I am currently working on a project involving networked Water COMs. I
have noticed an issue where I get spotty connectivity to and from the
Water COMs. I attempted to troubleshoot this issue and found that
each gumstix has both an IPv4 address and an IPv6 address.
Occasionally the two IPv6 addresses match and I think that this is
where I start seeing the error. Note that when I first starting
seeing the error I did not have the USB console connected to either
COM and can't exactly say what was happening. I configure the IPv4
address by editing /etc/network/interfaces, but I don't seem to have
control over the IPv6 addresses. When I use modprobe, I see that
there is a module named "ipv6" running.
Therefore, I have the following two questions:
1. Could the duplicate IPv6 addresses be causing my issue? I only
ping/connect using IPv4 addresses.
2. If the IPv6 addresses are the source of my problem, is there a way
that I can disable the IPv6 module? Will it harm anything? I'm
running a fairly standard distribution of Angstrom.
