Hello,

Are you looking to connect from Linux or Windows? Either way, check out RealVNC or TightVNC.

Kind regards,

Eric

Thank you very much for your reply . Please be informed that I need remote desktop access from my Linux server at the office to my Linux client remote at the far site (through modem dialup connections) . Please do me favor and propose for the available solutions in this regard (I know the PCAnyWhere can do the job if both sides are MS Windows clients)
Thank you in advance

You definitely should have a look at vnc then. vncserver and vncviewer come installed with the majority of distro's if I'm not mistaking.

Check on your systems with
Code:
which vncserver
which vncviewer
to see if they are installed (of course server needs to be installed on your server, and viewer on your desktop).

Kind regards,

Eric

Thank you very much for your reply . Please be informed that I installed TightVNC for Linux on my server & client . At now , I have "vncserver" on my server and "vncviewer" on my client . Please let me to ask you if you have a priori experience with this application to help me how to bring up PPP connections between my server and remote client on modem dialup connection to have remote desktop access ?
Thank you in advance

Because of low speed dialup modem connection & such above mentioned remote-programs are intensive networking throughput. I suggest you to remote your desktop by some command line shell client, like SSH-Secure Shell.

I also implemented some bridge networking program (or relay network). So you can make use of it. http://www.4shared.com/file/14408664...NE_online.html

========= HOW TO USE
1. On remote side. Just config in etc/switches.script
[server]
rhs1=tcp://localhost:22
lhs1=tcp://0.0.0.0:2222

2. On client side. Just config
[client]
rhs1=tcp://0.0.0.0:22
lhs1=tcp://<yourserverip>:2222


Because of this is cross relay. You can config it in any direction. For example, if your desktop is behind firewall, you can config like this: (do some port forwarding, if need)

[server]
rhs1=tcp://localhost:22
lhs1=tcp://<yourclientip>:2222
[client]
rhs1=tcp://0.0.0.0:22
lhs1=tcp://0.0.0.0:2222

I guess the reason is wrong owner or lack of execute permission. You should sudo chown & chmod this shell script.

Thank you very much for your reply . I solved the problem of "permission denied" with the help of your comment . Can you please do me favor and give me an example on how it can be used ?
Thank you in advance

Assume that your remote PC is seen directly from your client PC. I means that there is no firewall or you have full permission to control firewall (to do some port forwarding). Do some below step

1. Deploy one instance (what's I call network element - or node) in your remote PC with the following configuration (in switches.script)
[server]
rhs1=tcp://localhost:22
lhs1=tcp://0.0.0.0:2222
(It's also suppose that you installed SSH daemon in your remote PC, & do port forwarding on port 2222)
2. Deploy one node in your client PC with
[client]
rhs1=tcp://0.0.0.0:22
lhs1=tcp://<yourserverip>:2222
ping=left


With these configurations, your client node will try to connect to <serverip>:2222. If connected, it will start to listen connection from localhost:22. These node "bring" your remote PC to "local". Whenever your want to connect to your SSHD on your server, just using ssh client connect to localhost:22. Your network traffic will redirect to remote server.
