAM so that we get the reason.

Bug#1252: ssh broker : load balancing not working
by Walid MOGHRABI 15 May '18

15 May '18

package: x2gobroker-ssh version: 0.0.4.0-0~972~ubuntu16.04.1 priority: bug Hi, Tried using x2gobroker-ssh (0.0.4.0-0~972~ubuntu16.04.1) instead of classical http broker and finaly got it working but in ssh mode, load balancing on my server farm is not working, every session is redirected to the same server (the first one) while it is balanced correctly with the http broker on the same broker server. I would love to send logs but it seems this broker don't produce log files or I couldn't find a way to get them.

Bug#1276: VcXsrv windows xserver crashes when trying to resume a fullscreen session
by x2go＠0bl.net 29 Mar '18

29 Mar '18

I have the same problem even with a single monitor system. Environment: - x2goserver 4.1.0.0 (ArchLinux) - Client: Windows 10 Build 1709 - Desktop: xfce4 Steps to reproduce: - Open Windows client (4.1.1.1), start a new session with "Connect to local desktop" (resolution does not seem to matter, but I'm using windowed 1650x1010) - Click "Full access" - As soon as the "New session" window appears, x2goclient crashes. Older versions of both the client and server (tried different hardware/distros on the server also) exhibit the same issue. Backtrace from Dr. Mingw of the debug exe: vcxsrv.exe caused an Access Violation at location 000000006E34F608 in module MSVCR120.dll Reading from location 0000000006E04648.

Bug#1279: Idle connection crashes and is unable to resume
by Michael Schneider 28 Mar '18

28 Mar '18

Package: x2goserver Version: 4.1.0.0 I recently upgraded x2goserver for Ubuntu 16.04.1. The output of x2goversion is below x2golxdebindings: 1.0.2.4 x2gomatebindings: 0.0.1.5 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: 3.5.99.16 x2goserver-xsession: 4.1.0.0 After doing so now Idle sessions crash and are unable to resume. The `nxagent` process for the user begins eating up 100% CPU. When I log in I get a pulse audio error. If I suspend the session (close the client without logging out) then reopen it right away (with just a few minutes) I am able to successfully resume the session. However, if I leave the connection active but idle for sometimes 15 minutes sometimes a few hours, the connection terminates. The client displays an error about the connection being terminated. When I try to log back in. The client pops up an error about the remote proxy and won't let me connect. To reconnect I have to log in with putty and manually terminate the session using: $ x2goterminatesession <session_id> Below are excerpts from syslog and session.log *Syslog* Mar 27 14:23:39 myhost systemd[1]: Started Session 5372 of user <user>.

Hi, sorry for the late reply. I was on vacation last week. I solved it with the configuration change of Samba Server. Following parameters have been set in /etc/smb/smb.conf: template homedir = /home/%U winbind use default domain = yes the plus "+" in the username is just shortened and the real username has no plus in it. It is all about the "\" The error I got was not so clear, that it is a problem with the backslashes in the username. A hint in the client or elsewhere would be fine.

I do auth through PAM + Winbind/Kerberos to a real Active Directory (not a Samba domain master) and I don't have to add the domain prefix so my usernames are simply the login part. You'll need to configure Kerberos though to make this work but this is in a real AD scenario, not sure what to do with a Samba domain. Here is my smb.conf if it can help : [global] security = ads realm = <my AD domain> workgroup = <my AD short domain name> idmap uid = 10000-20000 idmap gid = 10000-20000 idmap config * :backend =rid idmap config * :base_rid = 0 winbind enum users = yes winbind enum groups = yes template homedir = /home/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes winbind refresh tickets = yes restrict anonymous = 2 domain master = no local master = no preferred master = no os level = 0 kerberos method = system keytab Regards, Walid Moghrabi TRAVAUX.COM BAT I - PARC CEZANNE 2 290 AVENUE GALILEE - CS 80403 13591 AIX EN PROVENCE CEDEX 3 ----- Mail original ----- De: "Joost Rohde" <j.rohde(a)bd8.nl> À: x2go-dev(a)lists.x2go.org Envoyé: Mardi 20 Mars 2018 11:22:40 Objet: Re: [X2Go-Dev] Effective username not correct in Session ID because of plus sign in user names (Windows AD / Samba4) On 20-03-18 11:04, Stefan Baur wrote: > Am 20.03.2018 um 10:56 schrieb Mihai Moldovan: >> There are also problems with backslashes and other characters in user names. >> >> They originate from a new sanitization feature in X2Go Server that >> drops characters not deemed suitable for a username. >> >> A plus sign might not be part of the allowed character set, which >> would explain this behavior. >> >> We've had such an discussion before and I'm still not completely sure >> what to do with it.

A backslash is the default winbind separator *, and a plus sign very common to use. I didn't see any other characters used (yet), but making it a config variable would indeed help for these rare cases and gives admins some flexibility.
