Is there a delimiter? Here's a redacted sample: #----------------------------------------------------------------------- #### Ingest servers (production) #----------------------------------------------------------------------- mioing-1 rstevens@ing1-r1 rstevens@ing2-r1 rstevens@ing3-r1 rstevens@ing4-r1 rstevens@ing5-r1 rstevens@ing6-r1 rstevens@ing7-r1 rstevens@ing8-r1 rstevens@ing9-r1 rstevens@ing10-r1 rstevens@ing11-r1 mioing-2 rstevens@ing12-r1 rstevens@ing13-r1 rstevens@ing14-r1 rstevens@ing15-r1 rstevens@ing16-r1 rstevens@ing17-r1 rstevens@ing18-r1 rstevens@ing19-r1 rstevens@ing20-r1 rstevens@ing21-r1 rstevens@ing22-r1 mioing mioing-1 mioing-2 #----------------------------------------------------------------------- That is three lines (it'll probably wrap on the list). Everything on the line starting "mioing-1" is a SINGLE line. Essentially, each line starts with a "cluster name", a space, then a space-separated list of remote machines OR another cluster name. I use "rstevens@hostname" on the host entries because I have to log in that way on those machines (they don't have my ssh keys). This /etc/clusters (or ~/.clusterssh/clusters) file allows me to do things like "cssh mioing-1" to get ssh sessions to the first 11 servers, "cssh mioing-2" to get ssh sessions to the second 11 servers, and (if I can tolerate tiny little windows), "cssh mioing" to get sessions to all 22 servers (note that the third line consists of a cluster name of "mioing", followed by two previously-defined cluster names). I also have this in my /etc/csshrc (or ~/.clusterssh/config) file: terminal_reserve_top = 28 auto_close = 1 key_addhost = Alt-h This keeps the terminals from overlapping their windows, closes them after I log out of the session and lets me use "ALT-H" to open a window to add a new host to those already displayed. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - 500: Internal Fortune Cookie Error - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
