[scponly] AG: Problem with Debian scponly 4.8 and winscp

[Kaleb Pederson]

Let's take winscp out of the picture and figure out what's going on after all.

What happens when you do the following:

ssh yourUser at yourHost /bin/pwd

Please send me the level 2 debug output for the above.  Next, follow 
the 'strace' instructions that are available on the FAQ page, gzip, and then 
send them to me.  You can send them to me personally or to the list.  Note 
that your password would be visible in them, so it should be a temporary 
password or user account.

Now that we know your permissions and chroot are both setup correctly, I just 
need to figure out what's going on, and the logs might not be right in this 
case, but I haven't looked at much of the winscp compat code either.

Thanks.
