smtpclient –s test –f [e-mail] –S IP_address [e-mail]

mail-body-message is the mail content. The last line of the body of the message should contain
ONLY the period ‘.’ character.
You will need to add your hostname to the file /etc/hosts.
SNMP
The UC-7112-LX Plus has built-in SNMP V1 (Simple Network Management Protocol) agent
software. It supports RFC1317 RS-232 like group and RFC 1213 MIB-II.
See Appendix B for a simple example that allows you to use an SNMP browser on the host site to
query the UC-7112-LX Plus, which is the SNMP agent. The UC-7112-LX Plus will respond.

OpenVPN
OpenVPN provides two types of tunnels for users to implement VPNS: Routed IP Tunnels and
Bridged Ethernet Tunnels. To begin with, check to make sure that the system has a virtual
device /dev/net/tun. If not, issue the following command:
# mknod /dev/net/tun c 10 200
An Ethernet bridge is used to connect different Ethernet networks together. The Ethernets are
bundled into one bigger, “logical” Ethernet. Each Ethernet corresponds to one physical interface
(or port) that is connected to the bridge.
On each OpenVPN machine, you should generate a working directory, such as /etc/openvpn,
where script files and key files reside. Once established, all operations will be performed in that
directory.
