59 On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN.
60 Fix linking against OpenSSL where libdl is required
62 1.4.11 13th December 2007
63 Fixed check_http regression in 1.4.10 where following redirects to
64 relative URLs on virtual hosts failed if both "-H" and "-I" were used
65 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
66 You should read the --help output so see which one is suitable for you. check_ntp_peer
67 implement stratum thresholds support (feature request #1703823).
68 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
69 as long as the thresholds range include -1. If no offset threshold is specified
70 and the offset is unavailable, will return UNKNOWN as well.
71 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
72 is "-1" as the default range starts at 0. See Examples in --help output.
73 Fixed broken usage2 in check_snmp and check_cluster
74 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")

85 check_http now explicitly asks HTTP/1.1 servers to close the connection
86 after completion of the response
87 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
88 is now deprecated. See --help for further information.
89 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
90 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
91 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
92 Thus accessibility of remote filesystems can be checked without any threshold comparison.
93 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
94 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
95 New check_disk -A option to select all filesystems explicitly
96 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
97 Passing -E after -p or -r results in UNKNOWN state, now
98 This is needed due to the new ignore feature
99 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
100 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
101 to check DHCP servers on remote networks
102 New check_dhcp -m/--mac option which allows for specifying the MAC

105 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
106 Fix check_smtp's handling of multiple-packet server responses
107 WARNING: Fix for negate which may break existing commands:
108 - stop evaluating command line options through shell twice
109 - enforce a full path for the command to run
110 The "negate" utility can now remap custom states
111 Check_radius now supports radiusclient-ng
112 The (undocumented) positional parameter parsing which check_radius used
113 instead of getopt(3) if 8 arguments were given is no longer available
114 Check_by_ssh now supports multiline output
115 IPv6 support can now be disabled using ./configure --without-ipv6
116 Fix check_ntp now honor ntp flags
119 Inclusion of contrib/check_cluster2 as check_cluster with some improvements

138 1.4.7 29th March 2007
139 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
140 Fixed MKINSTALLDIRS problem in po/
141 ./configure now detects if possible to compile check_mysql
142 Fixed broken HELO in check_smtp
143 check_icmp now allows to set a minimum number of hosts required for successs (-m)

145 check_ping times out 1 second quicker if host is unreachable
146 Root plugins installed with world executable

173 check_udp2 removed. check_udp is now linked to check_tcp.c

175 as if mailqs were okay when the nagios user could not query the mail-queues
176 Compile problems with check_snmp fixed
179 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
