Okay, so you're using a stock 4.4 kernel.  Good!  But we still don't know:
1) what your route table looks like.  What's the output of
  netstat -nr -finet
   ?
2) what the state of the loopback interface is.  On a correctly operating
   system, bringing up lo0 with the 127.0.0.1 IP gives you the correct route.
   So what's the output of
  ifconfig lo0
   ?

For comparison, booting my laptop into single-user mode I see this:

# fsck -p
...
# mount /usr
# ifconfig lo0
lo0: flags=8008LOOPBACK,MULTICAST mtu 33204
priority: 0
groups: lo
# netstat -nrfinet
Routing tables
# ifconfig lo0 inet 127.0.0.1
# netstat -nrfinet
Routing tables

Internet:
DestinationGatewayFlags   Refs  Use   Mtu  Prio Iface
127.0.0.1  127.0.0.1  UH 00 33204 4 lo0
# ifconfig lo0
lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 33204
priority: 0
groups: lo
inet 127.0.0.1 netmask 0xff00
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3

Note that the route added by bringing up lo0 is *NOT* the same as one
generated by the 'route' command you mentioned: the flags are different.

That suggests item #3 for you to try:
3) boot your box into single-user mode, do the same steps above and compare
   the output.

If you see similar output when you boot single-user, but the route vanishes
when you go multiuser, then you need to check your network config files and
start scripts for a possible guilty 'route' invocation or anything
else that could
be dropping that route: /etc/hostname.*, /etc/bridgename.*, and
/etc/rc*.local.

You don't happen to run bgpd or ospfd or some other routing daemon, do you?

Missing route for localhost

2009-01-17 Thread Michael Mäder 

Hello

I am using 4.4 (updated from 4.3) and have a problem with the localhost.

Trying to ping localhost gives my an error: host unreachable

Comparing with a fresh BSD installation I remarked that the following  
routing entry is missing:


route add -inet 127.0.0.1/32 127.0.0.1

Even after a reboot this is missing. Does anybody has a hint, why?

Thanks
 Mike

It's obvious from your dmesg that, umm, nevermind.

It's clear from the steps you took when updating that, uh, nope.

That route is added automatically when the loopback address is
initially assigned its address and brought up.

Since you didn't give any actual data, I'll guess that your update
procedure was broken such that your kernel and userland don't match,
probably giving you a -current kernel with -stable userland.  Pick one
and use it for both.
