ACL on Ext2/3

• mit Option acl mounten: mount -o remount,acl /
• für dauerhafte Nutzung: sed 's/\(ext3\s\+\)/\1acl,/' /etc/fstab | diff /etc/fstab - und das patchen :).
• apt-get install acl
• getfacl und setfacl benutzen
  • setfacl -m u:huffna:r file gibt Benutzer huffna Leserechte
  • Achtung: Im Gegensatz zu AFS unterstützt Ext3-ACL auch für einzelne Dateien ACLs.

Aufsetzen von Evolver13 (Ubuntu 7.10 Beta i386)

Allgemeine Dienste

• ldap über auth-client => ganz isi
• autofs mit autofs config von evolver12

Windriver (9.01) für Darkwing

• in redist/linux_wrappers.c: pci_register_driver() statt pci_module_init()
• Packages: linux-headers-generic linux-source für "make prepare" Informationen bzw. modpost (=> postprocess module symbol versions :))
• in redist/configure aufrufen (nicht von unten make => versemmelt config)
• in redist/ make install => fertig
• chgrp F9_remote /dev/windrvr6; chmod 664 /dev/windrvr6
• in /etc/udev/rules.d/40-permissions.rules anhängen:

 # Windriver is very old... wrong register
 ACTION=="add", DEVPATH=="/bus/pci/drivers/windrvr6_pci", RUN+="/lib/mk_windrvr6.sh"
 ACTION=="remove", DEVPATH=="/bus/pci/drivers/windrvr6_pci", RUN+="/lib/mk_windrvr6.sh"

• dazu /lib/mk_windrvr6.sh:

 #! /bin/bash
 
 if [ "$ACTION" == "add" ]; then
   major=`grep -w windrvr6 /proc/devices | cut -f1 -d" "`
   mknod /dev/windrvr6 c $major 0 
   chgrp 1009 /dev/windrvr6
   chmod 664 /dev/windrvr6
 fi
 
 if [ "$ACTION" == "remove" ]; then
   rm /dev/windrvr6
 fi
