openssh unix dev - Mar 2001 - sftp over 2 hosts?

Hi list,

I tried sftp and it works perfect via a direct connection between 2 hosts. Our
situation is that we have to go from our intranet through a firewall gateway to
the internet and then to a third server. With "normal" ssh this works
via: "ssh -t hosta ssh hostb". It seems to me that this doesn't
work with sftp ;-((. Would it be complicate to implement?

Thanks
Stephan

you don't need to use
	myhost$ ssh -t hosta ssh hostb
use this instead:
	myhost$ ssh -L 1234:hostb:22 hosta
	myhost$ ssh -p 1234 localhost
or
	myhost$ sftp -o 'Port=1234' localhost

-m

thanks, that works, but the problem is that I have two open connections now, but
I need actually only one. Furthermore the command

myhost$ ssh -L 1234:hostb:22 hosta

gives me a promt back, so I have to open a window and to make small and to open
a next one for the command

myhost$ ssh -p 1234 localhost

That works, but in my opinion it is not user friendly.
