Honeycomb and ODL

Honeycomb can be managed using ODL as any NETCONF-enabled device. Please follow https://wiki.opendaylight.org/view/OpenDaylight_Controller:Config:Examples:Netconf for detailed instructions how to mount and connect to a NETCONF device

Troubleshooting

Unable to open SSH session due to invalid crypto configuration

If ODL fails to open ssh session due to InvalidAlgorithmParameterException, e.g.:

It probably means BouncyCastle provider is not properly configured on the ODL side. As a workaround start honeycomb with -Dorg.apache.sshd.registerBouncyCastle=false As a result 1024 bit DH group will be used for SSH key exchange.
