Moin,

ich versuche mit zunehmender Verzweiflung auf einem Opensuse12.1 fail2ban zu installieren. Installation hat funktioniert. Dienst wird auch gestartet. IPtables habe ich auf true gestellt in der jail.local.

Alles soweit so gut. aber das teil weigert sicht irgendwas zu bannen.

Hallo,

was sagt denn das Logfile (/var/log/fail2ban.log) - ggf. mit erhöhtem Loglevel (Option "loglevel" in der Konfigurationsdatei)? - Und wie sieht die Konfigurationsdatei überhaupt aus?

Gruß,
Gersen
Bitte warten ..

Hi,

IPtables auch konfiguriert?
Fail2Ban ist ohne eine "Basis-Konfiguration" recht machtlos.

Gruß
Bitte warten ..

Poste doch mal die Konfiguration (/etc/fail2ban/jail.conf, glaube ich). Du kannst den Inhalt ja auch mal mit diesem Beispiel abgleichen. Welche Dienste willst Du denn mit f2b absichern?

Hi,

eigentlich nur SSH. leider kann ich meinem Chef ein Pubkey-Verfahren nicht schmackhaft machen. Hab zwar den Standartport geändert, hat aber nich völlig geholfen...



  1. Fail2Ban configuration file
  1. Author: Cyril Jaquier
  1. $Revision: 611 $

  1. The DEFAULT allows a global definition of the options. They can be override
  2. in each jail afterwards.

[DEFAULT]

  1. "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not
  2. ban a host which matches an address in this list. Several addresses can be
  3. defined using space separator.
ignoreip = 127.0.0.1

  1. "bantime" is the number of seconds that a host is banned.
bantime = 3600

  1. A host is banned if it has generated "maxretry" during the last "findtime"
  2. seconds.
findtime = 600

  1. "maxretry" is the number of failures before a host get banned.
maxretry = 5

  1. "backend" specifies the backend used to get files modification. Available
  2. options are "gamin", "polling" and "auto". This option can be overridden in
  3. each jail too (use "gamin" for a jail and "polling" for another).
  1. gamin: requires Gamin (a file alteration monitor) to be installed. If Gamin
  2. is not installed, Fail2ban will use polling.
  3. polling: uses a polling algorithm which does not require external libraries.
  4. auto: will choose Gamin if available and polling otherwise.
backend = auto


  1. This jail corresponds to the standard configuration in Fail2ban 0.6.
  2. The mail-whois action send a notification e-mail with a whois request
  3. in the body.

[ssh-iptables]

enabled = true
filter = sshd
action = iptables[name=SSH, port=ssh, protocol=tcp]
sendmail-whois[name=SSH, dest=<meineAdresse>, sender=fail2ban@mail.com]
logpath = /var/log/messages
maxretry = 5

[proftpd-iptables]

enabled = false
filter = proftpd
action = iptables[name=ProFTPD, port=ftp, protocol=tcp]
sendmail-whois[name=ProFTPD, dest=you@mail.com]
logpath = /var/log/messages
maxretry = 6

  1. This jail forces the backend to "polling".

[sasl-iptables]

enabled = false
filter = sasl
backend = polling
action = iptables[name=sasl, port=smtp, protocol=tcp]
sendmail-whois[name=sasl, dest=you@mail.com]
logpath = /var/log/mail

  1. Here we use TCP-Wrappers instead of Netfilter/Iptables. "ignoreregex" is
  2. used to avoid banning the user "myuser".

[ssh-tcpwrapper]

enabled = false
filter = sshd
action = hostsdeny
sendmail-whois[name=SSH, dest=you@mail.com]
ignoreregex = for myuser from
logpath = /var/log/messages

  1. This jail demonstrates the use of wildcards in "logpath".
  2. Moreover, it is possible to give other files on a new line.

[apache-tcpwrapper]

enabled = false
filter = apache-auth
action = hostsdeny
logpath = /var/log/apache2/error_log
maxretry = 6

  1. The hosts.deny path can be defined with the "file" argument if it is
  2. not in /etc.

[postfix-tcpwrapper]

enabled = true
filter = postfix
action = hostsdeny
sendmail[name=Postfix, dest=you@mail.com]
logpath = /var/log/mail
bantime = 300

  1. Do not ban anybody. Just report information about the remote host.
  2. A notification is sent at most every 600 seconds (bantime).

[vsftpd-notification]

enabled = false
filter = vsftpd
action = sendmail-whois[name=VSFTPD, dest=you@mail.com]
logpath = /var/log/messages
maxretry = 5
bantime = 1800

  1. Same as above but with banning the IP address.

[vsftpd-iptables]

enabled = false
filter = vsftpd
action = iptables[name=VSFTPD, port=ftp, protocol=tcp]
sendmail-whois[name=VSFTPD, dest=you@mail.com]
logpath = /var/log/messages
maxretry = 5
bantime = 1800

  1. Ban hosts which agent identifies spammer robots crawling the web
  2. for email addresses. The mail outputs are buffered.

[apache-badbots]

enabled = false
filter = apache-badbots
action = iptables-multiport[name=BadBots, port="http,https"]
sendmail-buffered[name=BadBots, lines=5, dest=you@mail.com]
logpath = /var/log/apache2/access_log
bantime = 172800
maxretry = 1

[courierpop3]

enabled = false
port = pop3
filter = courierlogin
action = iptables[name=%(__name__)s, port=%(port)s]
logpath = /var/log/mail
maxretry = 5


[courierimap]

enabled = false
port = imap2
filter = courierlogin
action = iptables[name=%(__name__)s, port=%(port)s]
logpath = /var/log/mail
maxretry = 5

Nö, es gibt aber ein Code-Tag, mit dem man das etwas üebrsichtlicher darstellen lassen kann.
