You should certainly be able to install across the network. There are several options depending on what you already have set up.
If you've got an NFS server running, just mount that drive on the Octane and install as if from a local directory.
If you've got a web server running, you can put the .tardist file somewhere accessible to it and use
http://hostname/path/to/example.tardist as the source. If you've got multiple tardist files, you can unpack them (with tar xf example.tardist) all into one "dist" directory and then use
http://hostname/path/to/dist/ as the source. (Note that the forum software is automatically making those example URLs into links but they're not valid!!!)
Those are, IMHO, the two easiest options. There are several others, like TFTP, if you want. See the
"Software Installation and Licensing" book at your favourite techpubs mirror (
https://techpubs.jurassic.nl is run by forum member jan-jaap). (Those two ARE valid links!)
Any method should work in both the Software Manager GUI (enter the http:// URL as the source) or on the command line with inst. (See the -f option to the inst command to specify the source non-interactively, or option #1 in the interactive menu.)
