1. Re: Getting arpnip working (John St.Martin (Home))
--- Begin Message ---
Hello Nicolas,
I have had this issue and opened a case with Sophos in the past but they
wouldn't do anything. The URM devices don't show as a layer 3 device in
Netdisco and appeared to me Netdisco wouldn't try to pull the ARP tables. I
worked around this a couple of ways:
1) on UTM, modified /var/sec/chroot-snmp/etc/snmpd.conf by adding
"sysServices 4" and then kill -HUP the snmpd process - any snmp changes or
a reboot seems to set it back to default and then after next netdisco
discovery it stops working
2) setup a cron entry to every 5 minutes make sure these devices show
layer3 support in netdisco - be careful if you have other Linux Net-SNMP
devices - may want to change the sql statement to meet the needs of your
environment:
# workaround for Sophos UTM devices so they are seen as L3 devices
*/5 * * * * $HOME/bin/netdisco-do psql -e "update device set
layers='00000100' where os='Linux' and vendor='Net-SNMP' and model='linux'"
> /dev/null 2>&1
I hope this helps and please let me know if anyone has any better
suggestions than what I have found.
John
