[9fans] open ports?

["John Floren" <slawmaster@gmail.com>]

When I scan my recently-installed Plan 9 box, I get *tons* of open
ports listed... however, when I try to connect to some of them (ssh,
for example), I get an refused connection. What's the deal here? Are
*all* of these services actually running?
Here's the output of nmap:
PORT      STATE SERVICE
7/tcp     open  echo
9/tcp     open  discard
19/tcp    open  chargen
21/tcp    open  ftp
22/tcp    open  ssh
23/tcp    open  telnet
25/tcp    open  smtp
53/tcp    open  domain
80/tcp    open  http
110/tcp   open  pop3
113/tcp   open  auth
143/tcp   open  imap
513/tcp   open  login
565/tcp   open  whoami
567/tcp   open  banyan-rpc
993/tcp   open  imaps
995/tcp   open  pop3s
17007/tcp open  isode-dua

Slightly confused by... everything,
John F.
