http_access allow our_networks we have divided according to floors ,like 1st floor ip range is 10.1.60.0 2nd floor 10.1.70.0 ,third 10.1.80.0 and so on. All IP ping each others successfully.
I need to create two Access Control Lists for my networks using SQUID proxy. The ip address range from 165.165.42.10 to 165.165.42.50 for one network and from 165.165.42.60 to 165.165.42.90 for another network. How can I make it?
I am using Squid server on my Red Hat Linux machine.Squid is functional and clients are access through proxy.I want to ask that if I want to open my squid.conf file for any changes should i first stop squid and then do the changes .
I have encountered a problem using squid, I am currently configuring my squid to deny all http and https except 1 external dst ip address which I will use to connect trough RDP, how can I configure my squid with what I want to accomplish?
i have squid 2.6 installed on centos i created acl which should apply to this ip range i.e 192.168.1.10-192.168.1.15 and excluded 192.168.1.13 how can i do
i have just install Sarg-2.2.3.1.tar.gz but When finished compiled i cannot see sarg.conf (in directory /etc/.. or /etc/httpd/conf.d). May i know where is it.?? I'm not sure compiler which it's work good or not good. Some logs show in here:
Is there any way to associate a group to subnet in dhcpd.conf? I want hosts in a specific group to be locked to an IP range defined in subnet. Something like this:
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:
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?
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.
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)

We have a DSL , how can we calculate the available bandwidth so that we can shape the packet, We can assume the bandwidth to be 100mbps on the ethernet interface However, in DSL devices, the train rate(Bandwidth rate ) is varies according to different situation. How can i get the available bandwidth rate(from varies)?. Any method is there for getting the available bandwidth value..
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?
Currently I have the following configuration on pptpd.conf which allows 250 connections :localip 192.168.10.1remoteip 192.168.10.2-254connections 250I would like to increase the connections to 500 , so I need more remoteip , what is the correct format for defining more remoteip
I want to connect to my office intranet without utilizing internet, there is aprox 210 ft distance and i cannot locate my N router's signal even when i installed the router outside of the building, the server is redhat enterprise, and want to share filehosting and internet with the office to cut down costs.
Office building with intranet>--------<210ft>----------my apartment
I am willing to invest some money in this setup but undecided how to extend the network, someone told me i can use a router in repeater mode but i cannot find any such router, my employer has allowed me to use the office network (so nice of him) but at my own setup.
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...
I use F12 and I need help with correct syntax to specify range of IP address in hosts.allow or hosts.deny or in /etc/exports file eg. 192.168.1.100 to 192.168.1.255.
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.
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.
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.
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.
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?
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.
I have a Gateway ML6721 laptop that uses a Realtek RTL8187B for wireless comms. I am very new to Ubuntu and Linux. I am trying out linux using a usb stick, 16Gb with a 4Gb persistence. If I stay in the same room as the router there is no problem. If I walk too far, I get disconnected. Works fine in windows throughout the whole house. Is there a setting I can change or do I need to use a different driver?
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?
I am using squid to controlling access to the internet all is working fine expect one of the user who is using outside organization portal to connect internet. But whenever he tries to enter in the portal by typing (EXAMPLE)url. Permission denied error from squid occur.
How can i allow this portal in squid. So squid will allow this to access.
I can connect to the internet and browse. I'm wired and using DHCP on a Windows network. Updating Ubuntu or downloading programs takes hours for 52MB of updates. Why? I read some articles that mention Network Manager needs to be enabled at the .conf file. Can I edit this using GUI or command line only?
My squid server works fine in fedora 11 system . Is there any web like interface for admins to create,change,modify users of squid and to view their logs.
