deadman

deadman is, an observation software for host status using ping.

deadman does not have rich functionalities. It only checks the host status 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.

demo

how to use

At first, write a config file like below.

% 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

A line on the config file indicates an observed host. IPv6 address is naturally supported.

then,

% ./deadman deadman.conf

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

ping via remote host through ssh is implemented. For example,

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

this line means sending ping to a google server via remote server X.X.X.X. username and ssh-key for remote host can be specified by user=USER, key=KEYPATH. Other ssh attributes follow user's environment executing deadman.

You can send deadman a SIGHUP to have it reload its configuration file. When this happens, existing entries will not lose their history.
