Hmm, this doesn´t work for me. If I invoke it via
inetd.conf:
sunrpc stream tcp nowait nobody /usr/local/bin/test.sh test.sh

test.sh:
#!/bin/bash
/usr/local/bin/getpeername >>/tmp/peer.ip
exit

only a \n is logged to the file (so permissions et al are ok ;-) ).

However, if I do
inetd.conf:
sunrpc stream tcp nowait nobody /usr/local/bin/getpeername getpeername

waldner@st:~$ telnet ka 111
Trying 4.3.2.1...
Connected to ka.
Escape character is '^]'.
1.2.3.4Connection closed by foreign host.

(IPs obfuscated)

What am I doing wrong?
