Would this be a terminal server? Not sure how to phrase this.

I have a number of Pi and other ssh/telnet (yes I know, but they're old and don't understand SSH) devices on my network that I'd like to be able to manage remotely, but I do not want to expose directly to the Internet. I'd like to have a device like a Pi sitting in front with a single port open. Thi...

Re: Zoom 4630 LTE Modem - cannot get this to connect anymore

Turns out my APN had been overwritten with a similar, but incorrect one (generic m2m instead of the particular one I needed.) I think this may have happened when I tried the device in a Cradlepoint unit that turned out to be Verizon-locked. I reset it to the one indicated by AT&T support, and all is...

Re: USB<>Serial device not working after reboot.

After doing some troubleshooting, I found that the reboot was caused by a switch failure that basically hard disconnected the network booted Pi from it's drive.

I have a Pi2 running Wheezy. It's doing so because there are some custom applications that don't work correctly yet on Jessie+, so it stays that way for now.

Re: I get two ip addresses

169.254.x.x is usually an address assigned by a Microsoft-run PC when it can't find a DHCP server.

I can't be certain, but do you have something binding an alias to eth0? can you post the output of ifconfig -a?

The unit is in a remote location, so as soon as I can get to it I'm planning on doing a hard power cycle and removing the breakout from the Pi. I'll let you know the results as soon as I can.

I'm not the original author of the program, but I'll try this method out and pass it on to the author. Hopefully this should catch most of the crashes.

Here's what the program does at the end, when you ask it to terminate: except KeyboardInterrupt: GPIO.cleanup(); print "program closed out" From what I've read, this tells everything GPIO, including the I2C bus ports (and only the accessed ports) to reset to a known state, and be released for someth...

I have a program that accesses a breakout board on port 0x11 on the I2C bus, using the Adafruit I2C libraries. If the program exits normally, it runs GPIO.cleanup(), all is well, and I can run the program again with no issues. If the program crashes for some reason, the port isn't released, the prog...

The infrastructure is no problem, there's Ethernet cable everywhere I'd need this.
