Fixed crit/warn for check_disk perf data Fixed buffer overflow in check_procs Fixed error handling for UNIX sockets in netutils.c New -q and -o options for check_by_ssh which are handed over to ssh(1) as is Synced with latest GNUlib Fixed check_jabber always returns warning 1.4.5 Fixed bug in perl's is_hostname routine 1.4.4 New C based check_ntp.

Run make install as root to install SSL plugins work with gnutls as well as OpenSSL check_mysql_query added to run arbitrary SQL commands, with threshold checking libtool now required for development systems Notice: check_udp (compiled from check_udp.c) will be deprecated in the next release. check_udp2 should be used instead and will be renamed to check_udp 1.4.2 Fix for Redhat ES4 for check_dns and check_dig 1.4 IPv6 support in check_ping, check_by_ssh, check_http, check_ldap, check_smtp, check_tcp Internationalisation support Performance data added to most plugins check_disk now using GNU coreutils code New plugins - check_dhcp, check_icmp contrib/check_citrix has been replaced by contrib/check_ica* (requires packet_utils.pm in libexec) check_http --min changed to --pagesize, added max so min:max in check check_vsz and check_rss deprecated - functionality moved into check_procs check_swap % thresholds changed to measure amount free, instead of amount used check_disk syntax changes for -p, -m/-M, defaults to MB instead of kB check_procs -C expects no path for the command name
