"Updated bootloader for Raspberry Pi 4" download link is bad.

I was just browsing the announcements section and noticed that the google drive link in this post is bad and leads to nowhere.
The bad download link is the third link in the post at https://drive.google.com/open?id=1hrnzA ... 7_9_kkq3Jm.

Could an admin please fix this issue? Thanks!

Re: Wordpress (wp-cli): Unable to import file. Reason: The uploaded file could not be moved to wp-content/uploads.

I don't know anything about WP, but these ?'s occur to me. What are the permissions set to right now? sudo ls -al What happens if you put sudo in front of the command? I suggest you try this with just one filename. Bob Inside the wp-content folder the output of ls -al is: drwxr-xr-x 5 www-data www-...

To instantly turn WIFI off or on from the command line use either the wpa_cli commands OR the rfkill commands as in this thread: viewtopic.php?f=29&t=240796

Re: Internet speed of Pi 4 and speed test from command line

In theory both the Wireless AC and Ethernet should be capable of Gigabit speeds. Wireless has more overhead, though, and of course there are range, interference and other losses to consider, so in actual use Ethernet will likely be faster. However, it also depends on your ISP speed. I'm only on 100...

Re: Can't ssh into raspberry pi from internet unless 0.0.0.0 Listen address is in sshd_config

No worries. By the way a Match directive can be used to limit access as per the way you had originally imagined. MaxAuthTries 0 Match Address 192.0.2.0/24 MaxAuthTries 6 Where 192.0.2.0/24 is the CIDR address of the network of computers you wish to connect from to the Raspberry Pi. A single IP addr...

I think you misinterpret the parameter ListenAddress, have a look here: https://www.thegeekstuff.com/2011/05/openssh-options/ I finally figured out that you are correct on this. Here I thought that ListenAddress 0.0.0.0 was incorrect because (i thought) it allowed all external ip's to connect via s...

1) What is the expected internet speed for the Ethernet as well as Wi-fi connections for a raspberry pi 4?
2) Is there any recommended or easy way to do an internet speed test from the command line on a headless Pi server?

No, nothing to do with web servers. You should use full upgrade as it does a better job of ensuring all packages are updated correctly.

Also, you can install lynx and go to a service like https://canyouseeme.org/ and check one port at a time.

If you have a machine outside your network you can do a more detailed scan using nmap.
