	* Makefile.PL, MANIFEST, ...: Packaging improvements

2022-11-23  Simon Leinen  <simon.leinen@switch.ch>

	* test/get-cisco-power-usage.pl: New demo script

2017-06-24  Allan Jude  <allanjude@freebsd.org>

	* lib/SNMP_Session.pm: Apply Socket6 patch from FreeBSD ports

2008-03-19  Simon Leinen  <simon.leinen@switch.ch>

	* lib/SNMP_Session.pm: Improved initialization of the flags for
	non-blocking behavior in receive_response_3().  The __DIE__ and
	__WARN__ signal handlers should be bound to the defaults, because
	the caller might be binding those and get in our way.  Also, we
	only want to compute the flags once, on initialization.

2007-12-22  Simon Leinen  <simon.leinen@switch.ch>

2007-05-03  Simon Leinen  <simon.leinen@switch.ch>

	* lib/SNMP_Session.pm: Added Mike Fischer as a contributor.

	($VERSION): Incremented to 1.10.

	(receive_response_3): Added optional "dont_block" argument.  If
	this is present and non-zero, pass MSG_DONTWAIT to the recv()
	call.  MSG_DONTWAIT is wrapped in an eval, to avoid breaking the
	code on systems that don't have the flag.

	(request_response_5): Pass dont_block=1 to receive_response_3.
	According to Mike Fisher, Linux sometimes blocks on recv() even
	though a select() for readability has returned, for example when a
	checksum fails.

	for `hostname' command.  Caches the result so that files are only
	opened once.

	(print_physical): Use new forms of per-router defaults.

	* test/entls:
	Changed so that `-t' generates a Cricket configuration file to measure
	all transceivers that support DOM (Digital Optical Monitoring).  This
	involves some structural changes.

	(print_phys_tree): Implemented in terms of the new
	`print_phys_tree_1'.

	(print_phys_tree_1): Maintain a stack of parent nodes when traversing
	the node tree.  This stack is stored in each node's `parent_stack'
	slot, and can be used by the node class' `tostring' method.

	* test/entls ($print_vendor_type, $print_ent_physical_index):
	New variables.

	and up, using Net::SNMP.

	* lib/SNMP_util.pm (snmpLoad_OID_Cache):

	value.  This allows us to read SunNet Manager OID files, which are
	also distributed by e.g. Cisco (ftp://ftp.cisco.com/pub/mibs/oid).
	Idea by Jan van Keulen, code cleanup by Mike Mitchell.

2006-07-13  Simon Leinen  <simon.leinen@switch.ch>

	* lib/SNMP_Session.pm ($VERSION): Incremented to 1.08.

	(open_trap_session): Use `undef' rather than 0.0.0.0 as the remote
	address in the SNMP_Session structure.

	(receive_response_3): Changed handling of mismatched source
	addresses.  If the source address of an incoming packet doesn't match
	the expected address (as specified by the session's `remote_addr'
	slot), the PDU is always ignored and zero is returned.  Also, if the
	$recycle_socket variable is set, mismatched replies never cause a
	warning even when the session's `debug' slot is set.

	object is NOT set.

2000-10-02  simon  <simon.leinen@switch.ch>

	* test/walk-test.pl:
	Don't ask for ipAdEntAddr in map_table because that can be derived
	from the index.

2000-09-24  Simon Leinen  <simon.leinen@switch.ch>

	* test/max-list-sessions: Added header comment.

	* test/max-list-sessions (out_session, out_call): Removed.

	* MANIFEST (test/asn1-test.pl):
	Removed because it refers to the ASN_1.pm module,
	which I started writing three years ago but never finished, and which
	is (correctly) not included in the distribution.

2000-05-03  Simon Leinen  <simon.leinen@switch.ch>

	* test/if-counters.pl: Added `-D' option to show drops (ifOutDiscards).

	Be more modular with respect to printing/reading the different
	optional columns.

2000-04-12  Simon Leinen  <simon.leinen@switch.ch>
