Имеется старый сервер. И конечно же уже никто не помнит, что за приложение на нём запущено. Приложение слушает порт 9090.
# ss -lntp
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
LISTEN 0 100 *:9090 *:* users:(("java",pid=115854,fd=31))
Как определить запущен ли процесс на какой либо платформе? Более менее информации получил с помощью ps:
# ps aux|grep java
