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

Грешка:
"PHP Fatal error: Redefinition of parameter $id_shop in /var/www/modules/spverticalmenu/Verticalmenu.php on line 655"

Решение:
Стар код:
protected function getCMSPages($id_cms_category, $id_shop = false, $id_lang = false, $id_shop = false)
{
$id_shop = ($id_shop !== false) ? (int)$id_shop : (int)Context::getContext()->shop->id;
$id_lang = $id_lang ? (int)$id_lang : (int)Context::getContext()->language->id;
Нов код:
public function getCMSPages($id_cms_category, $id_shop = false, $id_lang = false, $id_shop2 = false, $is_list = false)
{
$id_shop = ($id_shop !== false) ? (int)$id_shop : (int)Context::getContext()->shop->id;
