configure wireless essid & enc key in debian squeeze?
in [General Linux]
|
From: John Stumbles on 7 Aug 2010 12:42 I'd like to be able to use wired ethernet if it's available, otherwise wireless, with a static IP. It would be neat to be able to also use wireless with DHCP if I'm in a wifi cafe. I've tried network-manager (with knetworkmanager front end) and wicd and both swear blind that I don't even *have* a wireless interface, despite the face that I have the wireless running, manually configured. It shouldn't be too hard to knock up a script to plug some ready-rolled versions of /etc/network/interfaces into the working files and do ifdown and ifup on the interfaces but I can't find how to set the wireless essid etc in a file anywhere and everything I google just says to use network-manager or wicd :-( What I have is, in /etc/network/interfaces: auto lo interface lo inet loopback allow-hotplug wlan0 iface wlan0 inet static address 192.168.1.51 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 /etc/resolv.conf contains opendns nameservers And then manually I have to do: iwconfig wlan0 essid my_essid enc s:my_string That gets the wireless interface up and running. Can anyone help? thanks -- John Stumbles The astronomer married a star

I presume that 192.168.1.0 is like your home or office network? Is a dhcp server running there? If not, you should install (or have installed) a dhcp server and then configure it to feed your 'static' IP address to the MAC of your wireless NIC. This is what I do with my laptop, which has both wireless and wired networking. Both are setup with dhcp and my home office desktop runs a DHCP server and feeds my laptop a (fixed) static ip on my home office LAN: subnet 192.168.250.0 netmask 255.255.255.0 { # --- default gateway option subnet-mask 255.255.255.0; option domain-name "deepsoft.com"; option domain-name-servers 192.168.250.1; option routers 192.168.250.1; option time-offset -18000; # Eastern Standard Time option broadcast-address 192.168.250.255; option time-servers 192.168.250.1; use-host-decl-names on; range dynamic-bootp 192.168.250.128 192.168.250.250; authoritative; default-lease-time 21600; max-lease-time 2592000; host gollum { hardware ethernet 00:0d:60:cc:82:03; fixed-address 192.168.250.5; default-lease-time 2592000; option host-name "gollum.deepsoft.com"; } } My desktop box runs a cacheing / local nameserver and routes to the internet (via ppp over dialup). Both of my machines run CentOS 5.5, but it should work much the same for Debian. > > /etc/resolv.conf contains opendns nameservers > > And then manually I have to do: > iwconfig wlan0 essid my_essid enc s:my_string > > That gets the wireless interface up and running. > > > > Can anyone help? > > thanks > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

Sorry I didn't mention: I only had the loopback interface lines in /etc/network/interfaces when I tried network manager. > I presume that 192.168.1.0 is like your home or office network?

You might need to add 'dhcp' lines to /etc/network/interfaces in order for network manager to see them. I am not sure how Debian does things. In my case (CentOS), I have ifcfg-eth0 and ifcfg-eth1 on my laptop: gollum.deepsoft.com% cat /etc/sysconfig/network-scripts/ifcfg-eth[01] # Intel Corporation 82540EP Gigabit Ethernet Controller (Mobile) DEVICE=eth0 BOOTPROTO=dhcp HWADDR=00:0D:60:CC:82:03 IPV6INIT=yes IPV6_AUTOCONF=yes ONBOOT=yes DHCP_HOSTNAME=gollum.deepsoft.com # Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter DEVICE=eth1 BOOTPROTO=dhcp ONBOOT=yes HWADDR=00:04:23:72:b4:49 and network manager is happy to manage both network devices. > > > I presume that 192.168.1.0 is like your home or office network?

Though, I don't like and use NetworkManager and GUI tools, but I found/think, the GUI tool/applet available for/under GNOME is much better compared with the KDE variant.
