Introduction:
Secure shell (SSH) is a protocol that provides a secure, remote connection
to any device with ssh support. SSH is a substitute to Berkeley r-tools like
telnet, rlogin, rsh and rcp which are not secure. SSH provides more security
to any data that is being transported to the Internet by providing more authentication,
encryption and authorization procedures. There are currently two versions
of SSH available, SSH Version 1 and SSH Version 2
Required packages:
All of the required packages of this tutorial is available from http://www.sunfreeware.com

Startup Scripts:
Create a startup script for the ssh daemon.
/etc/init.d/ssh
#! /bin/sh # # start/stop the secure shell daemon case "$1" in 'start') # Start the ssh daemon if [ -f /usr/local/sbin/sshd ]; then echo "starting SSHD daemon" /usr/local/sbin/sshd & fi ;; 'stop') # Stop the ssh deamon PID=`/usr/bin/ps -e -u 0 | /usr/bin/fgrep sshd | /usr/bin/awk '{print $1}'` if [ ! -z "$PID" ] ; then /usr/bin/kill ${PID} >/dev/null 2>&1 fi ;; *) echo "usage: /etc/init.d/sshd {start|stop}" ;; esac
Make the script executable and create a startup script on run level 2.
#chmod +x /etc/init.d/sshd
#ln –s /etc/init.d/sshd /etc/rc2.d/S99sshd
Create a startup script for the pseudo random generator daemon.
/etc/init.d/prngd
#! /bin/sh # # start/stop the pseudo random generator daemon case "$1" in 'start') # Start the ssh daemon if [ -f /usr/local/bin/prngd ]; then echo "starting PRNG daemon" /usr/local/bin/prngd /var/spool/prngd/pool& fi ;; 'stop') # Stop the ssh deamon PID=`/usr/bin/ps -e -u 0 | /usr/bin/fgrep prngd | /usr/bin/awk '{print $1}'` if [ ! -z "$PID" ] ; then /usr/bin/kill ${PID} >/dev/null 2>&1 fi ;; *) echo "usage: /etc/init.d/prngd {start|stop}" ;; esac
Make the script executable and create a startup script on run level 2.
#chmod +x /etc/init.d/prngd
#ln –s /etc/init.d/prngd /etc/rc2.d/S99prngd
The errors above are due to the fact that we didn't create any key pairs for our ssh server.
Create a public key pair to support the new, DSA-based version 2 protocol
# /usr/local/bin/ssh-keygen -d -f /usr/local/etc/ssh_host_dsa_key -N ""
Generating public/private dsa key pair.
Your identification has been saved in /usr/local/etc/ssh_host_dsa_key.
Your public key has been saved in /usr/local/etc/ssh_host_dsa_key.pub.
The key fingerprint is:
00:91:f5:8a:55:7c:ac:ff:b7:08:1f:ce:23:aa:f2:79 root@solaris8
Create a public key pair to support the old, RSA-based version 1 protocol
# /usr/local/bin/ssh-keygen -b 1024 -f /usr/local/etc/ssh_host_rsa_key -t rsa
-N ""
Generating public/private rsa1 key pair.
Your identification has been saved in /usr/local/etc/ssh_host_rsa_key.
Your public key has been saved in /usr/local/etc/ssh_host_rsa_key.pub.
The key fingerprint is:
8e:b0:1d:8a:22:f2:d2:37:1f:92:96:02:e8:74:ca:ea root@solaris8
Edit ssh daemon configuration file /usr/local/etc/sshd_config, enable protocol
2 and 1
Uncomment the line, that says
protocol 2,1
# /etc/init.d//sshd start
starting SSHD daemon
#
Your ssh server is now ready to accept a ssh session.
