  1. Command Server How to manage programs from various hosts sending displays to various display heads

  2. Our Problem • DM, MEDM, DM2K, StripTool and Matlab screens served by different hosts onto the same head. • VMS and Unix/Legacy system and Epics in the mix. • Need to manage host processes AND displays on single heads.

  3. CmdSrv - an SSH-like solution • A file-driven command server process runs on a host. • The file determines which requests are legal from whom. • Each request is satisfied as a new thread from the command server.

  4. Features • Request information on all currently active threads (individual requests) • PID • Target Display Head • Time of connection • Kill all processes associated with any display head • Kill all processes

  5. Current Status • Server available for Solaris (any Unix) • Client available for VMS or Solaris • Author: Ron MacKenzieronm@slac.stanford.edu • Documentation at http://www.slac.stanford.edu/grp/cd/soft/cmdSrv/index.html
