I am a noob in Ubuntu and I would like to create and script or file which when clicked sets my WiFi interface's power lower, down to 7dBm. I already know how to do it by typing on the terminal, I just write:
#sudo -s
#my password
#iwconfig wlan0 txpower 7dBm

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

After upgrading from 10.10 to 11.04 via the online upgrading method I had much trouble getting wireless to work but after following the instructions at .Driver/bcm43xx it burst into life, that is until I powered off and now I have to sudo modprobe b43 before the hardware button for the wifi will work and and then I am able to get online. This is for every power on session!! Once enabled it will switch on and off via the hardware button and the light is operational. Before the sudo modprobe b43 the buttonoes something as evidenced by sudo rfkill list after each press of the button. Is there any way to have the command sudo modprobe b43 inserted somewhere in the power on sequence? This was a working function on 10.10!

View 2 Replies View RelatedI'm trying to create EoIP interface on ubuntu so i can create a simple tunnel to my mikrotik router. Is there anyone know how or even done that? If EoIP is not possible, is there any other simple way?
I had already read and thought about doing it with OpenVPN, but when I read the community documentation for OpenVPN on ubuntu 10.10, I fear it won't connect the tunnel to mikrotik OpenVPN server, since OpenVPN on ubuntu uses 2 certificate and 2 key files(as i read on the docs), but mikrotik configuration, i can see only 1 certificate can be applied on. This confuses me and make me decide to use EoIP(but i can't find any tutorial/docs about it). I don't actually need the encryption and security, i just need to create a tunnel for ubuntu and mikrotik.
Basically I am looking for a simple way to create a universal nickname/alias for a interface.We ship servers that have upto 6 NICs on them. The user can have those NIC configured as either ethN, bondN or vlanN interfaces. As we need to provide NIC status information we would like to be able to run commands such as
Code:
ifconfig INTERFACE1
that would map to whatever the user had already configured.
I see there is a driver module for network card in my system. I have 2 identical network cards in my system the 1st one works well, but the second one.. My system refuses to create interface on it.... lspci

I just removed ubuntu-desktop in favor of kubuntu-desktop. Now I can't create an ad-hoc wifi connection however hard I tried from network-manager. It simply is not visible to other PCs.

I had originally planned on buying a USB 2.0 audio interface to use with my first home recording studio, but it sounds like Linux support is pretty horrible for these devices. On the other hand, the FFADO project seems to be very promising, so now I'm looking at getting a firewire interface. The only problem is that all I have on my laptop (sony vaio VGN-N365E) is a little 4-pin firewire port. If I'm not mistaken, those don't provide any power. Will this work with any interfaces (maybe one that has it's own external power adapter)? Or is there an adapter I can get to convert it to a full firewire port and add power?

I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.
I am having some serious speed/connection issues with my laptop's WiFi card, and it has been suggested to me to disable power management for it, just as an experiment. However, when I run "sudo iwconfig wlan2 power off," I receive the error:
"Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan2 ; Operation not permitted."
I installed 10.04 1st by making a partition with bootcamp on MacOSX.Then I formatted the partition according to Ubuntu's instructions. I didn't install rEFIt, because I prefer to just hit the alt (option) key.I made the necessary adjustments according to URL...Community Ubuntu Documentation - and everything seemed to be working fine.I upgraded to Maverick and everything seemed to be working fine aswell.But then I noticed, that the wireless signal keeps failing and I'm asked to put the password again and again..
I don't think this is due to the upgrade from 10.04 to 10.10, but I just noticed it recently, maybe because of the air humidity, the signal was stronger a few days a go.. don't know!!Is there anything I can do?Perhaps install a new driver, or another wificlient, like Wifi-Radar??
On ubuntu 10.4, I upgraded my laptop from a fluky Broadcom 4322 wireless card to a yummy Intel 5300. The system recognized the card as far as lspci and lshw were concerned, but it was disabled. I used "sudo ifconfig wlan0 up" to get it active, removed wicd and installed nmanager, and I could access the internet via web browser and mail.
The issue is that other programs (kismet, wireshark, zenmap, anything that I use at my job) do not recognize the new wlan0 interface at all. I've uninstalled completely from synaptic then reinstalled things like wireshark, but under interfaces I get nothing, not even eth0. Nothing looks askew in syslog or the relevant lshw/lspci searches. Does anyone have an idea on this? The Intel 5300 is rolling along without a hiccup so I doubt the issue is there
I dual-boot Jessie with Windows 10, and I recently guessed that the 'fast boot' (hibernate on shutdown) feature of Windows doesn't properly shut down the RTL8188EU NIC plugged into my PC. So when I boot into Debian, it isn't properly recognised by the driver and I have to completely shut down the PC to make it work.
Is there a way to automatically cut the power to the wireless NIC on startup and then reenable it so I don't have to do this?

View 3 Replies View RelatedI run a linux box as a gateway behind a satellite modem.

The satellite operator is saying this is normal, but I have my doubts.
Has ICMP got a lower priority? Should I really be seeing this behaviour? I understand that if it was a TCP packet then it would just be queued until the previous acknowledgement has been received. And if it was a UDP packet then it would have been dropped, but how does ICMP deal with these situations during heavy traffic?
