• Caller Dropped Carrier script

    From Mvan Le@3:800/432 to All on Monday, December 28, 2009 19:20:30
    Here's a short script I wrote to read in a Maximus log file and separate those annoying "Caller dropped carrier" sessions caused by internet port scans.

    Filename: proc_cdc.vbs
    Shell: Cscript, VBScript
    Platform: Any operating system with Windows Scripting Host (WSH) installed eg.
    Windows XP/2k/2k+[3,8]/Vista/7. You can get WSH for Windows9x & NT.
    Purpose: All BBS call log entries with only "Caller dropped carrier" in them
    are filtered to separate files eg. %filename%.cdc & %filename%.log.
    Assumes: The log files to be processed do NOT have *.log or *.cdc extension.
    The system for which this script was written writes Maximus log files
    to "node%1.tmp" where %1 is the node number.
    Input: Any Maximus log file
    Output: Deletes input file and creates *.cdc (for Caller Dropped Carrier)
    and *.log (Other).
