Sure, have a look at the man page for snm-discover. You could run it
from cron at whatever period you liked. Note that you probably need to
put this into a script which cron runs. In the script set SNMHOME and
possibly the user SNMDBDIR (I thinkm, the manual is not around at the
moment to look this up).

Not that you need to run one copy of snm_discover for each subnet, eg:

for i in net1 net2 net3; do
    snm_discover $i &

You might note that SNM has a 1024 object limitation, so doing major discovers isn't all that useful.

However, if you do 'snm_discover -w -v' as root in a window, then ping new hosts (or otherwise send traffic to them), they automagically get passively discovered and put into the SNM database.

So it would be easy to combine this with a pinging script that pings hosts recently added to host tables (use diff to get the list), to automatically "notice" new hosts. Probably simpler than running discover on a whole bunch of subnets. ---------------------------------------------------------------------- Dr. Peter J.
