Failed to pass credentials to nfs mount

The name of the pictureThe name of the pictureThe name of the pictureClash Royale CLAN TAG#URR8PPP

I am running CentOS 7 and need to mount an NFS share which is protected by credentials. I have read the nfs, mount, mount.nfs manuals and can't find the right options that work! I think the right options are 'user' and 'pass', but I've tried 'username' and 'password' and everything inbetween, but I get:



mount -t nfs -o user=root,pass=mypass lserver:/root /mnt/d0
mount.nfs: an incorrect mount option was specified


Can someone tell me the right syntax/options to make this work? (It really shouldn't be this hard)

          Specifying username and password are options for cifs (samba), but not nfs. According to this CentOS Documentation:




          NFS controls who can mount an exported file system based on the host making the mount request, not the user that actually uses the file system. Hosts must be given explicit rights to mount the exported file system. Access control is not possible for users, other than through file and directory permissions.

          • I missed that! But why is 'user' a valid parameter for NFS mounts?

            Where do you see that? There is no user option in man mount.nfs.

          • When I try adding parameters, they all give invalid option errors, but the 'user' option does NOT generate an invalid option error

          The user option is related to allow any users on your system allowed to mount the file system. See the "non-superuser mounts" of man mount

            sudo mount -t nfs -O user=root,pass=mypass lserver:/root /mnt/d0




            Notice that the 'O' is a capital letter.

              This works under CentOS



              mount.cifs //192.168.0.123/myshare /mnt/myshare -o user=myuser


              (it asks for the password - you can add it on the commandline probably via pass=)



              Run this by itself to see all the options:



              mount.cifs



              Usage: mount.cifs -o



              Mount the remote target, specified as a UNC name, to a local
              directory.



              Options:
              user=
              pass=
              dom=



              Less commonly used options:
              credentials=,guest,perm,noperm,setuids,nosetuids,rw,ro,
              sep=,iocharset=,suid,nosuid,exec,noexec,serverino,
              mapchars,nomapchars,nolock,servernetbiosname=
              directio,nounix,cifsacl,sec=,sign,fsc



              Options not needed for servers supporting CIFS Unix extensions
              (e.g. unneeded for mounts to most Samba versions):
              uid=,gid=,dir_mode=,file_mode=,sfu



              Rarely used options:
              port=,rsize=,wsize=,unc=,ip=,
              dev,nodev,nouser_xattr,netbiosname=,hard,soft,intr,
              nointr,ignorecase,noposixpaths,noacl,prefixpath=,nobrl



              Options are described in more detail in the manual page
              man 8 mount.cifs



              To display the version number of the mount helper:
              mount.cifs -V
