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.
