Subject: x2goclient not connecting after upgrade

Date: Mon, 26 Nov 2018 08:52:15 +0100

[Message part 1 (text/plain, inline)]

Package: x2goclient
Version: 4.1.2.1-3
x2goclient fails to connect to a working xgoserver, no matter the
server version.

The client machine is Archlinux 64, upgraded to the latest  version
(as of yesterday).

I have downloaded and compiled from git the x2goclient sourcecode, but
this compiled version don't work
either.

This is the log generated by x2goclient:

Hmm, looks like a bug in your client side libssh. Can you try to downgrade
it?

Subject: Re: [X2Go-Dev] Bug#1349: x2goclient not connecting after upgrade

I did a bit of testing today, and managed to set it running. I happen to
have a non-standard port declared as default for ssh connections in my
.ssh/config file, in the form:

Host *
Port NNNNN

at the end of the file, because I have the custom of setting my installed
servers apart from the default 22, to minimize attacks from port scanners.
And not all my remote machines are declared in the config file, so this
line takes care of the forgotten ones. If I comment out that line,
x2goclient works again, both connecting to the default port 22 or to a
non-standard port.

It didn't matter before if I was connecting to a standard setup in port 22,
or a custom one. It always choked at that line.

This line doesn't give problems in my ssh connections, though. Perhaps
there is a problem somewhere in the parsing of the ssh config file? Where
should I report that?

Thanks for taking your time in answering (and motivating me in digging more
on this... ;-) ). It was really a nuisance, i use x2go in a lot if machines.

I also triggered this bug. It looks like some problem with the parsing,
because ist is also triggered if the non-standard port is defined for
some totally unrelated host.
