AFP

this is the protocol used for network file sharing in Apple systems (at leas for the latest ones)

server settings

user permissions

• in /etc/netatalk/AppleVolumes.default we can set the file permissions to use for each service.
  • example: we have a network with an all-users group and we want them to be able to overwrite each-other files. Others can read:
    • umask:002
    • dperm:0775
    • fperm:0664
  • default linux behaviour, with read only to group users.
    • umask:022
    • dperm:0755
    • fperm:0644

• the complete line:

/directory/shared/ "Awesome Share" options:usedots,upriv,noadouble,nohex cnidscheme:cdb umask:002 dperm:0775 fperm:0664

veto files

• this option hides the objects specified between slashes

veto: recycled/desktop.ini/Folder Settings/

problem solving

Finder "stucks" on connect to share

• in the log you'll see the server stopping after a message like this:

afpd[]: Setting uid/gid to 100/100

• the solution in my case was:
  • stop the server
  • remove the Finder database file .AppleDB
  • restart server.
