    Q: How would this script be ammended to my existing 'rc.local' and made 'root:root' & 'executable'?

    Code:
    #!/bin/bash
    #
    # rc.local
    #
    # Start local services after hardware detection
    
    SERVICES="cups"
    
    for i in $SERVICES; do
     [ -x /etc/init.d/"$i" ] && /etc/init.d/"$i" start >/dev/null 2>&1
    done
    
    exit 0
    THX!

    Greetings, luther.

    I'm using Knoppix 7.2 and just the following in rc.local now:
    sudo iwconfig wlan0 txpower 5mW rate 54M key (key code) essid "(essid name)"
    Time to browser on-line is 50 seconds, same as when using Win7 on this laptop.

    FWIW.
    1. sudo is not really necessary as Forester has pointed out.
    2. Klaus K has changed the 7.2 boot up process somewhat to improve boot time,
    but I'm not aware just where and how.
    3. The reduced transmit power was a suggestion of Klaus K's to counter-act
    local wifi interference. I don't know if this helps on time to connect
    but it seems to improve the frequent disconnect situation here.
    4. It's quite likely Network Manager has improved as well since this thread
    was initiated.

    In answer to you question, I suggest the following:

    As root call up leafpad and edit /etc/rc.local
    by adding the following line just before the "exit 0" line:

    iwconfig (wifi's device name) rate 54M key (router key code) essid "(router essid name)"

    If that doesn't improve things, then this might be one more reason
    to benefit from upgrading to 7.2.

    utu,

    The line needed to be rooted for the LED to fire, but wasn't able to connect. Therefore, resorted to 'udhcpc' that was installed from synaptic:




    Code:
    knoppix@Microknoppix:~$ sudo iwconfig wlan0 essid mynetwork
    knoppix@Microknoppix:~$ sudo iwconfig wlan0 key 6789abcdef
    knoppix@Microknoppix:~$ sudo udhcpc -b -i wlan0 -x hostname:Microknoppix -p /var/run/udhcpc.wlan0.pid
    udhcpc (v1.20.1) started
    Sending discover...
    Sending discover...
    Sending select for 192.168.0.14...
    Lease of 192.168.0.14 obtained, lease time 86400
    /etc/udhcpc/default.script: Resetting default routes
    SIOCDELRT: No such process
    /etc/udhcpc/default.script: Adding DNS 8.8.4.4
    /etc/udhcpc/default.script: Adding DNS 8.8.8.8
    knoppix@Microknoppix:~$
    'udhcpc' freezes knoppix 7.0.3 on my older hardware, giving credence to this post to your 'old' thread.
    'udhcpc' has a '-syslog' switch, but is useless when it causes knoppix to freeze!
    luther

    PS. 7.0.3 has been an excellent PC repair tool and hate to part w/it!

    I didn't make it clear that in Knoppix 7.2, I've gone back to using Network Manager.
    I now use only the line I quoted earlier to boot my system.
    You are quite right that the line itself must be issued by root.
    This is, or may be, done by /etc/rc.local which has root:root ownership.

    The programs you like in 7.03 may be available in 7.2 as well.
    I'll take a look at my Synaptic to see if that's so, if you'll name it (or them).

    utu,

    Give this synaptic front end app a try and see if 7.2 is compatible with ALL its features:


    Software-Center
    .

    7.03 had a few problems with it.
    e.g., 4gig persistance.

    I note that my version of Synaptic, without being
    itself upgraded from the initial 7.2 values,
    indicates software-center 5.1.2debian3.1 Utility
    is available for download.

    I have no experience with using software-center
    and no current motivation to use it. Perhaps you
    can tell me what it's good-for.

    I use reiserfs persistence, but have no current need
    for 4 G's of it.

    software-center is where Update Manager resides. It's a memory hog and if it's not wise to update knoppix iso's, shouldn't it be blacklisted?

    Greetings again, luther.

    You've obviously got the right idea about (not) trying to upgrade Knoppix this way.
    Blacklisting software-center might be in order on this principle, but
    perhaps a little heavy-handed for some of the more experienced Knoppixers,
    who know how to handle the 'dependencey hell' aspect which may arise.
