<title>Installation of <application>Open<acronym>SSH</acronym></application></title>

<para><application>Open<acronym>SSH</acronym></application> runs as two 
processes when connecting to other
computers. The first process is a privileged process and controls the
issuance of privileges as necessary. The second process communicates
with the network. Additional installation steps are necessary to set up
the proper environment which are performed by the following
commands:</para>

<screen><userinput><command>mkdir /var/empty &amp;&amp;
chown root:sys /var/empty &amp;&amp;
groupadd sshd &amp;&amp;
useradd -c 'sshd privsep' -d /var/empty -g sshd -s /bin/false sshd</command></userinput></screen>

<para><application>OpenSSH</application> is very sensitive to changes in the
linked <application>OpenSSL</application> libraries. If you recompile
<application>OpenSSL</application>, <application>OpenSSH</application> may
fail to startup. An alternative is to link against the static <application>OpenSSL</application>
library. To link against the static library, execute the following command:</para>

<screen><userinput><command>sed -i "s:-lcrypto:/usr/lib/libcrypto.a:g" configure</command></userinput></screen>

<para>Install <application>Open<acronym>SSH</acronym></application> by running 
the following commands:</para>

<screen><userinput><command>./configure --prefix=/usr --sysconfdir=/etc/ssh \
    --libexecdir=/usr/sbin --with-md5-passwords &amp;&amp;
make &amp;&amp;
make install</command></userinput></screen>
