Welcome to Virtual PC Simulator, Ver 0.13a.
The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or
ping/traceroute the other hosts/routers from the VPCS when you study the Cisco
routers in the dynamips. VPCS is not the traditional PC, it is just a program
running on the Linux or Windows, and only few network commands can be used in
it. But VPCS can give you a big hand when you study the Cisco devices in the
Dynamips. VPCS can replace the routers or VMware boxes which are used as PCs
in the dynamips network.
Now, VPCS can be run in udp or ether mode. In the udp mode, VPCS sends or
receives the packets via udp. In the ether mode, via /dev/tap, not support
on the Windows.
When VPCS started, it listens the ports from 20000 to 20008 and wait the
dynamips to connet, and send the packets to the ports from 30000 to 30008 which
should be listened by dynamips.
VPCS will look for the file named 'startup.vpc' in the current directory, and
execute the commands in it if you are not set the startup file from the command
line. All the commands in the startup file are the internal command of the VPCS.
The line started with '#' or '!' will be discarded.
vpcs [options]
-u udp mode, default
-e tap mode, using /dev/tapx
-s port local udp port, default from 20000
-c port remote udp port(dynamips udp ports), default from 30000
-r file run startup file
NOTE: To make compatible with dynamips, VPCS does NOT use the cygwin1.dll
released by cygwin.com. The two files conflicted.
