SSH-KEYSIGN(8)SSH-KEYSIGN(8)NAMEssh-keysign - ssh helper program for host-based authentication
SYNOPSISssh-keysignDESCRIPTIONssh-keysign is used by ssh(1) to access the local host keys and gener‐
ate the digital signature required during host-based authentication
with SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the
global client configuration file /opt/ssh/etc/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 authenti‐
cation.
FILES
/opt/ssh/etc/ssh_config
Controls whether ssh-keysign is enabled.
/opt/ssh/etc/ssh_host_dsa_key, /opt/ssh/etc/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 privileged users, and not accessible to others.
Since they are readable only by privileged users, ssh-keysign
must be set-uid to a privileged user if host-based authentica‐
tion is used.
HISTORY
HP-UX Secure Shell is based on OpenSSH version 5.2p1
