Is there a way to configure a password for a stored session in PuTTY?
I know there is the capability to specify an "auto-login username" (under Connection/Data), but is there a way to do the same with the password?
For some versions of PuTTY, it's as simple as one of:
putty.exe email@example.com -pw mypassword putty.exe somewhere.com -l mylogin -pw mypassword
If you want to connect using SSH, use this:
putty.exe -ssh firstname.lastname@example.org -pw mypasswordforsomewherecom
For those using Windows, you can simply create a shortcut and pass in these parameters.
PuTTY - server.com
"C:\Program Files\PuTTY\putty.exe" email@example.com -pw password
If your PuTTY does not support the
pw parameter, you will need a public key as explained in:
Creating and Copying Your Key-Pair in PuTTY SSH Client.
Opening PuTTY from WinSCP can be done from either the login window, or from the SFTP window, which I find extremely handy:
If you want to preserve saved options (such as pre-configured window sizes and tunnel proxy) and load a saved session to auto-login, use this approach: http://www.shanghaiwebhosting.com/web-hosting/putty-ssh-auto-login
putty.exe -load my_server -l your_user_name -pw your_password
Where 'my_server' is a saved session name.
PuTTY Connection Manager is a separate program that works with PuTTY. It can autologin and has an encrypted database holding the passwords.
I still prefer SSH keys though.
(Another downside is that it may no longer be supported by its original developer(s), and may only be available to download from third-party sources.)
Combining two different packages for a security solution can be dangerous. This is the PuTTY-only way to do it, only using software from the PuTTY site.
You should first use PuTTYgen to create a key pair, then install the private key in PuTTY, and copy the public key to the remote site. Here is how you do this.
Download PuTTYgen, and execute it to generate a SSH2-RSA key. I'd use at least 4098 bits. Click the Generate button, move the mouse around, until the key pair is generated.
Describe the account in the "Key Comment" field. Then save the private key in one file, and the public key in another file.
Your public key will look like this:
---- BEGIN SSH2 PUBLIC KEY ---- Comment: "rsa-key-20160822" AAAAB3NzaC1yc2EAAAABJQAAAgEA5Kp+G9z8eE0MpPZL9JZksstIa3L9JEND6ud1 1IiD6f1jw/7Lv7CvZcCdk/OVMT+DlTbryRoqfbNMLkjajqNTUGBAscTduUtPYuQt YEQgtbJd/hyHtTHK9X/wiKeQr7LjHZcEg3osYh+MzZFscldQM/a/Z26AKh81EC9X uIu98snjOBM0ysb14Uu7hMvti5Xd3kSW7ctL2j1ORuRgZX6LHihaezvsBFI5S/lZ 4v/yxymRKQnyV6OkMNMXESJpXh3cTMIIGtDJtbbYvh5Qs0f3O1fMiQYyz2MjGphd zBihq85a1SHx0LBk31342HsCiM4el//Zkicmjmy0qYGShmzh1kfZBKiBs+xN4tBE yjRNYhuMGP2zgpr9P/FO1buYdLah5ab3rubB5VbbRP9qmaP2cesJS/N91luc099g Z+CgeBVIiRr1EYTE8TqsSBdvmu3zCuQgDVcSAoubfxjM4sm3Lb6i4k4DJmF57J6T rcyrSIP9H/PDuBuYoOfSBKies6bJTHi9zW2/upHqNlqa2+PNY64hbq2uSQoKZl1S xwSCvpbsYj5bGPQUGs+6AHkm9DALrXD8TX/ivQ+IsWEV3wnXeA4I1xfnodfXdhwn ybcAlqNrE/wKb3/wGWdf3d8cu+mJrJiP1JitBbd4dzYM0bS42UVfexWwQSegDHaw Aby0MW0= ---- END SSH2 PUBLIC KEY ----
You have to edit this to a form that is suitable for your remote site. Let's assume it's a Linux machine using ssh.
Edit the file so it has three fields:
So it should look like this when done
ssh-rsa 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 rsa-key-20160822
Personally, I would copy the file over to the Linux machine, and then edit it, because editors like vim are much more tolerant of long lines. I'd use the 'J' command to join two lines, then search for spaces and delete the spaces between the lines. When I copied this file over to Windows, the system insisted on splitting the single long line into multiple lines with "\" between the lines. Yuck. To continue...
Log into the remote machine, and copy/edit, then append the public key into the ~/.ssh/authorized_keys file in the same format as the other keys. It should be a single line. There should be three fields on a single line. The first says "ssh-rsa". The second is the key which should end with the characters "=" the third field is optional, and will contain what you put in the Key Comment field.
If this is the first time you have created the ~/.ssh/authorized_keys file, make sure the directory and file are not group or world readable.
Once this is done, then you have to create a PuTTY session where the private key is used.
Then save this session (I'm assuming you also set up the account, IP address, etc.).
Once this is done, you just have to select the session, and you are logged in.
A more secure way is to store your private key in an encrypted file, using a passphrase. Then use Pageant to manage your passphrase. That way the private key is always encrypted, and you only have to type in a passphrase once in a while.
I prefer doing like this on a Windows machine. Save the PuTTY executable in a folder, say "mytools", and run this command from command prompt:
10 is the last octet of your IP address. That's it.
@ECHO OFF set PUTTY=E:\tools\putty.exe start %PUTTY% firstname.lastname@example.org. %1 -pw yourpassword
If the connection is authenticated by a public key and password, consider using Pageant.
You can add your private keys to Pageant with the associated password. Assuming you've got the correct username configured in PuTTY, you will authenticated transparently.
It doesn't store your passwords so you'll have to re-add your key next time you launch it. There is a command line option to launch and add keys in one go.
"C:\Program Files\PuTTY\Pageant.exe" key1.ppk key2.ppk key3.ppk
It will prompt for a password if required.
And the best of all, it's part of the PuTTY suite, so you've probably already got it on your machine.
