[Samba] Samba name/address mismatch

[Francesco Alfano]

Hello
In samba log file I've a message like this:

[2011/01/18 16:04:04,  0] lib/util_sock.c:matchname(1749)
   matchname: host name/address mismatch: ::ffff:192.168.168.202 != 
pc-ser-tun.eda
that fills log.smbd.

I've never used ipv6 and
ping pc-ser-tun.eda returns:
PING pc-ser-tun.eda (192.168.168.202) 56(84) bytes of data.
64 bytes from pc-ser-tun.eda (192.168.168.202): icmp_seq=1 ttl=128 
time=0.092 ms

and in smb.conf i've this entry:
hosts allow = 127. 192.168.1. 192.168.168.

can you help me to remove this mismatch from log.smbd ?

Thanks in advance.
