Hi friends,
can anyone tell what is /etc/ppp/options file ?? why is that required ?? and where it is useful...
thanks...

According to man pppd it holds system default options for pppd and is read before user default options or command-line options. Are you having a problem setting pppd options?

why is that required ?? how that works ?? please gimme some tutorials.. to know about PPPD... and in my system... in the file /etc/ppp/options.. nothing is there except a lock written at the first line....

It's necessary because not all ppp connections are the same. As to how the options work, have a look in man pppd, all of the options are explained there. I've haven't had to manually change any of the settings since I used a modem (before cable or adsl).

Try googling for ppp tutorial - sites like http://www.linux-tutorial.info/modul...name=PPP-HOWTO may be useful to you.

Thanks for that gilead,

If i set up your Linux PC as a PPP server, other systems can connect to my system and access my resources right ??? here if my system is connected to a LAN....,the main server will be doing IP-Masquerading ???

Only once they've logged in. There's an old tutorial at http://www.pcquest.com/content/linux.../199030105.asp where they walk through setting up ppp and mgetty.

This is something I haven't done before, but it looks like the user gets their interface to the PPP daemon via mgetty - and mgetty requires them to log in. Once they've connected to your server, they should be masqueraded as your server - but again, that's what I think, not what I've done...

I'd be interested in how you go with this - are you setting up to be an ISP?

Thanks gilead...
what i am trying to do is this... i have internet connection( through broadband ethernet PPPoE) in home...and aslo my friend... now without the use of software like sharaza and lime wire as in windows.. can i connect to my friends PC using this ppp??
and also there is no static IP to our PC i think....now, how can i connect to my friends PC directly .. will PPP helps me ????

Do you both have modems? If you both do (and your friend doesn't have an internet connection), he should be able to dial your PC after you have mgetty and ppp set up.

culin · 02-06-2007, 02:26 AM

ya we both have modems.... but we are in different LAN...say he is in LAN A and i am in LAN B.. now is this possible...??? or else gateway issues comes here.. ??

It shouldn't matter what LANs you're in. The PPP connection will have its own IP address and entry in the routing table.

If you've got all the hardware (and it sounds like you do) then go ahead and try it. I can't help with the configuration, but googling for PPP howtos brings back plenty of info.

oh.. ok thanks gilead...

will try for that and come back if i have some doubts...
