Bug#347958: Fails to establish pppoe connection
Hi, Looks like you did not already configure your ethernet connection and pppoeconf is not correctly configuring /etc/network/interfaces to raise eth1 before starting the PPP connections. I have seen a similar bug in the pppoeconf package in the latest Ubuntu release, but I do not know if this is related. It mangled in some way the interfaces file but I can't remember the details (maybe this was related to eth0 using DHCP). auto isp iface dsl-provider inet ppp pre-up ip link set eth1 up provider dsl-provider This behavior is in last releases of pppoeconf. This line is added in /etc/network/interfaces : /sbin/ifconfig $ifacenocomma up # line maintained by pppoeconf Then, this pppoeconf bug will be closed (or reassign to ppp package if you want) except you have new informations for ppoeconf.

Your pings to 193.175.81.44 are rejected by 193.175.81.253 which is on the same network, so the PPP link is working. I tried to observe the problem for about one week now. I noticed about 20% failures when trying pon to establish a connection. This is definitely a ppp problem and I wonder whether I should reassign this bug back because of the log of our discussion or open a new one. The real problem is that I can't prove this via tcpdump. What happens? 1) User calls pon dsl-provider. In about 80% this works fine, but in 20% this fails. Some ppp[0-3] devices are created in addition to eth1. 2) ping www.debian.org fails 3) Try the same as root fails as well 4) Start tcpdump -i eth1 and do pon dsl-provider as root works fine. So we have some quantum mechanics effect here: If you look at it it works but if you are not looking it might fail. Please tell me what I can do more to track down the problem.

It is a fact that I can perfectly ping 193.175.81.44 when I'm using the old ppp package but I can not when I'm using the new package. Perhaps I should try to ping www.debian.org - but I have to go to the box in question first. It was just a random IP adress I'm regularly using ...

If you will open it in ethereal you will see a first successful PPP connections, which is not terminated until later (packet 41-42), then (starting from packet 30) an attempt to estabilish a new connection which fails because the remote server is not sending back the PADS packet (because it's already engaged in a PPP session with you?), Well, that's easy to explain. From the old modem days I'm using a /usr/local/bin/pon that basically does while ! fping $host /dev/null 2/dev/null ; do sleep 2 /usr/bin/pon dsl-provider done and finally a new PPP session is almost estabilished but killed from your side still in the LCP phase.

I was able to reduce the help of pppoeconf to the real necessary part. If I use ifconfig eth1 up before the first pon dsl-provider everything works fine. This is the solution for ppp Version: 2.4.3-20050321+1, and is required after a reboot. If I stop the connection via poff and retry pon everything works fine. This was not necessary before I upgraded to latest testing in the beginning of this week - so please consider also an other package that might cuase this problem.

I also attached a stripped /var/log/syslog file which contains a first connection (using the good old working ppp package) and in the second part a failed connection using the latest ppp package. I would be happy if you could tell me what might be the problem in pppoeconf that if I understand you right created an unusable config file - at least unusable with the latest ppp package.

Bug#347958: Fails to establish pppoe connection
Package: ppp Version: 2.4.3-20050321+1 Severity: important Hi, I'm very sorry hat I'm unable to send this bug report using the ppp version in question but without a connection it is just hard to send something. So please read that this bug is concerned to version 2.4.4b1-1 of the ppp package. I just grabbed the old package from snapshot.debian.net to get my network back. The problem: In the beginn of this week I updated to the latest testing which included an update of ppp. After I tried to establish the next pppoe (ADSL) connection this failed. I verified the logfiles (grep ppp /var/log/syslog) and compared these with the output of the old ppp version but found nor relevant difference here (except the version number of the pppd daemon). I tried to reconfigure my setup using pppoeconf which worked for the first time - but failed immediately after a poff; pon dsl-provider sequence. I was not able to get a connection until I rebooted the next day. At this day I've got some kind of random connections: I tried pon several times and sometimes this worked. When I switched back to the old version (see version number in bug report) this also did not worked out of the box - another pppoeconf was necessary. I do not really understand what this script really does. I never changed my input to the script and the /etc/ppp directory did not changed after a call. But now I got my ppp working again - well mostly. Even when I switched back to the former ppp version the connection can not be established relieably after every pon. Mostly it works after a pppoeconf (which is kind of annoing because of #334361). So it might be that the trouble was not caused by ppp itself but perhaps one of it dependencies that was moved to testing together with ppp in the beginning of this week Even beeing a DD myself I have no idea about all this ppp stuff and I'm really in vain what to do here. I'm completely clueless and really need some help. I guess you will need some more information and I'm willing to provide anything that might be necessary. So feel free to ask for further information.
