CLI Tools¶
bin/gnng
- Added flags to include un-numbered (-u) or disabled (-d) interfaces.
trigger.acl¶
- Minimal changes to support writing Dell ACLs
- Parser modifications to support negation of address objects in Junos ACLs. (Note that this relies on marking up ACLs with ‘trigger: make discard’ in term comments. This is undocmented functionality, currently used internally within AOL, and this code will only be used for Junos output.)
- [Feature] #47: Add parsing of ranges for
fragment-offset
in Juniper ACLs
trigger.changemgmt¶
- Refactored
BounceWindow
definition syntax to be truly usable by humans.
trigger.cmds¶
NetACLInfo
andbin/gnng
can now include disabled or un-addressed interfaces in their results.- Added
pyparsing
as a hard requirement until further notice so thatNetACLInfo
andbin/gnng
will behave as expected without confusing developers and users alike. - You may now pass login credentials to
Commando
using thecreds
argument.
trigger.tacacsrc¶
- Added a utility function
validate_credentials()
to ... validate credentials ... and return aCredentials
object.
trigger.twister¶

- [Feature] #56: You may now optionally run “commit full” on Juniper
devices. (See
JUNIPER_FULL_COMMIT_FIELDS
for more information) - Added support for sending an enable password to IOS-like devices
when an enable prompt is detected.
- This can either be provided in your netdevices metadata by
populating the
enablePW
attribute, or by setting the environment variableTRIGGER_ENABLEPW
to the value of the enable password.
- This can either be provided in your netdevices metadata by
populating the
- Added error-detection for Brocade MLX routers.
Tacacrc()
is now only called once when creds aren’t provided upon creation of new clients.
trigger.utils¶
- New utility module
xmltodict
for convert XML into dictionaries, primarily so such objects can be serialized into JSON.

1.3.0¶
Warning
If you are upgrading from Trigger Before Upgrading from Trigger 1.2 or earlier, please heed these steps!
- Add
NETDEVICES_SOURCE = NETDEVICES_FILE
to yoursettings.py
. This variable has replacedNETDEVICES_FILE
. - Create your Bounce window mappings in
bounce.py
and put it in/etc/trigger/bounce.py
. Seeconf/bounce.py
in the source distribution for an example.
General changes
- All references to psyco have been removed as it doesn’t support 64-bit and was causing problems in Python 2.7.3.
- A new document, Adding New Vendors to Trigger, has been added to use as checklist for adding new vendor support to Trigger.
- Added Allan Feid as contributor for his crazed ideas.
[Feature] #10: The following changes have been made within
changemgmt
, which provides Trigger’s support for bounce windows and timezones, to move the bounce window settings into configurable data vs. static in the module code.- This module has been convertd into a package.
- The Bounce window API has been totally overhauled. Bounce windows are no
longer hard-coded in
changemgmt
and are now configured usingbounce.py
and specified usingBOUNCE_FILE
. The interface for creatingBounceWindow
objects was greatly simplified to improve readability and usage.
- Added sample
bounce.py
toconf/bounce.py
in the Trigger source distribution. - New setting variables in
settings.py
:BOUNCE_FILE
- The location of the bounce window mapping definitions. Defaults to/etc/trigger/bounce.py
.BOUNCE_DEFAULT_TZ
- Default timezone for bounce windows. Defaults to'US/Eastern'
.BOUNCE_DEFAULT_COLOR
- The default bounce risk-level status color. Defaults to'red'
.
[Feature] #55: The following changes have been made within
netdevices
to make it easier to populateNetDevices
from arbitrary sources by implementing pluggable loaders.- This module has been converted into a package.
- All hard-coded metadata parsing functions and associated imports have been replaced with loader plugin classes. Filesystem loaders provided by default for JSON, XML, Sqlite, Rancid, and new: CSV!). The bare minimum config for CSV is a newline-separated CSV file populated with “hostname,vendor”
- New configuration setting:
NETDEVICES_LOADERS
used to define a list of custom loader classes to try in turn. The first one to return data wins. - The configuration settings
SUPPORTED_FORMATS
andNETDEVICES_FORMAT
have been deprecated. - The configuration setting
NETDEVICES_SOURCE
has replacedNETDEVICES_FILE
. - The sample
settings.py
(found atconf/trigger_settings.py
in the source distribution) illustrates how one may useNETDEVICES_SOURCE
andNETDEVICES_LOADERS
to replace the deprecated settingsNETDEVICES_FORMAT
andNETDEVICES_FILE
.
The following changes have been made within
twister
, which provides Trigger’s remote execution functionality:- [Feature] #22: Added Aruba wireless controller and Brocade ADX/VDX support
for execute/pty in trigger.twister and any device that requires pty-req and
shell without actualling using a pty. The channel class for this
functionality is called
TriggerSSHAsyncPtyChannel
- Added a new
requires_async_pty
attribute toNetDevice
objects to help identify devices that require such channels. - Added a
force_cli
flag toexecute()
to force CLI execution on Juniper devices instead of Junoscript. - The default client factory (
TriggerClientFactory
) now callsvalidate_credentials()
instead of directly instantiatingTacacsrc
anytime credentials are populated automatically, resulting in only a single call toTacacsrc()
, when creds aren’t provided. - Added error-detection for Brocade MLX devices.
- [Feature] #22: Added Aruba wireless controller and Brocade ADX/VDX support
for execute/pty in trigger.twister and any device that requires pty-req and
shell without actualling using a pty. The channel class for this
functionality is called
The following changes have been made within
cmds
, which provides an extensible, developer-friendly interface to writing command exeuction adapters:- Added a
force_cli
flag toCommando
constructor to force CLI execution on Juniper devices instead of Junoscript. - The
timeout
value may now be set as a class variable inCommando
subclasses. Commando
now steps throughcommands
as iterables instead of assuming they are lists. The iterable is also now explicitly cast to a list when we need it be one.- A minor bugfix in
Commando
causing results from multiple Commando instances to collide with each other because they were inheriting an empty results{}
from the class object. Commando
now acceptscreds
as an optional argument. If not set, it will default to reading user credentials from.tacacsrc
.
- Added a
The following changes have been madw within
parser
, which provides Trigger’s support for parsing network access control lists (ACLs) and firewall policies.- [Feature] #12: Support has been added for parsing IPv6 addresses in Juniper firewall filters. (This does not include full IPv6 firewall support!)
- [Bug] #26: The ACL parers was modified to support negation of addresses
using the syntax
{ip} except;
in Juniper firewall filters. To facilitate this a custom IP address class was created:TIP
(which is a subclass ofIPy.IP
). - The prefix on /32 and /128 IPs in Juniper ACLs is now always displayed.
The following changes have been made within
tacacsrc
, which provides functionality to cache and retrieve user credentials:- Added a new function
validate_credentials()
to (you guessed it!) validate credentials. It supports input in the form 2-tuples (username, password), 3-tuples (username, password, realm), and dictionaries of the same and returns aCredentials
object.
- Added a new function
The following changes have been made to Trigger’s command-line utilities:
- [Feature] #60:
bin/load_acl
will now shutdown gracefully if initial the MySQL connection fails, using a try..except to display some information about the connection failure without a traceback. For other MySQL issues, we will leave as is (dumping the traceback) because they would represent coding or transient issues, and we should present as much information as we have. - [Feature] #20:
bin/gnng
(get_nets) In support of displaying Juniper ‘sp’ interfaces (which are un-numbered and were being skipped for this reason), we’ve added flags to include un-numbered (-u
) or disabled (-d
) interfaces for any device platform.
- [Feature] #60:
1.2.4¶
- The commands required to commit/save the configuration on a device are now
attached to
NetDevice
objects under thecommit_commands
attribute, to make it easier to execute these commands without having to determine them for yourself. - [Feature] #56: Added a way to optionally perform a
commit full
operation on Juniper devices by defining a dictionary of attributes and values for matching devices usingJUNIPER_FULL_COMMIT_FIELDS
. This modifies thecommit_commands
that are assigned when theNetDevice
object is created. - [Bug] #33: Console paging is now disabled by default for async SSH channels.
1.2.3¶
- [Feature] #47: Added parsing of ranges for
fragment-offset
statements in Juniper ACLs. - [Bug] #49: Changed ACL parser to omit src/dst ports if port range is
0-65535
. - [Bug] #50: Fix typo that was causing Cisco parsing to generate an unhandled
exception within
NetACLInfo
. - Minor bugfix when checking device names and printing a warning within
Commando
. - Updated docs to say we’re using a interactive Python interpreter and added OpenHatch profile to contact info.
1.2.2¶
- [Feature] #16: Arista support was added to
bin/load_acl
- [Bug] #45: Added “SSH-1.99” as a valid SSHv2 version in
test_ssh()
to fix a bug in which devices presenting this banner were errantly falling back to telnet and causing weird behavior during interactive sessions. - [Feature] #46: Changed
connect()
to pass the vendor name toget_init_commands()
so that it is more explicit when debugging. - [Feature] #29: Added an extensible event notification system
- A new pluggable notification system has been added in
notifications
, which defaults to email notifications. New event handlers and event types can be easily added and specified with the configuration usingNOTIFICATION_HANDLERS
. - The following changes have been made to
bin/load_acl
:- All alerts are now using the new notification system
email_users()
moved tosend_email()
- All calls to send failures now call
send_notification()
- All calls to send successes now calls
send_email()
- In support of the new notification system, the following config
settings have been added:
EMAIL_SENDER
- The default email senderNOTIFICATION_SENDER
- The default notification senderSUCCESS_RECIPIENTS
- Hosts/addresses to send successesFAILURE_RECIPIENTS
- Hosts/addresses to send failuresNOTIFICATION_HANDLERS
- A list of handler functions to process in order
- A new utility module has been added to import modules in
importlib
, andtrigger.conf.import_path()
was moved toimport_module_from_path()
to bring these import tools under one roof.
- A new pluggable notification system has been added in
1.2.1¶
- [Bug] #30: Bugfix in
bin/acl
where tftproot was hard-coded. It now reads fromTFTPROOT_DIR
. - [Feature] #37: Fixed misleading “make discard” output from
bin/check_access
, to use theTerm.extra
attribute to store a user-friendly comment to make it clear that the term’s action has been modified by the “make discard” keyword. - [Feature] #39: Call
create_cm_ticket()
in atry..commit
block so it can’t crashbin/load_acl
. - [Bug] #40: Update dot_gorc.example with
[init_commands]
. - [Bug] #43: Bugfix in bin/acl to address incorrect exception reference from when exceptions were cleaned up in release 1.2.
- Simplified basic
Commando
example indocs/index.rst
. - Simplified activity output in
Commando
base to/from methods - Replaced all calls to
time.sleep()
withreactor.callLater()
withintwister
support of thecommand_interval
argument to Twisted state machine constructors. - Added a way to do SSH version detection within
network
- Enhanced
test_tcp_port()
to support optionalcheck_result
andexpected_result
arguments. Ifcheck_result
is set, the first line of output is retreived from the connection and the starting characters must matchexpected_result
. - Added a
test_ssh()
function to shortcut to check port 22 for a banner. Defaults to SSHv2. - SSH auto-detection in
NetDevices
objects now usestest_ssh()
.

- Added a new
crypt_md5()
password-hashing function. - Added proper argument signature to
get_netdevices
. - Updated misnamed
BadPolicerNameError
toBadPolicerName

bin/acl_script
.
1.2¶
- [Feature] #23: Commando API overhauled and support added for RANCID
- RANCID is now officially supported as a source for network device
metadata. A new RANCID compatibility module has been added at
rancid
, with support for either single or multiple instance configurations. Multiple instances support can be toggled by settingRANCID_RECURSE_SUBDIRS
toTrue
. - The following changes have been made to
netdevices
:NetDevices
can now import from RANCID- A new
Vendor
type has been added tonetdevices
to store canonical vendor names as determined by the new settingVENDOR_MAP
. - When
NetDevice
objects are created, the manufacturer attribute is mapped to a dynamic vendor attribute. This is intended to normalize the way that Trigger identifies vendors internally by a single lower-cased word. - All
NetDevice
objects now have avendor
attribute with their canonicalVendor
object attached to it. - If the
deviceType
attribute is not set, it is determined automatically based on thevendor
attribute. The default types for each vendor can be customized usingDEFAULT_TYPES
. If a vendor is not specified witihinDEFAULT_TYPES
,FALLBACK_TYPE
. will be used. - All logical comparisons that onced used the hard-coded value of the
manufacturer
attribute of a device now instead compare against thevendor
attribute. - You may now tell NetDevices not to fetch acls from AclsDB when instantiate you may also do the same for individual NetDevice objects that you manually create
- The following changes have been made to
cmds
:- The
Commando
class been completely redesigned to reduce boilerplate and simplify creation of new command adapters. This is leveraging the changes toNetDevice
objects, where the vendor name can be expected to always be normalized to a single, lower-cased word. Defining commands to send to devices is as simple as definiing ato_{vendor}
method, and parsing return results as simple asfrom_{vendor}
. - All dynamic method lookups are using the normalized vendor name (e.g. cisco, juniper).
- Base parse/generate lookup can be disabled explicitly in
Commando
subclasses or as an argument to the constructor. NetACLInfo
adapted to use Commando 2.0
- The
- The following changes have been made to Trigger’s exception handling
- All exceptions moved to
exceptions
and given docstrings trigger.acl.exceptions
has been removed- All calls to exceptions updated to new-style exceptions
- All exceptions moved to
- A new -v option has been added to
bin/netdev
to support vendor lookups
- RANCID is now officially supported as a source for network device
metadata. A new RANCID compatibility module has been added at
- [Feature] #4: Support for SSH auto-detection and pty/async improvements:
- The following changes have been made to
twister
:- Detection of remotely closed SSH connections so
bin/gong
users can be properly notified (e.g. ssh_exchange_identification errors) - New
execute
function to automatically choose the bestexecute_
function for a givenNetDevice
object, and is now attached to allNetDevice
objects execute_ioslike
now determines whether to use SSH or Telnet automatically- All pty connection logic moved out of
bin/gong
intotwister
and is exposed as theconnect
function and also attached to allNetDevice
objects - Interactive sessions may now be optionally logged to a file-like object by
passing the log_to argument to the
Interactor
constructor execute_junoscript
now usingexecute_generic_ssh
- Command interval added to Junoscript channels for consistency
- Global
NetDevices
import removed from twister; moved to only occur when a telnet channel is created
- Detection of remotely closed SSH connections so
- The following changes have been made to
netdevices
:- All
NetDevice
objects now have aexecute
method to perform async interaction - The
connect
function is now automatically attached to everyNetDevice
object; to get a pty it’s as simple asdev.connect()
. - New helper methods added to
NetDevice
objects:- SSH functionality methods:
has_ssh()
(port connection test),can_ssh_async()
(device supports async),can_ssh_pty()
(device supports pty) is_ioslike()
to test if a device is IOS-like as specified byIOSLIKE_VENDORS
.is_netscreen
to test if a device is a NetScreen firewallis_reachable
to test if a device responds to a ping
- SSH functionality methods:
- All
- The following changes have been made to
settings
:- A mapping of officially supported platforms has been defined at
SUPPORTED_PLATFORMS
VALID_VENDORS
has been renamed toSUPPORTED_VENDORS
- A mapping of officially supported device types has been defined at
SUPPORTED_TYPES
- You may now disable telnet fallback by toggling
TELNET_ENABLED
- You may now disable SSH for pty or async by vendor/type using
SSH_PTY_DISABLED
andSSH_ASYNC_DISABLED
respectively SSH_TYPES
has been removed as it is no longer needed
- A mapping of officially supported platforms has been defined at
Commando
experimentally using the newNetDevice.execute()
method- Two new helper functions added to
cli
:setup_tty_for_pty
andupdate_password_and_reconnect
, which modularize functionality that was in bin/gong that didn’t seem to fit anywhere else
- The following changes have been made to
- [Feature] #21: The following changes have been made to support A10 hardware
and to enhance handling of SSH channels:
- Added a new generic SSH channel. The NetScreen and A10 channels are based from this. Further abstraction needed to roll NetScaler channel into this as well.
- Added a new
execute_generic_ssh
factory function. - Refactored
execute_netscreen
to useexecute_generic_ssh
- Added a new
execute_ioslike_ssh
factory function utilizing the generic SSH channel to support SSH on IOS-like devices (Brocade, Cisco, Arista, A10, etc.). Works like a charm except for the Brocade VDX. - The
Commando
was updated to support A10, NetScreen. Brocade, Arista changed to use SSH vs. telnet. - All prompt-matching patterns moved to top of
trigger.twister
as constants - A10 added to
IOSLIKE_VENDORS
- [Feature] #24:
bin/gong
will now display the reason when it fails to connect to a device.

conf
converted from a module to a package.- All global default settings are now baked into trigger.conf.settings
settings
andautoacl
may now be imported without the proper expected config files in place on disk. If the config files cannot be found, default versions of these objects will be returned.- All trigger modules can now be imported with default values (but don’t try instantiating any objects without following the install instructions!)
- [Bug] #2: Fixed a bug in
Tacacsrc
where newly-created .tacacsrc files were world-readable. Correct 0600 perms are now enforced on every write(). - [Feature] #3: Added the ability for :class:~trigger.twister.IoslikeSendExpect` to handle confirmation prompts (such as when a device asks you “are you sure? [y/N]:” by detecting common cases within the prompt-matching logic.
- [Feature] #5: Added ability for gong –oob to lookup devices by partial
hostnames using

- Typo fix in sample conf/trigger_settings.py
- Explicit imports from trigger.acl and a little docstring cleanup in bin/optimizer
- trigger.acl.autoacl.autoacl() now takes optional explicit_acls as 2nd argument, a set of ACL names, so that we can reference explicit_acls within autoacl() implicit ACL logic, but we don’t have to rely on the internals.
- trigger.acl.db.AclsDB.get_acl_set() modified to populate explicit_acls before implicit_acls. autoacl() is now called with these explicit_acls as the 2nd argument.
- Sample autoacl.py in conf/autoacl.py updated to support explicit_acls and a simple example of how it could be used.
- Added support for Juniper “family inet” filters in trigger.acl.parser.
