cannot run ls after succesfull login to FTP server

[pob579]

Hi,
I have a weird problem.
From LAN with private addressing I can successfully login to FTP server (that probably is behind a firewall too).
But when I run "ls" command a connections hangs.
I can work with many others ftp servers during years from our LAN. And never had a problem
I have two firewalls Border Manager 3.0 (all client pc's
are going through).
My workstation goes to Netscreen firewall without proxy.
I have the same problem when trying to "ls" through both firewalls (to this particular ftp server running U-Ftp v.4.1
I can login and run ls from my home LAN through Linksys cable router and from public side of our business LAN.

Any guesses?

Thanks.
Michael.

I think you should set your client to work in PASV mode rather than PORT mode. As far as I remember, windows built-in ftp.exe does not support PASV mode, so you should get another ftp client (I'm using WS_FTP).
If you decide to try WS_FTP here are the steps to configure a connection:
1. Sites -> Add to sites
2. Follow the instructions in wizard until you reach "Host type" window, check the "Passive mode" box.

Hope that helps.

Hi (privet),
I found a client from which I can enable passive mode (cmd client FTPS)
It's easy to enable passive mode in IE too.
Tried both... not works.

Here is output from passive client ftps (at the end I run again Microsoft ftp.
May be you can suggest something else.
I also show "working" output from my home LAN.

Do you HAVE TO use command line clients ? I do not trust Microsoft's ftp clients, not to mention they are extremely uncomfortable. I suggest you to download Ipswitch WS_FTP trial and see if it works. Use the instructions I gave in my previous post.
If that doesn't help we'll think some more
