- Or in serial mode (RS232) by using a serial port (Aux1, Aux2...)
a) The TELNET Protocol
The telnet server is a standard module of the Unix/Linux TCP/IP stack. The AX3000 can
immediately open a client telnet session, without any additional software or alteration to the
Unix/Linux settings.
Main characteristics of a telnet session:
- Dynamic allocation of pseudo-terminals (ptty),
- System access is controlled by a 'login', which is generated by the telnetd daemon,
- The value of the TERM environment variable is negotiated after the login stage. (See
Chapter 8.1.8 for default TERM values.)
b) The TTY Protocol
The tty server is an Axel proprietary protocol. Additional software is required (see Chapter 8.4).
Main characteristics of a tty session:
- Pre-defined allocation of pseudo-terminals (ptty),
- UNIX access is controlled by a 'login', which is generated by the init daemon (controlled by
the
/etc/inittab
file).
The Unix/Linux host must run the AXEL tty server daemon (
axttyd
). The configuration file axttyd
must contain a list of AX3000 sessions and the pttys associated with each.
Each session is identified by the name of the AX3000 (from the
/etc/hosts
file) and a special
keyword (
sessx
where
x
is the session number). For example:
axel1
sess1
/dev/ptyp12
/dev/ttyp12
axel1
sess2
/dev/ptyp13
/dev/ttyp13
axel2
sess2
/dev/ptyp2
/dev/ttyp2
A thin client session controlled by the tty server acts as a serial terminal attached to a multi I/O
board. The
/etc/inittab
file must therefore be modified to launch the
getty
command for each
pseudo-terminal.
Example for SCO Unix: get a login on
/dev/ttyp12
:
p12:23:enable:/etc/getty -t60 /dev/ttyp2 m
This modification will take effect after invoking the following command:
# init q <CR>
For more information about the Axel tty server, refer to Chapter 8.4.
