Start and Stop the Server

The sshd service starts automatically after installation.

A script is installed, which you can use to start, stop, and restart the sshd service. The name and location of the script varies, depending on your operating system. When you use the script to start the server, the following sshd command is invoked.

sshd -oPidFile=sshd_PidFile_keyword_value

Note: Do not use inetd to launch sshd. This is not a supported configuration. Attempting this configuration in FIPS mode results in extremely long connection times for each user connection; this is because sshd needs to run required self tests for each connection.

To run the sshd service directly

  1. Log in as root.
  2. Include full path information:

    /usr/sbin/sshd options

To run the server script on Linux

Note: The following commands work on all Linux platforms, although in some cases the actual script file is installed to a different location.

  2. Use the following commands to start, stop, and restart the sshd service:

    /etc/init.d/sshd start

    /etc/init.d/sshd stop

    /etc/init.d/sshd restart

To run the server script or service on Sun Solaris
