Setting Network Parameters

The New Sample:Network page lets you define all the major network parameters of the Container you are creating.

• In the Global Network section you can assign a search domain and a DNS server IP address to the Container sample. These IP addresses will be used by the Container based on this sample regardless of whether it is on a bridged network or depends on the host Node network interface.
  • Indicate one or more DNS servers that the Container based on this sample is supposed to use in the DNS Server IP Address field or leave it blank. Use the or icons to add/remove the DNS servers IP addresses accordingly. For Linux-based Containers, all the DNS servers are common for all the Container virtual adapters. Note that the static values in these fields might be overridden if the Container gets the DNS servers from the DHCP server when operating in the bridged network mode.
  • Define a list for hostname lookup in the Search domain field. Use the or icons to add/remove the lookup parameters for the Container. The search list is normally determined by the domain name(s); by default, it contains the local domain name(s) only. You can also add external domain names for a particular Container. A search query is performed by attempting to use each item in the list in turn until a match is found. Note that this process may be slow and may generate a lot of network traffic if the servers for the listed domains are not local, and that the query might time out if no server is available for one of the domains. Note also that the static values in these fields might be overridden if the Container gets the search domains from the DHCP server when operating in the bridged network mode.
• To set the Container based on this sample to be connected to the host Node NIC by the agency of the venet0 virtual adapter, select the check-box next to the Routed Network section. This adapter will be assigned an IP address taken from the IP pool .

  You can specify the following parameters for a routed network adapter:

  • Indicate one or more DNS servers that the Container based on this sample is supposed to use in the DNS Server IP Address field or leave it blank. Use the or icons to add/remove the DNS servers IP addresses accordingly. In Windows-based Containers, each virtual adapter can have its own DNS server.
  • Specify one or more WINS servers that the Container based on this sample is supposed to use in the WINS Server IP Address field or leave it blank. Use the or icons to add/remove the WINS servers IP addresses accordingly.
• Selecting the Bridged Network checkbox connects the Container based on this sample to the Virtuozzo bridged network through a virtual interface. Multiple virtual interfaces are possible per Container and can be added by clicking the Add New Interface link in this section. When a Container is provided with a virtual interface and is connected to a bridged network, its in- and outbound traffic is processed by the bridge of the Virtual Network to be selected in the Connect to field. In case no Virtual Networks has been created as yet, click Network on the Infrastructure Manager left menu, select the Virtual Networks subtab, and click the New Virtual Network link.

  You can specify the following parameters for a bridged network adapter:

  • The IP Address Allocation drop-down menu lets you choose whether the IP addresses for bridged interfaces will be leased from an IP addresses pool or assigned by a DHCP server (or servers).
  • Indicate one or more DNS servers that this Container is supposed to use in the DNS Server IP Address field or leave it blank. Use the or icons to add/remove the DNS servers IP addresses accordingly. Note that the static values in these fields might be overridden if the Container gets the DNS servers from the DHCP server when operating in the bridged network mode.
  • Specify one or more WINS servers that the Container based on this sample is supposed to use in the WINS Server IP Address field or leave it blank. Use the or icons to add/remove the WINS servers IP addresses accordingly.
  • Enter the default gateway IP address if the Container based on this sample is not supposed to use a DHCP server.
