18. First Login

Now we are in our fresh Arch installation.
Login as root.
From now on and till we have a running desktop be careful since root may destroy the system if anything wrong happens.
Remember to use the Tab button since it auto completes folders and file names.
Type: 

cd /
clear

19. Users and Groups Configuration

First we create our user which we will normally use in our system. Use only small latin letters with no spaces.

Let’s say it will be called nioubis. Type the following: 

useradd -m -G users,wheel,audio,video,optical,storage,camera,floppy -s /bin/bash nioubis

Now we must select a password for our user: 

passwd nioubis

Be carefull. Do not use spaces. The password should be difficult for other to be found. Of course you shouldn’t forget it!

20. Testing Local Repository 

Here we are going to test if the local repository we previously created works fine. Type:

pacman -Sy
update-local-repo custom <αρχιτεκτονική>
pacman -Sy
 

If you will get a message that a new version of pacman has be found, when prompted answer YES to update pacman first. When it’s installed type:

pacman -Su

Then open:

nano /etc/makepkg.conf

And search for the line:

export MAKEFLAGS="-j2"

 
Here you can see a number after j at the end. You should change this number to the number of your system CPU cores plus one. If you have a system with an Intel HyperThreading processor you should double this number before adding 1.
For example if your computer is a server with 8 Opteron cores you should use 8+1=9.

MAKEOPTS="-j9"

 
Save and exit nano.

Press Ctrl+Alt+F2. Now login again.
This time we will login not as root but as a user.
So in the login prompt type the user’s name you have created before as well as his password.

Next type:

cd ~
nano .bashrc

Add the following line to this file:

alias nicepac="nice -n 19 makepkg"
alias manualpac="nice -n 19 makepkg -d"

Save and exit nano.

Type:

exit

Press Ctrl+Alt+F1 to get back to the previous login.

If you want to use your Arch installation as a server you should also install the following applications.

pacman -S nano screen openssh

Go to:

cd /etc/ssh
cp sshd_config sshd-config-backup

And type:

nano /etc/ssh/sshd_config

Here we are intrested in the following lines:

PermitRootLogin yes
RSAAuthentication yes
PubkeyAuthentication yes
#IgnoreRhosts yes
RhostsRSAAuthentication no
HostbasedAuthentication no
#IgnoreUserKnownHosts no
PermitEmptyPasswords no
ChallengeResponseAuthentication no
#PasswordAuthentication yes
UsePAM no

Be careful here. Some lines may already exist, some others may have a different value (yes or no) and others might be commented or not.

Save and exit nano.

cp sshd_config sshd-config-root-login
cd /

Then:

nano /etc/rc.conf

We are intrested for the line DEAMONS=:

We had left it like this:

DAEMONS=(syslog-ng network netfs @crond)

We will make it like this:

DAEMONS=(syslog-ng network netfs @crond @sshd)

Save and exit nano.

Moreover open those two files with nano and make sure that all the lines are commented, they should start with a "#".

- /etc/hosts.allow
- /etc/hosts.deny

Save and exit nano.

Finally type:

/etc/rc.d/sshd start

Now go to your other pc and make sure it is connected in your lan. You may access your server like this:

For Windows NT-Class open PuTTY and type:

root@neo

Give your root password and press Enter.

For *nix-like type:

ssh root@neo

Give your root password and press Enter.

Answer yes that you "trust" neo.

Finally type:

screen -i
