Many Hosts via few Modems

Hi world,
i try to get data from several stations via modem.
Of cause there are more stations than modems.
A problem occurs if more request are made that modems available.
Is there a daemon that can handle several modems ? any ideas ?

If the data is transferred periodically in batches, uucp is
ideal. If it's more "live", then I don't know...

UUCP would be the last resort because i need IP based services. I have
experimented with diald, looks promissing i hope he can do it.

Oh, I missed that part of the spec. ;)

So you want to use a pool of modems to do demand-dialing of PPP
connections?

What direction does the connection go? - Do those stations dial into
Your server, or do You want to dial them?

In the former case, why not get Your server online via Your local ISP
(for a specified time, perhaps, so that the remote stations then use
that time frame) and have the stations connect to it via their
respective local ISPs. You need to tell them Your IP, though, which
You can do with one of those dyn-dns providers or upload it to one
web site which the clients will wget.

In the latter case above, You could use the modem to only signal
them that You want a connection, and in turn those remote stations
will connect via their ISP. For this they won't even have to pick
that call up - if they see that it comes from Your server, they can
reject the call and dial-up automatically.

One advantage of this is that You actually save costs, especially if
those stations are spread over a wide area. Two calls to Your local
ISP are often less expensive than one "regular" dial-up line.


Cheers, Jack.

Wow. I remember uucp. Last used it about 8 years ago. Do people really
still use it for data transfer these days?
