Hello!
Thanks for the reply!
But I'm not running any firewall on my server...
Here's my /etc/rc.conf
<rc.conf>
..
..
#named_enable="YES"
firewall_enable="NO"
#natd_enable="NO"
#firewall_type="open"
#firewall_script="/etc/rc.ipfw"
enable_quotas="YES"
check_quotas="NO"
linux_enable="YES"
...
...
</rc.conf>

So, my problem shouldn't be with the firewall on my server...

About the configuration of  FTPd, I cannot find the config file (ftpd.conf
or ftpd.config or ftpd.cf )on my server(FreeBSD4.8 stable, built yesterday).

Note that I'm trying to connect to FreeBSD from a windows workstation....
both the workstation and the FreeBSD server are in the same LAN.... From my
Windows box, I can easilly connect via FTP to other Linux sercers in my LAN
or even out of the LAN.. But when I connect to my FreeBSD server, it connecs
well... but I cannot do anything useful on the server.... I get the error
"...425 can't build data connection: operation timed out..."
My server was running FreeBSD4.6 before and I didn't have any trouble with
FTPd .... I just upgraded yesterday.... and still, I haven't noticed this
problem.... I start getting this error just a while ago... :-( ... I've
rebooted the server... but it didn't help

Thanks for the support.

Arcadius.
