Re: My Debian box can't connect Internet (RESEND)
Hi Alexey, Thanks for your advice. (Remark: - I made another clean installation of Debian 3.0 on another PC with net-installer (sarge). It went through smoothly.

The first line above is 'root root' not 'root dip' Besides the file /etc/resolv.conf appeared very strange. I was allowed to make a change to this file after issuing following command # chattr = /etc/resolv.conf But after starting 'pon dsl-provider' the said file changed back to its original content as follows; search domain.com nameserver 192.168.2.1 (default content) - snip - > Add a "usepeerdns" option to your dsl-provider file.

Added "usepeerdns" to /etc/ppp/peer/provider But it could not solve the problem Still can't connect to Internet. I think the outgoing packages is searching the gateway 192.168.0.1. I made connection to Internet once (ONLY ONCE) as follows; = - Bootup the Debian box - pon dsl-provider - ping -c 3 www.yahoo.com packets received - "usepeerdns" already in /etc/ppp/peer/provider - cat /etc/resolv.conf showing search domain.com ISP address ISP address (3 entries) - deleted "usepeerdns" in /etc/ppp/peer/provider - rebooted Debian box - pon dsl-provider ISP connected, but blocked from Internet - I repeated tests several times. Occasionally cat /etc/resolv.conf showing search domain.com ISP address ISP address (3 entries) but still could not connected to Internet, ISP connected. Other times cat /etc/resolv.conf showing search domain.com nameserver 192.168.2.1 (default content) It seemed very strange to me. I have been trying to solve this problem several days without a solution. B.R. Stephen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

I ran 'pppoeconfig' again selecting not starting 'pppoe' at boot. # pon dsl-provider ifconfig showing ISP connected but the Debian box was still cut off from Internet. I took another spare hard drive and performed another installing Debian test on another PC. This time I used net-installer, sarge CD. Everything went through smoothly. However he same problem still occurred, ISP connected but cut off from Internet. Therefore I could not download packages from Debain website or its mirror sites to complete the installation. I am a little bid disappointed. I could not discover where the Debian box are blocked from connecting to Internet. B.R.

Re: My Debian box can't connect Internet
Dear Stephen, It's very odd that you can't change this file as root. The only thing I know of that would cause this is if the immutable flag is set. The way to find out is with the lsattr command: [EMAIL PROTECTED]:/etc> lsattr resolv.conf s---c resolv.conf As you don't see an "i" that means the immutable flag is not set, so no problem. Changing the immutable flag is done with the chattr command. I have heard it said that crackers do mess with the immutable flag, but it seems odd that your box would be cracked if you can't even get online. By the way, my /etc/resolv.conf has nothing in it, but it works. When I connect with the command "pon dsl-provider" a temporary address is provided. I can see that address with the plog command. The only annoyance I've had with pppoe is that I have to be root to issue the pon/poff dsl-provider commands - there must be a way around that, but I haven't found it yet. You could try running pppoeconf again and set your system so it does NOT connect to the Internet on bootup, and use the pon/poff dsl-provider command (it would be easier than reinstalling).

Re: My Debian box can't connect Internet
Yup! This is what started the sholw "consumers" threat. A common enough problem. Maybe a hundred messages so far on this and related ADSL problems since I got my Debian/Gnu/KDE installed. Still ... no ADSL. A few things you might check though: What type of modem are you using? USB ones need specific drivers, Ethernet connected ones do not. The USB driver install (even if you are not using the hardware) may have better documentation that might be useful. I just edited all the files as called out by the manufacturer of my (non-USB) moden based on their documentation (still not working). That network restart command--no one told me about that one yet! Will save reboot times to test changes. If you have saved messages, read throught these threads. There must be something in that init.d directory that needs be called to log on. This might be the only piece I am missing in this frustrating little puzzle. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Re: My Debian box can't connect Internet
Hi Robert, Thanks for your advice. The Debian box is connected to broadband via a ADSL modem with dynamic IP. I ran 'pppoeconfig' to setup the connection. Up to this point it seemed without problem, ISP connected and confirmed with 'ifconfig'. But connection to Internet was blocked. I searched around to find out whether the gateway in the network card has entry which will mislead looking to the gateway and could not find it.

Re: My Debian box can't connect Internet
Dear Stephen, You didn't say what kind of broadband you want to connect to. There would be a difference between adsl and cable, as well as pppoe and adsl with a fixed address. I'm not an expert, but I just yesterday connect to adsl (using pppoe). If that describes your situation, try running "pppoeconf" - it's fairly intuitive and it worked well for me. As for using "ping", I understand that many web sites are blocking the ping command (or am I wrong about this?). I'm using Guarddog as a firewall, and I've also got ping blocked. regards, Robert On Sat, 13 Dec 2003 00:29:33 +0800 Stephen Liu <[EMAIL PROTECTED]> wrote: > Hi folks, > > My Debian box can't connect Internet, Broadband connected. > > # ifconfig > showed connecting ISP > > I played around with following files without a solution; > > # cat /etc/network/ifstate > lo=lo > eth0=eth0 > > # cat /etc/network/interfaces > # /etc/network/interfaces -- configuration > file for ifup(8), ifdown(8) > # The loopback interface > auto lo > iface lo inet loopback > # The first network card - this entry was created during the Debian > installationauto eth0 > iface eth0 inet dhcp > > # cat /etc/network/spoof-protect > LOCAL_IPS="127.0.0.1/8" > LOCAL_IFACES="eth0 eth1 ppp0" > (Remark: having tried; > #LOCAL_IPS="127.0.0.1/8" > #LOCAL_IFACES="eth0 eth1 ppp0" > LOCAL_IFACES="eth0 ppp0" > > After each change made > # /etc/init.d/networking restart > Reconfiguring network interfaces: done) > > # cat /etc/network/interfaces.dpkg-new > # (no output, an empty file) > > # cat /etc/network/options > ip_forward=no > spoofprotect=yes > syncookies=no > (having tried; > ip_forward=yes > spoofprotect=no > syncookies=yes) > > # ping -c 3 www.yahoo.com > ping: unknown host www.yahoo.com > > # /etc/init.d/iptables stop > Aborting iptables load: unknown ruleset, "inactive". > > iptables has not been configured yet > > Kindly advise how to fix the problem. > > Thanks in advance. > > B.R. > Stephen Liu > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".

Re: My Debian box can't connect Internet
In article <[EMAIL PROTECTED]>, Stephen Liu wrote: > My Debian box can't connect Internet, Broadband connected. 1. What provider? 2. Broadband means cable rather than DSL, right? I use comcast at home, connected a debian sarge machine to a cable modem. To allow anything from going in / out, you have to activate service by connecting to a webserver to register at. Ask your service provider. I had to call 4 times before I found somebody willing to help me with doing it with my webbrowser on linux instead of insisting that they only support microsoft customers. Typically all your machine has to do is call dhcpcd or dhcpclient in order to ask the network for an IP address/DNS config etc. Just log in as root, type 'dhc' (without hitting return) and press the tab key twice to see which binaries it offers - probably dhcpcd. Just start dhcpcd and then try your ping again. DNS is the name server, so that it finds the IP for www.yahoo.com when you type 'ping www.yahoo.com'. The config happens in /etc/resolv.conf. Why do you have ppp0 - do you use a dial up modem? Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
