Success with Gaussian03

[Albert Strasheim]

Hello all,

Not sure if this should go to fedora-test-list instead, but here goes...

I have successfully managed to get Gaussian03 (commercial software for 
computation chemistry) going on FC2 test2.

Here's a quick HOWTO:

1. Extract the LI2-800N.taz file provided by Gaussian, Inc. to /opt/g03. 
This is the x86 binary distribution of Gaussian03.

2. Gaussian03 won't run if its files are world readable, so create a 
seperate group for Gaussian03 users:

/usr/sbin/groupadd -r g03
/usr/bin/gpasswd -a myuser g03

3. Set up the permissions on the Gaussian03 files:

chown -R root.g03 /opt/g03
chmod -R a+rX /opt/g03
chmod -R o-rwx /opt/g03

4. Set the SELinux security context for the Gaussian03 files:

chcon -t bin_t `find /opt/g03 -perm +111 -type f`

(Modified command from the comment in bug 120140. Is this right?)

Now Gaussian03 can be run by any user in the g03 group (provided he/she 
sets the g03root environment variable and sources the necessary file from 
/opt/g03/bsd).

Cheers,
