running knife gives me double @ at the address part

Question

I don't know what is wrong with my settting:

siegfried@ubuntu:~/chef-repo$ knife ssh -a ipaddress 'name:chefnode' 'uptime'        

WARNING: Failed to connect to  -- Net::SSH::AuthenticationFailed: Authentication       failed for user [email protected]@192.168.1.73

failed for user [email protected]@192.168.1.73

There is a double @ in it. I totally have no idea how to fix it.

Answer 1

Not yet 100% sure what is going on but I believe the double "@" is just a print message (it is not actually trying to connect to that host). The double comes from:

# net-ssh-multi-1.2.0/lib/net/ssh/multi/server.rb
#
192       rescue Net::SSH::AuthenticationFailed => error
193         raise Net::SSH::AuthenticationFailed.new("#{error.message}@dude#{host}")
194       end

I have so cleverly added the word "dude" here which we can see in my output:

user@ubuntu:~/chef-repo$ knife ssh 'name:ep1' uptime
WARNING: Failed to connect to ep1.site.com -- Net::SSH::AuthenticationFailed: Authentication failed for user [email protected]@dudeep1.site.com

Seems like some type of a bug but not our problem. I'm going to keep debugging but probably something along the lines of @Carolyn's suggestion https://stackoverflow.com/a/22439127/851145.

Update

Indeed the double "@" was a complete red herring. For me the solution was to simply specify the password with --ssh-password (I have not installed keys on the remote endpoint).

knife ssh 'name:ep1' uptime --ssh-password password

So probably an issue with key or password. -VV is your friend.

Answer 2

In order to resolve this issue, first check the client node and check whether root access is provided. Check the file /etc/ssh/sshd_config file and change the permitrootaccess to Yes. Stop ssh and the again start

or else use --sudo along with any username and password in the command
