The mail service - provided by the server computer is conceived as a public - service so anyone with a modem attached to a computer would be - able to have access to it. However, due to hardware - limitations, only 100 users will be allowed to be registered - in the public mail service. Based on this information, the - lifetime of established connections will be of 15 minutes from - the established moment on. Once the connection has been - established, if the link is idle for 1 minute, the server - computer will close the established connection to free the - telephone line. This control can be implemented through the - and options - inside the pppd's configuration - file. - - - - Only registered user profiles will be able to establish connections - to the server computer. This control can be implemented using - the option in the - pppd's configuration file to define a - list of all telephone numbers that are allowed to establish - connection with the server computer, based on the list of - registered user profiles. By default, all telephone numbers - are denied from establishing access with the server computer, - except those ones explicitly set by - option. If the - option is not present in - pppd's configuration file, all - telephone numbers are allowed to establish connection with the - server computer, so be sure to include the - option in - pppd's configuration file if you - want to control who can/cannot establish connection with the - server computer. - - - -##### centos-pppd-config will overwrite this part!!!

The - centos-pppd-admin application would - be used to control the list of allowed telephone numbers - inside the pppd's configuration - file, based on the list of user profiles. The - centos-pppd-admin application - should be executed after any registration/deletion action - against the list of user profiles with root privilages in order to be - able of writing the settings on - pppd's configuration file. - - - - Redialing consecutive connections from the same telephone - number without any dealy between call retries must be avoided - from client computers. This would reduce the possibilities for - other client computers to establish connection with the server - computer. To prevent this issue from happening, it would be - necessary to provide more telephone lines than users - authorized to establish connection with the server computer. - Nevertheless, there is only one telephone line available for - the server computer to use. - - -
