mount
 

when i am trying to mount,i am getting error can any one help me

mount: Can't find 10.7.146.11:/home/saritha/mntgnash in /etc/fstab

You either need to add an entry to fstab (obviously), or specify the mount point, options etc on the command line.

actually i want to mount a directory from one linux system to another linux system,i also exported in /etc /exports with the same path /home/sari....,

so can u help me how to specify the mount point, options etc on the command line.

mount -t nfs share to mount mount point -o options. Seriously, did you not bother reading the man page for mount?
