As Martin said, gaussian requires that the access to g09 directory (in your case it's apparently /home/software/gaussian/g09/g09) is restricted to you. The simplest way to do it is to change the permissions: e.g. chmod -R 700 /home/software/gaussian/g09 which will restrict the access to the entire directory (recursively) only to you, as long as you're the owner of the directory.

If not, do first chown -R your_username:your_username /home/software/gaussian/g09 (you man need to be superuser to perform it).

Dear Liangzhen,

my wild guess is that you are permitting all the users to use Gaussian executables. According to the previous version of Gaussian:

"Making the Gaussian 03 directories world accessible (i.e. by all users) is a security problem, is prohibited by the license, and the program will now refuse to run if there is world access."

http://www.gaussian.com/g_misc/g03/g03_rel.htm

So you probably need to take care of the users/groups who can access the G09 executables - possibly by definition of new group. Maybe simply removing the executable permission to Others may be enough.

Hope this helps,

Martin

Hi Martin,

Thanks for your explanation. It helps. 

I tried to tar the  "/home/software/gaussian/g09" folder and copy the compressed file to my own folder "/home/liangzhen/software/" and unzip it, then I could have the g09 package copied to my own software folder. Therefore the g09 package in my own folder is only accessible to me. And I tried to run calculation using g09, it worked fine this time. 

And, also thanks a lot, Bartosz. I am not the owner of the original Gaussian 09 directory. Since I am not the systAdd your answerem administrator, therefore I cannot chmod -R or chown -R. The problem is, the g09 was installed to be used by our whole lab, so I may ask the administrator to chmod -R 700 the folder. Besides, I was told that if chmod -R 755 may also solve the problem, however, I am not sure about this. I will ask the administrator to change the permission to have a try. 

If anyone is still searching the easiest way is

chmod u+x *.exe

chmod u+x g09

Dear Devashish,

unfortunately your solution is not going to work in this case. The original problem stated by Liangzhen is that the files were "world accessible". Your suggestion would only give the user "executable permissions". Since the program was run by the OP, he already has the permissions to execute G09. The only workaround to avoid this kind of error is to tighten the permissions from world accessible as stated in the license.

Best regards,

Martin

Use this Worked for me...

chmod -R 700 /home/username/path_to_Gaussian/g09

*replace username & path_to_Gaussian accordingly.

The chmod command changes the permissions of the file/folder. The 700 means that the owner has full access, and no one else. The -r means to apply the rules recursively (through subfolders).

Thank You.

I'm having a similar problem to Elaprolu one

Dear Elaprolu and Bakary,

the critical error message is:

Search path GAUSS_EXEDIR is ""

: No such file or directory

That means "g09" command is looking in the directory "GAUSS_EXEDIR" which needs to be set as an environmental variable to the directory of your binaries, for example in bash:

GAUSS_EXEDIR="/home/user/path/to/gaussian/binaries/"

prior to running the g09 command.

Best,

Martin

Thank you Martin for your reply.

My problem was solved. I was setting the wrong path for GAUSS_SCRDIR.

I was directing as: GAUSS_SCRDIR=$WORKING_DIR/$PBS_JOBID

Now I'm using

GAUSS_SCRDIR=$WORKING_DIR

and it is working.

$WORKING_DIR being the working directory.

Best,

Ajay Khanna Sir,

My problem is solved through your way.

Thanks

Dear Ajay Khanna....

Your instructions works for me.....

I am also facing the same problem. I am trying to run g09 job in my own laptop (Linux OS). Unfortunately, My job gets terminated without any error message! I have followed the recommended answers, but can not get rid off the issue. The input and output files are attached herewith
