route: message...

On FreeBSD 15.0-RELEASE-p5 I have all the time error message:
route: message indicates error: File exist
add host 127.0.0.1: gateway lo0 fib:0: route already in table
route: message indicates error: File exist

I do not have problems but I like to know where in the settings should I look for.

In /etc/rc.conf I have:
Code: 
hostname="fernandel"
in /etc/resolver.conf

Code: 
nameserver 127.0.0.1
and in /usr/local/etc/unbound/unbound.conf
Code: 
interface: 127.0.0.1
access-control: 127.0.0.1/8

Thank you.
 
Why are you posting information relating to DNS when you have an error involving routing?

Post your whole rc.conf.

There's nothing in your rc.conf that seeming does anything with routes, except maybe DHCP on your re1 interface. But that's not going to touch lo0 or 127.0.0.1. Anything in /etc/rc.local perhaps? Also check for files in /etc/rc.conf.d/.

I do not have /etc/rc.local and /etc/rc.conf.d/ is empty.

I suggest enabling verbose booting, that might give some clues where and when this error happens.
 
So your route already has a (correct) default gateway.

My read is that (something) is trying to create a gateway to your loopback device -- which is odd :-)

add host 127.0.0.1: gateway lo0 fib:0: route already in table

BTW: (my FreeBSD host): Loopback device is defined (the same way) yours is:

At the moment I would say the (ERROR IS GOOD) because route(8) is stopping something strange from happening in your routing table. Next step would be to see where that "add host" command is coming from.
 
Anything in /etc/dhclient.conf? Perhaps it's trying to set additional routes (that aren't needed because it's an implied route).
 
Same here:

Code: 
Apr 11 15:41:22 <console.info> edge kernel: [244] route: message indicates error: File exists
Apr 11 15:41:22 <console.info> edge kernel: [244] add host 127.0.0.1: gateway lo0 fib 1
Apr 11 15:41:22 <console.info> edge kernel: [244] add host 127.0.0.1: gateway lo0 fib 0: route already in table
Apr 11 15:41:22 <console.info> edge kernel: [244] Additional inet routing options: log ICMP redirect=YES gateway=YES.
Apr 11 15:41:22 <console.info> edge kernel: [244] route: message indicates error: File exists
Apr 11 15:41:22 <console.info> edge kernel: [244] add host ::1: gateway lo0 fib 1
Apr 11 15:41:22 <console.info> edge kernel: [244] add host ::1: gateway lo0 fib 0: route already in table

And in rc.conf:

Code: 
network_interfaces="lo0 igb0 igb1 igb2 igb3"
ifconfig_lo0="inet 127.0.0.1"

In sysctl.conf:

Code: 
net.fibs=2

My system is old. It came along since Rel. 2.2.1, and probably wasn't freshly installed since Rel. 10 or earlier.
At some point somebody told me that the "ifconfig_lo0" setting is no longer necessary (but as we have just seen in another thread, it is still useful to have it there, to know the place where to properly add further options), and at some point the fibs did appear.

It seems to me somebody did insert whatever automation into the /etc/rc.network & friends, and didn't do it all too cleanly. But as long as things just work, I didn't bother to look at it and possibly clean it up.

Neither is the network_interfaces, it gets those automatically too. The OP doesn't have those settings in his rc.conf though, so that can't be it.

You sure? The one I checked didn't have that routing error message anywhere.

Do you have any jails running?

No, I do not have jails. And I check agin and there are no errors but on the display I see those failed messages...
I do not understand.

Okayokay. Mostly clean test installation with:

Code: 
route: message indicates error: File exists
add host 127.0.0.1: gateway lo0 fib 0: route already in table
add net default: gateway 192.168.97.17
route: message indicates error: File exists
add host ::1: gateway lo0 fib 0: route already in table
 
So...

pfsync
devd

Somewhere inside rc.d/routing:

Code:

+ suffix=''
+ eval echo '${route__loopback-}'
+ echo -inet 127.0.0.1 -iface lo0

+ /sbin/route add -inet 127.0.0.1 -iface lo0
route: message indicates error: File exists
add host 127.0.0.1: gateway lo0 fib 0: route already in table
