OK, there's RH 6.1 on 2.2.13. Let's take a look at /var/log/messages: Dec 2 13:28:48 pentium kernel: age....

Do you know where are these strings from ? I'll tell ya. It's all from my mail fetched by fetchmail (via PPP). OK, these were strings but we have also sth like this: Dec 13 22:24:38 pentium kernel: 40 21 4C BB F4 6F 5F DD @!L..o_. Dec 13 22:24:39 pentium kernel: C4 41 74 3F BD 54 47 B9 .At?.TG. These in turn look like some kind of binary dump. Apparently not only mail fragments land in my logs. It seems that entire net traffic is affected.
You have options "debug" and "kdebug 7" activated for your pppd. Turn off debug, or at least decrease kdebug to 1, which should be enough for debugging connection initialization.
There's no need for sniffer in this case ;) That's not good when some net packets are dumped to system logs, is it ? Is it a bug ? If so, is it known to kernel developers ?
It's not a bug, it's a feature. Cheers, --------------------------------------------------------------- Andrei D. Caraman phone: +40 (1) 2050 637 Sr Network Engineer fax: +40 (1) 2050 655 Mediasat SA
