Hi gurus,
I am trying to connect to wifi access point with terminal, I set up my own access point (no encryption or MAC filters)
I ran followings commands
Code:
$ sudo iwlist eth1 scanning
eth1 Scan completed :
Cell 01 - Address: 00:11:2F:A2:99:1C

Code:
$ sudo iwconfig eth1 mode managed essid esus channel 6
Code:
$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

But when I use graphic tool in ubuntu 9.10 and then check it with iwconfig everything is OK
Code:
$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

my box and wifi card:
Code:
$ lspci | grep -i wireless
06:05.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
Code:
$ uname -a
Linux cepi-laptop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux
Code:
dpkg -l | grep wireless-tools
ii wireless-tools 29-2ubuntu6 Tools for manipulating Linux Wireless Extens
Also I have another question, lets say I am connected to an AP but DHCP is disabled, also there is running web interface on AP throught I can set up DHCP and obtain IP address. How do I know what is IP of the AP which I am connected, is there a solution or I have to reset AP ?
I had idea to scann whole network with
Code:
$ echo -ne {0..255}.{0..255}.{0..255}.{0..255}"\n" > addresses
$ sudo nmap -sS -iL addresses
I know this is terrible waste of system resources, and my box stops responding and start swaping after I issued echo command
, but I dont know anything else, problably set some kind of broadcast ping or something like that, is this possible ?
What I am doing wrong ? Thanks a lot.
