rp-pppoe 3.10-2 problem.

x33a · 2010-01-17 03:57:50

hi folks

after the recent upgrade to rp-pppoe, a few issues have cropped up.

firstly, i have the following entries in my crontab:

56 07 * * * /usr/sbin/pppoe-stop
57 07 * * * /usr/sbin/pppoe-start

pppoe-stop works fine, but after 1 minute, pppoe-start fails to connect, and i get

Timeout waiting for PADS packets

if i manually use pppoe-start, it connects fine.

secondly, i see these in my log (only started showing after the upgrade)

pppd[2756]: Couldn't increase MTU to 1500
pppd[2756]: Couldn't increase MRU to 1500

though it doesn't seem to affect the connection.

one thing i noted is that previously, on pppoe-stop, there was this entry in the log

pppoe[1937]: Sent PADT

but since the upgrade, PADT isn't being sent anymore. could it be the reason for the reconnect failure?

could someone please help me out.

I experience pppoe reconnect problems since the upgrade, too. Sometimes it takes several attempts to connect after a pppoe stop. There is nothing useful in the logs however.

It seems stopping pppoe again in such a case does help to reconnect again. But I did not elaborate on this yet.

I have downgraded to the previous version rp-pppoe 3.10-1, and this has solved the problem for me.

Can you please have a look into /etc/ppp/pppoe.conf and search for LINUX_PLUGIN. If there is set /usr/lib/rp-pppoe/rp-pppoe.so, can you please remove it and try again if it then works?

I have set this to the pppoe.conf file to use the kernel mode plugin in rp-pppoe. Maybe this cause the errors. If it really is, then I have to change this and not to use the kernel mode plugin.

@ ise,

just tried that and it worked. now it is exhibiting the older behaviour (which is good).

here's a comparison of the logs:

with rp-pppoe 3.10-1

pppd[1915]:pppd[1915]: pppd 2.4.4 started by root, uid 0
pppd[1915]: Using interface ppp0
pppd[1915]: Connect: ppp0 <--> /dev/pts/4

pppd[1915]: Cannot determine ethernet address for proxy ARP
pppd[1915]: local  IP address xxx.xxx.xxx.xxx
pppd[1915]: remote IP address xxx.xxx.xxx.xxx

with rp-pppoe 3.10-2 with LINUX_PLUGIN=/usr/lib/rp-pppoe/rp-pppoe.so set:

kernel: PPP generic driver version 2.4.2
kernel: NET: Registered protocol family 24
pppd[1916]: Plugin /usr/lib/rp-pppoe/rp-pppoe.so loaded.pppd[1916]: RP-PPPoE plugin version 3.10 compiled against pppd 2.4.4

pppd[1916]: remote IP address xxx.xxx.xxx.xxx

and finally with LINUX_PLUGIN=/usr/lib/rp-pppoe/rp-pppoe.so not set:

pppd[2251]: pppd 2.4.4 started by root, uid 0
pppd[2251]: Using interface ppp0

Ok, thanks for testing this. I will release a new version this evening without the config changes. Then everybody has to set the LINUX_PLUGIN on its own if he wants it.

bernarcher · 2010-01-19 06:42:54

Just confirming: Disabling LINUX_PLUGIN works here as well.

ise · 2010-02-01 17:24:15

Sorry for the long delay.
Fixed in package version -3 in [testing]. Please test it.

damjan · 2010-02-01 22:50:01

there's also the plugin /usr/lib/pppd/2.4.4/rp-pppoe.so (from the PPP package) you can try that too.

Hallo Daniel :-)

I'am quite new to Arch and found after the install a notice about the moved kernel-mode plugin in my pcaman.log. I was wondering and so I do a search and found this post and these commit.

+  #sed -i 's/LINUX_PLUGIN=/LINUX_PLUGIN=\/usr\/lib\/rp-pppoe\/rp-pppoe.so/g' ${pkgdir}/etc/ppp/pppoe.conf

So far I understand was you trying to replace "LINUX_PLUGIN=" with "LINUX_PLUGIN=/usr/lib/rp-pppoe/rp-pppoe.so".

But I think searching for "/etc/ppp/plugins/rp-pppoe.so" instead should solve the problem and you can change the log message to something like "...was changed" if needed. (or is it possible to test if it was found an only to print the message if yes?)

Besides I'm wondering why it is needed to modify the config at a fresh install rather than to ship an updated file.

Please don't become angry if it was the wrong place to ask for that issue, or that I'm not ship a ready to use patch.

Best Regards, Lothar
