UC-7420/7410 User’s Manual Managing Communication
4-19
async
The async option instructs the server to lie to the client, telling the client that all data has been
written to the stable storage.
Example 1
/tmp *(rw,no_root_squash)
In this example, UC-7420/7410 shares the /tmp directory to everyone, gives everyone both read
and write authority. The root user on the client machine will have the same level of access to files
on the system as the root on the server.
Example 2
/home/public 192.168.0.0/24(rw) *(ro)
In this example, UC-7420/7410 shares the directory /home/public to a local network
192.168.0.0/24, with read and write authority. NFS clients can just read /home/public; they do not
have write authority.
Example 3
/home/test 192.168.3.100(rw)
In this example, UC-7420/7410 shares the directory /home/test to an NFS Client 192.168.3.100,
with both read and write authority.
NOTE After editing the NFS Server configuration file, remember to use the following command to
restart and activate the NFS server.
/etc/init.d/nfs-user-server restart
Setting up UC-7420/7410 as an NFS Client
The following procedure is used to mount a remote NFS Server.
1. Scan the NFS Server’s shared directory.
2. Establish a mount point on the NFS Client site.
3. Mount the remote directory to a local directory.
Step 1:
#showmount –e HOST
showmount: Show the mount information for an NFS Server.
-e: Show the NFS Server’s export list.
HOST: IP address or DNS address.
Steps 2 & 3:
#mkdir –p /home/nfs/public
#mount –t nfs NFS_Server(IP):/directory /mount/point
Example
: #mount –t nfs 192.168.3.100/home/public /home/nfs/public
Mail
smtpclient is a minimal SMTP client that takes an email message body and passes it on to an
SMTP server. It is suitable for applications that use email to send alert messages or important logs
to a specific user.
