To store certain command you would like executed at boot time consider using the “/etc/rc.local” file.
[codesyntax lang=”bash”]
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sudo iptables -A INPUT -p tcp --dport 10000 -j ACCEPT sudo iptables -A INPUT -p tcp --dport 21 -j ACCEPT exit 0
[/codesyntax]
These two commands make sure the ports are open and ready for use.
