You ing moron, enough with the random replies about conspiracy

everyone suggested they drop into a shell and run simple commands. You
fail, again.

Thanks for all the replies.

I cannot see another kernel in /boot/*, and I want to go home now,
before I have coffee and possibly create another one :)

We have recently added CPU's to this machine as well.

I have not tested the RAM yet, because I can't easily take this
machine off line.

I will see.

gotten far too involved long ago and has taken the helm as the local
kook. Sort of like the movie 21 where the guy gets caught up in
gambling once he breaks out of the math rules that he should have kept

Wireless network setup

iwconfig is for setting wireless parameters of the link level,

No. It's all configured in userspace.
 

To use WPA you need wpa_supplicant. It comes with all major Linux
distributions.

Here's a quick guide, for how to do it completely manually:

Linux doesn't mandate a specific naming convention for network
interfaces, driver writers can choose anything they want. So
first find out which your wireless interfaces are, by simply
typing iwconfig on a root shell.

On my laptop (narfi) this gives:

iwconfig
lo no wireless extensions.

sit0 no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11abgn ESSID:""
Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated
Tx-Power=15 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

pan0 no wireless extensions.

Not surprising the interface "wlan0" is a wireless interface.

If there's no interface showing up with wireless extensions, then you
* don't have the driver loaded
or
* your installtion misses the firmware files
or
* your wireless hardware is not (yet) supported by Linux

If you were about to connect to a public, unprotected access point,
you would use iwconfig to setup the interface e.g.:

iwconfig wlan0 ssid "HotSpot" enc off

To use WPA you must configure your wpa_supplicant. You can either do
this by using its GUI "wpa_gui" - this is quite self explanatory, I
don't think I've to explain that one, wpa_supplicant must be started
before starting wpa_gui though.

Or you're creating the file /etc/wpa_supplicant/wpa_supplicant.conf
by hand. Use this template:

--- BEGIN /etc/wpa_supplicant/wpa_supplicant.conf ---

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0

network={
ssid="..." # your SSID
proto=WPA2 WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="..." # put your WPA password here
}

--- END ---

You can then start wpa_supplicant on the wireless interface:

/sbin/wpa_supplicant -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf -B -iwlan0 -P/var/run/wpa_supplicant-wlan0.pid

wpa_supplicant will background. To see what's going on start wpa_cli.

Once the connection is made you can configure the address of your interface.
In case of DHCP it's easy as, depending on which of dhcpcd or dhclient are
installed.

dhcpcd wlan0

or

dhclient wlan0

For static IP configuration use

ip addr add $ADDRESS/$NETBITS dev wlan0
ip route add default via $ROUTER dev wlan0
rm /etc/resolv.conf.new
for NS in $NAMESERVERS ; do echo "nameserver $NS" >> /etc/resolv.conf.new ; done
mv /etc/resolv.conf.new /etc/resolv.conf

e.g.

ip addr add 192.168.1.123/24 dev wlan0
ip route add default via 192.168.1.254 dev wlan0
rm /etc/resolv.conf.new
for NS in 192.168.1.253 192.168.1.252 ; do echo "nameserver $NS" >> /etc/resolv.conf.new ; done
mv /etc/resolv.conf.new /etc/resolv.conf

Of course all major distributions provide you with a convenient
configuration interface abstracting away all those gory details,
however this is specific to each distribution.
Just RTFM of the distribution you use.

Yep, and if everyone that knows better ignores him, he is free to post
what he wants without being called on it. Granted, we could just call
him on the "technical" flaws of his rants, but to the unknowledgable
viewer of the thread, they have no idea who is right or wrong, so I
think it's relevant to point out that he's a nut, and when everyone
calls him on his crazy, clueless rantings (and we all have been), it
really puts it out there for everyone to see. Not because we're
grouping up against him, but because we all know better and are tired
of it. I think that works well, and given Sid's history, the entire
group standing up against his bull, is the only thing that will
make him give up and go away (even if it's not soon enough). It's
worked in other groups with him (not that he won't be back under a new
name).
 

Exactly. Idiot's always take their own frustrations out on the wrong
things and the wrong people.
 

Yep, and it's always the complete wierdos like Sid that lack a clue, and
they are too stupid to realize their arrogance is misplaced. Something
is just broken in his brain.
 

Right, I've seen it happen in another group or two. Usually though,
it's by the regulars there that think they control the place and a few
of them stick together and try and act like they speak for everyone.
Instead of anyone calling those regualr trolls on their bull,
people just felt better passing blame around for anyone that was
involved (regardless if you were just clarifying or defending
yourself), and it just allowed those trolls to take over the group
entirely. They still run the place, but I don't just ignore them
silently and arguing correctness with a troll will only drag out the
issue indefinitely, so I take a different approach. But, you know
what? They always give up and leave me alone, and any intelligent
poster will not hold it against me, else everyone can just be
complacent allowing the troll to run the place.
 

Oh, I know! :-)

I went to do some 'surfing' with it and was completely baffled by the
truncated display for a bit. Setting the rows back to 49 fixed the
problem.
