Debian Configuration :: Preferred Resolv.conf Fix For Bind9?

Dec 30, 2010

I "fixed" my Lenny home server bind9 configuration because my resolv.conf was always overwritten loosing configuration. The fix involved adding the following to /etc/resolvconf.resolv.conf.d.base.

##base file at /etc/resolveconf/resolveconf.d/base
nameserver 127.0.0.1
nameserver 192.168.1.4

Debian Configuration :: Can't Get DNS Client To Use What's In Resolv.conf

Jun 18, 2010

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.

Debian :: Configuration - Domain Name- Host Name - Resolv.conf Areas

Feb 6, 2009

I installed debian etch, it runs and does connect to the internet fine through a linksys router...the linksys router is connected to my cable modem...now..

I just registered for a domain name (ex. mydomainname.org) with Verio....this is where I am stuck.

I installed apache 2, a web server, file server (all seem to work) I need to know what files I need to configure to have my machine actually BE that domain name.

Ex. my linksys DHCP IP addresses, the linksys gets an IP from the cable modem...my yquestion is ONCE I register a domain name with verio...how do I configure my end so it "knows" I am that respective domain name...I think I need to configure the following, but knot sure how to do it: resolv.conf, hosts, and interface?

Debian Configuration :: Public Network Overwrites /etc/resolv.conf

Dec 10, 2010

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.

Debian Configuration :: Networking - Netinst CD - Internet Connection Only Works After Edit The Interfaces And Resolv.conf Files Manually

Aug 3, 2010

I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.

Debian Configuration :: Is There Preferred / Better Method For Setting Up Alsa?

Apr 30, 2011

Would like to know the best way (or the pros and cons of different ways) to set up Alsa. I did a search for information on how to setup alsa on my system. I found a lot of out-of-date information even on the alsa wiki. What I did finally locate was two different methods for setup, both seemed somewhat up-to-date. One method at the alsa wiki said to put part of the information in the modprobe directory in a conf file and set up certain aliases. Earlier suggestions for putting information in modprobe.conf or conf.modprobe appear to be outdated and a directory with separate files for each device and a conf extension to the files is currently used. The second method from a thread on the Debian forum said to use alsactl init, set sound levels the way you want and then use alsactl save and restore functionality. Older methods using alsaconf instead of alsactl init appear to be outdated as well. Not sure where to put the call to alsactl restore though. Didn't notice that in the documentation.In case it matters, I'm running Debian Stable and have a built-in sound card on the motherboard with AC97 compatibility. It's a Realtek ALC882.

Is there a preferred or better method for setting up alsa? Is there a good pointer to instructions that are not out-of-date somewhere? Would be very interested to hear how others set sound up on their machines. What do others recommend as best steps to do this?

Server :: BIND9 Conf And Zone Files?

Sep 20, 2010

The thing is, I've created a new local zone here (called "local.lan"), and, aparently, it is working fine, and DHCP3-SERVER is updating DNS info through the controls.But sometimes I get some strange answers from the server, like when I do the "arp" command in one of the clients, and get the server's hostname "mixed" with it's own reverse, like this: "dns.local.lan.2.168. | ether | 00:02:1e:f5:61:74 | C | eth0". Other thing is that sometimes my DNS don't update when a computer "enters" the lan. In the /var/log/syslog the DHCPOFFER appears, but the information about the DNS update isn't there.So, I would like to show you my named.conf file and my local zone db file, and get some feedback from you (what would you change... what is wrong...).

General :: Resolv.conf Search Limited To Six?

May 11, 2009

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.

Server :: Use Resolv.conf To Have A Local DNS Entry?

Jan 10, 2011

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?

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?

Ubuntu Networking :: Resolv.conf Keeps Getting Reset By Something

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.

Fedora Networking :: Resolv.conf Not Replaced

Nov 1, 2010

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.

Networking :: Resolv.conf Gets Rewritten On Reboot Even If Chmod 444?

Dec 1, 2009

my rounter causes puppy to write an improper dns entry in resolv.conf. Consequently I have to manually write it, then I have to place a command on it to make sure it doesn't get rewritten on boot, or after a couple of hours use. I had this problem with xubuntu as well.

[URL]

I solved this problem in ubuntu by using the chattr command.

[URL]

Puppy won't let me do this. When I use the chattr +i /etc/resolv.conf, it gives me this error. chattr: Inappropriate ioctl for device while reading flags on /etc/resolv.conf I tried chmod 444 but it had no effect on reboot. resolv.conf was rewritten again. How can I make sure this file does not get rewritten. Why won't chattr work?

Networking :: DHCP Get IP Address But Not Overwrite Resolv.conf?

Aug 16, 2010

I have an Ubuntu 10.04 server. It gets its IP address by DHCP (the router has a fixed reservation so it always gets the same one). However, it needs its nameserver to be itself, and not the DNS servers given out by the router. How can I make dhcp not overwrite resolve.conf?

(Yes I know I could just set a static IP. But I'm testing stuff out here, and want to know if it can be done without doing that.)

Networking :: Resolv.conf Doesn't Work With Secondary DNS?

Jan 11, 2010

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

Ubuntu Networking :: KVPNC And VPN / Errors The /etc/resolv.conf?

Feb 4, 2010

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.

Ubuntu Networking :: /etc/resolv.conf Not Updated On Startup?

Mar 9, 2010

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

Networking :: Timeout Options In Resolv.conf Have No Effect

Jul 10, 2011

Im running several linux boxes, all redat enterprise linux. Versions vary between 4 and 5.

Since we have problems with our DNS servers, Im trying to lower the DNS resolve timeout to the minimum to avoid system hangs etc.

However, it seems that nothing I do have any effect. when Im running time nslookup whatever.com or time host whatever.com while my first DNS server is down, it always takes about 1.09sec as opposed to 0.09sec when the first server in the list is available. I tried playing with options timeout:X attemps:X but it simply doesnt seem to do anything, even if I set it to high values. Some internet posts suggested having timeout:0.5 or less, but that also doesnt seem to do anything.

when I use:
options timeout:0.3 attempts:1
- doesn't do anything.
options timeout:1 attempts:1
- doesn't do anything.
options timeout:10 attempts:3
- doesn't do anything.

It doesn't work when I put it in the first line of the file. It doesn't work when I put it in the last line of the file.

It doesn't work if I put it in "export RES_OPTIONS=options timeout:X attempts:Y"
I tried it on 2 different machines.
