I have a NFS server running on CentOS7 nfs-utils-1.3.0-0.21.el7.x86_64 Basically the oddity I am finding is as follows: server and client have same user and group with same uid's and gid's Client can only write to an exported folder if it "other/all" permission is set to write. I can get around this by using all_squash and setting the anon id's but this isn't really what I want. Am I missing a step that would allow this to work without all_squash. This is my setup: server0: where nfs-server is running client: where export is mounted Groups and uids all match on both machines [root@server0 ~]# groups user user : user common [root@server0 ~]# cat /etc/passwd | grep 'common\|^user' common:x:20000:20000:common:/home/common:/bin/bash user:x:1000:1000::/:/sbin/nologin [user@client ~] $ groups user user : user lp common [user@client ~] $ cat /etc/passwd | grep 'common\|^user' user:x:1000:1000:user:/home/user:/bin/bash common:x:20000:20000::/:/sbin/nologin server0 setup: [root@server0 ~]# ls -lr /test* drwxrwxrwx. 2 common common 6 Jan 7 16:05 /test_squash/chmod777 drwxrwxr-x. 2 common common 6 Jan 7 16:06 /test_squash/chmod775 drwxrwxrwx. 2 common common 6 Jan 7 16:05 /test/chmod777 drwxrwxr-x. 2 common common 6 Jan 7 16:05 /test/chmod775 [root@server0 ~]# cat /etc/exports /test 192.168.1.0/24(rw,async) /test_squash 192.168.1.0/24(rw,async,all_squash,anonuid=20000,anongid=20000) [root@server0 ~]# systemctl restart nfs-server client setup: [user@client ~] $ cat /etc/fstab | grep '^server' server0:/test /test nfs defaults 0 0 server0:/test_squash /test_squash nfs defaults 0 0 [user@client ~] $ sudo mount /test [user@client ~] $ sudo mount /test_squash [user@client ~] 1 $ touch /test_squash/chmod777/file [user@client ~] $ touch /test_squash/chmod775/file [user@client ~] $ touch /test/chmod777/file [user@client ~] $ touch /test/chmod775/file touch: cannot touch ‘/test/chmod775/file’: Permission denied [user@client ~] $ ls -lR /test* drwxrwxr-x. 2 common common 6 Jan 7 16:05 /test/chmod775 drwxrwxrwx. 2 common common 17 Jan 7 16:27 /test/chmod777 -rw-rw-r--. 1 user user 0 Jan 7 16:27 /test/chmod777/file drwxrwxr-x. 2 common common 17 Jan 7 16:28 /test_squash/chmod775 drwxrwxrwx. 2 common common 17 Jan 7 16:28 /test_squash/chmod777 -rw-rw-r--. 1 common common 0 Jan 7 16:28 /test_squash/chmod775/file -rw-rw-r--. 1 common common 0 Jan 7 16:28 /test_squash/chmod777/file So my real question is why cant user:user create a file in /test/chmod775 ?
