How to install wireless:

Keys:

Install the Linksys drivers from the cd or from the web.
SSID is phobos_ch
Channel number is 6
We are now using 128 bit WEP; the key generator for Windows is still "phwless", but for Linux and probably Mac you'll need the direct hex keys.  They are:

4C:F0:41:49:51:45:DD:E9:A0:A3:13:46:7B

(you probably need to enter it without the colons)

Mac OS X 10.3 instructions

  1. Choose WEP 128-hex from the pulldown menu.

  2. Enter the key listed above without the colons

Out-of-date Linux Instructions

  1. Verify you have linux kernel 2.2.12 or higher:
    $ uname -a
    Linux baz 2.2.17-14 #1 Mon Feb 5 17:53:36 EST 2001

  2. Verify you have the kernel-source rpm installed:
    $ rpm -q kernel-source
    kernel-source-2.2.17-14

    If not, you need to seek out the kernel-source rpm that matches your kernel version. If you don't have the redhat CD, you can get the rpm via FTP from

    phyppro1.phy.bnl.gov

    in the following directory (substitute your RedHat version for 6.1):
    /pub/redhat-pub/redhat/linux-6.1/en/os/i386/RedHat/RPMS

    The file is named kernel-source-2.2.x-y.rpm, where 2.2.x-y should match your running kernel.  (If you've upgraded your kernel, try /pub/redhat-pub/redhat/linux/updates/6.1/en/os/i386)

    After obtaining the kernel-source rpm, install it as follows:
    $ cd ~
    $ su root
    # rpm -ivh kernel-source-2.2.x-y.rpm

  3. Configure the pcmcia source inside the kernel
    # cd /usr/src/linux
    # cd pcmcia-cs*
    # pwd

    Keep track of this directory; we will need it in Step 5.

    # ./Configure
    Linux source directory: /usr/src/linux
    Defaults for:
       Alternate target install directory
       Module install directory
       C compiler name
       Linker name
       Compiler flags for debugging
       Trusting versions of card utils
       32-Bit support

    Kernel-specific options: 1 (read from the currently running kernel)

      Defaults for the rest

    # cd ~

  4. Obtain the wlan tarball from here and uncompress

    # tar xfvz linux-wlan-ng-0.1.8-pre13.tar.gz

  5. Configure the wlan drivers
    # cd linux-wlan-ng-0.1.8-pre13
    # make config

    Linux source directory: /usr/src/linux
    pcmcia-cs source dir: enter the directory you noted in Step 3.
    Use the defaults for the other questions.

  6. Compile the package and install
    # make all
    # make install
  7. Obtain the following files
    wlan-ng.opts, put it in /etc/pcmcia
    ifcfg-wlan0, put it in /etc/sysconfig/network-scripts

  8. Edit /etc/sysconfig/network-scripts/ifcfg-wlan0, and change 
    IPADDR="127.0.0.1" to your IP address 

  9. Plug in pcmcia card.
  10. Restart pcmcia services (you only need to do this the first time)
    # /etc/rc.d/init.d/pcmcia restart

For Apple Airport (provided by Frank Wolfs):

  1. Open TCP/IP control panel and use the following settings:

    connect via: Airport

    make sure the check box in front of "Use 802.3" is not checked

    Configure: Manually

    Enter the information for a fixed IP:

    IP Address: 130.199.???.???
    Subnet mask: 255.255.254.0
    Router address: 130.199.176.24
    Name server addr: 130.199.1.1
                              130.199.128.31
    Implicit Search Path
    Starting domain name: chm.bnl.gov
    Ending domain name:
    Additional Search domains:

  2. Close the TCP/IP control panel.  You will be told that your changes will affect currently established TCP/IP services.  Click OK.
  3. Open the Airport application (should have been added to the Apple menu during installation).
  4. If details about the settings are not show below the "Status" information, click on the triangle in front of "Setting in order to make them visible.  The only setting that needs to be changed is the choice of network:

    Choose network: phobos_ch

    After you select the counting house network, you will be asked to enter the network password.  For the counting house network, you need to enter the 10 character Key 1 (without the ":"s, preceded by a single $).  Thus, the required password was $8AF997336B for 64 bit; see the Keys section for the 128 bit.

  5. That is all.  You should now be connected to the network.
