Chicken of the VNC and conneting to multiple computers on a single LAN

I've successfully got Chicken of the VNC operating so that I can reach my iMac (running Leopard) from outside my LAN using my iBooks (running Tiger). And I can also connect to all computers inside my LAN by using Bonjour in chicken of the VNC.
What I cannot figure out is how to setup Chicken of the VNC and port forwarding to access my other three computers from outside of my LAN.
I suppose it is simply configuring the port forwarding correctly and apparently I'm not doing that.
I've got each Mac configured with a fixed IP as follows...
iMac is at 192.168.0.100
iBook is at 192.168.0.102
iBook2 is at 192.168.0.103
Acer is at 192.168.0.120
Right now the port forwarding on my Linksys WRT54G looks like this...
VNC1 5500 to 5500 Both 192.168.0.100 enable
VNC2 5800 to 5800 Both 192.168.0.100 enable
VNC3 5900 to 5900 Both 192.168.0.100 enable
VNC-iBook 5502 to 5502 Both 192.168.0.102 enable
VNC-iBook2 5503 to 5503 Both 192.168.0.103 enable
VNC-Acer 5504 to 5504 Both 192.168.0.120 enable
Enabling Bonjour in Chicken of the VNC lets me connect to all computers on my LAN. And I can connect to my iMac outside of my LAN using the WAN-IP:5900
But I cannot connect to any of the others except the iMac (at internal IP address 192.168.0.100 or outside IP of xx.xx.xxx.xx:5900) outside of my LAN.
Any quick tips?

If you have all of your Macs inside the LAN operating okay with remote access by CotVNC, then 3/4 of the battle is done. But first thing I would do is tunnel your VNC through an encrypted ssh tunnel, unless you don't mind the possibility of a sniffer outside your home network being able to intercept every one of your vnc packets in plain text and monitor your every vnc move.
The easy way to do it would be to connect via ssh to one of the computers inside the LAN with a bunch of ports tunneled through the encrypted ssh connection. I've got several posts that talk about tunneling vnc through ssh. Do a search on posts by me (j.v.) since last year with search terms "vnc ssh 5901". Port forward port 22 through your home router to, for example, your imac, and turn on remote login (ssh login) on your imac. You do not need 5900 port forwarded through the router, only port 22.
To access multiple computers, modify your ssh login command, that you type in Terminal on the computer outside your LAN, to add additional "-L" port forward switches, for example, "ssh -L 15900:127.0.0.1:5900 -L 15901:192.168.0.102:5900 -L 15902:192.168.0.103:5900 -L 15903:192.168.0.120:5900 [email protected] Then in CotVNC, you connect to 127.0.0.1:15900, 127.0.0.1:15901, 127.0.0.1:15902, or 127.0.0.1:15903, in order to connect to imac, ibook, ibook2, or acer. All the VNC traffic is encrypted and tunneled inside the ssh connection. All traffic to all computers is delivered to the imac's localhost interface, and depending on which port you specified in CotVNC, it goes to the computer specified in the "-L" switches for that port.

Help with Chicken of the VNC and Airport

I had my airport working with Chicken of the VNC perfectly and lost the settigns. Now I cannot get it to work again. What do I do a bridge or port forwarding? And how?
There is so much contradictory information that I have just spent the whole night not doing anything of use. Any precise help would be greatly appreciated.
Thanks in advance!

The basic steps to configure for VNC are as follows:
o Configure the machine you want to control (VNC Server) to allow VNC access. If the VNC Server is behind a router, then this would entail at least three things: 1) Configure the OS X Firewall to allow VNC access, 2) Configure the router to map port 5900 to the VNC Server, and 3) Know the WAN IP address of your router. (Note: One way to get the WAN IP is to go to the web site http://whatismyip.com and make a note of the ip address.)
o Connect to your VNC Server from a VNC Client from the Internet.
And I tried to do port forwarding but it doesn't seem to work.
Let's double-check your port mapping settings.
1. Reserve a DHCP-provided IP address for the VNC Server.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the VNC Server>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Service: <you can ignore this setting>
o Public UDP Port(s): 5900
o Public TCP Port(s): 5900
o Private IP Address: <enter the IP address of the VNC Server from the above step>
o Private UDP Port(s): 5900
o Private TCP Port(s): 5900
o Click "Continue"

Cannot remotely access mac mini via Chicken of the VNC post recent updates

Hi, updated my remote mac mini A running OS X 10.4 with QuickTime 7.5 for Tiger and AirPort Utility 5.3.2 Tiger yesterday. I can connect from my mac mini B via ssh into the mac mini A, but for some reason Chicken of the VNC will not work (it was working prior to the updates). I get the following message "channel 3: open failed: connect failed: Connection refused" in the command window when I try to get access to the computer via Chicken of the VNC and Chicken of the VNC itself tells me that the connection is refused.
Any suggestions? How can I remove the AirPort Utility 5.3.2 Tiger which I assume is the culprit? Thanks
(mac mini A is miles away, the only access I have is via the command window)

Welcome to the forums, and thanks for the tip!

Remote desktop with Share My Desktop/Chicken of the VNC

I read on these boards of an easy and free way to access a remote Mac using Chicken of the VNC and Share My Desktop. I talked my out-of-state parents through downloading and installing SMD and I installed CotVNC; my parents start SMD and they give me their IP, port and password info. I plug everything into VNC on my end, and I can't connect. Nothing I'm doing seems to work but from everything I've read, it should connect. Am I missing something- is there a setting that has to be tweaked for this to work? We're both running 10.4.11.
Help!

Well, I don't think robojet and robojet's mother were networking experts. A couple of my posts, like this one, that I referenced for robojet are laid out in about as much of a "cookbook directions" format as I think is humanly possible. You don't need to understand it, just follow the directions.
You're still gonna have to have both ARD turned on and VNC turned on in your folks' Sys Prefs Sharing whether you, on your end, tunnel through secure shell or not. The difference is whether you want to expose those ports on your folks' machine to the internet at large or not. If they don't have a router/firewall built into their DSL modem, the ports for whatever services you have enabled will be exposed, whether you tunnel through ssh or not.
I haven't looked at the SMD product to see whether it enables ARD and VNC or not. Could be if it wasn't run from an admin account, it didn't do what it was supposed to do on your folks' end because of permissions issues.
If you insist on running your folks unsecured, make sure they know how to lock down their firewall in their router that they should buy and install (or in their DSL modem if it has that functionality built into it already) when you are done VNCing, or they may have unwanted "visitors" like ibexcom did. They probably wouldn't be too happy with you if personal identity and/or financial information were stolen or their ISP accused them of staging DDOS attacks or of spamming, all because an unauthorized "visitor" gained access to their computer via an unprotected VNC link with weak VNC password.
Since you plan, at least initially, to get this up and running unprotected directly over the VNC ports, launch /Applications/Utilities/Network Utility and go to the port scan panel and scan their ISP-given IP address from port 5900 to 5903 and see if any of them are open. If the ports are not showing up as open, then you won't be able to connect. They can determine their ISP-given IP address here.
IF it were convenient for you to go to their place with a laptop and affiliate wirelessly onto their home network (like, with the $50 router that you buy them ), that would be a good start for doing baby steps to overcome the entry-level connection problems. Then make it work through ssh from there, then try it secure from your place.
Good luck!

Multiple Users in Chicken of the VNC

Can control only one user in Chicken of the VNC. When I sign into my wife's account I can't control the screen. I am using a iBook G4 1.33 GHz to control my G4 450 GHz tower running 10.3.9. I have OSXvnc 1.61 installed. I just upgraded to COTVNC 2.0b3 because 2.0b2 just stopped working. I have my wife's account with full privileges in sharing under the system prefs. Any help is appreciated

Is there a way to have a Chicken of the vnc type GUI over internet in ARD3?

Hello, to whoever reads this question, thanks in advance if you can help.
My need is this. I regularly use Chicken of the VNC for multiple administration over the internet, but what I like is the possibility to have same IP but Multiple clients with fixed IP (local) behind Firewall, i.e. x.x.x.x:5910 x.x.x.x:5920, x.x.x.x:5930, etc. and i can connect at the same time to the different machines to admin them.
Question: Is there any possibility to have the multiple connections with ARD 3 or even ARD 2 over the internet with same IP?
At one point ARD 3 did work for me like that for about an hour and then it stopped, blocking out 2 of 3 machines in the same IP. I mean, it acutally let me have 2 windows open on the same IP with different ports over internet and was flabbergasted, but then it stopped! when I quitted and restarted, I could do it no more…
I really like ARD, but if I got to manually change the port everytime I log in… yikes…!! I admin 20 machines in 10 different locations, so everytime i gotta log in to machine 'a' then change ports to machine 'b' for 10 locations everyday… well I hope you get the idea.
BTW i tried looking all over the forum, but could not find this info specifically.
PS thank you for your time

I, too, was a bit bummed out by the lack of this feature. I wondered if ARD 3 had some sort of mode Apple themselves used "silently".
There IS a way to make it work, however -- via VPN. I discovered that once I used VPN into my company's intranet, ARD 3's scanner could see EVERY Mac in the company.
Setting up a VPN nowadays is pretty simple -- many routers handle the support for you. OS X's Internet Connect feature makes it trivial to connect to the VPN, once it is properly set up from the inside of the company.

Chicken of the VNC connection help needed

Hello! I am not sure this is the right forum to post but it didn't seem to fit anywhere else. I have Airport Extreme v. 5.6 and am trying to connect to Chicken of the VNC. No luck. I selected the ARD settings in my system preferences, opened the firewall (which I don't like to do, wish there was a more secure way to control a client computer) and set up my connection on port 5900 in the airport admin utility. I have noticed that the IP my widget gives me is different than the one the base station reads. Help is appreciated Thanks

Hi Taryn,
Thanks for your quick and helpful reply. It is a bit
advanced for me at this point to comprehend, so if
you could simplify a bit for the remote connection
newbie that would be great, thanks so much :o)
That was the relatively simplistic explanation!
In order to remotely connect, the VNC client (you) needs to know the IP address of the VNC server (the remote computer you wish to connect to).
Every computer connected to the internet has an IP address, such as 200.100.54.14.
Some people have a fixed IP address, most though will be assigned an IP address by their ISP and this will generally change as and when they connect at different times.
However some people like to connect their networks to the internet which means that the network needs to share the single IP address connected to the internet.
This is usually done by a router, the router connects to the internet and this router has the external IP address. The router then using NAT to share the single IP address with multiple computers on the internal network (a subnet or LAN (local area network)).
What this means is that a computer on the LAN will have an internal IP address, this maybe fixed.
So when you send a remote connection request to the remote network, the router needs to know which computer on the LAN you are trying to connect to. You need to map the traffic coming in to the router to the specific machines you are trying to connect to.
This means that the remote router needs to be configured before you can remotely connect to a computer on the remote LAN.
I did just find out that I have been attempting to
connect with a laptop that has an every changing IP
(according to the client),
You (well he) could use a service such as Dynamic DNS to solve this issue.
http://www.dyndns.com/services/dns/dyndns/
but he is going to see
about transferring his work to his home computer that
has a fixed IP address. Does that sound more doable?
Depends on whether he has a router (see above)
Finally, do you think the pay services like ARD or
Timbuktu are perhaps safer? We like COTVNC because it
is free but I am very worried about the
confidentiality of my data.
COTVNC is according to the documentation secure.
Have a look at this guide as well.

Chicken of the VNC connects to my PC running RealVNC, Screen Sharing can't?

Hi,
One of the big features I was looking forward in to Leopard was being able to connect to VNC servers using the OS instead of a dedicated app, but when I try to use Screen Sharing to connect to my PC which is running a VNC server, I get the error:
"Connection Failed .... Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer you're attempting to connect to. Also make sure your network connection is working properly."
This also happens if I try to make the connection via directly launching Screen Sharing or from the side panel of a Finder window or by doing command-K.
The weird thing is that Chicken of the VNC connects to the server without a hitch. Anyone know what might be wrong here? The PC is running RealVNC Personal Edition and has Bonjour for Windows installed. The Mac and the PC are on the same subnet.
Thanks in advance for any assistance!

Finder probably isn't auto-detecting the VNC server because it likely isn't being advertised via Bonjour. I don't think Bonjour for Windows does much aside from give a Windows box the ability to listen for Bonjour printers and see Bonjour HTTP bookmarks. I'm unaware of it performing any sort of advertising of the services on a Windows box.
For Finder to do the auto biz, you will likely need some other sort of Bonjour advertiser, like Rendezvous Proxy or a mdns DNS server sending out an appropriate rfb.tcp service advertisement.

Pop up box in yahoo mail won't close, asks "do you use the yahoo! toolbar on multiple computers?" has option buttons but no response when clicking on anything, pop up box just sits there in the way

whenever I open my yahoo mail when using Firefox, a pop up box appears on the upper left side of the screen, it asks the question "do you use the yahoo! toolbar on multiple computers?" and gives click boxes for "Save to my yahoo ID" and "No thanks, just save to this computer". I get no response to clicking on either box, nor will the pop up close if I click on the "X" in the upper right corner of this pop up. It won't close out and it sits right over the top of the email messages in my inbox. All else seems to work fine, but can't get rid of this pop up box....very annoying.

Syncing the same iTunes library among multiple computers

I have two computers, a Windows 7 laptop and a new iMac. iTunes on both computers are signed into the same Apple ID. I currently have my iTunes library on my laptop, but I would like to also have the exact same library on my iMac. For instance, if I download a new podcast to my laptop, it should be placed on my iMac as well. When I delete the podcast, it should be deleted on the iMac too. When song metadata is updated on my laptop (play count, lyrics, etc), I want it updated on the iMac automatically.
I have not had much experience with Home Sharing, but would that do all of this automatically? I know I could manually transfer songs from one computer to the other using Home Sharing, but what about updated metadata or deleting files?
iCloud has made this situation more interesting. I know iTunes in the Cloud and iTunes Match will keep music files in sync among various devices (including metadata?), but what about podcasts or movies or files not purchased via iTunes? I know there are plenty of details that are yet to be released concerning iCloud, but do you think it will solve this problem entirely, or will manual labor be required to obtain the exact same library among multiple computers?
I have considered only using my iMac to maintain my library, since it is always on and I could use Home Sharing to listen to music on my laptop since they are on the same Wifi network. However, I feel it would be best to keep the same library on two computers for when I take my laptop on vacation away from my home network.
What would you suggest for this situation?
Thanks!

sorry about the slight irrelevence of this post on this thread....i saw this much older post you had in my explorations and it is almost to a "T" my issue currently and i was wondering if you ever came to a conclusion or had any tips or resolution paths i could explore. your original message:
     I have 2 computers I'd like to set up Home Sharing on. One is Windows XP and the other is Windows 7.
     I set it all up but then the libraries never show up. Nothing happens.
     The computers are on the same network and I can successfully share files and a printer. Both computers are      authorized using the same account. Both are signed into that account.
     I don't know why it's not working. Can you please help?
          Thanks!!
is EXACTLY my problem with the only variable being that both of my computers run 7. furthermore, you went on to say you were experiencing issues with the "remote" app. that was the initial objective for me in my system that got me here with a deeper problem with home share. i want to home share my itunes library and control it from my iPod touch 4g. is that such an unreasonable request?!?!? lol. i'm incredibly frustrated and was hoping that since you had such specifically similar circumstances....have you found a solution? PLEASE HELP!!! thank you so much for your time.

Can i use this download and install on multiple computers?

Can i use this download and install on multiple computers?

I assume you're talking about the Lion installer? If so, yes, you're allowed to use it on any machines authorized with your Apple ID (which I believe means a maximum of five machines). This is, of course, meant for family use... I'm not sure about business use, but I'd suspect you need one copy per machine at a business. If you're in that situation, you may want to wait for the $69 Lion flash drive Apple will be releasing next month sometime, as that won't be tied to an Apple ID. But check with Apple to be sure on that.

With home sharing, can I sync music and apps on multiple computers at home?

Hi.
With home sharing, can I sync music and apps on multiple computers at home?
Basically, I want to sync my iphone and ipad on 2~3 computers at home without deleting contents in my iphone and ipad.
thanks.

I did some more checking as I still had my old computer online.
I booted and went into iTunes.
Under DEVICES, the TV was listed, along with MUSIC, PHOTOS, PLAYLISTS, much like an iPod/Touch.
When I went into PREFERENCES->TV DEVICES, the TV was listed and on the site, it stated SYNCING.
On the other computer, it listed STREAMING. I did do a RIGHT CLICK on the device and selected "STOP STREAMING" and it disappeard - must RE-PAIR with the unit I guess.
I'm afraid to perform the following, but if someone out there has the equipment, maybe they can check...
Make sure nothing else is managing the TV.
Pair with the unit so you have all sorts of options under the device and it shows 'syncing'.
Now, create a new account and perform the same thing or use another Mac. I believe it will limit you to STREAMING only.
My thoughts are that ONLY ONE computer can sync (just like other device). I have to disconnect the association with the old computer.
Even though I moved everything over with Migration Assistant, I didn't have any issues with managing the iPhones, but I'm wondering if there is a Computer UUID that the AppleTV is TIED to. Since I'm on a different computer UUID, and it's being managed by another one, I'm limited to STREAMING.
Only other choice is to RESET the unit - now, where did my manual go?
Thoughts?
