Defining Remote Data Storage (NFS)
To use a NFS remote disk, click the Create NFS button to define it. Provide a name for the disk (in order to
identify it in the NAM user interface), enter the hostname of the server that has the remote disk, and provide
the directory as to where the capture files should be located.
Note(s):
• The NFS server must be configured to grant read and write access to the NAM in order for the NAM to
be able to store capture files on it. The following example shows how to set up an NFS directory
(/home/SomeUserName) on a Linux server for a NAM (at IP address 1.1.1.2) to store capture data.
• Locate a UID that has read and write access to the target NFS directory.
• For example, if the target NFS directory is /home/SomeUserName, open the /etc/password
file and search for a user entry that contains something like the following:
SomeUserName:x:503:503::/home/SomeUserName:/bin/tcsh
• In this example, the UID is 503.
• Edit the /etc/exports file and add a line like the following:
• /home/SomeUserName 1.1.1.2/255.255.255.255(rw,all_squash,anonuid=503)
• Activate the change: type: /usr/bin/exportfs -a
• If the NFS directory contains subdirectories that are not writable by the NAM, these subdirectories will
not be listed in NAM capture screens.
