I've got a firwall installed on one of my servers.
After some searching I finally found one port thats open to use. So I've set up serv-u to connect through this port.
But when I connect from the outside I get a list error.

Does anyone know how I can solve this problem?

thanks in advance

Have you tried passive mode?

Yes, and that doesn't work

Can U Copy and Paste the exact error?

[R] Data Socket Error: Connection timed out
[R] List Error

mmm, Try to connect from your command prompt...

does you're rooter works properly?

Disable PASV mode on your ftp client

FTP protocol need at least 2 ports:
1) Control Connection (For example port 21)
2) Data Connection (For xample port 20 in active mode)

does the account has list permissions ?

u never know how stupid the problem can be

Listen what GogetaSSJ4 said... it's true


i think that running servu doesn't have any sense without another port open..most firewalls has standard ports opened ( like 21,80, 8080 etc) try one of them..also some firewalls do not block outgoing connections ....hope it helps

I think that the firewall blocks Data Connection Port.

try to connect with flashfxp and do these options:

open quick connect (F8)
go to Toggels
and aktivate the last option (use stat -l...)

then try again...

hope could help...

At Settings->advanced you can set up the ports used by data connection. these ports must be allowed to access the net.

First try the toggles for NAT PASV and STAT -L.

If not then its either your firewall or router. If you run the ftp on port 21 then port 22 needs to be open/forwarded too. If the port is 27501, then open/forward 27502 too.

Your words are not corrected. If FTP daemon run on port 21, the data connection run on port 20 (active mode).

What is the data connection port in pasv mode ??

Got the same problem

if the error looks like

PASV
entering passive mode
list 192.168.123.99
error: timeout

i mean if the network internal ip is displayed before the timeout connect with SU-Admin, open the server, at domains-->settings-->advanced-->allow passive mode use IP you can enter the external ip. in most cases this will work.

You should try to switch on the following option (presuming you use a good FTP client like FlashFXP).

- Site uses IP Masq / NAT / Non Routable-IP.

That should do the trick. To my knowledge you don't need to forward port 20 on your firewall but just 21. I only forward port 21 and it works like a charm.
