please tell me if you meet the bug or the problem.
1. add arp command, show arp table, 120 seconds expired.
2. add echo command, send udp/tcp packets to the remote host
Virtual PC Simulator The VPCS can simulate up to 9 PCs. You can ping/traceroute them, orping/traceroute the other hosts/routers from the virtual PCs when youstudy the Cisco routers in the Dynamips. VPCS is not the traditionalPC, it is just a program running on the Linux or Windows, and only fewnetwork commands can be used in it. But VPCS can give you a big handwhen you study the Cisco devices in the Dynamips. VPCS can replace therouters or VMware boxes which are used as PCs in the Dynamips network.
Try VPCS, it can save your CPU/Memory. It is very small.
Now, VPCS can be run in udp or ether mode. In the udp mode, VPCS sendsor receives the packets via udp. In the ether mode, via /dev/tap, notsupport on the Windows.
InstallLatest version is 0.14a,
download and
unpack it.
vpcs.exe is windows program. vpcs is linux program, maybe you need
chmod +x vpcsUsage 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 VPCS 1 >?
show Print the net configuration of PCs.
d Switch to the PC[d], d is digit, range 1 to 9.
hist List the history command, use arrow keys to get
recently-executed commands.
ip address gateway [CIDR] Set the host's ip, gateway's ip and network mask.
In the ether mode, the ip of the tapx is the
maximum host ID of the subnet. Default CIDR is
24. 'ip 10.1.1.70 10.1.1.65 26', set the host ip
to 10.1.1.70, the gateway ip to 10.1.1.65, the
netmask to 255.255.255.192, the tapx ip to
10.1.1.126 (ether mode).
arp Show arp table.
ping address Ping the network host.
echo address port [udp|tcp] Echo the host port with protocol(udp/tcp).
tracert address [maxhops] Print the route packets take to network host.
default maxhops is 64.
conf [lport|rport] port Set local or remote port. 'conf lport' will close
the old port and open the new port. Only udp mode.
? Print help.
quit Close all the port(udp mode) or the tapx (ether
mode), then quit.

dynamips loads/starts the ios.
When VPCS started, it listens the ports from 20000 to 20008 and waitthe dymamips to connet, and send the packets to the ports from 30000 to30008 which should be listened by the Dynamips.
VPCS looks for the file named ‘startup.vpc’ in the current directory,and execute the commands in it if you are not set the startup file fromthe command line. All the commands in the startup file are the internalcommand of the VPCS. The line started with '#' or '!' will bediscarded.

Note
- To make compatible with dynamips, VPCS does NOT use the cygwin1.dll released by cygwin.com. The two files conflicted.
- You should run VPCS before startingthe dynamips while using ether mode. VPCS opens the tap interfaces. Andyou should know, VPCS will CLOSE the tap interfaces before quit.

2. fix a ping bug, can get echo reply from a non-exist host ip
1. fix the 'tracert' argument bug
1. replace a static array
