Hello everyone,
I was using a modification to AuthGeneric.pm that uses finger to
count simultaneous-user,
but had to trash it because the output of finger truncates the
user name and because we have
valid user names in the format [EMAIL PROTECTED] I rewrote it
to use snmpwalk, but
had to trash that also because response times were too slow and I
was getting too
many timeouts. So now we're considering AuthbySQL.
The following excerpt is from the archives.
I'd like to go over this because we are thinking about using
AuthSQL (with mySQL),
but I have hesitated because I didn't fully understand how
Radiator went about
checking the integrity/consistency of the database.

We have users that have a Simultaneous-Use of more that 1. In
that case, isn't it
possible to have existing multiple records in the database with a
the same NASIDENTIFIER and
NASPORT, but with different ACCTSESSIONID (I'm thinking that
ACCTSESSIONID is
the same as the SessionID reported with finger. Is that
correct?)?

present.
How does the RADONLINE table get rebuilt after a disconnection?
During the time a connection was not available only
Simultaneous-Use would be affected?
During the time a connection was not avaiable does Radiator then
directly poll "all" of
the NASIDENTIFIER/NASPORT combinations (using finger for
example)?
Thanks in advance.
