No internet on Slackware 11

m4rk5 · 08-26-2007, 11:02 AM

Hello everyone,
after the weekend of trying to figure out why there is no internet in my PC i decided to ask help from you. I'm using Slackware for about 4 years and i know about Linux all i need to use it normally, i mean that i'm not advanced Linux user. So here's the problem:

I have internet which demands Right MAC address, IP, NetMask, GW, DHCP, DNS names. On windows it is enough to specify MAC address and it gets all other (though DHCP i guess) Earlyer i just had to edit /etc/rc.d/rc.inet1.conf and everything were good, till i installed Slacware 11 to my laptop. I also changed kernel to 2.6.21. I'm not sure, but i think that internet wasn't working with old kernel also. I also used netconfig, but the same result. When linux loads eth0 is down. I tried to "up" it in rc.local, but no results. Through konsole it's done without problems. When i plug in internet cable a small download starts (about 3-4 kB/s).
P.S. during boot the line "dhcpcd: MAC address = 00:10:a7:27:51:b8" hangs for about minute, it changes MAC.

here's my lspci:

sorry for such a long post, only wanted to give more information, and for bad english.

Thanks in advance.

You definitely need to straighten out your interface configuration here.

Code:

# Config information for eth0:
IPADDR[0]="84.32.242.208"
NETMASK[0]="255.255.254.0"
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]="84.32.39.199"
HWADDR[0]="00:10:A7:27:51:B8"

Here you are telling it to use both a static IP and DHCP, which obviously it cannot do at the same time. You are then specifying a completely separate IP as the DHCP hostname, which is supposed to be the name of your computer, not an IP.

As for changing the MAC, there should be no reason to change this at all. If you are dual-booting Windows and Linux, or at least had Windows installed on this same machine previously when you were online, then the MAC is going to be the same between them. Even if you had another MAC, just turning the modem off and on a few times would be enough for it to connect with the new MAC.

well, i tryed to use static IP, eth0 showed up and pinged to my IP (that raised my mood

), to all other: 100% loss.
I also used DHCP. Result: connect: Network is unreachable. Maybe i don't know what to specify at DHCP_HOSTNAME. Buti don't have that information, all i used earlyer is:
MAC 00:10:A7:27:51:B8
IP 84.32.242.208
Sub Mask 255.255.254.0
GateWay 84.32.242.1
DHCP Serv 84.32.39.199
DNS Servers 84.32.38.10
84.32.38.11

I don't have windows, i'm posting from other PC, Slackware 10.2 and everything works fine here.

I recieve internet trough LAN card, not modem.

Thank you

If your ISP is using DHCP, then that is what you should have set in inet1.conf, remove all of the other static references. You don't need to specify DNS, gateway, subnet, or IP when using DHCP; that is what DHCP is for.

Certainly your NIC must connect to something. Do you have an Ethernet cable that runs between your home and your ISP's offices?

Quote:

This would seem to indicate that you have been using Windows to connect. If it was not on the current machine, then on what machine was it being used on? Where did this MAC come from that you are trying to duplicate on the Slackware machine, perhaps most importantly, are you inadvertently setting the MAC of multiple computers on the network to the same thing?

m4rk5 · 08-27-2007, 12:57 AM

yes,i agree that if i'm using DHCP i don't need to specify IP, GW and etc. But what can i? all i can do is USE_DHCP[0]="yes", because i don't know what to specify in DHCP_HOSTNAME. sorry, internet is not my strong part. As you said DHCP server IP do not fit here, it should be String, right? Should it be my computers HostName?

Yes i have, my ISP runs cables from the basement, then it comes to switch, one cable goes to me and other to my roommate.

The situation is like this: we have three computers here, and two lines. One line is roommates (he's using windows) and other line is mine (using slackware 10.2), this spring i bought notebook, so i thought that if i change MAC on my notebook, and set everything like in Slack 10.2, when i plug-in My cable, i should get internet, i'm not using both of them with internet at the same time.

But the most interesting thing, that i would never believe that connect internet to slackware is so difficult, it never gived me so much trouble, usually about 3-5 minutes. What has changed? I fear that when i installed new kernel i didn't biuld-in some packages or modules. As this is the major thing i've changed.
