Hello William, William Shu wrote:
Hi,I have secured a network cable (rj45 heads) to link a laptop directly to a desktop machine which has *no* access to a network. The desktop has TWO network cards and an rj11 socket (for telephone). The heads of the network cable have been rewired so that a switch or hub is *not* used. The technician tested the cable by pinging between 2 Windows XP machines, but knows nothing of linux and unix-based machines. Unfortunately, when I do a ping from laptop to desktop or vice-versa, I get the message "Destination Host Unreachable" (See sample output below). (I know next to nothing about networks and so I hope the questions below still make sense!) QUESTION 1: How should I go about having the desired peer-to-peer connection, without trying to use an Internet Service Provider, or start managing a local area network. I understand linux is a "network operating system" and so nothing special needs to be done. That is, the desired service (ftp, ssh, etc) is requested and used, if it is set up on both machines.
If you are connected with a crossover-cable (or have a network card that support crossover simulation), you have to only setup IP addresses of the same local vlan. For example 192.168.0.1 for your desktop interface and 192.168.0.2 for your laptop. You should be able to ping each other without having a route.
QUESTTION 2: How can I install a wireless router on the above
desktop, which has a modem card, but must not be linked to
either the telephone or the internet!. The router (a TRENDnet
TEW432BRP) has a windowsXP and requires:
* A Web browser: Internet Explorer (5.0 or above) or
netscape Navigator (4.7 or aove),
* Computer With network adapter installed
* Broadband internet
* Installed cble or DSL modem (Statitc/Dynamic/PPPoE
connection)
What should be the purpose of this wireless router? To connect the laptop using wifi to your desktop?
As Connie said, please provide us with the output of following commands: # /sbin/route -va # /sbin/ifconfig -a #And also, drawing a schema of your idea of the network would be useful. If you're new to linux world, I recommend you good documentation at http://tldp.org/ -- it helped me a lot when I've started with linux.
