Bug#407: Sometimes mounts will remain, even after a close of the session
by Dick Kniep 21 Jan '14

21 Jan '14

package: x2goserver version: 4.0.0.11-0~736~ubuntu12.04.1 Hi you nice people who maintain X2go. Sometimes a session is not ended cleanly and most of the time this does not matter everything is cleaned up and a new session can be started. However once in a while, one or more of the sshfs mounts to the local system remain active. This means that any subsequent attempt to logon fails, because it tries to mount and the mount already exists. Maybe the solution is as simple as adding remount to the mount statement. (I don't know if this breaks the initial mount....) Cheers, Dick Kniep

PulseAudio 4.0 in X2Go Client win32 4.0.2.x
by Michael DePaulo 21 Jan '14

21 Jan '14

TLDR: I want to know if I should include PulseAudio 4.0 in the win32 builds of X2Go Client 4.0.2.x. For testing, should I post a 4.0.1.2 build with PulseAudio 4.0, or post a HEAD build with it? Mike#1 recently announced that "we are close to bumping X2Go Client to a new release series (4.0.2.x)" https://lists.berlios.de/pipermail/x2go-dev/2014-January/006847.html I have managed to compile PulseAudio 4.0 (the latest) for win32. I also managed to compile 3.0. The builds are here: https://build.opensuse.org/project/show/home:mikedep333:branches:home:mkbos… Unfortunately, neither 3.0 nor 4.0 fixed the issue in bug 363 and described on this wiki page: http://wiki.x2go.org/doku.php/wiki:bugs:pulsetestmatrix In other words, we will still need to ship "interims" builds with PulseAudio 0.9.6 to fix that bug. I am hoping that this bug might be fixed in PulseAudio HEAD/master, but I am still trying to compile it. Even if it is fixed, that doesn't mean we will necessarily ship HEAD/master. I also am not aware of any x2goclient-relevant win32 improvements to PulseAudio since 1.1. So I want feedback if we should include PulseAudio 4.0 in X2Go Client 4.0.2.x. My gut feeling is "yes, because we should stay current with upstream." I also want to know if for the sake of testing, I should post a 4.0.1.2 build with PulseAudio 4.0, or post a HEAD build with it. I can do the former within 2 days, and the latter within 5 days or so. I have done a small amount of testing of 4.0; I haven't seen any regressions. -Mike#2

X2Go Client 4.0.2.x will require a patch in libssh 0.5.x
by Mike Gabriel 21 Jan '14

21 Jan '14

Hi all, we are close to bumping X2Go Client to a new release series (4.0.2.x). This new release branch will require two patches for libssh 0.5.x that distro maintainers should bring into their distributions before packaging the soon-to-appear release series 4.0.2.x of X2Go Client. For further reading, please look at the bug I have just filed against libssh 0.5.4-1 in Debian. Attached to this mail, you will find the two required patches in normal diff format. Furthermore, X2Go Client currently does not work with libssh 0.6.0. We will try making X2Go Client build and run with 0.6.x releases soon. Our goal is that the 4.0.2.x release series will work with 0.6.1 and later versions. light+love, Mike -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#404: Parts of the username are sanitized away in the session name.
by Klaus Ade Johnstad 20 Jan '14

20 Jan '14

Package: x2goserver Version: 4.0.1.12 I have a user that is unable to login to a Debian Wheezy server using xfce4. She is able to login with ssh and with nx, but not with x2go. Her username is «eaan», and this is what happens when she tries to run x2gostartagent: eaan@server:~$ x2gostartagent eaan is not authorized at /usr/lib/x2go/x2gosqlitewrapper.pl line 526. : /usr/lib/x2go/x2gosqlitewrapper insertsession 51 server en-51-1390073858 at /usr/lib/x2go/x2godbwrapper.pm line 320. Notize how her username «eaan» somehow is sanitized into «en» in the session name, the aa's are gone. -- Klaus Ade Johnstad klaus(a)linuxavdelingen.no Mobil:938 69 567 67E61D18B2C44F8A3DA35C6D849F9F5F 26FA477D

by Mike Gabriel 15 Jan '14

15 Jan '14

Hi all, the libssh upstream developers released libssh 0.6.0rc1 some days ago [1]. Here is the list of new features that we hopefully find time and man power to cincorporate into X2Go Client: Added new publicy key API. Added new userauth API. Added gssapi-mic userauth. ^^^^^^^^^^ -> Kerberos based logins Added new callback based server API. Added Elliptic Curve DSA (ECDSA) support (with OpenSSL). Added Elliptic Curve Diffie Hellman (ECDH) support. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -> finally ECDSA support Added improved logging system. Added SSH-agent forwarding. ^^^^^^^^^^^^^^^^^^^^ -> PyHoca-GUI already has this and it is cool!!! Added key-reexchange. Improved documentation. Fixed timeout handling.

replacing su calls in X2Go Server scripts with sudo (or ???)
by Mike Gabriel 14 Jan '14

14 Jan '14

Hi all, as those of you who have studied X2Go Server code probably have noticed, X2Go uses the su command quite intensively. The problem about su is that it invokes a subshell whenever it is called. Those subshells are quite difficult to handle without providing space for exploitation. As su is (in all cases) used to drop privileges from root to a normal user, my suggestion would be exchanging the su calls by sudo calls. (sudo -u <user> <command>). The advantage of sudo: it does not invoke a subshell. Feedback? Request for comments??? Any other approach thinkable??? Thanks, Mike -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#398: Automounter only mounts first partition of USB media (at least in certain cases)
by Stefan Baur 10 Jan '14

10 Jan '14

package: x2gousbmount severity: normal version: 1.1.0.2-0x2go2~git20131217.483+wheezy.heuler.1 Hi, I have a USB device with several partitions. It's being detected by the automounter and shows up under /media like so: ls -lah /media/USB2.0_Mobile_Disk/ total 16K drwxr-xr-x 5 root root 100 Jan 10 12:16 . drwxr-xr-x 4 root root 80 Jan 10 12:16 .. drwxr-xr-x 2 root root 40 Jan 10 12:16 sdb drwxr-xr-x 4 x2gothinclient root 16K Jan 1 1970 sdb1 drwxr-xr-x 2 root root 40 Jan 10 12:16 sdb2 As you can already see from the ownership tag, only sdb1 is actually mounted. file -s /dev/sdb1: /dev/sdb1: sticky x86 boot sector, mkdosfs boot message display, code offset 0x3c, OEM-ID " mkdosfs", sectors/cluster 16, root entries 512, Media descriptor 0xf8, sectors/FAT 208, heads 17, sectors 802816 (volumes > 32 MB) , serial number 0x90e07535, label: " ", FAT (16 bit) I have to admit that the content of sdb2 is a bit unusual - it's an ISO9660 filesystem like the one you usually find on a CD. file -s /dev/sdb2: /dev/sdb2: sticky # ISO 9660 CD-ROM filesystem data 'Debian wheezy 20131213-23:56 ' Still, it's perfectly possible to mount it manually: mount /dev/sdb2 /media/USB2.0_Mobile_Disk/sdb2: mount: block device /dev/sdb2 is write-protected, mounting read-only mount [...] /dev/sdb1 on /media/USB2.0_Mobile_Disk/sdb1 type vfat (ro,relatime,sync,uid=104,fmask=0022,dmask=0022,codepage=cp437,iocharset=utf8,shortname=mixed,uni_xlate,errors=remount-ro) /dev/sdb2 on /media/USB2.0_Mobile_Disk/sdb2 type iso9660 (ro,relatime) So this should be supported by the automounter as well. Note: I haven't tried what happens when you insert USB media with several "regulary formatted" (FAT, ext_, ...) partitions, so I don't know if the automounter is limited to mounting the first partition in general, or if it is simply confused by the fact that this particular USB medium contains an ISO9660-formatted partition. -Stefan
