Modify the configuration file/etc/network/interfaces.

Add eth0, eth1 settings at the end of a file

Auto Eth0
Iface eth0 inet Static
address 192.168.0. 201
Gateway 192.168.0.1

Netmask 255.255.255.0

Network 192.168.0.0

Dns-nameservers 61.166.150.123
Auto ETH 1
Iface ETH 1 inet Static
address 192.168.0. 201

Netmask 255.255.255.0

Network 192.168.6.0
Dns-nameservers 61.166.150.123

Modify the DNS configuration file/etc/resolv.conf

NameServer 61.166.150.123

Shutting down the firewall

UFW dissble

Restart the NIC

/etc/init.d/networking restart

Installing OpenSSH

configuration file: /etc/ssh/sshd_config

You can now connect to Linux using SECURECRT and so on.

If you are still not connected to the network at this time, consider rebooting the system reboot

Note: Gateway can only be set one, wireless network card connected to the Internet, need to set the gateway, wired network card Connection Development Board cannot set the gateway
