[Samba] matchname messages filling logs - howto stop?
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:
Jan 11 13:43:03 nemesis smbd[2246]: [2010/01/11 13:43:03, 0]

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.

Serg >?????? Thank you for the response. I know there is an IP mismatch. That, I get. What I need your help on is how I tell samba to forget about the old IP address of 192.168.7.127 and learn the correct address for Adrienne-PC? Where is this cached and how do I get rid of it? Samba isn't seeing something correctly. For example, here is the same problem with a machine named reception (in the reception area): Jan 13 12:43:19 nemesis smbd[7449]: Matchname failed on RECEPTION.rbpllc.com ::ffff:192.168.7.150 Jan 13 12:50:46 nemesis smbd[7474]: [2010/01/13 12:50:46, 0] lib/util_sock.c:1564(matchname) Jan 13 12:50:46 nemesis smbd[7474]: matchname: host name/address mismatch: ::ffff:192.168.7.150 != RECEPTION.rbpllc.com Jan 13 12:50:46 nemesis smbd[7474]: [2010/01/13 12:50:46, 0] lib/util_sock.c:1685(get_peer_name) Jan 13 12:50:46 nemesis smbd[7474]: Matchname failed on RECEPTION.rbpllc.com ::ffff:192.168.7.150 Samba is saying there is a mismatch between reception and the IP of 192.168.7.150 -- but that is WRONG! 13:19 nemesis:~> ping reception PING reception.rbpllc.com (192.168.7.150) 56(84) bytes of data. 64 bytes from RECEPTION.rbpllc.com (192.168.7.150): icmp_seq=1 ttl=128 time=3.16 ms 64 bytes from RECEPTION.rbpllc.com (192.168.7.150): icmp_seq=2 ttl=128 time=0.311 ms 64 bytes from RECEPTION.rbpllc.com (192.168.7.150): icmp_seq=3 ttl=128 time=0.309 ms ^C --- reception.rbpllc.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 0.309/1.262/3.166/1.346 ms Here is the dns entry: [13:23 nemesis:/home/david] # sdns $ORIGIN . $TTL 172800 ; 2 days rbpllc.com IN SOA bonza.rbpllc.com. root.bonza.rbpllc.com.
