Re: Add VLAN with Guile Netlink link-add

[Niklas Schmidt <snlabs@posteo.net>]

Thanks a lot, Julien!

I really like the short examples in the documentation. They are very 
helpful to me.

Adding the VLAN link works now.

For anyone interested, here is what works for me, based on Julien's 
documentation:

As root (in order to configure network interfaces):

   root@guix ~# guix shell \
   > --pure \
   > --with-latest=guile-netlink \
   > guile guile-netlink \
   > -- guile
   guix shell: warning: cannot authenticate source of 'guile-netlink', version 1.1.2

   convenient interactive line editing and input history.
   
   Consider installing the 'guile-colorized' package
   for a colorful Guile experience.

   scheme@(guile-user)> (link-add "ens3.10" "vlan" #:type-args '((id . 10) (link . "ens3")))
   $1 = #t
   scheme@(guile-user)> (addr-add "ens3.10" "192.168.10.219/24")
   $2 = #t
   scheme@(guile-user)> (link-set "ens3.10" #:up #t)
   $3 = #t

A ping over the newly created link works.


Greetings
Niklas
