[UCLA-LUG] PPPoE

Luis >self or protect my box. i'm running rh 6.2

ha. i just realized that i took out a portion of the message that 
i was actually replying to, and the above line does not say much.
too lazy to undo :) the question had to do with firewall
(if you need it)

yes. Although i believe pppoe  ( if you use rp-pppoe from
www.roaringpenguin.com) can do some sub-firewall mode. i mean,
it is some very very simple firewall support.

i havent tried it, so i dont know what it lets you do, but i 
would not count on it doing you much good. maybe someone
knows more about it.

Luis >>IP and all that.  If your dsl company gives out an IP everytime (ie.
Luis >>dynamic IP addresses), it can be much more complicated.  also, i would
Luis >>stay away from running a server with a dynamic IP because people trying
Luis >>to connect to your computer will have to know your new IP every time it
Luis >>changes (which is often).  

mostly true. I 'think' it may be a problem for mail servers, but even then
i am not sure. i havent tried running one myself yet. look at
dynodns.netor sites that provide related services. granted if you want
some production-type server, you probably cant trust those free services
not to go down, but i havent heard any complaints as of yet. mine works 
great, and DNS updates propagate very, very fast.

also, if you dont turn the server off, then i dont think pac bell has any
timeouts in place, so your IP should not change. so server would be ok.

Luis >>i do reccomment using a DSL company that
Luis >>gives out static IP's which most do.  it would make things much easier
Luis >>for your server and for the setup.

true, but there is a good chance you will have to pay up :)
at least, that was true at the time i was looking for provider. Flashcom
recently dropped price to 39.95 ( which is what i pay for pac bell now)
but when i talked to them before, they required a 2yr contract. also,
dont know if they do pppoe or dhcp.



Finally, for the original question, the only think you need to make sure
apart from your net card is that you have <taken from their page> :

A Linux system with a 2.0- or 2.2-series kernel. 
Kernel support for "packet sockets". All standard distribution kernels
   include this. 
The pppd daemon, version 2.3.7 or later. 
A working Ethernet card. 
ADSL service and an ADSL modem. 

client itself is a user-space thing, so you dont neet to muck 
with kernel or anything like that. 

i had problems getting my system setup only cause somehow i had something
weird going on with pppd/ppp kernel support versioning. once that was 
solved ( i had to wipe out my distro and reinstall for other reasons, so
this problem went away as well :) it has worked ok.

anyway, that was just my $2 on the topic. 

also, note that i havent had a chance to play with this whole running a
server on a dynamic ip thing a lot, but whole bunch of my friends do 
that as well ( dhcp/pppoe) and it has not been a problem.
