I have downloaded one script from internet which some parts are making confusion which are: #################################################### #----Create logging chains-----# ##These are the logging-chains. They all have a certain limit of log-entries/sec to prevent log-flooding ##The syslog-entries will be fireparse-compatible (see http://www.fireparse.com) #Invalid packets (not ESTABLISHED,RELATED or NEW) $IPTABLES -N LINVALID $IPTABLES -A LINVALID -m limit --limit $LOGLIMIT --limit-burst $LOGLIMITBURST -j LOG --log-prefix "fp=INVALID:1 a=DROP " $IPTABLES -A LINVALID -j DROP ##################################################### I am having following confusions. What is LOGLIMIT What is LOGLIMITBURST and What is --log-prefix "fp=INVALID:1 a=DROP " How can we only block mns messenger and yahoo messenger? How can we block all communications except www. Please help me out. Best Regards Salman __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
