[SOLVED] Fail2Ban

Mam problem z konfiguracją fail2ban np. nie jestem banowany na 60s przy trzy krotnym błędnym wpisaniu hasło do ssh albo ftp.

Kod:

# Fail2Ban configuration file.
#
# This file was composed for Debian systems from the original one
# provided now under /usr/share/doc/fail2ban/examples/jail.conf
# for additional examples.
#
# Comments: use '#' for comment lines and ';' for inline comments
#
# To avoid merges during upgrades DO NOT MODIFY THIS FILE
# and rather provide your changes in /etc/fail2ban/jail.local
#


# The DEFAULT allows a global definition of the options. They ca$
# in each jail afterwards.


[DEFAULT]


# "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fa$
# ban a host which matches an address in this list. Several addr$
# defined using space separator.
ignoreip = 0.0.0.0


# External command that will take an tagged arguments to ignore,$
# and return true if the IP is to be ignored. False otherwise.
#
# ignorecommand = /path/to/command <ip>
ignorecommand =


# "bantime" is the number of seconds that a host is banned.
bantime  = 60


# A host is banned if it has generated "maxretry" during the las$
# seconds.
findtime = 60
maxretry = 3


# "backend" specifies the backend used to get files modification.
# Available options are "pyinotify", "gamin", "polling" and "aut$
# This option can be overridden in each jail as well.
#
# pyinotify: requires pyinotify (a file alteration monitor) to be installed.
#            If pyinotify is not installed, Fail2ban will use auto.
# gamin:     requires Gamin (a file alteration monitor) to be installed.
#            If Gamin is not installed, Fail2ban will use auto.
# polling:   uses a polling algorithm which does not require external libraries.
# auto:      will try to use the following backends, in order:
#            pyinotify, gamin, polling.
backend = auto


# "usedns" specifies if jails should trust hostnames in logs,
#   warn when reverse DNS lookups are performed, or ignore all hostnames in logs
#
# yes:   if a hostname is encountered, a reverse DNS lookup will be performed.
# warn:  if a hostname is encountered, a reverse DNS lookup will be performed,
#        but it will be logged as a warning.
# no:    if a hostname is encountered, will not be used for banning,
#        but it will be logged as info.
usedns = warn


#
# Destination email address used solely for the interpolations in
# jail.{conf,local} configuration files.
destemail = root@localhost
#
# ACTIONS
#


# Default banning action (e.g. iptables, iptables-new,
# iptables-multiport, shorewall, etc) It is used to define
# action_* variables. Can be overridden globally or per
# section within jail.local file
banaction = iptables-multiport


# email action. Since 0.8.1 upstream fail2ban uses sendmail
# MTA for the mailing. Change mta configuration parameter to mail
# if you want to revert to conventional 'mail'.
mta = sendmail


# Default protocol
protocol = tcp


# Specify chain where jumps would need to be added in iptables-* actions
chain = INPUT


#
# Action shortcuts. To be used to define action parameter


# The simplest action to take: ban only
action_ = %(banaction)s[name=%(__name__)s, port="%(port)s", protocol="%(protocol)s", chain="%(chain$


# ban & send an e-mail with whois report to the destemail.
action_mw = %(banaction)s[name=%(__name__)s, port="%(port)s", protocol="%(protocol)s", chain="%(cha$

Re: [SOLVED] Fail2Ban

Masz domyślny port ssh 22? Czy jakiś inny?

jak inny to zmień:
port     = ssh
na
port     = *PORT*

Re: [SOLVED] Fail2Ban

Jeśli masz inny port niż domyślny to w każdym przypadku.

Masz jakiegoś zabytkowego Linuxa 2.2 z Ipchains, że Tobie jest failban potrzebny?

Bo jeśli aktualny, to olej Fail2bana, i zainteresuj się celami hashlimit i recent i set  w Iptables i Ipsecie.
Przykłady:

https://forums.gentoo.org/viewtopic-p-7081326.html#7081326
https://forum.dug.net.pl/viewtopic.php?pid=269383#p269383

Dużo skuteczniejsze to i bardziej niezawodne, niż Fail2ban.


Do tego w Proftpd masz mod-ban:
http://www.proftpd.org/docs/contrib/mod_ban.html
a w SSH masz opcję [b]MaxAuthTries[/b], czy [b]PermitRootLogin  without-password[/b].
Tylko zanim coś zmienisz na serwerze, dokładnie przetestuj sobie w domu ustawienia, żeby jakiegoś przypału nie było.

Tu masz przykłady limitowania dostępu do portu SSH przez iptables.
http://www.nfire.eu/?m=articles&ms=print&article_id=34

Jak majstrujesz przy SSH, to wystaw sobie na innym porcie [b]Dropbear[/b]a albo [b]Webmin[/b]a, żebyś w razie czego nie został na lodzie.

Pozdro

Re: [SOLVED] Fail2Ban

Nie mam zabytkowego linuksa tylko zwykłego stable 8.2. Webmin

Aktualnie zarzucono jego rozwijanie w niektórych dystrybucjach np. opartych na Debianie z braku chętnych do opieki, utrudniając aktualizację serwerów z Sarge do Etch z braku alternatywnego programu.

Na oficjalnych repozytoriach dostępna jest wersja 1.180 z dystrybucji Sarge (poprzedniej stabilnej). Można jej używać z nowszymi wersjami Debiana z pewnymi ograniczeniami albo pobrać najnowszy pakiet ze strony projektu[/quote]
