Environment: Fedora 33, fail2ban-0.11.2-1.fc33.noarch
I have had to work around the following error found in the fail2ban.log:
Jail 'sendmail-auth' started
2021-01-18 08:36:47,945 fail2ban.filter [38540]: WARNING
[sendmail-auth] Simulate NOW in operation since found time has too large
deviation 1610976475.254356 ~ 1610>
2021-01-18 08:36:47,945 fail2ban.filter [38540]: WARNING
[sendmail-auth] Please check jail has possibly a timezone issue. Line
with odd timestamp: ....
This has occurred on a few of the jails but let's focus on one -
sendmail-auth in jails.local
[sendmail-auth]
enabled = true
port = submission,465,smtp,59025
logpath = %(syslog_mail)s
#backend = %(syslog_backend)s
To make this jail successfully start I had to comment out the following
backend and in paths-fedora.conf comment out the following:
#syslog_backend = systemd
#sshd_backend = systemd
dropbear_backend = systemd
proftpd_backend = systemd
pureftpd_backend = systemd
wuftpd_backend = systemd
postfix_backend = systemd
#dovecot_backend = systemd
I do realize for the purposes of this example dovecot and sshd are not
relevant to the sendmail-auth issue
Additionally, I have in jail.conf:
[INCLUDES]
#before = paths-distro.conf
before = paths-fedora.conf
and
backend = auto
The bottom line is that I am unsure why I had to employ this
workaround. Anyone have a clue why I had to essentially eliminate backend?
