   We have a small (550? lumen) Sony projector.  Resolution is 1024x768. If
you aren't projecting onto a full wall-sized screen, 550 lumens is fine (for
say 1.5m diagonal). The cost of the small sony was $4300 IIRC.  Supplier was
Canberra Professional Equipment.  The 2000+ lumen projectors are in the
$10,000 range.  On the advice of other areas in ANU we bought all Sony gear.
Haven't played with widescreen inputs, but I see no reason you couldn't just
turn the lens in (as long as you aren't already projecting at maximum
width).  Light density would drop, but if you pull the curtains it should be
fine.  Total darkness not required.

Redhat 7.3 + Gentoo CDs wanted

I am seeking copies of the Redhat 7.3 and Gentoo distro's.  I live northside and
study at UC, and I'd be willing to supply blanks (or replacements for pre burnt)
Alternatively if someone is willing to lend me the CD's overnight (weekend, whatever)
I can burn them at home and return them later.

Thanks in advance,

How to Log Account Usage?

Hi,
 Now my Dialin server, using mgetty is up and running in Red Hat 7.2.
 Actually there was a bug in the ppp package that came along with the
 7.2 installation cd. check out www.redhat.com for more information.

 Now the next challenge for me is to log user account usage? Can
anybody
 help me how to do that. Till now I've not seen any mgetty help pages
 reffering to this topic. Can user accounting be managed by mgetty or I
 have to use separate account?

 help me please.....
 Thanks...

Re: How to Log Account Usage?

You can use your firewall rules to implement ip accounting. 

ipchains and iptables have packet and byte counts. 

You can add a rule (with no target) for you're ppp interface that matches all 
packets. The byte count will then give you the total number of bytes sent 
in/out on that interface. You have one for incoming (your download total) and 
one for outgoing (your upload total). 

As there is no target for the rule, your other rules won't be affected. Also, 
make sure this is the first rule in your input chain for that interface (and 
the same for output). That way, your other rules won't match and drop out of 
the chain before the packets are counted.

There's a whole bit about this at the linux doco project (tldp.org). Check 
out the network administrators guide.

You'll need to zero the rules periodically, and record the packet/byte count. 
Otherwise the counts will "overflow" at some point, and start again. cron 
should do this nicely.

Of course, you can get as specific with your rules as you like. e.g. you can 
count the traffic on port 80. Anything you can do with rules, you can do here 
as it's just a rule with no target.

If you don't know much about linux firewalls, check out www.iptables.org. 
There are some really good how-to's here that I highly recommend. Anyone 
connected to the net should have a reasonable grasp on this stuff. There's 
also how-to's for ipchains (I can't remember where though, google is your 
friend), but iptables offers some extra nice stuff.

Hope that helps,
Paul.

Re: How to Log Account Usage?

Thanks Paul.
That was a great help. With those rules I can log the account usage on
the basis of bandwidth consumend.
Also, I want to creat account usage log on the basis of connection
time.
Can mgetty log those times..ie. start and end of a sesion.

Thank you very much,
Bikrant

Unless you have 1 or 2 modems hanging off the built-in serial ports of a
PC, I strongly recommend using RADIUS.  Hell, I'd even use it then 

Running a RADIUS server gives a few benefits:

 * It handles dishing out IP settings, user authentication, and
   accounting.  You only need learn one system! 
 * The architecture supports failover/backup servers, so should
   the primary radius server go down, you don't lose out.
 * Supported by the major access servers (Lucent Portmaster, Ascend MAX,
   Cisco AS5x00 (though I think you need a certain IOS version for the
   earlier 5200/5300 models)) and a Unix server via "portslave".
 * Scales very well.  Should you need to expand dialup services, just
   plug in more dialup systems and point them at your existing server.
 * Most will store stats in a database, letting you easily grab all
   sorts of useful information.

Some radius servers you might care to check out are cistron, xtradius,
freeradius and yardradius.  All the above are apt-gettable in Debian but
unfortunately you're running Redhat, so have fun finding them, solving
dependency issues, etc. :P

Re: How to Log Account Usage?

Sounds like good advice. And I went and looked up mgetty logging and 
everything!

Anyway, if you still want to use mgetty, log files of what it gets up to are 
written to /var/log/mgetty.ttyxx (where xx is your device). Thats the default 
location anyways.

have a look at www.leo.org/~doering/mgetty/

Cheers,
Paul.

Telstra ADSL

Hi,
    It's going to take about a year for Transact to get to my suburb, so 
I've been thinking
it might be a good idea to take up Telstra ADSL. Has any body had any 
trouble with
them? would any one recommend them? is pppoe all I need, etc?

I've had good success with Telstra ADSL. I regularly get 50kB/sec
downloads, and latency seems notably less than my old modem.

My configuration use the roaring penguin pppoe client (with
a 2.2 kernel - from the Mitel SME server).

You don't get a fixed IP, but dynamic DNS works OK.

You would be crazy to run any kind of network without a 
firewall - I regularly get port-scans and code-red worm still
seems to be running around.
