OpenSUSE Network :: NetworkManager Doesn't Update Resolv.conf
Apr 20, 2011
In previous openSUSE versions I was using WICD as network manager. I upgraded my openSUSE to 11.4 and resolved give a try to the NetworkManager. I can get network connection, but the dhcp doesn't update the /etc/resolv.conf, so I can't navigate because the dns isnt set.
I tried to reinstall all related packages (dhcp, dns and networkmanager) without success.
If I run dhcpcd the resolv.conf get updated, but dhclient doesn't do the same. It seems that's a dhclient script issues, but I don't know how to test.

I'm having some trouble with my networkmanager on openSuse 11.2. I want it to get the DNS Server from DHCP, but it notices that I had another process modify it (dhcpcd to be exact) and it just won't overwrite it, resulting in an out of date DNS server to be used.

I just installed F10 from a Live download iso on a Sony VAIO laptop with an Intel PRO/Wireless LAN2100 3B Mini PCI Adapter. The linux driver is ipw2100 and functions without problems.
After the install I accepted the update downloads offer and downloaded somewhere around 170 updates. The kernel version is 2.6.27.19-170.2.35.fc10.i686.
I am using a Linksys WRT55AG as a DHCP server. Using NetworkManger it assigns IP addresses without incident.
My problem is that I can't get name resolution to function without manual intervention.
I can ping other wireless nodes on my network and the response to $ dig -q www.yahoo.com is: ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 30153
The /etc/resolv.conf file contains no entry for 'nameserver=' and if I manually edit /etc/resolv.conf, it is overwritten on reboot or restarting the NetworkManager service. I am aware of /etc/sysconfig/networking/profiles/default/resolv.conf.
Additionally, in the var/log/messages file I can see that NetworkManager makes links between /etc/resolv.conf and the default version.
However, after either rebooting or restarting the NetworkManager service, if I manually enter a DNS address 192.168.1.1 (my wireless router) under the DNS tab of the system-config-network 1.5.95 application. This address does not persist after either rebooting or restarting NetworkManager.
If I disable NetworkManager, I can't get the WRT55AG to assign the wilreless adapter an IP address.
So the bottom line and my question is what do I need to do in order to simply boot and have wireless connectivity?
To what file does system-config-network 1.5.95 write the DNS address entered from it's GUI?

This continues a thread started in the applications forum:mc hangs temporarily when network is downmc (Midnight Commander) hangs on my desktop but not on my laptop. When I compared desktop and laptop configurations, I found the following differences:
/etc/hosts files:
Code:
Laptop: 127.0.0.2 linux-4xt8.site, linux-4xt8

I cannot seem to find where the conf files for NetworkManager are stored in suse 11.3. I want to manually edit my IP address without using the gui.

My network works before but now it has follow issue, when I ping google.com, I got Quote:
ping: unknown host google.com but my network still works partially because I can still connect to a DNS listed in my /etc/resolv.conf to get host google.com's ip adress by Quote:
host -t a google.com ip.of.one.dns and then I ping the returned IP result 66.249.89.104, the ping works fine. the issue is that I can't connect to Internet, what I can remember is that I ever removed /etc/resolv.conf and this file was created again by network-manager, and I already verified the two dns IPs listed in the resolv.conf are both correct and works fine with command host.

We recently moved all our Red Hat Linux machines from NIS to LDAP and we're seeing some issues with name resolution.
One thing I should mention is that DNS (the first nameserver in resolv.conf)is being used by LDAP for name resolution.
Now our resolv.conf file has always looked like this.
Search domainname.com
Search domainname2.com
Nameserver xx.xx.xx.xx
Nameserver xx.xx.xx.xxx
The problem is that the above resolv.conf file doesnt work anymore. The only way that our workstations get name resolution is by commenting out the second and forth lines, which happen to be our secondary DNS. This has got me confused because why would resolv.conf be broken by having a secondary nameserver and search path? Shouldnt it just use the first nameserver unless it fails to resolve? Almost seems like just having the secondary in the file breaks name resolution. I cant ping local hosts or anything on the internet unless I do this:
Search domainname.com
#Search domainname2.com
Nameserver xx.xx.xx.xx
#Nameserver xx.xx.xx.xxx

I find it very frustrating that documentation suggests using PEERDNS=no in /etc/sysconfig/network-scripts/ ifcfg-eth0 in order to override resolv.conf information only to find out that both NM and network init scripts ignore DNS1, DNS2 and DOMAIN settings.So my question is how do I correctly configure resolv.conf settings that will persistently override dhcp information on a F12 system that has NM removed and uses the network service scripts?

My resolv.conf states:
No nameservers found; Try putting DNS servers into your ifcfg files in /etc/sysconfig/network-scripts like so: [...]
After running wvdial. I suppose I have to create a file ifcfg-ppp0, but what does it have to contain in order to automatically grep the DNS servers from wvdial?
In Ubuntu, it works just fine, just that I don't have an Ubuntu installation anymore.

I have been trying to follow this guide for dnssec http://wiki.debian.org/DNSSEC in which at the very last it gives that you should change the value in /etc/resolv.conf to 127.0.0.1 Now in mine, network-manager overwrites the values. Is there a way to stop network-manager from overwriting the values in /etc/resolv.conf ?seems the simplest is to write-protect it. chattr +i /etc/resolv.conf

The local DNS server is slow, so I added the openDNS servers to /etc/dhcp3/dhclient.conf. But Network manager keeps appending the local DNS server to resolv.conf. I need to pick up a DHCP address but how to stop it changing DNS servers?

My ethernet controller is configured as such:
My /etc/resolv.conf file is normally just set up to use Google's public DNS:
When I connect to the network at the university library, it totally overwrites my /etc/resolv.conf file to something like:
This is pretty annoying, so I tried comprimising by making a file with the school's domain and search entries plus the Google nameservers, then revoking write permission on the file. However, I couldn't access any domain name with this config on their network, so I reverted to using their nameservers. I keep all the school's entries commented out when I connect to my home network.
My ultimate question is what is actually overwriting the file? I suspect that my connecting through DHCP is responsible. Whatever it is, I'm pretty annoyed that no back up file was created.

I use my laptop both at home and at my job. At home it gives me the correct search line.
But when I am at the office I only get 1 search entry while if you boot in windows it gives you 3
(for example):
So this should be in /etc/resolv.conf search domain domain.com my.domain.com
It seems that this is not passed by the (Windows) dhcp server (Active Directory).
Is there any way that linux can detect depending on the network it is in that there are a few search domains added(for example like resolvconf does with ppp tunnels)?

I've had 11.4/KDE working pretty well on dual boot Asus G73SW for a few weeks now. Only issues were the FN-* functions that control keyboard lights and whatnot but no biggie since the essential worked.The last couple of days the update notification was indicating 1,201 updates to be made. Yeah it seemed extreme but I googled around and checked the forums and there was nothing related. I figured I might be missing some packages since I installed from the live KDE CD (still 1202 updates!!!???). So I updated. Big mistake!!!!! Ever since NetworkManager cannot connect to the internet, be it wired or wireless.
Initially it could not even see my home network but it picked it up after I removed the plasmoid from the panel and reinstalled it. However it doesn't respond when I click the network icon and still no connection.I managed to get eth0 working with ifup but not wifi. The last part of network manager log file is quoted below. I can send the whole thing to whoever is interested. I can't make sense of it but maybe someone on the forums can.
Code:

My Debian workstation is on a predominantly Windows network. It is resolving internet addresses (i.e. www.google.com, etc) just fine. However it's not resolving any of the address of machines on the local network and the windows machines do not resolve the linux machines address either. All machines (linux and windows) can access each other just fine via direct IP reference.
My /etc/resolv.conf file has the following IP addresses listed:
127.0.0.1
10.1.1.111
10.1.3.4
10.1.1.111 is a netgear VPN/router that is the primary router for the LAN and maintains a VPN to a remote office 10.1.3.4 is the IP address of the Windows Primary Domain control on which the DNS server is running. That server is at the remote office. The system acts like it is completely ignoring anything I put in the resolv.conf file. From the linux X server I'm using "Network Setting" utility to make changes to the network configuration. This appears to work fine for things like switch between DHCP and static IP.

I use Fedora 13 (minimal installation), ISC DHCP server 4.1.1-P1. I'm running Fedora 13 too on a separate machine (minimal installation) with ISC DHCPclient 4.1.1-P1. My goal is to do some IPv6 testing. When I use the DHCP client manually (dhclient -6 -timeout 5 -d -v eth0), the client retrieves and installs a dynamically assigned IPv6 address.
Additionally, the client gets 1 DNS resolver address and 1 DNS search list. The resolver address and DNS search list always get written into /etc/resolv.conf. Perfect, exactly what I need. But when I do a "service network restart" or restart my system (which should trigger the same, as far as I understood), the DNS resolver addr and the search list get written into /etc/resolv.conf.save and the /etc/resolv.conf stays as before. How can I change this behavior? I don't need the .save file, I just want to have /etc/resolv.conf replaced by the latest DNS information.

I'm setting up virtual dev environments and I want the hostname.domain to be something specific, eg- "barney.local". However my /etc/resolv.conf file keeps getting nuked because i'm using DHCP. I placed this into my dhclient.conf:
supersede domain-name "localhost"
supersede host-name "barney"
but it didn't help. I'm not sure where I'm going wrong. How can I still use DHCP but configure that virtual environment to see itself as barney.local?

How can I keep /etc/resolv.conf static ... as in preventing it from being changed by the network manager ... without actually disabling the network manager (so wireless users can get their wireless setup that includes IP address, but leave the resolver configuration as is)?

I need help figuring out why my resolv.conf keeps changing to this, causing me to not be able to access the outside internet and only the local network.I thought I fixed it by getting rid of the loopback interface and adding in the eth0 interface in /etc/network/interfaces URl...And then things would work temporarily, and eventually the nameserver in resolv.conf would get reverted again.

I am using kubuntu 9.10 64-bit on AMD M500 machine i removed networkmanager (because i had frequent disconnect) and installed wicd but the /etc/resolv.conf had a comment on top which says that it is to be configured by networkmanager (still) I put the DNS in there manually and it works What to put in there so that it uses DHCP ? Maybe its set to be not written by anyone other than networkmanager ??

As you may well be aware the resolv.conf search appears to be limited to 6 domains. I need 7 One thing I noticed is that if you run nslookup on a short name that is in the 7th search it does work but ssh does not. I'm guessing that nslookup is actually reading the whole file and isn't limited.

I am having a situation where I do not have DNS server (the person who has that is not me) for a few websites which are running on a reverse proxy. I recently after having a long trouble shooting hours found that my proxy pass entries look as follows
Code:
ProxyPass /app1 http://192.168.1.3:8080/app1
ProxyPass / http://192.168.1.3
ProxyPassReverse /app1 http://192.168.1.3:8080/app1
ProxyPassReverse / http://192.168.1.3
If I use the entries as above then some one from internet is able to access the sites.But from within LAN people are unable to access it.
How ever if I use
Code:
ProxyPass /app1 http://site1.myserver.com:8080/app1
ProxyPass / http://site1.myserver.com
ProxyPassReverse /app1 http://site1.myserver.com:8080/app1
ProxyPassReverse / http://site1.myserver.com
then things work on LAN but from internet it is not accessible.What can be a solution in this case will putting things in resolv.conf do?

As I understand it, /etc/resolv.conf is rewritten at boot time by NetworkManager (a script?)I have a problem in the order the nameserver entries are written by my system (F13). This is:
Code:
nameserver 192.168.1.1
nameserver xxx.233.0.4
