NAME
ssh-keysign
- OpenSSH helper for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign
is used by
ssh(1)
to access the local host keys and generate the digital signature
required during host-based authentication.
ssh-keysign
is disabled by default and can only be enabled in the
global client configuration file
/etc/ssh/ssh_config
by setting
EnableSSHKeysign
to
``yes''
ssh-keysign
is not intended to be invoked by the user, but from
ssh(1).
See
ssh(1)
and
sshd(8)
for more information about host-based authentication.
FILES
- /etc/ssh/ssh_config
-
Controls whether
ssh-keysign
is enabled.
- /etc/ssh/ssh_host_dsa_key
-
- /etc/ssh/ssh_host_ecdsa_key
-
- /etc/ssh/ssh_host_ed25519_key
-
- /etc/ssh/ssh_host_rsa_key
-
These files contain the private parts of the host keys used to
generate the digital signature.
They should be owned by root, readable only by root, and not
accessible to others.
Since they are readable only by root,
ssh-keysign
must be set-uid root if host-based authentication is used.
- /etc/ssh/ssh_host_dsa_key-cert.pub
-
- /etc/ssh/ssh_host_ecdsa_key-cert.pub
-
- /etc/ssh/ssh_host_ed25519_key-cert.pub
-
- /etc/ssh/ssh_host_rsa_key-cert.pub
-
If these files exist, they are assumed to contain public certificate
information corresponding with the private keys above.
