New dhcpcd doesnt support "-R"??

FLCLFan · 2008-10-15 05:55:47

Well today I updated my dhcpcd to version 4 from the repos and now when I boot, it fails saying it doesnt know what "R" is and I have no internet until I manually call up dhcpcd.

But, I use Opendns so I have been using

DHCPCD_ARGS="-R -t 30 -h $HOSTNAME"

in my '/etc/conf.d/dhcpcd' so it doesnt overwrite my '/etc/resolv.conf' with the opendns nameservers in it.

Now, what do I do now?

man dhcpcd

−C, −‐nohook script
Don't run this hook script. Matches full name, or prefixed with
2 numbers optionally ending with .sh.
So to stop dhcpcd from touching your DNS or MTU settings you
would do:‐
dhcpcd ‐C resolv.conf ‐C mtu eth0

in your case DHCPCD_ARGS="-t 30 -h $HOSTNAME -C resolv.conf"

I noticed the .head and .tail entries in /etc/resolv.conf and thus I created a file /etc/resolv.conf.head (Alongside the existing resolv.conf.auto, as it has been mentioned) and entered my nameserver <IP> stuff in that.

It automatically pastes the same into the /etc/resolv.conf when started from then on. The -L option perhaps does this thing, I found that alone to be new.

That works. Thanks

Updated the wiki with it too.

Does not work here. This survives a /etc/rc.d/network restart, but it still overwrites resolv.conf on restart of adsl connection.

I have that .head file.. that never worked for me.. with or without -L option didnt matter

bash-3.2# cat /etc/conf.d/dhcpcd

bash-3.2# cat /etc/resolv.conf

*edit* the very same line works for someone in #archlinux o_O

right.. i simply changed my adsl setup to NOT receive any dns servers. Now it works fine with the -C option
