[Samba] matchname messages filling logs - howto stop?

[David C. Rankin]

Listmates,

	I have had a few boxes where the 'matchname' message is filling my syslog with
one new message ever ~40 seconds or so. No performance problems, just the log
annoyance. An example of the messages are:

	The message is generated between an XP box and the samba server which is setup
in standalone mode. The basic configuration is:

[global]
        workgroup = RB_LAW
        server string = Samba %v
        map to guest = Bad User
        log file = /var/log/samba/log.%m
        max log size = 100
        smb ports = 139
        name resolve order = wins lmhosts bcast
        time server = Yes
        printcap name = cups
        disable spoolss = Yes
        show add printer wizard = No
        os level = 58
        dns proxy = No
        wins server = 192.168.7.15
        admin users = david
        hosts allow = 192.168.7., 192.168.6., 192.168.8., 192.168.5., 127.
[homes]
        comment = Home Directories
        read only = No
        browseable = No
        browsable = No

[samba]
        comment = Nemesis Law
        path = /home/samba
        valid users = @office, anna
        force group = office
        read only = No
        inherit permissions = Yes

[printers]
        comment = All Printers
        path = /var/spool/samba
        create mask = 0700
        guest ok = Yes
        printable = Yes
        use client driver = Yes
        browseable = No
        browsable = No

[print$]
        path = /var/lib/samba/drivers
        write list = @adm, root
        inherit permissions = Yes
        guest ok = Yes


	I have had this same problem on several boxes and I haven't been able to chase
down the cause. I get that samba is saying that there is a mismatch between the
hostname and the address for the IPV6 address ::ffff:192.168.7.127 !=
Adrienne-PC.rbpllc.com. The problem is I don't know where samba is caching this
information or how to prevent samba from considering this box and address to be
mismatched.

	I apologize if this has been asked and answered before, but I haven't had the
time to monitor the list on a daily basis as I have had in the past. Could
somebody shed some light on how I can solve this problem. I would rather not
simply drop the log level to hide the error, I would prefer to fix it. Thanks.
