Re: I'm stumped -- cifs/smb share help

Hmm, as I said I know very little about these. I have used a Windows share in the past, but can't remember how I set it up.

Try just one more thing

Code: Select all

sudo mount -t cifs -o guest,domain=WORKGROUP //192.168.2.1/Shared\(A1\) /mnt/Shared
Hopefully the "guest" option will stop it asking for a password.

Re: I'm stumped -- cifs/smb share help

I dunno much about cifs as I the only fileserver/share I have is Linux, but could you try

Code: Select all

sudo mount -t cifs -o domain=WORKGROUP //192.168.2.1/Shared(A1) /mnt/Shared
# or
sudo mount -t cifs -o domain=WORKGROUP //192.168.2.1/Shared\(A1\) /mnt/Shared

Yes, you can make a case out of wood. People have already done just that.

Re: My laptop can't recognize the RaspberryPi SD card

I don't understand why you are running those commands. Why would the SD card/reader show on the PCI bus? The reader is a USB device, is it not? Try lsusb and see if it shows up there. Also, try "dmesg | tail" a few seconds after plugging in the card reader. You should see some messages about a new U...

Re: help my PIs send each other pictures without the interne

Mostly those are good points. Just a few comments though 1) You don't need a cross-over cable to connect two Raspis together. A plain straight network cable will work. It is also possible to do with wireless, but a lot harder to configure. One way is to configure one Pi as a wireless access point us...

Re: 24v to 12v input 12v and 5v outputpower supply circuit

It does take DC input. The "11.1~30v" is a clumsy way of saying the input should be between 11.1V and 30V DC, typically supplied by a battery pack containing 3 to 8 LiPo cells connected Serially (3S-8S).

Re: /etc/apt/sources.list

That's just showing the first "hop" of the route. It seems to get as far as your router (192.168.1.1) and then stall.

That does suggest that your ISP is blocking mirrordirector.raspbian.org for some inexplicable reason.

Re: RaspBerry Pi(e) Model C (imaginations & wants)

AFAIK the LAN8512 chip does support WOL, but it is not enabled/connected to anything that will recognise it. It would probably need an additional GPIO line to be tied up and the firmware modified to listen to that GPIO. Not really worth it, considering the small amount of power that the Pi uses when...

Something like:

The default search for the forums isn't good with such searches. You're better off using google. Try a google search on "site:raspberrypi.org wifi help", as that will limit the results to this site.

Re: How to lock SD card with the device

How about MAC ID instead of Serial number? It can be spoofed. And the model A Pi doesn't have one. Actually the model A Pi does have one. It just isn't used for anything. The default MAC address is the Raspberry Pi Foundation's ID B8:27:EB followed by the last 6 hex-digits of the serial number.

The first loophole is in step a). You are relying on the OS not to lie to you about the serial number. That isn't a real problem. It is fairly trivial to bypass the OS and get the serial number direct from the system using a mailbox call. However, it isn't hard to examine the code of a compiled C r...
