How do I install one version of SeaDAS to be shared by multiple users?

If multiple users wish to use one primary SeaDAS installation, SeaDAS can be installed under one normal user account and shared by any number of users.

Do not install or run SeaDAS as the root user. Doing so is a security hazard and may also lead to functionality problems.

SeaDAS 4.9 has a new more secure and flexible mechanism for shared installs. For detailed instructions on setting up a shared installation with SeaDAS 4.9 or later see the Shared SeaDAS Installations webpage.

For SeaDAS versions earlier than 4.9, the user who has installed SeaDAS must make the full path to the SeaDAS installation directory readable and executable for other SeaDAS users. This user should then execute the following commands:

chmod -R a+rwx $SEADAS/data
chmod -R a+rwx $SEADAS/config

For security reasons, it is suggested to upgrade to SeaDAS 4.9. If this is not possible, a UNIX group identifier (GID) can be set up for certain user accounts, and permissions only be given to users within this group. These users should then follow the first two steps on the Shared SeaDAS Installations webpage in order to set up SeaDAS to run on their individual accounts.
