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
6 New check_icmp -s option to specify the source IP address
7 check_dns now sorts addresses for testing results for more than one returned IP (Matthias Urlichs)
8 Fix segfault in check_ntp_time and (deprecated) check_ntp. (Bug #1862300)
10 1.4.11 13th December 2007
11 Fixed check_http regression in 1.4.10 where following redirects to
12 relative URLs on virtual hosts failed if both "-H" and "-I" were used
13 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
14 You should read the --help output so see which one is suitable for you. check_ntp_peer
15 implement stratum thresholds support (feature request #1703823).
16 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
17 as long as the thresholds range include -1. If no offset threshold is specified
18 and the offset is unavailable, will return UNKNOWN as well.
19 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
20 is "-1" as the default range starts at 0. See Examples in --help output.
21 Fixed broken usage2 in check_snmp and check_cluster
22 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
23 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
24 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
25 Fixed check_load argument handling when not passing triplets (bug #1831890)
26 Fixed buffer overflow in check_snmp (CVE-2007-5623)
27 Tinderbox builds now runs tests in a verbose mode
28 Updated Nagios::Plugin to 0.22
29 VPATH problem fixed for compiling plugins-root
31 1.4.10 28th September 2007
32 Fix check_http buffer overflow vulnerability when following HTTP redirects
33 check_http now explicitly asks HTTP/1.1 servers to close the connection
34 after completion of the response
35 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
36 is now deprecated. See --help for further information.
37 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
38 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
39 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
40 Thus accessibility of remote filesystems can be checked without any threshold comparison.
41 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
42 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
43 New check_disk -A option to select all filesystems explicitly
44 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
45 Passing -E after -p or -r results in UNKNOWN state, now
46 This is needed due to the new ignore feature
47 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
48 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
49 to check DHCP servers on remote networks
50 New check_dhcp -m/--mac option which allows for specifying the MAC
51 address to use in the DHCP request
52 The check_dhcp -r and -s options now accept host names, too
53 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
54 Fix check_smtp's handling of multiple-packet server responses
55 WARNING: Fix for negate which may break existing commands:
56 - stop evaluating command line options through shell twice
57 - enforce a full path for the command to run
58 The "negate" utility can now remap custom states
59 Check_radius now supports radiusclient-ng
60 The (undocumented) positional parameter parsing which check_radius used
61 instead of getopt(3) if 8 arguments were given is no longer available
62 Check_by_ssh now supports multiline output
63 IPv6 support can now be disabled using ./configure --without-ipv6
64 Fix check_ntp now honor ntp flags
66 1.4.9 4th June 2006
67 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
68 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
69 check_snmp now supports Counter64
70 Fix compilation of check_ldap, check_radius and check_pgsql

72 Fix check_time returning wrong OK when time is before the epoch on some arch
73 Make check_http output more consistent
74 Fix possible check_http segfaults when following HTTP redirects
75 check_snmp don't warn anymore if something is printed on stderr
76 Fix check_tcp segfault when multiple expect strings are given
77 New option for check_tcp: -A/--all to test if all given expect strings match

121 check_udp2 removed. check_udp is now linked to check_tcp.c
122 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
123 as if mailqs were okay when the nagios user could not query the mail-queues
124 Compile problems with check_snmp fixed
126 1.4.3
127 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
