PatD: MasarLabs Ping and Traceroute Daemon
For a project I'm working on I have to ping many hosts from a Java program: I could to run Java as root or I could fork external executables like fping (http://fping.org), but I don't like these options, so I wrote patd (/patd).
Features
- Does ping and traceroute.
- Supports both IPv4 and IPv6.
- Single daemon listening on a TCP local port.
- Single threaded.
- Does not run as root but uses capabilities to send ICMP packets.
There is also a client pat (/patd/pat.html) to send commands to patd (/patd).
Downloads
You can download the sources of patd from here (/download).
There are also binary compiled for Debian Linux (http://www.debian.org) in our APT Repository (/debian)
Examples
Here are two examples of pat/patd.
Ping an host
- $> pat www.example.com
- pat6 2606:2800:0220:006D:2626:1447:1097:0AA7
- O 2606:2800:0220:006D:26BF:1447:1097:0AA7 seq=1 time=88.374781 ms
- pat4 93.184.216.119
- O 93.184.216.119 seq=1 time=129.832764 ms
Tracerout an Host
- $> pat -T www.example.com
- pat6 2606:2800:0220:006D:2626:1447:1097:0AA7
