The 802.11 standard leaves multicast/broadcast rate selection up to implementers. So that means it's probably up to the card/firmware/driver of the WNIC you're using. That said, hopefully your WNIC is smart enough to not try to send multicasts or broadcasts using a rate that's not marked as a Basic Rate. The Basic Rate set is the set of rates that all ...

I just stumbled over a similar issue. In my case I forgot to make the directory on the server writable for the user that I was logging in with. You can try making it group writable for your users: $ chgrp users /mnt/TimeMachine $ chmod g+rwX /mnt/TimeMachine

If I were you, I'd do the whole thing from the pi (assuming you have spare USB ports). Instead of dding the partitions, dd the entire disk to a new SD card via a USB adapter. Lets say the SD card via USB is mounted on /dev/sdb (you can check this by looking in dmesg when you insert it - make sure you get the whole disk device name, if it says there is a ...

How about forgetting all the things happening and just reading the output of dmesg, looking for a significant line happening just before the login prompt is shown (or possibly something specifically triggered/printed by you)?

I finally realized what happened. So the setup at my apartment setup goes from my raspberry pi -> my router -> apartment's own router/switch -> internet. So I figured out I wasn't able to port forward incoming traffic because the incoming traffic first hits my apartment's personal router/switch before it hits my own router! I have no access to this so I have ...

Similar problem I had some time ago. My solution was editing /etc/resolv.conf file by adding nameserver 8.8.4.4, and by restarting interfaces using /etc/init.d/networking restart. It works for me.

There are a number of places where your start-up command may be set. The following command should check most of them: grep -i screen /etc/* /etc/*/* /etc/*/*/* /home/*/.* /home/*/.*/* /home/*/.*/*/* One of those directories should contain a file referring to your program.

I ran into this problem after upgrading my server to F21 from F20. Disabling the firewall altogether let Kodi find and mount the NFS shares, but I was uneasy about having no firewall at all on the server. I've done: firewall-cmd --add-port 1024-65534/tcp --add-port 1024-65534/udp --add-port 111/tcp --add-port 111/udp Which opens up everything above the ...

To answer this question So when I try SSHing from the outside world through my router, it doesn't know where to go because we have a shared IP address. I have no idea how to deal with this exact situation. You need to assign a specific port on your shared IP address to port-forward to your Raspberry Pi's port 22. How you do this depends on your ...

The fact that you get an IP address obtained via DHCP means that there is another DHCP client active on your Raspberry. You can check how many clients are installed by running the following command: dpkg -l | grep dhcp In my case (Raspberry Pi 2 image from 5th May) I got: ii dhcpcd5 6.7.1-1+rpi1 armhf DHCPv4, IPv6RA and ...

There are actually two parts to this: 1.First, in the file /etc/samba/smb.conf, in the [global] section, the first two lines must be: workgroup = WORKGROUP NetBIOS name = TheNameOfYourPi (if the name of your workgroup is not WORKGROUP, change the first statement accordingly). Make sure that the file /etc/nsswitch.conf contains a line like: hosts: ...

The other way is to use: vcgencmd display_power 0 vcgencmd display_power 1 That's it. This is more efficient way. It doesn't require all the framebuffer reinitialization and doesn't change the resolution. Mainly, it is quicker than tvservice. At first, it returned an error, but I updated the firmware at RPi with rpi-update and after a restart- it ...

I found this raspberry pi specific problem was discussed in this issue with some workarounds. The framebuffer driver on the pi does or did not implement the appropriate ioctl FBIOBLANK to set the monitor to video off. The workaround is to use the tvservice command to switch off power to the video signals, and eventually the monitor should turn off. ...

Install the x11-xserver-utils package to get the xset command. Then you can use it to force the DPMS signals to the monitor to on or off. You may need to set the DISPLAY variable in the environment. Eg: DISPLAY=:0 xset dpms force on sleep 10 DISPLAY=:0 xset dpms force off You can do something like this in python. Poll every second. Remember if you have ...

Install the Dell printer on one of the Linux machines - I'm almost certain you'll find support for the printer in Linux. Then you can access the printer over the network, using Cups from Linux machines, or using Samba on the Windows machine. I had a similar problem time ago, where the Windows machine didn't have a driver (anymore) for a Epson ...

One tool I have used successfully (not on a pi though), is xcalib from the package of the same name. You can use it to change the gamma, eg: xcalib -gc 1.1 -a You can repeat this. To cancel use xcalib -clear Another useful option is making the whole screen reverse-video: xcalib -invert -a It is intended to work with icc profiles, but I have only ...

On the Raspberry (I am assuming you use Rasbian), hdparm must be installed, sudo apt-get install hdparm and then you must reboot the RPI in order to allow hdparm to interface itself correctly with udev. sudo hdparm -I /dev/sda will print all of the known characteristics of the device. It is long, and unwieldy, but very thorough. You are ...

By default the Raspberry Pi is running a firewall which blocks connections originating on a subnet to which it is not attached. These rules are in /etc/network/if-up.d/secure-srm (they may be in another file if you are running a different image). You need to add a rule here to allow the ssh connection.

Well, I could not find the problem, or the solution, but on some forum found a workaround. The below is the code, modified to log out events and work as a simple cron job. (credits to original code author to be given once I find that post again.) #!/bin/sh echo "---------- START ----------" >> /home/pi/wifiScriptRunLog.txt date >> ...
