See full text

A secured network system capable of easily constructing a groupware environment is offered. Host servers are placed within an intranet protected by a firewall. The host servers are connected with local servers located outside the intranet via a private network. At least some of files possessed by the host servers and the local servers are taken as common files whose contents are maintained in common with each other. Access to the common files in the host servers is allowed. The contents of the common files in the local servers can be gained from a cellular phone.
