ssh-keygen: passphrase.

[Sunil K. Vallamkonda]

Looking at openSSH INSTALL:

To generate a host key, run "make host-key". Alternately you can do so
manually using the following commands:

    ssh-keygen -b 1024 -f /etc/ssh/ssh_host_key -N ""
    ssh-keygen -d -f /etc/ssh/ssh_host_dsa_key -N ""

But when I try latter, I get:

(gdb) n
1  0x35a6 in save_private_key_ssh2 (
    filename=0xb2d2c "/mydir/ssh_host_dsa_key",
    _passphrase=0xb90f0 "''", key=0xc0360, comment=0xefbf91b0
"user at host")
    at authfile.c:172

^^^^^^^^^
This means:

In authfile.c - save_private_key_ssh2(..):

<clipped>
    if (len > 0 && len <= 4) {
        error("passphrase too short: %d bytes", len);
        errno = 0;
        return 0;
    }

<clipped>


Any ideas why this check, when INSTALL says passphrase not required ?

Thx.

Sunil.
