svc:/network/stdiscover:default
svc:/network/stlisten:default

these two do tag discovery whatever that is. Doesn't seem very useful, from what I can see, so better safe than sorry, and turned them off svc:/network/telnet:default svc:/network/shell:default svc:/network/login:rlogin svc:/network/ftp:default because it's not 1990... svc:/network/smtp:sendmail we'll probably replace this with exim at some point.
