[shawnl]# I get action from tcpdump when listening on port 8000 but nada on 80; is it safe to assume that it is blocked by an OUTSIDE source? I get results from tcpdump on ports 22 23 25 8000 but nothing on 80... The other weird thing is that i used a "dynamic IP redirection" service from no-ip.com and it hits my page - the weird part is even when i monitor port 8000 and access my page I don't see anything from tcpdump when accessing the page that way. Here is the command I used #tcpdump -i ppp0 tcp port X Thank you for your help, Shawn -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
