Re: [hobbit] Server side EXT script not running or appearing on web page

You shouldn't add external tests to bb-hosts. You add them to etc/bb-bbexttab.

-Dan

$ head -30 etc/bb-bbexttab
# bb-bbexttab: configuration file for launching external scripts
#
# Format:
#
#    host: misc settings : external scripts list
#    localhost: misc settings : external scripts list
#    : misc settings : external scripts list
#
#    host can be FQDN (fully qualified domain name) or
#       just a plain hostname but it is preferred that you
#       use a FQDN.
#    localhost: using this specifies that the scripts
#       specified on the line are to be launched on all clients
#
#    The same host can be specified on multiple lines to aid readability
#
#    Misc settings field is unimplemented ...
#        For future use...
#
#    You can override the default sleep between cycles
#      by addding a time qualifier to the script:
#      e.g.: localhost: script1;600
#      **NOTE** The sleep delimiter in BBEXT of bbdef.sh was
#               ':' (script1:600) but here it is ';'
#               in order to keep the same format as the
#               other bb-*tab files (the : is used to delimit
#               file entry fields in all bb-*tab files) .
#               The time qualifier is specified in SECONDS
