Re: How to execute installed program

Wow! THAT brought back memories!! I am a long-time fan of Pascal... going back to the days of Turbo Pascal in the early 1990s... late 1980s? Anyway.... I hope the following will shed light on the discussion above. Most of what I'm going to say was mentioned at some point, but I hope the following wi...

Re: free pascal / lazarus

9 Aug 2018... a simple... sudo apt-get update sudo apt-get upgrade sudo apt-get install fpc sudo apt-get install lazarus ... was all I needed to get a usable Lazarus 1.6.2 up and running on my RPi 3 b, with 16G SD card, Raspbian 9. An entry to launch Lazarus just appeared in the Programming category...

Re: Permissions issue?

k-pi... very helpful...thank you. I hadn't known how to find out what groups pi was part of. And the article very clear, very helpful. Your encouragement gave me the energy to struggle on. First I found http://www.auctoris.co.uk/2012/07/19/gpio-with-sysfs-on-a-raspberry-pi/ ... a good discussion of ...

Permissions issue?

I think I have a "permissions" issue. I created a new user... I didn't want to do everything in user pi, that being an intruder's first port of call. My "alternate user" will be, I hope, as powerful, mostly, so LIMITED protection, I know. But maybe "a hassle too far" for the intruder. I then install...

Re: Static IP- Why... How

(new material added to this post, 7 Aug 2018, 3pm New York time) One way to get a "static" IP is to configure it in your router/DHCP server. You can usually associate the interface's MAC address with a particular IP address and then you don't have to change anything on the Pi. I think my router prov...

Re: Static IP- Why... How

Thank you, bgrundy and others. The router is marked "Motorola Surfboard SBG6580. The interface, via 192.168.0.1 says "Arris SBG6580" The wonderful Google managed to find the right document even though I missed out the S. Search string BG6580 forward by MAC address https://arris.secure.force.com/cons...

Re: BASIC password questions

Thank you... and all you say makes sense. (Apart from one nit I will pick.) However, I DO want to run a server that will be visible across the interent... hence my caution. (And I still find the fact that one can change the user pi password with the GUI without knowing the old password poor design.)...

Re: Static IP- Why... How

Thank you, rpdom... and thank you Arris/Motorola for a good router, with good documentation both in item and online. It seemed like such a good answer!!! (Never solve something, when you can go around it!) But. MY router's "pass through by MAC address" feature doesn't allow binding to a LAN IP addr....

Thank you, grk... For others reading this, I think the guide he meant is... https://www.raspberrypi.org/documentation/configuration/security.md ... which is good.

Static IP- Why... How

Newbie here. Environment stated in signature... I THINK I "need" my Pi to use a static IP. I am building a web-server in a home environment. It will be on my LAN, accessible to WAN via the magics of NAT and DYNDNS. Without a static IP, how does NAT know where to redirect incoming packets for the por...

Pi as webserver- security

Yes, I'm an idiot. No, I am not a completely inexperienced idiot. I'm new to Pi, but want to set one up as a webserver, open to "the world". It won't be my first Apache server, but a long shot. But will be my first Linux Apache server. I want to be "secure". I was wondering if it would be a good ide...

BASIC password questions

New to Pi and Linux generally... old to computers. 4 Aug 2018 I put Raspbian 9 (Stretch) on a Pi 3 B (ver 1.2), and did apt update, apt upgrade. In the GUI, I can change "the" password... without having to authenticate myself with the OLD password. Seems a bit of "back-door" for bad guys! (At no sta...

Not a question... a report of "how to", I hope. Maybe spare the next person. Inspire the programmers. HOURS spent by me, new to Pi, old to computers today. Wonderful experiences initially... then tried to connect my Pi 3 B, ver 1.2 to my Wi-Fi. (Yes, did sudo apt update, upgrade... about 1pm New Yor...

Re: Lazarus, GPIO and 1-wire

I've done 1-Wire on a Windows machine, using Lazarus and the Dallas TMEX SDK... http://sheepdogguides.com/lut/dstl2hello_ds18b20.htm I know others did work for many years on Linux + Delphi, and Lazarus is "just" a "free Delphi". With PCs, instead of using a bit on a bank of GPIO pins, a lot of the "...
