Allow ftp connection

[warrenliang]

Good afternoon:

On a Redhat Enterprise AS 3 server, firewall is up and running. How to open the firewall up to allow ftp connections from clients to this server?

Thanks.
Warren

Don't know if this applies to RHEL, but on FC, you can run setup as root from a console. In the setup menu, go to Firewall Configuration and allow FTP traffic from there.

Barring some odd configuration of your existing rules:

iptables -I INPUT -p tcp -m tcp --dport 21 -j ACCEPT
iptables -I INPUT -p tcp -m tcp --sport 20 --dport 1024:65535 -j ACCEPT
service iptables save

The second line is required for passive ftp transactions.

Most redhat implementations also require loadinng the ftp_conntrack module to allow through a firewall, though may only apply to NAT... it's been a while.
