Bug#1131: x2gosqlitewrapper - Session not opening when username starts with a number
by Frank Knoben 09 Jan '17

09 Jan '17

Package: x2gosqlitewrapper Version: 4.0.1.20-3.4 When a username starts with a number, the session on the client computer will not open, after connecting to the server. The problem lies within x2gosqlitewrapper.pl in the sanitizer function. This function will return 0 in the $type eq "x2gosid" case, when the username starts with a number. My workaround is to add a 0-9 in the line number 67 of x2gosqlitewrapper.pl diff x2gosqlitewrapper.pl x2gosqlitewrapper.pl.original 67c67 < if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { --- > if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { elsif ($type eq "x2gosid") { $string =~ s/[^a-zA-Z0-9\_\-\$\.\@]//g; if ($string =~ /^([a-zA-Z0-9\_\-\$\.\@]*)$/) { $string = $1; - if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { + if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { if ((length($1) > 0) and (length($1) < 48)){ return $string; } else {return 0;} } else {return 0;} } else {return 0;} } I am using a OpenSuSE Leap System with x2goserver Version 4.0.1.20-3.4 Sincerly Frank Knoben

Bug#1126: x2go session disconnects causing an issue with a program or caused by an issue with a program
by Ulrich Langenbach 04 Jan '17

04 Jan '17

Package: x2goclient Version: 4.0.5.2-0~1205~ubuntu14.04.1 severity: critical The session disconnects at some 'arbitrary' point in a way. Today I hit the issue whilest running the client in debug mode: x2goclient --debug and got this message (line 119 in the attached log): x2go-DEBUG-../src/onmainwindow.cpp:6014> Proxy wrote on stderr: "Error: Can't add a message of 4143380232 bytes to write buffer. Error: Assuming error handling data in context [B]. Session: Terminating session at 'Sun Dec 18 18:48:08 2016'. One of the instances of the program run within the remote session stopped working with an internal error. Sometimes the session crashes completely so that also the servers X session is gone, although that might be a different issue. I run an up-to-date Ubuntu 14.04.5 LTS (kernel 3.13.0-105-generic, libc 2.19-0ubuntu6.9) and X2Go Client 4.0.5.2 installed via http://ppa.launchpad.net/x2go/stable/ubuntu. This is really annoying, especially as this may ruin some hours of work and/or compute. The bug seems to be only triggered by one of our most used EDA tools, Vivado, especially in its version 2016.2. As this issue is probably complicated to reproduce, find and fix, a workaround is also very appreciated. Thank you very much! Ulrich

Bug#1130: Arctica-NX-Libs Betatest fails with Ubuntu 14.04
by Walid MOGHRABI 04 Jan '17

package: nx-libs Hi, following the instructions from http://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting, but using Ubuntu 14.04 and manually adding the MATE PPA for 14.04, I encountered the following error message as a popup from X2GoClient when trying to connect: "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." In /var/log/auth.log on the server, I get this error: Jan 4 15:54:39 test2 sshd[3431]: Accepted publickey for walid from 10.8.0.6 port 45976 ssh2: RSA 82:fd:9b:f0:24:b3:95:25:2e:c5:f1:85:ae:e5:8f:1a Jan 4 15:54:39 test2 sshd[3431]: pam_unix(sshd:session): session opened for user walid by (uid=0) Jan 4 15:54:39 test2 sshd[3431]: pam_systemd(sshd:session): Failed to create session: No such file or directory Jan 4 15:54:42 test2 sshd[3454]: error: connect_to localhost port 54731: failed.

Bug#1129: x2gobroker-ssh big delay in session status recovery
by Miguel Quero 20 Dec '16

20 Dec '16

Package: x2gobroker Version: 0.0.3.1 When x2gobroker-ssh is used with system with not IPv6 configured, this generate very big delays in x2gobroker listsession task. Before some research, the problem become from x2gobroker.utils portscan function. This function propagates a delay in all agents call because it tests first the IPV6 connection: /ip_proto = 0////try:////socket.getaddrinfo(addr, None, socket.AF_INET6)////ip_proto = 6////except socket.gaierror:////try:////socket.getaddrinfo(addr, None, socket.AF_INET)////ip_proto = 4////except socket.gaierror:////# we can't find a valid address for this host, so returning a failure...////return False /This will be fixed testing IPv4 first or more easily, setting a new option in config to select the ip protocol. Best regards. -- 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

The old behavior was to have one repository for every architecture, but that's not the "SUSE standard repository layout". Instead, SUSE uses one repository for all architectures. The information in the wiki is fine and already updated. If you take a close look at your last email/command output, you'll notice that the repository previously had x86_64 in the URL while it now doesn't. > Here are the result: > > zypper refresh > Retrieving repository 'perl modules (SLE_11_SP3)' metadata [done] > Building repository 'perl modules (SLE_11_SP3)' cache [done] > File '/repodata/repomd.xml' not found on medium > 'http://packages.x2go.org/sle/11.3/extras/x86_64' > > Abort, retry, ignore?

[a/r/i] (a): The key is not the problem, you obviously have it in your RPM DB already, as otherwise rpm would have given you a "NOKEY" error. Checking via "rpm -v --checksign" on the build server reveals: pwgen-2.06-90.3.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 9c6b0b2b: OK Header SHA1 digest: OK (693079e6da9cde1e9e5418c8a90d47ca4b89cf3a) V4 RSA/SHA1 Signature, key ID 9c6b0b2b: OK MD5 digest: OK (c680b2bf2f22c0f8e4e29a81efb326dc) I suspect (also from other resources I found on the net), that SLE 11.3 does not support V4 signatures, though. I have thus resigned only the pwgen package for now. Can you please retry installing x2goserver? It will definitely fail at some package again, but I want to see if pwgen now looks clean to your rpm binary (i.e., if it doesn't complain about it any longer.) If switching to V3 signatures with the SHA256 hash algorithm, I'll resign all packages on 11.3 and 11.2. Side note: please remember to include 1111(a)bugs.x2go.org when you're replying, so that your answer makes it into the bugreport. Mihai
