hello,

we have a hardware node with two VZs, both are given this error when we try to connect with ftp:

Status: Connecting to xxx.xxx.xx.xxx ...
Status: Connected with xxx.xxx.xx.xxx Waiting for welcome message...

Command: PWD
Response: 257 "/" is the current directory

Command: PASV
Response: 227 Entering Passive Mode (xxx.xxx.xx.xxx,139,44).
Command: LIST
Error: Transfer channel can't be opened.
Error: Could not retrieve directory listing

so the problem must be at the node.

any help to fix that?

thanks.

Try setting your ftp client to 'PORT' mode rather than PASV, if that works then its a firewall blocking the range used for the PASV ports.

As your using proftpd look in /usr/local/etc/proftpd.conf (location may be different) and the lines you are looking for are something like this:

# Restrict the range of ports from which the server will select when sent the
# PASV command from a client. Use IANA-registered ephemeral port range of
# 49152-65534
PassivePorts 49152 65534

So basically you need to allow the ports listed above for passive transfers

I found it:

ServerName "ProFTPd"
ServerType standalone

Port 21
PassivePorts 35000 35999
UseReverseDNS off
TimesGMT off
TimeoutLogin 120
TimeoutIdle 600
TimeoutNoTransfer 900
TimeoutStalled 3600

PassivePorts 35000 35999 means that we can choose one port form 35000 to 35999 or we must open all of then?

thank you!
