command-line-PATH-bug.txt

2022-07-22

Dear Sirs:

	Thank you so very much for your excellent help. My original Bugzilla report #? dated 2021-09-15-Problem-with-PATH.txt fixed almost all of the problems, but there are a few stragglers that have shown up. I made a little shell program (below) that demonstrate these stragglers: http://162.250.19.7/command-line-PATH-bug.txt.
	It would be nice if distributions included: "/home/local/sbin:/home/local/bin:" in the "PATH" command for use by programs that are compiled form source code for a specific computer. This would let these programs be backed-up by just copying "/home" and the directories under it. Since most of the programs that are installed with "apt" are generic binary files and are stored under "/usr" and "/var". Putting programs that are compiled from source code there makes it very hard to back them up.
	I have upgraded my install of "thttpd" from Acme.com so hopefully even a third or fourth grader will be more able to install "thttpd" and have their own bullet proof World Wide Web server which is directly connected to the internet. My web site is: http://162.250.19.7/ and theoretically just the IP Address: 162.250.19.7 should get one to it. The file "freedom.zip" contains all of the material. A Raspberry Pi 400 ($70 USD, Kit $100 USD) pulls 7 - 10 watts and has a built-in heat sink so is totally silent. Running a 32 bit OS limits the maximum size file served by thttpd to less than 2 GB. Using a 64 bit OS gives an unlimited file size. In a few days, My site now running on a Raspberry Pi 4 B with 4 GB RAM, will have been up on the World Wide Web for over three years, without any problems of being hacked.
	My log files are under "ac0xl/logs." and show the beating a computer connected to the internet takes and the tactics that are being used to hack web sites. "thttpd" is an industrial grade web server. Just a couple of months ago, the total number of web-server computers directly connected to the internet, in the whole world, finally went over 12 million, https://news.netcraft.com.
	Having a web server that is safe only on a local area network does not build much interest for one, when they can be building robots or video games and interacting with others, see: RaspberryPi.com and RaspberryPi.org.
	Thanks again for all of your FANTASTIC HELP! Feel free to share this information with everyone.

Sincerely,


Frank Anderson, AC0XL

# There is still a problem with the path when I add "/home/local/sbin:/home/local/bin:" to the PATH and then reboot so it takes effect! The man pages now load so that part is fixed at least in the Raspberry Pi 64-bit OS. Ubuntu might not have brought the change in. It is like the $PATH is not being followed, at least at times now. Thanks for all of your help!
