.Nd adds RSA or DSA identities for the authentication agent
|
|
.Sh SYNOPSIS
|
|
.Nm ssh-add
|
|
.Op Fl lLdD
|
|
.Op Ar
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
adds RSA or DSA identities to the authentication agent,
|
|
.Xr ssh-agent 1 .
|
|
When run without arguments, it adds the file
|
|
.Pa $HOME/.ssh/identity .
|
|
Alternative file names can be given on the command line.
|
|
If any file requires a passphrase,
|
|
.Nm
|
|
asks for the passphrase from the user.
|
|
The Passphrase it is read from the user's tty.
|
|
.Pp
|
|
The authentication agent must be running and must be an ancestor of
|
|
the current process for
|
|
.Nm
|
|
to work.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl l
|
|
Lists fingerprints of all identities currently represented by the agent.
|
|
.It Fl L
|
|
Lists public key parameters of all identities currently represented by the agent.
|
|
.It Fl d
|
|
Instead of adding the identity, removes the identity from the agent.
|
|
.It Fl D
|
|
Deletes all identities from the agent.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width Ds
|
|
.It Pa $HOME/.ssh/identity
|
|
Contains the RSA authentication identity of the user.
|
|
This file should not be readable by anyone but the user.
|
|
Note that
|
|
.Nm
|
|
ignores this file if it is accessible by others.
|
|
It is possible to
|
|
specify a passphrase when generating the key; that passphrase will be
|
|
used to encrypt the private part of this file.
|
|
This is the default file added by
|
|
.Nm
|
|
when no other files have been specified.
|
|
.It Pa $HOME/.ssh/id_dsa
|
|
Contains the DSA authentication identity of the user.
|
|
.Pp
|
|
.Sh ENVIRONMENT
|
|
.Bl -tag -width Ds
|
|
.It Ev "DISPLAY" and "SSH_ASKPASS"
|
|
If
|
|
.Nm
|
|
needs a passphrase, it will read the passphrase from the current
|
|
terminal if it was run from a terminal.
|
|
If
|
|
.Nm
|
|
does not have a terminal associated with it but
|
|
.Ev DISPLAY
|
|
and
|
|
.Ev SSH_ASKPASS
|
|
are set, it will execute the program specified by
|
|
.Ev SSH_ASKPASS
|
|
and open an X11 window to read the passphrase.
|
|
This is particularly useful when calling
|
|
.Nm
|
|
from a
|
|
.Pa .Xsession
|
|
or related script.
|
|
(Note that on some machines it
|
|
may be necessary to redirect the input from
|
|
.Pa /dev/null
|
|
to make this work.)

OpenSSH
|
|
is a derivative of the original (free) ssh 1.2.12 release, but with bugs
|
|
removed and newer features re-added.
|
|
Rapidly after the 1.2.12 release,
|
|
newer versions bore successively more restrictive licenses.
|
|
This version of OpenSSH
|
|
.Bl -bullet
|
|
.It
|
|
has all components of a restrictive nature (i.e., patents)
|
|
directly removed from the source code; any licensed or patented components
|
|
are chosen from
|
|
external libraries.
|
|
.It
|
|
has been updated to support ssh protocol 1.5.
|
|
.It
|
|
contains added support for
|
|
.Xr kerberos 8
|
|
authentication and ticket passing.
|
|
.It
|
|
supports one-time password authentication with
|
|
.Xr skey 1 .
