Hallo,
wie kann ich an meinem vServer einstellen, dass nach 3 fehlerhaften Loginversuchen die IP des Angreifers gesperrt wird oder sonst irgendein Schutzmechanismus?
Meine Passwörter sind zwar recht sicher und die Person wird noch ein paar Jahre brauchen um es zu knacken:rolleyes: aber lästig sind diese Versuche schon.

Kann ich diese Person anzeigen bringt das was? Die IP-Adresse kommt atm aus Indien war aber auch schon Finnland und Holland :D Welche Möglichkeiten hab ich um dem Typen die Hammelbeine lang zu ziehen?

Hier mal ein kleiner Auszug
variante 1 -verschiedene User

fail2ban ist ganz gut - setzt allerdings iptable Handlung voraus, was auf nem vServer ja nicht so selbstverständlich ist.

Du kannst dir die Mühe machen und die entsprechenden Anbieter zu denen die IPs gehören abusen - mittels Whois findest du die zugehörigen Emailadressen der Abuseabteilungen. Bringt dir aber persönlich auch nichts. Ist halt einfach so. Als recht einfache Lösung kann man z.B. den SSH-Port verlegen, damit hält man sich schon mal das meiste vom Leib.
 
danke fail2ban scheint ja schonmal das richtige zu sein :) mit den iptable Handlungen hab ich nicht so ganz verstanden, dass soll ja auch fail2ban machen =)

das mit dem ssh port verlegen frag ich mich ob das sinvoll ist, es wird ja eh durchprobiert

Das kostet ja nur Zeit wenn ich da hinterher bin und die abuse abteilungen anschreibe.
 
Ich habe auch gute Erfahrungen mit "denyhosts" gemacht.
Aber im Endeffekt ist es ja doch nur Kosmetik für die Logfiles.

nö, was Du da siehst ist der abgehende Port des ssh-Clients, der natürlich jedesmal anders ist. Wenn Du den Port von Deinem sshd auf irgendwas > 1024 legst, sollte weitestgehend Ruhe herrschen (den musst Du Dir dann natürlich gut merken:) ), ganz ohne dynamisch angepasste iptables.

LinuxAdmin
 
Irgendwie habe ich Probleme meinen Port zu verlegen.
Habe in /etc/ssh
vi sshd_config ausgeführt den port umgestellt und gespeichert. Erneutes öffnen bestätigt mir auch die Änderung.
Wenn ich jetz in /etc/init.d
ssh reload oder ssh restart eingebe kommt folgene Meldung
Code: 
ssh: connect to host reload port 22: No route to host
ssh: connect to host restart port 22: No route to host
achja /etc/init.d sshd restart geht irgendwie nicht
bei sshd kommt sshd re-exec requires execution with an absolute path

Du sollst auch
Code: 
/etc/init.d/ssh
restart eingeben und nicht einfach
Code:

Dies hat nämlich zur Folge, dass Du auf dem Server einen Client startest, der zum Host "reload", respektive "restart" connecten soll, was natürlich nicht klappt.
 
Also hab jetzt /etc/init.d/sshd restart eingegeben.
/etc/init.d/ssh restart geht nicht

Hat vielleicht noch jemand ein Tip warum port 22 noch aktiv ist? unter 1137 wird die connection refused :mad:

Glaub ich nicht :p Wenn wirklich Port 1137 dort drin stehen würde, würde der sshd sich nach dem restart nicht mehr auf Port 22 melden, sondern auf 1137. Leider fehlt bei dem von Dir angegebenen config-file die obere Hälfte...

Vielleicht nimmt der sshd ja auch ein ganz anderes config-file (was ich bei einer Standardinstallation aber sehr stark bezweifele...). Was bringt denn folgender Test (als root):
Code: 
/usr/sbin/sshd -eddd
Falls der Test nicht mit einem Fehler abbricht, solltest Du Dich tatsächlich einmalig auf Port 1137 einloggen können.

Wenn du die Config genau so live hast wundert mich das auch nicht :)

Eine Zeile mit # ist ein Kommentar, d.h. quasi keine deiner Anweisungen wird auch wirklich ausgeführt. Lösch mal das # vor dem "Port ..." und starte SSH neu (aber denk an FW vorher ;-)).

also mit root kann man sich dann nicht mehr einloggen aber ich kann mich dann mit userxy anmelden und dann per su root werden oder wie kann ich das verstehen?
