How to Prevent WICD Overwriting /etc/resolv.conf

tronayne · 12-19-2013, 08:36 AM

Got this lap top. It's configured (like all my servers) with fixed-IP (it's normally connected with Ethernet). When it's "on the road," it's connected with wi-fi and that blasted thing overwrites /etc/resolv.conf.

I have these un-commented in /etc/rc.d/rc.inet1.conf:

Code:

DHCP_KEEPRESOLV[4]="yes"       # If you don't want /etc/resolv.conf overwritten
DHCP_KEEPNTP[4]="yes"          # If you don't want ntp.conf overwritten

Is there some setting I've missed somewhere? I keep a /etc/resolv.conf.bak that I copy over /etc/resolv.conf to get the DNS server addresses after connecting with WICD (and the file gets wiped) which is annoying but not fatal and I'd really like to stop having to do that.

Any hints? Some setting I've missed somewhere or other?

I had this same problem with /etc/resolv.conf and /etc/hosts. There probably is (or should be) a way to configure it to not overwrite these files, but I gave up and ended up just marking them as immutable:

Code:

chattr +i /etc/resolv.conf

If anyone has a better way of doing it, please share!

The change in your /etc/resolv.conf is made by dhcpcd which gets invoked by wicd. If you want to keep your own resolv.conf, simply add "nohook resolv.conf" to /etc/dhcpcd.conf. If you'd rather prefer having a customized resolv.conf, have a look at /lib/dhcpcd and the dhcpcd man pages.
