Large Number of Failed Login Attempts from IP 66.111.33.91

Mai cu spor, zic … Si cu mai multa imaginatie.

5 failed login attempts to account stealthsettings (system) — Large number of attempts from this IP: 66.111.33.91

5 failed login attempts to account ymvista (system) — Large number of attempts from this IP: 66.111.33.91

Ma tot f*#e unu` de pe diverse IP-uri, de aproximativ 2-3 saptamani. Tot incearca sa sparga serverul, folosind userele site-urilor hostate. Cel putin asa crede el, ca numele site-urilor, trebuie sa aibe si un user pe server (id=0, eventual),  si daca se poate cu o parola gen data nasterii.

Ei bine, dragul meu, afla ca la 5 incercari esuate pe sshd (asta daca stii user-ul, si daca este acceptata logarea necriptata via SSH Key si fara ip-uri filtrate), serverul executa ban / silence pe IP, pentru cateva minute. Suficient de mult, cat sa-ti blocheze performantul generator de parole.

Doua ponturi pentru tine:

1. Nici un site (cont), nu are user cu access ssh.

2. Daca ai norocul (unu la cateva miliarde) sa treci de APF (Advanced Policy Firewall) si de ochiul meu, te asigur ca o sa tragi o gura zdravana de (BFD) Brute Force Detection.

root@server [~]# iptables -I INPUT -s 66.111.33.91 -j DROP
root@server [~]# service iptables save
Saving firewall rules to /etc/sysconfig/iptables:          [  OK  ]
root@server [~]#

Succes!
