I have two servers aether and themis with dual NICs.
aether has the namespace 151 and 152 for its two NICs, while themis has the namespaces 153 and 154 for its two NICs.
I create a swarm on 151 of aether by
“ip netns exec 151 docker swarm init --advertise-addr 192.168.0.151” It shows
"Swarm initialized: current node (s5xb8j4nd3f49ygqbiowmd7rf) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-4m1y77gnxvfpkq5bhl23of4kby1mgfdo0yed8feiq2qjpk2ix3-35lo031qun46p75au62g93j0b 192.168.0.151:2377
To add a manager to this swarm, run ‘docker swarm join-token manager’ and follow the instructions."
Then when I use the above commannd on server themis, it does not work.The details is shown below:
When I type “docker swarm join --token SWMTKN-1-4m1y77gnxvfpkq5bhl23of4kby1mgfdo0yed8feiq2qjpk2ix3-35lo031qun46p75au62g93j0b 192.168.0.151:2377” on themis.
It shows
“Error response from daemon: Timeout was reached before node joined. The attempt to join the swarm will continue in the background. Use the “docker info” command to see the current swarm status of your node.”

When I add the namespace and use ip netns exec 154 docker swarm join --token SWMTKN-1-4m1y77gnxvfpkq5bhl23of4kby1mgfdo0yed8feiq2qjpk2ix3-35lo031qun46p75au62g93j0b 192.168.0.151:2377
on server themis. It is the same result as without namespce.
I am sure the network is fine. becasue when I ping, it works. When I use the below ping command on themis
root@vm1:~# ip netns exec 154 ping 192.168.0.151

When I tried with another two serves with single NIC for join the swarm. there is no problem.
I find solution from internet to diasble the firewall, and synchriozed the clock of the two servers, All do not work. And I tried telnet commmand, which is also not working. I think if telnet work. the join swarm should also work. But I can not know where is the problem and how to slove it
