Bug filled in Samba buzilla: https://bugzilla.samba.org/show_bug.cgi?id=10730 Since it seems to be an upstream issue...

The crash does not seem to be a security issue since it is related to a specific configuration and therefore this is a normal bug. ** Information type changed from Public Security to Public -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1335502 Title: Samba4 does not work with IPv6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1335502/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I have trouble believing such a common daemon is so brittle in the face of IPv6; further investigation would be very helpful. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1335502 Title: Samba4 does not work with IPv6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1335502/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1335502] Re: Samba4 does not work with IPv6
Hey Seth, I completely agree with you... If true, this problem is serious (and unbelievable, it seems that Canonical have no Q.A. to deal with IPv6, or something like that, I do not want to be rude, but make Ubuntu a better O.S.) but, in the end of the day, I managed to make it work. To make Samba4 safer against this problem (that come by default), we need to provision the domain passing the following option: --function- level=2008_R2 to samba-tool. Example with IPv6 working on Samba4 AD DC: --- samba-tool domain provision --realm domain.com.br --domain DOMAIN --adminpass Test1234Lol --server-role=dc --use-rfc2307 --function-level=2008_R2 --- This way, Samba4 will behave okay when you have IPv6 on your network. Samba4 AD DC with IPv6 enabled: --- root@ubuntu-ad-1:~# host -t SRV _ldap._tcp.domain.com.br _ldap._tcp.domain.com.br has SRV record 0 100 389 ubuntu-ad-1.domain.com.br. root@ubuntu-ad-1:~# host ubuntu-ad-1.domain.com.br ubuntu-ad-1.domain.com.br has address 192.168.1.221 ubuntu-ad-1.domain.com.br has IPv6 address 2008:xxx:200:3f6::10 --- Also, I noted that, 2008_R2 level do NOT fix this if you just tries to raise up your Samba AD DC, after enabling IPv6, for example, by doing: --- samba-tool domain level raise --domain-level 2008_R2 --forest-level 2008_R2 --- It will not fix the problem... You need to start from scratch, using 2008_R2 level from the beginning, to not hit this problem. So, this is still a BUG but, less serious if you not use the defaults to provision your domain at first... Cheers!

I did more tests this weekend on this... In fact, it is easier to replicate this problem... For example, if you have Samba4 working okay in an IPv4-Only environment and then, you just enable IPv6 (and reboot), Samba4 will not start anymore... Also, I tried to run samba_dnsupdate --verbose after enabling IPv6 at etc/network/interfaces (ifdown eth0 ; ifup eth0) and, before a reboot (while Samba4 is still running), without success... -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1335502 Title: Samba4 does not work with IPv6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1335502/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
