can't modprobe ppp_mppe

Message

I get the following when I try to modprobe ppp_mppe:

[~] root $ modprobe ppp_mppe
FATAL: Error inserting ppp_mppe (/lib/modules/2.6.20-gentoo-r8/kernel/drivers/net/ppp_mppe.ko): No such device
[~] root $ ls /lib/modules/2.6.20-gentoo-r8/kernel/drivers/net/
bsd_comp.ko  ppp_async.ko  ppp_deflate.ko  ppp_generic.ko  ppp_mppe.ko  ppp_synctty.ko  pppoe.ko  pppox.ko  slhc.ko  wireless

Any idea what I am missing?

did you compile the kernel with PPPOE support as module ?

Try this first to see if it works.

modprobe ppp_mppe force=1
lsmod

to list loaded modules ( or modprobe ppp_mppe.ko force=1 and then next lsmod )

Also "insmod ppp_mppe.ko force=1" you might have to with or without the .ko try it as on wants it one way the other the otherway you get the idea.

Not sure but "rc-update add net.wlan0 default" where the net.wlan0 is replaced with apropriate text for your device is also a option but not sure about this try to google for it.

A crude way is to " nano -w /etc/modules.autoload.d/kernel-2.6 " and then just add the "ppp_mppe" to the file this will load the module during start up , then you do not have to modprobe or insmod it at all.
Just reboot and it works.

Unknown symbol in module, or unknown parameter

This looks like a defective module or busted one.
Might work with a newer copy of this or older or alternatively try one of the other ppp out there.

Could be lucky and find it in the live cd /dvd if you have one

I tried to find a copy and attach it for you but I looked in my system and the oldest I have is kernel 2.6.21-rc2 mm-sources and it is not there. SRY

The name might have changed as well or be part of a new combined generic type module as this seem to be the current thinking in the kernel 2.6.22+ mm-sources

Out of ideas here.

Hope this help

I'm joining the thread because I have the exact same problem. I've been using ppp_mppe for some time, but I just noticed that it's failing to load during the boot. As I remember, this was very easy to enable in the kernel config, make, install, and modprobe with no issues.

I'm thinking that it's a kernel config issue, but I'm not sure what.

here are my config for PPP

CONFIG_PPP=y
# CONFIG_PPP_MULTILINK is not set
CONFIG_PPP_FILTER=y
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_BSDCOMP=m
CONFIG_PPP_MPPE=m
CONFIG_PPPOE=m
# CONFIG_PPPOL2TP is not set

Are you having any issues with sha1 loading during boot? Check the dmesg log.

kurtg · Post by **kurtg** » Wed Apr 30, 2008 3:22 pm

Okay, refer to this: http://gentoo-wiki.com/HOWTO_Set_up_a_v ... encryption

And, get your settings right. I had sha1 built into the kernel. I changed it to a module and did:

modprobe sha1
modprobe ppp_mppe

And, it loaded. I'm amazed that my Verizon wireless was working without mppe, but I'm sure it will be much faster now.
