Real VNC ..

A vulnerability exists in RealVNC that could allow remote access without authenticating.
Does anybody knows where that files is located.. need to disable but can't find it the security scan was wad performed to a brand new solaris 11.1

We don't provide the Real version but if the problem is also reproducible with the other forks, you can remove the following package or you can disable the only SMF service that we use to start "VNC".
The SMF service is : svc:/application/x11/xvnc-inetd:default
And the package is : x11/server/xvnc

Real VNC issues with Windows 7

I am a system technician using this software on behalf of the Indiana Toll Road and we have already purchased several hundred licenses of Real VNC as well as Windows XP and Windows 7 as we use this software frequently to remote into various lanes and workstations
located at several networked plazas over a 153 mile distance.
I am currently testing this software with a Windows 7 PC and I am experiencing some issues with connectivity that is associated with logging off and/or switching users on this machine as we use an auto-login feature that requires the user to hold the
shift key down during the log off interval to log in under a different user. I have noticed this as being a major issue for a lot of users with the Windows 7 platform from the RealVNC website and I understand that after logging off you are able to regain a
connection. However, when using the auto-login feature, I am not able to hold the shift key down for that session because my connection has been lost and consequently not able to login as an administrator or any other user other than the auto-login user through
this remote service. Currently, we have Windows XP deployed on all of our computers. We are looking to upgrade our network to Windows 7 using the Real VNC software as Windows XP will no longer be maintained under Microsoft service agreement in the coming months.
Is there a way this issue can be addressed from either your software side of this issue... Microsoft and/or Real VNC? Deploying different software for this purpose would be rather cumbersome and not cost effective. So hopefully an update patch from either
side would be even more appreciated. Any thoughts would be very appreciated.
Thanks

Microsoft and/or Real VNC? Hopefully an update patch from either side would be even more appreciated. Any thoughts would be very appreciated.
Thanks
Since it is extremely unlikely that Microsoft will issue a patch to fix a Real VNC problem (which would be a case of the tail wagging the dog . . .), you need to get in touch with the Real VNC people about a patch for Windows 7.

Hi, we are using mac mini's for our developement purpose. connecting the same through using Real VNC. Mac mini's are late 2009 and 2010. Now we have upgraded them to 10.8.5. after upgrading having display issues after launching the simulators

hi, we are using mac mini's for our developement purpose. connecting the same through using Real VNC. Mac mini's are late 2009 and 2010. Now we have upgraded them to 10.8.5. after upgrading having display issues after launching the simulators, we are unable to view the icons we need to move the simulator (into different places) to view the icons.
Also we are having Mac book pro's (Late 2009 & 2010) after upgrading them to 10.8.5. Unable to launch the mac, getting only white screen with apple icon.
Let me know is there any specific Hardware (Graphic Cards) we need to use for the same.
Please provide me the early solutions.
Regards,
Suresh.

Hi, try this first...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Apple Remote Desktop 3 and Real VNC

Just wanted to post an FYI, that recently I found out VNC (Real VNC) Server & Viewer were conflicting with ARD 3.2 in terms of screen sharing/control. All other connections were fine. (e.g. chat, message, package install, etc..) For me to regain a successful connection to my clients I had to uninstall VNC, reboot and "whalla" screen share/control was full functional again. I don't know if anyone had a work around for the two programs to work simultaneously, but I couldn't figure it out and just uninstalled VNC. Not sure if this would be the same case with Ultra VNC, but I think it is safe to say that if you are wanting to remote manage a group of Macs (PC's included) you should stick with just one program. Any thoughts out there?

The "normal" version:
Yep. All generic VNC software will conflict with ARD. This is a good note for most admins out there.
The "geek" version:
Tell RealVNC to use port 5901. Look at the "Connection Options" section of the documentation for your server-side os/version.
The "too much information?" version:
Actually, VNC servers and ARD do just fine side by side. (Aside from listening and bonjour advertising and that), both servers are actually inactive until they receive a connection request. The clincher is that any services ...from Apache to ARD reports to SMB to VNC... always need to be listening to different sockets on different ports. In the good old days, VNC servers could actually listen on several ports and would serve at different color depths and resolutions based on the port number of an incoming request. In fact even today, because ARD uses a mostly standards-compliant VNC implementation, it has to use a different port for reports and commands and such so it won't conflict with the inbuilt VNC server.
VNC is usually on port 5900 nowadays. ARD uses 5900 for its VNC without asking. ARD also uses (or has used) 3283, 5432, 5433, and 5988 for reports and other non-VNC communication. (See: Apple's [list of common ports|http://support.apple.com/kb/TS1629].) In my experience, ARD's VNC client can very reliably control standards-compliant VNC servers, though your mileage may vary.
-- To control a non-ARD VNC server via ARD, just do whatever you normally would in ARD. When controlling, it may warn you that the VNC server doesn't support keystroke encryption, etc. but should still work fine.
-- To connect ARD to a VNC service running on a different port, choose "Add by Address… ⌥⇧⌘N" and in the address field, type the domain name or IP address as you normally would, but append a full colon ":" and the port number. For example, jsmith.example.com:5901 would connect to the computer named jsmith but would look for the VNC service on port 5901.
-- To control a Mac which is running the OS's ARD-VNC server from a third-party VNC app, you must have 'plain' VNC access turned server-side (that is, on the Mac to be controlled: System Prefs > Sharing > Remote Management > Computer Settings > "VNC viewers…"). As long as you use a decent client, it should work reliably after that.
I routinely run the standard ARD "Remote Management" services on my servers for normal remote interaction, but then have a Vine Server set up on 5901 with vastly different settings to benefit low bandwidth connections from the internet, from my iPod's VNC client, or through bouncy ssh tunnels.
If you have any other experiences or questions, or especially if anyone wants try any of this and encounters problems, by all means post back.
Cheers, Joel

Has anyone tried REAL VNC client for Mac OSX? Is it worth the money?

Has anyone tried REAL VNC client for Mac OSX? Is it worth the money?

you should not be getting that many crashes and unlike others here i don't see any strong reason to go to 7.2 other than to get to 7.2.1. i very strongly suspect you have dodgy AU's (probably around 218 of them) and if you have a look at your crash log it should show you why you are crashing. if you see an AU in the crash log it is telling you it is causing headaches. my guess is that upgrading is not going to solve your problems.
just so you know, if everything is running as it should be logic will hardly ever crash. post up the crashed thread from your crash log next time it happens. also make sure that you have the proapp kit latest version.
i know its deeply frustrating when things are going pear shaped. everyone but everyone feels that the stupid thing should just work and gets the over-whelming feeling that apple is supposed to make products that just work, that we paid good money for that level reliability and if it's going to act like this we might just as well have stayed with cheaper PC's. reality is, once you start throwing thrid party's into the mix it is really hard to keep control of reliabillity. if you took logic back to zero 3rd party plugs and in built audio, it would take fanatical fundamentalist to crash the thing. (having said that - i reckon i could)

A stable, fast reliable VNC connection to Lion or Lion server

I hope this post help people with VNC setup from non Mac machines to a Mac running Lion or Lion Server 10.7.4.
Apple has changed quite a few things in Lion regrading VNC and screen sharing. As a consequence many VNC viewers are no longer compatible until the VNC software is upgraded to be Lion compatible. You will find many posts about this topic in this forum, eg
https://discussions.apple.com/thread/3289794?start=0&tstart=0
Often, the result is that the user can't proceed beyond the gray login screen (screen locks up etc).
This post describes how configure Real VNCs VNC server on Lion Server 10.7.4 to work in conjunction! with ARD, thus allowing you to keep screen sharing enabled and still use ARD from client if that is desired)
Download the VNC server at (Version 5! necessary)
http://www.realvnc.com/download/vnc/latest/
and install the VNC server on the host (the computer you want to login to via VNC)
Single User Host setup
==================
- Install the VNC server and follow the intsruction
(If you your Mac is configured for remote management, screen sharing, remote apple events the installation may complete with error stating to contact the manufacturer....ignore the error as it most likely caused by a port conflict because VNC server and ARD (or apple scrren sgaring both use port 5900 per default), the software was still completely and correctly installed.
- start VNC Server by opening Finder -> Applications -> Real VNC -> VNC Server (User Mode)
You will see a small VNC icon in the top tsak bar of the screen.
(if you open the "information Center" the issues tab will show a port 5900 conflict)
- open VNCserver Options and select the connections tab:
+Change the default port from 5900 to 5901 and serve Java viewer on Port from 5800 to 5801
+ Change Authetication to "Mac password"
+ Select Encryption "always on"
- Selct the expert tab
+scroll down to the bottom of the list and change "StopUserModeOnSwitchOut" to "no"
(this settings prevents the VNC server to be stopped automatically if you have Fast Switching User Mode enabled on the host.)
- select "Apply"
(now if you open the Information Center" again, the port conflict problem should be solved.
- select "open" from the VNC server menu:
If the configuration was succesful, thw window will show a check mark in a green box stating everything is ok.
- In addition you will find the address that the client user will need to connect to the VNC server on the host
it will say something like "VNC viewer user can connect using the address 192.168.x.y:1"
Note: If you start several VNC servers, each session will need a dedicated port (like 5902, 5903 etc)
Router/Firewall Settings:
===================
Depending on the router/firewall you use your ports may have been automatically configured for you (airPort extreme for example).
You need to open port 5901 and 5801 and forward these ports to the IP address of the host. If ARD was alredy working in your setup, you can copy the port coniguration for ports 5900, 3283 and 3306 that are used by ARD and implement the same rules for the new port used by VNC 5901.
Review the settings of your firewall/router.
VNC client
========
- download the VNC client for your OS from
http://www.realvnc.com/download/viewer/
and follow the install instructions.
- Start the VNC client on your client PC (Windows for example) and enter the address that the VNC server reported to you earlier (192.168.x.y:1)
- Encryption : "Let VNC Server choose"
- select "connect"
- enter your Mac username and password that was setup on your host
you are now connected via VNC to your host.
You can also configure the VNC server to allow other users to login to the same! VNC session using their user credentials (friends/family or serverAdmins that want to share access to the host)
To do this open the options dialog box on the VNC server host computer and select "configure" next to authentication.
- add the users that are supposed to get access to your VNC session using their own credentials. (make sure this is what you really want, otherwise read on in the multi user section of this post)
Multi User Host Setup
=================
If multiple users are supposed to access the host computer using their own credentials logging into their own! desktop, follow these instructions:
- first enable Fast User Switching on your host computer by going to
System preferences -> User/Groups -> Login Options and select the check box "show fast user switching menu as..."
- For each user on the host that should be reached via a VNC session start VNC server (user) as described before and assign a new port number to the new user like 5902 etc.
- repeat the configuration outlined above for each user (eg. "StopUserModeOnSwitchOut" to "no")
(note initilally when you start the VNC server for the first time again, you will get notified that a port conflict exists again....this disappears as soon as the new port is configured)
now another user can login via VNC into his own desktop using the server address : "191.168..x.y.:2"
Final notes:
=========
I spent hours trying to get a variety of VNC viewers to work with the new screen sharing/VNC implementation in Lion and finally gave up. I called Apple Enterprise support and they confirmed that "a majority of the existing VNC products are not compatible with the new VNC implementation in Lion yet and that Apple recommends ARD". The discussion on what other non Mac users (Windows, Linux) should do did not go anywhere....
I have tested the above configuration with the free version VNC server 5 on the host and the free version VNC viewer 5 on a client. It worked flawlessly, fast, reproducable and very stable. You need to be aware that depending on the features you want (number of desktops, users etc) that you may have to purchase the personal or enterprise edition for the server.
The featurs are described here:
http://www.realvnc.com/products/vnc/
I personally installed the enterprise edition after I verified that the free editions worked stable and reliably as I needed them to work.
I hope you now have a stable VNC link into your Lion host from the platform of your choice !

I'm using the free VNC edition from RealVNC on Mt. Lion (10.8.5) and the basic information is in this article for Lion is confirmed for the VNC Server 5.0.6 (r113416) on Mt. Lion.
The main Options... window shows the Connections tab and I just changed my port to something other than 5900 and the port conflict went away.
The Free edition does not allow Mac password and encryption can't be enabled. (Ya gotta pay for that.)
Connected to it from my iPod Touch using Mocha VNC with no problems.

Keyboard unresponsive in gnome / VNC session

Greetings list -
I'm having a problem with a gnome session (Java Desktop) within VNC. When I start Real VNC server and connect to it with any vncviewer (Real, Tight, Ultra), everything comes up and looks fine. The mouse works, I can select things, drag windows, open menus, etc. However, when I try to type in an xterm or terminal session I get no response to the keyboard.
I have this in my .vnc/xstartup file:
xterm -geometry 80x43+10+10 -sb -sl 10240 -rv -ls -title "`hostname`" &
gnome-session &
If I replace "gnome-session" with "dtwm" I get a CDE desktop and everything works fine (the keyboard works). When I start gnome from the console I don't have these problems, so I think it is an interaction with VNC.
Has anyone else seen this and/or have a suggestion? Thanks!
- mikebo

I found that if you login in locally to the JDS, the user's home directory will be populated with the right files which will then allow a remote VNC connection with proper keyboard operation. I had the same problem since I started out trying a remote connection too.
Of course, if your Solaris 10 box is headless, it simply isn't possible to log in locally to JDS, so we have another thread going to try and find a patch for this issue.

VNC from Windows 7 -- Leopard

Hi,
Im using Ultra VNC from my WIndows 7 laptop to connect to my mac mini (leopard)connected to my Sony 40 LCD (single monitor setup). This is not working at the moment, my mouse gets connected but on the screen it says "Pleaed wait - initial screen loading".
I have also tried Real Vnc and it's the same.
Im running Vine server on the mac
On my old XP laptop this was never a problem. It got connected direct.
Any ideas //Anders

Maybe you should post this on a Windoze forum. As you said, it was working with XP.

Mac vnc server, XPpro client?

hello: I need a VNC app that will have server as OS X tiger, at a city some miles away (the "customer"). The client (offering our "service") will be here at home (small city 60 mi. away from the VNC server) on an XPsp2Pro, fast (t1 speed) dsl, ppoe, home routed c/s network.
What are the issues I need to consider? These are some of the things I have already encountered:
-what steps do I need to take to resolve IP addressing between VNC client & server?
-will our home routed network (which uses NAT) interfere?
-what VNC flavor will be the most trouble-free? The user is moderately tech-savvy, but her work is why the connection is there, she does not have the time to **** around with the VNC, that's my job to set it up right & let her get her (very billable) work done. I've already tried & failed to set up AjaxVNC (privacy complications on this new flavor). It looks like Chicken of the VNC is for a mac VNC client, don't we need a VNC server on the Mac? What about Ultra or Real VNC? What about Vine server on the Mac - how has it worked with other viewers?
Does OS X.4 need any VNC 3rd-party? If not, where might I find instructions to set it up on the customer's Mac? What VNC for that wXP will work best for that OSX?
Doesn't XPpro have builtin remote access? How might I set that up for accessing that mac (please steer me to website & I will read).
Thank you.

-what steps do I need to take to resolve IP addressing between VNC client & server?
What IP addressing issues are you encountering. This wouldn't normally be an issue.
-will our home routed network (which uses NAT) interfere?
Shouldn't do. They don't usually.
-what VNC flavor will be the most trouble-free?
You need a VNC client for the XP system. I can't help with rating them, sorry.
don't we need a VNC server on the Mac?
Does OS X.4 need any VNC 3rd-party?
Mac OS X Server already has what you need (part of the Apple Remote Desktop package.
Use System Preferences -> Sharing -> Remote Desktop to enable the screen sharing engine. You can 'configure' it to enable legacy VNC support.
Doesn't XPpro have builtin remote access?
No clue. If it does it's probably some proprietary Microsoft protocol and not something usable on your Mac server.

VNC on Oracle Linux 6.3

Hi,
I have just installed Oracle Linux 6.3 and I have noticed there is vncserver located in /usr/bin.
So I start the vncserver using
cd /usr/bin
./vncserver
I am prompted for a password, which I supply. An authority file /root/.Xauthority is created
A new desktop is created ( lab1.nms:1 )
A default startup script /root/.vnc/xstarup is created and the application is started
On my server I can now see the vncserver processes
root      2501     1 0 15:19 pts/1    00:00:00 ./Xvnc :1 -desktop lab1.nms:1 (root) -auth /root/.Xauthority -geometry 1024x768 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901 -fp catalogue:/etc/X11/fontpath.d –pn
However when I launch my VNC viewer ( Real VNC 5.0.3 for Windows ) on my remot windows client and provide the connection as lab1.nms:1 ( which is in my local hosts file on my remote client ) I simply get a timeout
There is no firewall between my client and server ( I am able to ssh, sftp, ping etc )
Any ideas of what is wrong ? Do I need to do some further config in VNC ?
Jim

Add /etc/hosts entries in the following format - IP    FQDN   hostname
Edit /etc/sysconfig/vncservers as follows:
     VNCSERVERS="1:<username>"
     VNCSERVERARGS[1]="-geometry 1280x1024"
# server vncserver start
# server iptables stop
# chkconfig iptables off
# chkconfig vncserver on
Login to your VNC server as xxx.xxx.xxx.xxx:1

Linux to windows - VNC?

Ok all, I need some advice. From work I currently have cygwin installed and can ssh to home and forward X calls - but thats not the problem.
From home, I am looking for a good way to VPN in and connect to my windows box. I know there's a bunch of VNC apps out there, and rdesktop, and FreeNX - does anyone have experience with any of these? I'm looking for recommendations

Just to provide some input on the VNC solution, I have been using the freely downloadable real vnc server on several w2k boxes:
http://www.realvnc.com/
and the vncviewer client app from the vnc package on archlinux with much success.
In fact I use this as a way to run a windoze desktop from within my arch workstation as a sort of uber-wine setup for applications that I just can't get on linux (e.g. 8-bit embedded microcontroller development tools).
I originally intended to use rdesktop, and this seems more integrated with windoze (read as m$'s effort to put the vnc crowd out of business). However it wasn't readily available on the w2k machines I needed to administer.
So I tried vnc and I haven't looked back since.
I use it primarily across my private network, but I do occasionally administer a few machines across the internet with it. In this case I have the remote user start the server just at times when I intend to log in, as I agree leaving it running all the time seems a security breach.
rdesktop may be better, but if it isn't just right for you I can report that the vnc solution as a very viable alternative.
Good Luck!

Extremely slow Remote Desktop via VNC

HI I am able to connect via Real VNC. However is it extremly slow. It is not a bandwith issue. I am connected locally and its slow slow. I am using REAL vnc on my pc.
What are you using for remote desktop and whats FAST!

I use Share My Desktop on the server side and Chicken of the VNC on the client side. I use this to connect 2 Macs that are 1200 miles apart. The speed isn't great but it is usable and certainly better than doing support merely by phone conversation.

Ultra VNC for Solaris

Is anyone running Ultra VNC on Solaris. We are currently running Real VNC rel. 3 on Solaris. Unfortunately, we have encountered some issues with fitting the application properly on the screen. Ultra VNC for Windows allows the ability to modify and change display to better fit screen. Your assistance is greatly appreciated. Thanks

did you solve your problem?

Remote access using ssh/vnc

Hi All!
Recently, I have managed to configure my Airport Base station to accept SSH using the port mapping/forwarding feature...
The main goal is to remotely access my mac in the office using SSH and VNC.
I was able to do this however remote Mac is using a high resolution which makes it slow to manage.[really slow].
I am currently using a Windows SSH tool called Putty.. and Real VNC to manage remote mac.
I tried to change the setting of Real VNC to a lower resolution but it would not work..accessing the remote mac will only work if my Windows VNC is set to use the
"Full" colour level.
Is this a windows issue? I haven't tried using a VNC for Mac though..
any other tool that is available out there aside from Apple Remote desktop?
Thanks, All!!!!
DP

so the system server VNC refers to the MAC os x VNC...
No, Vine Server's System Server is Vine Server starting up at boot time and is always running. Vine Server existed before Mac OS X included its own VNC server, so Vine Server's terminology is a bit confusing, but it wasn't when the started using it (it even sounds confusing when I just said it ).
the Vine server itself is the stand alone vnc.
Yes. The Vine Server is a totally separate VNC server implementation. It may be run interactively, or it may be configured to start at system boot time so it is always running (this is the system server mode of Vine Server).
so , OS X's VNC is set to only accept high res..
I do not know if it can ONLY do the resolution of the display, but anytime I've tried to use a VNC client configured for lower resolution, the Mac OS X VNC server has not behaved well. Rather than fight it, I just resort to Vine Server. It has been a rock solid VNC server.
so connecting to the Vine server should be at any port not the 5900as this is the mac os vnc default port.
If you MAKE ABSOLUTELY SURE that the Mac OS X VNC server is NOT running, you can use port 5900 for Vine Server, but I find it is safer to just give the Vine Server its own port, and commonly that is port 5901, but the Vine Server can be configured to use any port you desire.
Since I do not use a VNC client on Windows, I can not recommend any clients. However, I have heard of the following:
RealVNC
TightVNC
UltraVNC
I am sure there are others, but not being plugged into Windows culture, my depth of knowledge is very limited.

Setting up Apple Remote Desktop to control a PC using VNC Enterprise

I am using Remote Desktop 3 and have all my computers talking on my home network, this includes a Compaq PC using VNC and also 2 Power Mac G4's. All is well on my HOME network.
I would like to incorporate a computer (in a different state) over the internet.
It is a PC using VNC Enterprise Edition.
I was wondering if any fellow Mac freak could help a Newbie with a step by step process of adding the PC.
I wish to control certain programs for the other user but have no idea how to do so.
Just looking for a step-by-step as I've searched the Internet thorougly without sucess.
Thanks you in advance for your help
