How to Install OpenSSH in Sun Solaris 9 (SPARC)

OpenSSH is a free opensource version of the SSH connectivity tools. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks unlike Telnet,rlogin or ftp where the data is not encrypted and transmitted in plain text. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.

The easiest way to install OpenSSH in Sun Solaris is to use the pre-compiled packages from sunfreeware.

The following are the packages that are required to be installed for OpenSSH to work properly in Solaris 9:

OpenSSL (Latest stable: openssl-0.9.8f)

ZLib (Latest stable: zlib-1.2.3)

GNU Compiler Collection (gcc Latest stable: libgcc-3.4.6)

TCPWrapper (Optional tcp_wrappers-7.6)

and OpenSSH itself (Latest Stable: openssh-4.7p1)

To start of, download the packages from the following links Solaris 9 SPARC:





Once done, upload the files onto the server so we can start to unzip the files and install.

Unzip and install gcc

solaris9# gunzip libgcc-3.4.6-sol9-sparc-local.gz

solaris9# pkgadd -d libgcc-3.4.6-sol9-sparc-local

Installation of <SMCgcc> was successful.

Unzip and install zlib

solaris9# gunzip  zlib-1.2.3-sol9-sparc-local.gz

solaris9# pkgadd -d zlib-1.2.3-sol9-sparc-local

Installation of <SMCzlib> was successful.

Unzip and install OpenSSL

solaris9# gunzip openssl-0.9.8f-sol9-sparc-local.gz

solaris9# pkgadd -d openssl-0.9.8f-sol9-sparc-local

Installation of <SMCossl> was successful.

Unzip and install OpenSSH

solaris9# gunzip openssh-4.7p1-sol9-sparc-local.gz

solaris9# pkgadd -d openssh-4.7p1-sol9-sparc-local

Installation of <SMCossl> was successful.

The packages are now installed.

Create /var/empty directory

solaris9# mkdir /var/empty

Change directory ownership to Root user and sys group

solaris9# chown root:sys /var/empty

Change permissions

solaris9# chmod 755 /var/empty

Add sshd user & group

solaris9# groupadd ssh

solaris9# # useradd -g sshd -c ‘sshd privsep’ -d /var/empty -s /bin/false sshd

Edit the default /usr/local/sshd_config file and make the following changes:

Replace the line

Subsystem sftp /usr/libexec/sftp-server


Subsystem sftp /usr/local/libexec/sftp-server

Generate Keys for the server

solaris9# ssh-keygen -t rsa1 -f /usr/local/etc/ssh_host_key -N “”
solaris9# ssh-keygen -t dsa -f /usr/local/etc/ssh_host_dsa_key -N “”
solaris9# ssh-keygen -t rsa -f /usr/local/etc/ssh_host_rsa_key -N “”

sshd at Solaris startup

Add a startup script /etc/init.d/sshd as follows to enable the OpenSSH server daemon “sshd” at the startup

case “$1” in
        if [ -x /usr/local/sbin/sshd ]; then
                echo “Starting the secure shell daemon”
                /usr/local/sbin/sshd &

        echo “Stopping the secure shell daemon ”
        pkill -TERM sshd
        echo “Usage: /etc/init.d/sshd { start | stop }”
exit 0

Change the ownership & permissions on the startup script

solaris9# chown root:sys /etc/init.d/sshd
solaris9# chmod 555 /etc/init.d/sshd

Create a Symlink to the startup script at /etc/rc2/d/S98sshd

# ln -s /etc/init.d/sshd /etc/rc2.d/S98sshd

That is it. All done and ready to go. Try connecting to the server using a ssh client like PUTTY.
