While your method should work if that file actually exists, you probably
want to use libudev for enumerating and getting device information from
sysfs. libudev will also enable you to get hotplug notification.
For your your reply.
The fact is:
1) my linux distro starts with eth1 not eth0. Strange. I know.
2) my question was, why simply 'cat' works but I cannot read it from fpc
usign Tfilestream or readlin(F, S);
Since I don't have time to invest in a portable solution, I am happy
already if it works on my particular xubuntu distro.
