     288=== Troublesome Hosts ===
    288289Sometimes a particular machine will act unpredictably and should be taken out of processing. To do this, go to each pantasks server in turn and remove the host, {{{ipp016}}} in the example below
    289290
     
    307308Running {{{neb-host}}} with no arguments gives you a summary of the above for all hosts.
    308309
     310=== Non-Troublesome Hosts ===
     311The same commands can be used for non-troublesome hosts.
     312
     313The {{{controller machines}}} command shows the list of hosts and 3 values: the first value is the number of connections from the pantasks server to the host. The {{{controller host off <hostname>}}} command has to be repeated as many times as the number of connections.
     314
     315It may also happen that a working host has to be removed (if it was temporarily added to better share the load because of some machine failure for instance). The {{{controller status}}} command details the activity for each connection. Hosts should be removed only if they have the RESP(onding?) or IDLE status (so wait for the running tasks to complete).
     316
     317Note: The {{{controller host check <hostname>}}} command only shows ONE connection status (SC: I can't tell which one).
     318
     319(SC TODO) {{{controller status}}} shows something looking like an addresse (e.g., 0.0.0.7d) which is different for each connection. It seems it's not possible to remove a particular connection. Am I right?
