 Posted: Sun Apr 02, 2006 6:29 pm Post subject: pppoa with router in bridge mode: how? |
 |
|
I have an ethernet router (roper flynet), the connection works fine but I have some problems when I try to open a lot of connections at the same time (ex. pinging all the list of game servers with xqf, file sharing, etc), so I want to use the router as a modem, and do the pppoatm on my pc.
First of all, I have set the router in bridge mode, setting vpi, vci etc. Then i edited my /etc/conf.d/net
| Code: |
config_eth1=( "dhcp" )
dhcp_eth1=( "nodns" )
#ppp
config_ppp0=( "ppp" )
link_ppp0="/dev/null"
plugins_ppp0=( "pppoa" )
username_ppp0='*****'
password_ppp0='*****'
pppd_ppp0=( "updetach" ) |
The first two lines are what is needed to connect with the router in router mode, I added the ppp0 part. Next, I run /etc/init.d/net.ppp0 start and I get | Code: | # /etc/init.d/net.ppp0 start
* Starting ppp0
* Bringing up ppp0
* ppp
FATAL: Module pppoatm not found.
* kernel does not support PPPoATM |
If I run make menuconfig, I see no option to compile a module called pppoatm (I am on amd64). Anyways, i emerged ppp with the "atm" use flag and it installed a file called /usr/lib64/pppd/2.4.3/pppoatm.so
Ehm. I have no clue, basically  |

I suppose that I should patch my kernel to support pppoatm, but where do I find the patch?  |

There is no kernel patch required. ppp with the "atm" USE flag provides the "pppoatm" kernel module, which you already have. The part you're missing is actually loading the module, it sounds like:

But | Code: | # modprobe pppoatm
FATAL: Module pppoatm not found.
|
| Code: | # locate pppoa
/usr/lib/pppd/2.4.3/pppoatm.so
/usr/src/linux-2.6.15-gentoo-r5/net/atm/pppoatm.c
/usr/src/linux-2.6.14-gentoo-r4/net/atm/pppoatm.c

| Oops, I forgot, there's the PPPOATM kernel module in the standard kernel. Do a "make menuconfig", press "/" and search on pppoatm, to see its details and dependencies. For more info on the kernel modules, see speedtouch. |

Yes, finally I found how to enable pppoatm support in the kernel (first enable atm in the networking section, then pppoatm appears in the device drivers section).
The problem is that it doesn't seem to work  when I start ppp0 I get no error output, but the connection doesn't work. Isn't there a way to get a more verbose output to see what is wrong? Maybe using the pppd command instead of the ppp0 script... |

Change line to:
| Code: | | pppd_ppp0=( updetach debug ) |

Adding the debug option didn't change anything (unless the information got logged somewhere).
How am I supposed to tell ppp that it has to use the router connected to eth1? If I was using pppoe, I would just put link_ppp0="eth1"; but in ppp.example they say to use link_ppp0="/dev/null" for pppoa (and putting eth1 there actually gives an error), so how can I specify it?
I'm wondering if it's actually possible to use pppoa with an ethernet router in bridge mode, all the guides that I found refer to usb modems... |

You should see more info on the screen, and more entries in /var/log/messages. Perhaps it's failing before the more verbose messages would even start  |

PPPoA connections cannot be established over an Ethernet link.
Probably you configured your router to act as a RFC2684 bridge, but this scenario works if and only if your connection is PPPoE. |

Ah. Ok, no big deal, I'll just keep using it in router mode |
