Re: Hostname on DHCP - is there a definitive answer?

I found this blog after I did did go back and forth on the hostnames showing on my router and in nmap either as unknownB827EBC0xxxx or as raspberrypi on some new Jessie installs. I did lot of mad stuff, comapring configs, kernells, etc till I woke up this morning. I had a question stuck in my mind: ...

Re: SMTP Relay

I will need to set up the same thing to comunicate to some legacy hardware.

Did anybody try E-mail relay?

Looks like it might be easier to set up. But I could be wrong.

Re: Parallel port on RPi

@Richard, Absolutely agree. When I was a kid I used to make my board by drawing on a copper boards and used acid to remove copper. Schematics were the blueprints to make the board and electronics were pretty well described. I looked at some of the stuff Trev has posted online, it is pretty good. Def...

Re: Parallel port on RPi

@Richard.

Super, I think I will start with getting what The Adafruit page on in the link you posted has to start learning. Is that a good idea for the start?

Re: Parallel port on RPi

@Richard Does the 'lp' or 'lpr' already take care of this, could it only take to tell 'lp' or 'lpr' where to write? this is hypothetical something : $ echo "hello world'' > /dev/something_parallel_on_GPIO So what you are saying a driver would have to be written so that when lp tries to write to...

Re: Parallel port on RPi

@ Trev. AWESOME! Thanks. Meanwhile I was looking around and I also use an old PC (That eats a ton of electricity for its SERIAL PORT) and as a print server. Looks like this chip could do both Serial and Parallel. I wish I could be savvy like you guys, but that is the reason I am here to learn (from ...

Re: Parallel port on RPi

I admit I will have to read up on this a ton. Here is link I found on an example how to use the above mentioned chip MCP23017. Richard, do you know about a site or would you think about putting together a site where the implementation of MCP23017 for the purposes of printing straight from GPIO would...

Re: Parallel port on RPi

Intersting stuff. Will definitely be helpfull. In your opinion is it possible to print straight fron GPIO or the RASPI or some hardware will be required to help? PS: Thank you for help. This is a very exiting time in our time of life. I think I did not have this much fun since Sinclair ZX Spectrum a...

Re: Parallel port on RPi

Did you figure out the solution? I am a novice, but what I have in mind to learn how to do, is how to connect an older parallel printer directly to GPIO and print. I want to learn how to wire it and what else I need to learn. One thing about RPI is that it give the oportunity to learn. Can anybody t...

Re: Where to start

I am also a newbie. Does anybody know a good link or even a book where to start, read up, get ideas and excitement?
I am Linux savvy, but know almost nothing about electronics.

Re: RPi controlled central heating

Like your idea. I am a newbie and I know nothing about relays. Sorry. I am Linux savvy. What USB sensors did you use with success? I need them for the same application as you.

Thanks for help.
