Mageia Bugzilla – Bug 8225 Log shorewall display "WARNING: The state match is obsolete. Use conntrack instead." Last modified: 2013-09-20 07:48:44 CEST
Sep 06, 2019 Shorewall Tutorial - James Madison University This option prevents Shorewall from being run accidentally. The LOGRATE is the number of seconds/minutes before a packet is logged after the first packet has been logged. If the value was 10/minute then Shorewall will log the packet and (60/10) 6 seconds later it will log the next connection request packet and so on. For most Shorewall logging, a level of 6 (info) is appropriate. Shorewall log messages are generated by Netfilter and are logged using the kern facility and the level that you specify.
Example: LOG_LEVEL="NFLOG(1,0,1)" Beginning with Shorewall 5.0.0, the log level may be followed by a colon (":") and a log tag. The log tag normally follows the packet disposition in Shorewall-generated Netfilter log messages, separated from the disposition by a colon (e.g, "DROP:mytag").

System: fail2ban and iptables Tweet 0 Shares 0 Tweets 13 Comments. Around the beginning of 2005 we saw an increase in brute-force ssh attacks - people or robots trying different combinations of username and password to log into remote servers. A quick search on this topic returns many references to iptables and ipchains but noone really explained how they work.
Shorewall Tutorial - James Madison University This option prevents Shorewall from being run accidentally. The LOGRATE is the number of seconds/minutes before a packet is logged after the first packet has been logged. If the value was 10/minute then Shorewall will log the packet and (60/10) 6 seconds later it will log the next connection request packet and so on. For most Shorewall logging, a level of 6 (info) is appropriate. Shorewall log messages are generated by Netfilter and are logged using the kern facility and the level that you specify. See shorewall-logging(5). Similar to LOG:ULOG [(ulog-parameters)], except that the log level is not changed when this ACTION is used in an action or macro body and the invocation of that action or macro specifies a log level. In a Shorewall logging rule, the log level can be followed by a log tag as in "DROP:NFLOG:junk". The generated log message will include " chain-name junk DROP". By setting the LOGTAGONLY option to Yes in shorewall.conf (5) [8] or shorewall6.conf (5) [9], the disposition ('DROP' in the above example) will be omitted.
