Bug#611: X2Go Client for Windows cannot create C:\Users\<username>\ssh\known_hosts file when the username has characters from languages other than the system locale
by George Trakatelis 06 Nov '14

06 Nov '14

Hi all, I remind you that bug #566 'X2Go Client for Windows cannot create C:\Users\<username>\ssh\known_hosts file when the username has non-English characters' was cloned to bug #611 'X2Go Client for Windows cannot create C:\Users\<username>\ssh\known_hosts file when the username has characters from languages other than the system locale' in an effort to find a global solution utilizing UTF-8 encoding. Imho, bug #611 cannot be resolved in the near future. I must ask Dmitry to re-state what his problem is. Is it an issue related to a. bug #566 as described above, b. bug #611 as described above, c. or something different? Please provide details. George

Bug#342: Exact circumstances
by Ulrich Sibiller 06 Nov '14

06 Nov '14

Wil, I am a bit unsure about your exact setup. Are you connecting from Ubuntu 12.04 to 12.04 or to another operating system? Can you still provoke this behaviour with the latest os updates for 12.04 (there have been some fixes in libxfixes, IIRC)? Does this happen with 14.04 or 14.10, too? Can you please disable "Show window contents on resize" and retry? Uli

Dear Dmitry, Setting Russian as the default language for non-Unicode programs showed that x2goclient-4.0.3.0-20141021-setup.exe behaves correctly with test user name фисвуа. [To change system locale, I followed the instructions in http://windows.microsoft.com/en-us/windows/change-system-locale#1TC=windows- 7] So please investigate for other causes for the misbehavior of x2goclient's current release on your system. One such a cause would be known_hosts being read-only. [@Mike#2: ssh_write_knownhost()'s return value should have been checked whether it's zero or SSH_ERROR and acted upon] As there are portions of x2goclient that depend on code that ignores system locale [such as getenv( "USERNAME" )], you'd be better off if you didn't use user names with non-Ascii characters for the time being.

Bug#611: X2Go Client for Windows cannot create C:\Users\<username>\ssh\known_hosts file when the username has characters from languages other than the system locale
by George Trakatelis 06 Nov '14

I just noticed that Dmitry replied only to me, so I copy his reply below: ========================================================== It's the #566 No-go if OS locale is Russian & path to `known_hosts' contains Russian/Cyrillic characters. OK if if OS locale is Russian & path to `known_hosts' contains only English characters. Frankly, I don't know if generic English/Latin characters belong to Russian/Cyrillic character set. Best regards, Dmitry Mikhailov. ========================================================== Afaik, the patch is applied to both the preview (pre01) and the current release (20141021) of X2Go Client for Windows 4.0.3.0, so it's rather unusual to observe different behavior from preview to release. In my system (Greek Windows 8.1) with a user name in Cyrillic (фисвуа) (fyi, I pressed a-b-c-d-e-f to get it) and Greek locale both versions exhibited the same erroneous behavior (that's why Mike#2 introduced bug #611). I'll try to set Russian as the main language of my system to see what happens (if I can find my way in Russian and succeed in getting back to Greek :) George > -----Original Message----- > From: Dmitry E.

Bug#664: Domain\User notation for fails due to missing quotation of "\"
by Thomas Wagner 06 Nov '14

06 Nov '14

Package: x2goserver Version 4.0.1.18 Hi folks, I'm using x2goserver on an openSUSE 13.1 which is a member in an AD-Domain. Thus is have usernames like "DOMAIN\USER". Logging in with SSH works fine but starting x2go fails. For some users I get errors like MYDOMAIN\student is not authorized at /usr/lib/x2go/x2gosqlitewrapper.pl line 527. : /usr/lib/x2go/x2gosqlitewrapper insertsession 60 cd-sim MYDOMAINstudent-60-1415280062 at /usr/lib64/x2go/x2godbwrapper.pm line 320. For other users it works. I tracked the problem down to line 525 in x2gosqlitewrapper.pl. The line is: $user =~ s/$realuser-[0-9]{2,}-[0-9]{10,}.*/$realuser/; $realuser is a string like "MYDOMAIN\student". This is what makes the regex fail since \s is a special escape sequence in perl. Also usernames with other special escape sequences like \k fail. best regards Thomas -- Dipl.-Ing.

Hi Uli, thanks once more for your patch fixing #585. As you are currently experimenting with X2Go / KDE Apps / rootless NX mode... Have you come across this issue? http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=342 Maybe you feel like taking a look at it? Generally speaking, I hope the X2Go project receives more contributions from your side!!! Looking forward to that! Thanks!

Bug#585: Fix
by Ulrich Sibiller 05 Nov '14

05 Nov '14

Without XFIXES the client calls GetSelectionOwner() before every paste operation and therefor always knows the current selection owner. With XFIXES some clients rely solely on the XFixesSelectSelectionInput/XFixesSelectionNotify mechanism. But they never receive any notifications because the nxagent does not register at the real X server to receive those notifications itself and so never gets anything to forward to the clients. A client assuming it will get informed about owner changes skips the GetSelectionOwner() call. So it never knows that the selection owner has changed and refers to what it thinks the current owner is (itself). Attached is a fix for this bug. nxagent calls XFixesSelectSelectionInput for all its selections (t.i. CLIPBOARD and PRIMARY, _not_ SECONDARY) now. It (still) does not check the return code but the original code registering only CLIPBOARD did neither... This is a complete patch generated by git format-patch after using (d)quilt as documented in the wiki. As I did not find any hints of what patch number to choose I took 207 to put it as close as possible to other clipboard related patches. Feel free to change that... Uli
