Launching of Sas Management Console in Unix

japsas100 — Tue, 31 Mar 2020 02:27:34 GMT

Dear All,

I am trying to open the smc from unix its throwing the below error:

Warning: No xauth data; using fake authentication data for X11 forwarding.
connect /tmp/.X11-unix/X0: Connection refused

I follow these steps:

export DISPLAY=:0
ssh -x myuser@app.myserver.com
cd /pub/sas/SASManagementConsole/9.4
./sasmc_console

I have clicked the 'enabled X11 forwarding' before opening the unix session

Can you try launching 'xclock' just to verify if the X11 connection works fine? Just type 'xclock' and hit enter. If the package is installed on your machine and all the X11 settings works fine it will launch a clock for you.

If the above works then try launching "/pub/sas/SASManagementConsole/9.4/sasmc" instead of "/pub/sas/SASManagementConsole/9.4/sasmc_console"

Do you have a X-Windows server running on your desktop? Without one, there's nothing to forward to.

@AnandVyas

Here is output of clock command

sis$ xclock
-bash: xclock: command not found

Yeah, it looks like you don't have the package installed. What client are you using to connect to the Unix Server? PuTTY/MobaXTerm/Or something else?

@AnandVyas

Thanks for the reply.

I am using Putty.

Re: Launching of Sas Management Console in Unix

AnandVyas — Tue, 31 Mar 2020 13:31:33 GMT

OK, In-case of PuTTY you would need an X-Server running as well like X-Ming. Which X server software client are you using?

Re: Launching of Sas Management Console in Unix

@AnandVyas

I have no clue which X server we are using. If you share steps I will check.

Re: Launching of Sas Management Console in Unix

I would suggest (If possible) try downloading the free version of MobaXterm (https://mobaxterm.mobatek.net/download.html). It has built-in X11 server and SFTP server. This link has steps on how to enable x11 for the session and connect to UNIX server. https://docs.computecanada.ca/wiki/Connecting_with_MobaXTerm/en

@AnandVyas

Do we need to download MobaXterm in window env?

Re: Launching of Sas Management Console in Unix

AnandVyas — Tue, 31 Mar 2020 13:45:38 GMT

Yes, its a client like PuTTY (with some added features into one)

Re: Launching of Sas Management Console in Unix

japsas100 — Tue, 31 Mar 2020 13:57:27 GMT

@AnandVyas

Yes, I have downloaded the MobaXterm. What is the next step?

A little information to provide you with a picture of what is needed:

in UNIX, a graphical interface based on the X protocol uses several components:

the application that needs a graphical interface
the X server; this is a program that provides communication with the screen, mouse, keyboard and other devices
a window manager that controls how the applications share the screen
a connection between all those parts

The difference between Windows and the X protocol is that X allows the parts to be located on different hosts, and communicating via network.

SAS Management Console is the application in this picture, your putty client and the SSH server on your Linux provide the connection (by tunneling the unencrypted X traffic through the encrypted SSH), but you still need the X server and window manager, and that is what applications like the CygWin X server, X-Manager or MobaXterm provide.

Connect to you server from which you were trying to launch SMC. Steps to connect here - https://docs.computecanada.ca/wiki/Connecting_with_MobaXTerm/en
Once In, launch SMC the way you did in the initial post.

Since, you haven't mentioned, If the X11 forwarding on your UNIX/Linux server is enabled or not. In-case it isn't you wont be able to launch SMC or any X-Windows enabled application.

You can verify it via two ways: 1) check the sshd_config file for value of parameter "X11Forwarding". It should be set to yes. This file is located under system path /etc/ssh.
2) Once successfully logged into server using MobaXterm you should see all green as below:

@AnandVyas

Thanks for the quick reply.

I have validated the below points.

1) check the sshd_config file for value of parameter "X11Forwarding". It should be set to yes. This file is located under system path /etc/ssh.

Ans: I can see sshd_config has X11Forwarding yes but ssh_config has X11Forwarding No

2) Once successfully logged into server using MobaXterm you should see all green as below:

Yes

When I entered the command xclock its still throwing the error.

is$ xclock
-bash: xclock: command not found

ssh_config on the server does not bother you, as it controls the client started on the server; you only use sshd by logging on.

xclock is a standard X app used to display a clock in graphic mode; it is not installed on your server, and not needed except for checking that a X protocol connection is present.

Once you have started your X Window server and after that made your connection with putty, you should be able to start SMC on the server and have it display on your desktop.

Re: Launching of Sas Management Console in Unix

AnandVyas — Tue, 31 Mar 2020 15:35:08 GMT

It’s because you don’t have the package installed on your UNIX server. It’s
just to test if the X11 is working fine.

Can you try to launch SMC now from the terminal?

Re: Launching of Sas Management Console in Unix

japsas100 — Tue, 31 Mar 2020 16:10:17 GMT

@Kurt_Bremser @AnandVyas

Still, I am not able to open smc. I follow the below steps.

I can see X server running before login to putty its showing (stop X server current display into 192.XXXX.XX(

I can see X server running is still running.

sis$ export DISPLAY=:0
sis$ echo $DISPLAY
:0

sis$ ssh -X sh@xxxxxxxxx.cx

password:XXXXXX

Warning: No xauth data; using fake authentication data for X11 forwarding.

sis$ cd /s01/sas/sashome/SASManagementConsole/9.3
sis$ ./sasmc
connect /tmp/.X11-unix/X0: Connection refused

Re: Launching of Sas Management Console in Unix

AnandVyas — Tue, 31 Mar 2020 16:15:08 GMT

After connecting to server via MobaXterm can you just run below commands?

sis$ cd /s01/sas/sashome/SASManagementConsole/9.3
sis$ ./sasmc

Re: Launching of Sas Management Console in Unix

Kurt_Bremser — Tue, 31 Mar 2020 16:22:53 GMT

When putty finds a local X server on start, and X11 forwarding is enabled, it will create the necessary environment on the server on its own. After logging on,

echo $DISPLAY

should reveal this. Just start smc, without any further settings.
