Introduction

To configure CHARON-VAX networking, follow these 3 steps:

  1. Load network adapter (if required)

    If you are configuring a DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter, use the "load" command as shown below. CHARON-VAX 3100/96/98 and 4000/106/108 emulations automatically load SGEC (with the name "eza") and therefore no "load" command is required.

    Example:

    load DELQA/DEQNA NIC


  2. Load "packet_port" or "tap_port" 

    Load "packet_port" or "tap_port" to connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the host hardware network card (or to a virtual network interface).

    Example:

    load packet_port/chnetwrk NDIS interface = "eth0"

    classpagebreak

    Connect the loaded "packet_port" ("tap_port") to the loaded virtual network adapter

    Connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the "packet_port" ("tap_port") by setting the interface name.

    Example: 

    set NIC interface = NDIS

SGEC Ethernet Controller

The built-in SGEC controller emulator ("eza") has the following parameters that are specified with the "set" command:

...

Parameter

log

TypeText string
Value

If this parameter is set to some valid file name or a directory where the log files for each individual session will be stored CHARON logs Recv and Xmit packets at the emulated port layer.

If an existing directory is specified, CHARON automatically enables creation of individual log files, one for each session using the same scheme as used for the generation of the rotating log files. If the "log" parameter is omitted, CHARON does not create log.

In certain situations enabling this parameter may help to detect loss of packets.

Example:

set pp_1 log="pp_1.log"


set pp_1 log="/charon/logs"


Note

Only existing directory can be used as a value of the "log" parameter.

log_flush_period

Parameterlog_flush_period
TypeNumeric
Value
  • <period-in-seconds>

Defines a period of flushing log to disk.

Default period is 60 seconds (it means that every minute log file is flushed to disk)

Examples:

set pp_1 log_flush_period=30



Info

"tap_port" parameters are the same as "packet_port" ones
