RE: Can't ping a Windows computer on Linux

This is a subtle one – you are trying to use Windows XP as a pure IPv6

node. I know that DNS resolution on Windows XP works only over IPv4,

and there may be other things that still require IPv4. It works OK in a

dual stack network (IPv4 and IPv6), but it won’t fully function in a pure

IPv6 network. Vista will. FreeBSD will. Not sure about Linux, but it

should, esp. if you have installed the full USAGI IPv6 stack.

 

Also, using Site local addresses should work, but if possible, use

Unicast (e.g. 2001:.. or 2002:… ) addresses. Either assign them

manually (e.g. using “net sh” in Windows) or provide a Router

Advertisement (RA) server somewhere on each segment and let

the stateless autoconfig create them for you automatically.

If you insist on using link or site local addresses, don’t

forget to include the interface id everywhere you use the address

appended to the end of the address (e.g. <addr>%4). I’m not

that familiar with site local addresses, but the %1 after yours

in your ipconfig looks odd for some reason. How did you create

the site local addresses?

Yeah it's in french but you should be able to understand.

Hi Jason,

I'm not sure what scope/interface is the %1, so probably you're using a
wrong one. If you can post the ipconfig /all it will be much easier, good if
you can show us the ifconfig for the Linux box. 

Also, make sure that you have disabled the Windows Firewall or at least
allowed ICMPv6.

Regards,
Jordi

Asunto: Can't ping a Windows computer on Linux

My Windows 2003 computer has an adress that ends with a "%1" and my Linux
computer has what I would call a normal IPv6 adress. 
So when I try to ping either of the two together, well I can't reach them.
