RE: [ASL] AODV-UIUC help

[Luo Y. <EY...@nt...>]

Vikas:
 Thank you for your quick reply.

When I tried to move all machines together, i.e. every node can see the
other two nodes directly, The PING test between any two nodes was
successful, so it is with SSH. But both failed when it requires a
multi-hop.=20

*	There's another thing I don't know whether it's helpful. When I
compile the AODV-UIUC source code, I got one warning message:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
aodv.cc: In member function `void aodv::resendRREQ(void*)':
aodv.cc:1033: warning: taking address of temporary
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

*	I also checked the iptables with "iptables -L", the output is:
		[root@localhost /]# iptables -L
		Chain INPUT (policy ACCEPT)
		target     prot opt source               destination
		=20

		Chain FORWARD (policy ACCEPT)
		target     prot opt source               destination

		Chain OUTPUT (policy ACCEPT)
		target     prot opt source               destination

The table is empty. Should I add some entry to the Chain FORWARD?

Thanks

There are too many things in a "system configuration: to just "kindly=20
tell".=20

As a first guess, I would suspect you have turned on a firewall
(iptables)=20
which is eating up all the ping packets.

Can you ssh.
