Configuring Servers</p></div>
<hr>
<div tabindex="0">
<p>The <strong>Config</strong> tab offers two levels of configuration: global, and interface. To configure at the global level, click the <strong>GLOBAL</strong> button to expand the <strong>Settings</strong> button (if it has not already been expanded). To configure an interface, click the <strong>INTERFACE</strong> button to expand the interface, and then choose the interface. The server also has the <strong>Services</strong> tab that provides access for service configurations. Lastly, it has the <strong>Desktop</strong> tab that provides tools to configure IP settings, open a host command line interface, and generate PDUs.</p></div>

<p class="MainHeading2">Global Settings</p>
</div>
<div tabindex="0">
<p>In the global settings, you can change the <strong>Display Name</strong> of the server. You may set the server to either automatically obtain IPv4 or IPv6 configurations by selecting the <strong>DHCP</strong> button or manually set the <strong>Gateway</strong> and <strong>DNS Server</strong> using the <strong>Static</strong> button. For IPv6, <strong>Auto Config</strong> will automatically configure the Gateway and DNS Server IP addresses and <strong>Static</strong> allows the data to be manually supplied.</p></div>
<p> </p><div tabindex="0">
<p class="MainHeading2">Algorithm Settings</p>
</div>
<div tabindex="0">
<p>In the <strong>Algorithm Settings</strong>, you can override the global Algorithm Settings by removing the check mark from <strong>Global Settings</strong> and then setting your own values for the <strong>Maximum Number of Connections</strong>, <strong>Maximum Number of Opened Sessions</strong>, and <strong>Maximum Retransmission Timeout in Milliseconds</strong>.</p></div>

<p class="MainHeading2">DNS Service Configuration</p>
</div>
<div tabindex="0">
<p>In the <strong>DNS</strong> service configuration, you can set up a DNS server to translate domain names with different types of resource records, which are basic data elements in the Domain Name System. Packet Tracer currently supports four different types of resource records: <strong>Address</strong> (<strong>A</strong>), <strong>Canonical Name</strong> (<strong>CNAME</strong>), <strong>SOA</strong> (Start of Authority), and <strong>NS</strong> (Name Server). An <strong>Address</strong> (<strong>A</strong>) record is the most common type of resource record where its core functionality is to map a hostname to an IPv4 address. A <strong>CNAME</strong> record is used to specify that a domain name is an alias of another, canonical domain name. An <strong>SOA</strong> record is used to specify authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, and several timers relating to refreshing the zone. An <strong>NS</strong> record is used to delegate a DNS zone to use a given authoritative name server.</p>
<p>To add a resource record, enter the <strong>Name</strong> of the resource record, select a <strong>Type</strong> of resource record, and then enter all required fields pertaining to the resource record such as <strong>Address</strong> for A Record, <strong>Host Name</strong> for CNAME, or <strong>Server Name</strong> for NS Record and then click <strong>Add</strong>. To modify an existing resource record, select the resource record from the list, edit the fields you want to change, and then click <strong>Save</strong> when you are done. If you want to remove a resource record, just select the resource record from the list and click <strong>Remove</strong>.</p></div>
