[X2Go-Dev] Bug#1222: Timeout of about 30s to start the x2go session

2017-10-04 Thread Bruno CAPELETO 
Package: 
Version: <4.1.0.0-0x2go1.2~git20170806.1410+9.heuler.1>

# uname -a
Linux mtcie1 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u1 (2017-06-18)
x86_64 GNU/Linux
# cat /etc/issue
Debian GNU/Linux 9 \n \l


When connecting to this x2go server - linux client and/or Windows client, I
tested both - the session takes about 30s to start.

I checked the /var/log/auth.log : the ssh connexion is pretty fast (1-2s)
I checked the x2go session.log : it is finished about 30s later

What happens during these 30s I do not understand. I have other
installations on Debian 8, this does not take so long.

[X2Go-Dev] Bug#1200: Bug#1200: Bug#1200: Environment variables not set

2017-09-05 Thread Bruno CAPELETO 
Found : in sshd_config, one must use the "UsePAM yes" directive

I do not really see the link with the locales, and on top of that that open
some security holes I guess.
For example, adding this instruction I had to add additional instructions
to forbid the password authentication.

Conclusions for the reported bugs :
1. locales are set properly
2. I do not have the LXDE error "no session for pid..." anylonger
3. single app mode seems to work for my software (no crash so far)
4. I could not test right now ; I guess that one is related to something
else...

The issue came from my home-made sshd_config file.

I still work it up and will give here the solution in a few minutes.

[X2Go-Dev] Bug#1200: Environment variables not set

2017-09-05 Thread Bruno CAPELETO 
Dear Mihai,

What good piece of news to start the day with !!!

So you do not see that "bug" on a fresh install. Unfortunately I see it,
and also on a fresh install. It is even worse : I see it on 3 fresh server
installs :
- Ubuntu 14.04.4 LTS (old installation)
- Debian GNU/Linux 8
- Debian GNU/Linux 9

So it seems that I do not install the same way as the others. Let me give
the details :
- installation in text mode (as these are remote servers)
- installation of LXDE *only* (tasksel : LXDE and ssh)
- installation of X2Go

On the 2 systems I could test locally (Debian 8 and Debian 9), the French
locales are set properly when the user starts a local X session (the menu
is in French).
However, on a remote X2Go session, the menu always appears in English (no
need to start the software).

Thanks for your help,
Bruno

2017-09-04 Thread Bruno CAPELETO 
People in Laurux's forum have reported this software works in single app
mode but on an Ubuntu server.

So it looks like this crash issue is related to the non-proper setting of
the locale on Debian server...

[X2Go-Dev] Bug#1200: Bug#1200: Bug#1200: Bug#1200: Environment variables not set

2017-08-10 Thread Bruno CAPELETO 
Ok bug no 2 (no session for pid) is identified :
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864402

Concerning bug 3. and single app mode : when launching xterm and doing
"echo $LANG" there is nothing.
So the variable is not set, even with my workaround for bug no 1.
What is the difference between the full LXDE session et single app mode :
is there an explanation somewhere ?

The issue is coma : "." in English and "," in French. So the MySQL requests
fail and crash the software. But that is not the issue we should focus on
in this mailing list.
The issue is that the environment variables are not set correctly : in a
local session it starts in French (as it should), but in the x2go session
in starts in English.

Yes, this is related to LXDE. But once more, only in combination with x2go
: on the local station I do not have this error when I start a LXDE session.
Because LXDE is so light, it is very well adapted for remote desktop ; so
it is definitely a first choice for a combination with x2go.

Sorry I should have said "after typing" : when I press enter, libreoffice
starts loading, and suddenly I am ejected from the x2go session.

Let's say 80% buggy :-)

I mixed it out : it was reported in LXDE mailing list. In my case it
happens only in combination with x2go (fresh install, without any nx mixup).

x2go full session : xterm then /usr/bin/libreoffice -> works
x2go single application mode /usr/bin/xterm -> got the xterm, but typing
/usr/bin/libreoffice closes the session

2017-08-10 Thread Bruno CAPELETO 
Yes I am sure my system is set up properly. By the way, keeping x2go apart,
everything is running well, including the software I would like to use via
x2go.

Now I updated with the x2go heuler section as you suggested :
4.1.0.0-0x2go1.2~git20170806.1410+9.heuler.1

The bugs 1,2,3 are all still there (I can not test the bug 4 as I have no
Windows environment next to me at the moment).

[X2Go-Dev] Bug#1200: Environment variables not set

2017-08-10 Thread Bruno CAPELETO 
Package: 
Version: <4.0.1.20-0x2go1+git20170412.1125+9.main.1>

# uname -a
Linux mtcie1 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u1 (2017-06-18)
x86_64 GNU/Linux



The below bugs are most probably related to each other, that's why I open
one case for all of them.

The issues are the following : I want to use the French software Laurux,
which is based on Gambas interpreter, via a x2go session running on a
Debian 9 server running LXDE (same issues seen on an Ubuntu server,
x2goserver version = 4.0.1.20-0~1125~ubuntu14.04.1)..

As a prerequisite, the software is installed on the server and runs well on
a local session.

1. Whatever the client (Windows or Linux 4.0.3.1-4), the local environment
variables are not set properly and the software - which needs French
localization - crashes. That could be "solved" the following way :
/etc/x2go/Xsession :

...
LANG=fr
LC_ALL=fr_FR.UTF-8
export LANG
export LC_ALL
...

That seems to be a revival of older bugs, but it is definitely still here.

2. At the start of a new session, one gets a windows with an error message
"No session for pid ..." ; that bug has already been reported several times
in x2go bug tracking and marked as solved. Actually it is not on my brand
new system.

3. The single application mode does not work with some of the applications,
including that Laurux / Gambas. For example it works with /usr/bin/leafpad,
but /usr/bin/libreoffice makes the x2go session crash.

4. The mouse double clic does not work in a x2go session, but only
- within the Gambas software (works well for example when launching an
application) and only
- when the x2go client is running in a Windows environment (no problem when
client in a Linux environment)

Many thanks in advance for any support,
Bruno
