<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 &&
|
|
chown root:sys /var/empty &&
|
|
groupadd sshd &&
|
|
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. To avoid this, it is possible to link to
|
|
<application>OpenSSL</application> libraries. If you prefer this, execute the
|
|
following commands:</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 &&
|
|
make &&
|
|
make install</command></userinput></screen>
