= **2 V-Box connect with third part server** =

140

141

V-Box have two mode.One is for V-Net,User need to use WECON server to store data.We call this V-NET platform.

142

143

(% class="mark" %)1.Europe server:eu.v-box.net

144

145

(% class="mark" %)2.Asean server:asean.v-box.net

146

147

Second is for OpenCloud mode.It means V-Box data will transfer to third part server and do not want to store data to WECON server.We call OpenCloud paltform

148

149

OpenCloud platform is used in configuring the script.Then V-Box can connect with third part server.

150

151

Both mode can support script to connect with third part server.the difference:

152

153

(% class="mark" %)1.If you want to store in WECON server ,please use V-NET.

154

155

(% class="mark" %)2.If your server requires SSL certificate to log in,please use OpenCloud.Because only OpenCloud platform can support to upload certificate
