.Nm

is a program to hold private keys used for RSA authentication.

is a program to hold private keys used for public key authentication

(RSA, DSA).

The idea is that

.Nm

is started in the beginning of an X-session or a login session, and

all other windows or programs are started as clients to the ssh-agent

program.

Through use of environment variables the agent can be located

and automatically used for RSA authentication when logging in to other

and automatically used for authentication when logging in to other

machines using

.Xr ssh 1 .

but is normally added to the agent using

.Xr ssh-add 1

at login time.

.It Pa /tmp/ssh-XXXX/agent.<pid> ,

.It Pa $HOME/.ssh/id_dsa

Contains the DSA authentication identity of the user.

.Pq Pa /tmp/ssh-XXXXXXXX/agent.<pid> ,

Unix-domain sockets used to contain the connection to the

authentication agent.

These sockets should only be readable by the owner.

The sockets should get automatically removed when the agent exits.
