Good day!!!
My home pc is obtaining an internet connection
through a dial-up modem. And as for this, I'm using
ppp. On my analysis, the ppp program residing in my pc
is connecting to some sort of an authenticating
server, am i right? Aside from the PPP, I've read the
portion in freebsd handbook regarding dial-in/out
services but I couldn't figure out how the process
works. Now, what i really wanted to do is to allow my
friend to log-in remotely to my pc and run some
applications like vi, mpg123 etc or even use my pc the
way I'm using it (just experimenting and of course I
would definitely want to do that too).
These are the questions that are constantly floating in my mind:
1. If I have a modem connected to a phone line, is it possible to let my friend dial from his pc my telephone number and then let FreeBSD answer the call, and authenticate him by some sort of a login prompt?
That would be pretty much what a lot of ISP's do, wouldn't it? IIRC, there's a section of the PPP chapter in the FBSD Handbook that mentions, perhaps explains well, this item. I've not yet tried it, YMMV.
2. What process would this be? Will I use some sort of ppp server and then he uses his ppp to dial my telephone number?
I guess so, see above.
3. And If ever he will be connected to me successfully, is it possible for me to still dial to my isp knowing the fact that he is using my modem to connect to my pc?
Not unless you have two modems. And two phone lines.
4. And how about ssh? Knowing that we are not in LAN,
if we both connect to the internet, is it possible for
me to login to his pc and vice versa, using ssh by
specifying his ipaddress? How will the process be?
WIll he be using some sort of ssh daemon listening to
my request?
Yes, should be, if ports are not blocked and if sshd is enabled in /etc/rc.conf on his machine.
================================ You need not specify the specific details and configuration files, just the hints about the processes.
I've asked these questions because this would be very helpful to me now that I've got my first job working in an actual IT environment.
And that would be all.
Thank you very much for the time.
Welcome, hope it helps. Not much of answer, really.
