Testing ssh functionality on my Mac and wondering why SSH into localhost just with the command:
$ ssh localhost
Prompts me for a password, and responds with
Password:
localhost: Authentication failed.
on the first attempt (after entering correct local password), and consistently follows up with more prompts if I enter the wrong password or nothing:
$ ssh localhost
Password:
Password:
Password:
squid#localhost's password:
Received disconnect from ::1 port 22:2: Too many authentication failures
Authentication failed.
The behavior is different if I enter the right password, so I know my password is correct. But why would authentication still fail? Please help!
UPDATE : Figured it out. It's a setting with local file sharing. Not sure why but out of the box configurations don't allow for an ssh into localhost. To fix: Open System Preferences -> Sharing -> Check Remote Login (make sure your user is included)

We received the following error when connecting to the server:
WHEN CONNECTING AS "root" USER:
with Digitalocean droplet
Error Output
Server Disconnected
We had trouble connecting to your server. Typically, this means there is a problem with the SSH keys on the server. Or, your server may be prompting for a password when Forge attempts to SSH in as the root user.
Recently reset the root password? If you have recently reset your root password via the DigitalOcean control card, this will break Forge's access to your server. You must SSH into your server and set a new password for the root user.
We received the following error when connecting to the server:
WHEN CONNECTING AS "root" USER:
Please make sure that the following SSH key is placed in both the /home/forge/.ssh/authorized_keys file and the /root/.ssh/authorized_keys file on your server.
good day.
I generated ssh-keygen via user not in root and I copied it to my remote server. I can ssh the remote server without asking for a password in the user. As far as I read from the documentations it needs to have generated ssh-key in root in order to run commands like this:
ansible all -m ping
Is there a way that I can get to this successfully without using root?
For now, I get this error:
"msg": "Failed to connect to the host via ssh: <username>#192.x.y.z: Permission denied (publickey,password).",
Hi~~ I'm doing the official tutorial from the follwoing link.
My system is windows 10, I'm using VirtualBox 6.0 and downloaded the latest sandbox.
The following are what I did step by setp:
(1) Boot up: I cannot upload image but the information on boot up are as follow:
Hostname: gpdb-sandbox.localdomain
IP: 192.168.5.138
GPDB Admin: gpadmin
GPDB Password: pivotal
Tutorial User: gpuser
Tutorial User Password: pivotal
(2) Navigate to pg_hba.conf and add "host all all 0.0.0.0/0 md5" to the last of it
(3) Navigate to postgresql.conf and add "listen_addresses = '*'" to it
(4) Then I loged in the OS and run the following commmand
./start_all.sh
(5) Then I opened a cmd.exe from my windows and run
psql -U gpadmin -h 192.168.5.138 -p 5432 postgres
(6) The program replies with request for password, then I typed in "pivotal"
And then the program replies with an authentication failure. Can anyone help me with that so that I can start the first step of the tutorial??
Thanks a lot!
No need to type all the parameters if you are connecting to database from the sand box terminal.
just do psql and press enter you will be connected to gpadmin database.
if you changeor add any entries in pg_hba.conf please relode the configurations by running below command.
gpstop -u
I ssh into a server with the following:
ssh -g -L5912:server:5912 user#host
It goes through, and I can access my files on the other server through the command line (meaning I can connect to the server, it is my vnc viewer that is failing!) but when I try to open my vnc viewer (RealVNC) and connect to localhost:12 i get the following error message in the vnc viewer application:
The connection closed unexpectedly.
Additionally in the original command line shell i get:
channel 3: open failed: connect failed: No route to host
I've tried switching to different ports and even checked out other posts on the same error message but the problem is i don't really understand them... ssh tunnels are still relatively new to me so i don't really know what im doing. Any help would be greatly appreciated. Thanks!
You're trying to setup a port forwarding, this may fail because of many reasons:
SSH port forwarding not enabled in the host
Check SSH server in the host if AllowTcpForwarding is enabled:
$ grep AllowTcpForwarding /etc/ssh/sshd_config
AllowTcpForwarding yes
Typically, it's commented out. Uncomment and restart the sshd.
No connection between the host and server over port 5912
SSH to the host and try:
$ telnet server 5912
Connected to server.
Escape character is '^]'.
Finally, does the server listen on 5912?
Similarly, as above, but from the server - go there and try telnet server 5912.
Best regards,

In my case it was the port forwarding rule I had set in Putty.
Please make sure you enter the correct hostname when defining the rule in Putty. I changed
localhost:5903
with
myserver:5903
and it worked...
I'm trying to get Hadoop's Pseudo-Distributed Operation example (http://hadoop.apache.org/common/docs/stable/single_node_setup.html) to work on OS X Lion, but am having trouble getting the ssh to work without a passphrase.
The instructions say the following:
Setup passphraseless ssh
Now check that you can ssh to the localhost without a passphrase: $
ssh localhost
I'm getting connection refused:
archos:hadoop-0.20.203.0 travis$ ssh localhost
ssh: connect to host localhost port 22: Connection refused
If you cannot ssh to localhost without a passphrase, execute the
following commands:
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
After this step I am still getting connection refused. Any ideas???
Sounds like you don't have SSH enabled. Should be in the network settings control panel somewhere.
You go to "System Preferences > Sharing > Remote Access" and there's a list of authorized users. Change it to "All Users".
That's solves this problem.
Check the permissions on your .ssh directory. Some ssh implementations require that the directory be chmod 700. Otherwise, they just ignore it.
Also, check the output of
ssh -v localhost
to see how the ssh client is trying to connect. The output is very detailed, and will help you decide if it's an authentication problem.
I had the same issue.
Please check if the ssh server is running or not.
If yes, open the /etc/init.d/ssh_config and /etc/init.d/sshd_config files. The issue is that the server is running on a different port and the client is pointing to different port.
Before this please ensure that openssh-server and client are installed.
I had the same problem and i solved it the following manner :
SSH is activated.
ssh -v localhost (as stated by Herko)
In the ouput, i identified that the authentication method by DSA is not supported.
debug1: Skipping ssh-dss key /Users/john/.ssh/id_dsa - not in PubkeyAcceptedKeyTypes
I simply re-generate an ECDSA keys and remove the DSA key pairs.
After the keys generation, the procedure given on Hadoop documentation holds.
Therefore, it is important to check, if the authentication method is supported by the Openssh configuration.
