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 :: 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 :: 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 - 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 :: Always Need To Run Dhclient Manually For Connection

Aug 9, 2015

My network configuration is in a weird situation, that I always need to run dhclient manually each time after a network connection is established. When my computer connects to a router, sometimes it won't get a valid IP, and it uses an automatically generated fake Internet IP. In this situation, it won't connect to the Internet at all. Sometimes it get a valid local network IP, but still cannot connect to WAN, and could only connect to my router's address (both through ping and through router's management webpage). In both situation, it can be solved by a simple dhclient run.

This is my /etc/network/interfaces file:

Code: Select all# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
iface wlan0 inet dhcp

and this is my /etc/NetworkManager/NetworkManager.conf:

Code: Select all[main]
plugins=ifupdown,keyfile
dhcp=dhclient
#no-auto-default=FE:50:52:BE:46:4C,

Debian :: : /etc/resolv.conf Overwritten By Network-manager?

Sep 2, 2011

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

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.

Ubuntu Networking :: How To Keep /etc/resolv.conf Static

Apr 22, 2010

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)?

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

Aug 26, 2011

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.

Maybe its set to be not written by anyone other than networkmanager ??

Networking :: Sysctl.conf Settings For Best Internet Connection Speeds?

Mar 7, 2011

Last week I attempted to get "up to speed" with my Comcast cable connection... Ubuntu 9.10, Dell Vostro 400 desktop, Firefox 3.6.13... Comcast says I should have 12 Mbps connection... if I get 1.0 Mbps, I'm doing good... they just tested everything, and said everything is fine on their end. They use [URL] and connects to a server in Chicago, 60 miles away. That gets fantastic speeds, and it's a durn shame the internet doesn't store all its files there!! I use [URL] for my tests, and it uses a server in Dallas TX.

I go to my girlfriends house, and her AT&T DSL line has d/l speeds of 4.5 Mbps or better!!! She's running XP Pro on a Dell machine. So, started digging on the web and thru the forums, and found this:

[URL]

But, like ALL too many things, it's dated... it's from 2008... I've set my settings to what is there, and disabled ipv6 in Firefox. Hey, now, I'm sometimes up to 1.4 Mbps!! Also found this, but no date...

[URL]

Reading forums, I see that folks have said there is a network connection problem with 9.10... and then I see that others are saying the same thing about 10.04 and 10.10!! I have 10.10 on my laptop and had to fight to get its Atheos card to be recognized. Running some tests [URL] gives me weird results: Download 2.64 Mbps, Upload 4.12 Mbps. NOT what it should be. Similar results from testmy.net.

Dunno exactly what info is needed... Speedguide.net gives me results below, but I've tried changing numbers (says my RWIN is low) and nothing changes:

--------------------------------
TCP options string = 020405b40402080adf1dca100000000001030306
MTU = 1500
MTU is fully optimized for broadband.

[code]....

So, today, find, once again, that I'm d'ling in the range of 90/KB/s (719 Kbps)... disgustingly slow. I go on my HP laptop and run the test, and it says 1.6 Mbps. So, desktop directly connected to router is not even 1 Mbps, and wireless connection is faster? Neither of which is close to what I should be getting...

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

Ubuntu Networking :: Resolv.conf Doesn't Work?

Oct 12, 2010

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.

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

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 :: 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.

Fedora Networking :: Name Resolution: Resolv.conf - NetworkManager - Nameserver

Mar 22, 2009

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?
