The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or ping/traceroute the other hosts/routers from the virtual PCs 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.
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 sends or receives the packets via udp. In the ether mode, via /dev/tap, not support
on the Windows.

If in the ether mode, please run it before the dynamips loads/starts the ios.
When VPCS started, it listens the ports from 20000 to 20008 and wait the dymamips to connet, and send the packets to the ports from 30000 to 30008 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 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.

Discussion
Just curious, I can get vpcs to load up in windows, but if I configure an interface for my local network and use my local router as the gateway, I cannot ping from Windows to the vpsc ip that I configured. Btw, my main connection is wireless.
Robert
I have dynamips and vpcs running on two different hosts on the same LAN. In my net file, I simply replaced “127.0.0.1” with the ip address of the host running vpcs in the NIO_udp line. I see the traffic going out and the traffic being received on the other host, but the vcps host does not respond, thus the vpcs cannot ping the dynamips router.
Is vpcs hard-coded to only work with the loopback adapter?
Hi… have you found any workaround.
I have a similar issue, but in my case VPCS bind the ports to 0.0.0.0 instead of 127.0.0.1
Please let me know if you can. Thanks.
yes, just for work easy.
Thanks mirnshi! Can this functionality be changed in the future and perhaps the source code released? I run dynamips in OS X and it would be nice to have a ported version of vpcs so I don't have to use multiple machines or play with static routes (to support multiple tap interfaces).
lovely! great! excellent!
lovely! great! excellent!
Amazing,
If you add nmap, telnet, ssh, traceroute and netcat functionality (maybe even tcpdump) then you would have absolutely coolect tool around for integrating with dynamips. That would allow us to do/test just about every single required feature.
hey…how do i add all these functionalities?? i would like nmap, telnet, ssh, traceroute, mtr….could you please guide me?
It's a layer3 tools to help NE to study router/switch, why add so many functions? Simple is the best.
To Mike J: I am looking for the OS X to compile the code.
With the new hot Dynamips GNS3 the RPort 30000-30008 is used in pemu, so I have a bat file to change in vpcs -c 40000 start, can you make this change in vpcs as default RPort to not conflict and make easier for noobs that want to use this great tool.
you can change these ports in the startup file. For example: 1 conf rport 40000
Hi,
Great program! But whats the complete syntax of the startup.vpc file? I got Bad command: “1 conf rport 40001”. after starting with that:
# The startup file of VPC # pc1 1 conf rport 40001 ip 192.168.10.2 192.168.10.1 24
I need different lport and rport for each PC. Hope u will help,thx Balazs
“tracert” is wrong!

Hi. It did not work on my PC. I am using Windows XP.
I run VPC and then when I run Dynamips, i got the following error:
6 [main] ? (4964) C:\Arquivos de programas\Dynamips\dynamips.exe: *** fata
l error - system shared memory version mismatch detected - 0x2D1E009C/0x75BE0096
.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start→Find/Search facility
and delete all but the most recent version. The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.
I note that my dynamips folder have your own cygwin and the VPC folder have one too.
What is the problem?
Can you help me?
I ran into the same issue and what helped me was deleting the cygwin DLL file in the VPC folder and copying the cygwin DLL from the dynamips folder into the VPC folder. I can now use VPC.
The cygwin.dll used by dynamips and vpcs is a special version, which can support IPv6, and will conflict with the same file released by cygwin.com. It recommends you to keep the latest cygwin.dll in your path because the different version will fight each other.
I note a problem when I replace the original cygwin.dll by vpc cygwin.dll, I can not make a telnet on my third router.
My lab has 3 routers and I do telnet to R1 and R2, but with R3 the window of Putty close automatically.
Any idea?

Nice tool , and I wonder if you can add port in the command “ping”,like this ping 10.0.0.1:8080 thanks

I have a problem when I want to connect the cable to the interface, it said unable to create UDP NIO, what's that suppose to mean ? thx b4
Some suggestions: 1) Add the -t flag to the ping command so that it can be used to generate traffic. 2) Add the ability to switch between multiple VPCs and generate ping traffic from each. 3) Add ability to change ping packet sizes, and use tcp or udp packets.
It's a great tool that I'll continue to use even without the suggestions.
Thanks
Hi I have a problem with using vpcs with GNS3. I cant run both simultaniouly. if I open VPCs first it will open but GNS3 will give a error when i start making topology saying “Can't connect to the hypervisor on port 7200”. if I open GNS3 first and make a topology it will work but then can't open vpcs application. it just open and disappears when i open it. kindly advice on this. (i'm using this with windows)
I got the same problem in Windows XP (both version 0.14g and 0.15a). How can I solve this?
I found the reason of this. Both Dynamips and VirtualPCs use cygwin1.dll, just copy file .dll from VirtualPCs overwrite file .dll in Dynamips (Remember backup original .dll)
Goodluck!!!!
thanks very much! really saved time! thanks thanks
hi, I also got this problem just now. I found that the WinPcap in my computer was uninstall in mistake and after I reinstall the software Gns3 work again. you may check if you got this problem either. Good luck…
Thanks!
I have a super simple setup with two switches (NSW) and a trunk, and I am trying to ping from VPC1 to VPC 2 each connected at the edges. ping response - host (0.0.0.0)not reachable. Is this not meant to work over L2 links? My VPCs have not gateway set. Thanks, J
ping response - host (0.0.0.0)not reachable
are you sure your setting is right?
please add telnet funcionality… (with selected ports) it's enough for me…
hello. this tool is awesom! thanks!!!
here is a tipp which i found in another forum, if you get a “206-unable to create UDP NIO” error on gns3:

Hi,
I have an strange issue. GNS3 its working properly, and VPCS runs fine without any error, cygwing1.dll also.
But the ports are binding to 0.0.0.0, not 127.0.0.1.
This is part of my netstat -an
Please let me know if someone has the same problem. Thanks, Francisco.
It's ok, nothing wrong.
I am having a problem integrating vpcs with gns3.First , I copied the vpcs cygwin1.dll to the dynamips directory under the GNS3 directory. Once , I did that dynamips was able to load. However , I followed the instructions in the gns3 tutorial for adding a computer symbol as a cloud type within the symbol manager. The computer symbol appears under the node types on the left pane under a category called decorative nodes. When I drag and drop the computer symbol it is of type decorative node and not the cloud type. I can't seem to define the computer symbol as a cloud type - I am selecting the cloud type but it doesnt save it as a cloud type. Can anyone help me on this.
Hello …
1. Keep the cygwin1.dll file on dynamips directory under GNS3 UNTOUCHED and copy this to the VPCS directory. 2. Follow the instructions in the gns3 tutorial for adding a computer symbol as a cloud type within the symbol manage and do a double click on the computer icon from the rigth column (COSTUMIZED NODES) to edit properties. 3. Save it with a diferent name (vPC for example).
I hope this can resolve youre problem.
I finally was able to define the computer symbol as a cloud type. Within the symbol manager I made sure to place several symbols in the right pane, with one being the computer. I was then able to select and highlight the computer symbol before naming it and saving it as a cloud type. Vpcs works great.

Hi,
I'm running VPCS v0.15a on a FC9 virtual machine with 256Mbps memory. I have it connected to a GNS3-emulated Cisco 3725 which acts as a switch, which in turn is connected to a Mikrotik router over VMNet 2. Connectivity is fine but I keep seeing “queue is full” messages, however, this doesn't affect performance. Is this because of running in VMWare?
Is the Mikrotik router a physical device? I never test the vpcs in these environment. Could you please post your topology?
Thanks for the reply. All devices are virtual machines running on VM Workstation. The host machine is Windows Vista. I run 4 virtual machines on it:
1. Fedora Core 9 with GNS3 and VPCS (256Mbps virtual machine) 2. Mikrotik RouterOS (128Mbps virtual machine) 3. Mikotik RouterOS (128Mbps virtual machine) 4. Fedora Core 9 with GNS3 and VPCS (256Mbps virtual machine)
The full topology is:
VPCS PC1–>GNS3 Cisco 3725 with NM-16ESW–>Mikrotik1–>Mikrotik 2–>GNS3 Cisco 3725 with NM-16ESW–>VPCS PC1
As I mentioned before I get end-to-end connectivity and the “queue is full” message does not appear until I start pinging and the only annoyance is that it interrupts the command line in VPCS. I also notice that if the virtual machine is idle and the Fedora Core 9 login prompt comes up then this too causes the message to appear. I can only assume that it is the memory of the virtual machine causing the issue but I have to be a bit cute to ensure that I don't slow down the whole PC when running all four virtual machines. The idlepc values have been calculated too and have got them to go as low as possible.
Thanks in advance for your help and a rather belated thanks for your program. Hopefully you've seen my run through on my blog (subnettingmadeeasy) of your program.
Kind regards,
Chris
I will check the code to find out where's wrong.
I got the same message “queue is full” on the VPCS console when pinging an configured IP. The problem was an rport bad configured on GNS3 cloud. Once i put it in the right way, worked well.
Regards.
Hello All,
I started getting the same message “queue is full” on the VPCS console too when I added VLANs to my C3725 switches. When I ping from a VPCS pc connected to any of these new VLANs ports the message appears. I hope this bug gets fixed soon cuz it's so annoying.
regards,
Nidal
it would be very usefull if vpc has the funcation of save the config file then we can save the ip address & cidr & gateway info next time when we use it again we can load the info
Just change the startup.vpc file if you use the same configurations over-and-over again although it would be nice to be able to specify our own configuration file on startup.
1. think you need to now to make the idelpc to work for you all time to all time low you need to eliminate the exec-timeout of the console to make the ios kick out of the prompt and make the cpu go high this are the command. and you cpu will be 0% all time ;)
r1(config)# line con 0 r1(config-line)# exec-timeout 0 0 r1(config-line)# logging synchronous

anyone know how I can “run” the vpcs.osx in Mac 10.4.x? I think I need to manually set up Terminal to do this, but I'm not sure.
like linux: 1. upload or unpack 2. chmod +x vpcs.osx 3. ./vpcs.osx
According VPCS I've configured Virtual PC to ping from one to another or to gateway address but it can't do. Would anyone please tell me what would be the problem?

Can you run gns3 and vcps on Windows Server 2003. When I load vcps after gns3 and vice versa — dynamips fails to start when I go to Preferences/Dynamips and run the test. I tried copying the cygwin1.dll file from vpcs to the directory for gns3 and vice versa but this does not solve the problem. I noticed that my server is listening on port 20008 the default local port for pc9 in vcps . But I can change this in the startup file with a “conf lport” command. Any help would be appreciated . I've got this working in XP , but I would like to run in Windows 2003 server.
Thanks Jim

you mean that you want to ping a host in ipv6 network, right? The host uses NDP(neighbor discover protocol) to discover the destination automatically in ipv6 network.
In my network topology I have added a Virtual PC to Switch and then Switch to Router, now I want to ping from Virtual PC (192.168.0.1) to gateway address (192.168.0.5) of Router. But I can not reach this. According to VPCS, I configured 3 Virtual PC like this:

Do you want to ping 192.168.0.1? PC1's ip address is 192.168.2.5. You should switch to PC3 before you set up PC3.
O sorry I wrongly write down here. Actually my VPCS is configured like this:
At this current scenerio when I am trying to ping gateway address (192.168.0.1) from PC1 (192.168.0.5), it shows the following message:
Would anyone please tell me what is the problem?
What does your .net file look like? You need to connect your VPC to the gateway, so you should have something like:
for VPC1-VPC3 connected to fa0/0 of R0-R2 respectively.
And I assume you have configured the routers, “no shut” the fa0/0 interfaces etc.
My .net file look like this:
there are 3 routers, 1st router conneted to 2nd and 2nd connected to 3rd router through serial link and there are also 3 LAN Switches and 3 VPCS. 1st LAN Switch is connected to 1st router, 2nd switch is connected to 2nd router and 3rd switch is connected to 3rd router.
And 1st VPCS is connected to 1st switch, 2nd VPCS is connected to 2nd switch and 3rd VPCS is connected to 3rd switch.
From this network topology I can say that every VPCS is connectd to router through LAN switch.
In my VPCS end I've configured NIO_udp:30000:127.0.0.1:20000 and also applied “no shutdown” command in fa0/0 interface of router. It is still not working. Is it mandotory to choose NIO Ethernet? I've three NIO Ethernet. Now what should I do to solve this problem?
Does the pc1 connect router? You said the vpcs connects the switch, 1st switch connects router.

Hello, is there an option to configure a IPv6 default gateway for a vpcs host? I can ping my directly connected intergace, but unable to ping anything beyond that. Per the config, for an IPv4 host: ip 172.16.1.2 172.16.1.1 24 (172.16.1.1 being the gateway) My directly connected host is a 3725 Cisco router and ND/RD is disabled. I wish to assign the addresses statically; So a simple question is does vpcs have an option to supply a IPv6 default gateway? Thanks
Disregard last post, I upgraded to 16c and added ip 2001:470:C19C:10::2 64 2001:470:C19C:10::1 and it works with no issues. Thanks for the app!
Well.. Maybe not; It appears that I enabled ND RA back on the cisco router for whatever reason, This is why it was working when I added the default gateway. I have suppressed the ND RA on the interface that is directly connected to the VPCS. It appears that the syntax ip 2001:470:C19C:10::2 64 2001:470:C19C:10::1 does not recognize 2001:470:C19C:10::1 as the default gateway. For now I will enable ND RA back on the Cisco Router; however, it would be nice to be able to traditionally add the default gateway to the vpcs config so that the host is not relying on Router Advertisements to locate a router to forward packets; Again, thanks for the app!
I am having the same issue as Samir above.
I just want to test VPCS and get it working so my topology is very simple.
3640 with NM-16 and NM-FE1. VPCS 1 and 2 are connected to ports 1 and 2o of the NM in the router. I see the ports as up/up. I have set the IPs for VPC1 and 2 in the same subnet, but cannot ping between them. Nor can I ping an IP on the router in this same subnet.
I have also tried this with a GNS switch between the router and the VPCs with the same result.
host (a.b.c.d) not reachable
GNS3, OSX, 10.5.7.
Any ideas would be greatly appreciated.
Thanks for all the hard work.
I connected the VPC1 to fa1/0 of a router (RTR1)
PC1 10.0.0.2/24 10.0.0.1 00:50:79:66:68:00 20000 30000
then the VPC2 is connected to another router (RTR3)
PC2 10.30.1.2/24 10.30.1.1 00:50:79:66:68:01 20001 30001
the problem is:
from RTR1:
I can ping the PC1 just fine
from RTR2
I cannot ping PC2, however when I do a “show arp” on the router it shows the address of the VPC2 as “incomplete” and eventually disappears from the ARP table
The workaround I discovered is i opened another VPC and it works
How can you have only 1 VPC running and connect the 2 VPCs to Different routers?

Hi,
Is it possible to send more than the default number of pings? A ping -t option would be great!
Hi,
What is the VPCS licence? I din't find it.
Thanks!
my net file is like this pc1 (20000 127.0.0.1 30000) connect to a switch switch connext to a router . ping router →pc is ok ping pc →router not ok why ????
When i add computer in GNS3 and specify the type as cloud . But in the node space it is showing under decorative device. i am not able to set the ports for computer
Amazing :)
host(x.x.x.x) not reachable and 206 - unable to create UDP NIO , I was stuck on these issues, my vpcs was not able to ping my router. please check my post below for solution.
http://crazy4tips.blogspot.com/2009/10/crazy-vpcs.html
1. If I type simply ip and hit enter, the program crashes (both windows and linux versions). 2. A “version” command would be nice, to check the version number 3. It would be nice if you could echo to routers as well as VPCS - at least for tcp - simply record the time for the 3-way handshake. At the moment, if i do an echo to say port 23 of the router, the SYN and SYN/ACK happen (but vpcs doesn't complete the final ACK) but I don't see any acknowledgement of this exchange - just the * * * output.
A great program - thanks.
Another problem with echo - the SYN/ACK from the VPC has a bad checksum, so if you are trying to echo a VPC through a firewall, the SYN gets through, but the SYN/ACK gets droped by the firewall because it has a back checksum See the Firewall Capture below:
PIX2(config)# cap cap1 in dmz real-time detail
Warning: using this option with a slow console connection may
result in an excessive amount of non-displayed packets due to performance limitations.Use ctrl-c to terminate real-time capture
I would like to suggest adding “ver” command in posible future new versions. Something like this: VPCS 1 >ver This is VPCS v0.16c
VPCS 1 >
can you tell me about use vpc in gns3? i don't know set IP for PC in gns3
I am using VPCS with Dynamips and have everything setup exactly as it should be. I will post the .net file the startup.vpc to confirm the same. Even now I am unable to ping the gateway from the PC and vice versa. Please help me identify the problem.
* Please note that there are no errors in terms of installation or .dll file setup ec, in case ther eis an error it has to be with the configs somewhere, please help me identify the same, I have almost given up now :(.

Can you confirm if this is something my end, as I've tried the usual firewall/AV fixes?
And also is the “current” version ok for x86 (32bit) Windows 7, as that's what I'm running at the moment.
Thanks for your help.

Hello,
I cannot run vpcs 0.15a. I use uBuntu 9.40 OS and got this message below even though I mask my permission to be executable!!!. Can you advise please.

Thanks mimshi - static routing configured incorrectly.
Hi Mimshi,
configuring the virtual pcs in a pc which is connected to office network(i m trying to configure this in office during free time) creates any problem??? I mean any routing issues because the pc is already connected to office network..
Hi,
Is there a way to run a continuous ping through VPCS? I'm testing spanning tree out right now and I want to setup a continuous ping from one vpc to another, then break the links and see the ping go down. IT doesn't respond to the ping -t command. I also tried ping ip address -t but no success either.

i just have a single problem with this.. . i use the 1st 3 PCs and whenever i close VPCS and re-open, i'll have to assign the ip address again and again…. . is there a solution for this?
