But another cool tool I found is synergy which combines my old notebook and my dual head workstation at work.

Simple to set up:

* apt-get install synergy

* create on the server /etc/synergy.conf

* section: screens
moped:
gOnZ:
end
section: links
moped:
left = gOnZ
gOnZ:
right = moped
end

* start the server on (my machine is called moped ) with: synergys –config /etc/synergy.conf &

The client got to do nearly nothing:

* ssh -f -N -L 24800:localhost:24800 moped;
* synergyc -n gOnZ localhost

Done – from now on I share my keyboard and mouse on three screens

Adding my MacBook to the right of the whole setup is done quick as …. and will come soon

I am invited to show my skills at the LPI 101 exam – in the testing center Auldhouse Computer Training. But I still forget a lot of simple stuff that I will collect here to make myself mental notes:

In the Bash shell, entering !! has the same effect as which one of the following?

• Ctrl-P and Enter

Which of the following commands can be used to check an ext2 filesystem? Select three that apply.

• fsck /dev/hda5
• e2fsck /dev/hda5
• fsck.ext2 /dev/hda5

Carolyn has a text file named guest_list containing 12 lines. She executes the following command. What is the result?
# split -4 guest_list gl

• The lines of guest_list are evenly divided among new files glaa, glab, and glac.

An ext2 filesystem is configured with user quotas enabled. The soft limit is set at 100 MB per user, the hard limit is set at 110 MB per user, and the grace period is seven days. User bsmith already owns 90 MB of the data stored on the filesystem. What happens when bsmith writes a new file of size 30 MB? Select one.

• The write will continue until the hard limit of 110 MB is reached, after which the write fails and data is lost.

Which of the following commands displays the comments from a bash script? Select all that apply.

• sed ‘/^#/ !d’ /etc/rc.d/init.d/httpd
• grep ^# /etc/rc.d/init.d/httpd

(find and locate do not search the contents of files. /etc/passwd is not a script)

State the syntax to direct the standard output of cmd1 directly into the standard input of cmd2.

• cmd1 | cmd2

Which one of the following answers creates an environment variable VAR1, present in the environment of a bash child process?

• VAR1=”fail” ; export VAR1

(The variable must be set and exported. The semicolon separates the two commands.)

Which of the following directories must be part of the root filesystem? Select two of the following that apply.

• /etc
• /lib

(/etc, /lib, /bin, /sbin, and /dev must be in the / filesystem.)

Alex is currently working in a directory containing only one file, Afile1. What is displayed after the following commands are entered in bash?

# MYVAR=ls
# echo $MYVAR “$MYVAR”

• ls ls $MYVAR Afile1

(The first echo argument is unquoted and thus returns its contents, ls. The second is quoted with double quotes, which do not preserve the $, so it too returns ls. The third is quoted with single quotes, which do preserve the $, so it returns the string $MYVAR. The last argument is backquoted, which means that it returns the result of the command stored in $MYVAR. The command is ls, which displays the only file in the directory, Afile1.)

Which one of the following outcomes results from the following command?

• The SGID bit will be set for /home/software, in order to keep group membership of the directory consistent for all files created.

(The g indicates that we’re operating on the group privilege, and the +s indicates that we should add the “set id” bit, which means that the SGID property will be applied.)

What command can display the contents of a binary file in a readable hexadecimal form? Select one.

• od

(The octal dump program, when used with the -t x option, will output in hexadecimal notation.)

Which one of the following commands copies files with the .txt extension from /dir1 into /dir2, while preserving file attributes such as dates?

• cp -p /dir1/*.txt /dir2

(The -p, or preserve, option is required to retain dates.)

With a umask of 027, how is the initial mode set for a newly created file?

• 0640 (b)

(By default, files do not have the execute privilege, which rules out all responses containing odd numbers in the mode. They also do not by default have the sticky bit set, which eliminates response e. Response b is the result of masking initial bits 666 with umask 027, leaving 640, which is the same as 0640.)

Alex wants to protect himself from inadvertently overwriting files when copying them with cp. How should he go about this?

• Put alias cp=’cp -i’ in ~/.bashrc.
• or Put alias cp=’cp -i’ in ~/.bash_profile.

(cp should be aliased to the interactive mode with the -i option in .bashrc. .bash_profile normally doesn’t include aliases, but it will also work.)

Which one of the following is an accurate statement regarding this regular expression?

[^1-8A-Za-z]

• It matches 9, 0, and other nonletter and nonnumber characters.

With regard to the use of regular expressions to match text in a file, describe a metacharacter. Select one.

• Metacharacters aren’t used in regular expressions.

(A metacharacter is a special character that is used to modify and control the interpretation of literals. File globbing is generally considered distinct but very similar to the use of regular expressions.)

How can you query the RPM database for a list of all installed RPM packages? Select one.

• The query mode is required, which implies -q. The -a option in query mode yields all packages.

Which pair of dpkg options are equivalent and what do they do? Select one.

• -C and –audit; they search for partially installed packages.

What will happen when rpm is launched as follows?

rpm -Uvh file

• Provided that file is an RPM file, the -U indicates that an upgrade should occur. -h turns on hash marks.

When using xdm, which of the following files can be used to start a window manager? Select one.

• Xsession

How can you obtain a list of files contained in an .rpm file? Select one.

• rpm -qlp queries and lists files in the package.

Which of the following accurately describes the contents of the xdisp:1.0 DISPLAY environment variable? Select one.

• The system, xdisp, will display programs on the second display of its X server.

Which is not a valid dpkg installation command? Select one.

• b. Options -i (install) and -L (list installed files) are incompatible and don’t make sense together.

apt-get build-dep amanda-client; apt-get –build source amanda-client

because there are proved problems

$ ssh-add
Could not open a connection to your authentication agent.

Get around that, call the ssh-agent once

$ ssh-agent

$  ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-M6teDMsPGI/agent.720; export SSH_AUTH_SOCK;
SSH_AGENT_PID=721; export SSH_AGENT_PID;
echo Agent pid 721;

And define your enviriment with:

$ eval `ssh-agent`

After that ssh-add will ask for your passphrase for your private key

( You can check the correct settings with

$ set |grep SSH_
SSH_AGENT_PID=709
SSH_AUTH_SOCK=/tmp/ssh-1YQqIGygW7/agent.708 )

I was having problems getting iTerm to work well with irssi.. specifically.. using the alt/option key to swap between tabs in irssi. Alt wasn’t doing it..even when set to Meta or +esc. So I dug around and found this in some comments to someones post about needing a new term app.

If you’re on a Macbook(Pro) laptop, and using irssi with screen on a remote machine via ssh; heres what works (for me)

To switch between irssi windows (normally alt+1 etc.) – use;
Press Esc, let go – then press number, 1, 2 whatever

(To pageup/pagedown – use this keyboard sequence (must be in this order)

Press (and hold) Shift-key, now Press and hold fn-key, now with these keys pressed (in that order) – press the pageup (arrow up) or pagedown (arrow down) keys to pageup/down)

If your backspace key is acting as a ‘delete’-key in irssi in screen, Hit command+I, in terminal to bring up your window preferences, under the Keyboard settings, tick ‘Delete key sends backspace’ – that should fix that.

So, slightly more tricky on the laptop, but achievable none-the-less

Matt

Thanks, Matt

Who ever you are.

I decided towards the nice iTerm, to have tabs available and much more nice features.

I love Mac – download – double click – drag and drop -> USE! awesome..

Next toy to get advantage of the build in iSight (and use our land-line replacement) skype needed to be installed.

Mail and browsing tools are basic! Choice: Thunderbird and Firefox from the mozilla familie

To extract packages (in zip tar whatever format) I selected the free tool stuffit.

Vlc is my video tool (with vlc browser plug-in)

To get connected to my office OpenVPN client tunnelblick (what is a awesome word for a VPN prog, when you are familiar with the german language ).

Yeah – getting closer to all the installation stuff you need.

But what a lot of people need, is a application that handels there .doc’s .ppt’s etc.. That counts for me aswell.

My choice to go around a Micro$oft applications was for NeoOffice (I thought about OpenOffice but asked a bit around in the circles of mac hackers – and it looks like everybody is using Neo).

It’s a simple step: Download the Package from Neooffice.org.

NeoOffice is not based on X11 like Openoffice what makes it easy to set up, go ahead and install the NeoOffice package (double-click and use) – should just work!

FUN! The office package is in place.

Opening the box was ike cristmas!! I ripped off the cover and there it was – This cuite little MacBook.
I took it out to start the Install (strange – The MacBook was delivered in sleep mode?) filled out the questions asked and here we go – A fresh 10.4.9 insallation!!

Yeah..

Now the install festival can start.

sudo /usr/sbin/nvram boot-args=”-v”

The next time you boot your Mac, it boots in verbose mode.

To turn this setting off, use the command:

sudo /usr/sbin/nvram boot-args=

To boot in single-user mode , hold down -S as you start the computer. In single-user mode, your filesystem is mounted as read-only, which limits what you can do. Single-user mode should generally be used only to repair a system that has been damaged (for example, see “Restoring the Directory Services Database” in Chapter 5). Unlike with other Unix systems, we do not suggest that you use single-user mode to perform fsck repairs manually. Instead, restart your Mac and boot from Tiger’s install DVD (hold down the C key as your Mac starts up), and then run the Disk Utility (Installer Open Disk Utility) to repair a problem disk volume.

As a Sysadmin at Catalyst I am allowed to get a Company Notebook and that is My MacBook what i have chosen.

I will keep track in this category what I am planing to install on this nice one.

In theory I will load so much crap on the OS X 10.4 version that I know what I want to make a clean 10.5 Leopard installation.

Today the MacBook will be delivered and I can start the installation festival.

Track and trace the parcel with: SJ053020537NZ you can follow it where and when it is delivered
