9 New check_icmp -s option to specify the source IP address
10 check_dns now sorts addresses for testing results for more than one returned IP (Matthias Urlichs)
11 Fix segfault in check_ntp_time and (deprecated) check_ntp (Bug #1862300)
12 check_disk should now work with large file systems (2TB+) on all archs that supports it
13 Fixed check_disk disk usage calculation when using --group=NAME (related to bug #1348746)

16 check_ntp_peer now checks for the LI_ALARM flag
17 Sync to latest Gnulib (includes new floorf function)
18 check_pgsql now successfully builds with postgres lib v8.3 (Bug #1878972)
19 check_procs now accepts --ereg-argument-array for a regular expression match to the argument array
20 Reverted back to using pst3 for Solaris systems. Fixed issues re: -m64 needed to compile on 64bit systems
21 If applicable, Gettext linked dynamically instead of statically
22 check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453)
23 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help
24 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
25 check_mysql and check_radius now try clearing password in processlist just like check_mysql_query
26 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)
27 negate now has the ability to replace the status text as well (-s, --substitute)
28 Added performance data to check_ping (Christian Schneemann)
29 Added support for --extra-opts in all C plugins (disabled by default, see configure --help)
30 Fixed passive option in check_by_ssh
31 On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN.
32 Fix linking against OpenSSL where libdl is required
34 1.4.11 13th December 2007
35 Fixed check_http regression in 1.4.10 where following redirects to
36 relative URLs on virtual hosts failed if both "-H" and "-I" were used
37 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
38 You should read the --help output so see which one is suitable for you. check_ntp_peer
39 implement stratum thresholds support (feature request #1703823).
40 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
41 as long as the thresholds range include -1. If no offset threshold is specified
42 and the offset is unavailable, will return UNKNOWN as well.
43 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
44 is "-1" as the default range starts at 0. See Examples in --help output.
45 Fixed broken usage2 in check_snmp and check_cluster
46 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
47 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
48 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
49 Fixed check_load argument handling when not passing triplets (bug #1831890)
50 Fixed buffer overflow in check_snmp (CVE-2007-5623)

52 Updated Nagios::Plugin to 0.22
53 VPATH problem fixed for compiling plugins-root
55 1.4.10 28th September 2007
56 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
57 check_http now explicitly asks HTTP/1.1 servers to close the connection
58 after completion of the response
59 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
60 is now deprecated. See --help for further information.
61 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
62 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
63 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
64 Thus accessibility of remote filesystems can be checked without any threshold comparison.
65 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
66 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
67 New check_disk -A option to select all filesystems explicitly
68 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
69 Passing -E after -p or -r results in UNKNOWN state, now
70 This is needed due to the new ignore feature
71 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
72 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
73 to check DHCP servers on remote networks
74 New check_dhcp -m/--mac option which allows for specifying the MAC
75 address to use in the DHCP request
76 The check_dhcp -r and -s options now accept host names, too
77 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
78 Fix check_smtp's handling of multiple-packet server responses
79 WARNING: Fix for negate which may break existing commands:
80 - stop evaluating command line options through shell twice
81 - enforce a full path for the command to run
82 The "negate" utility can now remap custom states
83 Check_radius now supports radiusclient-ng
84 The (undocumented) positional parameter parsing which check_radius used
85 instead of getopt(3) if 8 arguments were given is no longer available
86 Check_by_ssh now supports multiline output
87 IPv6 support can now be disabled using ./configure --without-ipv6
88 Fix check_ntp now honor ntp flags
91 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
92 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
93 check_snmp now supports Counter64
94 Fix compilation of check_ldap, check_radius and check_pgsql
95 check_load can optionally divide by number of cpus
96 Fix check_time returning wrong OK when time is before the epoch on some arch
97 Make check_http output more consistent
98 Fix possible check_http segfaults when following HTTP redirects
99 check_snmp don't warn anymore if something is printed on stderr
100 Fix check_tcp segfault when multiple expect strings are given
101 New option for check_tcp: -A/--all to test if all given expect strings match
103 1.4.8 11th April 2007
104 Respects --without-world-permissions for setuid plugins
105 check_disk extra options for regex matching of filesystems and grouping of filesystems
106 for collective thresholds
107 Better configure test for mysqlclient availability
108 Various check_ntp fixes
110 1.4.7 29th March 2007
111 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
112 Fixed MKINSTALLDIRS problem in po/
113 ./configure now detects if possible to compile check_mysql
114 Fixed broken HELO in check_smtp
115 check_icmp now allows to set a minimum number of hosts required for successs (-m)
116 check_icmp fix for *BSD when running for long time
117 check_ping times out 1 second quicker if host is unreachable
118 Root plugins installed with world executable
119 check_sybase from contrib now maintained in NagiosExchange
120 --with-nagios-user/group reinstated ./configure option
121 New --without-world-permissions ./configure option
123 1.4.6 5th February 2007
124 Reduced number of DNS lookups in check_ping and netutils.c for IPv6 configurations
125 Fixed compile problems with *BSD re: alloca.h

143 Please check at http://www.nagiosexchange.org for contributed plugins
144 Major bug fixes to check_disk where values were incorrectly calculated and alerted on.
145 check_udp2 removed. check_udp is now linked to check_tcp.c
146 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
147 as if mailqs were okay when the nagios user could not query the mail-queues
148 Compile problems with check_snmp fixed
151 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
152 SSL plugins work with gnutls as well as OpenSSL
153 check_mysql_query added to run arbitrary SQL commands, with threshold checking
