Configuring OpenSSH
Config files
/etc/ssh/ssh_config,
/etc/ssh/sshd_config
There are no required changes in either of these files. However
you may wish to view them to make changes for appropriate security to
your system. Configuration information can be found in the man pages for
sshd, ssh and ssh-agent
sshd init.d script
Note that you only want to start the sshd server if
you want to be able to ssh into your
machine. The ssh client doesn't need this script to be
used. Having said that, if you want to run the ssh daemon,
the OpenSSH daemon init.d script can be created using the following
commands:
cat > /etc/rc.d/init.d/sshd << "EOF"
#!/bin/sh
# Begin $rc_base/init.d/sshd
# Based on sysklogd script from LFS-3.1 and earlier.
