Installed different distro in Vagrant. Now can't SSH into MySQL - ssh

I was using Ubuntu precise32 and switched to 14.04. I use Jeffrey Way's setup (https://github.com/JeffreyWay/Vagrant-Setup) and that works. I can do 'vagrant ssh' and log in, and log into root with username/password root/root.
When I try using Sequel Pro for a GUI, I get the following error:

What am I doing incorrectly here? Here's a screenshot of my setup in Sequel Pro.

I found my answer. I had to remove the entry already in my known_hosts file for 127.0.0.1 and it worked after that.

Unable to get SSH connections working on On Premise GitLab Instance

I have deployed an on premise instance of GitLab (using the steps described in https://docs.gitlab.com/ee/install/docker.html), created a user, generated a key pair and uploaded the public key by following the steps in https://docs.gitlab.com/ee/ssh/.
The private key is located in directory ~/.ssh with 600 permissions, and file ~/.ssh/config is as follows:
Host gitlab.mycompany.com
Hostname gitlab.mycompany.com
User myusername
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes
TCPKeepAlive yes
However, I'm getting error 'Permission denied (publickey)' when trying to establish an SSH connection:

I believe the issue is on the server side because I was able to establish a successful connection to gitlab.com using the same key pair.
Any ideas on how to troubleshoot this issue?
Additional Details
Something I did not mention in my initial description of the issue is that GitLab was deployed as a container, so I'm thinking what might be happening is that the host is reachable over port 22, but it might not be re-directing to the GitLab container.
Check /var/log/auth.log on your Gitlab host. It tends to have more details on authentication errors. Look for sshd entries.
I managed to resolve the issue :)
Turns out, I missed the --publish 22:22 directive when creating the container.
sudo docker run --detach \
--hostname gitlab.mycompany.com \
--publish 443:443 --publish 80:80 --publish 22:22 \
--name gitlab \
--restart always \
--volume $GITLAB_HOME/config:/etc/gitlab:Z \
--volume $GITLAB_HOME/logs:/var/log/gitlab:Z \
--volume $GITLAB_HOME/data:/var/opt/gitlab:Z \
gitlab/gitlab-ee:latest
The resolution was:
Stop the container
$ sudo docker stop gitlab
Turn off docker
$ sudo systemctl stop docker
Edit file /var/lib/docker/containers/[container id]/hostconfig.json to change PortBindings from
"PortBindings":{"443/tcp":[{"HostIp":"","HostPort":"443"}],"80/tcp":[{"HostIp":"","HostPort":"80"}]}
to
"PortBindings":{"443/tcp":[{"HostIp":"","HostPort":"443"}],"80/tcp":[{"HostIp":"","HostPort":"80"}],"2222/tcp":[{"HostIp":"","HostPort":"22"}]}
(I opted to use port 2222 instead)
Start up docker
$ sudo systemctl start docker
Start the container
$ sudo docker start gitlab
The above allowed me to successfully connect:
$ ssh -T git#gitlab.mycompany.com -p 2222
Enter passphrase for key '/home/<username>/.ssh/id_rsa':
Welcome to GitLab, #<username>!

Your scp is connecting somewhere else and since you obfuscated the IPs/addresses I have no idea if that is intention or that the it really does.
The scp is parsing your files and probably found some : character in your file name (first guess about # was false) and parses that filename as host:path? Give it a try with only one of the files, post the real name of files.
Or rather use sftp. It does not care about the syntax on command line. Just sftp your host and then:
cd folder1
put my_file file2

unable to get agent forwarding on vagrant working

Despite my best efforts, I cannot seem to get agent forwarding on Vagrant. I'm running OS X with the following vagrant/virtualbox combo:
[chrisshorrock:~]$ vboxwebsrv --version

Firstly - in my vagrant file I have
config.ssh.forward_agent = true
I've confirmed that my key (on my os x box) is added to my ssh agent with:
ssh-add -L
My ~/.ssh/config file contains the following:
Host 127.0.0.1
ForwardAgent yes
I can connect to outside servers, and have confirmed that something like:
ssh -T git#github.com
Works properly (both locally and remotely indicating that ssh agent forwarding functionality seems correct on the OS X box), however, when I connect to my vagrant instance, I have no such luck:

The culprit here was the ssh-agent helper for oh-my-zsh.

ssh password-less login to localhost

I am trying to setup password-less login into my localhost for a distributed computing tutorial. (I've set it up successfully for multiple remote hosts.) I went through the normal steps of generating an rsa key and appending the public key to authorized_keys but I am still prompted for a password. I've also enabled RSAAuthentication and PubKeyAuthentication in /etc/ssh_config. Following other suggestions I've seen, I tried:
chmod go-w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
But the problem persists.

Any suggestions? I'm running OSX 10.8.
Since you seem to have multiple keys I would assign the specific key to a specific connection in ~/.ssh/config.
Example:
Host local
HostName 127.0.0.1
Port 22
User your_username
IdentityFile ~/.ssh/your_key-id_rsa
Then just try to ssh local.
I had same problem. I checked the system passwd and group files, and discovered that my user and group was not present. To build this files (my user was a domain user) I need to run two commands at cygwin shell:
mkpasswd -l -d > /etc/passwd
mkgroup -l -d > /etc/group
After that, ssh works fine!
Elvys Borges
It looks like you are using protocol version 2.0 when connecting to localhost, so try moving authorized_keys to authorized_keys2.
Source: this post explains the difference between the two keys files.
I was at my wits end... I was under the mistaken impression ssh-copy-id was a Linux-only utility. Finally I just swallowed my pride and typed the command is the macOS Terminal and it worked!
ssh-copy-id me#sshd-server
I don't know what magic ssh-copy-id does, but it just worked. I was able to log in without a password successfully with the simple command:
ssh me#sshd-server
I had zero luck with cat id_rsa.pub >> ~/.ssh/authorized_hosts. Every time I tried ssh'ing to the server it just kept asking me for the passphrase. This is with the correct 600 permission on authorized_hosts and 700 on ~/.ssh.

ssh localhost connection closed by 127.0.0.1?

So, I'm going through this tutorial (Running Hadoop on windows using cygwin...) to setup hadoop on my WINDOWS (please don't ask why I would use Linux). So I got to this point that I need to SSH to my localhost and test the SSH using Cygwin, but it closes the connection and says:
Connection closed by 127.0.0.1
I've googled a lot but couldn't find any proper answer for my problem.
P.S.: I'm running cygwin on Windows 7 professional x64
any idea?

When you installed Cygwin and ran ssh-host-config, you might have created user cyg_server. So when you are connecting to ssh, you need to use the user cyg_server#localhost.
When you run ssh with that user, it will ask you for the password that you provided when you ran ssh-host-config.
$ ssh cyg_server#localhost
cyg_server#localhost's password:
Last login: Mon Dec 31 01:14:44 2012 from ::1
cyg_server#polorumpus ~
$
I hope it will be useful.
It looks like the key isn't being accepted. Check that /home/Soroush/.ssh/id_rsa.pub has been added to /home/Soroush/.ssh/authorized_keys
I would also check that
RSAAuthentication yes is set in /etc/ssh/sshd_config
I had to do these to fix the problem:
chown <USERNAME> /var/log/sshd.log
chown -R <USERNAME> /var/empty
chown <USERNAME> /etc/ssh*
chmod 755 /var/empty
chmod 644 /var/log/sshd.log
Note that the is my desired user name, not cyg_server.
I Found this post relating to my issue, but it turned out that my cyg_server account did not have administrator privilege.
I had the same problem, and it was generated by Putty authentication agent (Pageant): it was running with a private key. For some reason, it tried to use it to connect to localhost. If I closed Pageant (or removed the key), I could ssh to localhost.
But as I wanted to have Pageant running (to be a client of other ssh servers), I managed to modify the local sshd service, so that it 'ignored' in some way Pageant, to accept connections:
Modify /etc/ssh/sshd_config:
PubkeyAuthentication no
Now, it works
I had to use the 64-bit version of Cygwin to get this to work.
