1. Prerequisites
|
|
----------------
|
|
|
|
You will need working installations of Zlib and OpenSSL.
|
|
|
|
Zlib:
|
|
http://www.cdrom.com/pub/infozip/zlib/
|
|
|
|
OpenSSL:
|
|
http://www.openssl.org/
|
|
|
|
OpenSSH can utilise Pluggable Authentication Modules (PAM) if your system
|
|
supports it. PAM is standard on Redhat and Debian Linux and on Solaris.
|
|
|
|
PAM:
|
|
http://www.kernel.org/pub/linux/libs/pam/
|
|
|
|
Dante:
|
|
http://www.inet.no/dante
|
|
|
|
OpenSSH can also use the Dante SOCKS libraries, version 1.1.1pre1 or higher,
|
|
if you have them installed on your system.
|
|
|
|
If you wish to build the GNOME passphrase requester, you will need the GNOME
|
|
libraries and headers.
|
|
|
|
GNOME:
|
|
http://www.gnome.org/
|
|
|
|
Alternatly Jim Knoble <jmknoble@pobox.com> has written an excellent X11
|
|
passphrase requester. This is maintained seperatly at:
|
|
|
|
http://www.pobox.com/~jmknoble/jmk/
|
|
|
|
|
|
If you are planning to use OpenSSH on a Unix which lacks a Kernel random
|
|
number generator (/dev/urandom), you will need to install the Entropy
|
|
Gathering Daemon (or similar). You will also need to specify the
|
|
--with-egd-pool option to ./configure.
|
|
|
|
EGD:
|
|
http://www.lothar.com/tech/crypto/
|
|
|
|
GNU Make:
|
|
ftp://ftp.gnu.org/gnu/make/
|
|
|
|
OpenSSH has only been tested with GNU make. It may work with other
|
|
'make' programs, but you are on your own.
|
|
|
|
2. Building / Installation
|
|
--------------------------
|
|
|
|
To install OpenSSH with default options:
|
|
|
|
./configure
|
|
make
|
|
make install
|
|
|
|
This will install the OpenSSH binaries in /usr/local/bin, configuration files
|
|
in /usr/local/etc, the server in /usr/local/sbin, etc. To specify a different
|
|
installation prefix, use the --prefix option to configure:
|
|
|
|
./configure --prefix=/opt
|
|
make
|
|
make install
|
|
|
|
Will install OpenSSH in /opt/{bin,etc,lib,sbin}. You can also override
|
|
specific paths, for example:
|
|
|
|
./configure --prefix=/opt --sysconfdir=/etc/ssh
|
|
make
|
|
make install
|
|
|
|
This will install the binaries in /opt/{bin,lib,sbin}, but will place the
|
|
configuration files in /etc/ssh.
|
|
|
|
If you are using PAM, you will need to manually install a PAM control
|
|
file as "/etc/pam.d/sshd" (or wherever your system prefers to keep
|
|
them). A generic PAM configuration is included as "sshd.pam.generic",
|
|
you may need to edit it before using it on your system.
|
|
|
|
There are a few other options to the configure script:
|
|
|
|
--with-rsh=PATH allows you to specify the path to your rsh program.
|
|
Normally ./configure will search the current $PATH for 'rsh'. You
|
|
may need to specify this option if rsh is not in your path or has a
|
|
different name.
|
|
|
|
--without-pam will disable PAM support. PAM is automatically detected
|
|
and switched on if found.
|
|
|
|
--enable-gnome-askpass will build the GNOME passphrase dialog. You
|
|
need a working installation of GNOME, including the development
|
|
headers, for this to work.
|
|
|
|
--with-random=/some/file allows you to specify an alternate source of
|
|
random numbers (the default is /dev/urandom). Unless you are absolutly
|
|
sure of what you are doing, it is best to leave this alone.
|
|
|
|
--with-egd-pool=/some/file allows you to enable Entropy Gathering
|
|
Daemon support and to specify a EGD pool socket. You will need to
|
|
use this if your Unix does not support the /dev/urandom device (or
|
|
similar). The file argument refers to the EGD pool file, not the
|
|
EGD program itself. Please refer to the EGD documentation.
|
|
|
|
--with-lastlog=FILE will specify the location of the lastlog file.
|
|
./configure searches a few locations for lastlog, but may not find
|
|
it if lastlog is installed in a different place.
|
|
|
|
--without-lastlog will disable lastlog support entirely.
|
|
|
|
--with-kerberos4=PATH will enable Kerberos IV support. You will need
|
|
to have the Kerberos libraries and header files installed for this
|
|
to work. Use the optional PATH argument to specify the root of your
|
|
Kerberos installation.
|
|
|
|
--with-afs=PATH will enable AFS support. You will need to have the
|
|
Kerberos IV and the AFS libraries and header files installed for this
|
|
to work. Use the optional PATH argument to specify the root of your
|
|
AFS installation. AFS requires Kerberos support to be enabled.
|
|
|
|
--with-skey will enable S/Key one time password support. You will need
|
|
the S/Key libraries and header files installed for this to work.
|
|
|
|
--with-tcp-wrappers will enable TCP Wrappers (/etc/hosts.allow|deny)
|
|
support. You will need libwrap.a and tcpd.h installed.
|
|
|
|
--with-md5-passwords will enable the use of MD5 passwords. Enable this
|
|
if your operating system uses MD5 passwords without using PAM.
|
|
|
|
--with-utmpx enables utmpx support. utmpx support is automatic for
|
|
some platforms.
|
|
|
|
--without-shadow disables shadow password support.
|
|
|
|
--with-ipaddr-display forces the use of a numeric IP address in the
|
|
$DISPLAY environment variable. Some broken systems need this.
|
|
|
|
--with-default-path=PATH allows you to specify a default $PATH for sessions
|
|
started by sshd.
|
|
|
|
--with-dante[=DIR] will enable Dante SOCKS library support. If the Dante
|
|
libsocks library isn't installed in a library searched by the compiler,
|
|
add the directory name as the option.
|
|
|
|
If you need to pass special options to the compiler or linker, you
|
|
can specify these as enviornment variables before running ./configure.
|
|
For example:
|
|
|
|
CFLAGS="-O -m486" LFLAGS="-s" ./configure
|
|
|
|
3. Configuration
|
|
----------------
|
|
|
|
The runtime configuration files are installed by in ${prefix}/etc or
|
|
whatever you specified as your --sysconfdir (/usr/local/etc by default).
|
|
|
|
The default configuration should be instantly usable, though you should
|
|
review it to ensure that it matches your security requirements.
|
|
|
|
To generate a host key, issue the following command: (replacing
|
|
/etc/ssh/ssh_host_key with an appropriate path)
|
|
|
|
/usr/bin/ssh-keygen -b 1024 -f /etc/ssh/ssh_host_key -N ''
|
|
|
|
Replacing /etc/ssh with the correct path to the configuration directory.
|
|
(${prefix}/etc or whatever you specified with --sysconfdir during
|
|
configuration)
|
|
|
|
If you have configured OpenSSH with EGD support, ensure that EGD is
|
|
running and has collected some Entropy.
|
|
|
|
For more information on configuration, please refer to the manual pages
|
|
for sshd, ssh and ssh-agent.
|
|
|
|
