# You can also add any MAC address OIDs that are newer or unknown to the file /usr/share/nmap/nmap-mac-prefixes.

A bash "one-liner" that requires serious explaining:
A Polycom phone will automatically reboot if you change anything in its webui (but you have to change something). This bash/awk/curl loop changes the length of time between sntp resyncs (basically a super-trivial setting) from 86400 seconds (1 day) to 86401. If you run this twice, you would need to change 86401 back to 86400. This is a super-dirty hack. Also note that this sets the sntp server to pool.ntp.org, and the time zone to Pacific (-28800). Although those settings will get overridden if you're setting those in your DHCP scope (which you should), please adjust as necessary.  To clarify, $i is an IP address. In this example, I get a list of phone IPs from asterisk and grep the ones I need to reboot, but you can iterate over any list of IPs.

for i in $(asterisk -rx 'sip show peers' | grep 192.168.10 | awk '{print $2}'); do  curl -s --user Polycom:456 -H application/x-www-form-urlencoded --referer http://$i/timeConf.htm -d "tcpIpApp.sntp.ad
