This is my /etc/sysctl.d/10-ipv6-privacy.conf: # IPv6 Privacy Extensions (RFC 4941) # --- # IPv6 typically uses a device's MAC address when choosing an IPv6 address # to use in autoconfiguration. Privacy extensions allow using a randomly # generated IPv6 address, which increases privacy. # # Acceptable values: # 0 - don’t use privacy extensions. # 1 - generate privacy addresses # 2 - prefer privacy addresses and use them over the normal addresses. net.ipv6.conf.all.use_tempaddr = 2 net.ipv6.conf.default.use_tempaddr = 2
(You will notice that the use_tempaddr value is 2. That was, I think, changed when I was trying to fix this problem. But it still doesn't work.) The output of cat /proc/sys/net/ipv6/conf/default/use_tempaddr is 2 The output of cat /proc/sys/net/ipv6/conf/all/use_tempaddr is 2 The output from those used to be 0, but again I changed to 2 as I tried to fix the problem. It still doesn't work. ------------------------------------------------------------------------ *From:* Marc Deslauriers <mailto:[email protected]> *Sent:* Wednesday, January 30, 2013 9:24AM *To:* mcellius <mailto:[email protected]> *Subject:* [Bug 1108545] Re: In Raring, the reported IPv6 address contains the computer's mac address, compromising security. Could you attach the contents of your /etc/sysctl.d/10-ipv6-privacy.conf file? Also, what is the result of the following two commands? $ cat /proc/sys/net/ipv6/conf/default/use_tempaddr $ cat /proc/sys/net/ipv6/conf/all/use_tempaddr Thanks. ** Information type changed from Private Security to Public Security ** Package changed: ubuntu => network-manager (Ubuntu) ** Package changed: network-manager (Ubuntu) => procps (Ubuntu) ** Changed in: procps (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1108545 Title: In Raring, the reported IPv6 address contains the computer's mac address, compromising security.
