Why does connmand add and delete route to 87.106.208.187?

Hi

Each time connmand starts the following is logged:

connmand[323]: eth0 {add} route 87.106.208.187 gw 192.168.0.1 scope 0 <UNIVERSE>
connmand[323]: eth0 {del} route 87.106.208.187 gw 192.168.0.1 scope 0 <UNIVERSE>

I can see that I'm not the only one wondering: https://01.org/jira/browse/CM-657

The source code does not seem to contain the IP adresse, nor does the IP exist in my /etc or /var/lib/connman/

Are there typos in your title and code block, or am I just completely confused? Is this about conman?

EDIT: sorry, I am just completely confused and/or slightly dislexic. No matter how many times I read it, I kept seeing "command add and delete ..."

Nope, it's about https://www.archlinux.org/packages/comm … 4/connman/ and the daemon is connmand

Is 87.106.208.187 your DNS server? connman by default creates a local DNS server and creates appropriate routes so that it works. If you don't want that, start it with --nodnsproxy

No, I use dnsmasq on my router, so it's 192.168.0.1

Some more lines from my log to give some context:

That's weird; the connman source doesn't contain any reference to that IP. But I think it's no coincidence that the rdns of that IP is senator.holtmann.net; while the author of connman seems to be "Marcel Holtmann <marcel AT holtmann.org>". If you're interested you should have a look through the sourcecode of the application

Yeah, you are right.

I downloaded http://www.kernel.org/pub/linux/network … .23.tar.xz which is used in the PKGBUILD (https://projects.archlinux.org/svntogit … es/connman) of the version I have installed.

I have checked the source code for "holtmann" and the IP:

$ grep -r holtmann

$ grep -r 87.106.208.187
zsh: exit 1     grep -r 87.106.208.187

No dice. Maybe there is something in the configure or build step that adds the IP, so I also checked the different binaries using strings, but nothing matches.

One explanation might be that the author accidently left the IP/host there for debugging/custom configuration. But, since the source code doesn't contain any references to that, it is indeed a mystery where does this IP come from.
