printing

Hi, is there any documentation related to best practices about printing in x2go? I'll describe my scenario.

1) Linux :
- I print Ok from my linux client
2) Mac
- Impossible to show client printing pop-up
3) Windows
- some of them shows the client pop-up printers but when I print to my local printer it do nothing.
- some of them can't show

Very strange. My x2goserver is remote (on Amazon). The ports of course are open, if not linux wouldn't work.

Thanks!

Clientside Printing on Mac Osx 10.11

Hallo!
Are there any special requirements to use standard ssh for clientside
printing on Mac (OSx 10.11)? I have enabled remote login on the machine
(this works fine). But the x2go Client cannot connect to the ssh daemon?

Any ideas?
Kind Regards, Bernhard

SSH agent forwarding with X2Go client

Hi,

I know this has been asked long ago before but it seems there is still no SSH agent forwarding with X2Go client (I know it exists with PyHOCA but I prefer using X2Go client).

Is it planned ?
This would be a very interesting feature since I would prefer avoiding deploying my users private keys on their remote machine so that they can hop on other machines without password authentication (espacially with our gitlab server).

I know there is a way to workaround this with the SSH proxy feature but that doesn't work well with Windows and my users are running X2Go client under Windows.

Best regards.

Walid

Want to set the Display number in X2GO client

Hi,

 

I am new to x2go and for a testing I need to export the display of a centOS docker onto the x2go client.

However, I am facing the issue is the Display number in the x2go client is changing as we connect onto the docker host IP with the specified username and password.

So the DISPLAY variable set for the x2go server in the docker doesn’t match with that of the x2go client and hence, it is giving the error “Error: cannot open display:”.

Can someone suggest me what I am doing wrong here or if there is any way by which we can set the display number to a specified value for a certain user or if we can make use of some other tool.

 

Thanks & Regards,

Subho

x2go stopped working, how do I debug this?

We recently moved a server to a new network and x2go is not longer working. The x2go client crashes too quickly to view or copy the error messages that occur before it fails.

On the server side, I can see these messages in this in auth.log. I've replaced all possible identifying information (hopefully) with bash-style variable substituions (e.g. $USER). I apologize as this reduces clarity, but I don't want any identifiable details on record.

$DATE $TIME $HOSTNAME sshd[14538]: reverse mapping checking getaddrinfo for $INTERNET_PROVIDER [$INTERNET_PROVIDER_IP] failed - POSSIBLE BREAK-IN ATTEMPT!
$DATE $TIME $HOSTNAME sshd[14538]: Accepted publickey for $USER from $INTERNET_PROVIDER_IP port 49488 ssh2: RSA $A_RSA_KEY
$DATE $TIME $HOSTNAME sshd[14538]: pam_unix(sshd:session): session opened for user $USER by (uid=0)
$DATE $TIME $HOSTNAME systemd-logind[1544]: New session 10 of user $USER.
$DATE $TIME $HOSTNAME su[15451]: Successful su for $USER by root

$DATE $TIME $HOSTNAME su[15451]: pam_unix(su:session): session closed for user $USER
$DATE $TIME $HOSTNAME su[15468]: Successful su for $USER by root

$DATE 17:05:01 $HOSTNAME systemd-logind[1544]: Removed session 10.


I'm not really familiar with things like this, but it looks like it is repeatedly creating new sessions, and then these sessions are closed (for some reason). I don't understand form these messages.

On the client side, this is as much of the log as I can get before the program crashes. I haven't been able to locate the x2go client logfiles .

Thanks in advance if you're able to help.

X2go on a tablet - options?

I want to travel light and still be able to connect "back home" via x2go 
if something needs my attention.  I will be carrying an Android tablet, so 
it would be great if I could use that (along with an external mouse & 
keyboard).  I see several options, but no clear indication of which is 
best:

1. Android with the work-in-progress client
2. Get a dual-boot tablet (Android/Win 10) and use x2go under Windows 10
3. Dual-boot with Android & Linux and run x2go under Linux

I don't need sound or file sharing or printing, but I do need the setup to 
be reliable. Has anyone tried this?  Has it worked for you?

thanks,

fresh install - debian sid

Hi,

as I had some problems (all sessions were killed on logout instead of
pause and resume) with my years-old x2go-server I decided to purge
x2go*.

But: on debian SID 64 I cannot install x2go again.

The reason are dependancy problems with nxagent. Any hints?

Thank you in advance,

Frank

Sorry to bother you

Hello my dear,

I am Mrs. Lela Ding, the wife of late (Mr. Isaiah Abraham Ding), a politician and a businessman who was killed by Rebels in my country, Sudan in December 2012. After I lost my husband by the enemies because of the political crises in my country SUDAN, then after the funeral of my dear husband, my last born (Idris) was kidnapped by the same bad people, and he has not been found till now. So I found out that my life is in danger in that country, and then I have to run away from the country to the West African country called Nigeria, with my little daughter, Kate. The reason why I write you is for you to stand as the trustee to my late husband funds in the bank, so that the transfer can be done in your name, I will give you all the information that may be required.

This is because after my explanations to the bank, the Royal Bank of Scotland, London, they advised me to seek for a good foreign partner who will help me transfer the money and it will appear in your account due to my current conditions .Meanwhile, the money deposited by my husband with the Royal Bank of Scotland is ($8,300,000.00 USD) eight million three hundred thousand USD. So if I get a positive response from you, then I will give you the contact information of the Bank to get in touch with them and to transfer the money into your account on my behalf. In the meantime, I promise you 40% of the total fund for your assistance, while 60% will belong to me. I hope for a positive reply from you as soon as possible. Attached here is our family photo and the man was my late husband.

 

Sincerely,

Mrs. Lela Ding.

X2Go TCE problem

Hello list,

I use http://wiki.x2go.org/doku.php/wiki:advanced:tce:install as my guide to install X2Go TCE on:
- Linux Mint 17.3 MATE x86-64 as X2Go Server, and
- Debian 7.90 as PXE server
(both are VMWare VM).

Booting my thinclient I got boot menu:
X2Go Thin Client Environment
- Boot from local harddrive
- X2Go Thin Client
- memtest86+ (run memory test)
Press [Tab] to edit options

When I choose "X2Go Thin Client", it just only showing text mode login as below:

Debian GNU/Linux 7 x2gothinclient tty1

Do I possibly missed something in my config?

Cannot share a Windows folder

Hi. We have x2go running in our servers here, and sharing folders from 
windows have been working fine for me. One day --- perhaps after a few 
reboots --- it stopped working. From the x2go client I get no information. 
On the server I can only see this in /var/log/messages

/usr/bin/x2gomountdirs[41899]: WARNING: insertion of 
/cygdrive/C/Users/N213A~1.WER/MYX2GO~1 failed (already mounted?), not 
mounting

My ~/media/disk/_cygdrive_C_Users_XYZXYZXYZ/ is just empty.

Any thoughts? How can I debug this?

We do have another mount going, for the windows network shares at 
~/media/disk/_cygdrive_/h/, that eventually works. It does take some time 
to run and I would also like to know how to make it faster...

Thanks,
    ++nic
