Ping is a way of finding out whether a computer is working. See appendix C of the User Manual for further information on ping.

DNS Servers

Here, you configure DNS servers for the Telecommuting Module. The servers are used in the order they appear in this table, which means that the Telecommuting Module uses the top server to resolve DNS records until it doesn’t reply. Only then is server number two contacted.

No.

The DNS servers are used in the order they are presented in the table. To move a server to a certain row, enter the number on the row to which you want to move it. You need only renumber servers that you want to move; other servers are renumbered automatically. When you click on Save, the DNS servers are re-sorted.

Dynamic

If an interface will receive its IP address from a DHCP server, the Telecommuting Mod- ule can also get information about its DNS server from that server. In this case, select the corresponding IP address here and leave the other fields empty.

DNS Name Or IP Address

The DNS name/IP address of the DNS server which the Telecommuting Module should use. Note that to use DNS names here, there must exist a DNS server in the Telecommuting Module’s permanent configuration.

IP address

Shows the IP address of the DNS Name Or IP Address you entered in the previous field.

Delete Row

If you select this box, the row is deleted when you click on Create new rows, Save, or Look up all IP addresses again.
