AFP guest on the iphone

Need to connect as guest at the moment - I need to work on the auth.

it also only uses the mtab backend, but for now it will be ok - we can read and write ok

Thanks to drudge of http://conceitedsoftware.com/iphone/site/

for asking about this, he has packaged most of the stuff on this site from start to end!

19:19 < drudge> how about something using the afp

[ ] afpd.tgz 05-Nov-2007 21:08 131K

21:28 < core> not bad from question to a working web page in two hours :)

So to the code

Extract the tar.gz file to /opt/iphone/afp/

Then just:

/opt/iphone/afp/startserver.sh

Should start the daemon

Then back over on the mac:

imac /afpd/ df -H /Volumes/test\ folder/
Filesystem                                Size   Used Avail Capacity Mounted on
afp_2nBRVm2nBRVm2nBRVm2nBRVm-1.2d000007   7.8G   7.2G   609M    92%    /Volumes/test folder

imac /afpd/ touch /Volumes/test\ folder/test

imac /afpd/ time dd if=/dev/zero of=/Volumes/test\ folder/test.dat bs=1024 count=100
100+0 records in

imac /afpd/ ls -ltra /Volumes/test\ folder/
total 256
drwxrwxrwx   2 core    core     264 Nov 5 20:36 Temporary Items

drwxrwxrwx   2 core    core     264 Nov 5 20:36 Network Trash Folder
drwxrwxrwt   7 root    admin    238 Nov 5 20:47 ..
-rwxrwxrwx   1 core    core       0 Nov 5 20:48 test
-rwxrwxrwx   1 core    core 102400 Nov 5 20:48 test.dat
drwxrwxrwx   7 core    core     264 Nov 5 20:48 .
-rwxrwxrwx   1 core    core    6148 Nov 5 20:48 .DS_Store

imac /afpd/ md5 /Volumes/test\ folder/test.dat
MD5 (/Volumes/test folder/test.dat) = 4c6426ac7ef186464ecbb0d81cbfcb1e

Back on the iphone:

# md5 /tmp/test/test.dat
4c6426ac7ef186464ecbb0d81cbfcb1e /tmp/test/test.dat

Result!

You can change the export by editing this file:

# cat /opt/iphone/afp/etc/netatalk/AppleVolumes.system

/tmp/test "test folder" cnidscheme:mtab

Remember that the daemon runs as nobody, so currently can only see chmod 777 areas :)

Real world speed tests, 2+ seconds for a 3.1MB file:

imac /Flood/ time cp 02\ Birdhouse\ in\ Your\ Soul.m4p /Volumes/iPhone\ Root/

imac /Flood/ du -h 02\ Birdhouse\ in\ Your\ Soul.m4p
