From Alessandro's Wiki
this is the protocol used for network file sharing in Apple systems (at leas for the latest ones)
server settings
- afpd.conf is the server configuration file, a backup server might look like this:
- -transall -ipaddr 192.168.0.10 -port 548 -noddp -uamlist uams_dhx.so,uams_dhx2.so -nozeroconf
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
- 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:
- 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/
UAM list
- usually in one of these dirs:
/usr/local/etc/netatalk/uams /usr/lib/atalk /usr/lib64/netatalk
ls /usr/lib/atalk/ uams_dhx2_pam.so uams_dhx2_passwd.so uams_dhx_pam.so uams_dhx_passwd.so uams_gss.so uams_guest.so uams_pam.so uams_passwd.so uams_randnum.so
Fedora 18
- a config file is located here:
/usr/libexec/netatalk/netatalk.sh
Volumes
path [name] [casefold:x] [options:z,l,j] \
[allow:a,@b,c,d] [deny:a,@b,c,d] [dbpath:path] [password:p] \
[rwlist:a,@b,c,d] [rolist:a,@b,c,d] [limitsize:value in bytes] \
[preexec:cmd] [root_preexec:cmd] [postexec:cmd] [root_postexec:cmd] \
[allowed_hosts:IPv4 address[/IPv4 netmask bits]] \
[denied_hosts:IPv4 address[/IPv4 netmask bits]] \
... more, see below ...
- defaults:
:DEFAULT: options:upriv,usedots,tm umask:002 dperm:0775 fperm:0664
- only user home with defaults:
~
- a time machine volume (user based) :
/backup/timemachine/$u/ "TimeMachine" options:usedots,upriv,noadouble,nohex,tm
- a share allowed only to some users and group "video"
/export/ingestion "Ingest" options:usedots,upriv,noadouble,nohex cnidscheme:cdb umask:002 dperm:0775 fperm:0664 allow:ale,jack,@video
- we need to create an hidden folder for AppleDB files:
mkdir /share/hidden chmod 700 /share/hidden dbpath:/share/hidden/.AppleDB/
- a read only share
/export/mirror/share "Share-snapshot" options:usedots,noadouble,nohex,ro,nocnidcache
problem solving
- 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.
find . -name \.AppleDouble -exec rm -rf {} \;
find . -name \.AppleDB -exec rm -rf {} \;
find . -name \.DS_Store -exec rm -rf {} \;
find . -name \.AppleDesktop -exec rm -rf {} \;
find . -name \.TemporaryItems -exec rm -rf {} \;
find . -name Network\ Trash\ Folder -exec rm -rf {} \;
find . -name Temporary\ Items -exec rm -rf {} \;
when having a mirror server
- DB becomes inconsistent due to path change (if different server) , the RSYNC command will need to exclude some files:
cat /mirror/excludes_afp .AppleDB/ .DS_Store .AppleDesktop/ .AppleDouble/ .TemporaryItems/ Temporary Items/ Network Trash Folder/
- example:
rsync -a --delete --delete-excluded --exclude-from=excludes_afp source_host:/dir/ /mirror/host/
- mediacluster excludes
.encoding.log .encoding.log.post.txt .encoding.log.p2.txt .stats.mbtree .stats ingestion/done/ virtual/
version 3
* Following config files are obsolete now: * afpd.conf, netatalk.conf, AppleVolumes.default and afp_ldap.conf * in favour of * /etc/afp.conf * Please convert your existing configs before you restart your daemon * The new AppleDouble default backend is appledouble = ea * Existing entries will be updated on access, but can do an offline * conversion with * dbd -ruve /path/to/Volume
variables
rules:
1) if you specify an unknown variable, it will not get converted.
2) if you specify a known variable, but that variable doesn't have
a value, it will get ignored.
the variables:
$b -> basename of path
$c -> client's ip or appletalk address
$d -> volume pathname on server
$f -> full name (whatever's in the gecos field)
$g -> group
$h -> hostname
$i -> client ip without tcp port or appletalk network
$s -> server name (can be the hostname)
$u -> username (if guest, it's whatever user guest is running as)
$v -> volume name (either ADEID_NAME or basename of path)
$z -> zone (may not exist)
$$ -> $
