Streaming video between K2 systems
To provide the required name resolution for the FTP/streaming network, in the hosts
file each system that is a transfer source/destination has its host name listed twice:
once for the control network and once for the FTP/streaming network. The host name
for the streaming network has the extension “_he0” after the name. The K2 systems
use this information to keep the FTP/streaming traffic separate from the control
traffic.
For FTP transfers to/from a K2 SAN, transfers go to/from K2 Media Servers that have
the role of FTP server. No transfers go directly to/from the shared storage K2 clients
that are on the K2 SAN. So in the hosts file, you must add the “he_0” extension to a
K2 Media Server hostname and associate that hostname with the K2 Media Server’s
FTP/streaming network IP address.
To see an example, refer to the “Sample K2 client configuration and hosts file” on
page 50 . Otherwise, proceed with the following steps to set up your hosts file.
On each K2 system, set up the hosts file as follows:
1. If you have not already done so, disable the write filter. Refer to “Disabling the
write filter” on page 156 .
2. Open the following file using Notepad or some other text editor.
c:\WINDOWS\system32\drivers\etc\hosts
3. Enter text in two lines for each K2 system that is a transfer source/destination.
a. Type the IP address for the control network, then use the TAB key or Space bar
to insert a few spaces.
b. Type the machine name, such as K2-Client. This sets up the host file for resolving
the machine name on the control network. The machine name must not have any
spaces in it.
c. On the next line, type the IP address for the FTP/streaming network, then use the
TAB key or Space bar to insert a few spaces.
d. Type the machine name followed by the characters “_he0”. Be sure to use the
zero character, not the letter ‘o’. Refer to the following example:
00.16.42.10 K2-Client
00.0.0.10 K2-Client_he0
4. For systems that are not a transfer source/destination, the second line (for the FTP/
streaming network) is not required.
5. If there are UIM systems on the FTP/streaming network, make sure you follow the
UIM naming conventions. Refer to the UIM Instruction Manual.
6. Once you have added the host names for the all the systems on the networks for
which the host file provides name resolution, save the file and exit the text editor.
7. Copy the hosts file onto all the other machines to save you editing it again.
Remember to disable the write filter on all K2 Summit Production Clients.
8. Enable the write filter. Refer to “Enabling the write filter” on page 156 .
9. Proceed to “Add host names to AppCenter to enable streaming” .
