Re: [newbie] local lan problem
Hi Ian, I'm pretty new to the whole network game, so forgive me if my questions are totally ignorant. But why is there an entry for its own IP address (192.168.0.2), and why is the "Genmask" 255.255.255.255 instead of the NIC's netmask of 255.255.255.0?

RE: [newbie] local lan problem
As far as I can see, everything looks ok. Of course, that's what you said but it doesn't hurt to see the output. When you said "On the hub side the light never did come on showing that there was a connection." this could indicate that you may have a dead port on the hub or be plugging it into the uplink port. If you are using the uplink port you need a cross-over cable. Have you tried plugging the LM box into one of the working ports Windows is using? When you ping, do the hub lights blink?

RE: [newbie] local lan problem
When pinging from one windows machine to another the lights on the hub do blink. Also, I am not using the uplink port on the hub for the linux machine it is being left open for possible future expansion if we can get this problem figured out. And yes, i have tried a port on the hub that i know is working under windows. In fact i tried every port on the hub with no success. I even went and unplugged the cable from one of the windows machines immediately after i used it to ping to ensure that the network was working and then plugged it into the linux machine and still got nothing. I also tried networking only two of the machins together with a cross-patch cable and linux still cannot ping out to the windows system and windows still cant reach the linux box. I also did a bit of further experimentation and reformatted the harddrive on the linux machine, setup two partitions, one for swap with 100meg and the rest in root and went through and reconfigured everything from scratch. Still getting the same problem. BTW, i did a development/expert installation and setup lan network during the installation and PPP for the isp after the instal. Network card and all were identified fine and setup went smoothly. Could this be something on the windows machines that is preventing them from seeing and communicating with the linux box? Dunno how this could be though since they are both running win98se and a tcp/ip network which works fine from windows machine to windows machine. I appreciate all the assistance by the way folks, its nice to know that there are people out there who are willing to help when these problems crop up. Still banging my head, Ian K.

RE: [newbie] local lan problem
I am using static ip addys on the local network, ppp connection to the isp is dynamic. linux machine is 192.168.0.2 and the windows machines have 192.168.0.1 and .0.3. netmask on all machine is 255.255.255.0 I do not have any other network cards in the machine, 56k modem that is external off of ttyS0. PPP works fine btw. Just the local net isnt doing anything. I setup the local network during installation of LM7.1 as i have seen several people post that it is usually better to do it then and my own personal experience has been that its also easier to do it then as well. I did not setup internet connection during installation though, again in accordance with advice that has been posted here in the past. hostnames are all as follows and seem to be setup correctly: 192.168.0.1 - windows - comp1.possumtrot.net 192.168.0.2 - linux - comp2.possumtrot.net 192.168.0.3 - windows - comp3.possumtrot.net Many thanks in advance, Ian K.

Are you using DHCP or fixed IP-s? Do you have an other netcard in your linx box? Check hostname and IP addresses.

He also wants the linux machine to handle IP masqing. Installed LM7.1 on a HP Vectra series 5 machine that he had purchased off the internet to use specifically for Linux. We then put a realtek 8029 PCI network card in, installed LM7.1 and all appeared to be good in the world, until Trying to access anything on the local net is impossible. 100% packet loss, etc, etc. Currently on the lan there are two other machines both running windows 98 and then the LM7.1 machine. Both of the windows machines can see and talk to each other fine but they cant see the linux box. I double and triple checked all the system settings and everything seemed to be fine. Drakconf detected the network card, linuxconf showed that all the values i had entered for IP Addy, netmask, etc were fine. Thinking this might have been caused by a bad cable we tried three other cables with no results and also tried every free spot on the hub with a known good cable from one of the windows machines just to make sure that there wasnt a bad connection or something in the hub. During bootup it shows that eth0 is starting up ok and ifconfig reports that everything seems to be there and working fine as far as i can tell. I am completely lost at what to do to fix this problem and would appreciate any and all advice. One thing i did notice was that when the cable was unplugged from the network card in the linux box or the hub the light on the card showing that the network connection was present went off as you would expect it to. When we plugged the cable back into the hub or the card it returned just like everything was working normally. On the hub side the light never did come on showing that there was a connection. The hub is listed as being *nix compatable and I am using a similar realtek 8029 card in another linux machine at my own home with no problems. Linux machine info in case this helps...
