deadman

=======

deadman is an observation software for host status using ping.

deadman does not have rich functionalities. It only checks host

statuses using ICMP echo. We recomend using deadman for building

temporary networks such as conference and event networks. This

software was originally designed and implemented for Interop Tokyo

ShowNet.

How to use

==========

Clone this repository and then run.

	$ git clone https://github.com/upa/deadman

	$ cd deadman

	$ ./deadman deadman.conf

To change the targets, modify or create a config file.

	$ cat deadman.conf

	google          173.194.117.176

	googleDNS       8.8.8.8

	---

	kame            203.178.141.194

	kame6           2001:200:dff:fff1:216:3eff:feb1:44d7

`deadman` with `-a` or `--async-mode` option sends ping to targets

asynchronously.

Each line in the config file indicates a target host. Ping options,

specifying source addresses and using netns, etc, are noted on the

deadman.conf. For example, ping via a remote host through ssh is

implemented.

	google-via-ssh  173.194.117.176 relay=X.X.X.X os=Linux

This line means sending ping to a google server via the remote server

X.X.X.X. username and ssh-key for the remote host can be specified by

_user=USER_, _key=KEYPATH_. Other ssh attributes follow user's

environment executing deadman.

You can also use `---` to display the separator.

It's useful for grouping the targets.

Moreover, -s option indicates the scale of RTT bar graph. default is 10ms.

You can send deadman a SIGHUP to have it reload its configuration file.

When this happens, existing entries will not lose their history.
