Thanks to Yaroslav Halchenko. - Added new time format. No idea from where it comes... - Added new regex. Thanks to Tobias Offermann. - Try to match the regex even if the line does not contain a valid date/time. Described in Debian #491253. Thanks to Yaroslav Halchenko. - Removed "timeregex" and "timepattern" stuff that is not needed anymore. - Added date template for Day-Month-Year Hour:Minute:Second. - Added date pattern for Hour:Minute:Second. Thanks to Andreas Itzchak Rehberg. - Use current day and month instead of Jan 1st if both are not available in the log. Thanks to Andreas Itzchak Rehberg. - Improved pattern. Thanks to Yaroslav Halchenko. - Merged patches from Debian package. Thanks to Yaroslav Halchenko. - Changed to SVN version. Conflicts: MANIFESTdebian-upstream

# Submits attack reports to DShield (http://www.dshield.org/)
|

|

# You MUST configure at least:
|
||||
# <port> (the port that's being attacked - use number not name).
|
||||
#
|
||||
# You SHOULD also provide:
|
||||
# <myip> (your public IP address, if it's not the address of eth0)
|
||||
# <userid> (your DShield userID, if you have one - recommended, but reports will
|
||||
# be used anonymously if not)
|
||||
# <protocol> (the protocol in use - defaults to tcp)
|
||||
#
|
||||
# Best practice is to provide <port> and <protocol> in jail.conf like this:
|
||||
# action = dshield[port=1234,protocol=tcp]
|
||||
#
|
||||
# ...and create "dshield.local" with contents something like this:
|
||||
# [Init]
|
||||
# myip = 10.0.0.1
|
||||
# userid = 12345
|
||||
#
|
||||
# Other useful configuration values are <mailargs> (you can use for specifying
|
||||
# a different sender address for the report e-mails, which should match what is
|
||||
# configured at DShield), and <lines>/<minreportinterval>/<maxbufferage> (to

|

# <protocol> (the protocol in use - defaults to tcp)
|

# action = mynetwatchman[port=1234,protocol=udp]
|

#
|

# ...and create "mynetwatchman.local" with contents something like this:

# [Init]
|

# mnwlogin = me@example.com
|
||||
# mnwpass = SECRET
|
||||
# myip = 10.0.0.1
|

# Another useful configuration value is <getcmd>, if you don't have wget

# installed (an example config for curl is given below)
