Много ботово се опитват да се логнат с brutforce и ето едно просто решение (не е 100% гаранция, но е втора бариера един вид…)

Разпознаване на глас, чрез гугъл: https://github.com/amsehili/gspeech-rec

Клиента се свързва с машината която има реално IP(DOMAIN.bg) и прави отворен порт 19999

ssh -R 19999:127.0.0.1:22 [email protected] -oPort=33

Когато на DOMAIN.bg се вържем през ssh на 19999 ще се свържем директно със ssh-а на машината с нереално IP

Пример
На машината с реално ИП (DOMAIN.bg):
ssh [email protected] -p 19999

Свързваме се директно към машината с нерелно IP

Проблема беше, че има фтп потребител на машината който влиза, но се знае паролата и за да не се променя затова се реши да се пусне tcpdump и така да се прослуша с каква парола влиза потребител в съответната машина:

tcpdump -l -A src IP_CLIENT and port ftp

tcpdump port http or port ftp or port smtp or port imap or port pop3 -l -A | egrep -i 'pass=|pwd=|log=|login=|user=|username=|pw=|passw=|passwd=|password=|pass:|user:|username:|password:|login:|pass |user ' --color=auto --line-buffered -B20
