    testing: in basic-pluto-12 replace port 22 (sshd) with the echo port (7)
    
    Since systemd has assimilated /etc/inetd.conf, also add echod.sh
    (using socat) to emulate inetd's implementation of the Echo Protocol
    (RFC 862).

    kvm: add socat to package list
    
    It turns out that ncat can't correctly emulate inetd's echo service
    but socat can (and who knows what systemd's come up with).  It also
    helps explain why:
       echo foo | nc east 7
    seemed broken.
