Hi,

I'm trying to replace the inbuilt SSH test with one that does something
intelligent and have put this into ~hobbit/server/ext:

hobbit% cat server/ext/NGssh
#!/bin/sh

BBHTAG=NGssh           # What we put in bb-hosts to trigger this test
COLUMN=NGssh    # Name of the column, often same as tag in bb-hosts

$BBHOME/bin/bbhostgrep $BBHTAG | while read L
do
   set $L    # To get one line of output from bbhostgrep

   HOSTIP="$1"
   MACHINEDOTS="$2"
   MACHINE=`echo $2 | $SED -e's/\./,/g'`
   MSG="$BBHTAG status for host $MACHINEDOTS"
   reply = `ssh $MACHINE -l hobbit /usr/ucb/whoami`
   if [ "$reply" = "hobbit" ]
     COLOR=green
   else
     COLOR=red
   fi
   $BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`
       ${MSG}
       "
done
exit 0


Then the script is added to bb-hosts:

hobbit% grep NGssh ~hobbit/server/etc/bb-hosts
group-only conn|cpu|disk|info|memory|msgs|procs|NGssh|trends Campus
123.123.5.52 hostert # noping NGssh
123.123.1.12 hostick # noping NGssh
123.123.16.9 hostker # noping NGssh
123.123.3.11 hostel # noping NGssh
123.123.8.8 hostay # noping NGssh
123.123.5.49 hostmis # noping NGssh
123.123.3.17 hosteus # noping NGssh
123.123.1.11 hosty # noping NGssh
123.123.9.13 hostger # noping NGssh


What else needs to be done to action this script?
The script doesn't seem to be running and nothing is appearing in a
column. Scripts from the deadcat site mention a BBEXT variable but
it's not in any of the hobbit config files.

Thanks,
Mark

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) .

I originally looked at that, I've since concluded it's dodgy documentation
in that it's not specific or complete. The first bit is for client side,
the server-side bit lacks the final steps.

Cheers,
Mark

Here's how to do it:

In ~/server/etc/hobbitlaunch.cfg add:

[NGssh]
     ENVFILE /home/hobbit/server/etc/hobbitserver.cfg
     NEEDS hobbitd
     CMD $BBHOME/ext/NGssh.sh
     LOGFILE $BBSERVERLOGS/NGssh.log
     INTERVAL 5m


In ~/server/ext/NGssh.sh add:

$BBHOME/bin/bbhostgrep $BBHTAG | while read L
do
   set $L    # To get one line of output from bbhostgrep
   HOSTIP="$1"
   MACHINEDOTS="$2"
   MACHINE=`echo $2 | $SED -e's/\./,/g'`
   MSG="$BBHTAG status for host $MACHINEDOTS"


   reply=`ssh $MACHINE -l hobbit /usr/ucb/whoami`

exit 0
