Press the following three keys:

1. Enter
1. ~ (tilde)
1. . (period)

This is the &quot;disconnect&quot; function as described in the `ESCAPE CHARACTERS` section of the `ssh` `man` page.

In [this post][1], [geekosaur][2] suggests we use the escape sequences as follows: &quot;To kill the current session hit subsequently &lt;kbd&gt;Enter ↵&lt;/kbd&gt;, &lt;kbd&gt;~&lt;/kbd&gt;, &lt;kbd&gt;.&lt;/kbd&gt;.

More of these escape sequences can be listed with &lt;kbd&gt;Enter ↵&lt;/kbd&gt;, &lt;kbd&gt;~&lt;/kbd&gt;, &lt;kbd&gt;?&lt;/kbd&gt;:

    Supported escape sequences:
      ~.  - terminate session
      ~B  - send a BREAK to the remote system
      ~R  - Request rekey (SSH protocol 2 only)
      ~#  - list forwarded connections
      ~?  - this message
      ~~  - send the escape character by typing it twice
    (Note that escapes are only recognized immediately after newline.)

You can close the list of Escape sequences by hitting &lt;kbd&gt;Enter ↵&lt;/kbd&gt;.

Notice that because hitting &lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt; causes `ssh` to send the `~` instead of intercepting it, you can address *N* nested `ssh` connections by hitting &lt;kbd&gt;~&lt;/kbd&gt; *N* times. (This only applies to &lt;kbd&gt;~&lt;/kbd&gt;s that directly follow an &lt;kbd&gt;Enter ↵&lt;/kbd&gt;.) That is to say that &lt;kbd&gt;Enter ↵&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;~&lt;/kbd&gt;&lt;kbd&gt;.&lt;/kbd&gt; terminates an `ssh` session 5 layers deep and keeps the other 4 intact.&quot;

I&#39;m wondering if its possible to programmatically discover all the endpoints of a particular API. 

So for example if I GET this URL with a browser or curl:
https://api.twitter.com/1.1/

I might get something like this as a JSON response:

```
&quot;TwitterAPI&quot;:{
	&quot;version&quot; : 1.1,
	&quot;GET&quot; : {
		&quot;search/&quot; : [&quot;users&quot;, &quot;trending&quot;],
		&quot;users/&quot; : [&quot;id&quot;, &quot;handle&quot;]
	}
}
```

Of course Twitter could choose to publish or not publish this format. So as a side question, are there any libraries for Java or JavaScript that will automatically map and publish the API routes you created in your controllers?  

Is there a way to discover all endpoints of a REST API?

Sometimes an SSH session to a remote server will freeze indefinitely due to bad internet connectivity. Is it possible to close the session without closing the terminal?

I have been developing an Ansible playbook for a couple of weeks, therefore, my experience with such technology is relatively short. Part of my strategy includes using a custom &lt;code&gt;ansible_ssh_user&lt;/code&gt; for provisioning hosts throughout the inventory, however, such user will need its own SSH key pair, which would involve some sort of a plan for holding/storing its correspondent private key. On a production environment, this playbook would be cloned/pulled and run inside a certain *playbook node* whose role is to provision the rest of the infrastructure.

At first, I was thinking to just put that private key inside the playbook git repository, but I am having second thoughts about it nonetheless, mostly because of somewhat obvious security reasons and common sense around it, hence the reason I need to consult you about this matter. 

With this set on the table, here are the follow-up questions:

* In an Ansible-based development environment, is it sane/reasonable to hold a private SSH key in source control?
* Would this practice be advised *only for development environments* whereas another local git branch inside the *playbook node* would be then used to hold the actual production SSH private key?
* Would it be better to address this case scenario via Ansible Vault instead?, I have not ever used this before, but regardless of that I cannot yet tell whether this would be a proper case for using it.
* In your experience, what would be your approach around this in a production environment?, what would it be considered as the best practice in this particular scenario?

Ansible SSH private key in source control?

I have a simple script:

    #!/bin/bash
    for server in $(~/.ansible/ansible_hosts)
    do
        ssh $server &quot;hostname; readlink /opt/mydir/mylink;&quot;
    done

It works fine - the program returns the correct hostname and link - except that I get the following error on some but not all of the servers:

**shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory**

All the directories exist. One of the most common suggestions has been to add a cd, a cd -, or a cd /. All that happens when that step is added is an additional:

**chdir: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory**

I tried kickstarting the nfs daemon on the off chance that there was some confusion about my homedir and substituted /etc/init.d in case the problem was with /opt. No difference

This would simply be an annoyance except that when I try to use an ansible playbook instead of a simple ssh command it fails for that server.

Any insights would appreciated.

I&#39;m trying to connect to vagrant via `homestead ssh`:

    vagrant@127.0.0.1&#39;s password:

But my public key password doesn&#39;t work.&lt;br&gt;
My Homestead.yaml looks like this:

    authorize: ~/.ssh/id_rsa.pub
    
    keys:
        - ~/.ssh/id_rsa

I&#39;m using &quot;Laravel Homestead version 2.0.14&quot; with &quot;Vagrant 1.7.2&quot;.

Is there a default password to connect to vagrant when using `homestead ssh` for the first time?

I have some aliases for ssh, example:

    alias buildWork=&quot;ssh work &#39;~/build_app&#39;&quot;

The problem is that the `ssh` command passes some variables like `$LC_CTYPE` that causes some errors.

How to prevent that and use the server configurations ?

How not to pass the locale through an ssh connection command

I&#39;m trying to pg_dump a SQL database on a remote server in our DMZ. There are 2 problems. 

1) there is not a lot of space left on the remote server so the normal command run to locally backup the database 
`pg_dump -C database &gt; sqldatabase.sql.bak`  won&#39;t work due to space issues. 


2) I also can&#39;t run the other version of pg_dump command to dump database from remote server to local server using: 

    pg_dump -C -h remotehost -U remoteuser db_name | psql localhost -U localuser db_name

as the server is in our DMZ and port 5432 is blocked. What I&#39;m looking to see is if it is possible to pg_dump the database and immediatly save it (ssh or some other form) as a file to a remote server. 
What I was trying was:   `pg_dump -C testdb | ssh admin@ourserver.com | &gt; /home/admin/testdb.sql.bak` 

Does anyone know if what i am trying to achieve is possible?
