hi nate,

I don't think so..

here's that output from lftp in debug mode again:

<--- 230 User zinextre logged in.
---> PWD
<--- 257 "/" is current directory.
---> PBSZ 0
<--- 200 PBSZ 0 successful
---> PASV
<--- 227 Entering Passive Mode (192,168,0,105,196,230).
---- Address returned by PASV seemed to be incorrect and has been fixed
---- Connecting data socket to (12.129.206.105) port 50406
---> LIST
Interrupt
---> ABOR

it is definitely *trying* to enter passive mode there.. the "Address 
returned by PASV seemed to be incorrect and has been fixed" message may 
be mucking it up though(?)

anyway, the client is set to use it:

kenneth@enlil:~$ lftp
lftp :~> set -a
set ftp:passive-mode on
 (trimmed a million other options...)

What I'm most confused by is mc working, but telnet behaving the same as 
lftp. I've confirmed mc is using passive mode as well. telnet in pasv mode:

230 User zinextre logged in.
syst
215 UNIX Type: L8

250 CWD command successful.
pasv
227 Entering Passive Mode (12,129,206,105,190,135).

list

I did do a firmware upgrade for my NAT router recently.. possibly since 
last using lftp. I just happen to have a fresh replacement for it too 
because it was crashing a lot last week. The firmware upgrade didn't 
stop the crashes, but 2-3 days later they did stop. I've been waiting 
for the crash to happen again before replacing it, but I'll go ahead and 
do it now and see if it changes anything

thanks.

I've been using lftp so far as a kind of drop-in ms cmd 'ftp' client 
replacement, but discovered a really nice looking mirror/reverse mirror 
option in the man page this morning that I wanted to try out
