Hi Dominic,

   This patch didn't seem to work when I installed it. I tried out a few combinations of IP-version options at the web100srv and web100clt, and a complete list of the combinations I tried is attached alongwith.

Also, its somewhat difficult to follow the logic you have added. Is there a way you could clean up the ifdefs to make the code easier to read? The ternary operators and if-else's spread across the ifdefs are tough to debug. A few more comments may help too.

Thanks again, and sorry about the delayed response.

Sorry for the followup, but I found a bug in the last version.

Attached please find a better version.

Please find attached a patch to improve IPv6 support in NDT. With this patch, if no address family is specified on the command line, web100srv will listen for both IPv4 and IPv6 connections (if supported). Similarly, clients will attempt to connect to either IPv4 or IPv6 servers if address family is not specified on the command line.

Thank you for your consideration.
