Connecting Clients to Harmonic MediaGrid Using ContentBridge
NOTE:
Before accessing the Harmonic MediaGrid, you must edit the ContentBridge configuration file to
support authentication and user access. See
Editing the ContentBridge Configuration File
in the
Harmonic
SystemManager User Guide
after completing the following for details.
The Harmonic MediaGrid file system is exported using a “share name.” This share name is created
using the Harmonic MediaGrid file system name and the account name used to access the file
system, as specified in the ContentBridge configuration file. See
Editing the ContentBridge
Configuration File
in the
Harmonic SystemManager User Guide
. The two are joined together
with an underscore to create the share name:
<FS_NAME>_<USERNAME>
For example, if the ContentBridge configuration file contained the following line:
CB MG1 mgfs2 user3 passwd4
Then the share name would be “mgfs2_user3”.
In the following sections, replace <SHARE_NAME> with the appropriately constructed share
name.
Using FTP on a Windows Client
To use FTP:
1. Start an FTP application.
2. Enter the domain name of the ContentBridge.
3. Enter a valid user name and password.
The user name and password must exist in the ContentBridge configuration file. See
Editing the
ContentBridge Configuration File
in the
Harmonic SystemManager User Guide
for more
information. The user name and password must also be valid for the Harmonic MediaGrid system.
4. The FTP client is placed in a directory two levels above the actual Harmonic MediaGrid mount
point. Change to the following directory to access the Harmonic MediaGrid files, where
FS_NAME
is the name of the file system:
/omfs/
<FS_NAME>
NOTE:
The maximum path length for any file in a Harmonic MediaGrid file system is 1025 characters
(1024 + 1 for the NULL character).
Using FTP in a Local User Authentication Domain
You are only allowed to have one native mount per High Bandwidth ContentBridge.
ContentBridge mount users (by default) start in (root directory) a directory that is 2 levels
above the MediaGrid. You must change directory into the Harmonic MediaGrid to avoid
accidentally writing data to the High Bandwidth ContentBridge (local Linux system). The only
way to avoid this when using a ContentBridge mount is to specify the "ftphome" option.
PAM Authentication requires a connection to the ContentDirector to validate the user.
When neither ContentBridge or NATIVE are specified, FTP connections for existing LUA users
are rejected with
530 Login incorrect
When NATIVE mount is specified, FTP connection for all LUA users will start (root directory)
inside of the Harmonic MediaGrid root filesystem directory
