Dear David;
Thank you for your e_mail and I am sorry about my late reply.
You asked for some info in your multi part answer.
2_ No. 'scoter' is not primary DNS server. But it is a cash DNS and
'scoter' and 'cowbird' can use it as DNS server.
3_ I understand that I need a special configuration on both 'scoter' and
'cowbird' to deal with both dial in and dial out connections. If you can
help me with it would be great.
4_ Currently I am using the old fashion 'uugetty' on 'scoter' to answer
the calls from 'cowbird'. I am very interested to start working with
'mgetty'.
Regarding to part 1 of your answer if the real connection thru modem still
not established other computer can not see the 'cowbird'. In other words
diald on scoter can not trigger the connection if the request come from
another computer. It's a sad but logical answer.
The reason I asked this question is, once you have a temporary IP address,
every body can access the domain using that IP address and in this case
they can introduce themselves as 'cowbird'. I need a way that 'cowbird'
and it's IP address remains taken even when I am not connected to the LAN.
Is there anyway to do this?
Sincerely,
Hassan
