Strange SSH Behavior

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I have an Ubuntu server running 14.04.1 LTS.  I also have several  
Windows machines running Putty.  They all work exactly as expected.

I recently loaded a Dell E6400 laptop with Ubuntu desktop 14.04.1 LTS.  
I have all my machines using RSA certificates.  The odd thing that I  
have noticed is when I login to ssh server, it asks for my user name  
then asks for my pass-phrase, just as I expect, and then finishes the  
login.  The really strange part is that if I exit a running session,  
then do another 'ssh -p 1234 myhostname', it logs me in with no usercode  
or password prompt!  This is scary... The windows machines always prompt  
for usercode/password.

What have I done wrong (or not done at all) on the linux laptop?

Sorry for the long post ... help most appreciated,

RSA keys.

If you are using an RSA key, it's going to ask for the password you  
protected the key or do you need to authenticate at the remote system?

Ok, looks like it answeres the question above, you use the password to  
decrypt your RSA key, the unencrypted RSA key is valid as long as your  
session is valid.
