Ubuntu :: Search For A Wireless Network In Range Like Windows

Apr 28, 2011

I downloaded Ubuntu 10.04 yesterday and installed using Wubi. I have downloaded ndiswrapper and ndisgtk and installed the drivers for my wireless adapter. My last question is how to make Ubuntu actually search for a wireless network in range like Windows does. So far, I like Ubuntu but want to connect to the 'net.

General :: Search Within A Log File Within A Time Range

Jun 24, 2011

I want to search in my apache log, for events which have occurred say between 11:00 AM to 2:00 PM. I have got few scripts/commands but they are not conclusive, some of then are trying to do an exact match(awk) and for some i am just getting the pattern wrong (eGrep)

I am running RHEL.

Apache log eg:
================================================================
10.92.120.129 - - [24/Jun/2011:01:29:07 -0500] "GET /favicon.ico HTTP/1.1" 302
================================================================

now if i want to find out the logs from 1 PM to 2 PM

some example i had was:

cat <apache.log> | grep -E '07/Apr/20110[1-2]:[0-5][0-9]|02:00)'

small script in which i can pass the start time and end time range, and it should give an output of the rows which fall under that time range.

Programming :: Perl - Stop Range Search At End Of An Array?

Dec 7, 2010

I have data that looks similar to this -

Quote:

John Smith (Address)
123 Main St
Unit 1

[code].....

So I need everything between each name, but I am not guaranteed that each time I match a name that I will have the same amount of lines, so I do a range pattern search line this to get all lines, no matter if there is 5 or 10 or 15. I simply do a loop that goes through the whole array until I hit the match, and this is my search pattern.

Code:

if ($LINE =~ /^s+$SELECTED_NAME/ ... $LINE =~ /(Address)/) {
push @ADDRESS_INFO, $LINE;
}

This works perfectly... until I hit the end and it doesn't get its final pattern match because it's at the end and there is no next entry with a (Address) line. So as a 'hack', I ended up inserting a final scalar at the end of the array that just says (Address) so it knows it's at the end. Ideally though, I'd like to do an "or" statement that says search for Address || return true if I hit the end of the array. How would I match on "End Of Array" essentially?

Ubuntu Networking :: Get Wireless Network Adapter To Be Read By 'Windows Wireless Drivers'

Nov 24, 2010

I recently reformatted and dual partitioned to both Windows 7 as well as ubuntu 10.10. Loading works fine and Windows 7 is 100% operational. I cannot seem to get my wireless network adapter to be read by Ubuntus 'Windows Wireless Drivers' gui. Here are the steps that I have done THUS far, to make sure that we are all on the right path. Before I go any further, my wireless network adapter is an old school WUSB11 Linksys Wireless Network Adapter (running version 2.6).

1) Downloaded and installed "ndiswrapper" from ubuntu's main website. I downloaded the common, utils and ndisgtk files and installed them accordingly.
2) I extracted these three files to the desktop of Ubuntu and accessed the terminal page.
3) From terminal I typed "cd Desktop" to change the directory to the desktop.
4) Next, I typed in "Sudo dpkg -i ndiswrapper-common_1.54-2ubuntu1_all.deb
Sudo dpkg -i ndiswrapper-utils-1.9_1.54-2ubuntu1_i386.deb
Sudo dpkg -i ndisgtk_0.8.5-1_i386.deb"
5) This installed Windows Wireless Drivers gui successfully and I can access it.
6) I have downloaded the driver files for the adapter from the cisco website and searched them for the required files needed.
7) After extracting the .INF file from the "Drivers" directory named "NETUSB.SYS" (I wasn't sure if the other associated files within the same folder needed to be present together with NETUSB so I moved everything to the desktop) I typed in "sudo ndiswrapper -i NETUSB.inf". After accessing the Windows Wireless Drivers gui I have noticed that the 'netusb' driver is present yet under it, the system states "Hardware present: No". This leads me to believe that maybe I installed incorrectly or my "fireware?" is not present? I was reading through the installation guide posted on the ubuntu website that in addition to the .INF file we also need the BIN file(s)? and SYS file(s)?.. The folder with the drivers for my adapter contains a BIN file but it is not within the "Drivers" section of the folder.
9) Upon mousing over the network Icon naturally my hardware is still not present.
10) From what I gather after the system finds the hardware I am to write into the terminal

Ubuntu :: Windows XP Only Wireless Network?

Feb 11, 2010

I attend a community college that has 5 campuses. All campuses have wireless networks. For two weeks I have been trying to connect to their network with my netbook (Ubuntu 8.04) with no luck. I call the IT department today and they tell me that their network ONLY supports Windows XP. Windows 7, Vista, and all Linux OSes are unable to connect. The network shows up but will not connect. They do not know what the problem is or how to fix it.

Ubuntu Installation :: After 11.04 Install - Wireless Range Worse

May 2, 2011

My only unhappiness with 11.04, after I installed in on 4/28 on my Eee PC 1000H (dual booting with Windows XP), is that the range of wireless reception in my house, from exactly the same spot as before, has worsened considerably. No problem when running Windows (which I'd rather not do, of course). Could the upgrade have installed a new driver for the wireless hardware that isn't as good as the previous one?

OpenSUSE Wireless :: Range Of Less Than 3 Feet?

Dec 31, 2009

I thought I would drop a few findings relating to a strange problem I don't have the answer to.

I have installed both Ubuntu and now OpenSuse (alongside Windows XP) on a thinkpad T40. I own a linksys WRT54G2 wireless router.

Windows XP runs fine, and connection to the wireless network is fine everywhere in the house.

however the first time on Ubuntu and now on Opensuse 11.2, the laptop needs to be within 3 feet of the router in order to connect to the wireless network!

Strange thing is that the laptop can see the network from anywhere in the house (with a signal strength carying between 60 and 90%) - however impossible to connect.

Suse is running the ath5k driver for the internal network card.

OpenSUSE Network :: IP Range In Firewall?

Mar 29, 2010

I am trying to add a custom allow rule in the firewall for a range of IPs from 74.201.102.0 - 74.201.103.255, what exactly am I supposed to enter in the source box? I believe I have to add two separate rules for 102 and 103, and I put /24 at the end of both, is this correct to get the whole range of IPs?

General :: 12 And Windows 7 - Get Wireless Connection To Work On The Network?

Apr 3, 2010

how to get my wireless connection to work on the network. I don't see anywhere to go to see if the wireless adapter is even setup in Fedora. My other question is when I boot up and get the options to select the OS the first one is Fedora but the other one says it is other.

I think that is is booting up the recovery partion of Windows. I don't know how to change it so that it is looking at the correct portition. I know it has something to do with the menu.lst file but when I try to open it says that I do not have premission. I am not sure where to go to edit it.

Problem is the very low quality of wifi (works only in 2meter range)

I have ra3090 hardware.

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

Jun 22, 2011

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.

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)

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?

Ubuntu Networking :: Wirelessly Connecting Desktop With A Linksys Wireless Range Expander?

Sep 30, 2010

After spending several months coming up with ideas (and ultimately failing), I have found the easiest and simplest way to connect your Ubuntu desktop (or laptop w/o a wireless adapter/card) to the Internet using only a Linksys Wireless Range Expander and an Ethernet cord.

YOU WILL NEED:
Linksys Wireless Range Expander (WRE54G)
Ethernet cable

Linksys wireless router (that is providing your home/office with wireless Internet) The WRE54G can be purchased online through various websites, including eBay. They run anywhere between $10 and $40, but it's going to be cheaper than a USB Wireless Adapter (and no software needs to be installed, making it universal for most Linux distros).

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 Installation :: In Windows 7 (64 Bits) File System Installer - Cannot Detect Wireless Network

Nov 28, 2010

Ubuntu in Windows 7 (64 bits) File system installed using Wubi I got Ubuntu 10.04 LTS intalled using Wubi. That means Ubuntu resides inside Windows file / folder system. It also means Ubuntu does not have its own partition. Here is what I found out:

1) It cannot detect wireless network unlike Win 7 on this same laptop. However, when I plug in ethernet cable, it was able to detect it. Is there a fix this problem?

2) I cannot see Windows folders. How do access windows folder from Ubuntu side and vice versa?

3) I forgot to set the disk space for Ubuntu during install and I think the default is 17 GB.Would this cause me problems? If so, what do I need to do? How do I expand the disk space for Ubuntu?

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 }'

General :: Windows - Routing Everything Except A Certain IP Range Through An OpenVPN Tunnel?

Aug 31, 2011

I've been working with my OpenVPN server for a while, and I have a rather interesting problem. I need to redirect all client traffic through the tunnel except for a couple IP's that need to be resolvable locally. The way I'm doing this is pushing these routes from the server:

Server 'PUSH' directives

push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"

I'm seeing that translating into these Windows routes:

Windows routes occurring

Wed Aug 31 15:14:35 2011 PUSH: Received control message: 'PUSH_REPLY,redirect-gateway def1 bypass-dhcp,dhcp-option DNS 8.8.8.8,dhcp-option DNS 8.8.4.4,route 10.8.0.1,topology net30,ping 5,ping-restart 30,ifconfig 10.8.0.6 10.8.0.5'
Wed Aug 31 15:14:35 2011 ROUTE default_gateway=192.168.1.254

Wed Aug 31 15:14:40 2011 C:WINDOWSsystem32
oute.exe ADD 199.[*.*.*] MASK 255.255.255.255 192.168.1.254
Wed Aug 31 15:14:40 2011 C:WINDOWSsystem32
oute.exe ADD 0.0.0.0 MASK 128.0.0.0 10.8.0.5
Wed Aug 31 15:14:40 2011 C:WINDOWSsystem32
oute.exe ADD 128.0.0.0 MASK 128.0.0.0 10.8.0.5
Wed Aug 31 15:14:40 2011 C:WINDOWSsystem32
oute.exe ADD 10.8.0.1 MASK 255.255.255.255 10.8.0.5

I've hidden my server's IP beginning with 199 for security purposes.What I've gathered.I'm assuming that 0.0.0.0 is a kind of code for "everything," so I'm not sure how I could get this to work, but the general idea is that I need a specific IP range (172.16.*) to be resolvable on the LOCAL NETWORK (of the client) meaning it does not go through the VPN tunnel and the client can connect to 172.16.* locally.Is this possible? Routes can be executed through the command line, server "push" or client config options. Any way to get this to work while still routing other traffic through would do, really.

Additional Info: I have the server running on Debian 64-bit and the client running on Windows 7 (although Vista needs to work as well).Client/server configs can be provided if needed.
