Dell ThinOS 2402 Administrator’s Guide

Configure the general settings

1. From the desktop menu, click System Setup > Network Setup.
   The Network setup dialog box is displayed.
2. Click the General tab, and do the following:

   

   NOTE:If network interfaces are in the same subnet, connection to the same subnet is prioritized last by the interface to fetch the IP address. Connections to the other subnets are prioritized in the order ENET0, ENET1, and WLAN.
   1. To set a default gateway, select the type of network interface from the Select Network Interface as the Default Gateway drop-down list.
      ThinOS supports the dual IPv6 network interface. The following network combinations are supported:

      • Wired connection 1 + Wireless connection 1
      • Wired connection 1 + Wired connection 2

      NOTE: The limitation of the dual network is that the device cannot automatically determine which connection to use among the two.
   2. Use Static Name Servers—By default, this check box is not selected, and the thin client fetches the server IP address from DHCP. To manually assign the static IP addresses, select the Use Static Name Servers check box and do the following:
      NOTE:If name servers are changed, the details are displayed in event logs. In dynamic mode, the DNS can be merged from Ethernet and wireless, or from Ethernet 0 and Ethernet 1.

      NOTE:From ThinOS 9.1.3112 onwards, you can upload the host file using the Wyse Management Suite policy settings or the Admin Policy Tool. To upload the file, go to Advanced > System Settings > Device Settings from the Wyse Management Suite policy settings or the Admin Policy Tool, and click Browse... next to Select Host File. ANSI or UTF-8 encoding is supported, and the maximum supported file size is 10 KB.
      1. Enter the URL address of the DNS domain in the DNS Domain field.
         NOTE:From ThinOS 9.1.5067 onwards, you can use multiple DNS domain suffixes. Use ; to separate values.
      2. Enter the IP address of the DNS server in the DNS Server field.

         However, the use of DNS is optional. DNS enables you to specify remote systems by their host names rather than IP addresses. If a specific IP address (instead of a name) is entered for a connection, it is used to make the connection. Ensure that you use the DNS domain and the network address of an available DNS server. The function of the DNS domain entry is to provide a default suffix that is used to resolve the name. The values for these two fields may be supplied by a DHCP server. If the DHCP server supplies these values, they replace any locally configured values. If the DHCP server does not supply these values, the locally configured values are used.

         On ThinOS, error tips are displayed when you set an invalid DNS server. A window with the error message is displayed when you click save the invalid DNS server.

         NOTE:You can enter the server addresses, each separated by a semicolon. The character limit is 256. The first address is for the primary DNS server, and the rest are secondary DNS servers or backup DNS servers.
   3. Enter the IP address of the WINS server in the WINS Server field.
      NOTE:Only one WINS server is supported.

      However, the use of WINS is optional. You must specify the network address of an available WINS name server. WINS enables you to specify remote systems by their host names rather than IP addresses. If a specific IP address (instead of a name) is entered for a connection, it is used to make the connection. These entries can be supplied through DHCP, if DHCP is used. DNS and WINS provide essentially the same name resolution. If both DNS and WINS are available, the thin client attempts to resolve the name using DNS first and then WINS. You can enter a single WINS Server address.

   4. Enter the digit multiplier of 30 s in the TCP Timeout box to set the time-out value of a TCP connection. The value must be either 1 or 2 which means the connection time-out value is from 1 x 30 = 30 s to 2 x 30 = 60 s. Setting the time-out period retransmits the sent data and tries to connect to the server again until the connection is established.
3. Click OK to save your settings.
