Setting up the ContentBridge
5. In the .ssh directory, copy the public key from the first ContentDirector:
scp <first ContentDirector>:.ssh/id_omauthchk.pub
6. Append the public key to the authorized_keys file as follows:
chmod 644 authorized_keys (if present)
cat id_omauthchk.pub >> authorized_keys
chmod 444 authorized_keys
Setting up the ContentBridge
Set up the ContentBridge.
1. Log in to the ContentBridge as root.
2. From
/opt/omclb/conf
, connect interactively to each public IP address of each of the
ContentDirector units using SSH, as follows:
ssh -l omauthchk <first public IP of first ContentDirector> /bin/hostname
ssh -l omauthchk <second public IP of first ContentDirector> /bin/hostname
ssh -l omauthchk <first public IP of second ContentDirector> /bin/hostname
ssh -l omauthchk <second public IP of second ContentDirector> /bin/hostname
3. Securely copy the private key from the first ContentDirector as follows:
scp omauthchk@<first ContentDirector>:.ssh/id_omauthchk /opt/omclb/conf/
id_omauthchk
4. Verify passwordless SSH access, as follows:
ssh -l omauthchk -i /opt/omclb/conf/id_omauthchk <first ContentDirector> /
bin/hostname
ssh -l omauthchk -i /opt/omclb/conf/id_omauthchk <second ContentDirector> /
bin/hostname
Configuring omauthremote.conf
Configure omauthremote.conf if you want authentication redundancy.
Before you begin
When setting up DNS entries for access to Harmonic MediaGrid, Harmonic recommends the following:
• Create a DNS entry for the Harmonic MediaGrid cluster with the public IP addresses of all
ContentDirector units.
• Create a DNS entry for each ContentDirector with the public IP addresses of the ContentDirector.
• Name each ContentDirector using <clustername>-1, <clustername>-2, etc. This is the default when
using
Configuration Assistant
.
• Use the DNS entry for the Harmonic MediaGrid cluster as the ContentDirector field of the Access
Configuration step of Initial Configuration.
• Initial Configuration sets up configuration files for Local User Access based on this recommendation.
1. Check the contents of
/etc/omauthremote.conf
and modify as needed for the site.
