Installation +~~~~~~~~~~~~~~~~~ + +Install BOPM as usual, please see the BOPM documentation for details. +Afterwards adjust the following configuration parameters that are important +for ngIRCd: + +a) BOPM "IRC" section: + + 1) Set "server" and "port" accordingly, + + 2) adjust the "oper" line to match an [Operator] block in ngircd.conf, + + 3) change "mode" to "+ci" or "+c". + + 4) Set "connregex" to the following string, everything in one line(!): + "\\*\\*\\* Notice -- Client connecting: ([^ ]+) \$([^@]+)@([^\$]+)\\) \\[([0-9\\.]+)\\].*"; + and comment all the other "connregex" examples (prepend a "#" character). + + 5) Set "kline" to "KILL %n :Open proxy found on your host!"; for example, + and comment all the other "kline" examples. + +b) BOPM "scanner" section: + + Make sure you configure a valid "target_ip" and "target_port" for the + configured scanners to test. And please note that you CAN'T USE the port + of ngIRCd, because ngIRCd doesn't send any banner message by default! + + So you need a service what sends a banner, so for example POP3, SMTP, + IMAP, or SSH daemons should work ...
