Hi, as a fellow Linux virgin I went through a very similar experience with setting up Panantir. As Tony has said using a graphical FTP client (I use SmartFTP cos it's free) makes life sooooooo much easier with regard to changing properties (just check or uncheck a tickbox till the properites strings match)
In the end I changed ALL the files in /usr/local/bin so they were executable and writeable, probably dumb but hey I didn't really know what I was doing
As for the openobex files, I matched the properties to those given on Cushmans page.
Final result although spasmodic on connection (probably my bad???) is AWESOME. Persevere, it's well worth it.
Cheers, Sim
