Re: Connecting to file server on my LAN from Raspberry Pi

If you don't have Windows systems also connecting to your imac, you likely would find nfs to be easier to configure and faster, compared to smb/samba.

If, on the other hand, you do have windows computers connecting, then samba is the best choice.

Re: NAS drive will not mount on pi

Not sure if this is contributing to it, but my router has a static IP address (192.168.0.15). I assigned this IP to the pi as well. That'll kill you every time. If you were receiving mail, would you want someone else who lives somewhere else to have the same address you have? Wouldn't that cause yo...

Re: Raspberry Pi 400 Computer Room

You did not specify what level of school you are talking about, but I presume elementary or secondary. Seems to me a pi would work adequately for most of the things you would encounter at that level. I would suggest upgrading to an SSD rather than using an SD card; if your goal is low maintenance, y...

Re: WiFi Analysis

If your Pi is configured as a client, it will behave just like all your other clients - your desktop, your laptop. and your phone. You should not see it at all using that wifi analyzer. Your pi should only show up if you have configured it as an access point. And if you have done that, it won't work...

Re: Accessing raspberry through SSH

With that said, I would strongly recommend not to leave a port open for the world to find. You paint a big target on your home IP address, and invite hackers to probe around. I run a knock server ( google Single Packet Authentication (SPA) and fwknopd) that opens the port, just for me, on demand, a...

Re: Need some more info about C

Re: How to set permanent network configurations ? (Ip,Gateway,subnet mask and mac)

You shouldn't have any trouble using your virtual PI...this type of work is simple enough and all VM software (that I have used, anyway) should support it just fine. To do what you want to do, without altering /etc/dhcpcd.conf, I would suggest that you disable the dhcpd service on the RPI and set th...

Re: 2 Wifi Dongles to one Connection?

You could probably deal with the channel overlap/interference issue to a large extent by having one dongle work at 2.4G while the other is at 5G - if your router will let you do that. In that event, you don't want to bridge your dongles, but bond them. Look into the Linux interface bonding. https://...
