[Samba 3.0] Rare foutmeldingen in /var/log/messages

[Nitroglycerine]

In mijn netwerkje heb ik voor centrale dataopslag een pc met fedora core 2 ingericht, en met behulp van samba deel ik de data op de fileserver met de rest van het netwerk. Dit gaat prima, beide pc's kunnen bij alle data met de juiste rechten, alleen kom ik wat aparte foutmeldingen tegen in /var/log/messages. Nu vraag ik me af of ik hier aandacht aan moet besteden, aangezien het werkt, maar toch wil ik het zekere voor het onzekere hebben en daarom vraag ik jullie advies.
Ik heb de verschillende zoektochten al uitgevoerd, google and GoT search, en daar krijg ik verschillende hits met verschillende mogelijke oorzaken. De pagina's die in een taal geschreven zijn die ik kan lezen heb ik aandachtig doorgenomen, en oplossingen die aangedragen worden uitgeprobeerd, maar niets heeft de foutmeldingen weg laten gaan.

Allereerst de foutmeldingen:

code:

Feb  6 02:37:39 fileserver smbd[1926]: [2005/02/06 02:37:39, 0] lib/util_sock.c:get_peer_addr(975)

Feb  6 02:37:39 fileserver smbd[1926]:   read_socket_data: recv failure for 4. Error = Verbinding door partner opnieuw ingesteld

deze meldingen komen ongeveer iedere 32 minuten terug.

De output van het commando findsmb -r <ipadres> geeft de volgende output:

code:

[root@fileserver root]# findsmb -r 192.168.0.20

                                *=DMB
                                +=LMB

Om te voorkomen dat iemand om de smb.conf gaat vragen:

# that connects

# NOTE2: You do NOT need these to allow workstations to change only

# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
; name resolve order = wins lmhosts bcast

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server

# WINS Server - Tells the NMBD components of Samba to be a WINS Client

;   wins server = w.x.y.z

# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one  WINS Server on the network. The default is NO.
;   wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.

Die onderste melding die je post heb ik zelf ook met enige regelmaat in de logs staan, maar daar heb ik nooit wat over kunnen ontdekken.
De bovenste melding doet vermoeden dat er iets niet goed gaat qua link tussen ip adres, dns naam en netbios naam. Wat ik zou doen is eerst eens nakijken of op alle systemen dns goed werkt. Staan alle systemen in DNS met zowel een forward als een reverse entry ? Als je geen lokale DNS gebruikt, heb je ze dan op alle systemen in /etc/hosts gezet ?
Als dat alles goed gaat, dan zou je eens na kunnen kijken het netbios name gebeuren goed staat. Je moet dan eens kijken naar 'name resolve order' in de smb.conf. Als daar in staat dat je wins gebruikt, dan moet er op je netwerk een wins server aktief zijn (of je laat samba dat doen door 'wins support' aan te zetten). Ook moet je op alle Windows werkstations dan je wins server bekend maken. Het alternatief is om geen wins te gebruiken, maar dan moet je dat wellicht expliciet uitzetten in de smb.conf
Ik hoop dat je hier wat mee kunt, en anders horen we het wel

Merci, ik ga ermee aan de slag.
