The `pfinet` server is a hacked Linux internet implementation with a glue layer
translating between the Hurd [[RPC]]s and the middle layer of the Linux
implementation.


# Bugs

## Those Listed on [[Open_Issues]]

## [[IPv6]]

## IRC, freenode, #hurd, 2013-04-03

    <braunr> youpi: there are indeed historical bugs with small packets and
      tcp_nodelay in linux 2.0/2.2 tcp/ip
    <youpi> oh
    <braunr> http://jl-icase.home.comcast.net/~jl-icase/LinuxTCP2.html

## MAC Addresses

[[!tag open_issue_hurd]]


### IRC, freenode, #hurd, 2013-09-21

    <jproulx> what command will show me the MAC address of an interface?
    <youpi> ah, too bad inetutils-ifconfig doesn't seem to be showing it
    <youpi> I don't think we already have a tool for that
    <youpi> it would be a matter of patching inetutils-ifconfig


## Routing Tables

[[!tag open_issue_hurd]]


### IRC, freenode, #hurd, 2013-09-21

    <jproulx> Hmmm, OK I can work around that, what about routing tables, can I
      see them?  can I add routes besides the pfinet -g default route?
    <youpi> I don't think there is a tool for that yet
    <youpi> it's not plugged inside pfinet anyway

    <youpi> I was thinking about just using liblwip this afternoon, btw
    <braunr> what is it ?
    <braunr> hm, why not
    <braunr> i would still prefer using code from netbsd
    <braunr> especially now with the rump kernel project making it even easier
    <youpi> well, whatever is easy to maintain up to date actually
    <braunr> netbsd's focus on general portability normally makes it easy to
      maintain
    <braunr> the author of the rump project was able to make netbsd code run in
      browsers :)
    <braunr> and he actually showed clients using the networking stack on
      windows, remotely (not in the same process)
    <braunr> so that's very close to what we want
    <youpi> indeed
    <youpi> though liblwip is exactly the same portability focus :)
    <braunr> apparently, for embedded systems
    <youpi> but bsd's code is probably better
    <youpi> yes
    <braunr> i think so, more general purpose, larger user base
    <youpi> I used it for the stubdomains in Xen
    <youpi> (it = lwip)
    <braunr> ok

Cloudius OSv apparently have isolated/re-used a BSD networking stack,
