I am working with SAS 9.3 and Linux Servers. I connect from PC SAS to Linux everyday using the above method but suddenly yesterday I am getting the message that "Cannot start remote process".

It asks for Username and Password but after that error message logs.

I am able to connect to Linux Test Server using the same method perfectly but something is wrong with Production.

Any help/suggestion is appreciated.

I would like to review the most recent Connect Server log.

Where can I find that log? I can share the SAS Log for which was generated with TRACE and ECHO on. Will this help ?

Hi,

have there been any changes made to the set up, such as changing location of the script files?

Are all SAS servers up and running on the prod machine/where its failing?

Could you please add the log file including the code you are submitting, resp. give some detail about

how you connect?

Run the program with options symbolgen; to see if we can get as much detail as possible (if you havent done so yet)

Thanks

Anja

@bahadur26,

>> Where can I find that log?
Usually in /<SASConfig>/Lev<X>/ConnectServer/Logs

>> I can share the SAS Log for which was generated with TRACE and ECHO on. Will this help ?
Nope, it's important to understand what kind of error you received on the server side.

Hi Anja,

There has been no changes in the servers or the script file location. I have checked all the files and unixauto.scr.

Checked both SAS Servers, they are up and I can work with them in Linux.

Following is the signon script:

%let mynode=epensass06 5005;
options netencryptalgorithm=sasproprietary;
options comamid=tcp remote=mynode;
options symbolgen;
filename rlink "C:\Users\c-absingh\Documents\unixauto.txt";
signon;

Following is the log for the session:

603 %let mynode=epensass06 5005;
604 options netencryptalgorithm=sasproprietary;
605 options comamid=tcp remote=mynode;
606 options symbolgen;
607 filename rlink "C:\Users\c-absingh\Documents\unixauto.txt";
608 signon;
NOTE: Remote signon to MYNODE commencing (SAS Release 9.04.01M3P062415).

Unixauto is attached if you want to have a look at it.

I have tried the command directly on Linux Command line and I am getting the mesage "Session Established" but white remote submitting, It says that CANNOT START THE REMOTE PROCESS.

Hope this would help in finding a solution.

Hi,

what port are you using? Has something changed there?

Can other users/clients connect to that server?

The error messages you are seeing usually indicate that the port is not open,

the user ID is not valid, or the script has been "relocated"/something has changed in the script.

This is not the case here as you mentioned, so I am curious if there are other users

experience the same problem?

To make sure you can resolve this quickly, contacting Tech Sup might be the best next step.

Am of course happy to continue working with you here, Tech Sup is just more troubleshooting savvy than I am 🙂

Thanks

Anja

All other users are facing the same issue. That's why I am thinking that there is something which is wrong on the server side or the port.
I contacted Tech Sup and they are working on it.

Perfect.

Maybe you could share the solution, I'd be interested what the problem is/was.

Best

Hi @bahadur26

Does your Machine/Desktop/Laptop has telnet?
Can you try to telnet <hostname> <port> and see if you are able to connect?

example: telnet sashost.example.com 7551

you can do this from command line on your machine.
Start -> All Programs -> Command Prompt.

Thanks,
AV

Re: SAS Connect Issue from PC SAS to Linux ?

bahadur26 — Wed, 14 Jun 2017 12:47:26 GMT

@AnandVyas I have already tried telnet Server port on command prompt but it is an unrecognized command on my system.

Re: SAS Connect Issue from PC SAS to Linux ?

AnandVyas — Wed, 14 Jun 2017 12:49:16 GMT

Hi @bahadur26

Okay, then telnet is not there on your machine. As you have mentioned that many users are facing the same issue, may be you can check if any one has telnet on their machine to test this approach.

Or else can take help from IT Support.

Thanks,
AV

Why are you calling bash instead of calling sas directly?

TRACE: Type 'bash /sas09/SASFoundation/9.3/sas -dmr -comamid tcp -device grlink -noterminal
-nosyntaxcheck' lf;

What happens if you just log onto the unix server yourself and issue that command? Do you get an error message? What if you remove the extraneous "bash" from the beginning of the command?

Re: SAS Connect Issue from PC SAS to Linux ?

bahadur26 — Wed, 14 Jun 2017 13:13:21 GMT

@Tom

When I login to Unix Server and issue the command, I get the message that "SESSION ESTABLISHED"
I have tried the same command with BASH, WITHOUT BASH and by CONNECT.BASH (Startup profile method).

Re: SAS Connect Issue from PC SAS to Linux ?

Tom — Wed, 14 Jun 2017 13:33:11 GMT

How long did it take to launch SAS when started from terminal? Perhaps 90 second time out is too short?

Also it looks like you are going down the Unix Spawner section of the signon script. Perhaps that means that your profile hasn't run or something else is different.

Perhaps you should create a script like the one in the comments of the script. Create a text file with something like this in it.

#!/bin/ksh
. ~/.profile
/sas09/SASFoundation/9.3/sas -dmr -comamid tcp -device grlink -noterminal -nosyntaxcheck

Set the execute bit on the file and than change the SAS signon script to call the new command you created instead of trying to call SAS directly.

@Tom

When I launch SAS from terminal, it takes less than 5 seconds to launch a session so I believe that 90 seconds timeout is sufficient.

I think when someone enters a right pair of username and password then it returns the Hello> and the control goes to Unix Spawner section.

I have tried saving the profile into a connect.bash file and then addressing the file rather then launching the SAS but the result is same.

Let me reiterate that I am able to launch a SAS session from PC SAS if I am connecting to Test Server but this error comes only if I am connecting to Prod.

If I change the server name in the signon script then everything goes smooth.

I am really not sure whats wrong here and I really appreciate your minute inspection and suggestion.

Thanks,

Abhishek

@AnandVyas I found below message using telnet at command prompt.

Find the picture. Error Message says that Access Denied for both Test and Production servers. But PC SAS is having issues only with Production server, Test server is running smoothly.

Re: SAS Connect Issue from PC SAS to Linux ?

Tom — Wed, 14 Jun 2017 19:07:02 GMT

I would have your systems team confirm that the two machines are actually similar. For example is SAS even on the production machine? Is it in the same place? Is SAS/Connect licensed on that machine? Installed? Are the search paths appropriate for SAS to work? etc.

If that doesn't work then open a ticket with SAS support. Ideally your local support group should know how to do this, but generally they do not know enough about how SAS works to debug all issues that can happen. SAS support should be able to ask the right questions to help you get it working.

Re: SAS Connect Issue from PC SAS to Linux ?

bahadur26 — Wed, 14 Jun 2017 19:17:00 GMT

@Tom

Everything is Yes.
Already opened a ticket with SAS Technical support, but moving at a very slow pace.
