want to restrict both normal users and root user inside LXD container “hypervisor” from viewing and using dmesg command output. How do I prevent non-root (unprivileged) Linux users from viewing the Linux kernel’s log buffer? Can Linux prevent unprivileged users from viewing dmesg command output?
‘ve netapp NFS server with /data3 as shared directory. I type the following command at Ubuntu Linux to mount the NFS server:
mount fs2:/data3 /nfs/
mount 192.168.1.100:/data3 /nfs/
But I’m getting an error which read as follows:
mount: wrong fs type, bad option, bad superblock on fs2:/data3,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog – try
dmesg | tail or so
How do I fix this problem?
