hello everybody
i ''m having problem accessing FTP sites on the net
through my linux firewall
here is what happened when i'm connecting using ftp
command from win2k prompt
ftp> open
To 202.xxx.xx.xxx
Connected to
202.xxx.xxx.xxx.
220 flsvr Microsoft FTP Service (Version 5.0).
User
(202.xxx.xx.xxx.:(none)): xxx
331 Password required for
amon.
Password:
230-Welcome To FlSvr Perkom FTP Site
230 User xxx
logged in.
ftp> ls
500 Invalid PORT Command.
150 Opening ASCII mode
data connection for file list.
(then the connection seems to
hang out..)
and then when i'm using windows explorer to open
the ftp
the error is :
--FTP Folder Error--
An error occured opening that folder on the FTP
server, make sure you have permission to access that folder
Details :
200 Type set to A.
500 Invalid PORT command
500 "LPRT
6,16,0,0,0,00,0,0,0,0,0,0,0,0,0,0,0,9,4......':command not
understood
BUT if
i'm using WS-FTP here is the log file.
ftp> open
To 202.169.39.132
Connected to
202.169.39.132.
220 flsvr Microsoft FTP Service (Version 5.0).
User

ftp> ls
500 Invalid PORT Command.
150 Opening ASCII mode

some of my friend told me that because WS-FTP
support "passive transfer mode" so the program can connect through the firewall.
Which is not supported if i'm using FTP ftom command or windows
explorer
is there any one can tell me what did i miss on my
firewall rules ?
can someone give me a clue ??
thanks
