RE: Help - SFTP port 22

Nope; FTPS is not SSH and SSH is not FTPS.
Just because you have an app that uses SSH and refers to it as FTPS does not 
make it so.
RFCs are different; L4+ behavior is different.

*shy cough from the Unix guy in background*

Uhm, I do not mean to intrude but they basically are the same, they go
through an SSH tunnel.

SFTP is not more secure than SCP or vice-versa, they are only as secure as
SSH itself. (Which means, it's fine. Basically.)

They just use different interfaces, but they "work" the same, which is
inside an SSH tunnel. SFTP is just designed to "look and taste" like an FTP
server to the end user, but it is not dual port or anything either, it is
just a matter of what application you call on the other end of the SSH
connection. ISA would see both protocols as the same, from its point of
view.

And in any case... winSCP3 uses SFTP by default with fallback to SCP if that
craps out. It's made like this because sometime administrators will disable
one or the other in /etc/ssh/sshd_config for various reasons.

Basically all you need to do is allow SSH (which means outgoing connection
to port 22 on destination machine(s) (or the internet) and you are set.
That's what I did here, and it works wonderfully, I can toss and fetch files
from my Linux box at home in a really really strange fashion involving
tunneling SSH inside SSH to reach a machine behind my NAT ;)


Greg, I think you are confusing SFTP with FTPS, perhaps...

SSH is such a great protocol, it is a shame the OpenSSH implementation
doesn't work fully on Windows Server 2003 yet. (At least last time I
checked). With the venue of MSH, it will be even more useful... 

(And don't you love tunneling clear-text protocols through SSH? You can use
it as a "poor man's VPN" also.)


OH and FYI, ISA *does* support some amount of FTPS, it depends of it is
implicit or explicit, I believe... (I.E. SSL on port 21 instead of on a
dedicated port).

Now of course if you're talking about the FTP application filter ... Seeing
how braindead the FTP client in windows is, I don't doubt it is not
supported :)

What are you trying to achieve. My guess is you are trying to dump files
to a linux box or a windows box running an ssh server, behind the ISA
firewall. Instead of using SFTP, try using SCP. It's a more secure
protocol. See if that works the same.

SFTP uses TCP:989 & TCP:990; SSH uses TCP:22.
Which is it that you think you're using?

No; ISA does not support FTPS.
