Здравствуйте. Есть ось debian 10, на ней установлена Vesta панель.
А также дополнительно fail2ban
Постоянно вижу как в Iptables, добавляются огромные списки блокировок, боты брутят 22 порт.
Смена порта в данной ситуации не интересует, вопрос как задать в конфигурационном файле блокировку сразу в ipset?
Чтобы не забивать iptables
Текущий конфиг:
[ssh-iptables]
enabled = true
filter = sshd
action = vesta[name=SSH]
logpath = /var/log/auth.log
maxretry = 3
sshd.conf
# Fail2Ban filter for openssh
#
# If you want to protect OpenSSH from being bruteforced by password
# authentication then get public key authentication working before disabling
# PasswordAuthentication in sshd_config.
#
#
# "Connection from <HOST> port \d+" requires LogLevel VERBOSE in sshd_config
#
[INCLUDES]
# Read common prefixes. If any customizations available -- read them from
# common.local
before = common.conf
[DEFAULT]
_daemon = sshd
# optional prefix (logged from several ssh versions) like "error: ", "error: PAM: " or "fatal: "
__pref = (?:(?:error|fatal): (?:PAM: )?)?
# optional suffix (logged from several ssh versions) like " [preauth]"
__suff = (?: \[preauth\])?\s*
__on_port_opt = (?: port \d+)?(?: on \S+(?: port \d+)?)?
# for all possible (also future) forms of "no matching (cipher|mac|MAC|compression method|key exchange method|host key type) found",
# see ssherr.c for all possible SSH_ERR_..._ALG_MATCH errors.
__alg_match = (?:(?:\w+ (?!found\b)){0,2}\w+)

# DEV Notes:
#
# "Failed \S+ for .*? from <HOST>..." failregex uses non-greedy catch-all because
# it is coming before use of <HOST> which is not hard-anchored at the end as well,
# and later catch-all's could contain user-provided input, which need to be greedily
# matched away first.
