 Posted: Mon Apr 08, 2013 3:21 pm Post subject: net.ppp0 cannot find ppp0 under udev-200, but pon works well |
 |
|
| Code: |
# /etc/init.d/net.ppp0 start
* Bringing up interface ppp0
* ERROR: interface ppp0 does not exist
* Ensure that you have loaded the correct kernel module for your hardware
* ERROR: net.ppp0 failed to start
|
/etc/conf.d/net
| Code: |
config_ppp0="ppp"
pppd_ppp0="persist
call myVPN
holdoff 10"
|
/etc/ppp/chap-secrets
| Code: |
# added by pptpsetup for myVPN
username myVPN "password" *
|
/etc/ppp/peers/myVPN
| Code: |
# written by pptpsetup
pty "pptp the.ip.address --nolaunchpppd"
lock
noauth
nobsdcomp
nodeflate
name username
remotename myVPN
ipparam myVPN
|
Also, ppp0 not in `/sys/class/net/`
However, `/etc/init.d/net.ppp0` failed while `pon myVPN` works well.

I don't see any indication udev would be related, looks more like kernel issue with the provided information.
Start by looking at dmesg if the device is recognized as a USB mass storage or USB modem, if it's recognized as a USB mass storage then I'd look at possible missing sys-apps/usb_modeswitch
But it could be anything, dmesg will tell you |

@OP : What happens if you statically build in-kernel (Select <*> and not <M>) everything ppp related, (starting from USB DSL Modem Support and behind) ?

Well, the kernel is OK with udev-197
| Code: |
# zcat /proc/config.gz |grep -i ppp
CONFIG_PPP=y
CONFIG_PPP_BSDCOMP=y
CONFIG_PPP_DEFLATE=y
CONFIG_PPP_FILTER=y
CONFIG_PPP_MPPE=m
# CONFIG_PPP_MULTILINK is not set
# CONFIG_PPPOE is not set
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
# uname -a
Linux PG-S0 3.6.11-gentoogalaxy #2 SMP Sun Apr 7 23:03:22 CST 2013 x86_64 Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz GenuineIntel GNU/Linux
|
dmesg shows nothing
| Code: |
# dmesg |grep -i ppp
[ 0.930330] PPP generic driver version 2.4.2
[ 0.933307] PPP BSD Compression module registered
[ 0.936262] PPP Deflate Compression module registered
|
Kernel should be OK.
I just switch back to last kernel that OK with old udev, still cannot see ppp0.
The difference between is only more xHCI items are enabled now.
| Code: |
# uname -a
Linux PG-S0 3.5.7-gentoogalaxy #1 SMP Sun Nov 25 10:44:24 CST 2012 x86_64 Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz GenuineIntel GNU/Linux
|
And, I deleted all udev rules in `/etc/udev/rules.d` as the news file suggested.
This may be the cause.
Also, `/etc/init.d/net.ppp0` failed but `pon myVPN` works well.

if your modem is pci, look for lspci -k to get its id, i think there some lsusb for usb device.
then look for its presence in /sys
(or you can just look where the symlink points too in the working kernel+udev couple)
for info :
| Code: | ls -l
total 0
lrwxrwxrwx 1 root root 0 8 avril 20:24 eth0 -> ../../devices/pci0000:00/0000:00:1c.2/0000:04:00.0/net/eth0
lrwxrwxrwx 1 root root 0 8 avril 20:23 lo -> ../../devices/virtual/net/lo
|
This way you could tell if it's kernel (missing the ../../devices... ref) or udev (missing the symlink ppp0 to ../../devices...)
And i didn't test it yet, but udev may (should have?) rename ppp0, so look for strange name it /sys/class/net (as you only told us you don't see ppp0 there, but didn't told us if you saw something) |

I am using VPN over ent.
ppp0 will only show up after running `pon myVPN`
So, how can I make udev to make a virtual ppp0 without running /usr/sbin/pppd from pon ?
Or, how to make net.ppp0 start without /sys/class/net/ppp0 ?
| Code: |
# ls -l /sys/class/net/

One of enp1s0, enp8s4 or enp8s5 is your PPP device? Then you can use /etc/init.d/net.enp1s0 symlink instead of /etc/init.d/net.ppp0 symlink.
OR...
Does the device have a MAC?
| Code: |
# udevadm test-builtin net_id /sys/class/net/ppp0 2> /dev/null
# udevadm test-builtin net_id /sys/class/net/enp1s0 2> /dev/null
# udevadm test-builtin net_id /sys/class/net/enp8s4 2> /dev/null
# udevadm test-builtin net_id /sys/class/net/enp8s5 2> /dev/null
|
You could use the MAC and write your own /etc/udev/rules.d/70-my-network.rules, like:
| Quote: |
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="xx:xx:xx:xx:xx:xx", NAME="internet0"
|
Replace xx:xx:xx:xx:xx:xx with your own MAC and replace internet0 with whatever static name you want to give it. Don't use kernel names like eth*, wlan*, ppp*. Pick a meaningful name yourself
that is not used by the kernel, like lan* net* internet* vpn* or such. |

ppp0 is the decive used for PPTP over Ethernet.
Since it is a virtual device, it is not in `/sys/class/net/` before net-dialup/ppp running.
I still wonder why /etc/init.d/net.ppp0 can run under udev < 200 but not in udev-200.
| Code: |
# udevadm test-builtin net_id /sys/class/net/ppp0
calling: test-builtin
=== trie on-disk ===
tool version: 200
file size: 5601550 bytes
header size 80 bytes
strings 1255726 bytes
nodes 4345744 bytes
load module index
unload module index
