[OpenBSD 3.6] Plus de traffic TCP via pppoe - LONG

Bonjour,

Depuis ce matin, j'avais des problèmes de connexion instable depuis une
passerelle sous OpenBSD 3.6 (perte de connexion, ralentissements).
Ensuite, depuis environ une heure et demi, je n'ai plus du tout de
traffic TCP qui passe à travers la connexion internet, quand celle ci
est établie via la passerelle, alors que cette même connexion se
comporte normalement quand je l'initie depuis mon iBook. La connexion
est bien établie (les messages de contrôles LCP passent correctement),
mais aucune traffic TCP comme UDP n'arrive à passer.

La connexion se fait via PPPoE, entre un contrôleur Realtek 8139 (même
problème avec un contrôleur Winbond, pilote ne), et un modem ADSL
Alcatel Speed Touch Home.
Je n'ai eu jusque à présent aucun problème de connexion depuis que
j'utilise OpenBSD (depuis la 3.4 de mémoire), ni même quand j'utilisais
FreeBSD auparavant.

* Le comportement illustré par un ping est le suivant, le ping ayant
été lancé immédiatement après l'établissement de la connexion :

Donc là je me pose la question, à savoir quel peut être le problème.
J'aurais tendance à exclure la panne d'un contrôleur Ethernet, étant
donné que le problème se pose avec deux contrôleurs différents.
De plus, je n'ai rien touché au niveau configuration entre le moment où
ça fonctionnait et celui où ça a cessé de fonctionner.

J'ai eu le même problème il y a quelques temps sous netbsd, et j'ai
résolu ça en changeant de carte réseau.
Globalement d'après ce que j'avais pu lire à l'époque, ça provient
de carte/driver réseau pas géniaux.

Cela dit j'espère que quelqu'un aura une explication plus convaincante
à te fournir.

Quelques pistes quand même :

- que donne un netstat -a && netstat -m ? (en gros a tu beaucoup de
connexions genre p2p ?).

- je te conseille vivement le driver pppoe 'in kernel'
( disponible dans l'excellent sets de patch de jedi =>
http://www.42-networks.com/obsd_patches/jedi-diffs.tar.gz )

- dans le pire des cas vu que tu as la chance d'avoir un Speed Touch
Home va voir sur http://forpage.com et transforme le en routeur (qui
fait aussi dns, firewall, dhcp, dyndns). C'est un excellent
modem-routeur une fois patché.

Cdt,

Raf

Bonjour,

Depuis ce matin, j'avais des problèmes de connexion instable depuis une
passerelle sous OpenBSD 3.6 (perte de connexion, ralentissements).
Ensuite, depuis environ une heure et demi, je n'ai plus du tout de
traffic TCP qui passe à travers la connexion internet, quand celle ci
est établie via la passerelle, alors que cette même connexion se
comporte normalement quand je l'initie depuis mon iBook. La connexion
est bien établie (les messages de contrôles LCP passent correctement),
mais aucune traffic TCP comme UDP n'arrive à passer.

La connexion se fait via PPPoE, entre un contrôleur Realtek 8139 (même
problème avec un contrôleur Winbond, pilote ne), et un modem ADSL
Alcatel Speed Touch Home.
Je n'ai eu jusque à présent aucun problème de connexion depuis que
j'utilise OpenBSD (depuis la 3.4 de mémoire), ni même quand j'utilisais
FreeBSD auparavant.

* Le comportement illustré par un ping est le suivant, le ping ayant
été lancé immédiatement après l'établissement de la connexion :

Donc là je me pose la question, à savoir quel peut être le problème.
J'aurais tendance à exclure la panne d'un contrôleur Ethernet, étant
donné que le problème se pose avec deux contrôleurs différents.
De plus, je n'ai rien touché au niveau configuration entre le moment où
ça fonctionnait et celui où ça a cessé de fonctionner.

J'ai eu le même problème il y a quelques temps sous netbsd, et j'ai
résolu ça en changeant de carte réseau.
Globalement d'après ce que j'avais pu lire à l'époque, ça provient
de carte/driver réseau pas géniaux.


Justement, ce qui m'inquiète c'est que ça a marché des mois sans aucun
problème, jusqu'à hier.


Quelques pistes quand même :

- que donne un netstat -a && netstat -m ? (en gros a tu beaucoup de
connexions genre p2p ?).


très peu, dans les 2 ou 3 tentatives de connexions donkey par minutes
depuis l'extérieur.

un netstat -m me donne :

100 mbufs in use
33 mbufs allocated to data
51 mbufs allocated to packet headers
44 mbufs allocated to socket names and addresses

0/26/6144 mbuf cluster in use (current/peak/max)
100 KBytes allocated to network (32% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines


- je te conseille vivement le driver pppoe 'in kernel'
( disponible dans l'excellent sets de patch de jedi =>
http://www.42-networks.com/obsd_patches/jedi-diffs.tar.gz )


Je vais y jeter un oeil, même si recompiler un OpenBSD ne me tente pas,
je préfère quand même utiliser une version "out of the box"

- dans le pire des cas vu que tu as la chance d'avoir un Speed Touch
Home va voir sur http://forpage.com et transforme le en routeur (qui
fait aussi dns, firewall, dhcp, dyndns). C'est un excellent
modem-routeur une fois patché.


Yep, mais il ne gère pas les connexions IPv6 natives.


Sinon, j'ai pu remarquer un truc :

Quand je connecte la machine, la connexion fonctionne parfaitement. Et
j'ai l'impression que c'est quand le traffic commence à atteindre un
certain niveau que mes problèmes arrivent.

Ce qui est étonnant, c'est que ça ne le fait que dans le cadre d'une
connexion PPPoE, pas dans celui des connexions LAN classiques.

Bon, je viens de changer le bloc d'alim de la machine, chose que je
voulais faire depuis quelques temps, vu qu'il commençait à me faire des
misères, et depuis ça m'a l'air de tenir (enfin, chaque fois que je dis
ça, ça me claque dans les doigts dans les 5 minutes qui suivent)
