Description
BOINC is failing to use Mac's resolver libraries and fails to properly implement IPv6 resolver internally.
My Setup: Mac OSX 10.6.6, BOINC 6.12.11 or 6.10.58, DNS resolvers: IPv6 2001:470:882a::1 and 2001:470:20::2
BOINC reports unable to connect to internet:

Replying to charlief:
I'll start with the second question first. The IPv6 resolver is a caching nameserver that is running in my network. It receives requests from my local machines and if the requested address is not available in the cache, it contacts the nameserver hierarchy to resolve the name to an IP address. The address requested may be an IPv4 or an IPv6 address depending on the application making the request. The only portion that is using IPv6 exclusively is transport between my local desktop and the caching nameserver on my local network. The caching nameserver has both IPv4 and IPv6 connectivity to the Internets for resolving names. The local machine also has IPv4 connectivity for communications to webservers and such. I had been testing with using an IPv6 only resolver in my local IPv6 enabled network.
The two IPv6 addresses listed are: 2001:470:882a:1 - local IPv6 caching nameserver on my network (not publicly available) 2001:470:20::2 - publicly accessible IPv6 caching nameserver run by Hurricane Electric
Now on to the test setup.
- For you to replicate this bug, you will need to have IPv6 connectivity between your test Mac and either a local caching nameserver accessible over IPv6, or the IPv6 internet where you can access the Hurricane Electricn ameserver at 2001:470:20::2. Confirm proper IPv6 connectivity for your Mac - it should show an IPv6 address just below the Search Domains box.
- Then the DNS Server setting should be set to "2001:470:20::2" or to your local caching IPv6 nameserver, but only IPv6 addresses should be in the box.
- You can confirm connectivity to the HE server by opening a terminal window and using "ping6 2001:470:20::2"
- You can confirm your machine is able to resolve names to IPs using this server by "dig A boinc.berkeley.edu @2001:470:20::2" which should return a CNAME and an A result in the ANSWER SECTION. (An A record is a mapping between a name and IPv4 address. If an IPv6 address is needed, that is stored in a AAAA record. CNAME is a name that maps to another name)
- As a final DNS check, you can use "nslookup boinc.berkeley.edu" to show what the operating system will do when asked for the IPv4 address related to the name boinc.berkeley.edu - it should show the nameserver it contacted, the address it used and the answer (nslookup will look up an A record by default, in this case a canonical name is returned and that name is resolved to an IPv4 address).
Here is the result from my machine:
oberon:~ gawul00$ nslookup boinc.berkeley.edu Server: 2001:470:882a:200::2 <----------------------------- Request being made to this server Address: 2001:470:882a:200::2#53 <------------------------- Server address and port Non-authoritative answer: <--------------------------------------- is an answer from my local resolver, not the Berkeley server directly boinc.berkeley.edu canonical name = boinc.SSL.berkeley.edu. <-- Request for boinc.berkeley.edu returned another c-name Name: boinc.SSL.berkeley.edu <----------------------------------- Lookup the c-name record Address: 128.32.18.189 <------------------------------------------- which returns this IP address oberon:~ gawul00$
Now try to use Boinc - debugs show that it is unable to resolve names, however the OS continues to be able to do so:
oberon:~ gawul00$ nslookup bam.boincstats.com Server: 2001:470:882a:200::2 Address: 2001:470:882a:200::2#53 Non-authoritative answer: Name: bam.boincstats.com Address: 217.67.244.101 oberon:~ gawul00$ nslookup www.google.com Server: 2001:470:882a:200::2 Address: 2001:470:882a:200::2#53 Non-authoritative answer: www.google.com canonical name = www.l.google.com. Name: www.l.google.com Address: 74.125.93.105 Name: www.l.google.com Address: 74.125.93.147 Name: www.l.google.com Address: 74.125.93.106 Name: www.l.google.com Address: 74.125.93.99 Name: www.l.google.com Address: 74.125.93.104 Name: www.l.google.com Address: 74.125.93.103 oberon:~ gawul00$

Thank you for your replies. Unfortunately, I have not been able to get ping6 to work on my system; I suspect it is a problem with my Internet modem / router (2-wire 3800HGV-B with AT&T U-Verse service), even though I've tried using DMZ-plus with a hard-wired Ethernet connection, and even though the router manufacturer claims it is IPv6-capable. Ping6 reports UDP connect: No route to host.
Rather than spending more time trying to reproduce this here, can I ask you to try the following version of BOINC? http://boinc.berkeley.edu/dl/boinc_6.10.43_macOSX_universal.zip.
BOINC uses the libraries libcurl and c-ares to do its Internet communications. c-ares 1.7.0 introduced asynchronous name resolving supporting IPv6, but caused problems on some network configurations so we reverted to c-ares 1.6.0 which did not have IPv6 support. BOINC version 6.10.43 still used c-ares 1.7.0, so it would be great to know if that works with your IPv6 resolver.
If that works, I would then like to build you a test drop of BOINC built with a patched version of c-ares 1.7.0. I have confirmed that my patch fixes the original issue with c-ares 1.7.0, but I have not been able to confirm that it does work properly with IPv6.
By coincidence (or perhaps not), the network configurations that failed with standard c-ares 1.7.0 were the same 2-wire 3800HGV-B router with AT&T U-Verse service. The problem occurs when the Mac's Network System Preferences are set to the default Airport settings, which use the router as the DNS Server. If I use that configuration, I get the same failures. The problem is that the standard c-ares 1.7.0 code doesn't fall back to trying IPv4 for the particular error it gets from the router's DNS server. If I instead configure the Mac to use different (external) DNS servers, standard c-ares 1.7.0 works fine. My patch (which was not in BOINC 6.10.43) simply makes c-ares fall back to IPv4 for any IPv6 failure.
Thanks in advance.

I had a chance to try out 6.10.43 and found the same behavior. With only an IPv6 resolver in my network connection properties, BOINC fails to resolve DNS. When I add an IPv4 resolver, I am able to connect successfully.
WIth only an IPv6 resolver configured:

I am not able to reproduce this, but I'm not sure if I'm setting my network configurations the same as yours. I am setting "Configure IPv" to "Using DHCP" (since I am behind a router with NAT), setting "DNS server; to "2001:470:882a::1, 2001:470:20::2" and leaving "Search domains" blank. If this is not correct, please post the full procedure for setting the Mac to reproduce this.
Also, please explain why you would want to use an "only IPv6 resolver", given the many Internet servers that do not support IPv6.
Thank you.
