How To Connect To A Specific Network

Overview

This guide provides instructions on how to connect to specifc EOSIO blockchain when using cleos. Cleos can connect to a specific node by using the --url optional argument, followed by the http address and port number.

The examples use the --urloptional argument to send commands to the specified blockchain.

[[info | Default address:port]] | If no optional arguments are used (i.e. no --url), cleos attempts to connect to a local nodeos running at localhost or 127.0.0.1 and default port 8888. Use the nodeos command line arguments or config.ini file to specify a different address.

Before you Begin

Make sure you meet the following requirements:

• Install the currently supported version of cleos. [[info | Note]] | Cleos is bundled with the EOSIO software. Installing EOSIO will install the cleos and keosd command line tools.
• You have access to an EOSIO blockchain and the http afddress and port number of a nodeos instance.

Reference

See the following reference guides for command line usage and related options:

• cleos command

Example

1. Add the -url option to specify the nodeos instance

cleos -url http://nodeos-host:8888 COMMAND

Where

• -url http://nodeos-host:8888 = The http address and port number of the nodeos instance to connect to
• COMMAND = The cleoscommand.

Summary

In conclusion, by following these instructions you are able to connect to a specified nodeos instance.
