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

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

90 check_ping times out 1 second quicker if host is unreachable

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