What Is SSH and When Should I Use It?

Secure Shell (SSH), also sometimes called Secure Socket Shell, is a protocol for securely accessing your site's server over an unsecured network. In other words, it's a style to safely log in to your server remotely using your preferred command-line interface:

Unlike File Transfer Protocol (FTP), which only enables you to upload, delete, and edit files on your server, SSH can attain a broad range of tasks. For instance, if an mistake locks you out of your WordPress site, yous can use SSH to access it remotely.

This protocol also enables you to use several primal developer tools, including:

• WP-CLI. The WordPress command line. You tin use information technology for a variety of tasks, including new installations, bulk plugin updates, and media file imports.
• Composer. A PHP package director. It enables you to implement several frameworks for use in your site'southward code by pulling the necessary libraries and dependencies.
• Git. A version control system used to track changes in lawmaking. This is especially useful for teams of developers working together on a single project.
• npm. A JavaScript parcel managing director. It includes a command-line and JavaScript software registry. Note: Kinsta customers will need an Enterprise plan in club to access this feature.

It's important to note that using SSH is an advanced skill. Generally speaking, lay users of WordPress should contact their developers or hosting providers for help, rather than trying to resolve issues with SSH themselves.

Why Is My SSH Connection Refused? (5 Reasons for Connectivity Errors)

Unfortunately, in that location are many scenarios that could occur while you're trying to connect to your server via SSH, which might result in an fault reading "Connection refused".

Below are some of the about common issues that might exist causing problems for you lot.

1. Your SSH Service Is Downwards

In order to connect to your server with SSH, it must be running an SSH daemon – a program that runs in the background to listen for and take connections.

If this service is downward, you will not be able to successfully connect to your server and may receive a Connection refused error:

Your server's SSH daemon may exist down for a broad variety of reasons, including unexpected traffic spikes, resource outages, or even a Distributed Denial of Service (DDoS) set on. In add-on to the troubleshooting steps we'll mention below, you may want to contact your hosting provider to determine the root crusade of the event.

If yous suspect that your SSH service might be down, you tin can run this command to discover out:

          sudo service ssh status        

If the control line returns a status of down, then you've likely found the reason behind your connectivity fault.

two. Y'all Have the Wrong Credentials

Although it may seem likewise simple to be true, it's possible that you're just entering the incorrect credentials when trying to connect to your server. In that location are four pieces of data needed to run SSH:

• Host name. The IP address of the server you're trying to connect to or your domain proper noun.
• Username. Your (Due south)FTP username.
• Password. Your (S)FTP countersign.
• Port. The default port is 22. However, some hosting providers (including Kinsta) change their SSH port number for security reasons. If this is the example, you should be able to find it by logging in to your MyKinsta dashboard.

You can besides check to run into which port is being used for SSH by running this command:

          grep Port /etc/ssh/sshd_config        

The command line should render the correct port.

iii. The Port Y'all're Trying to Use Is Closed

A "port" is merely the endpoint to which you lot're directed when connecting to your server. In improver to making certain you accept the correct one, you'll as well want to check to see if the port you're trying to apply is open.

Any open up port is a security vulnerability, as hackers tin can try to exploit it and proceeds access to the server. For this reason, unused ports are often airtight to forestall attacks.

In the effect that port 22, or the custom SSH port for your server, has been closed, you will probable see a Connectedness refused error. You tin can run across all the ports listening on your server by running this control:

          sudo lsof -i -north -P | grep Mind        

This control should render a list of ports with the Heed state. Ideally, yous want to see port 22 or your server's custom SSH port listed here. If it's not, y'all'll need to reopen the port in order to connect to your server.

iv. SSH Isn't Installed on Your Server

As we briefly mentioned earlier, servers apply SSH daemons to listen for and accept connections. Therefore, if the server you're trying to connect to doesn't have ane installed, you won't be able to access it using SSH.

Generally speaking, almost all hosting providers will have SSH daemons installed on their servers by default. This particular upshot is more common on localhost or defended servers.

5. Firewall Settings Are Preventing an SSH Connexion

Since open ports present a security risk, firewalls installed to protect servers from hackers sometimes block connections to them. Unfortunately, this ways that even harmless users who are trying to SSH into their servers may receive a Connectedness refused error equally a result of firewall settings.

If your setup appears to be in social club and you still can't connect, have a await at your firewall'south rules. Yous can brandish them in your command-line interface with the following commands:

          sudo iptables-save # display IPv4 rules        

          sudo ip6tables-relieve # brandish IPv6 rules        

Your results will vary, but you lot'll want to wait for these elements to determine if your firewall is blocking SSH connections:

• dport 22: This refers to the destination port, which for SSH is usually port 22 (reminder: Kinsta doesn't use this port number).
• Decline: This would indicate that connections are being refused from the specified destination.
• DROP: Like REJECT, this ways that connections to the relevant port are being blocked.

If you search the results of the commands above for dport 22, you should be able to determine if your firewall is preventing an SSH connection. If so, yous'll have to change the rules to accept requests.

Why Does PuTTY Say Connexion Refused?

PuTTY is an SSH customer. If you're familiar with FTP, this platform is the FileZilla equivalent to SSH on Windows machines. In other words, PuTTY enables users to input their credentials and launch an SSH connection:

The PuTTY website

If you're a PuTTY user and run across the Connection refused error, the cause is probable i of those listed above.

This is an SSH connectivity error like whatever other, and the troubleshooting tips below should work whether you're using PuTTY, Terminal, or whatever other program for connecting to your server with SSH.

How Practice I Troubleshoot SSH Connectivity Errors?

When y'all're experiencing an SSH connectivity error, at that place are a few steps you lot can take to troubleshoot it depending on the cause. Hither are some tips for troubleshooting the reasons for a Connexion refused error that we covered higher up:

• If your SSH service is down. Contact your hosting provider to see why your SSH service isn't running. For localhost or defended servers, you can use the command sudo service ssh restart to endeavour to get information technology running again.
• If you entered the wrong credentials. Once yous've double-checked the SSH port using the grep Port /etc/ssh/sshd_config command, try connecting over again with the correct details.
• If your SSH port is closed. This is usually a side issue of one of the two reasons listed beneath. Either install an SSH daemon on the server you desire to connect to or change your firewall rules to accept connections to your SSH port.
• If SSH isn't installed on your server. Install an SSH tool such as OpenSSH on the server you want to connect to using the sudo apt install openssh-server control.
• If your firewall is blocking your SSH connexion. Disable the firewall rules blocking your SSH connection by irresolute the destination port's settings to ACCEPT.

If you're attempting to connect to your hosting provider'due south server, it may be wiser to contact back up than to try troubleshooting the trouble yourself. Users on localhost or defended servers may be able to find further support on more than avant-garde forums if none of the higher up solutions works.
