IRIX and Software

question about freeware.sgi.com downloading/installation

When using the old default Netscape browser on my Octane, I click on the 'install' icon, but everything is just printed within my browser instead of being installed. I checked, and I *do* have the below additions set-up already in my /var/netscape/.../mailcap file. Is there something else I need to do? Thanks for your help.
--------------------
To configure your browser to support auto-install (i.e. calling tardist or SoftwareManager automatically when you click on a .tardist file on the web) you should have two entries added to your mailcap file (either your personal ~/.mailcap or, depending on your browser version, the system one in /var/netscape/.../mailcap, /usr/local/.../mailcap, or equivalent).

application/x-install; \
/usr/sbin/SoftwareManager -a -F %s ; \

application/x-tardist; \
/usr/sbin/SoftwareManager -a -f %s ; \
description="SGI software distribution archive"

never ever do it this way. download the tardist, extract it with tar (it's just a tar anyway) and then point inst or swmgr to where you extracted it

You can do this if you have cURL installed:
