Hi, not sure if everyone is reading slashdot, so http://slashdot.org/stories/gateone might be worth a visit. This fellow coded a SSH terminal emulator in HTML5/JavaScript and is adding X11 support as well. -Stefan

Bug#337: nxcomp doesn't compile against libc++ STL
by Clemens Lang 05 Nov '13

05 Nov '13

Package: nx-libs Version: 3.5.0.21 The nx-libs-lite package does not compile on OS X Mavericks because Apple's clang compilers now default to compiling against the libc++ STL rather than (their outdated copy of) libstdc++. While the compiler still allows changing that, we should not rely on this being possible forever. The compiler chokes in Types.h, specifically the clear() methods in subclasses of vectors that use implementation details of the GNU STL. The attached patch fixes these compilation issues by not overriding the clear() method when compiling against libc++, since the libc++ headers seem to do essentially the same as the overriden method. HTH, -- Clemens Lang MacPorts Developer

Bug#323: 323 bug
by Eric Forgeot 01 Nov '13

01 Nov '13

Hello, I have this problem as well. version 4.0.1.1 for the client version 4.0.1.6 for the server on linuxmint 15. All packages coming from the ppa:x2go/stable I tried this: 1/ sudo rm -f /var/lib/x2go/x2go_sessions sudo x2godbadmin --createdb 2/ creating a new ssh user on the server, and trying to connect with this new one. x2go detected the /home/my_new_user folder was missing, and when I created it, x2go refused to connect any longer. 3/ editing / renaming ~/.ssh/known_hosts from the client side (according to http://john.wesorick.com/2011/11/issues-installing-x2go.html I also commented the "HostKey /etc/ssh/ssh_host_ecdsa_key" in my sshd_config on the server) none of them worked. I also renamed the ~/.x2go/ ~/.x2goclient/ folders in my home I can barely copy the output from the error window ( it hides itself too quickly and can't find a way to get it from elsewhere) : Starting session at 'Fri Nov 1 13:28:55 2013'. Info: Connecting to remote host 'localhost:31004'. Info: Connection to remote proxy 'localhost:31004' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Fri Nov 1 13:28:56 2013'. Session: Session terminated at 'Fri Nov 1 13:28:56 2013'. (I don't understand why it tries to connect to localhost) My log in ~/.x2go/S-mylogin-50-1383308923_stDLXDE_dp24/sessions says: Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. x2go worked perfectly before, I can't trace when it stopped working but it's probably after some package updates.

Bug#334: Don't allow users to override X2Go commands via ~/bin (or similar)
by Mike Gabriel 29 Oct '13

29 Oct '13

Package: x2goclient Severity: important In X2Go it is currently possible to replace every command in X2Go Server by a command of the same name in ~/bin. An attacker could use this to infiltrate X2Go Client with arbitrary data. IMHO, we should make sure, X2Go Client only uses system-wide paths when evoking commands on X2Go Servers. This, of course, will boycott installing X2Go Server into ~<user> space, but actually, I prefer a safe setup to such custom installation tweaks. Feedback?!?
