How to use scp with the password ?
Hi,
I am using scp command to copy one file to remote machine as follows
Quote:
scp <localfile> root@10.0.2.5:/roo/
|
so it asking for the password,
my doubt is how to pass the password along with the command so i don't have to give password again.
I searched and find out about the keyfile set up but I do not need that idea .
I want to use the password.
So,kindly tell is it possible to use password if yes then how and if not then is there any other way to copy a file/directory in one command itself with out prompting for password.
kindly tell some suggestion ,it is needed for my work.
Thanks

passwords should always be entered manually. Your requirements fit *EXACTLY* with a preshared key. Why would you not want to do that?

Thanks for the reply,
I do not want the idea of key file because,in my project I may not always need to have that key file set in all the target machines adn also local machine for all the target file.
simply i have the password and a shell script to copy a file to all the machines.but it asking password so how to do this .
Thanks

In that case I would recommend to use expect. but keep in mind that hardcoding a password in a script is a very bad habit security wise.

I think you may do this via "expect".
#!/usr/bin/expect
spawn scp localfile root@192.168.1.13:/root/
expect "*password:*" {
send "mypassword\r"
}
This will automatically put password when password's prompt will be detected. Note in your case you have to connect your shell's script with this expect's script.

Can I just add further support to acid_kewpie & TobiSGD's advice: hard-coding a password is a really bad idea.

Hi
Keeping the password on shell script is very idea try to use ssh keygen instead of password.But Any way you can use these
sshpass -p 'password' scp user-name@scp-server-ip-addressath-of-the-file/file-name destination-location

You should look to adjust your requirements so that they do fit in line with preshared keys. they exist for a reason, and anything else is a hack.
