According to the man page, host ought to query "the server or servers listed in /etc/resolv.conf," but it only uses the first entry in that file:
thefourthtower:$cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

HOW TO GET THE IP ADDRESS OF HOST IN LINUX WITH USING OF HOST AND NSLOOKUP COMMAND and after getting the ip address how to assign it in the variable
View 4 Replies View RelatedI have a problem, I set a Debian server with no GUI. I have set http_proxy and I want to add ignored hosts for local address like I did in Ubuntu(System->Preference->Network Proxy->Ignored Hosts).How can I do that in Debian (with no GUI only bash) like I did in Ubuntu with GNOME Desktop?
View 2 Replies View RelatedI have the following command:ssh $USER@$HOST "ls /ops/pkg/ec/`grep "PKRTS" /ops/pkg/ec | awk '{print $1}'`* > /tmp/tmp_file"What the above SHOULD do..is, ssh to the host then execute the command.The command should first execute the grep and awk between the back ticks, and generate a file name, then ls using that filename* and write that data to a temp file.However, it executes the grep and awk before even SSH'ing and the command that goes to the server is simply an "ls /ops/pkg/ec/* > /tmp/tmp_file" since the grep and awk return nothing on the local machine.

And I CAN'T EVEN INSTALL ANY SOFTWARE in any linux boxes to determine the remote OS name and version.Can you please enlighten me on how could I find out the OS version of remote host without installing any software or without login to that server.

View 1 Replies View RelatedWhy does ping see audit.median.hu as 127.0.0.0, and why does host -t a audit.median.hu see it as 193.68.35.149? audit.median.hu is just an example site [hosts ads, etc.]
I just have a caching nameserver on my Fedora PC:
I configured my DNS server addresses in the Network-Manager Applet: 127.0.0.1, 8.8.8.8
Even with Wireshark, I can see it:
So the big question: Why don't the host command or my web browser recognize that I have modified audit.median.hus IP address?

View 6 Replies View RelatedI have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
I'm trying to ssh from my laptop to my desktop (both fedora 14) over a local network. I can ping my desktop and get responses, but if I ssh to it, I receive

I can ssh from the desktop to itself.
I am working behind a http proxy (172.30.x.x:3128). I have configured it in my terminal. All the applications such as wget,lynx firefox etc. are working correctly.However all dns utilities like nslookup, host and even ping too are not working.Following is output of host command:

View 3 Replies View RelatedA 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.

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

View 4 Replies View RelatedI 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?
today i found out that my bind9 on debian 5 suddenly failed and it also consumed 100mb of RAM at most times.
nameserver daemon with smaller memory footprint to replace bind9.
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
[code]....
How 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.
I have a small webserver running ubuntu server 10.4. It runs fine except after every reboot, I get DNS errors. I have to manually edit /etc/resolv.conf to add:
Code:
nameserver 192.168.1.1
The address of my internet gateway on my LAN. Obviously I am ignoring the warning in resolv.conf that this will be overwritten.
I tried installing gnome-desktop, which wiped out /etc/resolv.conf (and ultimately failed to install). A comment was left in resolv.conf saying "do not edit..". Where is the proper place to list nameservers in debian?
