I have a RPZ with a camera. I take pictures and save them to the SD card. Originally the files were .png and locally on the machine they worked in the program to view them. I then FTP them to another machine and they are corrupt. Looking at the files in the TERMINAL, I see them as purple files. Exis...
Forget the old commands "ifup wlan0" / "ifdown wlan0". Instead get in the habit of using "ifconfig wlan0 up" / "ifconfig wlan0 down". Or, to be entirely up-to-date, "ip link set wlan0 up" / "ip link set wlan0 down". These commands will make dhcpcd do something. I know it has been a while, but it is...
Recently I had to rebuild my machine from Jessie to Buster. I got a new SD card and flashed Buster onto the card and went about getting things working. It is a headless machine, but the HDMI port has a HDMI- Composite converter so I can get audio output. That is then sent to the sound system for pla...
I am sorry to say I don't have a magic answer. I too am having problems with VLC. But for what it is worth, I would get rid of the bluetooth part. From the terminal also try this: amixer cset numid=3 2 Then try something like: sudo aplay /usr/share/sounds/alsa/Front_Center.wav And see if that plays ...
Eventually i tried to reboot the router/AP instead of the PI, and on its return to service the Pi was available without any intervention??? Yeah, that can be annoying. I have asked about the "hotplug" option here: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=251021 That is a whole other ...
(Oh great first attempt failed.) Yes, in a perfect world that would be nice. (And easy to do.) Though I can move the RPz to another (better suited) location to connect to a monitor, the failures are random. The last time it was more than a week before it happened. I don't have a "spare" monitor to l...
It has happened now a few times and I am not able to understand how to fix the "problem". My RPz(W) is connected to my WAP. (Linksys WRT 1900acs) The RPI is headless. Every 18 seconds - or so - it sends an "I'm alive" signal back to a central machine. A few times now I see the LED on it going crazy....
/etc/network/interfaces, ifup/ifdown, the "hotplug" keyword are all obsolete . Even in Jessie. What you want is the modern way of configuring network interfaces, which is event-driven: when an interface is brought up, an event is fired and dhcpcd configures networking (see /etc/dhcpcd.conf). When a...
fruitoftheloom Thanks very much. I have a fixed point now. But reading that it doesn't cover/explain how to reconnect to the WAP if it (the WAP) goes down and back up. Or, I don't understand what I am seeing. no mention of hot-plug For setting up the WAP, that looks like the page I have bookmarked t...
It is kind of difficult to try a different "card" on a RPz(W). The "card" is part and parcel to the machine. I really don't get the sarcasm - though I am from Oz. If that is the accepted way to talk to others, then it is not really of any help to anyone. If people know things and other people like m...
I have a RPZ(W) and now and then the WiFi goes down. Yes, that is in itself a problem. Every time it goes down, the RPZ dies. Or, more so: Is disconnected from the WiFI and doesn't reconnect when it comes back up. Reading stuff there is/was a line you could put in the file that is: allow hot-plug wl...
I am NEW to this kind of OS. Though I despise windows, I am not a guru with where things are, the commands and the association of things in Debian. The RasPi is a great little machine with so much potential. I am using/enjoying it but I a now limited because of what happened. I ask for help from peo...
I know.... I've asked about this before. Something has happened and the WAP now won't come back to life. (Headless RPI 2B running Stretch) It has been there quite happily for a long time. The power was lost to it and when it powers back up, no WAP. I tried the second USB port: Same. To check the don...
Epoch1970, I don't think so. I shall investigate that. But really that isn't the real problem. It is really more that sometimes I try to log into that machine and it is just dead. I'm just mentioning this because it may be related. Neilgl, Yes, sorry. NR - Node-Red. Oh dear! Sorry. Update. No the RP...
Thanks to all. Bit more. Dunno if this is "O/T" or not, but it is part of the problem. I am running NR on that RPIZ(w). It connects (via WiFi) to another RPI which is also running NR. The second RPI is a 2B is my "main" machine for this. It is also my MQTT broker. These two machines are on 24/7. I h...
I thought the problem of the random RPZ(w) was behind me. Alas it seems to have started happening again. Could someone help me to identify which log files I need to look at to determine the cause? I know of the /var/log/system and /var/log/messages but are there any others which could/may help me fi...

I have a RPZ(W) running 24/7. It is early days but now and then it is locking up or something. I am not sure as it is headless. I have the log file and message file. Is this the right place to ask for help understanding them? I copied the /var/log/syslog and /var/log/messages file. The event happene...
