Re: [leaf-user] Does dropbear support port forwarding?
I've fixed a couple of bugs in Dropbear's port-forwarding since version 0.41, you might be hitting one of them. Version 0.43 might be worth trying? (I think K.P. has put a package at http://leaf.sourceforge.net/mod.php?mod=userpagemenu=91017page_id=51 ). Let me know how it goes, if that doesn't help, we can go bug-hunting.

Ooops!

Re: [leaf-user] Does dropbear support port forwarding?
Sorry that I cannot help but FYI I also got trouble with port-forwarding with dropbear. I used it to Remote-Terminal to Win2K server and IIRC I could go into the login screen but then things stopped. Switching back to SSHD and everything worked. However it was about half a year ago and later versions of dropbear may fix that.
