Hello to everyone. I am from the philippines. the scenario is this: I have a computer w/c acts as FEDORA 3 DNS, DHCP,SAMBA server. The SERVER also acts as asterisk pbx server, and at the same time masquerade for client computers. The connection to the internet is thru a dialup internal modem. My internal LAN is connected to e0. The second computer is a windows XP( the client computer). now the problems is this: When the two computers are connected peer to peer via cross cable, thers is no connection problem. fedora computer can ping and make connection to the client xp computer. But when i decided to connect them thru a switch/hub, thats when the problem arises. fedora can not ping the client xp, and vice-versa. The message on the client xp stated: LIMITED OR NO CONNECTION. The switch i am using is CNET POWER SWITCH(CNSH-1600) with 16 ports. iIt kinda old switch. My window O.S is a service pack 2 NEMESIS. I am loosing my head on how to configure what is wrong. Any help you can render is very much welcome. Thanks for reading this message and mabuhay! (means long liive in our native tongue).

The basic things comes first: cables.

The cables to connect 2 computers (Crossover cable - TIA/EIA 568B) are not the same to connect computer to hub (straight cable - TIA/EIA 568A).

Some switches can work with both, others no, specially the cheap/old ones.

So, my first advice is to check your cables.

Thanks for the marozsas. i did use straight thru cable to connect the fedora server with the switch, and also for the windows xp client going to the switch. for peer to peer i used crossover cable. the cnet switch inicates a green/orange on its status led. am i missing something here? do you know any issues regarding xp service pack 2 in relation to my problem? thanks.

Only that the Xp firewall not allow ping.

Try to disable firewall in fedora (service iptables stop) and in Xp. In the Xp, repair the connection. Try to ping each other now.
If not work, open a cmd in Xp, and post back the output of "ipconfig /all".

marozsa, this is what the output of ipconfig /all:

And I did what you told, disable firewall on both xp and fedora and ping each other, but with no luck.

It look's like the problem is in the switch configuration. Begin with looking at the configuration software of the switch, maybe it has some kind of blocking mechanism that prevent's the connection.

Other fact will be checking your cables, remember to use straigth-trough cables for connecting computers to switches, and crosover cables for connecting computers to computers.

Hope it helps.

how do i chck the switch if it does have some kind of blocking mechanism? yes i did what you said, plug straight thru cable from the computer to the switch but nothings change. it still doesnt work. Thanks for the reply.

In most switches you can connect via a serial or lan with telnet and configure the firmware-software, many switches have options in there like for making a vlan or firewall or something like that. You'll have to get your switch manual and give it a read for the connection method.

Hop it helps.

Hello. This is not a Question but an answer to a question i posted last may 3, 2006. This started from 2 pcs (1 computer acts as fedora server and gateway and 1 pc as xp client)i am trying to connect to a fixed configured cnet 16 port switch. fedora can not ping the xp client, and xp stated that it has limited or no connectivity. Luckily for me i did solve my own problem. I stopped all the services on fedora and gave xp a static IP address without default gateway. Wella, the server and the xp client can ping each other. one by one i started the services in the fedora server and it ran smoothly.
I wrote this message, for the intention of giving other the reference they need if they encountered the same problem as mine. I think it is my duty also as a member of this organization to contribute for the solution of my problem. Thanks to cux who responded to my message and to Linuxquestion.org.
