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-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
to have the Kerberos libraries and header files installed for this
to work. Use the optional PATH argument to specify the root of your
--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
