hi, friends
After `ftp.exe 10.0.2.2` successfully, why cannot i `ls` the host(OpenBSD) ?
Even passive mode doesnot work too. The guest is WindowsXP  running in qemu-2.x on OpenBSD.

Regards!

Three possibilities:

1. Is this one of those ftp servers (traditional) where the ftp ls
command actually invokes /bin/ls on the server?  In that case it
could be a server issue.  To test this try to ftp 127.0.0.1 from
the server itself (with the same username/password) to make sure
it is actually working.

2. Is this a situation where the secondary (data) channel doesn't
get through.  To test this, try to simply "get" a file which you
know is there.  The error message should be more revealing in such
cases, as it now only reflects the transmission (and possible file
access errors).  For extra diagnostics, turn on verbose mode
first.  If this reveals a problem, check if you are using some
kind of NAT logic between the virtual network inside qemu and the
host (I seem to recall that some qemu options do this).

3. Are you sure you are in passive mode?  Not all Microsoft
implementations of ftp.exe actually include the code for passive
mode, even when the corresponding copy of Internet Explorer does.

Enjoy
