#LOGIN WITH SSH ON MAC HOW TO#

I have a link to a Cisco TAC podcast on GetVPN and DMVPN in the references that does a great job of explaining how to use RSA key pairs and why you MUST export them. If you have exported the keys you just reload them on the new hardware and call it a day. If you don’t and the router fails you will have to touch EVERY tunnel once you replace the hardware.

It’s not so important in this case but if you have setup GetVPN on a router you absolutely want to export the keys used for the tunnels. This isn’t required but I wanted to point that out that you can make the keys exportable. While this isn’t absolutely necessary it’s the first thing I do on any production device.ģ750x(config)#ntp server 129.6.15.29 preferģ750x(config)#clock summer-time PDT recurring Configure an IP domain name, create the RSA private key and enable SSHģ750x(config)crypto key generate rsa modulus 2048 exportable I’m using a 3750X-48P-L running IOS Version 15.2(3)E1 for this example. You should also save the public and private keys to a file. Once the key is done you can select it and paste it into the switch. You will be asked to move the mouse around to generate some entropy. Enter a comment for your key pair and click Generate. Select SSH-2 RSA and enter 2048 for bits. I recommend storing your passphrase in a password manager so that you don’t for get it. Enter a description for your key and a passphrase. Once you have Puttygen double click to start it up.

It’s free but does require registration and an email address. If you prefer a GUI Hashtab is a nice tool that integrates into the right click menu. On Windows you can use the official MS tool FCIV to check the MD5 sums.

The MD5 check sums are at this link – checksums. Make sure that you download putty and puttygen from Recently there was some malware floating around using the name putty.exe. As a side note, Microsoft announced that it is going to build OpenSSH support into Powershell so you may be able to log into the next release of Windows server using SSH. There are resources in the reference section on how to create the keys using OpenSSH.

#LOGIN WITH SSH ON MAC MAC OSX#

OpenSSH ships with most *nix OS’s like Mac OSX and Ubuntu so you don’t need a separate program to generate the key pair. In this blog I am going to show how to configure a switch and create the public/private key pair using Puttygen for Windows. There are many resources showing how to configure SSH with RSA keys on the Internet and I have included several in the references section to give you more information.

#LOGIN WITH SSH ON MAC CRACKED#

While a password can eventually be cracked with a brute-force attack, SSH keys are nearly impossible to decipher by brute force alone.” Plus, it means you never have to type C!$c0 again!Ĭisco IOS now has support for using SSH with RSA keys. Digital Ocean, a Virtual Private Server (VPS) provider, has this advice on how you should log into their Droplets: “you should use public key authentication instead of passwords, if at all possible. This is because SSH keys provide a more secure way of logging in compared to using a password alone. Using an RSA Public/Private key pair instead of a password to authenticate an SSH session is popular on Linux/Unix boxes.
