I found out about this as the Fedora dhclient-script (part of ISC dhcp-4.2.0) wipes out resolv.conf and replaces it with whatever the dhclient receives. Please discuss if this is reasonable behaviour (by tor) and/or hwo we could work around this. This really should only affect exit relays, right? Nope. No exit here. Still it dies. I wonder how common Udo's situation is. Not everyone has ipv6 yet. Also the implementation might differ from place to place. My experience was first with the wide-dhcp (no script, just simple hacks), now it is isc dhclient as it is distributed with Fedora. Need to patch dhclient to work with ppp (!) and to patch dhclient-script to make it work with prefix delegation. So if we don't use ppp but still use isc dhclient we might see this issue in more places as dhclient-script fills resolv.conf with the input from the dhcp-server(s). So yes, the problem is possible but not too often... Udo *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

See my other response about this problem. isc dhclient + dhclient-script as distributed with Fedora (dunno if it is the same script in other distro's) replaces resolv.conf with the info received from the dhcp server(s). In my xs4all.nl case the ipv6 dhcp server gives me ipv6 number for the nameservers.

How does Gmail know my local time zone (therefore ignoring the time zone of the Tor exit node) and what else can it see?
Hello, I have yet another question that relates to the effectiveness of Tor. Gmail (and therefore presumably other webmail operators) knows my computer's time zone. It does not know the time per se but the time zone as set (in Ubuntu) through clicking on the clock, selecting preferences, then choosing location. Obviously this ignores the time (based on the location) of the Tor exit node. I do not know how Gmail knows my computer's time zone, and, in which case, what other local information it can know. Does anyone know how Gmail can do this and what other information from the client computer can be viewed. In other words, why can Gmail not, in theory, also view the real local IP? Thanks.

Did you select a time zone when you set up the account? I assume you are using Torbutton, which blocks Javascript being used to read your local clock.
