C2T2 -- X from older RedHat install, external WWW access

[Darryl Gamble]

Thanks very much Alan.

1. I found that /usr/sbin/gdmconfig was set to disallow TCP traffic from 
the Security tab.   I've turned that off.

2. You mentioned that I should turn off ECN given that my default route 
is working alright.   I believe it is working properly given that I can 
ping www.yahoo.com.   I tried that using "echo 0 > 
/proc/sys/net/ipv4/tcp_ecn" and low and behold my telnet to port 80 works!
I am now assuming that one of my ISPs routers is failing on the ECN.   
Is there an easy way to check which router is causing the failure?
