Hi nmap-dev, Attached is ganglia-gmetad-info.nse which is designed to retrieve system information from a Ganglia Meta Daemon, as per the script ideas page on secwiki.org I've also attached a tiny modification to the Ganglia Monitoring Daemon script ( ganglia-gmond-info.nse --- see: http://seclists.org/nmap-dev/2011/q2/875 ) to stop the script returning data from a Ganglia Meta Daemon. These two services are almost identical. If you aren't familiar with Ganglia, the monitoring daemon (port 8649) returns data for hosts in a single cluster whereas the meta daemon (port 8651) returns data for hosts in multiple clusters. Nmap currently reports both services as "ganglia" --- can anyone foresee any issues with changing the nmap-service-probes for Ganglia from: match ganglia m|^<\?xml version=\"1\.0\".*<!DOCTYPE GANGLIA_XML.*<GANGLIA_XML VERSION=\"([^\"]+)\" SOURCE=\"([^\"]+)\">.*<CLUSTER NAME=\"([^\"]+)\" LOCALTIME=\"\d+\" OWNER=\"([^\"]+)\"|s p/Ganglia XML Grid monitor/ v/$1/ i/Cluster name: $3; Owner: $4; Source: $2/ d/specialized/ to: match ganglia-metad m|^<\?xml version=\"1\.0\".*<!DOCTYPE GANGLIA_XML.*<GANGLIA_XML VERSION=\"([^\"]+)\" SOURCE=\"gmetad\">.*<CLUSTER NAME=\"([^\"]+)\" LOCALTIME=\"\d+\" OWNER=\"([^\"]+)\"|s p/Ganglia XML Grid monitor/ v/$1/ i/Cluster name: $3; Owner: $4; Source: $2/ d/specialized/ match ganglia-gmond m|^<\?xml version=\"1\.0\".*<!DOCTYPE GANGLIA_XML.*<GANGLIA_XML VERSION=\"([^\"]+)\" SOURCE=\"gmond\">.*<CLUSTER NAME=\"([^\"]+)\" LOCALTIME=\"\d+\" OWNER=\"([^\"]+)\"|s p/Ganglia XML Grid monitor/ v/$1/ i/Cluster name: $3; Owner: $4; Source: $2/ d/specialized/ ... in order to reflect the difference in the service type? (Note the difference in the "source" property of the GANGLIA_XML node.) Is this a good idea? The difference between the two is currently only reported (in service fingerprinting mode) in the version, as follows: 8649/tcp open ganglia syn-ack Ganglia XML Grid monitor 3.0.7 (Cluster name: Fyodor's Cluster; Owner: Fyodor; Source: gmond) 8651/tcp open ganglia syn-ack Ganglia XML Grid monitor 3.0.7 (Cluster name: Fyodor's Cluster 2; Owner: Fyodor; Source: gmetad) ( Note the difference in "source:" ) If the probes aren't changed then both scripts will be triggered by the "ganglia" service if the user is running all discovery scripts. If the probes can't be changed for some unforeseen reason, would it be worth combining these two scripts into one? Furthermore, both scripts currently print the following in debugging mode if the service type is incorrect: ("%s: %s:%s is not a Ganglia Monitoring Daemon."):format(script_name, host.targetname or host.ip, port.number) or: ("%s: %s:%s is not a Ganglia Meta Daemon."):format(script_name, host.targetname or host.ip, port.number) ... based on the aforementioned GANGLIA_XML nodes. Perhaps a better solution would be to return the error message even when debugging is off and advise the user to try the other script? Finally, what do you think of the (rather verbose) output? Should verbosity be a script argument? If so, what data do you consider important for the standard output? Feedback is welcomed and appreciated. ----------------------------------- description = [[ Retrieves system information from a listening Ganglia Meta Daemon.
