24 Sync to latest Gnulib (includes new floorf function)

26 check_procs now accepts --ereg-argument-array for a regular expression match to the argument array
27 Reverted back to using pst3 for Solaris systems. Fixed issues re: -m64 needed to compile on 64bit systems
28 If applicable, Gettext linked dynamically instead of statically
29 check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453)
30 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help
31 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
32 check_mysql and check_radius now try clearing password in processlist just like check_mysql_query
33 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)
34 negate now has the ability to replace the status text as well (-s, --substitute)
35 Added performance data to check_ping (Christian Schneemann)
36 Added support for --extra-opts in all C plugins (disabled by default, see configure --help)
37 Fixed passive option in check_by_ssh
38 On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN.
39 Fix linking against OpenSSL where libdl is required
41 1.4.11 13th December 2007
42 Fixed check_http regression in 1.4.10 where following redirects to
43 relative URLs on virtual hosts failed if both "-H" and "-I" were used
44 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
45 You should read the --help output so see which one is suitable for you. check_ntp_peer
46 implement stratum thresholds support (feature request #1703823).
47 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
48 as long as the thresholds range include -1. If no offset threshold is specified
49 and the offset is unavailable, will return UNKNOWN as well.
50 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
51 is "-1" as the default range starts at 0. See Examples in --help output.
52 Fixed broken usage2 in check_snmp and check_cluster
53 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
54 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
55 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
56 Fixed check_load argument handling when not passing triplets (bug #1831890)
57 Fixed buffer overflow in check_snmp (CVE-2007-5623)

59 Updated Nagios::Plugin to 0.22
60 VPATH problem fixed for compiling plugins-root
62 1.4.10 28th September 2007
63 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
64 check_http now explicitly asks HTTP/1.1 servers to close the connection
65 after completion of the response
66 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
67 is now deprecated. See --help for further information.
68 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
69 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
70 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
71 Thus accessibility of remote filesystems can be checked without any threshold comparison.
72 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
73 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
74 New check_disk -A option to select all filesystems explicitly
75 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
76 Passing -E after -p or -r results in UNKNOWN state, now
77 This is needed due to the new ignore feature
78 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
79 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
80 to check DHCP servers on remote networks
81 New check_dhcp -m/--mac option which allows for specifying the MAC
82 address to use in the DHCP request
83 The check_dhcp -r and -s options now accept host names, too
84 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
85 Fix check_smtp's handling of multiple-packet server responses
86 WARNING: Fix for negate which may break existing commands:
87 - stop evaluating command line options through shell twice
88 - enforce a full path for the command to run
89 The "negate" utility can now remap custom states
90 Check_radius now supports radiusclient-ng
91 The (undocumented) positional parameter parsing which check_radius used
92 instead of getopt(3) if 8 arguments were given is no longer available
93 Check_by_ssh now supports multiline output
94 IPv6 support can now be disabled using ./configure --without-ipv6
95 Fix check_ntp now honor ntp flags
98 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
99 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
100 check_snmp now supports Counter64
101 Fix compilation of check_ldap, check_radius and check_pgsql
102 check_load can optionally divide by number of cpus
103 Fix check_time returning wrong OK when time is before the epoch on some arch
104 Make check_http output more consistent
105 Fix possible check_http segfaults when following HTTP redirects
106 check_snmp don't warn anymore if something is printed on stderr
107 Fix check_tcp segfault when multiple expect strings are given
108 New option for check_tcp: -A/--all to test if all given expect strings match
110 1.4.8 11th April 2007
111 Respects --without-world-permissions for setuid plugins
112 check_disk extra options for regex matching of filesystems and grouping of filesystems
113 for collective thresholds
114 Better configure test for mysqlclient availability

117 1.4.7 29th March 2007
118 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
119 Fixed MKINSTALLDIRS problem in po/
120 ./configure now detects if possible to compile check_mysql
121 Fixed broken HELO in check_smtp
122 check_icmp now allows to set a minimum number of hosts required for successs (-m)
123 check_icmp fix for *BSD when running for long time
124 check_ping times out 1 second quicker if host is unreachable
125 Root plugins installed with world executable
126 check_sybase from contrib now maintained in NagiosExchange
127 --with-nagios-user/group reinstated ./configure option
128 New --without-world-permissions ./configure option
130 1.4.6 5th February 2007
131 Reduced number of DNS lookups in check_ping and netutils.c for IPv6 configurations

151 Major bug fixes to check_disk where values were incorrectly calculated and alerted on.
152 check_udp2 removed. check_udp is now linked to check_tcp.c
153 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
154 as if mailqs were okay when the nagios user could not query the mail-queues
155 Compile problems with check_snmp fixed
158 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
159 SSL plugins work with gnutls as well as OpenSSL
