[Bug 1509867] [NEW] docker network connection only working after daemon restart

[Viktor Pal]

Public bug reported:

I have just upgraded to Ubuntu 15.10 and realized when I trie to ssh into my container I get the following error message:
ssh_exchange_identification: read: Connection reset by peer
Sometimes I get this message immediately sometimes it takes longer.

It looks like this using telenet:
#####################
$ telnet 127.0.0.1 55555
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

Connection closed by foreign host.
#####################
No ssh banner.

This is resolved by restarting the docker daemon and starting the container again.
This is completely reproducible I just have to restart my desktop and  after the restart start the container and ssh connection always fails and after restarting the daemon it always succeeds.

Just restarting the container doesn't help, I have to restart the daemon
to solve the problem.
