Hi List, Using nocpulse user I am creating the probe fron UI. Client end rhnmd is running and port 4545 is accessible from spacewalk server. I am able to login using that ssh-dss key. Whatever the prove I am creating it's on "PENDING, Awaiting Update" state. SatConfig-generator is already installed. Selinux is in disabled mode. 775 permission is there for "/var/lib/nocpulse" . Below is my "/var/log/nocpulse/execute_commands.log" files output. 2011-07-20 20:46:03 154: Finished with command 164 2011-07-20 20:46:03 157: Finished processing commands 2011-07-20 20:46:03 95: Freshening heartbeat file /var/lib/nocpulse/commands/heartbeat 2011-07-20 20:46:03 176: No commands executed, sleeping 60 seconds 2011-07-20 20:47:03 96: Starting queue run 2011-07-20 20:47:03 95: Freshening heartbeat file /var/lib/nocpulse/commands/heartbeat 2011-07-20 20:47:03 104: Attempting to fetch commands (attempt 0) 2011-07-20 20:47:03 95: Queue server URL: <a href="https://spacewalk.example.com/satconfig/cgi-mod-perl/fetch_commands.cgi?cluster_id=203a64827eb3&node_id=2&role=lead&version=1.0">https://spacewalk.example.com/satconfig/cgi-mod-perl/fetch_commands.cgi?cluster_id=203a64827eb3&node_id=2&role=lead&version=1.0</a> 2011-07-20 20:47:03 95: Successfully got command list 2011-07-20 20:47:03 95: CommandQueueParser parsing 411 bytes 2011-07-20 20:47:03 95: Parser::parse returning NOCpulse::CommandQueue=HASH(0xa17c70c) 2011-07-20 20:47:03 95: CQ::fetch_commands returning NOCpulse::CommandQueue=HASH(0xa17c70c) 2011-07-20 20:47:03 121: Fetched 1 commands 2011-07-20 20:47:03 130: Running command 164 2011-07-20 20:47:03 131: Command line is: /usr/bin/scheduleEvents 2011-07-20 20:47:03 95: Attempting to run command 164 2011-07-20 20:47:03 95: Last started: 164; Last completed: 164 2011-07-20 20:47:03 95: 164 is not executable (old, last started 164, last completed 164) 2011-07-20 20:47:03 150: Not executing command 164: 164 is not executable (old, last started 164, last completed 164) /\ dE
