Puttygen windows to linux

PSCPIs a command line application which is a free implementation of scp for win 32 platform . This tool is used for securely copying between computer systems. It uses the SSH (secure shell) protocol, which makes it impossible for other people on the network to snoop on your password or on the data you are transferring.

PSCP can run from the command line and has many options, which you can see via the –h option:

C:\>pscp -h PuTTY Secure Copy client Release 0.53b Usage: pscp [options] [user@]host:source target pscp [options] source [source...] [user@]host:target pscp [options] -ls [email protected]:filespec Options: -p preserve file attributes -q quiet, don’t show statistics -r copy directories recursively -v show verbose messages -load sessname Load settings from saved session -P port connect to specified port -l user connect with specified username -pw passw login with specified password -1 -2 force use of particular SSH protocol version -C enable compression -i key private key file for authentication -batch disable all interactive prompts -unsafe allow server-side wildcards (DANGEROUS)Here is a basic example of an user using PSCP to connect from Windows client to Linux server for transferring data to a specified path.

C:\>pscp -pw-r -p[email protected]:C:\>pscp -pw test -r -p "c:\New Folder\test.txt" [email protected]:/home/sandeep/In the above mentioned as we are providing the password its not a secure way of transferring file. Here comes the use of authenticating with RSA keys.

Preliminary Setup

Setting up public key authentication to access a particular remote host is a one-time procedure. We will require PuTTYgen for this process.

Steps for Authentication using RSA

Download PuTTYgen on your Windows client machine and Generate a public/private key pair on the same.

Click the Generate button. You will be prompted to move the mouse over the blank area to generate some randomness. Do so. Shortly thereafter, the program will generate the key and display the result
