Query on Hping

[kavitaB]

Hello all,

I want to use Hping tool to send tcp packet on ppp0 interface. When I send ICMP packet on ppp0 intrface I get reply from the target but when I try to send TCP/UDP packet I get error.
Command I use for sending TCP packet is
hping target ip -p dest port
but I get following message
ICMP Unreachable type=10 from ip=targetIP name=UNKNOWN

I don't know why I get this error on ppp0 interface and how to resolve it to send tcp/udp packet successfully to the target.

Please reply if anyone has any idea of this.

Thanks & Regards,
Kavita

You're not getting an error.. You're receiving an ICMP message as a response...

Looks like a Type 3 Code 10.. Communication with Destination Host is Administratively Prohibited..

Run something like Ethereal while doing this.. Then you'll see you're really sending something and receiving a response..

(This shouldn't be in the Tutorials section but in Network Security)
