Bug#694965: netcfg: Allow setup of pointopoint routes to reach gateway

Michael Neuffer-4
Package: netcfg
Severity: wishlist

Please add the possibility to specify pointopoint
routes when setting up the networking in the Debian Installer.

The result would look like something like this:

iface eth0 inet static
         address a.b.c.d
         netmask 255.255.255.255
         gateway e.f.g.h
         pointopoint e.f.g.h


Afterwards this routing would look like:

root@alpha:~# ip route
default via e.f.g.h dev eth0
e.f.g.h dev eth0  proto kernel  scope link  src a.b.c.d
root@alpha:~# route -n
Kernel IP routing table
Destination Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0     e.f.g.h         0.0.0.0         UG    0      0        0 eth0
e.f.g.h     0.0.0.0         255.255.255.255 UH    0      0        0 eth0



At the moment I don't know of any other way to configure this besides
skipping the network confguration at installation time and then doing a
manual network configuration afterwards.

Or is there some other option that I'm just not aware of?

With the growing shortage of IPv4 adress space this will probably become
more and more common.

At least for one large hoster in Germany this is already the standard
mode of operation if you want to have more then one IP address (for
virtual machines for example).

Cheers

Re: Bug#694965: netcfg: Allow setup of pointopoint routes to reach gateway - PR anniversary

Igor Scheller-2
Happy Birthday to you, happy Birthday to you, Happy Birthday little Pull
Request, Happy Birthday do uuuuuu!

As in happy second anniversary to this lonely PR that sadly gets ignored
by whoever has the right to merge it.

Did I did something wrong with it?
Is it really so poorly written that no one is even considering having a
look at it?
Is no body interested in fixing that (esp. as i'v heard from some people
that they also need that feature)?

I'll never know as it gets ignored :(

Sad greetings and in hope that this change has not to wait for a third year
Igor

Two remarks:

- Your change is missing a changelog entry in debian/change (generated
  with "dch --no-auto-nmu").

- The two commits should be squashed into one commit titled:

  "Add support for preseeded pointopoint mode"

Btw, I'm surprised the keyword is actually called "pointopoint" and
not "pointtopoint", but the manpage of ifconfig actually calls
it like that.

Hi Adrian,

thank you for your suggestions, I implemented them (and rebased the
branch on the current master).

that's definitely a point that i missed, sorry for that

I squashed the commits as they definitely are not useful

Thanks for the quick changes and rebasing. I will have a look at your
changes in detail later as I don't have much experience with the netcfg
package.

I just realized one other thing: Your change enhances the functionality of
the netcfg package. So it's most likely necessary to update the documentation
in this regard.

Otherwise, users won't be aware that the feature you are adding is actually
available.

It would be really great if you could have a look!

What part/Which parts of documentation do you do you have in mind here?

It's already available but only for some very interesting old hardware ;)

debian-installer has documentation on the network configuration. If you add a
new feature, it would make sense to document this feature in the manual so that
users actually know it's there.

I don't understand how this is related to hardware. You enable an additional
an additional parameter in the manual network configuration, so I assume
(I haven't checked the installation manual) that this new possibility should
be documented in the manual.
