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.
