78.2 SSH Agent
20210914 Entering the passphrase every time you want to do a remote copy or make a remote connection can be tiring. There is a simple mechanism provided to avoid this. by starting up a shell that runs an agent or by informing the current shell to run an agent (ssh-agent) and inform the agent of the passphrase using ssh-add.
An example of starting up a shell with an agent:
Or else simply start the agent within the current shell:
eval $(ssh-agent -s)
Then inform the agent of the passphrase just once:
$ ssh-add Need passphrase for .ssh/id_dsa Enter passphrase for .ssh/id_dsa Identity added: .ssh/id_dsa (.ssh/id_dsa)
The ssh-add command takes an optional argument to name the file containing the private key.
