8. The CN2510 will store the new firmware in its Flash ROM, and then restart the entire system, completing
the Firmware Upgrade procedure.
Remote RCP Upgrade
RCP (Remote Copy Program) is the Unix utility for copying files over the Ethernet. RCP allows transparent
copying of files between hosts, without the need to enter passwords. This can be done using the security
file
.rhosts
.
NOTE
The format of RCP is as follows:
rcp from to
The
from
and
to
arguments can either be specified as local files or remote files. To specify a remote file, use
the format:
user@hostname:filename
. If the remote login ID is identical to the local login ID, then
user@
can be omitted (i.e., only hostname:filename is required).
NOTE
The security file
.rhosts
is a plain text file that must reside in the local user’s home directory, and must be
owned by that user. This file identifies those users who are “equivalent” to the local user, and are given access
without needing to enter a password.
NOTE The file must contain at least a host, and if the login ID is different on the remote host, it must also contain the
login ID. This sample
.rhosts
file is for the user
john
on the host sun. The following three accounts are
considered “equivalent” accounts. The user has accounts on moxa1 and moxa3 with the same login ID, and has
an account on moxa2 as
johnwu
.

1. Login to your UNIX/LINUX host. For example, login to 203.67.8.22 as user “john”.
2. Copy the CN2510 firmware file, e.g., “CN2510.rom”, to the current directory.
3. Create a file named
.rhosts
in this directory. Enter CN2510’s IP address , e.g., 192.168.205.21, in
the
.rhosts
file, or enter CN2510’s domain name if it’s defined in your
/etc/hosts
file.
4. Telnet CN2510’s IP address.
