I just replaced the machine that runs ganglia.
httpd is being prevented from connecting to gmond.
All that is displayed is:
There was an error collecting ganglia data (127.0.0.1:8652): fsockopen
error: Permission denied
There's a message in /var/log/messages that blames selinux every time I
load the page.
and sealert says that I could change the behavior by setting
allow_ypbind or httpd_can_network_connect
allow httpd_t unreserved_port_t:tcp_socket name_connect;
I can see how letting httpd make arbitrary connections is bad, so how
can I punch a hole in the rule just for ganglia?
