Hi,
I recently installed Fail2Ban 0.9.3 on a Ubuntu 16.04 System,
and am trying to create custom action shortcuts to reuse
in my custom jail files.
The jails themselves work fine, the custom DEFAULTS-file
is being loaded, but when trying to start Fail2Ban, Jails
using my custom action shortcut are not beig started.
My common data file (jails.d/jails.common) contains the following entries:
----
[DEFAULT]
destemail = d...@server.com
sender = sen...@server.com
sendername = Some Fail2Ban Sender
action_c = %(banaction)s[name=%(__name__)s, bantime="%(bantime)s",
port="%(port)s", protocol=tcp, chain=mychain]
action_cd = %(banaction)s[name=%(__name__)s, bantime="%(bantime)s",
port="%(port)s", protocol=tcp, chain=mychain]
%(mta)s-custom[name=%(__name__)s, dest="%(destemail)s",
sender="%(sender)s", chain=mychain]
----
and my CustomJail.conf contains this
----
[INCLUDES]
before = jails.common
[customjail]
port = http,https
action = %(action_cd)s
logpath = /path/to/logfile
enabled = true
maxretry = 1
bantime = 1
----
the low values for maxretry and bantime obviously for testing purposes.
However, starting Fail2Ban with this configuration fails wih this error
message:
ERROR Failed during configuration: Bad value substitution: option
'action' in section 'customjail' contains an interpolation key
'action_cd' which is not a valid option name. Raw value: '%(action_cd)s'
For architectural reasons, I do not want to rewrite jail.local for this,
as these actions should not be available for all jails.
I am quite lost and qould appreciate help, as I did not find any hint on
this either in the mailing lists or google or anywhere, really.
Kind regards, Stefan
