Protocols guarddog has not support yet but are useful to have
TFTP: (for network booting)
netconsole: (for kernel debugging)
rdesktop: (for remote windows view)
svnserve: (for non ssh suvbersion users)
smtp over SSL: (It is deprecated but maybe useful for some)
Others not listed here:
apt-proxy: (port = 9999, Debian apt proxy daemon)
SANE: (cannot be firewalled properly. Seriously compromises sustem security)

protocol name="smtp over SSL">
<longname>SMTP - Simple Mail Transfer Protocol over SSL</longname>
<description>SMTP is used to transfer and deliver email across the network.
It is the standard for transmitting email across the Internet. This enables
the SSL (secure socket layer) SMTP transmission. Note that this method
for mail transmission is deprecated and you should use TLS instead which
uses the normal port 25 instead.
