a simple wrapper for ping
A simple network ping tool. Supports TCP / UDP / ICMP protocol.
Asynchronous implementation of ICMP ping using EventMachine. Can be used to ping many hosts at once in a non-blocking fashion, with callbacks for success, timeout, and host failure/recovery based on specified threshold numbers.
The net-ping library provides a ping interface for Ruby. It includes separate TCP, HTTP, LDAP, ICMP, UDP, WMI (for Windows) and external ping classes.
# Netchk Simple tool to troubleshoot internet connectivity issues. This tool verifies: - your computer has at least one IP address - you have at least one DNS configured - you can reach the configured nameservers - the nameservers can resolve hosts Finally, some ICMP ping statistics are presented with average durations and error rates. ## Installation ```sh gem install netchk ``` ## Usage Just run `netchk` from your terminal and basic diagnosis will start showing you progress and any error if present. Note: On Linux system, this gem requires `sudo` to perform the ICMP ping operations. On macOS, this is not needed. You also can configure how netchk verifies your connections by configuring a `~/.netchk.yaml` or `~/.netchk.yml` file like below. ```yaml # Settings to test DNS server connectivity. dns: # Path to resolv.conf file to check presence and connectivity of DNS. # Path should be absolute to avoid issues when running netchk # from different directories. resolv.conf: /etc/resolv.conf # Settings to test DNS resolution. resolv: # Path to resolv.conf file to use for testing DNS resolution. # Path should be absolute to avoid issues when running netchk # from different directories. It is advised to be the same # as dns.resolv.conf. resolv.conf: /etc/resolv.conf # The list of domains to test for DNS resolution. domains: - google.com - youtube.com - facebook.com # Settings to test icmp ping. icmp: # A list of hosts to ping with ICMP. It is advised to use # IP addresses instead of domains to rule out any issues with # DNS resolution, which is tested separately. hosts: - 1.1.1.1 - 8.8.8.8 # The number of ping to issue each host. count: 20 # The duration in seconds to wait between each ping. # Setting this value too low might cause timeouts. interval: 0.2 ``` Each value is optional. If one is missing the default value will be used. The file above shows the default values. ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/moray95/netchk.
# holepunch [](http://badge.fury.io/rb/holepunch) [](https://travis-ci.org/undeadlabs/holepunch) Holepunch manages AWS EC2 security groups in a declarative way through a DSL. ## Requirements - Ruby 1.9.3 or newer. ## Installation ```bash gem install holepunch ``` or in your Gemfile ```ruby gem 'holepunch' ``` ## Basic Configuration You need to provide your AWS security credentials and a region. These can be provided via the command-line options, or you can use the standard AWS environment variables: ```bash export AWS_ACCESS_KEY_ID='...' export AWS_SECRET_ACCESS_KEY='...' export AWS_REGION='us-west-2' ``` ## The SecurityGroups file Specify your security groups in a `SecurityGroups` file in your project's root. Declare security groups that you need and the ingresses you want to expose. You can add ingresses using `tcp`, `udp`, and `ping`. For each ingress you can list allowed hosts using group names or CIDR notation. ```ruby group 'web' do desc 'Web servers' tcp 80 end group 'db' do desc 'database servers' tcp 5432, 'web' end group 'log' do desc 'log server' tcp 9999, 'web', 'db', '10.1.0.0/16' end ``` An environment can be specified which is available through the `env` variable. This allows you to have custom security groups per server environment. ```ruby group "#{env}-web" group "#{env}-db" do tcp 5432, "#{env}-web" end ``` Your application may depend on security groups defined by other services. Ensure they exist using the `depends` method. ```ruby depends 'my-other-service' group 'my-service' do udp 9999, 'my-other-service' end ``` You may specify port ranges for `tcp` and `udp` using the range operator. ```ruby group 'my-service' do udp 5000..9999, '0.0.0.0/0' end ``` You can specify ping/icmp rules with `icmp` (alias: `ping`). ```ruby group 'my-service' do ping '10.0.0.0/16' end ``` It can be useful to describe groups of security groups you plan to launch instances with by using the `service` declaration. ```ruby service "#{env}-web" do groups %W( admin #{env}-log-producer #{env}-web ) end ``` ## Usage Simply navigate to the directory containing your `SecurityGroups` file and run `holepunch`. ``` $ holepunch ``` If you need to specify an environment: ``` $ holepunch -e live ``` You can get a list of security groups for a service using the `service` subcommand. ``` $ holepunch service -e prod prod-web admin,prod-log-producer,prod-web ``` You can also get a list of all defined services. ``` $ holepunch service --list ``` ## Testing You can run the unit tests by simply running rspec. ``` $ rspec ``` By default the integration tests with EC2 are not run. You may run them with: ``` $ rspec -t integration ``` ## Authors - Ben Scott (gamepoet@gmail.com) - Pat Wyatt (pat@codeofhonor.com) ## License Copyright 2014 Undead Labs, LLC.
