Aug 19, 2010A server at which I have an account has changed things. The new /etc/resolv.conf fails to resolve a lot of addresses. I can use dig @ with OpenDNS and resolve them successfully, but how do I get apps, such as sendmail, to use a nameserver I specify? It'd be nice if a user could have his own additions to resolv.conf, but I don't see that in the docs, or a way to get sendmail to use a specified nameserver.

Mar 27, 2010Ok, one more question on nameserver security. So I was reading this post and it recommended not setting a defined outgoing port for your nameserver due to the Kaminsky vulnerability.What is the proper way to lock down a nameserver, but avoid the vulnerability of only allowing incoming and outgoing requests on port 53

Ubuntu Networking :: Nameserver Not Working

Ubuntu :: ISP Change Blocks Nameserver Access?
Jan 29, 2011I just switched ISPs from a local vendor to Wild Blue. All my Windows boxes adopted automatically. My Ubuntu 10.10 workstation can find no sites, period. My old resolv.conf said:
# Generated by NetworkManager
domain sdc.org (<- my old local ISP)
search sdc.org (<- my old local ISP)
nameserver 192.168.0.1 (<- correct IP V4 address for my router's front end)
This has not changed, and I guess my IP stack is searching for sdc.org domain addresses on WildBlue.net, which don't exist there. After many hours trying to speak with WildBlue Tech Support people, I've decided that domain search questions are beyond their ability to comprehend or discuss. If I could ascertain the domain(s) to search I'd just edit the silly file.
Has anyone else connected with Ubuntu 10.10 on WildBlue?

Debian Configuration :: Picking Up The ISP's DNS Servers And Using That As The Nameserver Entries?
Aug 15, 2010How can I have /etc/resolv.conf point to my router address as the nameserver nameserver 192.168.1.1
instead of picking up the ISP's DNS servers and using that as the nameserver entries? Reason being I have more than one ISP account, and when I change I do not want to have to remember to restart the networking service. because i often forget.
Ubuntu Servers :: Have To Enter NameServer Manually After Reboot

Server :: SOA For Nameserver Can't Be Retrieved, Possible Port Or BIND Misconfiguration?
Aug 24, 2010My configuration: CentOS in a VPS environment, I have 2 static IPs at my disposal.I'm having trouble setting up my nameservers. I've registered the nameservers with my registrar and supplied the GLUE records, however my registrar has not yet applied this information into the DNS zone, because my nameservers fail to generate a response on port 53.DNS check says the following about my nameserver address:Checking SOA records for domain. Domain server is not answering to UDP requests on port 53. Possible problems: A firewall is blocking port 53, server is down, server is not running software for handling dns requests.So the only two possibilities I see is that my port 53 is somehow blocked or not properly set to accept and send the correct traffic or that I've misconfigured BIND.
View 2 Replies View RelatedFedora Networking :: Name Resolution: Resolv.conf - NetworkManager - Nameserver
Mar 22, 2009I 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?

Ubuntu Servers :: OpenSSH Reverse Lookup Using /etc/hosts Before Nameserver?
Apr 6, 2010Like many others I'm running into some reverse lookup issues with SSH. Setup is as follows:
localnet setup
myserver - 192.168.0.x
myworkstation - 192.168.0.y
[Code].....
nslookup tests show that my reverse lookup is functioning correctly. However, if I use "myworkstation" to connect to myserver.mydomain.com using an external nameserver SSH says: "Address 84.162.xx.yy maps to myserver.mydomain.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!"
On myserver the /etc/hosts has the internal address for the server which seems the normal way to go to me. Changing this to the servers external address solves the issue.
Apparently a connection originating from myworkstation arrives from/with my external address, and when its reverse is checked by the server it apparently finds its own internal address for that name in /etc/hosts before doing a nameserver query and thus concludes that internaladdress <> externaladdress which gives the error.
Is there any way to have the server check external DNS before /etc/hosts? Another solution would probably be running an internal DNS, so myworkstation doesn't connect through the 'outside'.

Fedora :: Caching Yum Downloads Across A LAN?
Aug 8, 2011I am currently working on a project at work to do caching across a windows network (web traffic thorugh squid and windows updates with WSUS). It is proving to be an interesting learning project.This got me thinking about my home network. Currently I am running 8 Fedora Computers (with the very real possiblity of more in the forseeable future).
Oviously running "yum update" on every computer and having them download these updates directly on each computer eats a lot of bandwidth on the external link. I would like to know if there is a way to set up a proxy server (or something else for that matter) to cache yum downloads. This way when I deploy a new machine, or run updates, I can save time and bandwidth by only downloading the packages too my LAN once, instead of nearly a dozen times.
General :: Prevent Find - Du - Ls -R From Caching?
Jul 11, 2010I'm currently copying a large number of files over a network. To monitor progress, I tried running watch du. However, the output never changed (or not much, not sure). find . -type f | wc -l always gives me the same number of files as does ls -R. It seems, these programs use caching, which is, in general, a good thing. Does anyone know, though, how cache usage could be controlled? I'm on an Archlinux system and I'm working on an ext4 fs on an encrypted hd.
