Is there a option to provide the password in ssh command?

[Hanry Zhou]

I want to to ssh to a host and within the same command line, I want to also provide the password,thus, not waiting for the ssh comimg back the password prompt.

Is there such option?

You can get ssh to not ask for a password instead, will that do?

You need to generate a key and copy that to the machine you want passwordless logins to. After that, you are fine. Have a look at the "ssh-keygen" man page.

Absolutely not. That defeats the whole purpose of using ssh.

SSH can be set to authnticate in three ways.

1. host based (Use of /etc/shosts.equiv and .shost files)
2. PAssword based.
3. Exchane of private and public keys.
(Keys are generated and public keys are put in taget hosts-user's authorized_keys file. This does not requuire any interactive steps when loggin in.)
man ssh-keygen for that.

I know I can ssh to the remote withought entering password by transfering the public key over, but can't I supply the password in the ssh command line? like:
ssh -l user remote_host -optiont password?

[Mark Grant]

as soon as you do that, you have provided an unencrypted password that can be obtained by naughty people. Just by typing that command at your terminal you put yourself at risk (even before you press ENTER).

Therefore it doesn't make sense for "ssh" to allow it.

I hope that openssh would not allow what you want to do.

It violates the very principle that the software was created to handle. secure shell. Putting the password and transmitting on the commandline completely defeats that purpose.
