Re: [mpls-linux-general] problem with iptables. Error invalid argument type.

[J. N. <oc...@gm...>]

I  am aware that netkit have MPLS support but I have to make with VNUML
because I have made before another works with that platform and now that
after a lot of work I can have an MPLS kernel running on it I want to make
it work. I think that the only thing that it remains is download a version
of iptables (patched with mpls support) that runs with 2.6.18.1 or trying to
compile it with KERNEL_VERSION option, but by now I cannot achieve it :(

By the way, I cannot get access to your perforce server with visual clinet,
it launches an error saying that the server is too old:

only 2004.2 or later servers supported by Perforce Visual CLient.

I remember that moths ago I can get access to it. Anyone have the same
problem?

Thanks for all James and sorry for my english
