comment How do I make a privileged port non-privileged in Redhat 5?
No. It's part of a java web archive (war) as a ServletContextListener. When Tomcat starts the war, the listener then kicks off and binds to the port. My gut tells me that my boss would not want to tear this process away from the war.

After doing some research, it appears that xinetd does not support redirecting a UDP port. :( SLP uses broadcast datagrams. So I cannot use the xinetd solution. That being said, this looks like it would be great solution for other situations.

I'm intrigued, Jodie. Why is this an awful idea?

I'm not for sure, but the proxying may not work since I'm trying to listen for and send out multicast UDP datagrams, not TCP HTTP packets. But it may be worth looking into.

comment How do I make a privileged port non-privileged in Redhat 5?
Thanks for the response, but am I asking the same question? My understanding is that jsvc will start tomcat as root and then drop down to a normal user. Let's assume that I start Tomcat this way. I still couldn't open up port 427, could I? By the time Tomcat starts my war, I'd be a regular user, wouldn't I?

comment How do I check if a port is open on Red Hat Linux/CentOS
I like the idea of using trace route. Unfortunately, trace route for windows isn't as functional as I need it to be. The iptables command helped quite a bit. If I'm reading it right, it looks like I'm not running a firewall on this box, so something is happening on one of the routers or the TTL is too short.

Thanks. I'm able to see that my app is listening, I'm just unable to check if the port is being blocked by the firewall.

comment How do I check if a port is open on Red Hat Linux/CentOS
netstat seems to show me what ports are listening and what connections are established, but how do I know if a port is actually open? When I run my application, I see that it's listening, I just can't communicate with it from my laptop to the server (about 4 hops). I'm interested in what the cause of this lack of communication is. Is the port blocked or are my datagrams being dropped?
