network finger

[Alfredo Tomasini]

HI,
  I am trying to use rthe network feature under my linux SLACKWARE 11 
and 12. I copied and pasted the finger
example I found in the manual

    BEGIN {
      NetService = "/inet/tcp/0/localhost/finger"
      print "name" |& NetService
      while ((NetService |& getline) > 0)
        print $0
      close(NetService)
    }

and I get all time this error

gawk: finger.awk:3: fatal: can't open two way socket 
`/inet/tcp/0/localhost/finger' for input/output (No such file or directory)

I use the same example a while back under solaris 2.7/2.8 and it works !

I also tried several variant

NetService = "/inet/tcp/0/192.168.1/finger"                      same result

NetService = "/inet/tcp/1200/localhost/finger"                  same

I searched on the web but I did not find anything useful.
Any help is welcome

Thanks
Alfredo
