Hello,<br>configuring iptables rules, <br>how I can find out if one port number I want to use is already in use? <br>example:<br><br>$IPTABLES -t nat -I zone_wan_prerouting 1 -j ACCEPT --protocol udp --dport ${UDP_PORT}  --destination localhost<br>

$IPTABLES -t nat -I zone_wan_prerouting 1 -j ACCEPT --protocol tcp --dport ${TCP_PORT}  --destination localhost<br>$IPTABLES -t nat -I zone_wan_prerouting 1 -j ACCEPT --protocol tcp --dport ${TCP_HOST_PORT}  --destination localhost<br>

<br>How I can check if these ports (UDP_PORT TCP_PORT TCP_HOST_PORT) are in use from another application?<br><br clear="all"><br>-- <br>&#39;The Magic Is In the Movement&#39; <br><br>Marco Savo<br>SW Engineer<br><br>882 East Glenn St.<br>
