Hello Folks,
Noticed a strange issue with the creation / update of
/etc/resolv.conf. The details of the system that I noticed the issue
on is:
Version : FreeBSD 8.0
Patch level: not patched
Uname: FreeBSD shastry.eudaemonicsystems.net 8.0-RELEASE FreeBSD
8.0-RELEASE #0: Thu Sep 29 22:37:51 IST 2011
r...@shastry.bhuta.in:/usr/obj/usr/src/sys/SHASTRY i386
I generally have a static IP 192.168.98.6 (via rc.conf) for my
Beastie. The contents of my /etc/resolv.conf is as follows:
domain eudaemonicsystems.net
nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 4.2.2.2
No matter how many times I reboot the system, the resolv.conf does not
get overwritten when configured with a static IP.
I modified the /etc/rc.conf to have the flag:
ifconfig_re0="DHCP"
The next reboot of the system caused the /etc/resolv.conf to be
overwritten with the following contents:
nameserver 192.168.98.4
I was baffled with this behaviour and checked /etc/rc.d/resolv script
and there was no reason as to why "[ ! -e /etc/resolv.conf]" should
fail at any given instance. Out of curiosity executed "/bin/kenv
dhcp.domain-name" which returned with the info: kenv: unable to get
dhcp.domain-name. Would it be fair to assume that /etc/rc.d/resolv
not to cause the issue?
What is causing this behaviour? Have I missed something?
Had a look at network-dhcp.html, and found /etc/dhclient.conf to be
empty on my system.
Digging further, was looking at the scripts under /etc/rc.d, found
/etc/rc.d/named to be another script creating the /etc/resolv.conf and
this was in the routine named_precmd(). I have not enabled
'named_enable' flag in /etc/rc.conf, while it is commented; by
default; in /etc/defaults/rc.conf file.
From my /etc/dhclient.conf:
interface "lagg0" {
send dhcp-lease-time 3600;
prepend domain-name-servers 127.0.0.1, 4.4.4.4, 8.8.8.8;
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers;
require subnet-mask, domain-name-servers;
}
And result is /etc/resolv.conf:
# Generated by resolvconf
nameserver 127.0.0.1
nameserver 4.4.4.4
nameserver 8.8.8.8
nameserver 192.168.1.1
