I read somewhere that SSH can run over TCP port 22 or UDP port 22?
But I thought SSH is over TCP 22 only. Can UDP be used as ssh transport??

What you probably saw was a reserved port listing. In many cases, IANA has
reserved both UDP and TCP ports for the same service, just for
consistency. In some cases it's meaningful to run a service over either
UDP or TCP, but in most cases it doesn't make sense.

I have the following setup.
2 FreeBSD 3.3 Servers. Server A is the PPP listening Server. Server B is the
Using TCP as the transport all works OK. PPP connection work just fine. Once
I change the Client to use UDP PPP can't complete the connection.
In inetd.conf I have the following on server A
ppp-in stream udp nowait root /usr/sbin/ppp ppp -direct ppp-in
Server A ppp.conf
set timeout 0
set ifaddr 10.0.4.1 10.0.4.2
On server B
set timeout 0
set escape 0xff
set device <ip.address>:6669/udp
set ifaddr 10.0.4.2 10.0.4.1
set log Phase Chat Connect hdlc LCP IPCP CCP tun
set Authname router1
set Authkey password
All fireway rules are set to allow everything for now.
subsitute all TCP with UDP and all stops. I can determine from the PPP log
that a connection is denied but I belive this is due to UDP port 6669 is not
listening on the reciever server. I can get the same error message using TCP
but have the client use the wrong TCP port number.
Any ideas ??????
