sbv3000 Posted October 4, 2017 Share #1 Posted October 4, 2017 Hi All I run a syslog server for testing and diagnostics on my systems and found some interesting DNS communications between my NAS's and the Syno servers, see below. You can see from the MAC addresses which is from a real or xpe box Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire global.download.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire update.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire autoupdate.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire autoupdate.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire keymaker.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire pkgautoupdate.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire payment.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire global.download.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire checkipv6.synology.com Local User (MAC=68-05-CA-XX-XX-XX): 192.168.0.10 DNS -> 194.73.82.242 inquire checkip.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 194.73.82.242 inquire global.download.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 8.8.8.8 inquire checkipv6.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 194.73.82.242 inquire global.download.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 8.8.8.8 inquire checkip.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 8.8.8.8 inquire pkgautoupdate.synology.com Local User (MAC=00-11-32-XX-XX-XX): 192.168.0.15 DNS -> 8.8.8.8 inquire payment.synology.com Most of these are 'obvious' like the update requests, but the 'payment' and 'keymaker' are interesting.
