EXPIRE-IP-DB(1)

NAME
expire-ip-db - remove old entries from a dns-terror DB file

SYNOPSIS
expire-ip-db [-v] [-d days] [-m mark-size] [ip2host.db]

DESCRIPTION
expire-ip-db removes entries older than a given time from a DB file produced by dns-terror. This keeps the DB file from growing without bounds. If this were not done, then eventually the overhead of storing months' worth of IP address to hostname mappings could become greater than the speed benefit from having them available, and the memory image of dns-terror could become unworkably large.

OPTIONS

-d days
    Remove entries older than days. Default is 35 days, which is long enough for daily entries to last to the next monthly report.

-m marksize
    Print a notice every marksize entries.

-v  Verbose: print progress messages.

FILES

ip2host.db
    Default DB file to process.
