Dhcpcd overriding /etc/resolv.conf, 'nohook resolv.conf' [solved]

hello.
I set dhcpcd not to override the /etc/resolv.conf file:
[root@ jenia]# cat /etc/dhcpcd.conf
# A hook script is provided to lookup the hostname if not set by the DHCP
# server, but it should not be run by default.
nohook lookup-hostname
noipv4ll
nohook resolv.conf <----------------------------------------------------------------------------
However, this has no effect:
[root@ jenia]# cat /etc/resolv.conf
domain members.linode.com
nameserver 72.14.179.5
nameserver 72.14.188.5
nameserver 2600:3c00::2
nameserver 2600:3c00::3
options rotate
[root@ jenia]# systemctl start [email protected]
[root@ jenia]# cat /etc/resolv.conf
# This file is managed by systemd-resolved(8). Do not edit.
# Third party programs must not access this file directly, but
# only through the symlink at /etc/resolv.conf. To manage
# resolv.conf(5) in a different way, replace the symlink by a
# static file or a different symlink.
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 2001:4860:4860::8888
# Too many DNS servers configured, the following entries may be ignored
nameserver 2001:4860:4860::8844
As you can see dhcpcd ovveride the /etc/resolv.conf file.
How can I avoid this? How can I change the file and make the changes permanent.
Thanks in advance.

yes. exactly. i removed and used a text editor to make the necessary changes to a file of the same name (/etc/resolv.conf).
now the changes remained.
thanks.

Dhcpcd and /etc/resolv.conf

How can one prevent dhcpcd from modifying /etc/resolve.conf?
Or can one prepend static options before it's own ones?
(I'de like to have my own search and nameserver entry.)

Yes. Add it to /etc/conf.d/dhcpcd in DHCPCD_ARGS.

Override CFLAGS and CXFLAGS from /etc/makepkg.conf [solved]

This might be a stupid question, but here goes: if I redefine variables such as CFLAGS and CXXFLAGS from within a PKGBUILD, any subsequent make would use the new ones rather than the ones defined in /etc/makepkg.conf ...right? I'm assuming that makepkg reads them once when the user invokes it.
Thanks.

Thanks. I looked at /usr/bin/makepkg and I believe this is the case, but I don't know of a way to check after I compile them. Is there some place I can look within the final NAME.tar.xz to see which CFLAGS were used? (Again, I think the answer here is "no").

[SOLVED] How Can I Stop DHCPCD from Overwriting my /etc/resolv.conf...

Hey guys,
For some unknown reason /etc/dhcpcd.conf continually overwrites my /etc/resolv.conf file, eventhough I set the "nohook resolv.conf" hook in /etc/dhcpcd.conf.
This is screwing up my DNS and intermittently creating connection problems. Any of you guys know why the hook is not taking effect or how I can stop dhcpcd from overwritting this file?
Thanks

I changed my DNS to the Google one (8.8.8.8 or something). That's in "resolv.conf", isn't it? I remember editing some OTHER configuration file, which is then read to create the "resolve.conf" file. There it is, in that link to the wiki, under "Use resolv.conf.head". Does that help you do what you want to do?
There's three techniques at the wiki link, the nohook one, the resolv.conf.head one and the write-protection attribute.

Dhcpcd overrides resolv.conf from vpnc

As soon dhcpcd renews the lease the resolv.conf from the vpnc gets overridden. At the moment my workaround is to copy periodically the resolv.conf.
Is there a proper solution? Have I missed a configuration parameter?
The dhcpcd is startet in this way:
dhcpcd -b -q -t 0 wlan0

I just solved this issue and I wanted to share my solution in case anyone else runs into this problem. Hopefully there isn't a rule against replying to month-old threads =P
How to make dhcpcd and vpnc work together:
1) Install openresolv. This package provides resolvconf, which helps coordinate modifications to /etc/resolv.conf. With resolvconf, dhcpcd and vpnc will no longer overwrite each other's changes to /etc/resolv.conf
2) Modify /etc/vpnc/vpnc-script to look for resolvconf at /usr/sbin/resolvconf instead of /sbin/resolvconf
3) Do not modify /usr/lib/dhcpcd/dhcpcd-hooks/20-resolv.conf. This hook will work with resolvconf without any modifications
Hopefully this will be helpful to someone

/etc/resolv.conf between netctl profile switches

Hi, all.
I use same laptop at home and in my office. Network is managed by netct. At home I connect using a profile generated by wifi-menu, in the office — plain ethernet-dhcp profile form examples folder.
With both connections nameservers are obtained via dhcp.
The issue is that after switching from office ethernet-dhcp to my home wi-fi netctl profile, /etc/resolve.conf retains nameserver and domain entries from the office connection. My home's nameserver entry gets appended to the end of the resolv.conf file. This, of course, causes unacceptable delays when resolving domain names, so I have to edit /etc/resolve.conf manually every time I've been using that office's connection.
I'm wondering whether there is something wrong with my setup.
Profiles are nothing special, as I said:
Description='Automatically generated profile by wifi-menu'
Interface=wlp3s0
Connection=wireless
Security=wpa
ESSID=my_ssid
IP=dhcp
Key=my_passwd
Description='A dhcp ethernet connection'
Interface=enp0s25
Connection=ethernet
IP=dhcp
DHCPClient='dhcpcd'
Please, help me to resolve that issue. Feel free to ask for more details if needed.
Thanks in advance for help.

2branch,
I switch them with netctl switch-to command, which is incorrect, as I understand now.
Important notice is that I unplug ethernet cord first, and then I perform a switch.
Also I tried disabling ethernet-dhcp explicitly after switching to wlp3s0 — not helped.
I checked /run/resolvconf/interfaces, and found that enp0s25 is missing. Instead, I have tun0, which contains problematic entries.

[solved]how to stop /etc/resolv.conf keeps being overwritten ???

no matter how many times to change the content, it keeps like that:
# Generated by dhcpcd from eth0
# /etc/resolv.conf.head can replace this line
nameserver 192.168.8.1
# /etc/resolv.conf.tail can replace this line
so i can't add nameserver in it
Last edited by tempo (2010-01-14 15:01:35)

The clue is in the message, use a file called resolv.conf.head to add a nameserver to the top and resolv.conf.tail to add it to the bottom.
It's being overwritten because you are using dhcpcd to auto configure your network settings.

[SOLVED] /etc/resolv.conf vs. the DNS field in netctl profiles

I'm a bit confused about the current role of /etc/resolv.conf. The Netctl profile documentation has a DNS field, so has /etc/resolv.conf become functionally obsolete when using netctl? Or is /etc/resolv.conf still useful when you have multiple interfaces, as it specifies DNS servers for all interfaces?

How to regenerate /private/etc/resolv.conf

Folks,
I use my Snow Leopard macbook pro on multiple networks and recently made the mistake of editing the /private/etc/resolv.conf to add a search path. So now the file looks like so:
# Mac OS X Notice
# This file is not used by the host name and address resolution
# or the DNS query routing mechanisms used by most processes on
# this Mac OS X system.
# This file is automatically generated.
search mydomain.com
nameserver 192.168.2.2
Edit: The file doesn't appear properly but the first few lines are all commented out using #.
I hadn't paid much attention to this file before now so I'm not sure whether this file keeps getting re-generated for every network (e.g. by dhcpd) but it's certainly not being re-generated any more.
I heavily use the "host" command to lookup hostnames which is one of the few commands that uses the /private/etc/resolv.conf file instead of SL's own DNS. I'm definitely feeling pain at this time. Any ideas on how I can get this file to be re-generated again?
FWIW, I repaired permissions on the disk using "Disk Utility" and the permissions look like:
lrwxr-xr-x@ 1 root wheel 11 Dec 1 22:46 /etc -> private/etc
-rwxr-xr-x 1 root wheel 261 Dec 14 21:26 /etc/resolv.conf
-rwxr-xr-x 1 root wheel 261 Dec 14 21:26 /private/etc/resolv.conf
Thoughts?

Depending on your editor, it is possible that the editor created a new file uniquely named file, then renamed the uniquely named file to the original name, causing the file system to delete the current directory entry (the symlink). This would have the effect of deleting the symlink and replacing it with a real file.
Another possibility is that the orignal symlink was changed to resolv.bak (or similar name). if you edited multiple times with an editor that does this, the 2nd editing session would have removed the symlink from the system, and left only regular files.

Who writes /etc/resolv.conf?

Someone is writing the "domain" configuration directive to /etc/resolv.conf on boot. I suspected DHCP, so cleared the domain field at the DHCP server that serves the Solaris 10 computer in question, but /etc/resolv.conf is still picking up the domain name from somewhere. Who does this and where does the information come from?
Alan Feldstein
Cosmic Horizon
http://www.alanfeldstein.com/

Observed that ".alanfeldstein.com" was being appended to each inquiry (as suggested by result) of the following form:
getent hosts yahoo.comThis is incorrect. alanfeldstein.com is hosted by a service provider, not here. That is, it's not on the path from here to DNS. If a domain must be appended to a name lookup handled by DNS, that of my ISP (earthlink.net), or none at all, would be more appropriate. So I removed
domain alanfeldstein.comfrom /etc/resolv.conf. However, it reappeared after reboot. I theorized that /etc/resolv.conf was written with data from my DHCP server, so I emptied the domain field there.
Still, /etc/resolv.conf was being automatically written with the same date at boot time. This question can remain open (with reduced Dukes) because I'm still curious about where that data was coming from after being cleared from the DCHP server's domain field.
I did find that specifying earthlink.net at the DHCP server caused
domain earthlink.netto appear in /etc/resolv.conf of my NIS server, which forwards non-local names to DNS on behalf of my NIS clients. And that fixes the problem I was having (i.e. inability to lookup non-local names from NIS clients).

I never setup any dhcp client configuration before, but each time the VM is rebooted or started it seems that the /etc/resolv.conf always gets overwritten again.
However, in Server 1, somehow the dhcp client is working and getting the right DNS server IP address.
What I want to achieve for the Server 2 is like the one in the Server 1 where the nameserver I got from the ISP is also configured there.
That will made it easier if I need to download just a small file from the internet.
Other than that, I also wanted to understand what other configuration that could affect this /etc/resolve.conf file gets overwritten, which configuration and how to configure it.
Thanks in advance for your help in advance.

Hi Dude!,
To make it simpler, I can simply delete those interfaces (eth0, eth1, eth2, & eth3) right now and left with eth4 which I think can be directed to the actual question I was asking.
So here's the result of ipconfig on my host:
Ethernet adapter Local Area Connection:
   Connection-specific DNS Suffix . :
   Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller
   Physical Address. . . . . . . . . : 00-90-F5-CC-F9-DB
   DHCP Enabled. . . . . . . . . . . : No
   Autoconfiguration Enabled . . . . : Yes
   IPv4 Address. . . . . . . . . . . : 192.168.1.5(Preferred)
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1
   DNS Servers . . . . . . . . . . . : 192.168.1.1
                                       103.11.48.126
   NetBIOS over Tcpip. . . . . . . . : Enabled
As you can see from that result, if you compare the Server 1 and Server 2, the /etc/resolv.conf from Server 1 managed to get that 103.11.48.126, whereas the one in the Server 2 couldn't.
This is exactly what I'm trying to resolve.
Does this make any sense to you?
Just forget about the other interfaces.
Thank you,
Adhika

Oracle Linux 6.6 I tried to edit the /etc/resplv.conf file on nano, gedit and VI but the result doesn't appear on the file when I cat it

Hi ! do you mean the file /etc/resolv.conf ? This file should be by default in the /etc/ diretory and contains the dns-name resolutions. http://linux.die.net/man/5/resolv.conf http://www.tldp.org/LDP/nag/node84.html http://en.wikipedia.org/wiki/Resolv.conf

Settings in /etc/sysctl.conf overwritten [SOLVED]

I added a new line to /etc/sysctl.conf setting the vm.dirty_ratio to 3 (line is simply `vm.dirty_ratio = 3`). I can invoke it by running `sysctl -p` so I know the syntax is correct. This setting is however not loaded upon a reboot. The systemd-sysctl.service is however kicked off just fine and completes without errors. I have also tried removing the line from /etc/sysctl.conf and placing it in /etc/sysctl.d/dirty.conf but again, it is not honored at boot. What am I doing wrong?
EDIT: The solution is in post #31 - acknowledgement to chp for pointing me to it. Note that I also changed to topic to a more relevant one.

Guess I'm stumped. I just spun up an Arch VM, pasted in the /etc/sysctl.conf below and reboot it. All the settings in the file in the VM are applied. If Leonid's guess that something is overriding these values on my workstation, I would like to figure out what it is and shut it down. To keep things simple, I booted into the stock ARCH kernel; here are the services I have active:

/etc/logadm.conf gets rewritten bug

I think I found a race condition in logadm that makes can corrupt the conf file. Firstly, let me say that any utility that expects to update a timestamp in a running conf file is asking for trouble. The utility should be "selfhealing" and the conf file should be untouchable with a separate status/timestamp file.
So I have a system running :
SunOS XXXXXX 5.9 Generic_118558-27 sun4u sparc SUNW,Sun-Fire
At the same cron time, it calls:
0 3 * * * /usr/sbin/logadm
and
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /bin/rm /var/adm/pacct.[0-9]*;/usr/lib/acct/turnacct switch
At 3 am, both would be called. "turnacct switch" calls "logadm -p now /var/adm/pacct".
There must be insufficient locking or no locking because the result on my system is only the pacct record in /etc/logadm.conf; the previous standard entries are all lost in /etc/logadm.conf.
Result in /etc/logadm.conf:
/var/adm/pacct -P 'Fri Jul 6 15:50:00 2007'
The fix is to offset the running of logadm by a minute or two in cron. The real fix would be to rewrite with correct file locking.

also, could i suggest adding entries for opendns to your /etc/resolv.conf.tail after your local one?
domain myhome.westell.com
nameserver 192.168.1.1
nameserver 208.67.222.222 #opendns
nameserver 208.67.220.220 #opendns
works nicely as a backup if your somewhere with a dodgy dns etc
Yep, I just tried and it works fine when I use nslookup but web browser and ping still dont work. I can use googles ip 74.125.53.100 and everything works, but not the domain name. As for opendns Id really just like to get my standard dns to work for now, I know it should work because I use it on all the other computers plus it works with dhcp. After I figure out what Im doing and whats going wrong Im probably going to setup my router to use opendns.
[tj@arch ~]$ nslookup google.com 192.168.1.1
Server: 192.168.1.1
Address: 192.168.1.1#53
Non-authoritative answer:
Name: google.com
Address: 74.125.53.100
Name: google.com
Address: 74.125.67.100
Name: google.com
Address: 74.125.45.100
[tj@arch ~]$
I still havn't got around to seeing if I can get it to work with netcfg, it was late last night and I fell asleep. Ill try it now and post back with the results.

Dhcpcd overriding /etc/resolv.conf, 'nohook resolv.conf' [solved]
