Hi all,
I am unable to create an SSH connection between our two FreeNAS boxes (Both on 11.3-U4.1). A static route has been created on host 1 and both connected interfaces show as active.
Have followed the documentation on how to create an SSH Connection and Keypair however when we try to "Discover Remote Host Key" the following error occurs:
(IP addresses and Hostnames obfuscated)
Below are the network settings for the NIC on host1:
Network settings for NIC on host2:
Output of netstat -rn host1
netstat -rn host2:
Both NICS are directly cabled together.
We have two other FreeNAS boxes that have the same setup as these two, and we have an SSH connection between these two for replication. It has a static route on host 1 as per the problematic NAS but I have noticed that in the routing table the gateway is set to "link#l" on the working NAS. When a static route is created via the gui on the NAS with the issue, the gateway in the routing table is set to host2 IP rather than "link#l".
/var/log/messages shows the following:
Any help would be much appreciated.
Thanks
Matt
