Im getting DSL tommorow but the lady told me they dont support linux, and that I would pretty much have to do it myself. So im just wondering if its going to be hard. Im running Red Hat 7.2 and i have an ethernet card thats set up and everything. Will it pick up and install the modem itself? Is there anythign I need to know about or should be wary of?

Depending on what your DSL provider does is the biggest factor. Search around for people with the same ISP and tack on 'linux' as a search parameter. Most likely it's Point-to-Point-over-Ethernet
in which case you'll need http://www.roaringpenguin.com/pppoe/
which should help.

--Hope this helps

dude dont worry about it....

these stupid fuck heads at these companies make it seem like going to space.

most networks assign ip by dhcp and so do router. so if thats the case just go enable dhcp and your on.

nothing more to it.

You can use roaring penguin or build it into the kernel.

I had one setup on the boat for a while. It was a piece of cake with roaring penguin.

just ran the setup program. adsl-setup

after the guy finally got his stuff to work, he said we don't support linux. I said if you just give me a username and password you won't have to.

I entered in the username and password he gave me

then ran the adsl-start command

I saw the modem light blink a couple of time and it was connected.


the software now is probably easier than that but I have not used dsl for a year.


Only thing to be aware of is that you need to clamp MSS or else the clients on the inside will need to have the mtu set to a lower number than the default 1500.

1452 is a good number

adsl is running at 1492.



clamping is probably default, however this is using packet mangling at the server so it loads the server and prevents vpn from working.

there are reg scripts and programs for setting up windows clients if you can do that.

for linux use

ifconfig eth0 mtu 1452

to set it, you do not need to set it on the server

go to dslreports.com

run this from the client inside to check for the best settings and also to get the tools to set mtu and tcp window size
it will probably tell you to set mtu to 1492, but for clients use 1452, you can set the servers internal interface to 1492 if you want, but that requires modifying the clients. the internet interface is handled by rp-pppoe

the best option is probably both

setup the server to do clamping, and setup the clients to 1452

the clients will never send a packet bigger than 1452 so the clamping will not be used.

However if a new client comes along and you do not want to modify their machine there large packets will be clamped by the server.

Again, I would leave the server internal interface on 1500 if you are not modifying all clients or some things will not get through.

this is the actual link I was refering too in the post above

My dsl provider told me they was NOT supporting linux and they was NOT supporting network too and they was REALLY NOT supporting hub,router,getaway or any network thing and they said Windows XP was too recent and they wasn't helping you if you can't get on cuz their connection tool was to sh*tty to work well on Win NT.

Strangely, I'm running slackware, on-line 24/7 trought an Hub and I share my connection with a computer running xp.

In fact they do not support anything cuz their computer knowledge stop just after they press the power button

metalhead,

You might also note that if you call and ask questions about your connection, just tell them you're windows. I was with Telocity some time back, and at the first mention of Linux the techs would get evasive and not respond! My issues weren't even with the computer but the line connection. Jeez. I thought that was just a bit tooo uptight. Just a warning. When they say they don't support it, they mean it!. But enjoy your dsl anyway!

The bottom line is if the link light on the modem is lit it's working, and if it's not it's a problem with the line or the modem. Tell them you need to get the link light lit before it even matters if a computer is hooked to the darn thing or not and they will agree.

They will tell you to unplug and reboot your computer and wait 30 minutes or some hogwash. All you need to do is just wait till the link light comes on. You will have to power cycle the modem to get it to link back up in some cases. However rebooting or unplugging your computer is nonsense.

Also tell them to give you a dialup number for when it's down. They will have no problem with that.

I had trouble when the weather got bad and had to use dialup a couple of times. Lightning storms will cause the modem to go bad.

You shouldn't have any problem with configuring DSL on Linux. I don't recall if there is any Internet Configuration Wizard in RH7.2, but there is in RH7.3. When selecting a device you just need to choose "xDSL connection" device type, then enter the other info (SP, username, password, etc.). You can even choose it to be activated whenever your computer starts.

I got it working and it is excellent!! Thanks guys
