| 28 | .Sh NAME |
| 29 | .Nm ssh-keysign |
| 30 | .Nd ssh helper program for hostbased authentication |
| 31 | .Sh SYNOPSIS |
| Ben Lindstrom | 11d470d | 2002-06-11 15:50:13 +0000 | [diff] [blame] | 32 | .Nm |
| Ben Lindstrom | 1bad256 | 2002-06-06 19:57:33 +0000 | [diff] [blame] | 33 | .Sh DESCRIPTION |
| 34 | .Nm |
| 35 | is used by |
| 36 | .Xr ssh 1 |
| Ben Lindstrom | 11d470d | 2002-06-11 15:50:13 +0000 | [diff] [blame] | 37 | to access the local host keys and generate the digital signature |
| 38 | required during hostbased authentication with SSH protocol version 2. |
| Ben Lindstrom | 1bad256 | 2002-06-06 19:57:33 +0000 | [diff] [blame] | 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. |
| Ben Lindstrom | 11d470d | 2002-06-11 15:50:13 +0000 | [diff] [blame] | 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. |
