Hi, I previously used (4.5.x, 4.6.0) the following Portknocking
configuration (from here http://shorewall.net/Events.html):
/etc/shorewall/actions:
#ACTION OPTION DESCRIPTION
SSHKnock #SSH Port Knocking
/etc/shorewall/action.SSHKnock:
#
# Shorewall version 4 - SSH_BLACKLIST Action
#
?format 2
###############################################################################
#ACTION SOURCE DEST PROTO DEST
# PORT(S)
IfEvent(SSH,ACCEPT:info,60,1,src,reset)\
- - tcp 22
SetEvent(SSH,ACCEPT) - - tcp 1600
ResetEvent(SSH,DROP:info)
/etc/shorewall/rules
#
# Knocking on the ssh port
#
DNAT- net loc:192.168.128.2 tcp 22
SSHKnock:info net $FW tcp
1599,1600,1601
SSHKnock net loc:192.168.128.2 tcp 22
After updating to 4.6.1.1, I had the following warnings:
Jun 20 18:27:34 WARNING: The destination zone (loc) is ignored in DNAT
rules /etc/shorewall/rules (line 30)
I had to change the DNAT- line and remove the loc:
You might wan to change your example at
http://shorewall.net/PortKnocking.html and remove the loc: in the DNAT-
line.
I also received the following error:
Jun 20 18:27:35 ERROR: -j is only allowed when the ACTION is INLINE with
no parameter /usr/share/shorewall/action.IfEvent (line 139)
from /etc/shorewall/action.SSHKnock (line 8)
from /etc/shorewall/rules (line 31)
I switched to the deprecated manual chain example http://shorewall.neill
t/PortKnocking.html to get my PortKnocking working again.
I would still prefer to use the Events system, how can I use get around
this error?
Best Regards
Torni
