+How to verify host keys using OpenSSH and DNS
+---------------------------------------------
+
+OpenSSH contains experimental support for verifying host keys using DNS
+as described in draft-ietf-secsh-dns-xx.txt. The document contains
+very brief instructions on how to test this feature. Configuring DNS
+and DNSSEC is out of the scope of this document.
+
+
+(1) Enable DNS fingerprint support in OpenSSH
+
+	configure --with-dns
+
+(2) Generate and publish the DNS RR
+
+To create a DNS resource record (RR) containing a fingerprint of the
+public host key, use the following command:
+
+	ssh-keygen -r hostname -f keyfile -g
+
+where "hostname" is your fully qualified hostname and "keyfile" is the
+file containing the public host key file. If you have multiple keys,
+you should generate one RR for each key.
+
+In the example above, ssh-keygen will print the fingerprint in a
+generic DNS RR format parsable by most modern name server
+implementations. If your nameserver has support for the SSHFP RR, as
+defined by the draft, you can omit the -g flag and ssh-keygen will
+print a standard RR.
+
+To publish the fingerprint using the DNS you must add the generated RR
+to your DNS zone file and sign your zone.
+
+
+(3) Enable the ssh client to verify host keys using DNS
+
+To enable the ssh client to verify host keys using DNS, you have to
+add the following option to the ssh configuration file
+($HOME/.ssh/config or /etc/ssh/ssh_config):
+
+    VerifyHostKeyDNS yes
+
+Upon connection the client will try to look up the fingerprint RR
+using DNS. If the fingerprint received from the DNS server matches
+the remote host key, the user will be notified.

-	Please don't use your production RSA keys, since
-	with the current version of sectok/ssh-keygen

-	Do not forget the passphrase.  There is no way to
-	recover if you do.
+	If you do this, anyone who has access to your card
+	can assume your identity.  This is not recommended.

-  select() under Linux is not as nice as others, and two the children
-  of the shell are not killed on exiting the shell.
-  A short run-down of what happens:
-  - The shell starts up, and starts its own session.  As a side-effect, it
-    gets its own process group.
-  - The child forks off sleep, and because it's in the background, puts it
-    into its own process group.  The sleep command inherits a copy of the
-    shell's descriptor for the tty as its stdout.
-  - The shell exits, but doesn't SIGHUP all of its child PIDs like it probably
-    should(?)
-  - The sshd server attempts to read from the master side of the pty, and
-    while there are still process with the pty open, no EOF is produced.
-  - The sleep command exits, closes its descriptor, sshd detects the EOF, and
-    the connection gets closed.
-  Ways we've tried fixing this in sshd, and why they didn't work out:
-  - SIGHUP the sshd's process group.
-    - The shell is in its own process group.
-  - Track process group IDs of all children before we reap them (via an extra
-    field in Session structures which holds the pgid for each child pid), and
-    SIGHUP the pgid when we reap.
-    - Background commands are in yet another process group.
-  - Close the connection when the child dies.
-    - Background commands may need to write data to the connection.  Also
-      prematurely truncates output from some commands (scp server, the
-      famous "dd if=/dev/zero bs=1000 count=100" case).
-  Known workarounds:
-  - bash: shopt huponexit on
-  - tcsh: none
-  - zsh: setopt HUP (usually the default setting)
-    (taken from email from Jason Stone to openssh-unix-dev, 5 May 2001)

+Overview.
+
+$ ./configure && make tests
+
+You'll see some progress info. A failure will cause either the make to
+abort or the driver script to report a "FATAL" failure.
+
+The test consists of 2 parts. The first is the file-based tests which is
+driven by the Makefile, and the second is a set of network or proxycommand
+based tests, which are driven by a driver script (test-exec.sh) which is
+called multiple times by the Makefile.
+
+Failures in the first part will cause the Makefile to return an error.
+Failures in the second part will print a "FATAL" message for the failed
+test and continue.
+
+OpenBSD has a system-wide regression test suite. OpenSSH Portable's test
+suite is based on OpenBSD's with modifications.
+
+
+Environment variables.
+
+SUDO: path to sudo command, if desired. Note that some systems (notably
+	systems using PAM) require sudo to execute some tests.
+TEST_SSH_TRACE: set yo "yes" for verbose output from tests 
+TEST_SSH_QUIET: set to "yes" to suppress non-fatal output.
+TEST_SSH_x: path to "ssh" command under test, where x=SSH,SSHD,SSHAGENT,SSHADD
+	SSHKEYGEN,SSHKEYSCAN,SFTP,SFTPSERVER
+OBJ: used by test scripts to access build dir.
+
+
+Individual tests.
+
+You can invoke test-exec.sh directly if you set up the path to find the
+binaries under test and the test scripts themselves, for example:
+
+$ cd regress
+$ PATH=`pwd`/..:$PATH:. sh test-exec.sh `pwd` agent-timeout.sh
+ok agent timeout test
+
+
+Files.
+
+test-exec.sh: the main test driver. Sets environment, creates config files
+and keys and runs the specified test.
+
+At the time of writing, the individual tests are:
+agent-timeout.sh:	agent timeout test
+agent.sh:		simple agent test
+broken-pipe.sh:		broken pipe test
+connect-privsep.sh:	proxy connect with privsep
+connect.sh:		simple connect
+exit-status.sh:		remote exit status
+forwarding.sh:		local and remote forwarding
+keygen-change.sh:	change passphrase for key
+keyscan.sh:		keyscan
+proto-mismatch.sh:	protocol version mismatch
+proto-version.sh:	sshd version with different protocol combinations
+proxy-connect.sh:	proxy connect
+sftp.sh:		basic sftp put/get
+ssh-com-client.sh:	connect with ssh.com client
+ssh-com-keygen.sh:	ssh.com key import
+ssh-com-sftp.sh:	basic sftp put/get with ssh.com server
+ssh-com.sh:		connect to ssh.com server
+stderr-after-eof.sh:	stderr data after eof
+stderr-data.sh:		stderr data transfer
+transfer.sh:		transfer data
+try-ciphers.sh:		try ciphers
+yes-head.sh:		yes pipe head
+
+
+Problems?
+
+Run the failing test with shell tracing (-x) turned on:
+$ PATH=`pwd`/..:$PATH:. sh -x test-exec.sh `pwd` agent-timeout.sh
+
+Failed tests can be difficult to diagnose. Suggestions:
+- run the individual test via ./test-exec.sh `pwd` [testname]
+- set LogLevel to VERBOSE in test-exec.sh and enable syslogging of
+  auth.debug (eg to /var/log/authlog).
+
+
+Known Issues.

+may be used to generate groups for the Diffie-Hellman Group Exchange
+(DH-GEX) protocol.
+Generating these groups is a two-step process: first, candidate
+primes are generated using a fast, but memory intensive process.
+These candidate primes are then tested for suitability (a CPU-intensive
+process).
+.Pp
+Generation of primes is performed using the
+.Fl G
+option.
+The desired length of the primes may be specified by the
+.Fl b
+option.
+For example:
+.Pp
+.Dl ssh-keygen -G moduli-2048.candidates -b 2048
+.Pp
+By default, the search for primes begins at a random point in the
+desired length range.
+This may be overridden using the
+.Fl S
+option, which specifies a different start point (in hex).
+.Pp
+Once a set of candidates have been generated, they must be tested for
+suitability.
+This may be performed using the
+.Fl T
+option.
+In this mode
+.Nm
+will read candidates from standard input (or a file specified using the
+.Fl f
+option).
+For example:
+.Pp
+.Dl ssh-keygen -T moduli-2048 -f moduli-2048.candidates
+.Pp
+By default, each candidate will be subjected to 100 primality tests.
+This may be overridden using the
+.Fl a
+option.
+The DH generator value will be chosen automatically for the
+prime under consideration.
+If a specific generator is desired, it may be requested using the
+.Fl W
+option.
+Valid generator values are 2, 3 and 5.
