Note that you can't start a long running process from udev. As soon as the udev processing is complete EVERY task spawned by udev that's still running is killed (without prejudice).

If it's NTFS mounted with uid=0 and gid=0 then only root can read files on it. You may need to use uid=www-data or gid=www-data to allow apache2 to access files.

I think it's a dead project. It's certainly cobwebware as there's been no updates at https://bitbucket.org/selectnone/raspipboy/commits/ since 6th July 2015 (five years ago).

Wouldn't it be nice if PCManFM worked the way it's designed and the design matched your expectations.

It really is a pile of crud and there must be something better out there.

I'm using a Raspberry Pi 4B and the official 7" touch display. Both are powered independently. Scenario 1: I plug-in the screen, then I plug-in the Pi. Outcome: Everything works great! Scenario 2: I plug-in the Pi, then I plug-in the screen. Outcome: The screen does NOT come on. In scenario 2, how ...

Barmen are a breed apart, they'll be doing the mental arithmetic in the same way that the guy playing darts is adding up the arrows and subtracting from 501 (or the current remaining total) as each dart is played. The ATM has counters for everything. The self-scan in Tesco is the same (it's just an ...

I have allocated 512MB to GPU.

Cut that in half to 256M.

Look in the /var/log/apache2/ logs. You should see the failure logged in there.

Is your /media filesystem FAT or VFAT or exFAT (a windows drive)? If it is then you need to change the owner (uid=) & group (gid=) parameters on your mount command. Take a look with a mount | grep media command.

Another thread where the OP didn't do any research. BTW, it's 24*365 or 24*7 (with an implied 52 weeks) not 24*7*365 (which is just less than seven years).

I wrote this today on the other thread. viewtopic.php?f=36&t=60362&p=1693904#p1693925

Can we use raspberry pi 4 4gb has a web server and run the server 24*7 in 365 days I've had one run for 365 non-stop. Current record was 150 days (until Wednesday when I had to drop the power to do some electrical work on the house). There's three of my RPi1Bs that have been powered up constantly s...

Second, why start with the largest notes and work down - the 100s, then the 50s and end with the 20s? That's the way to make change. You have to hand over the fewest number of notes and coins that way. It makes it easier for the customer assistant behind the till to make change and count it out to ...

Is your RaspiOS installation up to date?

sudo apt update; sudo apt dist-upgrade -y; sudo reboot will get you to the 4.19.118 kernel, latest bootcode and latest RPi4B EEPROM.

You need to disable the DHCP server on your Netgear router. Then run your own DHCP server (which is used to push DNS settings to client machines) on your Raspberry Pi. With dhcpd and something like this in /etc/dhcpd.conf ( not dhcp c d.conf) # Sample /etc/dhcpd.conf # (add your comments here) defau...

i don't have a custom dns in this net . there is way to change the folder with a different settings that doesn't require changing dns ?

You can test it with a line in /etc/hosts

Code: Select all

127.0.0.1 cristiangiro.it

Or on Windows in C:\Windows\system32\drivers\etc

Code: Select all

192.168.1.103 cristiangiro.it

more /etc/resolv.conf
Code: Select all
# Generated by resolvconf
search 8.8.8.4
nameserver 192.168.1.1

The Google DNS is 8.8.8.8 or 8.8.4.4.
If you can't reach that there's alternatives at 1.1.1.1 & 9.9.9.9.

I have run into an issue that searching has not helped. When I try to run "sudo leafpad index.php" It does not let me. I get a message saying leafpad: Cannot open display: Any ideas on why this may be happening? I'm connecting to the Pi via SSH. ssh (unless you're using mobaxterm) doesn't have a X ...

dude, do you honestly think that the wiringPi code is for anything else than for the RPi? The wiringPi stuff was created (back in 2012) to make GPIO programming on an RPi look like an Arduino. So the folks who were familiar with Arduinos could get a head start on their new Raspberry. How can we con...

Maybe the USB Controller is a little buggy on my board.
Can you boot from an SD card and verify that the USB ports are working.

If you have a compatible USB SDCard reader you can try a bootable & tested SDCard as a USB boot device.

I'm using default pi OS and I think it is slow. How do you define "slow"? Are you comparing performance against some metric? Is it slow to boot? Slow to use? Slow to run your programs? Slow to write files? Slow to select/update databases? Slow to serve web pages? Slow to play videos or audio stream...

That sudo command was just to get the cups compatible lpr program installed.
Thanks. I only use it sparingly and only then if advised by someone I trust!

So not me then. With my efforts today (I just could not get things working on my mainframe) I don't trust me.

DougieLawson

What's in /var/log/apache2/example.com_error.log that should tell you what's going wrong.

DougieLawson

That sudo command was just to get the cups compatible lpr program installed. It's a serious illness if you catch a dose of sudoitis, the prognosis is that you will ultimately result in destroying a filesystem when you least expect it (by sudo misuse).

Is there a specific reason for running ClamAV on a Raspberry? There's nothing it will detect that infects a Raspberry, ClamAV is designed for X86 servers sharing files with Windows users.

These days even the Windows Defender stuff built-in to Win10 is better than anything you can get with ClamAV.
