I still do not believe that ppp connections on grex's modems is
a good thing. it's just going to lead to someone setting up
a proxy of some sort on grex, etc.. to bypass these restrictions, or
make it possible for someone to dial into grex and send a few
thousand spam e-mails

re #24, I cannot telnet from anywhere to grex, I can only telnet from grex
to somewhere else, as I have no other ISP besides grex. I will be very upset
if I cannot continue to dial in to grex (by phone) and access websites. I
have accessed a lot of websites in connection with the bbs conferences. I
If I could only access websites via grex by telnetting, I would have to pay
for some way to telnet to grex rather than using this money to donate to grex
(I have let my M-net account lapse and given the extra money to grex instead).
Please do no assume that everyone can telnet to grex, or use backtalk.

Once again, keesan, we *are not* going to take away anything we currently
have.

Thanks, I will stop worrying about it and keep supporting grex. (Just don't
assume that everyone telnets to grex, the phrasing worried me.)

Jared raises some valid concerns. We spent quite a bit of time discussing
them at the staff meeting.
I'm not overly worried about somebody setting up a proxy server on Grex. The
kernel blocks should prevent that. Using Grex as a spam relay is a much more
serious concern. I'm hoping Marcus will make some changes to sendmail to
limit how much mail can be relayed off the SMTP server from the dial-ups to
some reasonable amount, which should catch mass mailings and stop them. If
not, I would not support offering POP/SMTP access from the dial-up PPP
connections.

Keesan, if grex were to set up ppp on the dial in lines, you would still
have the choice of connecting the way you do now as has been pointed out.
You would also be able to configure your computer to initiate a PPP
connection to grex's terminal server and then telnet from your PC to grex.
No other ISP would be needed. Just some software on your PC including
TCP/IP stack, PPP dialer and telnet client. All of those come with
Windows 95 and are available for older versions of Windows but probably
not for DOS)

Something that ought to be pointed out regarding mail on m-net, is that
m-net has had a number of serious bungle-ups with their mail software.
(I seem to remember at *least* one 3-month outage, of internet mail.)
That means many people who might otherwise be using m-net for mail, have
gone elsewhere. One of the comments we've consistently gotten from
people who use grex, is that they use and like grex because mail is
particularly reliable for them here. Most of those users are non-m-net
folk, so that means grex is enjoying the positive side of a reputation
and m-net the negative side. That, in turn, means comparing mail
experience between m-net & grex is something like comparing apples and
peas. They may both be sweet fruits, but that's about where the
similarities end.
Someone could spam the internet today by using newuser to create an
anonymous account, then running "mail" from a shell script a few
thousand times. If this became a problem, then we'd have to get
caller-ID, and perhaps deal with the FBI or other law enforcement
bodies. Fortunately, internet spammers work differently - and grex is
not a particularly attractive vehicle for most spammers to use when
there are so many more attractive bases of operation. One of the
thoughts we did have regarding making "ppp" not so attractive for
spammers, was to require the use of passwords when using "ppp".
So far as a "proxy server" goes, the proxy server would be bound by the
same internet access rights that the person would normally have from
grex. If they're not a member, the proxy server wouldn't be able to
make smtp connections elsewhere. If they are, then the proxy server
could indeed be used to access elsewhere on the the internet - just as
the person could have done before by running that application directly
on grex. I could be wrong, but I just somehow doubt many members would
care to do this.

Plus proxy servers would be relatively easy to detect and kill.

I'd like to point out that M-Net _does_ have pop3 - as Grey installed
the Pop3 patch I wrote, (and caught a teeny logic-bug ;-).
It's working fine and has SERIOUSLY cleared up the trouble we were
having: users checking for mail _far_ too often; and, users that are
both forwarding AND using pop3..
The patch has a #define for a time-limit (currently at 15 minutes).
What it does is:
1) Look at the users homedir for a .forward - summary abort if
found (disallow pop3 if user also forwards);
2) Look at the pop3-file - summary abort if it's YOUNGER than the
programmed time "window".
That's it.. In one day, we cleared a megaload of pop3 mail, and the
total of pop3 mail now hovers around 74 blocks at any given time.
Ask Grey for more mail-info - I just wrote a logical patch.

Oh, drat - sorry to dual post...
Note: it took me a day to puzzle out the proper place to embed
the tests - it's a simple once-line patch once the 'slapper' is
compiled..
sorry, 'bout that.

I haven't put this subject on the board agenda. I felt that it needs
more discussion before the board tries to make a call on it.

M-Net's mail problem was 2 years ago. Both M-Net and Grex have such
a high churn rate for non-members that I really doubt that a mail outage
that long ago would have any effect now on people's perceptions.
Grex has a much higher number of users than M-Net has, but
a smaller number of *conferencers* and lower activity in the conferences
than M-Net. So Grex has a much heavier e-mail load than M-Net.
I like the idea of a PPP trial period!

The whole idea makes me nervous, but I think at this point if staff felt it
could be controlled to keep us from becoming a "hotmail/juno" clone, I'd vote
for a trial period.
It would be convenient...

(In my experience, Grex is much higher profile than M-Net. That would explain
the larger user base and higher percentage of mail users, because the vaste
majority of people on the internet want email but not conferences.)

I am strongly in favor of trying out local PPP services as an
experiment. I don't expect us to be overrun with local users, but I
think it could increase telephone line usage somewhat.
I would very much like to see POP supported over that service. It would
be best if it were done from a machine dedicated to serving POP and
perhaps other mail-related functions.
I am fence-sitting on the internet-wide POP issue. I don't really
believe in the doomsday scenario, and it does have certain advantages
over what we are doing now. I wouldn't hear of it, even as an
experiment, until mail processing were done on a separate box. Once
we're in that state, I am still a bit uncertain, but lean towards trying
it.
