The smpppd now has an accounting log of every connection.  The log is located
in /var/log/smpppd/accounting.log and has the following format:

    Row   Meaning

  always:
    1, 2  date and time in UTC and ISO 8601
    3     name of ifcfg file (without leading "ifcfg-")
    4	  "u" for up, "a" for alive or "d" for down
    5	  "om" for outgoing master or "osx" for outgoing
          slave number x (x starting at 1).

  for up and outgoing master:
    6     name of provider (UTF-8, quoted with " in C style)
    7     name of user who started connection (quoted with " in C style,
          empty if unknown, optional)

  for alive or down and outgoing master:
    6, 7  number of bytes received and transmitted

  for up and outgoing slave:
    -

  for alive or down and outgoing slave:
    6, 7  number of bytes received and transmitted (these may be
          0 and included in the numbers for the master)


Empty lines and lines starting with a hash must be ignored.

The slave enties are always enclosed within the master enties.

Don't assume that you can read the ifcfg file.  The file may not be readable
for normal users or may not exist anymore.  Just see it as a unique name.
That's also the reason why the provider name and not the provider filename is
logged.
