PPPoE server with accel-ppp on AC66U

[c0mm0n]

How to get a PPPoE server running ?

Hi,

I'm trying to set up a PPPoE Server on the AC66U.
- Using the latest beta firmware (beta2)
- Enabled the entware
- Installed accel-pppd

I can't get to connect and want to debug.

But I haven't found how I can get any lines of debug !?
- Looked everywhere => nothing
- Looked in path specified in the con file => nothing
- Looked in syslog => nothing
- Tried stdout => nothing
- Created the log files and gave them 777 rights => nothing

I run accel-ppd like this :
accel-pppd -c /opt/etc/acc.conf

Then is stalls nothing happens (service is running if if ps -ax from another shell).

Where are the logs ? Driving me crazy ? Any alternatives to accel-ppp ?

I've seen this thread, he gets logs...

Here's my latest conf file (simplified, also tried the bundled on, same result).

why you install accel-pptpd if it already in firmware? like pptp server

you can use
/jffs/configs/pptpd.conf to replace config
or
/jffs/configs/pptpd.conf.add to add some variables

 

[c0mm0n]

Cause i'm a noob with merlin and failed hard ?

Goig to test right now. Thanks for the input, could help someone as noob as me in the future.

 

[c0mm0n]

The /jffs/configs/ folder is empty.

Going to see if enabling ppt server helps or another service in the GUI.

/keep on digging

 

[c0mm0n]

Everything regarding the jffs folder is stated here with overrides etc...
https://github.com/RMerl/asuswrt-merlin/wiki/Custom-config-files

When enabling the VPN pptp server it triggers this :
pptpd -c /tmp/pptpd/pptpd.conf -o /tmp/pptpd/options.pptpd

So now you know where the conf files are, can have a look and can either override them or increment them (see link below).

Thanks again Andrey.

@Andrey

Are you sure I can have a PPPoE server running with pptpd service ? (trivial maybe, but I'm unsure)

 

[RMerlin]

For a PPPoE server you will need the server portion of rp-pppoe.

 

[c0mm0n]

Thanks RMerlin,

Is it built-in ? Should I install ? Compile ?
I usually know my ways but the asus/ddwrt/merlin are new to me.

I'm doing this to help people replace their ISP box using Merlin (French ISP Orange)

 

[AndreyPopov]

For a PPPoE server you will need the server portion of rp-pppoe.

why need rp-pppoe? rp-pppoe is another program?

Linux accel-ppp

I tend to agree with Andrey, I was installer accel-ppp for the pppoe server which is documented.

RMerlin you're sure I can't do that with pptpd/accel-ppp ?

My tests are negative for now, but needs more troubleshooting. I'm gonna use an ERL as a pppoe client, tcpdump and port mirror at last with a switch at last If I still don't get it.

Any help much appreciated.

If you want the big picture I'm trying to set this up

- PPPoE Client on VLAN works
- I've found how to create VLANs and bridge them
- Now *only* the PPPoE server running on vlan 835 on the LAN side.

I don't know then. I'm just surprised to hear that accel-ppp comes with PPPoE functionality since Asus uses rp-pppoe to the firmware to handle PPPoE ISPs, despite the fact they already have accel-pptp/accel-ppp.

No idea if it's available on Optware/Entware.

 

[AndreyPopov]

1. rp-pppoe.so present in /usr/lib/ppp
2. in /usr/lib/ppp also present pptp.so and pppol2tp.so

what need for accel-ppp pppoe server - pppoe module.

 

[c0mm0n]

I can't get any pope server to run...

- Using pppd I've tried to mod the conf, but it'll always behave as a client (PADI...)
- Using accel-pppd : I get it running from entware but nothing happens... no log, whatever debug I put, nothing in tcpdump, nothing...
- I even tried to use pptpd which is accel-pptp based = no luck

What puzzles me a bit is that rp-pppoe is in the sources, we have some pieces like pppoe-relay, the pppoe plugin for client... but haven't found a pppoe-server binary.
https://github.com/RMerl/asuswrt-merlin/tree/master/release/src/router/rp-pppoe

Could I had pppoe-server and be done ? Any tips how to do that ? What about the code already in the sources ?

Any help appreciated !
