1 This file documents the major additions and syntax changes between releases.
3 1.4.12 or 1.5 ??
4 Added ./check_nt -v INSTANCES to count number of instances (Alessandro Ren)
6 1.4.11 13th December 2007
7 Fixed check_http regression in 1.4.10 where following redirects to
8 relative URLs on virtual hosts failed if both "-H" and "-I" were used
9 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
10 You should read the --help output so see which one is suitable for you. check_ntp_peer
11 implement stratum thresholds support (feature request #1703823).
12 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
13 as long as the thresholds range include -1. If no offset threshold is specified
14 and the offset is unavailable, will return UNKNOWN as well.
15 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
16 is "-1" as the default range starts at 0. See Examples in --help output.
17 Fixed broken usage2 in check_snmp and check_cluster
18 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
19 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
20 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
21 Fixed check_load argument handling when not passing triplets (bug #1831890)
22 Fixed buffer overflow in check_snmp (CVE-2007-5623)
23 Tinderbox builds now runs tests in a verbose mode
24 Updated Nagios::Plugin to 0.22
25 VPATH problem fixed for compiling plugins-root
27 1.4.10 28th September 2007
28 Fix check_http buffer overflow vulnerability when following HTTP redirects
29 check_http now explicitly asks HTTP/1.1 servers to close the connection
30 after completion of the response
31 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
32 is now deprecated. See --help for further information.
33 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
34 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
35 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
36 Thus accessibility of remote filesystems can be checked without any threshold comparison.
37 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
38 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
39 New check_disk -A option to select all filesystems explicitly
40 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
41 Passing -E after -p or -r results in UNKNOWN state, now
42 This is needed due to the new ignore feature
43 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
44 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
45 to check DHCP servers on remote networks
46 New check_dhcp -m/--mac option which allows for specifying the MAC
47 address to use in the DHCP request
48 The check_dhcp -r and -s options now accept host names, too
49 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
50 Fix check_smtp's handling of multiple-packet server responses
51 WARNING: Fix for negate which may break existing commands:
52 - stop evaluating command line options through shell twice
53 - enforce a full path for the command to run
54 The "negate" utility can now remap custom states
55 Check_radius now supports radiusclient-ng
56 The (undocumented) positional parameter parsing which check_radius used
57 instead of getopt(3) if 8 arguments were given is no longer available
58 Check_by_ssh now supports multiline output
59 IPv6 support can now be disabled using ./configure --without-ipv6
60 Fix check_ntp now honor ntp flags
62 1.4.9 4th June 2006
63 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
64 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
65 check_snmp now supports Counter64
66 Fix compilation of check_ldap, check_radius and check_pgsql
67 check_load can optionally divide by number of cpus
68 Fix check_time returning wrong OK when time is before the epoch on some arch
69 Make check_http output more consistent
70 Fix possible check_http segfaults when following HTTP redirects
71 check_snmp don't warn anymore if something is printed on stderr
72 Fix check_tcp segfault when multiple expect strings are given
73 New option for check_tcp: -A/--all to test if all given expect strings match
75 1.4.8 11th April 2007
76 Respects --without-world-permissions for setuid plugins
77 check_disk extra options for regex matching of filesystems and grouping of filesystems
78 for collective thresholds
79 Better configure test for mysqlclient availability
80 Various check_ntp fixes
82 1.4.7 29th March 2007
83 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
84 Fixed MKINSTALLDIRS problem in po/

86 Fixed broken HELO in check_smtp
87 check_icmp now allows to set a minimum number of hosts required for successs (-m)

89 check_ping times out 1 second quicker if host is unreachable
90 Root plugins installed with world executable
91 check_sybase from contrib now maintained in NagiosExchange
92 --with-nagios-user/group reinstated ./configure option

117 check_udp2 removed. check_udp is now linked to check_tcp.c
118 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
119 as if mailqs were okay when the nagios user could not query the mail-queues
120 Compile problems with check_snmp fixed
122 1.4.3
123 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
