Appendix C. Ancillary programs

C.1. ipacc-password

$ ipacc-password
Password: shazam!
Confirm:  shazam!
7 02150C5A11070260
$

The password can then be used in router password or router enable statements in an ipacc configuration file, or for passwords in a Cisco or Quagga router configuration. For example:

router password "7 02150C5A11070260"

Alternatively, if given a filename, ipacc-password will output one encoded password for each input line of the file. A parameter of a single hyphen causes the program to read from standard input.

WARNING: encoded passwords are not encrypted. A simple, reversible algorithm is used to reduce the risk of accidental visual disclosure of passwords to unauthorised persons when viewing configurations containing them. Configuration files containing encoded passwords must be protected against unauthorised access.

C.2. ipacc-agedynamic

ipacc-agedynamic filename count

The operation of the program is as follows. The file filename is renamed to filename.1, filename.2 and so-on up to count -1. The file filename.count and the penultimate file are merged together, and written back to filename.count, so that the most recent session in either file are preserved for each IP address that appears in either file. The original filename is re-created as an empty file.

If count is omitted, the files filename and filename.1 are merged into filename.1, and filename re-created as an empty file.
