Networking :: Create A Script To Display DNS And IP Address Information?

Jan 5, 2011

I have been playing with Linux consistently for a couple of months now. I've been a Windows sys. admin for most of my career, so Linux is pretty strange for me. I started off with computers way back with the TRS-80 and then eventually moved to DOS systems. So the command line interface (CLI) of Linux was not completely alien to me, yet my lack of knowledge on the syntax and commands is holding me back. I have come a long way.

Recently I needed to play around with some DNS settings and one of the commands I used frequently in Windows, IPCONFIG /ALL, doesn't have a direct relative that displayed the same information. If you run ifconfig, it doesn't return the DNS servers you are currently using. You have to run a separate command to retrieve that information.

What I have done is created a super simple script that displays the network information for my primary LAN adapter, which is ETH0 in my case. After that, it shows the domain and name server information. Then it pauses for 20 seconds before closing the terminal window.

Here are the contents of the script file:

ifconfig -a eth0
cat /etc/resolv.conf
sleep 20

I simply right-clicked the Linux desktop, choose Create Document, Empty File. I named it something like Network Info. Then I opened it and put this information in it, saved it, and closed it. I renamed the file and added a .sh extension to the end which makes it into a script file. Next, right-click the script and go to properties. In the Permissions tab, check the box next to Execute: Allow executing file as a program. Then click close.

To run the script, just double-click the icon and then click Run In Terminal at the prompt. The terminal window opens, displays the information, and exits after 20 seconds. If you need it longer than that or need a different interface (such as wlan0 for your wireless), you can change or even add that in.

This was all done in Ubuntu 10.10. I know it is very simple and very straight forward and welcome thoughts and feedback about simpler ways to do this. For me, the old-school Windows admin, it's a baby step in the right direction. I am really enjoying learning the Linux OS.

Fedora Networking :: 10 DNS Information Gets Lost After Changing IP Address To Static

Feb 21, 2009

I am using Fedora 10 and when I first installed my machine, I had a DHCP assigned address to my network card. Later on I decided that I wanted to give my machine more of a server role, so I switched to static IP using the system-config-network utility. What happened after that was that I did change the IP address and routing information, but DNS information gets lost at every reboot, so I need to type it back again.

Ubuntu Networking :: Check The Network Connection Applet, It Display Active Information Of Eth0?

Jun 7, 2010

I have a question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.

Ubuntu :: Display Info On CPU Temp & Other Sensor Information?

Dec 17, 2010

Is there a Linux application which can display motherboard and CPU sensor information and which also satisfies one other, absolutely key, requirement: It should be directly usable, after installation, by a reasonably intelligent computer application user. That is, it does NOT require deep internal knowledge of specific hardware or obscure system software customisation. It does not require hours, days or weeks of reading of documentation which is so crafted as to be the antithesis of end-user guides. It must be capable of being invoked easily.

This eliminates all software that the Ubuntu Software Centre lists when performing a search with the term 'sensors', with the exception of xsensors. All other software listed with this search installs without error but is then totally invisible to me - not even listed under 'installed software'. I am aware a key requirement to be a Linux developer is an advanced commitment to play games of 'I bet I can make my software harder to use than yours', but I'm too old for that now. I don't have a need to prove how technically capable I am.

Xsensors installs and tells me where it can be found, but is inadequate as it lists only 2 CPU core temperature readings. It does not give me any indication of motherboard temperature or fan speeds. That's all I want to do - get a simple snapshot of sensor values without having to resort to entering BIOS setup. It's the sort of information that is so easily available using the ASUS-supplied 'asus-probe' software under Windows. Is it possible, given the key requirement previously mentioned?

General :: Display Password Policy Information For A User - Ubuntu?

Jun 9, 2010

Ubuntu Documentation > Ubuntu 9.04 > Ubuntu Server Guide > Security > User Management states that there is a default minimum password length for Ubuntu:

Say the password is to be modified by the user using passwd. Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)?

This is rather than examining various places that control the policy and interpreting them since the process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

Programming :: Create A ZIP In Perl Without Storing Path Information?

Mar 1, 2010

I have the following code snippet:


my $file = 'test/mybigfile';
my $zip = Archive::Zip->new();
my $zipped = $zip->addFile($file);


it simply takes a file (in this case, "mybigfile") and creates a ZIP file containing that file only. Now, my problem is that when I go to decompress the ZIP file, it creates the relative (or absolute, depending on case) path of the original file. To make an example:


$ pwd
$ ls -R


What I need is *not* to store the path information inside of the ZIP file, so that once I decompress the ZIP file I only get the original one without having paths created.

Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting

Dec 16, 2010

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.

So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.

My files are as follows:

Networking :: Dynamic IP Address With PTR Record Versus Fixed IP Address Without?

May 7, 2010

I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.
