Title: Real VNC
Post by: del on October 20, 2003, 01:50:00 AM
Hi All,
Anyone using this to connect remotely? I have found the Redhat 7,3 rpm for it but was wondereing if anyone had succesfully installed it on any SME box,
Regards,
Del

VNC can't be used on SME due to lack of Xwindows!

If you want to control your SME server use the browser pages or ssh.

Hi

To connect to the server itself grab hold of PuTTy. Its the smallest tightest piece of code around for SSH connections.

A search in google for PuTTy will have the download page second on the list.

cheers
Tony

Hi,
Thanks for your input, I don't want to control the server, but to access a win2k machine behind it. I just thought that it would be a good idea to connect to the server and then use vnc to access other machines on the network. Sorry but I didn't make myself clear. Any how if it won't work then I will have to think of another way to do it, maybe VPN is the answer, as I read on hear that this is hit and miss I will have to do some searches first to find the ins and outs of using VPN, is there a howto? Once again thanks for your replies.
Regards,
Del

If you don't want to connect to the server, you don't need to install any RPMs there.  What you want to accomplish can be done through PuTTY or any other SSH client that supports tunneling.  There's a howto around somewhere (probably on contribs.org) that details using PuTTY to set up an SSH tunnel.

If you're just trying to connect to individual PC's behind the SME server then just forward the appropriate ports to each PC, eg:

forward port 5801 to 192.168.0.1
forward port 5802 to 192.168.0.2
forward port 5803 to 192.168.0.3
etc.

Then set the VNC server on each machine to listen to 'their' port. No need for VPN, no complex setup, indeed one can even use the Java-based server many VNC's have built in this way.

Also there are a number of good VNC distributions out there. RealVNC, while coming from some of the same folks that originally developed VNC is one of the weaker products. TightVNC is a good alternative and probably the leading VNC implementation out there. I'm a fan of Ultr@VNC myself as it offers chat (no need to share Notepad) and file transfer. All of the VNCs are interoperable btw.

Thanks for tip on Utlr VNC sounds great

Are these port forwarding commands just executed from the command line on the server? Also, are they static, or do you have to redo them after every reboot.
Thanks

Isn't it easier just to VPN to the server and then VNC/pcAnywhere/RAdmin/Your_favorite_remote_control_proggy_here to any workstation behind it?

Have used portforwarding and tightvnc to get remootecontroll to a windows machine behind a redhat router. Works very easy and strightforrward. Have not tried it, but the new sme 6.0 had a forwarding alternative at the admin panel. Shuold be only to run the vnc serer on the Windows machine, forward the ports via the sme and then perform the remoote control via vnc client software or web browser. Worked rather ok via the reddat router, but a little bit slowly. Guess it will be the same usin forwarding via the sme server.

I was about to say that,..... just VPN the server, and you can use Real VNC to control any machine on the other side.
It's better and it's secure...
good luck...!!!

"just VPN the server" How do you make the VPN work trough the firewall (the sme). I tried to set up a vpn connection to a sme 5.6 that was running behind a nat router. Could connect vpn from lan but could not connect vpn from the outside trough the nat router. Tried to set ut some forwarding but it did for some reason not work.  Anybody who knows exactly which port(s) to forward for pptp ??

The VNC alternative was very easy to set up but it is true that it givs a very poor security.

Easest way I have found is to use VNC.  I works well without creating security risks.
Install VNC on the client PC's Win9x, W2K, XP etc then when you need access get user to run the server.  With VNC running get the user to right click the icon in the system tray and select "Add client" give them your external IP to type in.  Then when they press enter you can take control of their PC works very well over ADSL and bearable over dialup.  

Running VNC this way will avoid the need to portforward on the client end.   Once you have finished get the client to close the VNC program on the taskbar for security.

You will need to forward ports 5800 & 5900 on your server throught to your PC and open any firewall for same.  Before they run the 'Add client' option you need to run the VNC 'Listen VNC Viewer".

Boris,

You do not need VNC to use RAdmin just portforward and you are in. I use RAdmin all the time for client servicing on several networks behind SME servers.

Will RAdmin allow me a VNC like control of a workstation behind the SME gateway?
Title: Re: Real VNC
Post by: JB on December 17, 2003, 05:46:27 PM
It looks like you have to pay for Radmin.  I use tightvnc on my W/S's and use the portforward panel and it works fine, without any issues.  I have tested this up to 3 w/s without any problems.  

YMMV,


JB

VNC,pcAnywhere, RAadmin, carbon copy etc. are all different remote control programs. you only need one of them. VNC is free, ethers are paid for but offer more options.

Arne,

Your nat router must support PPTP VPN pass through for it to allow inbound PPTP connections to your SME. Merely portfowarding will not work unless it has pass through support.

The alternative, as mentioned by other posts throughout the forums will be to get rid of the NAT router and use SME as the gateway / router.
