Configuring a PortMaster for Login Users
5-10 PortMaster Configuration Guide
Setting the Login Service
The login service specifies how login sessions are established. Table 5-1 describes the
four types of login services available.
Table 5-1 Types of Login Service
Login Service Function
portmaster PortMaster is the default login service and can be used to
access any host that has the PortMaster in.pmd daemon
installed. This type of login service is preferred because it
makes the PortMaster port operate like a serial port attached
to the host. This service is the most cost effective in terms of
host resources.
rlogin The remote login service rlogin uses the rlogin protocol to
establish a login session to the specified host. Generally,
rlogin is used on mixed UNIX networks where the
PortMaster login service is impractical to use.
telnet Telnet is supported on most TCP/IP hosts. This login service
should be selected when the PortMaster and rlogin protocols
are not available.
The default port number is 23.
netdata The netdata login service creates a virtual connection
between the PortMaster port and another serial port on
another PortMaster, or between the PortMaster port and a
host. This login service creates a clear channel TCP
connection. To connect to another PortMaster port using
netdata, you must configure that port as /dev/network
with the netdata device service and the same TCP port
number.
The default netdata port is 6000; however, you can specify
any TCP port number between 1 and 65535. This range
allows TCP/IP to be used with a hardwired connection using
an RS-232 cable. However, some serial communications
protocols, such as FAX, might have latency problems with
netdata.
