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?
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
My Internet connection runs slow and jerky, but can be fixed by using the Google public nameservers instead of the default one in this file. Problem is, the changes keep being reverted, even when I chmoded the file to have read-only permissions by everyone.
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'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it notices that I had another process modify it (dhcpcd to be exact) and it just won't overwrite it, resulting in an out of date DNS server to be used.
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:
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 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)?
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 tried to setup a dyndns, and ever since I tried to get that setup, I can't access my webmin, or access /etc/hosts/resolv.conf. But I can still access my samba shares I had created before this happened.
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'm having problems with my resolv.conf file. Every time I reboot my computer it goes blank and I have to re-type it before I can get on the network. How do I prevent it from being overwritten?
I am using KVPNC (recommended by the VPN owner) on Ubuntu 9.10 using my Universities direct Ethernet connection.
I have downloaded all the .ovpn scripts to a directory. I have downloaded KVPNC from the repository (apparently for 9.10 you do not download from the KVPNC website).
I then use sudo kvpnc and select a server (since there are many based on the .ovpn files).I click connect and the script works and tells me I have a connection. See below for an example. All appears to work.
But when I actually load any Internet program e.g. Firefox it cannot find a website.This happens for all servers which have different locations around the world.When I disconnect KVPNC I still have no access. I have to remove the Ethernet cable before it works again.
debug: Connect try requested, profile: Stockholm, type: OpenVPN debug: openvpn: /usr/sbin/openvpn debug: Support for TUN/TAP found (compiled into kernel or kernel module already loaded). debug: Default interface: "eth0". debug: IP address of default interface: "my IP address". code....
I realise there are errors e.g. the /etc/resolv.conf must be a symlink but have tried doing this and still have exactly the same issues.
I'm using 9.10 Ubuntu Karmic 64-bit (but same thing happens on my 32 bit VM on same PC).
My /etc/resolf/conf file is not updated with DNS information on first boot. The DNS information is in the /etc/network/interfaces file.
The trick I have to do every time I reboot the PC is:
Code: sudo ifdown eth0 && sudo ifup eth0
First off, why? Second how can I resolve this issue?
I have three NICs eth0 and 1 are normal LANs connected to the internet, but I choose eth0 as the primary. eth2 is a local private one. the DNS information from eth0 should be in the resolv.conf file but isn't. The file is empty at bootup, except for some comments instructing me not to edit this. After running the above sudo commands the file is properly updated and internet works.
Here's my /etc/network/interfaces file's contents:
Code: auto lo iface lo inet loopback auto eth0 #iface eth0 inet dhcp
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.
I am trying to edit my /etc/resolv.conf file while under root. After saving the changes and reboot my computer, file has not changed. I read a thread on chattr and lsattr on this fourm.(see link below) I ran in terminal lsattr /etc/resolv.conf and got the following results:-----------------e- /etc/resolv.confWhat does the dashes and e mean? I thought I would get ----ia------------ /etc/resolv.conf instead, as shown in the link. What am I doing wrong?
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:
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.
When I boot my computer (Ubuntu 9.10) /etc/resolv.conf is written as:# Generated by Connection Managernameserver 10.33.8.11 10.33.4.136However, if I try to do anything from the command line, I get an error like:host: parse of /etc/resolv.conf failedI then need to edit /etc/resolv.conf to:
# Generated by Connection Manager nameserver 10.33.8.11 nameserver 10.33.4.136
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
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:
I'm having an issue with resolv.conf being empty (apart from the resolvconf header) upon first login. I am assigned a DHCP lease fine, it also appears that DNS works briefly as all my NFS file shares seem to be working ok and they have name rather than an IP address in /etc/fstab. I have to manually re establish my lease by using the Network Manager panel each time I first login.
I use wvdial and a 3G modem to connect to the network. On the same host I also run bind9 which is authorative for my local network.The problem is that when wvdial connects, it overwrites /etc/resolv.conf, which means that DNS lookups on that host no longer get made to localhost (as specified by the original resolv.conf file) and end up at the local instance of bind which is authorative for in-house hostnames, but end up with the ISP who doesn't know my in-house host names.The local DNS forwards to the ISP, so the ISP's DNS'es are not required in resolv.conf.How can I prevent wvdial from overwriting /etc/resolv.conf?Removing write privileges from /etc/resolv.conf did not work.
