Some institutions maintain firewalls, which prevent Pathway Tools from connecting to the WWW server , which is hosting software patches. Because bugs that are reported in between major releases are fixed by issuing patches, it is important that the patches can be downloaded by Pathway Tools, to fix any problems.

These institutions tend to offer an alternate mechanism for WWW access, going through a proxy server. Pathway Tools can download patches through a proxy server, if configured correctly.

To activate proxy server access, the shell environment variable PROXY has to be set to point to the proxy server and port, prior to launching Pathway Tools. For UNIX, it is best to do this in one of the user’s shell init scripts such as .cshrc or .login. As an example, in csh syntax:

setenv PROXY

For bash, syntax:


For MSWindows, right-click on the “My Computer” icon (on the desktop), and choose “Properties”. In the window that opens click on the “Advanced” tab, then click on the “Environment Variables” button. In the opened window, under “System Variables” click the “New” button and enter the name and value for the PROXY environment variable.
