i'm really a newbie.. just a week old.. good thing i have a few friends online but they're not always online is a bad thing so one of them referred me to linuxquestions.org.. here's the problem:

i ran pkgtools and setup the dhcp through that and still couldnt connect to the network (i connected my pc running slackware to a laptop running windows xp which was using the speedtouch 330 silver usb modem) so i typed in "dhcpcd eth0" and found out that dhcp was already running and then i still couldnt connect to the internet through the network so i got the speedtouch 330 silver on the laptop and configured it on my slackware 10.2 and followed the instructions on a web site but i can't post it yet cos i haven't post 3 times..

after that it went perfectly fine.. until i restarted..now i can't connect to the internet through the dhcp network (since i got the modem) and can't connect even with the speedtouch 330 silver.. i typed in "ifconfig -a" on the prompt and these were the results:

sorry i'm trying to be detailed as possible.. i couldnt copy and paste what the real messages were so i wrote it down (a painstaking task) and typed it here on my laptop hehe .. please help.. i really am lost.. if i'm missing anything please say so..

Im confused by your post.
Is the laptop using the speedtouch modem? If so why does the linux box have a ppp connection?

Can you ping an IP (try something you know will respond like 66.249.93.104 which should be google.com)? If so the DHCP server (which I assume is the windows box) isnt passing the DNS information right. (try looking in /etc/resolv.conf to see and possibly configure static DNS by inserting the IPs of your ISP's DNS servers into resolv.conf and stopping the network interface from overwriting them on connection)

I'm even more of a newbie than you are. I'm sorry to post such a probably-dense response. But I have found that if my computer isn't connected to the network when it boots, then it can't find the network if I plug it in (Ethernet). There is probably a way to make it look, but I don't know what it is. (If it's been on the network at bootup, and I disconnect the network, it finds it again okay if I plug the Ethernet cord back in.) So, my suggestion is, make sure the other computer is on when you boot linux--and make sure the other computer's Internet connection is up. I suggest this because it sounds to me like you're getting Internet this way:

Internet->XP Computer->(hub?)->linux computer

(edited reply)
yes.. i'm confused myself.. i'll try to explain.. my internet->XP computer ->linux computer... i just connected the two with an rj-45 cable i bought.. that's how i connected to the internet before but i got tired of turning on the laptop just to connect to the internet to i decided to install the modem for the speedtouch 330 to my slackware 10.2 installation. right after the installation everything went fine i was able to connect to the internet right away but everything went crazy after i restarted.. the modem is on.. but i can't connect to the internet even if i manually type the "speedtouch-start" command in shell..so i switched the modem back to my laptop so i could write this post.. since i couldnt connect using dhcp anymore..i ran the "ifconfig -a" command and that's the output.. the strange thing is.. my modem isn't connected to my slackware pc while making this post.. and yes it's connected when it's booting.. i restart both the laptop and PC to make sure.. actually i start my laptop first then my slackware(pc) to make sure it's connected when slackware boots

unfortunately those guys working at my ISP (wouldn't mention the name maybe it might be bad) don't know anything about linux.. i asked the dept head if he could help me with it (his name is RICO <-- grrrr) hehe anyways.. he said that i'm better lucky with my XP so why change it..maybe there might be something with the speedtouchconf.sh script that's conflicting with the dhcpcd on startup?? maybe? i'm still trying to comment out the dhcpcd in /etc/sbin/rc.init1 so that i'll make the dhcpcd execute later after the speedtouch script is running..i'll post any results later
