Hello,
I have two RedHat 9.0 installed machines, and I want to transfer some files from one computer to another computer thru a USB cable by using a shell script or a C program. I have a data cable (it has USB connectors at both the ends), so I can connect these two machines. I will not have a network cable connected between these machines.

Is this possible? Or my imagination is too much? Did anyone tried anything like this before? If it is possible please give me some suggestions.

Thanks
Seran

By data cable do you mean a regular USB cable or a special host-to-host cable. You might damage the PCs if you connect them together with regular USB cables.

I have a host-to-host cable. Thanks for the link.

Hi

Im doing spmething similar, or trying to.

My Host to Host cable doesnt come with a lot of info tho. The packaging says Y125D and USB-DLINQ.

From lsmod I have

speedtch 12360 0
usbatm 16128 2 speedtch
atm 41236 4 pppoatm,usbatm
uhci_hcd 32016 0
usbcore 126148 6 plusb,usbnet,speedtch,usbatm,uhci_hcd

and cat /proc/bus/usb/devices gives (edited)

Trouble is, now Im Googled out of info and answers. That or Im looking in the wrong places. My Mandriva 2006 setup wont recognise this network connection. It looks as though the system can 'see' the cable, and loads appropriate (I think and hope) driver modules. What else do I need to do for this to work please?

Any more info reqd, just ask. Thanks in advance

After a bit more Googling, I have identified my cable as a GeneLink. In the 2.6 kernels, you have to enable gl620a and usbnet. I think, from what I've read so far, its as well to enable bridge as a kernel module, because i think in order to set up the cable, you will need to use brctl (bridge-utils).

dmesg now gives me

Now all I need to do, is to find out how to write or adapt or copy a script to get the interface up.

Will post again, as an when.

Damn got the same problem.

How do you send data?
And how do you get usbnet to register it automagically?
