Ticket #622 (Open)Thu Dec 07 19:58:18 UTC 2023

NFS doesn't behave correctly in respect of the permissions of a nfs share using user nobody.

Details by adr (12133):

host h5, debian nfs server exports example:
/data 192.168.99.0/24(rw,sync,no_subtree_check,all_squash,anonuid=1000,anongid=1000)

1000 is the user and group id of user adr in h5.

$ ls -lhd /data/stuff/tmp
drwxr-xr-x 2 adr adr 4.0K Dec 5 16:23 /data/stuff/tmp

On risc os:
*mount -host h5 h5 /data
*dir nfs::h5.stuff.tmp
*echo “hello” { > test }
Insufficient access

On h5 (debian) again:
$ ls lh /data/stuff/tmp
-rw——— 1 adr adr 0 Dec 7 2023 test,ffd

The file is created empty, but with the permissions set correctly.

Now, more weirdness… with edit If I make a file containing “hello” and save it to the share:

On h5:
$ ls lh /data/stuff/tmp
-rw——— 1 adr adr 0 Dec 7 2023 test,ffd
-———- 1 adr adr 5 Dec 5 16:59 TextFile

The file is created without permissions, but is not empty as before!
$ chmod u+rw /data/stuff/tmp/TextFile
$ cat /data/stuff/tmp/TextFile
hello

The only way I can open the file in risc os is changing the “other” permissions:
$ chmod o+wr /data/stuff/tmp/TextFile

Or if I set from risc os the Public permissions of the file.

Note that in sunfish nothing of this happens.
