First your going to need to install IPTables:
Gentoo: emerge iptables   (Must be  Root to use/install iptables)
Ubuntu/Debian: sudo apt-get install iptables

Then edit your .bashrc file and add the following

alias blockedips="iptables -L"
alias blockip="iptables -I INPUT -j DROP -s "
alias unblockip="iptables -D INPUT -j DROP -s "

Reload your .bashrc by running source .bashrc and you should then be able to run the commands below

blockedips - Will Show all Blocked hosts
blockip IP-HERE - Will Block that ip
unblockip IP-HERE - Unblocks that ip

echo 'export HISTTIMEFORMAT="%h/%d - %H:%M:%S "' >> ~/.bashrc

Then reload your .bashrc

source ~/.bashrc

Now when you run history you should get a output similar to the one below

   502  Aug/12 - 13:48:31 tail -f /home/duffy/log/access.log
  503  Aug/12 - 13:49:01 echo hello
  504  Aug/12 - 13:49:24 more /var/log/syslog

Some other bash history tips

1. The best way of finding something quickly in your bash history is simply by pressing ctrl+r and then typing out the start of the command it will auto complete it with any matches found in your bash history
2. If you don't want to save duplicate commands in your bash history simply add export HISTCONTROL=ignoreboth to your .bashrc

   echo 'export HISTCONTROL=ignoreboth' >> ~/.bashrc

3. If you want to change the lenght of history add export HISTSIZE=1000 to your .bashrc

   echo 'export HISTSIZE=1000' >> ~/.bashrc

curl -u user:password -d status=”Your status message” http://twitter.com/statuses/update.xml

Just simply replace user with your username password with your password and Your status message with the content of your latest tweet

First, you should get NTP installed.

apt-get install ntp ntpdate

Next, just in case, make a backup of your already configured time.

mv /etc/localtime /etc/localtime-backup

Then we start to go into the process of getting the new local time file. We do this by going to /usr/share/zoneinfo.

cd /usr/share/zoneinfo

Once you reach this folder, there should be a list of folders of different countries. Go to the directory that you are located in. In this case, I am going to choose America.

Once you are in the folder of your country, there should be a bunch of cities that are in your country. Pick the closest city in your timezone. For example, I would choose Chicago. Then run the following command, changing, of course what needs to be changed to fit your needs.

ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime

Once you execute that command, the local time should be all set! To see the time on the machine, simply type "date" in the command line.

I hope this tutorial can be useful for you!

You can find the official list of modules here.

First step is to login to the server via SSH and go to the folder where UnrealIRCd is. Then you must go to the "src/modules" directory.

cd src/modules

Then, of course, you must download the file into the folder.

wget modulelinkhere

Usually, it will download a .tar.gz file, which you can extract by doing:

tar xfz filename.tar.gz

Sometimes the actual module file (in the format of modname.c) is in a folder, which you can easily get into the "src/modules" folder by moving it.

cd ModnameFolder
mv modname.c ../

If the .tar.gz opens as just a module file and not a folder, you can ignore the previous step.

The next step is to go back to the main UnrealIRCd folder

cd ../../

To compile the module run the following:

make custommodule MODULEFILE=modulename

Then after that is done, do the final step of compiling:

make install

But before you start anything you must edit the unrealircd.conf

nano unrealircd.conf

There is a part close to the top that has something like this:

loadmodule "src/modules/commands.so";
loadmodule "src/modules/cloak.so";

Under the last loadmodule, you put your newly compiled module in there.

loadmodule "src/modules/moulefile.so";

After that, your all done! All you have to do is rehash Unreal:

./unreal rehash
