Traceroute strange behaviour

[Mahavir Jain]

Hi,

I found a strange behaviour within firewall blocking UDP ports or even
ICMP echoes.

$ traceroute  -n  www.yahoo.com

traceroute to www.yahoo.com (209.131.36.158), 30 hops max, 38 byte packets
 1  192.168.10.3 (192.168.10.3)  0.949 ms  1.084 ms  0.981 ms
 2  192.168.10.1(192.168.10.1) 1.944 ms  2.301 ms  1.951 ms

This entirely takes around 7-8 minutes, while standard linux command
takes just 1-2 minutes. Beacuse of this much delay my application GUI
just times out due to standard HTTP request.

Even there is no option TCP based traceroute for bypassing firewall settings.

Even trying impossible host such as   $ traceroute -n 1.1.1.1

Any Workaround , I am using busybox 1.12.0 .


Thanks
