I am following the instructions mentioned in
https://github.com/osrg/ryu/wiki/Test-OF-Config-with-LINC but after sending
the "Hello message" from Ryu controller the SSH connection gets terminated
with the following message.
On the Linc Switch Side -
[info] SSH connection with subsystem: enetconf_ssh terminated with state:
{state,<0.1402.0>,0,1,enetconf_fm_eom,{eom_parser,<<>>},linc_ofconfig}
It is able to make the SSH connection and send the Hello message but
getting terminated intermittently, I have taken the same sample sys.config
file mentioned in the link. Is there a way to get out of this situation
or at least see the full trace of error.
Log on Ryu Controller side -
