Hi Eric,
thank you very much for your interest.

Well, I know about this issue. It was discussed in the tinc mailing 
list. But I'm compiling kernel with the same kernel version (2.4.18) as 
the distribution kernel have. And I'm compiling kernel from the same 
sources, as the distribution kernel has been compiled (probably, I 
didn't do it personaly ;-)).

Anyway, as I wrote: I did compile tinc against my custom kernel, and it 
didn't work again. But the same tinc (compiled against custom kernel 
headers) WORKS on distribution kernel. And that fact, brings me an idea, 
that something wrong is in a way, how I'm compiling kernel.

I'm just going to compile kernel from kernel-source-2.4.18 package with 
config file attached to kernel-image-2.4.18-sun4u package. So I should 
obtain exactly the same kernel, as the working kernel from woody is.

Thank you for your time and sorry my poor English. ;-)

        Best regards
