How to force IPv4 or IPv6?

[Winston Weinert]

Is there a way to force IPv4 or IPv6?

Use case that I encountered the necessity for this functionality:
I noticed Wikipedia blocks edits from my VPS IPv6 address. I wanted to force IPv4 to see if I needed to ask for a IP Ban Exemption for my VPS IPv4 address.

Thanks in advance!

no - you could force lynx to use ipv4 on the first lookup, but any
redirects would use dns, and then it would rely on _that_ address.

You could of course recompile lynx without the ipv6 support...

Ah. I was hoping I didn't need to manipulate my operating system for this functionality.

It turns out using LD_PRELOAD works nicely. Just whipped this up. Works perfectly on my Debian system: http://sprunge.us/GVEG?c

Hi,

your link is dead. Can you tell us how you solve it with LD_PRELOAD ?

This one. I suppose it describes the way you use LD_PRELOAD to force Lynx to use ipv4, right ? that's what I'm looking for
