These may be viewed by increasing the LogLevel to DEBUG or higher (e.g. Improvement: added support for SSH keys with ED25519 algorithm in SFTP sessions.The server may inform the client of errors that prevented public key authentication from succeeding after authentication completes using a different method. Socorro Electrical Engineering Division's Laboratory Experience (SEDLE) for UndergraduatesFree X server for Windows with tabbed SSH terminal, telnet, RDP, VNC and. If you are not at the top-level directory of the working. Specifying the location of the '.git' directory using this option (or GITDIR environment variable) turns off the repository discovery that tries to find a directory with '.git' subdirectory (which is how the repository and the top-level of the working tree are discovered), and tells Git that you are at the top level of the working tree.

It avoids having to enter the passphrase for each ssh or slogin or scp command that you use.As all NRAO Linux systems are configured to use gdm (the graphical display manager or "greeter") for logins, the ssh-agent process is automatically started for you. A Note on the SSH Secure Keys AgentThe ssh-agent program allows you to cache your private ssh key(s) so that you only get the passphrase challenge once per session. For RFI restricted areas, contact the Help Desk.
The best procedure for you is to generate a passphrase-enabled key ( i.e., one with a non-blank passphrase) on the laptop for each account. Once you have logged on, or have the terminal app running, type this:Users with tcsh or csh as their login shell should type eval `ssh-agent -c` instead.You probably have a local account or accounts on your laptop. It's there for you to use.For those who prefer not to use this app, or if you are using a text-only login such as a server or one of the Virtual Consoles of a Linux system.login, you may need to start ssh-agent manually.

There is no need to alter the public key the passphrase is used only to "unlock" the private one.Suppose you have just logged in to a brand new gdm session on your desktop or laptop, sometime after having generated the keys as shown above. RSA keys are now preferred for enhanced security.You can change the phrase on your private key later by using this command:It will prompt you for old phrase, and the new one (twice for verification). The private key is encrypted with your passphrase. This will generate an RSA key pair: id_rsa being the private key (and protected so only you can read it), and id_rsa.pub being the public key. See below for details on how to handle multiple sites.To generate or re-generate your ssh keys, you give the following commands in a terminal window:Make sure you enter a good, memorable passphrase. We hope all staff share this awareness.
When the second version of ssh came out years ago, it had the ability to use DSA keys as well as RSA keys. You do not need two separate files anymore. See the manual page on the ssh daemon ( man sshd) for details, and the manual page on ssh_config for the wildcard patterns you can use.Many of us may find we have both an authorized_keys file and another called authorized_keys2. Further, you have additional control in this file over the source of the connections you will allow you could for example prepend a key in the file with the string from=*.nrao.edu to restrict access to NRAO domain names. To permit your GB key to access your CV account, you want to append the GB public key to the CV authorized_keys file.The authorized_keys file can contain many records (each comprising of one rather long line of text) for many keys. For more security and a GUI, you can instead type:Note the two > greater-than signs, not one this appends instead of overwriting the target file!
So it is safe to kust have a single authorized_keys file in your ~/.ssh/ directory.
