I would like to use "scp" to copy file from host A to host B , how to change the user of host A before file copy .

example :
Host A has a user peter & george
Host B has a user tom

at Host A run "scp file host B" , the copy process will run by peter , if I want the file copy is run by george , what can I do ? thx

Shalom

logged on as peter
scp -p filename tom@hostname:/tmp

Thats the basic syntax. So long as you know the passwords you can but username@ in front of the hostname.

You should use the user account registered on host B

scp file tom@hostB:/destination_directory

and then You will be asked to enter tom's password

Good luck!

Nash,

I've never used null password in my environment. I think it is not good idea
Rather than i recommend You to generate "ssh key" (ssh-keygen with -N '' arguments which tells it to generate keys with null passwords)

Hi,

look at the man page of ssh - you'll find all you need to setup passwordless file transfer.

In short:
- create keys for the 'from-user'
- put the public key of the 'from-user' into the authorized_keys file of the 'to-user'.
