1 This file documents the major additions and syntax changes between releases.
4 Fix check_http regression in 1.4.10 where following redirects to
5 relative URLs on virtual hosts failed if both "-H" and "-I" were used
6 Add stratum thresholds support to check_ntp (feature request #1703823)
7 check_ntp now return UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
8 as long as the thresholds range inculde -1. If no offset threshold is specified
9 and the offset is unavailable, will return UNKNOWN as well.
10 NOTE: If jitter thresholds are specified integers it will return CRITICAL if jitter
11 is "-1" as the default range starts at 0. See Examples in --help output.
13 1.4.10 28th September 2007
14 Fix check_http buffer overflow vulnerability when following HTTP redirects
15 check_http now explicitly asks HTTP/1.1 servers to close the connection
16 after completion of the response
17 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
18 is now deprecated. See --help for further information.
19 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
20 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
21 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
22 Thus accessibility of remote filesystems can be checked without any threshold comparison.
23 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
24 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
25 New check_disk -A option to select all filesystems explicitly
26 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
27 Passing -E after -p or -r results in UNKNOWN state, now
28 This is needed due to the new ignore feature
29 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
30 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
31 to check DHCP servers on remote networks
32 New check_dhcp -m/--mac option which allows for specifying the MAC
33 address to use in the DHCP request
34 The check_dhcp -r and -s options now accept host names, too
35 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
36 Fix check_smtp's handling of multiple-packet server responses
37 WARNING: Fix for negate which may break existing commands:
38 - stop evaluating command line options through shell twice
39 - enforce a full path for the command to run
40 The "negate" utility can now remap custom states
41 Check_radius now supports radiusclient-ng
42 The (undocumented) positional parameter parsing which check_radius used
43 instead of getopt(3) if 8 arguments were given is no longer available
44 Check_by_ssh now supports multiline output
45 IPv6 support can now be disabled using ./configure --without-ipv6
46 Fix check_ntp now honor ntp flags
49 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
50 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
51 check_snmp now supports Counter64
52 Fix compilation of check_ldap, check_radius and check_pgsql
53 check_load can optionally divide by number of cpus
54 Fix check_time returning wrong OK when time is before the epoch on some arch
55 Make check_http output more consistent
56 Fix possible check_http segfaults when following HTTP redirects
57 check_snmp don't warn anymore if something is printed on stderr
58 Fix check_tcp segfault when multiple expect strings are given
59 New option for check_tcp: -A/--all to test if all given expect strings match
62 Respects --without-world-permissions for setuid plugins
63 check_disk extra options for regex matching of filesystems and grouping of filesystems
64 for collective thresholds

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

103 check_udp2 removed. check_udp is now linked to check_tcp.c
104 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
105 as if mailqs were okay when the nagios user could not query the mail-queues

109 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
110 SSL plugins work with gnutls as well as OpenSSL
