CAPI Services
102 KEN! – 5 KEN! for the Network Specialist
two IP addresses are registered as “Fixed DNS servers”.
This offers the advantage that the correct DNS server is
used, no matter which Internet provider is active.
• In rare cases it may be necessary or advisable to regis-
ter other IP addresses as “Fixed DNS servers”, for in-
stance when another DNS server is to be used in the lo-
cal network, or if the Internet provider is not able to
transmit the DNS servers in the context of IPCP.
IP Name Resolution on KEN! Clients
IP applications that fall back on HTTP, FTP, POP3 or SMTP
(browsers, E-mail applications) do not actually require any
name resolution at the KEN! Client since this operation is
performed by the KEN! proxy or E-mail server. However, some
Java applications, like those for “Chat” or special Internet
services, require IP name resolution at the KEN! Client.
For this reason the KEN! Client should register the IP address
of the KEN! Service PC (in the example network,
192.168.115.1) as the DNS server in the TCP/IP settings. This
is automatically the case when the KEN! Client receives an IP
configuration from the KEN! DHCP server.
CAPI Services
KEN! Client contains the ISDN applications interface CAPI
2.0. The KEN! Service PC and the KEN! Client communicate
via UDP/TCP.
The KEN! package includes the ISDN communications appli-
cation FRITZ! with licenses for all KEN! Users to use ISDN ser-
vices. The FRITZ!web module is excluded from the installa-
tion routine.
KEN! supports the assignment of multiple subscriber num-
bers (MSNs) for incoming and outgoing connections.
FRITZ!fax or other CAPI fax applications can send faxes to
KEN! Clients and receive faxes from them. For reception all
that is required is an unambiguous MSN assignment to the
KEN! Client.
