The user creates his/her RSA key pair by running ssh-keygen(1). This stores the private key in $HOME/.ssh/identity and the public key in $HOME/.ssh/identity.pub in the userâs home directory. The user should then copy the identity.pub to $HOME/.ssh/authorized_keys in his/her home directory on the remote machine (the authorized_keys file corresponds to the conventional $HOME/.rhosts file, and has one key per line, though the lines can be very long). After this, the user can log in without giving the password. RSA authentication is much more secure than rhosts authen- tication.<o:p></o:p> </div> <div> <o:p></o:p> </div> <div> <o:p></o:p> </div> <blockquote style='border:none;border-left:solid blue 1.5pt;padding:0in 0in 0in 4.0pt; margin-left:3.75pt;margin-top:5.0pt;margin-right:0in;margin-bottom:5.0pt'> -----Original Message----- From: Richard Santiago [mailto:rsantiago@rcm.upr.edu] Sent: Thursday, June 09, 2005 2:34 PM To: Petrucci, Joseph Subject: RE: [Nagios-users] Uptime on Linux Servers<o:p></o:p> Joe,<o:p></o:p> <o:p> </o:p> Thanks for your help man.<o:p></o:p> <o:p> </o:p> <div> Richard Santiago<o:p></o:p> OSI - Administración de Sistemas<o:p></o:p> UPR - Recinto de Ciencias Médicas<o:p></o:p> phone: 787.758.2525 x. 2934<o:p></o:p> e-mail: <a href="mailto:rsantiago@rcm.upr.edu">rsantiago@rcm.upr.edu</a><o:p></o:p> <o:p></o:p> </div> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabIndex=-1> </div> From: Petrucci, Joseph [mailto:Joseph.Petrucci@ddiworld.com] Sent: Thursday, June 09, 2005 2:31 PM To: Richard Santiago Subject: RE: [Nagios-users] Uptime on Linux Servers<o:p></o:p> </div> <o:p> </o:p> <div> IN ssh you can setup a trust so that the nagios ID only needs the key file and a pasword is not asked for.
