Hmm... I still think that _could_ be the source (or part of it) of the issue. Below is run on a f18 system. $ host -a localhost. Trying "localhost" ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 28983 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;localhost. IN ANY ;; ANSWER SECTION: localhost. 0 IN A 127.0.0.1 localhost. 0 IN AAAA ::1 And (http_mon.sh uses wget by default): $ wget http://localhost/ --2013-12-27 09:55:29-- http://localhost/ Resolving localhost (localhost)... ::1, 127.0.0.1 Connecting to localhost (localhost)|::1|:80... failed: Connection refused. Connecting to localhost (localhost)|127.0.0.1|:80... failed: Connection refused. It first tries IPv6. curl (second http_mon.sh option) tries IPv6 first too: $ curl -v http://localhost/ * About to connect() to localhost port 80 (#0) * Trying ::1... * Connection refused * Trying 127.0.0.1... * Connection refused * couldn't connect to host * Closing connection #0 curl: (7) couldn't connect to host In your setup apache is probably listening on both localhost addresses, thus first connection attempt succeeds and it (apache) returns 403 Forbidden, preventing wget(curl) from trying IPv4 address. If apache listens only on 127.0.0.1 but not on ::1, then monitoring would succeed. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
