Yes, I do happen to have 128-bit WEP enabled (it is a little bit better then nothing at all) with MAC filtering on my wireless router. I have the WEP key as line entry in my ifcfg-wlan0 file and not as a separate file;

TYPE=Wireless
DEVICE=wlan0
HWADDR=
BOOTPROTO=none
IPADDR=192.168.49.62
NETMASK=255.255.255.0
GATEWAY=192.168.49.10
DHCP_HOSTNAME=Aspire5100
DOMAIN=
ONBOOT=yes
ONHOTPLUG=no
USERCTL=yes
IPV6INIT=no
PEERDNS=no
ESSID=
CHANNEL=3
MODE=
RATE=
KEY=673CDE3ACEFACA8DF5DE247821

I did mangle my key.

Sorry, was at work. I have tried putting an extra line in the ipcfg-eth1 (me wireless device). Host not found.

KEY=06b9cd8f7g3rt8f6w892395c9s

But the moment I delete that and remove the wifi security from the router, the connection's fine.

I am using

[root@localhost network-scripts]# uname -a
Linux localhost.localdomain 2.6.9-22.EL #1 Mon Sep 19 18:20:28 EDT 2005 i686 i686 i386 GNU/Linux
[root@localhost network-scripts]# cat /etc/redhat-release
Red Hat Enterprise Linux WS release 4 (Nahant Update 2)

if thats any good. have you ever implemented WPA?

Cheers though

First, this looks like an ascii(plain text or string key); KEY=06b9cd8f7g3rt8f6w892395c9s
judging by the g,r,t and other characters beyond f and by the fact that they are lower case.

If true the it should looks like; KEY=s:06b9cd8f7g3rt8f6w892395c9s

Second my wireless router firmware does not support WPA so no I have not implemented WPA.

Third you should consider updating RHEL4 update 5 is out.

and sorry the key was mangled, only characters differ though.

i did try that as well..KEY=s:

didnt work, i also came across some articles ask=sking me to get a WPA supplement when a encryption is involved.

However, I am considering updating to RHEL 5.
I must confess that I am a newbie to linux, a mate's got "Redhat Enterprise Linux 5 Server (5 CD's) x86"- can these discs be used to install a workstation on me laptop?

Cheers for all the help.

There is no real significant difference between running MAC filtering and MAC filtering with WEP encryption as WEP is easily crack in a matter of minutes(2 or less in most caes). The primary reason I have it enabled is to make sure my wireless connection is to my router and not any one else's in the area.

You do realize that if you install RHEL5 that you will noy be able to install any updates without registration (entering a valid key for RHN), a better solution is to install RHEL5 AS then switch over to using CentOS5 instead. This only takes a few minor changes;

Hmm...I see. Thats makin me think coz I am not yet ready to register. I may want to try a few more distros. But its just that I have used SCO Unix ages ago and have a liking for RHEL.
When you say REHL5 'AS', what exactly do you mean? Sorry for being a noob but as far as I know, its REHL5 Server and Desktop. Also the links you gave me were pretty informative. I look forward to making use of the knowledge. Cheers.

Red Hat comes in a number of flavors so to speak, AS is Advanced Server then there is ES (Enterprise Sever) all the way down to a "Desktop" version now. CentOS is a 100% binary compatible "free clone" of RHEL AS/ES.

Got you now. Only question is, will it format me HDD or just the partition?
Coz I am on a dual boot at the moment and I need windows as well for some reason.

One can choose how and where to install CentOS or RHEL during the installation process, see:

http://www.redhat.com/docs/manuals/e...setup-x86.html

One can 'wipe and load' the entire hard-drive, 'wipe and load' just the Linux partitions or create new partitions for installation if blank unformatted hard drive space is available.

That makes things pretty clear. You mentioned about CentOS earlier... Would you recommend installing redhat 5 and then changing it to CentOS or installing a clean copy of centOS?

Also a personal question, if you don't mind. Are you using RHEL or CentOS, Which one do u prefer, why? I have checked centos.org, they are doing some great work. respect.

I use and work with CentOS5, RHEL5 and Scientific Linux 5 all three are basically the same as both CentOS and SL are 100% binary "free clones" of RHEL. One can install RHEL5 without registering a key but cannot get updates online from RHN. Or one can use the repos from CentOS to maintain/update RHEL5 or just use CentOS5 from the get go. The same thing also applies for SL.................

Choices, Choices got to love choices!!!!

In any case which ever version I use I do make adjustments and tweaks from the default packages. For example I build and use a custom vanilla kernel from kernel.org;

$ uname -a
Linux Aspire5100 2.6.22.5 #1 Thu Aug 23 06:43:54 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

$ cat /etc/*release
Red Hat Enterprise Linux Client release 5 (Tikanga)

And install things which are not part of the official package choices;

$ rpm -qa firefox thunderbird kdebase
kdebase-3.5.7-13.fc7
thunderbird-2.0.0.5-1.fc7
firefox-2.0.0.5-1.fc7

Hi, the connection finally works with dhcp, mac filter and wep 128 bit encryption!

I am using
[jig@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.18-8.1.8.el5 #1 SMP Tue Jul 10 06:50:22 EDT 2007 i686 i686 i386 GNU/Linux
[jig@localhost ~]$ cat /etc/*release
CentOS release 5 (Final)

You won't beleive the mistake i'd been making all the way.
Remember the key I was typing in keys-eth1 file. The letters were in lower case. When I change it to upper case it works bang on!

[jig@localhost ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Wireless
DEVICE=eth1
HWADDR=00:13:ce:24:87:1c
BOOTPROTO=dhcp
GATEWAY=192.168.1.1
ONBOOT=yes
ONHOTPLUG=no
USERCTL=yes
IPV6INIT=no
PEERDNS=no
ESSID=Lucifer
CHANNEL=11
RATE=Auto

The nameserver file as you said. And the keys-eth1 file KEY=0A972BC33473CFFEAC (mangled key)
Thanks a lot Lenard!

Also the aircrack thing wont work with ipw2200 wireless card. So I cant be a sniffer, it needs prism or artheos cards..Thanx a mill buddy

Glad to hear you figured it out and that it is working. You learned a lot including the fact that passwords and keys are case sensitive.
