In that case, you can hide the hostname of your machine. You must copy a key file, for example with ssh-copy-id uses ssh for data transfer. Normally the username and hostname of your Linux system appear in the terminal shell as email protected In some cases showing the hostname might be a security compromise. shellscript, so use bash shellscript # when shellscript in the current directoryīash path-to-shellscript/shellscript # from other directoriesĭo it (enter a passphrase when ssh-keygen asks) if you want higher security, because your private key will be protected (encrypted with the passphrase), but then you have to type the passphrase, when you run the script with scp. rw- 1 sudodus sudodus 349 dec 23 10:54 shellscriptĪnd you cannot run it directly with. rwxr-xr-x 1 sudodus sudodus 349 dec 23 10:54 shellscriptīut you had better cut it down to 600, no permission except for your own userID, and no execute permission at all $ chmod 600 shellscript rw-r-r- 1 sudodus sudodus 349 dec 23 10:54 shellscriptĪnd you may give your script files execute permissions for everybody, 755 $ chmod 755 shellscript The default permissions for a script file (when created somewhere in your home directory) is probably 644 $ ls -l shellscript Without key authentication and with clear-text passwords, it is very important to have strict permissions on the shellscript and it is a good idea also for security related shellscripts without a clear-text passphrase.

(press Enter to continue without a passphrase when ssh-keygen asks), because you don't want to type any password or passphrase when you run the script and arrive at the scp command line. You will probably be offered to protect the key with a passphrase. If you don't think it's important, try logging the login attempts you get for the next week. This is particularly important if the computer is visible on the internet. This way you need no password, and it is more secure too. Or add a new line if no PS1 already exists with: PS1. This is the executable used in the profile. In /etc/bashrc or /.bashrc change the PS1 environment variable to PS1.

This 'title' behavior can be overridden by using tabTitle. Login with key authentication to ssh is what you need. Some shells (like bash) may choose to ignore this initial value, while others (Command Prompt, PowerShell) may use this value over the lifetime of the application. Please do not hardcode a password into the shellscript, because it is easy for other people to read it.

SSH key authentication is convenient and secure
