[scli] SCLI and IPv6 Agents

Any chance of dual supporting IPv4/v6? It looks like ./scli/cmds.c and ./scli/fmt.c would need to be updated to use sockaddr_storage, add AF_INET6, and use getaddrinfo instead of gethostbyaddr.

Also, is there anonymous SVN readonly access for https://cnds.eecs.jacobs-university.de/svn/schoenw/src/scli/trunk/ ?

Thanks much, -Jim
