.SH NAME
dynagen \- command line interface to dynamips Cisco 7200 Emulator
.SH SYNOPSIS
.B dynagen
.RI [ options ]
\fIconfiguration file\fP
.br
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
.SH DESCRIPTION
\fBDynagen\fP is a text-based front end for \fIDynamips\fP, that uses the
\fIhypervisor\fP mode for communication with \fIDynamips\fP. \fBDynagen\fP 
simplifies building and working with virtual networks. \fBDynagen\fP uses a
simple and easy to understand configuration file for specifying virtual router
hardware configurations. Configuration file has a simple syntax for
interconnecting routers, bridges, frame-relay and ATM switches. No need to deal
with NetIO's. \fBDynagen\fP provides a management CLI for listing devices,
starting, stopping, reloading, suspending and resuming virtual routers.
.br
\fBDynagen\fP can work in a client server mode, with \fBdynagen\fP running on
your Workstation communicating to \fIdynamips\fP servers running ona back-end
server. \fBDynagen\fP can also control multiple \fIdynamips\fP servers
simultaneously for distributing large virtual networks across several machines.
.PP
Before running \fBdynagen\fP you need to start \fIdynamips\fP:

.SH OPTIONS
This program follow the usual GNU command line syntax, with long
options starting with two dashes (`-'). A summary of options is included below.
.TP
.B \-n, \-\-nosend
Do not send any command to dynamips.
.TP
.B \-d, \-\-debug
Show debugging information.
.TP
.B \-h, \-\-help
Show summary of options.
.TP
.B \-\-version
Show version.
.SH CONFIGURATION FILE OPTIONS
Empty lines or lines starting with a hash ('#') are ignored.
.br
Configuration file, in other documentation also called \fInetwork\fP file,
knows three sections: global section, server section which starts with [...]
and device section which start with [[...]]. Server section and device section
can have multiple occurrencies.

.br
.B Server Section:
[<ip-address|hostname>]
.br
.B Device Section:
[[7200|ROUTER|FRSW|ATMSW|ETHSW <name>]]
The 7200 section specifies defaults for all 7200 routers on this Dynamips
server. Everything in this section is optional, and defaults to whatever the default is in Dynamips
.br
.TP
.B Global Configuration variable
.B autostart <true/false> (Default: True)
.br
By default, all routers are automatically started when a lab is launched. The
autostart keyword overrides this behavior, and the lab must manually be started
(start /all).
.TP
.B Server Configuration variables
.B port <1-65535> (Default: 7200)
.br
Hypervision port to connect to.
.br
.B workingdir <path> (Default: None)
.br
Set the directory where \fIDynamips\fP will store all the device files for this
network. This is the fully qualified path relative to the system running
\fIdynamips\fP.
.br
.B console <1-65535> (Default: 2000)
.br
Base console port. New instances that do not specify a console port will
default to this + the instance number.
.br
.B udp <1-65535> (Default: 10000)
.br
Set the base UDP port for NIOs.
.br
.TP
.B Device Configuration variables
.TP
.B [[7200]]
The 7200 section specifies defaults for all 7200 routers on this Dynamips
server. Everything in this section is optional, and defaults to whatever the
default is in Dynamips.

.B image <path/file> (Default: None)
.br
Full path to 7200 IOS image file. This is the fully qualified path relative to the system running dynamips.
.br
.B ram <integer> (Default: None)
Amount of Virtual RAM to allocate to each router instance.
.br
.B rom <integer> (Default: None)
.br
Size of ROM.
.br
.B nvram <integer> (Default: None)
.br
Size of NVRAM.
.br
.B disk0 <integer> (Default: None)
.br
Set size of PCMCIA ATA disk0
.br
.B disk1 <integer> (Default: None)
.br
Set size of PCMCIA ATA disk1
.br
.B cnfg <path/file> (Default: None)
.br
Configuration file to import. This is the fully qualified path relative to the
system running dynamips.
.br
.B confreg <hex> (Default: 0x2102) 0x210X where X=0,1,2
.br
Set the configuration register
.br
.B idlepc <string> (Default: None)
.br
Set the Idle PC value.
Include a description here.
.br
.B exec_area <string> (Default: None)
.br
Set the exec area size.
.br
.B clock <integer> (Default: None)
.br
Clock divisor (should no longer been needed as of dynamips 0.2.5 RC1)
.br
.B npe <npe-100|150|175|200|225|300|400> (Default: None)
.br
NPE type.
.br
.B midplane <std|vxr> (Default: None)
.br
Midplane, either "std" or "vxr"
.br
.B mmap <binary> (Default: True)
.br
Set to false to use real memory rather than a disk file for router vitural
memory. Conserves RAM at the expense of performance.
.TP
.B [[ROUTER <name>]]
All options from the 7200 section are options here as well, including
"autostart". <name> must be unique in network file.
.br
.B model 7200 (Default: 7200)
.br
.B console <1-65535> (Default: None)
.br
Console port. Defaults to the server's base console port (specified in the server section) + instance number.
.br

make sane decisions based on the interface specifications.
