                     25: .Nm
1.1       deraadt    26: adds identities to the authentication agent,
1.2       deraadt    27: .Xr ssh-agent 1 .
1.1       deraadt    28: When run without arguments, it adds the file
1.2       deraadt    29: .Pa $HOME/.ssh/identity .
1.1       deraadt    30: Alternative file names can be given on the
                     31: command line.  If any file requires a passphrase,
1.2       deraadt    32: .Nm
1.4       markus     33: asks for the passphrase from the user.
                     34: The Passphrase it is read from the user's tty.
1.2       deraadt    35: .Pp
1.1       deraadt    36: The authentication agent must be running and must be an ancestor of
                     37: the current process for
1.2       deraadt    38: .Nm
1.1       deraadt    39: to work.
1.2       deraadt    40: .Pp
                     41: The options are as follows:
                     42: .Bl -tag -width Ds
                     43: .It Fl l
1.1       deraadt    44: Lists all identities currently represented by the agent.
1.2       deraadt    45: .It Fl d
1.1       deraadt    46: Instead of adding the identity, removes the identity from the agent.
1.2       deraadt    47: .It Fl D
1.1       deraadt    48: Deletes all identities from the agent.
1.2       deraadt    49: .El
                     50: .Sh FILES
                     51: .Bl -tag -width Ds
                     52: .Pa $HOME/.ssh/identity
1.1       deraadt    53: Contains the RSA authentication identity of the user.  This file
1.4       markus     54: should not be readable by anyone but the user.
                     55: Note that
                     56: .Nm
                     57: ignores this file if it is accessible by others.
                     58: It is possible to
1.1       deraadt    59: specify a passphrase when generating the key; that passphrase will be
                     60: used to encrypt the private part of this file.  This is the
                     61: default file added by
1.2       deraadt    62: .Nm
1.1       deraadt    63: when no other files have been specified.
1.2       deraadt    64: .Pp
1.1       deraadt    65: If
1.2       deraadt    66: .Nm
1.1       deraadt    67: needs a passphrase, it will read the passphrase from the current
                     68: terminal if it was run from a terminal.  If
1.2       deraadt    69: .Nm
1.1       deraadt    70: does not have a terminal associated with it but
1.2       deraadt    71: .Ev DISPLAY
1.1       deraadt    72: is set, it
                     73: will open an X11 window to read the passphrase.  This is particularly
                     74: useful when calling
1.2       deraadt    75: .Nm
                     76: from a
                     77: .Pa .Xsession
                     78: or related script.  (Note that on some machines it
                     79: may be necessary to redirect the input from
                     80: .Pa /dev/null
                     81: to make this work.)

1.5       deraadt    85: OpenSSH
                     86: is a derivative of the original (free) ssh 1.2.12 release, but with bugs
                     87: removed and newer features re-added.   Rapidly after the 1.2.12 release,
                     88: newer versions bore successively more restrictive licenses.  This version
                     89: of OpenSSH

                     93: .Xr ssl 8 )
                     94: directly removed from the source code; any licensed or patented components
                     95: are chosen from
                     96: external libraries.
                     97: .It
                     98: has been updated to support ssh protocol 1.5.
                     99: .It
                    100: contains added support for
                    101: .Xr kerberos 8
                    102: authentication and ticket passing.
                    103: .It
                    104: supports one-time password authentication with
