Client and
Server
Secure file copy for client and server
scp
ftp
ClientSecure FTP program
sftp
ftpd
Server
The sftp server subsystem automatically initiated
by the sshd daemon.
sftp-server
Not applicableServer
Random number generator used when the sshd
daemon is unable to find the /dev/random or /dev/
urandom file on the server
prngd
Not applicableClient and
Server
Generates key pairs used in public-key authentication.
Both client and server are required to generate key
pairs. The server key pair is required for all HP-UX
Secure Shell client operations regardless of the
authentication method used. The client key pair is
used for public-key authentication only.
ssh-keygen
Not applicableClientTool for automatic public-key login from client to
server. The ssh-agent binary stores information
about the private-key passcodes for different client
users on the system. During public-key authentication,
the client prompts the user for the private-key
passcode. However, if ssh-agent is running at the
same time, the client retrieves the passcode from the
ssh-agent binary.
ssh-agent
Not applicableClient
Makes the client key pairs known to ssh-agent.
Useful during public-key authentication if the client’s
private keys are generated with passcodes.
ssh-add
Not applicableClientGathers public keys for a set of systems running the
sshd daemon.
ssh-keyscan
Not applicableClientThe client uses this command to read the server’s
private key. The ssh-keysign binary runs as a
superuser and is not visible to end users.
ssh-keysign
Keys and Configuration Files
A run-time HP-UX Secure Shell environment uses the following files for authentication:
• Configuration files
• Host file lists
• Key files
Table 1-3 lists the client keys and configuration files for the HP-UX Secure Shell client.
Table 1-3 Client Keys and Configuration Files
LocationDescriptionName
/opt/ssh/etc/ssh_config
Specifies the client configuration
file. The client uses this file to
determine the required run-time
parameters. For more information
on the configuration directives in
the ssh_config file, see
Appendix A (page 67).
