[gentoo-user] dhcpcd: disable zerconf

[-- Attachment #1: Type: text/plain, Size: 1067 bytes --]

Hello,

How does one disable zerconf for dhcpcd or at all in Gentoo for that matter?

Search results gave me this little snippet but it doesn't apply to Gentoo.

[HowTo Disable the “ZEROCONF” in Linux](http://blog.omotech.com/?p=1005)

[bash] # vi /etc/sysconfig/network

NOZEROCONF=yes # or no (either answer will disable the “ZEROCONF route”)

And here again it's the same thing (Fedora).

[Disable the zeroconf route](
https://linuxstgo.wordpress.com/fedora-16/disable-the-zeroconf-route/)

Thanks,

Do you mean ipv4ll? Add noipv4ll to /etc/dhcpcd.conf .

that works.  myself, i like to totally misconfigure it and then change access to read only even for root, usually takes care of updates starting it.  i've also sabotaged one of there scripts so it just always returns a 1, i.e. error, also locked down afterwards.  the zero config stuff is tricky sometimes with updates and installs.  I also block router solicit and router advertising in the firewall.  I've been owned before, can't be too careful (pretty obvious when the system monitor won't launch, kinda pathetic when they knock out the sysmon for gnome but leave the one for kde working, glad i had both).

Is your scenario related to running Gentoo on a workstation?

I am using gentoo as a hypervisor for lxc and my veth interface for my
guest is getting assigned a 169.254.x.x address (host side). I can't see it
from inside the guest, but it's screwing with my routing tables.

it's mostly from the evil centos days (after it was bought out).  I assume similiar files are involved with gentoo, as earlier response suggested.  when my health improves i'll be putting gentoo on several systems and a couple ancient servers, did get it working nicely on one desktop.  I like  a steep learning curve, but not while i'm recovering.

  CentOS is a free Redhat clone.  Zeroconf (Avahi) is Lennart-ware that
you-know-who got into Redhat's OS.
https://en.wikipedia.org/wiki/Avahi_%28software%29  It's probably
impossible to pull Avahi out of Redhat / CentOS, just like with Systemd
and Pulseaudio.

> I assume similiar files are involved with gentoo...

  It should not be mandatory in Gentoo, per se.  If you have avahi
installed, try "emerge -p --depclean avahi" first, before doing it for
real.

fortuanately i got out of it by then, version 7 hates my hardware, i was using 6.x  for a couple years (off line, glad i saved local archives), when it first hit V6, not surprisingly it kept trying to sneak in and was resistant to removal so i quickly looked at sabotaging it.  prevoiusly used open susse and liked the ability to specifically break packages by not installing "required code", i don't need my media player to talk to the world.

not at all surprised by the source.  like i said rh spent good money to take over centos.  also used scientitic linux which is somewhat fixed.  Then there are the impossible to see/use colors mc wants to use, i started using computers over leased lines on decwriter 2 printing terminals, I can edit in b/w, though i played with mc's colors as well.  that's why i love linux, most problems are easy and have well documented solutions.

now, if i just knew how to search for "root-", which is impossible with modern search engines, they insist on processing quoted text and turn punctuation into a wild card.  I prefered being the cleaver and intelligent one, i hate when "new" software thinks it knows what i want, there was a time when you could look up part numbers and actually find what you were looking for.  hence, Gentoo and i'll be playing with devuan as well, and doubtless will experiment with "linux from scratch".  i tend to run desktops like servers, i love having a system running without reboot for months except for updates that require a restart.

in any case, that's why i know how to futz with zeronconfig/avahi.  figured it out, it was obvious once i looked that it was easy to have it installed but configured to crash and go away fairly harmlessly.

sorry, that was "root-1" i had tried to search for online.  seems that particular hole has likely been patched, but it's maddening that search engines will in fact no longer leave your' quoted text unmolested,  there's no was to escape the punctuation.
