You will need working installations of Zlib and OpenSSL.
Zlib:
-http://www.freesoftware.com/pub/infozip/zlib/
+http://www.gzip.org/zlib/
-OpenSSL 0.9.5a or greater:
+OpenSSL 0.9.6 or greater:
http://www.openssl.org/
-RPMs of OpenSSL are available at http://violet.ibs.com.au/openssh/files/support.
-For Red Hat Linux 6.2, they have been released as errata. RHL7 includes
-these.
+(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
+Blowfish) do not work correctly.)
OpenSSH can utilise Pluggable Authentication Modules (PAM) if your system
supports it. PAM is standard on Redhat and Debian Linux, Solaris and
HP-UX 11.
+NB. If you operating system supports /dev/random, you should configure
+OpenSSL to use it. OpenSSH relies on OpenSSL's direct support of
+/dev/random. If you don't you will have to rely on ssh-rand-helper, which
+is inferior to a good kernel-based solution.

Alternatively, Jim Knoble <jmknoble@jmknoble.cx> has written an excellent X11
passphrase requester. This is maintained separately at:

PRNGD:

-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.
-
-PCRE (PERL-compatible Regular Expression library):
-ftp://ftp.cus.cam.ac.uk/pub/software/programing/pcre/
-
-Most platforms do not require this. However older Unices may not have a
-posix regex library. PCRE provides a POSIX interface.

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.
-
--with-pam enables PAM support.
--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 absolutely
-sure of what you are doing, it is best to leave this alone.
-
--with-prngd-socket=/some/file allows you to enable EGD or PRNGD
support and to specify a PRNGd socket. Use this if your Unix lacks
/dev/random and you don't want to use OpenSSH's builtin entropy
--without-lastlog will disable lastlog support entirely.
---with-sia, --without-sia will enable or disable OSF1's Security
+--with-osfsia, --without-osfsia will enable or disable OSF1's Security
Integration Architecture. The default for OSF1 machines is enable.
--with-kerberos4=PATH will enable Kerberos IV support. You will need
--with-xauth=PATH specifies the location of the xauth binary
---with-ipv4-default instructs OpenSSH to use IPv4 by default for new
-connections. Normally OpenSSH will try attempt to lookup both IPv6 and
-IPv4 addresses. On Linux/glibc-2.1.2 this causes long delays in name
-resolution. If this option is specified, you can still attempt to
-connect to IPv6 addresses using the command line option '-6'.
-
--with-ssl-dir=DIR allows you to specify where your OpenSSL libraries
are installed.
--with-4in6 Check for IPv4 in IPv6 mapped addresses and convert them to
real (AF_INET) IPv4 addresses. Works around some quirks on Linux.
+--with-opensc=DIR
+--with-sectok=DIR allows for OpenSC or sectok smartcard libraries to
+be used with OpenSSH. See 'README.smartcard' for more details.
+
If you need to pass special options to the compiler or linker, you
can specify these as environment variables before running ./configure.
For example:
andersk / openssh.git / blobdiff
