I am using a TransPort WR21 for testing on Verizons network and need to look at the data usage to keep a record. I know how to look at it through the web version, but I would like to SSH to the outside IP and use a command to tell me the mobile data usage. I have also seen the ethstat command which gives the data of the eth0 port, but this data is not what I want. Any help would be greatly appreciated. Thanks.
