check the logs:

tail -f /var/adm/syslog/syslog.log

try a ftp

For active and passive ftp to work right, you need ports 20 and 21 not to be blocked by firewall.

Hi Yuli,

Is this post related to your earlier post "ls not working" ? It seems port no. 20 is bothering you a lot.

The passive mode can be enabled uding ftp -p .

[yuli_3]

yes,

why must in passive mode??
