Beim Zugriff auf Samba-Freigaben kommt es zu lockups von >= 30 sec

[Yasuo]

hi,

Beim Zugriff mit windows2000sp4 auf Samba-Freigaben (smbd, Debian Sarge gnu/linux) bekomme ich anfangs keinen Zugriff, was besonders nervend ist weil Netzlaufwerke eingehangen werden müssen.

Die WIndows-Clients sind 2 an der Zal und das Problem trat früher nicht auf.

Der Thread im WindowsXP-Forum "Beim Zugriff auf Samba-Freigaben kommt es zu lockups von bis zu 30 sec" scheint dasselbe Problem zu beschreiben, allerdings finde ich unter win2ksp4 keinen "WebClient"-Dienst den man abschalen könnte.

Gibt es den unter win2k oder ist mein Problem eher ein ganz anderes?

danke schonmal

Welches OS-Level hat der Samba-Server und wie erfolgt die Namensauflösung?

Vermeiden läßt sich dieser Effekt, indem man den Dienst 'WebClient' deaktiviert - ob dieser Dienst wirklich gebraucht wird, muß jeder Anwender für sich entscheiden, jedenfalls funktionieren danach die Samba-Freigaben wieder.

Unter Windows 2000 gibt es den Dienst "WebClient" nicht. Der Beitrag, auf den du dich beziehst und den Lemmi hier nochmal kopiert hat, steht daher auch nur in der Rubrik Windows XP.

hätt ja sein können.

>bekomme ich anfangs keinen Zugriff...
==>was heisst das jetzt genau, findet der Versuch gleich nach dem Booten des W2k-Rechners statt oder spaeter?

-tippe blind mal so auf nmbd

[Yasuo]

hi,

mit nmbd hab ich mich ehrlich gesagt garnicht beschäftigt...

Auf den Win2k-Clients sind Netzlaufwerka eingerichtet welche beim Hochfahren eingehangen werden.
Das erste Netzlaufwerk wird nicht eingehangen,

- klicke ich die Fehlermeldung sofort weg gibts beim nächsten Netzlaufwerk ebenfalls einen Fehler
- warte ich eine Minute und klicke die Meldung dann weg werden die restlichen laufwerke anstandslos eingehangen.


Mir hat sich der Verdacht aufgedrängt, dass sich beim updaten des Server-Systems (backports) die Konfigurationsdatei geändett hat - meine smb.conf hingegen wurde ja nicht geupdated weil modifiziert...

[linux-luder]

-versuche mal, auf den w2k-Maschinen den WINS fest einzutragen
(ich nehme mal an, das die Linux-Kiste auch den WINS macht)
-kannst ja mal die smdb.conf posten
(die Freigaben, Server und IP's kannste ja umbenennen)

-also meine Idee dabei ist, die w2k-PC's brauchen zu lange um zu checken, wer hier Masterbrowser ist
(schonmal das Mapping per IP-Adresse versucht?)

hi, wo trägt man den WINS manuel ein?

hier meine smb.conf:

   workgroup = lan

# server string is the equivalent of the NT Description field
   server string = %h server (Samba %v)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
;   wins support = no
   wins support = yes

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Put a capping on the size of the log files (in Kb).
   max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
;   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
