ARP Message Daily Run Output Question

[joeduffy]

So every day I receive an email saying that it is checking for package vulnerabilities this is normal I think it cant resolve the domain for some reason. But today I received one with an arp message and as a result i am logged out of my mounted network drive in windows. Both mac addresses are wireless access points with ips outside the routers dhcp range the freenas server also is outside dhcp. I believe 172.16.0.6 is an older windows xp machine connected to the network via a ddwrt wireless bridge. Probably what caused the mac address change is the access points reshuffling themselves because there is no way to lock to a specific BSSID.
What I do not understand it why other computers got logged out of the share? How would I go about preventing this?

freenas.local kernel log messages:
> arp: 172.16.0.6 moved from (TPLINK)74:ea:3axxx to (SONIC)00:40:10xxx on re1

Checking for packages with security vulnerabilities:
pkg: http://vuxml.freebsd.org/freebsd/vuln.xml.bz2: No address record
pkg: cannot fetch vulnxml file

-- End of security output --

Could the devices be going to sleep and thus loosing the connection to the server?

in any case the arp messages can be silenced by adding

Code:

net.link.ether.inet.log_arp_movements=0

as a loader variable (if I recall correctly, I'm not near my freenas box at the moment.) If you want to avoid having to reboot to make the loader variable take effect, then you can issue the following command as root on the command line

Code:

sysctl net.link.ether.inet.log_arp_movements=0

I got these arp movement messages all the time when the various apple TVs at home would go to sleep, adding that boot loader variable eliminated them.

freenas version and hardware specs?

4GB of RAM isn't going to cut it for FreeNAS. Get appropriate hardware that at least meets the minimum specs.

Im going to upgrade my network by digging trenches and running conduit for Ethernet soon so this will become less of a problem. I was interested in why windows clients sporadically forget their credentials and require you to log in again. This seemed like a obvious reason. Some sort of security feature to prevent mac address spoofing?.
The system is quite stable in its current config current up time in excess of a month.

System Specs:
FreeNas 9.2.1.9 64bit
MOBO: Biostar G31-M7 TE
CPU: Intel Celeron E1500
HDD: 3x 2TB Seagate Barracuda (RAIDZ1 setup)
RAM: 2x2GB DDR2 800mhz
CASE: Found Laying By The Side Of The Road
PSU: Seasonic G-360 80 Plus Gold
UPS: APC Smart UPS 1500

No one cares if you think it's stable. We can guarantee you it's not stable with only 4GB of memory. One day your system will just poof and nuke everything. Double check your backups.

This.

8GB is the minimum spec for a reason. That's just for a basic filer and you're running jails on top of that.........
