I'm working on a project where I need to retrieve the current machine's
ip addr as well as the router address from open transport. How can I
obtain these informations within RB itself or do i need to write a
plugin?

Please post the reply via email can I'm having problem reaching this
newsgroup from my site.

I don't know for the router address, but you can IP address with a
socket object (click on the button with a globe and drag it to the main
window). If you need to access Open Transport function, it would be
easier for you to access them via the shared libs rather than a plugin.
You can get Open Transport shared libs with other shared libs at
ftp://ftp.apple.com/developer/Tool_Chest/Interfaces-Libraries/Libraries/
SharedLibraries.hqx and since there are many OpenTransport shared libs,
you can see which function is in each of them with PEF Viewer (also
available somewhere in apple's ftp). For a toturial on how to use shared
libs, go to Christian Brunel's home page (I don't remember the url, but
many sites hae a link to it, including RB monthly and RB webring).
