Solaris DoS kit

This was used by a btinternet user against www.amazon.com via one of our
Solaris 2.6 servers.  Expect they got in via an old sadmind vulnerability
which wasn't patched on a server which really should have been behind a
firewall.

Most of this is pretty uninteresting, wipe is just a utmp/wtmp wiper for
example.

The kit adds telnetd to /etc/inetd.conf, removes sadmind from /etc/rpc and
adds it to /etc/init.d/rpc and installs a bogus sadmind binary which is
used for denial of service attacks.

The DoS type is spoofed source random tcp-high to tcp-high on target host.
