+NTP 4.2.8p7 (Harlan Stenn , 2016/04/26)
-NTP 4.2.8p6
+Focus: Security, Bug fixes, enhancements.
+
+Severity: MEDIUM
+
+When building NTP from source, there is a new configure option
+available, --enable-dynamic-interleave. More information on this below.
+
+Also note that ntp-4.2.8p7 logs more "unexpected events" than previous
+versions of ntp. These events have almost certainly happened in the
+past, it's just that they were silently counted and not logged. With
+the increasing awareness around security, we feel it's better to clearly
+log these events to help detect abusive behavior. This increased
+logging can also help detect other problems, too.
+
+In addition to bug fixes and enhancements, this release fixes the
+following 9 low- and medium-severity vulnerabilities:
+
+* Improve NTP security against buffer comparison timing attacks,
+ AKA: authdecrypt-timing
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 2879 / CVE-2016-1550
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSSv2: LOW 2.6 - (AV:L/AC:H/Au:N/C:P/I:P/A:N)
+ CVSSv3: MED 4.0 - CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N
+ Summary: Packet authentication tests have been performed using
+ memcmp() or possibly bcmp(), and it is potentially possible
+ for a local or perhaps LAN-based attacker to send a packet with
+ an authentication payload and indirectly observe how much of
+ the digest has matched.
+ Mitigation:
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page.
+ Properly monitor your ntpd instances.
+ Credit: This weakness was discovered independently by Loganaden
+ Velvindron, and Matthew Van Gundy and Stephen Gray of Cisco ASIG.
+
+* Zero origin timestamp bypass: Additional KoD checks.
+ References: Sec 2945 / Sec 2901 / CVE-2015-8138
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7,
+ Summary: Improvements to the fixes incorporated in t 4.2.8p6 and 4.3.92.
+
+* peer associations were broken by the fix for NtpBug2899
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 2952 / CVE-2015-7704
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSSv2: MED 4.3 - (AV:N/AC:M/Au:N/C:N/I:N/A:P)
+ Summary: The fix for NtpBug2952 in ntp-4.2.8p5 to address broken peer
+ associations did not address all of the issues.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ If you can't upgrade, use "server" associations instead of
+ "peer" associations.
+ Monitor your ntpd instances.
+ Credit: This problem was discovered by Michael Tatarinov.
+
+* Validate crypto-NAKs, AKA: CRYPTO-NAK DoS
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3007 / CVE-2016-1547 / VU#718152
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSS2: MED 4.3 - (AV:N/AC:M/Au:N/C:N/I:N/A:P)
+ CVSS3: MED 3.7 - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L
+ Summary: For ntp-4 versions up to but not including ntp-4.2.8p7, an
+ off-path attacker can cause a preemptable client association to
+ be demobilized by sending a crypto NAK packet to a victim client
+ with a spoofed source address of an existing associated peer.
+ This is true even if authentication is enabled.
+
+ Furthermore, if the attacker keeps sending crypto NAK packets,
+ for example one every second, the victim never has a chance to
+ reestablish the association and synchronize time with that
+ legitimate server.
+
+ For ntp-4.2.8 thru ntp-4.2.8p6 there is less risk because more
+ stringent checks are performed on incoming packets, but there
+ are still ways to exploit this vulnerability in versions before
+ ntp-4.2.8p7.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ Properly monitor your =ntpd= instances
+ Credit: This weakness was discovered by Stephen Gray and
+ Matthew Van Gundy of Cisco ASIG.
+
+* ctl_getitem() return value not always checked
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3008 / CVE-2016-2519
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSSv2: MED 4.9 - (AV:N/AC:H/Au:S/C:N/I:N/A:C)
+ CVSSv3: MED 4.2 - CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H
+ Summary: ntpq and ntpdc can be used to store and retrieve information
+ in ntpd. It is possible to store a data value that is larger
+ than the size of the buffer that the ctl_getitem() function of
+ ntpd uses to report the return value. If the length of the
+ requested data value returned by ctl_getitem() is too large,
+ the value NULL is returned instead. There are 2 cases where the
+ return value from ctl_getitem() was not directly checked to make
+ sure it's not NULL, but there are subsequent INSIST() checks
+ that make sure the return value is not NULL. There are no data
+ values ordinarily stored in ntpd that would exceed this buffer
+ length. But if one has permission to store values and one stores
+ a value that is "too large", then ntpd will abort if an attempt
+ is made to read that oversized value.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ Properly monitor your ntpd instances.
+ Credit: This weakness was discovered by Yihan Lian of the Cloud
+ Security Team, Qihoo 360.
+
+* Crafted addpeer with hmode > 7 causes array wraparound with MATCH_ASSOC
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3009 / CVE-2016-2518 / VU#718152
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSS2: LOW 2.1 - (AV:N/AC:H/Au:S/C:N/I:N/A:P)
+ CVSS3: LOW 2.0 - CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L
+ Summary: Using a crafted packet to create a peer association with
+ hmode > 7 causes the MATCH_ASSOC() lookup to make an
+ out-of-bounds reference.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ Properly monitor your ntpd instances
+ Credit: This weakness was discovered by Yihan Lian of the Cloud
+ Security Team, Qihoo 360.
+
+* remote configuration trustedkey/requestkey/controlkey values are not
+ properly validated
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3010 / CVE-2016-2517 / VU#718152
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSS2: MED 4.9 - (AV:N/AC:H/Au:S/C:N/I:N/A:C)
+ CVSS3: MED 4.2 - CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H
+ Summary: If ntpd was expressly configured to allow for remote
+ configuration, a malicious user who knows the controlkey for
+ ntpq or the requestkey for ntpdc (if mode7 is expressly enabled)
+ can create a session with ntpd and then send a crafted packet to
+ ntpd that will change the value of the trustedkey, controlkey,
+ or requestkey to a value that will prevent any subsequent
+ authentication with ntpd until ntpd is restarted.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ Properly monitor your =ntpd= instances

+ Security Team, Qihoo 360.
+
+* Duplicate IPs on unconfig directives will cause an assertion botch in ntpd
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3011 / CVE-2016-2516 / VU#718152
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSS2: MED 6.3 - (AV:N/AC:M/Au:S/C:N/I:N/A:C)
+ CVSS3: MED 4.2 - CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H
+ Summary: If ntpd was expressly configured to allow for remote
+ configuration, a malicious user who knows the controlkey for
+ ntpq or the requestkey for ntpdc (if mode7 is expressly enabled)
+ can create a session with ntpd and if an existing association is
+ unconfigured using the same IP twice on the unconfig directive
+ line, ntpd will abort.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ Properly monitor your ntpd instances
+ Credit: This weakness was discovered by Yihan Lian of the Cloud
+ Security Team, Qihoo 360.
+
+* Refclock impersonation vulnerability
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3020 / CVE-2016-1551
+ Affects: On a very limited number of OSes, all NTP releases up to but
+ not including 4.2.8p7, and 4.3.0 up to but not including 4.3.92.
+ By "very limited number of OSes" we mean no general-purpose OSes
+ have yet been identified that have this vulnerability.
+ CVSSv2: LOW 2.6 - (AV:N/AC:H/Au:N/C:N/I:P/A:N)
+ CVSSv3: LOW 3.7 - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N
+ Summary: While most OSes implement martian packet filtering in their
+ network stack, at least regarding 127.0.0.0/8, some will allow
+ packets claiming to be from 127.0.0.0/8 that arrive over a
+ physical network. On these OSes, if ntpd is configured to use a
+ reference clock an attacker can inject packets over the network
+ that look like they are coming from that reference clock.
+ Mitigation:
+ Implement martian packet filtering and BCP-38.
+ Configure ntpd to use an adequate number of time sources.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page
+ If you are unable to upgrade and if you are running an OS that
+ has this vulnerability, implement martian packet filters and
+ lobby your OS vendor to fix this problem, or run your
+ refclocks on computers that use OSes that are not vulnerable
+ to these attacks and have your vulnerable machines get their
+ time from protected resources.
+ Properly monitor your ntpd instances.
+ Credit: This weakness was discovered by Matt Street and others of
+ Cisco ASIG.
+
+The following issues were fixed in earlier releases and contain
+improvements in 4.2.8p7:
+
+* Clients that receive a KoD should validate the origin timestamp field.
+ References: Sec 2901 / CVE-2015-7704, CVE-2015-7705
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7,
+ Summary: Improvements to the fixes incorporated into 4.2.8p4 and 4.3.77.
+
+* Skeleton key: passive server with trusted key can serve time.
+ References: Sec 2936 / CVE-2015-7974
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7,
+ Summary: Improvements to the fixes incorporated in t 4.2.8p6 and 4.3.90.
+
+Two other vulnerabilities have been reported, and the mitigations
+for these are as follows:
+
+* Interleave-pivot
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 2978 / CVE-2016-1548
+ Affects: All ntp-4 releases.
+ CVSSv2: MED 6.4 - (AV:N/AC:L/Au:N/C:N/I:P/A:P)
+ CVSSv3: MED 7.2 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L
+ Summary: It is possible to change the time of an ntpd client or deny
+ service to an ntpd client by forcing it to change from basic
+ client/server mode to interleaved symmetric mode. An attacker
+ can spoof a packet from a legitimate ntpd server with an origin
+ timestamp that matches the peer->dst timestamp recorded for that
+ server. After making this switch, the client will reject all
+ future legitimate server responses. It is possible to force the
+ victim client to move time after the mode has been changed.
+ ntpq gives no indication that the mode has been switched.
+ Mitigation:
+ Implement BCP-38.
+ Upgrade to 4.2.8p7, or later, from the NTP Project Download Page
+ or the NTP Public Services Project Download Page. These
+ versions will not dynamically "flip" into interleave mode
+ unless configured to do so.
+ Properly monitor your ntpd instances.
+ Credit: This weakness was discovered by Miroslav Lichvar of RedHat
+ and separately by Jonathan Gardner of Cisco ASIG.
+
+* Sybil vulnerability: ephemeral association attack
+ Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
+ References: Sec 3012 / CVE-2016-1549
+ Affects: All ntp-4 releases up to, but not including 4.2.8p7, and
+ 4.3.0 up to, but not including 4.3.92
+ CVSSv2: LOW 3.5 - (AV:N/AC:M/Au:S/C:N/I:P/A:N)
+ CVSS3v: MED 5.3 - CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N
+ Summary: ntpd can be vulnerable to Sybil attacks. If one is not using
+ the feature introduced in ntp-4.2.8p6 allowing an optional 4th
+ field in the ntp.keys file to specify which IPs can serve time,
+ a malicious authenticated peer can create arbitrarily-many
+ ephemeral associations in order to win the clock selection of
+ ntpd and modify a victim's clock.
+ Mitigation:
+ Implement BCP-38.
+ Use the 4th field in the ntp.keys file to specify which IPs
+ can be time servers.
+ Properly monitor your ntpd instances.
+ Credit: This weakness was discovered by Matthew Van Gundy of Cisco ASIG.

+
+New option to 'configure':
+
+While looking in to the issues around Bug 2978, the "interleave pivot"
+issue, it became clear that there are some intricate and unresolved
+issues with interleave operations. We also realized that the interleave
+protocol was never added to the NTPv4 Standard, and it should have been.
+
+Interleave mode was first released in July of 2008, and can be engaged
+in two ways. Any 'peer' and 'broadcast' lines in the ntp.conf file may
+contain the 'xleave' option, which will expressly enable interlave mode
+for that association. Additionally, if a time packet arrives and is
+found inconsistent with normal protocol behavior but has certain
+characteristics that are compatible with interleave mode, NTP will
+dynamically switch to interleave mode. With sufficient knowledge, an
+attacker can send a crafted forged packet to an NTP instance that
+triggers only one side to enter interleaved mode.
+
+To prevent this attack until we can thoroughly document, describe,
+fix, and test the dynamic interleave mode, we've added a new
+'configure' option to the build process:
+
+ --enable-dynamic-interleave
+
+This option controls whether or not NTP will, if conditions are right,
+engage dynamic interleave mode. Dynamic interleave mode is disabled by
+default in ntp-4.2.8p7.

+
+The NTP project's github repository is at https://github.com/ntp-project/ntp.
+
+There are two branches, master and stable.
+
+The stable branch is the current supported production code branch, the
+ntp-stable code (even 2nd number).
+
+The master branch is for new development, also known as ntp-dev (which
+has an odd 2nd number).
+
+If you have some work you'd like to add, then if there is any interest
+in seeing that work in the current production release then base your work
+on the stable branch, and pull your work into a master copy to allow for
+publishing your changes in the ntp-dev or master branch.
+
+If there is no expectation that your work will be included in the
+current stable release (the ntp-stable code) then it's better to do your
+work on a copy of the master branch.
+
+Make sure that any changes you make to stable pull cleanly into master.
+
+It's possible that after pulling your changes from stable to master that
+some additional cleanup will be required in master. Please do this.
+
+If you follow this method, then if you submit a pull request for either
+master or for master+stable, it will be easy for us to evaluate and
+incorporate your work.
+
+Please also note that your submissions will be able to be evaluated and
+handled sooner if the repo that contains your pull requests also includes
+test cases.
+
+The general workflow is as follows:
+
+1) If you haven't, create a fork of ntp-project/ntp with your github account.
+ i) Log on to github.com with your github account.
+ - If you don't have one, create one first. (read: https://help.github.com/articles/signing-up-for-a-new-github-account)
+ - Make sure you also have a SSH key associated with your github account.
+ (read: https://help.github.com/articles/generating-ssh-keys/)
+ ii) Go to https://github.com/ntp-project/ntp
+ iii) On the top right corner, right below the header bar, there is
+ a button labeled "Fork". Click on it. This will fork the current
+ ntp master to your own account. Once done, it will go to your account's
+ version of the ntp repository. (Your fork of ntp source)
+ iv) Clone a local version of your fork.
+ - git clone git@github.com:/ntp
+
+2) Look through the bugs listed in the bug tracker: http://bugs.ntp.org/
+
+3) Once you've found a bug to work on:
+
+ i) Create a branch off your own master branch of your local fork.
+ (the can be any valid short string that will tell you
+ what you're working on)
+ - git checkout -b
+
+ ii) Start working on the bug.
+ iii) When you create changes in the source, it would help you to
+ keep track of your changes by committing to your local repo.
+ (This way, every small change is tracked and when you've
+ made a mistake, you can always go back.)
+ - git commit -a -m "description of change"
+ iv) Once you are satisfied, you can push to your github account's
+ repository.
+ - git push origin
+ v) (go to step iii).
+
+4) Once you feel you've fixed the bug (and tested it), you need to
+ create a pull request on your branch on github. (Read up on
+ pull requests @ https://help.github.com/articles/using-pull-requests)
+
+ i) Create your pullrequest by following the instructions @
+ https://help.github.com/articles/creating-a-pull-request/
+
+5) Your pull request will be reviewed by committers and when it
+ passes review, it will be merged by the reviewer/allowed committer.
+
+6) You have fixed a bug. Goto step #2.
+
+If these patches are for a bugzilla issue, mark the issue as Resolved/READY
+with a comment of "Please pick up the patches from XXX" where XXX is
+something like:

This library is available from http://www.openssl.org and can be installed using the procedures outlined in the Building and Installing the Distribution page. Once installed, the configure and build process automatically detects the library and links the library routines
required.
-In addition to the symmetric key algorithms, this distribution includes support for the Autokey public key algorithms and protocol specified in RFC-5906 "Network Time Protocol Version 4: Autokey Specification". This support is available only if the OpenSSL library has been installed and the --enable-autokey option is used when the distribution is built.
- Public key cryptography is generally considered more secure than symmetric key cryptography, since the security is based on private and public values which are generated by each participant and where the private value is never revealed. Autokey uses X.509 public certificates, which can be produced by commercial services, the OpenSSL application program, or the ntp-keygen utility program in the NTP software distribution.
-Note that according to US law, NTP binaries including OpenSSL library components, including the OpenSSL library itself, cannot be exported outside the US without license from the US Department of Commerce. Builders outside the US are advised to obtain the OpenSSL library directly from OpenSSL, which is outside the US, and build outside the US.
-Authentication is configured separately for each association using the key or autokey option of the server configuration command, as described in the Server Options page. The ntp-keygen page describes the files required for the various authentication schemes. Further details are in the briefings, papers and reports at the NTP project page linked from www.ntp.org.
-By default, the client sends non-authenticated packets and the server responds with non-authenticated packets. If the client sends authenticated packets, the server responds with authenticated packets if correct, or a crypto-NAK packet if not.. In the case of unsolicited packets which might consume significant resources, such as broadcast or symmetric mode packets, , authentication is required, unless overridden by a disable auth command. In the current climate of targeted broadcast or "letterbomb" attacks, defeating this requirement would be decidedly dangerous. In any case, the notrust flag, described on the Access Control Options page, can be used to disable access to all but correctly authenticated clients..

Symmetric Key Cryptography
-The original NTPv3 specification (RFC-1305), as well as the current NTPv4 specification (RFC-5905), allows any one of possibly 65,534 message digest keys (excluding zero), each distinguished by a 32-bit key ID, to authenticate an association. The servers and clients involved must agree on the key ID, key type and key to authenticate NTP packets.
-The message digest is a cryptographic hash computed by an algorithm such as MD5 or SHA. When authentication is specified, a message authentication code (MAC) is appended to the NTP packet header. The MAC consists of a 32-bit key identifier (key ID) followed by a 128- or 160-bit message digest. The algorithm computes the digest as the hash of a 128- or 160- bit message digest key concatenated with the NTP packet header fields with the exception of the MAC. On transmit, the message digest is computed and inserted in the MAC. On receive, the message digest is computed and compared with the MAC. The packet is accepted only if the two MACs are identical. If a discrepancy is found by the client, the client ignores the packet, but raises an alarm. If this happens at the server, the server returns a special message called a crypto-NAK. Since the crypto-NAK is protected by the loopback test, an intruder cannot disrupt the protocol by sending a bogus crypto-NAK.
-Keys and related information are specified in a keys file, which must be distributed and stored using secure means beyond the scope of the NTP protocol itself. Besides the keys used for ordinary NTP associations, additional keys can be used as passwords for the ntpq and ntpdc utility programs. Ordinarily, the ntp.keys file is generated by the ntp-keygen program, but it can be constructed and edited using an ordinary text editor.
- Each line of the keys file consists of three fields: a key ID in the range 1 to 65,534, inclusive, a key type, and a message digest key consisting of a printable ASCII string less than 40 characters, or a 40-character hex digit string. If the OpenSSL library is installed, the key type can be any message digest algorithm supported by the library. If the OpenSSL library is not installed, the only permitted key type is MD5.
+The original NTPv3 specification (RFC-1305), as well as the current NTPv4 specification (RFC-5905), allows any one of possibly 65,534 message digest keys (excluding zero), each distinguished by a 32-bit key ID, to authenticate an association. The servers and clients involved must agree on the key ID, key type and key to authenticate NTP packets.
+The message digest is a cryptographic hash computed by an algorithm such as MD5 or SHA. When authentication is specified, a message authentication code (MAC) is appended to the NTP packet header. The MAC consists of a 32-bit key identifier (key ID) followed by a 128- or 160-bit message digest. The algorithm computes the digest as the hash of a 128- or 160- bit message digest key concatenated with the NTP packet header fields with the exception of the MAC. On transmit, the message digest is computed and inserted in the MAC. On receive, the message digest is computed and compared with the MAC. The packet is accepted only if the two MACs are identical. If a discrepancy is found by the client, the client ignores the packet, but raises an alarm. If this happens at the server, the server returns a special message called a crypto-NAK. Since the crypto-NAK is protected by the loopback test, an intruder cannot disrupt the protocol by sending a bogus crypto-NAK.
+Keys and related information are specified in a keys file, which must be distributed and stored using secure means beyond the scope of the NTP protocol itself. Besides the keys used for ordinary NTP associations, additional keys can be used as passwords for the ntpq and ntpdc utility programs. Ordinarily, the ntp.keys file is generated by the ntp-keygen program, but it can be constructed and edited using an ordinary text editor.
+ Each line of the keys file consists of three or four fields: a key ID in the range 1 to 65,534, inclusive, a key type, a message digest key consisting of a printable ASCII string less than 40 characters or a 40-character hex digit string, and an optional comma-separated list of IPs that are allowed to serve time. If the OpenSSL library is installed, the key type can be any message digest algorithm supported by the library. If the OpenSSL library is not installed, the only permitted key type is MD5.

Figure 1. Typical Symmetric Key File
-Figure 1 shows a typical keys file used by the reference implementation when the OpenSSL library is installed. In this figure, for key IDs in he range 1-10, the key is interpreted as a printable ASCII string. For key IDs in the range 11-20, the key is a 40-character hex digit string. The key is truncated or zero-filled internally to either 128 or 160 bits, depending on the key type. The line can be edited later or new lines can be added to change any field. The key can be change to a password, such as 2late4Me for key ID 10. Note that two or more keys files can be combined in any order as long as the key IDs are distinct.
-When ntpd is started, it reads the keys file specified by the keys command and installs the keys in the key cache. However, individual keys must be activated with the trustedkey configuration command before use. This allows, for instance, the installation of possibly several batches of keys and then activating a key remotely using ntpq or ntpdc. The requestkey command selects the key ID used as the password for the ntpdc utility, while the controlkey command selects the key ID used as the password for the ntpq utility.

Microsoft Windows Authentication
-In addition to the above means, ntpd now supports Microsoft Windows MS-SNTP authentication using Active Directory services. This support was contributed by the Samba Team and is still in development. It is enabled using the mssntp flag of the restrict command described on the Access Control Options page. Note: Potential users should be aware that these services involve a TCP connection to another process that could potentially block, denying services to other users. Therefore, this flag should be used only for a dedicated server with no clients other than MS-SNTP.

-In the protocol described in the NTP specification and reference implementation up to now, the transmit timestamp, which is captured before the message digest is computed and the packet queued for output, is properly called as a softstamp The receive timestamp, which is captured after the input driver interrupt routine and before the packet is queued for input, is properly called a drivestamp. For enhanced accuracy it is desirable to capture the transmit timestamp as close to the wire as possible; for example, after the output driver interrupt routine.
- In other words, we would like to replace the transmit softstamp with a drivestamp, but the problem is the transmit drivestamp is available only after the packet has been sent. A solution for this problem is the two-step or interleaved protocol described on this page and included in the the current reference implementation. In interleaved modes the transmit drivestamp for one packet is actually carried in the immediately following packet. The trick, however, is to implement the interleaved protocol without changing the NTP packet header format, without compromising backwards compatibility and without compromising the error recovery properties.
- The reference implementation captures a softstamp before the message digest routine and a drivestamp after the output interrupt routine. In this design the latter timestamp can be considered most accurate, as it avoids the various queuing and transmission latencies. The difference between the two timestamps, which is called the interleaved or output delay, varies from 16 μs for a dual-core Pentium running FreeBSD 6.1 to 1100 μs for a Sun Blade 1500 running Solaris 10.
