DJP - free portable cross-platform desktop graphical multi pinger, 100%-pure java. Local and remote (to syslog-server) logging support. At first DJP use ICMP for ping, if it is unavailable, it tries to check hosts with TCP/echo. Use standart OS ICMP packet-size - Linux=64 bytes, Windows=32 bytes. In addition to local-log also present syslog-server support: then any host down, DJP write message to local log and can send message to syslog-server. TCP port scaner and Telnet connection to host support. Also support backup/restore DB+CFG files to/from zip-archive. Simple and intuitive GUI - Graphical User Interface. Successfully tested in Windows and Linux for more than 100 hosts. Example of using CDI (Weld) and JPA (EclipseLink / OpenJPA) in Java SE application. Support both IPv4 and IPv6. Need only JRE 1.8 - https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html . See also Jennom project - http://jennom.sourceforge.net
