WebMO Support Forum

Hi,

We have acquired a new server and freshly installed g16 and WebMO 23. G16 is working fine from the command line. However when I create a test user in WebMO and submit a job, I get the following error:

Cannot execute /opt/gaussian/g16/g16: Permission denied

There permissions for g16 are all 755. Thoughts?

Assuming you followed WebMO's installation instructions for Gaussian 16
https://www.webmo.net/support/binaries_ ... gaussian16
or something similar, Gaussian executables can only be accessed by users who are a member of the gaussian group (see steps 2 and 6).

WebMO typically runs as user "webmo" or as the webserver user, eg, "apache". Look at the ownership of a file that has been created by WebMO, eg, the input file of a failed Gaussian job. Make the webmo/webserver user is also a member of the gaussian group so that it can access the Gaussian executables.
