28 | .Sh NAME | |
29 | .Nm ssh-keysign | |
30 | .Nd ssh helper program for hostbased authentication | |
31 | .Sh SYNOPSIS | |
9cf07a6e | 32 | .Nm |
39c00dc2 | 33 | .Sh DESCRIPTION |
34 | .Nm | |
35 | is used by | |
36 | .Xr ssh 1 | |
9cf07a6e | 37 | to access the local host keys and generate the digital signature |
38 | required during hostbased authentication with SSH protocol version 2. | |
39c00dc2 | 39 | .Nm |
40 | is not intended to be invoked by the user, but from | |
41 | .Xr ssh 1 . | |
42 | See | |
43 | .Xr ssh 1 | |
44 | and | |
45 | .Xr sshd 8 | |
46 | for more information about hostbased authentication. | |
9cf07a6e | 47 | .Sh FILES |
48 | .Bl -tag -width Ds | |
49 | .It Pa /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key | |
50 | These files contain the private parts of the host keys used to | |
51 | generate the digital signature. They | |
52 | should be owned by root, readable only by root, and not | |
53 | accessible to others. | |
54 | Since they are readable only by root, | |
55 | .Nm | |
56 | must be set-uid root if hostbased authentication is used. | |
