Hello. I tried to get basic samba configuration working with ipv6 before getting full pdc on ipv6. nmbd crashes when it try to start. Last line in the logfile is: nmbd/nmbd.c:696(open_sockets)

smbd is running on tcp6 :::139 and tcp6 :::445, but i cant get with any windows computers connected to it.

When i mount local on the linux machine with 'mount.cifs //fd00::1/data /mnt/somewhere', then it works.

When i try on a windows machine with \\fd00::1 i get an error. I also tried \\[fd00::1] but no change.

Network connection:
Linux: fd00::1/64
Windows 7: fd00::2/64
Windows xp: fd00::3/64

i can ping from every computer the other one with ping6(linux) and ping -6 (windows). The firewalls on the windows computers are disabled.

This is the smb.conf i use:

workgroup = fh-koeln
netbios name = gentoo
security = share

comment = Data
path = /home/samba/public #there is an ~200mb iso in it
read only = Yes
guest ok = Yes

When i change the ip's from ipv6 to ipv4 everything works normal.

Lowering severity. I don't think it's a show stopper for 3.5.4 (we will try to fix it for 3.5.4 anyway)

have a look at 


this works for me at least with 4.0.6 smbd and w2k8r2 as client. The plain or square bracket litteral ipv6 address format is not supported by windows.
