I suggest reading the Admin guide but to save you the immediate effort, the Admin guide states:
QUOTE:
To install the Linux Client
1. Launch your Web browser.
2. In the location box, type http:// followed by the server name and the GO-Global logon file.
For example, http://server/logon.html
3. Click the Native Linux Client link from the list of Linux clients.
4. Save the GO-Global package.
5. Launch the Linux console and become root (Super User).
6. Install the package using: rpm –Uvh. (For example, rpm –Uvh goglobal-xp.rpm )
If you're looking to install the GO-Global server software for Linux, you're posting to the wrong forum. In that case, refer to the
GO-Global for UNIX Admin guide at
