I've read up some of the posts on this forum, but can't seem to find an answer. I have a web service within an Apache Tomcat instance installed on a Redhat linux server. I only have shell access to the server, and need to monitor outbound network traffic from my web service. Is there a unix command that will allow me to monitor all outbound traffic?

I'm thinking fiddler, but a unix version? I've heard of things like ntop and iptraf, but I don't think those will help me in this instance.

Thanks in advance!

Well you've mentioned tools that I'd possibly have mentioned, so if you're discounting them, you should really say why you are and what you actually want to acheive. phrases like "network monitoring" are so insanely open in interpretation it can mean so many different things. What do you actually want to monitor about it? TCP/IP throughput? HTTP level data?? Live or recorded data?

I want to monitor http level data. For example, the web service running in apache calls out to another 3rd party web service to retrieve data. I need to monitor the outgoing calls from my service to debug my web service since I have no access to the 3rd party service. I don't have much control over my QA and Production servers, so installing tools like ntop and iptraf aren't always options for me...which is why I'm wondering if there are any basic unix level commands that would give me what I need. If not, I can go to my operations team and see what options I have, but for now, I'm trying to avoid that if possible to save time and resources.

thanks!
