list of ethernet adapters and mac addresses in Tcl

[nick1313]

Dear group,

What is the command to get the available network adapters and their mac addresses on a computer using Tcl or any other package.

Thanks for your help.

There is none.
You use a system specific kludge.
There is no direct hardware interface to get this info.
You can grab it from a system utility using regexp.
Excuse the slop but the regexp here is too unwieldy for
this site.

set nicids [exec /sbin/ifconfig]
foreach line [split $nicids "\n"] {
            if {[regexp "HW.*(\[A-Z0-9\]+:\[A-Z0-9\]+:\[A-Z0-9\]+:\[A-Z0-9\]+:\[A-Z0-9\]+:\[A-Z0-9\]+)" $line all out]} {
               puts "$line, address = $out"
            }
          }

Don't know about windows, and don't care.
