How do I perform a traceroute/ping to an LWS service?

What is a traceroute?

A traceroute lets you know exactlyhow a data transmission has travelled from your computer to a server. A traceroute draws up a list of the computers and servers on the network involved in a specific Internet activity.

The traceroute will identify each computer and server as well as the time taken for data to pass from one computer to another. Traceroute can be very useful if someone is having difficulty accessing a website. It can help locate the problem.

How do I perform a traceroute from Windows?

The TRACERT command available in Windows lets you determine the route taken from your computer to the source server.

1. Open the"Command Prompt" application on your computer.

2. Type the following command in the command prompt:

traceroute -T -p 443 domain.com 

Replace "domain.com" with your domain name or the ip relating to the server.

The ip 127.0.0.1 must be replaced by the ip of the Web server and or the URL of your Web site without HTTPS.

The TRACERT command has several options that you can use. These options are as follows:

• -d : Prevents the conversion of IP addresses to Reverse DNS. This makes the traceroute display faster.
• -h: Defines the maximum number of hops in a traceroute. By default, the maximum value is 30. However, you can change the number of hops using the [-h Hop] option.
• -w: Timeout: this option specifies the time in milliseconds to wait for a response to a request. By default, this value is set to 4 seconds or 4000 milliseconds.
• -?: provides an overview of all possible TRACERT commands.

The command syntax is always as follows:

tracert [-d] [-h jump] [-w timeout] [source]

This gives:

tracert -d -h 50 -w 10000 127.0.0.1

The ip 127.0.0.1 must be replaced by the source ip or hostname you wish to reach.

How do I perform a traceroute under Linux?

Under Linux, the TRACEROUTE command allows you to search for the route taken between the machine on which the command is run and the target server.

The command looks like this:

traceroute [-w wait] [-m max_ttl] [-p port] [-q nrequetes] [-t tos] IP 

Like the TRACERT command available under Windows, the TRACEROUTE command has several options that you can add when executing the command. These options are as follows:

• [-m max_ttl]: Used to initialise the maximum value of the time_to_live parameter (maximum number of jumps).
• [-n]: Displays the IP address rather than DNS Reverses.
• [-p port]: Allows you to change the UDP listening port. The default port is 33434.
• [-t tos]: This is used to check whether the path is different depending on the type of service. The value of this option must be between 0 and 255.

Traceroute allows you to trace a specific port using the following command:

nmap -p  --traceroute 

How do I perform a traceroute on a Mac?

If you are using Mac OS, simply use the included network utility to determine the route.

1. Start the network utility and click on"Traceroute".

2. Enter the domain name for which you wish to perform a traceroute, for example cpanel5.lwshosting.com

3. Then click on the "Trace" button.

Conclusion

You can now perform a traceroute/ping on one of the services using LWS.
Traceroute and ping can be useful if you have problems accessing your website and/or connecting to your cPanel package.
