NAME
tcpquota.cf - The configuration file for the TCPQuota programs.
SYNOPSIS
/etc/tcpquota/tcpquota.cf
DESCRIPTION
tcpquota.cf contains various pieces of information used by the TCPQuota
programs. It is used by the daemon,
tcpquotad(8) to find out to which mSQL database to store it’s values
in, and which users/hosts that is grouped together. It is used by most
of the program suite, to find out where to find the mSQL server.
Variables
PROTOCOL
What kind of network protocol are we using? Availible choises
are PPP or ISDN. When using PPP, it checks for a link by
checking if there is a route on ppp0. and if we are using ISDN,
it checks the file /dev/isdninfo which contains the status of
the ISDN channels.
Example: PROTOCOL=ISDN
LOC_ADDR
Only used if we are using ISDN as network protocol, ignored if
we are using PPP since when using PPP, one usually have a
dynamic IP address...
This is the address on the local side of the link (our address).
Example: LOC_ADDR=195.100.20.3
REM_ADDR
Only used if we are using ISDN as network protocol, ignored if
we are using PPP since when using PPP, one usually have a
dynamic IP address...
This is the address on the remote side of the link (the ISP’s
address).
Example: REM_ADDR=195.100.170.187
SERVER
This is the machine/host which is running the mSQL server, could
be IP address or FQDN address.
Example: SERVER=42.42.40.42
Example: SERVER=stalin.ccw.se
CHECK_REMOTE
Should we check if we have remote connects (if someone is
connecting to us, via telnet/ssh/rlogin etc)? This is a boolean
value, true/false, 1/0 or yes/no
Example: CHECK_REMOTE=yes
CHECK_FTP
Should we check if we have remote connects (if someone is
connecting to us, via FTP)? This is a boolean value,
true/false, 1/0 or yes/no
Example: CHECK_FTP=yes
CHECK_MASQ
Should we check any computers which is masqueraded? This is a
boolean value, true/false, 1/0 or yes/no.
Example: CHECK_MASQ=yes
GROUPS
With this variable, one can group computers (masqueraded)
together, and open each group separate. For example, we have
three rooms, with eight computers in each room and one teacher
in each. If the teacher have a class in ’Using the Internet
safely’, and ’net time is included in the class fee, he/she
wants to be able to open only that room for free ’net access.
We then write (in the config file) the folloing:
GROUPS=GROUP1 GROUP2 GROUP3
GROUP1=machiavelli kaddaffi karadicz semin khomeini muboto
chauchesko baptista
GROUP2=idiamin saddam mao lenin adolf kim pinochet castro
GROUP3=cleon indbur loris wienis asper stettin gilmer stannell
This would mean that if the teacher is sitting on khomeini, and
runs the program openfw(8), He or she will open the following
computers for free ’net access:
machiavelli,kaddaffi,karadicz,semin,khomeini,muboto,chauchesko
and baptista.
USERS
This is the same as the GROUPS variable, only for user group
allowed free ’net access
Example: USERS=free turbo
LANGUAGE
What language we should use for the output. So far the programs
have only been translated to Swedish and English (with a lot of
spelling errors in the English version, I reckon :)
Example: LANGUAGE=svenska
MONEY_VALUE
What type of money we are using.
Example: MONEY_VALUE=SEk
LOGFILE
Where should we write our log file?
Example: LOGFILE=/var/log/tcpquotad.log
PIDFILE
Where should we write our pid?
Example: PIDFILE=/var/run/tcpquota.pid
NOQUOTAFILE
What file should we output to a user if he/she have gone below
the minimum amount of allowed quota?
Example: NOQUOTAFILE=/etc/msgs/no-tcp-allowed
MIN_QUOTA
What is the minimum amount of quota, before we ’cut the link’
for the user? If the value is 0, then the user can not owe you
anything, but if the value is, say, 200, then the user can owe
you a maximum of 200 <MONEY_VALUE>.
Example: MIN_QUOTA=150
RATE_QUOTA
How much does the one minute cost under the cheap tarrif. In
Sweden we have two different tarrifs, high and low.
Example: RATE_QUOTA=0.1
MIN_UID
Above what UID should we care about connects? If we set zero (0)
here, even root have to pay... This may not a good option, since
the mailer daemon, and the news daemon etc might do outside
connects. We are working on a way to make each user pay for it’s
own mail connect, but we have yet to find out a way...
Example: MIN_UID=1000
TICS
Number of tcpquotad passes an ’out’ session can be unconnected
to the database before tcpquotad gets tired of waiting and
throws it out. It is modified in relation to
’tcpquotad.PERIOD’...
Example: TICS=10
HIGH_START
HIGH_STOP
When does the low rate resp high rate begins and ends? (Hour of
the day, in Sweden that is between 08.00 and 18.00 weekdays, and
low rate on weekends)
Example: HIGH_START=08
Example: HIGH_TOP=18
HIGH_RATE
LOW_RATE
Weight for each second under resp period. What is the
difference between high and low rate? (In Sweden the high rate
is twice as expensive as the low rate)
Example: HIGH_RATE=2
Example: LOW_RATE=1
tcpquotad.PERIOD
How often should the main daemon check for connections? We have
discovered, that on a 386 one might need to have a number higher
than 30 (seconds), so that the machine is not to heavily loaded,
and on a Pentium, one can check every five seconds without any
problems...
Example: tcpquotad.PERIOD=5
Example: tcpquotad.PERIOD=30
tcp_masq_openhost.PERIOD
How often should the ’log daemon’ tcpquotatop (1) check for
connections?
Example: tcp_masq_openhost.PERIOD=10
Example: tcp_masq_openhost.PERIOD=30
