Linux cant ping my network PC's

I have 2 Win 98 Pc's connected to a hub which I have Linux connected to. My network worked fine for 4 Months, but a few days ago, I powered off my machine and I cant ping My pc's oand they cant ping My linux. The 2 PC's cant see each other. I use Roaring penguin adsl and when I first boot-up, I cant even ping my my 2 ethernet cards on My Linux box internally. Then I run my firewall script with masquerading and IPV4 turned on and I CAN see my internal ETH cards but NOT my EXTERNAL PC's. this problem happened several times before, but after a few re-boots, it fixed its-self. Please help.

you need
ether=IRQ,PORT eth0 ether=IRQ,PORT eth1
in your /etc/lilo.conf

IRQ is the relevant # as is PORT.

That way you can decide which is going to be eth0 or eth1.

Check the ethernet howto, search in it for lilo.

Thanks,

But will that fix the problem of Linux pinging my PC's and my PC's being able to ping Linux? Why is the problem intermittent. It seems like when I do shutdown -h the problem fixes itsself 50% of the time. When I do shutdown -r the problem never fixes itsself! Does that make sense?

Thanks again.

This used to happen to me, too. Now they won't ping at all, ever...
