b) I am using putty on windows for the first time when I connect the putty to the Linux Server it asks for acceptance of the key.I know this key is common and dummy as this key is with every fedora core 3 cd.How can I generate my own key so that I know that I am connecting to the correct server.\
Just type 'yes' and it will not ask you again.
This is what I am trying to say ,it is a dummy key ,Saying yes to that does not mean that I am connecting to the correct server.I want to create ony key and when i use putty to login into my linux server i should be sure that I am logging into the correct server.
What do you mean by "dummy key"? The sshd initscript generates a key if there is not one present when it is run. This key will be different on each machine, unless you have done something like "ghosting" an install so that multiple machines are bit-for-bit identical.
I want to do X11 forwarding .Means the X11 is running on my Remote linux server when i login into Linux server through Putty i want to use X11 windows or mode rather than using console mode.
You'll need to install an X server then. If you don't want to pay for one, try Cygwin.
