Wow, guys... Ok, yeah - I think I'll give that a try too. First I'll try leaving the cable modem plugged in for about an hour, then try the setup again, see if that changes anything. Thanks! I'm sure that this thing will be up and running soon now!

 

EDIT: I was looking at that last link you gave me, MOttS, and was surprised to find under my /etc/sysconfig/network-scripts two more files than I was expecting:

ifcfg-eth0

ifcfg-eth0 (using module ne)

ifcfg-eth1

ifcfg-eth1 (using module eepro)

... I wonder if this is confusing things?

(I'm really hoping to read a message from you stating: hey, writing this from a linux machine connected to my inet server...  )
You most definately will get such a post when I'm up and running :D

I have only two files. And both of my cards are setup static (should not be your case because you are cable connected to the net right). According to *the* link (well, my last one .. too much link :!: :!: ), one of your ifcfg-ethX file should be set to dhcp (the one connected to the net). So I would put that in the config file of the card connected to the modem :

DEVICE=eth1

USERCTL=no

ONBOOT=yes

BOOTPROTO=dhcp

BROADCAST=

NETWORK=

NETMASK=

IPADDR=

And restart the network by typing as root

service network restart

and then the usual 'ifconfig' to see what is going on with the IPs and 'lsmod' to see if the modules were really loaded and ..

 

good luck

YES!!! Here's that message you asked for! I'm currently typing this on my linux box thru the lynx text browser! It turned out the cable modem wouldn't respond to anything other than the ethernet card it came with (intel etherexpress 100 PCI), which was detected automagically by Linux (no more find IO/IRQ searching to make it work)! :) :) :) This is VERY kewl... now since I have no graphical way of accessing the internet, this next part could be tricky. I need to share the internet with my home network. I'm going to first configure my other ethernet card manually (I erased all four of those ifcfg-ethN files and regenerated them automatically). I'll go ahead and run drakconf to share this internet connection (eth0 for reference :) (just in case :))) Thanks guys!

Hooray! Congrats!

 

Some extra info, in case you are interested in doing the same:

from memory, how it was at this friends place:

 

just modprobe the driver (/etc/modules.conf only gets read upon boot AFAIK) ... then

ifconfig [drivername] eth# [address] up

(hmm, try man ifconfig for correct order/syntax, but I think you have done this before...)

 

then once it is up, just connect to it with any other machine, if you have only win machines, use putty, else use ssh (make sure on the linuxserver sshd is running), then login (under normal user), start a vncsession, if you can figure out how to set it you may want to use icewm instead of kde (less resource hungry), then use vncviewer (tightvnc on linux, vncviewer.exe on win, google to find it..) to connect to the server, and voila, you have a graphical desktop that runs on the (headless) server displayed on your client pc...

 

Anyhow, maybe you already knew a lot/all of this, but in short this is the way I like to set things up....

OK... I am typing this from my windows machine through my linux server!! (HOORAY!)... but I seem to have lost capability to SSH into it. I've tried this:

 

ifconfig - internal net IP = 192.168.1.1...

 

so from Windows, ran SSH Secure Shell Client with that address, and it says "Host unreachable"

 

So, I tried the cable modem's address from eth0, and got the same result... Any ideas how to get thru this?

 

EDIT: Oh, and I'm having trouble with getting my video card to work with X (at least with KDE), so I don't think that SSH into X would work (or does it not care about video drivers?) Anyways, thanks guys!

Can you ping the windows machine from the server?

 

Other than that I have no idea..

 

Oh yeah, the vncserver doesn't care about video cards, if your pc boots without a card it can even work!! (normally pc's won't boot without though)

So that's why vnc is no nice...

Oh and you can even use it at a higher resolution than your video card would allow too and higher colour depth...

(btw it is not ssh-ing into X, you just need ssh if you have no keyboard/mon attached to the server and want to control it.. you need vncserver on the server and vncviewer on the client)

 

What if you start a vnc session on the linux machine (skip the ssh part)?

Can you connect to that?

 

I'm just guessing here, it may be that in MCC -> network (you can run this on the console too I think/hope) internet connection sharing you have to indicate that you want to allow all traffic to connect. (Don't know if this is a firewall or not, maybe just iptables..?? Don't know much about this..)

 

Oh yeah, can you do:

ps -ef | grep ssh

to see if your ssh deamon is running?

 

Also, can you ping the linux machine from the win machine?

If not, somehow the linux box is just still refusing all connections, you won't get far if it doesn't respond to ping....

Nope, can't ping it (I get a reply, but it says "Destination port unreachable." I think the firewall is stepping in the way :(

 

Yeah, I can see that sshd is running... just not responding :(

 

EDIT: I also can't ping my internet address...

HEY !!!!!!!! congratulation man !!!!!!!!!!!

 

So if the modem works with the ethernet card it came with, this is because your internet service provider gives internet access according to the network card MAC address. This is the 'HWaddr' number of the card when you type 'ifconfig'. For example, my eth1 MAC adresse is 00:EE:B0:00:F2:D7 (see below). So put back your ISA card, bring it up (type 'ifconfig eth0 up') and type 'ifconfig'. Nothe the HWaddr and call your ISP about that. Forget about that if you want to leave the PCI card .. :lol:

eth1      Lien encap:Ethernet  HWaddr 00:EE:B0:00:F2:D7

         inet adr:192.168.1.1  Bcast:192.168.1.255  Masque:255.255.255.0

Ok, so to resume what is going on --> You can access the net from your Windows box that is connected to the second ethernet card of your Linux box (ie, you enabled Internet Connection Sharing from drakconf). Right? However, you are not able to access your SSHD server that runs on your LInux box from your windows box. Right? If I'm right with those two sentences, then you can't because when you enable ICS on Mandrake, that installs Shorewall (a firewall). By default, Shorewall blocks everything. Ie, you will not be able to ping the LInux box from anywhere (internet and lan) and vice versa. This is secure --> YES. Anoying -> NO! .. if you can deal with that.

 

SSH with Shorewall

If you want to access your ssh server that runs on your Linux machine from your LAN (not from the net !!) then add the following line to /etc/shorewall/rules and restart Shorewall.

ACCEPT  masq    fw      tcp     22   -

You can restart Shorewall by typing as root.

service shorewall restart

Now if you want to access your ssh server that runs on your linux machine from the internet also (you should not want that for security reason), put that line in /etc/shorewall/rules and restart shorewall

ACCEPT  net     fw      tcp     22      -

Basically, Shorewall works in Zone. Your linux box is 'fw', the internet is 'net' and your lan is 'masq'.

 

VNC with Shorewall

First, you have to install VNC. Type as root

urpmi tightvnc-server

now, as your normal user (not root!), start the vnc server by typing

vncserver :0

It is going to ask you for password, give it one. Now let's enter some stuff in Shorewall so that you can access the service. Enter the following line in /etc/shorewall/rules and restart it (service shorewall restart).

ACCEPT  masq    fw      tcp     5900   -

if you want to be able to access your vncserver AND ssh from your lan, you can combile the two lines as follow:

ACCEPT  masq    fw      tcp     22,5900   -

Don't forget to restart Shorewall!!!. Now try to access the vncserver in windows. Well, start by downloading the viewer from there--> http://www.realvnc.com/download.html (you don't need to fill your name and such. Just select 'Windows 9x/2000/NT/XP (x86)' and clic 'Proceed to Download'. Now download the 'x86 Win32 - viewer program only'. You don't need the whole thing.. only the viewer). Now in Windows, double clic the .exe and enter your Linux box IP (that should be 192.168.1.1) and add a ':0' at the end. So you should enter 192.168.1.1:0. Now clic ok. YOu should be prompt for the password you entered when you started the vncserver.

 

Have fun!

Thanks MOttS and aRTee! I'm up and running, and I've moved the server to its (now) permanent position with no keyboard/monitor/mouse. Everything seems to be working great! Thanks for your help!

WOUHOO!! Finally !!

 

Will you contact your ISP about that nic (the ISA one that doesn't connect) ?

 

Also, I'm wondering, did you decide to control it with VNC or SSH or both? Did you play with Shorewall?

 

What did you do.. ???

 

I want some info .. I want some info .. I'm a Drunken Penguin waiting for some info :mrgreen: :mystismiles: :mystilol: (I just discoved those nice Javascript !!)

Well, at the moment, I'm logging in with pure SSH... I did a urpmi tightvnc-server and came up with nothing... tried it with just vnc, hoping to come up with something similar but misspelled, but nothing popped up :(. I'm thinking this is odd...

 

I did something else tho, that may affect it:

 

urpmi.removemedia -a

urpmi.addmedia --distrib Online ftp://csociety-ftp.ecn.purdue.edu/pub/man...ndrake/9.1/i586

 

This added three CD's, but I'm finding that even tho the RPM's are listed in the RPMS folder, urpmi doesn't seem to find them :(
