Is there an echo server I can use to test my programs?

I'm writing a simple client to ping a server with a packet on port 7 (echo) and then waiting for a reply. Is there a server that I can use to test this?

  1. sudo nc -vvlp 7 -e /bin/cat

    If you happen to have a inetd installed, most of them have echo built-in. Snippet from /etc/inetd.conf:

    echo   stream  tcp nowait  nobody  internal
echo    dgram   udp wait    nobody  internal
