Re: Network stops working
Thanks you all for all your help in my problem. It's fixed. I had to force the 10baseT/UTP half-duplex connection and allow some icmp packages. Joao Fernandes To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message

I wouldnt use the NIC the cable company gave you since its most probably a pile of crap... They basically never have any hardware features, and I have had them just die on me of there own will... The reason it probably works in windows, is because you have the driver from the cable company installed for it with the correct settings set... Anyway Good Luck! Kal.

Re: Network stops working
That's interesting - I have a similar problem that also just started recently (coincided with changing my power supply but I'm sure that it is unrelated). I find that one of three things happens: 1. dhcp simply does not successfully negotiate 2. dhcp negotiates, gets an IP number and a router, but then I get 100% packet loss. (Never tried calling them to see if they got through to me.) 3. It actually works. Option 2 is what usually happens, but if I restarting dhcp enough times, I get option 3. Since I keep the connection up all the time, I only worry about the problem sporadically. So I have never tried to investigate its cause. (The ISP is att@home if that is useful. My NIC is a RealTek 8139.) Luc Morin wrote: > > Hi, > > I've been asked to clarify the topology of my system. > > Very simple setup. All I have is my home box connected to my ISP > thru cable-modem.

Re: Network stops working
Hi, I've been asked to clarify the topology of my system. Very simple setup. All I have is my home box connected to my ISP thru cable-modem. My NIC is a PCI NE2000 clone using the ed driver. My ISP uses DHCP to assign my IP, so I run dhclient at boot time from my rc.conf file. This setup has been running fine for me for over a year now. Even after my last cvsup/buildworld everything was still perfectly working. A few days ago, I started getting a situation where after a few minutes of operation (after boot), I can't reach anything, not even my default gateway (assigned by my ISP as part of DHCP). I've talked to my ISP's tech support rep, and he told me he could ping my box just fine ( 0% packet loss ), while I couldn't ping anything ( 100% packet loss ). I also noticed that even though I can't reach the outside world, I still see some syslogd messages about failed attempt to connect to my box (I have log_in_vain="YES" in rc.conf). Please see attached file for specifics of my system (kernel config file, dmesg output, uname -a, ps -ax etc...) I hope this clarifies the situation :-) Many thanks, Luc Morin uname -a ouput: FreeBSD southpark.videotron.ca 4.2-STABLE FreeBSD 4.2-STABLE #0: Thu Jan 18 18:00:27 EST 2001 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/MYKERN4 i386 dmesg output Copyright (c) 1992-2001 The FreeBSD Project.

Besides the obvious problems with your mail client, you need to provide some more info, e.g.. uname -a , dmesg and any errors generated would be helpful... I seem to remember some problems similar to this one before, you should search the mail archives, if no joy come back with more info and readable mail...

Re: Network stops working
Hi, I have tested a few more times by rebooting my box and pinging a known good host. Every time I see the same pattern. it works for a few minutes, then stops working completely.
