I have a NetWare 6.5 SP2 (plus various patches, see below) server that I
wanted to try using secure FTP with and ran into the following issue. I
am not sure how to proceed with debugging this problem.

What follows is what I get when attempting to connect using the ftp-ssl
command from a Debian Linux (sarge distribution) system to the NetWare
server. Everything looks good until I try to get a directory listing.

I have not yet found any error messages in any of the server logs.

~$ ftp-ssl server.xxx.xxx.xxx
Connected to server.xxx.xxx.xxx.
220 Service Ready for new User

The NetWare 6.5 server has the following patches...
NW65SP2
NWLIB6A
SECUPD6A
WSOCK6E
AP2052
NMAS235
NCPUP1
MOD_EDIR 1.0.8
NWFTPD10

I would like this to work. My customers would be ecstatic if this
worked. What can I do to further troubleshoot this?

Thanks,
Yancey
