What is remctl?
remctl (the client) and remctld (the server) implement a client/server protocol for running single commands on a remote host using Kerberos v5 authentication and returning the output. They use a very simple GSS-API-authenticated network protocol, combined with server-side ACL support and a server configuration file that maps remctl commands to programs that should be run when that command is called by an authorized user.

Remctl Commands
As a nagios administrator for Fermi you have basically three commands you can send to nagios using remctl (the port is 46157 for now):
- schedule - schedule a check on a host/service
- downtime - a host/service is known to be down, don't contact the contacts for a while
- acknowledge - Alert for host/service has been acknowledged so stop sending alert notices
Basic formats for host or service are:
remctl -p 46157 nagios02.slac.stanford.edu nagios ack host HOSTNAME COMMENT
remctl -p 46157 nagios02.slac.stanford.edu nagios ack service HOSTNAME SERVICENAME COMMENT
Command | Command | Format | Example |
|---|---|---|---|
acknowledge | remctl -p <port> <nagios-server-name> nagios <cmd> <host or service> <hostname> <service name> <comment> | ||

tell nagios to run a check for this host or service in M minutes | remctl -p 46157 nagios02.slac.stanford.edu nagios schedule host wain007 5 'run check in 5 mins' |
