Mar 3, 2011

I am going to configure squid in my linux box.I have different kinds of ranges in my office.The default is as under

Code:

acl our_networks src 192.168.1.0/24 192.168.2.0/24
http_access allow our_networks

can I add my own ranges as

Code:

Software :: Gnuplot - Combining A Linear Range And Log-scale Range In The Same X-axis?

Apr 24, 2011

I want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:

Code:

X Y
0 100
10000 80
20000 75

[code]....

Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:

Code:
|-----|-----|-----|-----|-----|-----|-----|-----|-----|
0 20k 40k 60k 80k 100k 1M 10M 100M 1G

(The abbreviations k-M-G are not the important point. Just shown for clarity)

Programming :: Bash Script To Ping A Range Or Own IP-range?

Apr 11, 2011

I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!

The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???

echo "Enter beginning IP-adres:"
read begin
echo "Enter ending IP-adres:"
read end
ping -c 1 $begin [..] $end

The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?

#!/bin/bash
ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |
cut -d: -f2 | awk '{ print $1 }'

Networking :: How To Express Range Of Ip Addresses

Sep 22, 2010

I do not currently fully understand relationship between binary numbers and ip addresses and subnet addresses; nor am I asking for an explanation here at LQ, when there are plenty at wikipedia and other places...

Even after reading the wikipedia article on it, I still don't grasp it completely, so I was hoping that someone who grasps it in its entirety could answer a simple question.

How can I express the range of ip addresses from 172.22.22.200 - 172.22.22.230 ?

I was trying to make a rule for iptables that only did nat on that specific range of ips, and when i tried used the "-s" flag followed by 172.22.22.200/11 it always changes to 172.0.0.0/11 in the actual rule that is created and displayed by iptables -t nat -L.

I already have many hosts defined on my network, and rather than going through each one and changing its ipaddress to 172.0.0.#, I was hoping to learn a way to represent them in the iptables rule.

Networking :: Using NMAP On A Range Of IP Addresses

Hopefully Ody has found a result in the 5 years since he posted this question, for anyone else looking for an answer
NMAP scan for a range of individual IP's can be done using the '-' for example:
(this is accurate as of 2010, actual results have been altered to match OP's address range)


$nmap -sP 192.168.0.1-14

Networking :: Determine How Many Subnets Are In A Network Range

Jan 12, 2010

I am trying to remember how to determine the number of subnets there are in a given subnet range. The example range is shown below:Quote:217.133.64.0-217.133.127.255nce I did the binary conversions of the two addresses shown, the address that I got when comparing the two was the following:Quote:217.133.192.0he number of subnets I got from his was 63.Correct me if I am wrong, but is the number of subnets the difference between the number, in this case, the third octet and 255? If there is another, or correct, way of determining the number subnets what would it entail?

Fedora Networking :: Turn A Laptop Into A Range Extender?

Oct 7, 2009

Is there a way to turn a laptop, or any PC with a wifi network card, into a wifi range extender? Suppose I have the usual wifi router, but unfortunately the signal doesn't cover the whole house; a solution is a range extender, but I thought: if I have a laptop, placed in the same room where I would put that range extender, can't I use THAT as a range extender too? After all, range extender at the very heart are "stripped-down" routers, which in turn are stripped down PCs equipped with a stripped-down version of the Linux Kernel...

Ubuntu Networking :: Extending The Existing Wifi Range?

Nov 6, 2010

I have an ADSL router, wireless, at my home. However, the wifi range is extremely limited. I want to be able to have the wifi all over the house, or atleast about 20 feet away from till where it reaches till now (father and grandfather under the same roof can be a problem.)

So how do i get to it? can I get another router and have it connect to the present router? The present one is one with ethernet and wifi outputs, limited to 4 connections i think, and i have it configured to dial to the net automatically, i.e.: no dsl dial up from pc reqd.

Ubuntu Networking :: Network Manager Tries To Connect To Out-of-range Networks

Jul 2, 2010

I have a problem with network manager. I use Ubuntu 10.04 on a Dell Latitude D530. I used to have the same problem with Ubuntu 9.10 before I upgraded. I typically connect to two wireless networks: HOME and WORK. Both networks are set to automatic connection mode. I am at work, I connect to the network WORK. At the end of the day, I just close the lid and go home. At home, I open the lid and have the following problem: network manager still displays the network WORK whereas it is clearly out-of-range and it automatically tries to connect to it. It does so until network manager asks if the password is correct.

If I want to connect to HOME, I have to tell network manager to do so. Then, I receive a notification that I am disconnected to WORK. Next morning, I go to work, and I have the same problem, network manager tries to automatically connect to HOME. What I would expect from network manager: when I am at home, NM automatically connects to HOME and does not display WORK, when I am at work, NM automatically connects to WORK and does not display HOME.

Ubuntu Networking :: Get A Short Range To Connect Laptop To The Wifi?

May 3, 2011

With most Linux distributions, I can only get a short range to connect my laptop to the wifi. However, when using Ubuntu 10.10, this issue seemed to cure itself and I was able to use wifi in my room. I recently installed Ubuntu 11.04, but suddenly my wifi issues have come back again - I can only connect if I am near my router.

I am using an Intel Wifi 5100. I should also note I can get a wifi connection if I boot into Windows 7.

Ubuntu Networking :: Alpha 2W Disconnects - Can't Connect To Any Network In Range

Working on ubuntu 10.04 on an IBM Thinkpad X61 laptop with an Alpha 2W wireless usb card on wlan0. Once in a while the wireless network disconnects and can't connect to any network in range (open, wep, wpa, wpa2). It looks like it's trying to connect but then asks for a password (even if allready given one) and if open just not finishing connecting and trying to connect to another network. Happends the same with wicd. Network card is working ok. Also with other computers. Drivers are installed correctly and power consumption management is off.

Networking :: DHCP3 Server - Setting Double Range Of IP Address

Apr 27, 2010

I would like to set a double range of IP address with my DHCP3-server. Now, I have eth0 (which is my only network card) with this IP address : 172.16.93.1 and I have created a second interface eth0:1 with this address: 192.168.3.1. The goal is to give an IP address 172.16.93.X to phones (with option 66) and the IP address 192.168.3.X to the computers.

This is my DHCPD.conf :
ddns-update-style none;
option domain-name "mycompany.com";
option domain-name-servers 172.16.93.1;
default-lease-time 3600;
max-lease-time 2347200;
authoritative;
log-facility local7;
option ip-forwarding off;
default-lease-time 20;
max-lease-time 20; .....

Right now my DHCP server work fine, (I means, no error at the startup ) but the server give always the same kind of IP address, whatever if it's a phone or a computer. I notice something "wired", if I put the :
subnet 192.168.3.0 netmask 255.255.255.0 {
range 192.168.3.100 192.168.3.199;
option routers 192.168.3.254; }
(Which is first in the dhcpd.conf) after the "subnet 172.16.93.0 netmask 255.255.255.0", the server will give IP address 172.16.93.X at all the clients. Is it possible to give more than one IP range with one network card at the same time? And how set the option 66 to only give IP address (172.16.93.X) to the phones?

Ubuntu Networking :: Create A New Virtual Network Using A Subnet Of Public Range

Jan 27, 2010

There seems to be a lot written about virtual networking but I am not sure what approach to take in my situation. My local subnet has a public block of 128 addresses. I have a virtual host running on my machine. My machine has a static address and I'd need to assign one to the guest. I have edited the guest's interface file and assigned a public address to it's eth0. However the guest cannot ping out and I can't ping in.

By default the virtual machine manager creates a virtual network (virbr0) and assigned a private address range to it. I have tried to create a new virtual network using a subnet of my public range (/31) but the manager says the range must to a minimum of 16 addresses (/4). It doesn't look possible to achieve my aims using the virtual machine manager.

In the past I have used the procedure laid out here:[URL].. which is to manually create a bridge. I am not sure that is relevant for my 9.10. I think I would have to disable the network manager if I were to do that and I am not sure how to do that.

Ubuntu Networking :: Firewall - Block Incoming / Outgoing Connections To IP Range

Jul 4, 2010

I am still new to ubuntu and I use firestarter as my firewall tool and I was told that its just ufw in a gui. Well anyways I noticed a connection to 174.129.241.144 using https and python, I didn't have any scripts running and my browser was closed, I read the man files for ufw and it said to do something like deny from 174.129.0.0/12 and I want to block all incoming and outgoing connections to this IP range and I was wondering how to do that, I heard of iptables that it would be able to do this but I dont know anything about it. What I should learn so I can handle these kinds of situation in the future and how I can block this ip subnet or also what does the /8, /12, and /16 stand for?
