I just installed amd64 LL Desktop on my Hyper-V server. Within 5 minutes of connecting it to my local network, I got an alert from my APC UPS that it had detected an unauthorized IP attempting to access the SNMP interface. Come to find out, the IP was my new Ubuntu install.
All I had done in those 5 minutes was to do an apt-get update & upgrade.
Any ideas on this weird behavior?
