UC-7110 Series User’s Manual Configuring UC-7110
4-10
1. First, the NFS server must open an export directory and allow access to the IP address. Edit
the file “/etc/exports” on your Linux PC, and then run the NFS daemon. The following
example gives one possibility (refer to the NFS-HOWTO document at
http://nfs.sourceforge.net/nfs-howto/server.html ):
/home/usr 192.168.3.1 (rw,no_root_squash,no_all_squash)
2. UC-7110 must run the “portmap” utility. This program is enabled by default in the “/etc/rc”
file. Use the following command to mount the remote NFS server:
/>mount –t nfs <remote-ip>:<remote-export-directory>
<local-directory>
Upgrading the Kernel & Root File System
UC-7110 combines the kernel and root file system into the file uc7110-1.x.x.bin, which can be
downloaded from
www.moxa.com . You must first download this file to your PC, and then use
Console Terminal or Telnet Console to copy the file to UC-7110.
You can save this file to the UC-7110’s RAM disk, and then upgrade the kernel and root file
system. In what follows, we give a step by step example.
To enable the RAM disk, use the commands given below:
/>upramdisk
/>cd ramdisk
Use the built-in FTP client to download the uc7110-1.x.x.bin file from the PC.
/ramdisk>ftp <destination PC’s IP>
