<h2>
Quick guide
</h2>
<p>
Set up two virtual computers - SimpleArbiterDhcp and FileServer.
</p>
<p>
Make sure that the directory /srv/nfs/ERLbbBrT on FileServer is accessible
over NFS and over SMB under the sharename urania-03.
Set the SMB server name to zarptica-32.
</p>
<p>
SimpleArbiterDhcp should have write access to /srv/nfs/ERLbbBrT over NFS.
</p>

<li>
Set up a DHCP server
<ol>
<li>
<span id="code">
apt-get update
</span>
</li>
<li>
<span id="code">
apt-get install isc-dhcp-server
</span>
</li>
<li>
The server will not start (error
<span id="code">
Starting ISC DHCP server: dhcpdcheck syslog for diagnostics. ... failed!</span>)
, configure 3 files:
<ul>
<li>
In /etc/network/interfaces set static IP for eth1 on which the DHCP server will be running,
e.g.:
<p id="code">
auto eth1<br>
iface eth1 inet static<br>
address 192.168.1.10<br>
netmask 255.255.255.0<br>
network 192.168.1.0<br>
broadcast 192.168.1.255<br>
</p>
</li>
<li>
In /etc/default/isc-dhcp-server:
<p id="code">
INTERFACES="eth1"
</p>
</li>
<li>
In /etc/dhcp/dhcpd.conf configure the subnet properties,
e.g.:
<p id="code">
authoritative;<br>
default-lease-time 600;<br>
max-lease-time 7200;<br>
<br>
subnet 192.168.1.0 netmask 255.255.255.0 {<br>
range 192.168.1.100 192.168.1.200;<br>
option routers 192.168.1.10;<br>
option domain-name-servers 193.2.1.66, 8.8.4.4;<br>
<br>
host SimpleArbiter {<br>
hardware ethernet 08:00:27:A2:FB:B4;<br>
fixed-address 192.168.1.180;<br>
}<br>
}<br>
</p>
</li>
</ul>
</li>
</ol>
</li>
<a name="nfs"></a>
<li>
Set up a NFS server
<ol>
<li>
apt-get install nfs-kernel-server
</li>
<li>
Determine the rules in /etc/exports, e.g.:
<p id="code">
#privileges for SimpleArbiterDhcp<br>
/srv/nfs/ERLbbBrT 192.168.1.180(rw,sync,insecure)<br>
/srv/nfs/ERLbbBrT 192.168.1.0/24(ro,sync,insecure)<br>
</p>
</li>
<li>
Change the owner of the directory and files in it:
<span id="code">chown student /srv/nfs/ERLbbBrT</span>
and similary for all the files in shared directory. The owner should not be root.
</li>
<li>
Run command
<span id="code">exportfs -rv</span>
to export file systems
<p>After that run
<span id="code">services nfs-kernel-server restart</span>
</p>
</li>
<br>
</ol>
</li>
<a name="smb"></a>
<li>
Set up SMB server
<ol>
<li>
<span id="code">
apt-get install samba
</span>
</li>
<li>
Create directory urania-03, npr.:
<p id="code">
mkdir /home/student/urania-03
</p>
</li>
<li>
Edit configurations in /etc/samba/smb.conf, add at the bottom of document, e.g.:
<p id="code">
[zarptica-32]<br>
path = /home/student/urania-03<br>
available = yes<br>
valid users = tester<br>
read only = no<br>
browseable = yes<br>
public = yes<br>
writable = yes<br>
</p>
</li>
<li>
Restart Samba:
<span id="code">
service samba restart
</span>
</li>
<li style="list-style-type:none;">
<p>
Test the syntax of smb.conf file with command
<span id="code">
testparam
</span>
</p>
</li>
<li>
Add users:
<p>
In order to define passwords for Samba users they have to exist as system users.
<p>
Use command
<span id="code">
useradd USERNAME --shell /bin/false
</span>
to create user with a disabled account and without home directory, e.g:
<p id="code">
useradd tester --shell /bin/false
</p>
</p>
<p>
Define Samba password for your user:
<p id="code">
smbpasswd -a tester
</p>
</li>
</ol>
</li>
</ol>
</li>
<br>
<a name="client"></a>

<h3>
Client SimpleArbiterDhcp
</h3>
<ul type="disc">
<li>
NFS: run the command as root
<span id="code">
mount -t nfs nfs_server_ip:shared_dir dest
</span>, e.g.:
<p id="code">
mount -t -nfs 192.168.1.10:/srv/nfs/ERLbbBrT shared
</p>
</li>
<li>
SMB:
<ol>
<li>
Install Samba client as root:
<p id="code">
apt-get install sambclient<br>
</p>
</li>
<li>
Connect to SMB server::
<p id="code">
smbclient //192.168.1.10/zarptica-32 - U tester
