Hallo zusammen,
kurze Info zu meiner Person da ich mich noch nirgendwo vorgestellt habe:
Ich heisse Markus, bin 30 Jahre, habe diverse Erfahrungen mit verschiedenen Linux-derivaten erlangt, zumeist unter Mandrake / Mandriva.
Bin danach mal auf Debian Etch umgestiegen aber hab dann ganz schnell zu Ubuntu gewechselt.
Ich setze Linux zumeist nur als Arbeitstier ein, sei es als Fileserver, oder als Plattform zum testen von Websites.
Infos zu meinem Problem:
Hardwareseite:
Ich habe bei mir in der Firma einen kleinen Ubuntu Server aufgesetzt, der im Firmennetzwerk die
Aufgabe eines Datenservers übernimmt. Als Version habe ich dabei die aktuelle 8.04 Serverversion installiert,
natürlich nur mit Bash als Oberfläche. Netzwerk an sich funktioniert einwandfrei, habe alle Rechner die GiBit Anschluß haben direkt am
Switch hängen. Baulich bedingt habe ich aber nochmal zwei Switche per uplink angebunden, um etwas entferntere Büros zu versorgen.
Von folgenden Bedingungen weiß ich:
Die Interlink Geschwindigkeit innerhalb der per uplink angebundenen Switche ist nur GiBit. Hier kann es schon mal eng werden.
Die Interlink Geschwindigkeit des Hauptswitches beträgt irgendwas um die 30 GiBit. Sollte also ausreichen.
Für nähere Infos hab ich euch mal nen PDF hier angebunden, da ist mein Netzwerk drauf zu sehen.
Nun die Softwareseite:
Wie schon gesagt, Ubuntu 8.04 Server, Bash als Oberfläche, keine Perepherie am Server, nur Zugriff per SSH über Putty.
Aktuelle Version vom Samba-Server 3.0.28a (gestern noch geupdatet)
Problem:
Im Netzwerk würde ich gerne herausbekommen wie die Dateizugriffe erfolgen. Eventuell als kleine Statistik, so dass ich dann halt passend dazu
die SMB-Configuration noch anpassen könnte. Gerade viele zugriffe auf kleine Dateien scheinen mir etwas träge zu sein im Netzwerk, wohingegen ich bei großen
Dateien auf über 80 MB/sec komme... Also mein Hauptproblem läuft quasi auf ein Benchmarking heraus, um verschiedene Optionen zu testen und das beste aus dem SMB-Server herraus zu holen.
Hat sowas schon mal jemand versucht / gemacht?
Hat jemand vieleicht ne idee wie ich das bewerkstelligen kann?
anbei jetzt mal noch die SMB Configuration, ich habe die Kommentarzeilen mal drin gelassen, vieleicht entdeckt ja noch wer ne
verbesserungsmöglichkeit.
[smb.conf]

#### Networking ####

# This tells Samba to use a separate log file for each machine
# that connects

# Cap the size of the individual log files (in KiB).

# 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

####### Authentication #######
# "security = user" is always a good idea. This will require a Unix account

# in the samba-doc package for details.

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
