You will go on client and see which GID and UID are used by user tochange and group atlas numericly.
Then you will connect to NFS server and position youself in that folder and run
chown uid:gid .Xauthority_ori where UID and GID are numbers on NFS client for that user / group.
For instance if tochange user has 101 UID and atlas group has 101 GID, you will issue on NFS server
I'm kicking Unix questions out like Bruce Lee. So I'm copying a directory of files, in each directory I inevitablly get this:
I get that for usually the same set of directories/files in each folder. Is there a way to override this when copying files? (4 Replies)
I am trying to run chown and chmod from a script owned by root. The permissions are set to 4755 so that users can execute the script as root. However, when I run the script as a user other than root, I get "Operation not permitted" for both chown and chmod. Any ideas as to why this is? (6 Replies)

I executed command "chown -R xxx:xxx /" with user root... and it was too late when I found the mistake. Ownership of some files under the root directory had already become xxx:xxx.

nfsidmap(5) File Formats Manual nfsidmap(5)NAME
nfsidmap - The NFS idmapper upcall program
SYNOPSIS
nfsidmap [-v] [-t timeout] key desc
nfsidmap [-v] [-c]
nfsidmap [-v] [-u|-g|-r user]
DESCRIPTION
The file /usr/sbin/nfsidmap is used by the NFS idmapper to translate user and group ids into names, and to translate user and group names
into ids. Idmapper uses request-key to perform the upcall and cache the result. /usr/sbin/nfsidmap is called by /sbin/request-key, and
will perform the translation and initialize a key with the resulting information.
nfsidmap can also used to clear the keyring of all the keys or revoke one particular key. This is useful when the id mappings have failed
to due to a lookup error resulting in all the cached uids/gids to be set to the user id nobody.
OPTIONS -c Clear the keyring of all the keys.
-g user
Revoke the gid key of the given user.
-r user
Revoke both the uid and gid key of the given user.
-t timeout
Set the expiration timer, in seconds, on the key. The default is 600 seconds (10 mins).
-u user
Revoke the uid key of the given user.
-v Increases the verbosity of the output to syslog (can be specified multiple times).
CONFIGURING
The file /etc/request-key.conf will need to be modified so /sbin/request-key can properly direct the upcall. The following line should be
added before a call to keyctl negate:
create id_resolver * * /usr/sbin/nfsidmap -t 600 %k %d
This will direct all id_resolver requests to the program /usr/sbin/nfsidmap. The -t 600 defines how many seconds into the future the key
will expire. This is an optional parameter for /usr/sbin/nfsidmap and will default to 600 seconds when not specified.
The idmapper system uses four key descriptions:
uid: Find the UID for the given user
gid: Find the GID for the given group
user: Find the user name for the given UID
group: Find the group name for the given GID
You can choose to handle any of these individually, rather than using the generic upcall program. If you would like to use your own pro-
gram for a uid lookup then you would edit your request-key.conf so it looks similar to this:
create id_resolver uid:* * /some/other/program %k %d
create id_resolver * * /usr/sbin/nfsidmap %k %d
Notice that the new line was added above the line for the generic program. request-key will find the first matching line and run the cor-
responding program. In this case, /some/other/program will handle all uid lookups, and /usr/sbin/nfsidmap will handle gid, user, and group
lookups.
