69 Fix linking against OpenSSL where libdl is required
71 1.4.11 13th December 2007
72 Fixed check_http regression in 1.4.10 where following redirects to
73 relative URLs on virtual hosts failed if both "-H" and "-I" were used
74 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
75 You should read the --help output so see which one is suitable for you. check_ntp_peer
76 implement stratum thresholds support (feature request #1703823).
77 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
78 as long as the thresholds range include -1. If no offset threshold is specified
79 and the offset is unavailable, will return UNKNOWN as well.
80 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
81 is "-1" as the default range starts at 0. See Examples in --help output.
82 Fixed broken usage2 in check_snmp and check_cluster
83 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
84 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).

92 1.4.10 28th September 2007
93 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
94 check_http now explicitly asks HTTP/1.1 servers to close the connection
95 after completion of the response
96 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
97 is now deprecated. See --help for further information.
98 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
99 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
100 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
101 Thus accessibility of remote filesystems can be checked without any threshold comparison.
102 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
103 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
104 New check_disk -A option to select all filesystems explicitly
105 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
106 Passing -E after -p or -r results in UNKNOWN state, now
107 This is needed due to the new ignore feature
108 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
109 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
110 to check DHCP servers on remote networks
111 New check_dhcp -m/--mac option which allows for specifying the MAC
112 address to use in the DHCP request
113 The check_dhcp -r and -s options now accept host names, too
114 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
115 Fix check_smtp's handling of multiple-packet server responses
116 WARNING: Fix for negate which may break existing commands:
117 - stop evaluating command line options through shell twice
118 - enforce a full path for the command to run
119 The "negate" utility can now remap custom states
120 Check_radius now supports radiusclient-ng
121 The (undocumented) positional parameter parsing which check_radius used
122 instead of getopt(3) if 8 arguments were given is no longer available
123 Check_by_ssh now supports multiline output
124 IPv6 support can now be disabled using ./configure --without-ipv6
125 Fix check_ntp now honor ntp flags
127 1.4.9 4th June 2006
128 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
129 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

143 for collective thresholds
144 Better configure test for mysqlclient availability

147 1.4.7 29th March 2007
148 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
149 Fixed MKINSTALLDIRS problem in po/
150 ./configure now detects if possible to compile check_mysql
151 Fixed broken HELO in check_smtp
152 check_icmp now allows to set a minimum number of hosts required for successs (-m)

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

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