You will need working installations of Zlib and OpenSSL.
-Zlib 1.1.4 or greater:
+Zlib:
http://www.gzip.org/zlib/
-OpenSSL 0.9.6 or greater:
+OpenSSL 0.9.5a or greater:
http://www.openssl.org/
-(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
-Blowfish) do not work correctly.)
+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.
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-pam enables PAM support. If PAM support is compiled in, it must
-also be enabled in sshd_config (refer to the UsePAM directive).
+--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
--without-lastlog will disable lastlog support entirely.
---with-osfsia, --without-osfsia will enable or disable OSF1's Security
+--with-sia, --without-sia 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
+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=PATH will enable S/Key one time password support. You will
need the S/Key libraries and header files installed for this to work.
--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 / gssapi-openssh.git / blobdiff
