Welcome to Virtual PC Simulator, Ver 0.5b2. VPCS is free software, distributed under the terms of the "BSD" licence. Source code and license can be found at vpcs.sf.net. For more information, please visit wiki.freecode.com.cn. 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, Windows or OS X(need more testing), 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 waits the dynamips to connect, and sends the packets to the ports from 30000 to 30008 which should be listened by the 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 commands of the VPCS. The line started with '#' or '!' will be discarded. usage: vpcs [options] [scriptfile] Option: -h print this help then exit -v print version information then exit -i num number of vpc instances to start (default is 9) -p port run as a daemon listening on the tcp 'port' -m num start byte of ether address, default from 0 -r file load and execute script file compatible with older versions, DEPRECATED. -e tap mode, using /dev/tapx (linux only) -u udp mode, default udp mode options: -s port local udp base port, default from 20000 -c port remote udp base port (dynamips udp port), default from 30000 -t ip remote host IP, default 127.0.0.1 tap mode options: -d device device name, works only when -i is set to 1 hypervisor mode option: -H port run as the hypervisor listening on the tcp 'port' If no 'scriptfile' specified, vpcs will read and execute the file named 'startup.vpc' if it exsits in the current directory. NOTE: 1. The cygwin1.dll used by VPCS maybe conflicted with other version. Please keep the latest cygwin1.dll in your system. 2. Set telnet LINEMODE to 'character at a time' while running as the daemon 'telnet> mode character' Website: http://wiki.freecode.com.cn or http://mirnshi.cublog.cn History: 0.5b2 fix: using getenv+access to the real path of VPCS. patch for Debian GNU/kFreeBSD from Daniel Lintott flush out the output buffer while running 'echo ...' increase the maxinum number of tcp sessions and decrease tcp keep alive time fix: arp table, the source ether address is not saved 0.5b1 support for a specified number of vpc instances (between 1 and 9) support for TAP device name (only with 1 VPC instance) support default filename (startup.vpc) for load & save commands. 0.5b0 support hypervisor mode 0.4b2 support DNS support 'dump' packets add 'rlogin' command to connect the remote host 0.4a support daemon mode 0.3 under BSD license 0.20a support IPv6 linklocal, stateless autoconfiguration new 'ping' with many optins, and implement the tcp state machine support load/save the VPCS configuration support save/load the command history automatically 0.16a Support IPv6 0.15a Add configure the host ip using dhcp 0.14g Fix the traceroute loop running bug 0.14f Fix the traceroute TTL bug 0.14e Fix the bug, parse 'echo' and 'traceroute' command line error. 0.14d Fix the bug which reply the arp request with broadcast address as the source MAC address. 0.14c Change the TTL to 64. 0.14b Fix the bug about the I/O queue. 0.14a Add arp function that shows the current arp table, 120 seconds expired. Add echo function that sends upd/tcp packet to the remote hosts. Now, you can test acl in your routers network. 0.13a Add ping localhost Fix a ping bug: get reply from any host ip. 0.12s Fix the tracert argument bug 0.10s Support udp mode 0.02s Fix a string copy bug 0.01s First version
