Abuse logins from Pi account?

Tom Tengdin
 

Since I put my Pi on the network (running direwolf) I am getting abuse
emails from my ISP.

They claim that user pi is trying to login to other systems.

Anyone have any ideas?

Tnx,

Re: Original TNC-Pi and RPi2 or RPi3??

Dick,

I’ve used the original TNC-Pi with both PI2 and PI3. As it only has the 2 x
13 way connector you have to be slightly careful when aligning it with the
PI.

I just dug out my old TNC-Pi "Rev. 1.1 2/2013"there andwant to try it with
either my RPi2 or RPi3 boards.  There have been some changes to the
connector on the later RPi boards since the original,  I don't want to do
any damage if pinouts are wrong.  Are  there any potential problems?  I am
considering mounting the TNC-Pi via a ribbon cable not directly to the RPi.

The Raspbian Stretch availability announcement (and the comments in the
thread following) suggests possible workarounds, and imply an upgrade
should now fix the issue.

https://www.raspberrypi.org/blog/raspbian-stretch/

If you read the above it also explains how to regain control without
hard powering off (and risking file system corruption).

As I do not use the GUI on stretch I cannot comment further on the
accuracy of this information.

Look at my other post.  If you still cannot make it work, please be a bit more specific with what your problem is and I might be able to help.

Good luck.

Re: FW: Problem opening port in YAAC

Joseph LaFerla
 

OK, I am answering my own question so that the solution may be made available to others.

The port was open all the time but it was not obvious.  The port is indicated on the menu bar by a black square which does not change colour if the port is open or closed.  I was misled by that.

Hello Joseph,

 
I am new here just having bought a pi3 and a tnc-pi2.  I am having trouble opening the serial tnc port.  I configured the port as a Serial-TNC in /dev/ttyAMA0, as described in the tnc-pi2 manual

Did you disable the bluetooth overlay and redirect the Broadcom physical serial port to the /dev/AMA0 port?

   http://www.briandorey.com/post/Raspberry-Pi-3-UART-Overlay-Workaround


I did run the pitnc_getparams test which confirmed that then port is properly created

Did you get a proper response such as the output shown here?
--

            ./pitnc_getparams 1 0


         Using Serial port /dev/ttyAMA0

            PIC Software Version           0

I also tested the port using xastir and I was able to open and close the port.

Meaning it was working on 144.390 and you were receiving APRS objects, etc?

I am new here just having bought a pi3 and a tnc-pi2.  I am having trouble opening the serial tnc port.  I configured the port as a Serial-TNC in /dev/ttyAMA0, as described in the tnc-pi2 manual.  The baud rate is 19200 but when I test the port by pressing Test Port, I only get a black screen with no output.  The port is configured as Kiss only.   I have not yet connected a radio but I don’t think that matters.  I did run the pitnc_getparams test which confirmed that then port is properly created.  I also tested the port using xastir and I was able to open and close the port.  I must have done something wrong with YAAC?

 

I also set up an APRSIS port which is working fine.  It is only the serial TNC that cannot open.

I don’t know what I am doing wrong. I would appreciate any help.  Thanks in advance.

New Debian ax25-tools package update broke the mkiss utility (and others)

David Ranch <dranch@...>
 

Hello Everyone,

Just a heads up but in a recent set of Debian 9.1 / Stretch package updates. some critical AX.25 tools have been broken.  Specifically,

   ax25-tools 0.0.10-rc4-1+b1


The issue is that these new versions makes the kissattach, mkiss, and potentially kissnetd, net2kiss, and 6pack, utilities segfault due to enabling GCC PIE extensions (position-independent executable) .  This is evidently the new default in Debian 9.0 / Stretch but not all packages were rebuilt with it enabled before the distro version was released.  They are catching up now but unfortunately, this is causing issues.  I'm also investigating ax25-apps's ax25ipd, Direwolf, and tge Xastir programs for possible issues as well. 


Below is the observed behavior with the mkiss program:

   Segmentation fault      (core dumped) $MKISS -s 19200 -x 1 /tmp/kisstnc > /tmp/unix98

The proper Debian folk have been notified and they already have a proposed fix which is being reviewed:

   https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=878322


Hopefully these fixes can be applied and rolled out before other Debian-derivative distributions pick them up.  Until then, you can downgrade this package for now and things will resume working:

Re: New Raspberry Pi server for hams

kb9mwr@...
 

Well since I was the guy saying that was too much.  I will say the same for the TNC Pi and AMBE boards.  I have none of the above.

Direwolf and other soundcard based TNC's work just fine, some times better than a hardware based one.

https://github.com/wb2osz/direwolf/blob/master/doc/Raspberry-Pi-APRS.pdf

And DSD and op25 provide what I need to deal with AMBE.

It boils down to how much you plan to use any of the above I suppose, and how much money you are willing to sink into something for how much you will use it.

But I am not seeking plug and play.  That is not what ham radio is to me.  It's a place to learn and hone my skills.

Re: New Raspberry Pi server for hams

Howard Nurse
 

Thanks for your excellent questions, David.  Yes, you've given me a good start on a FAQ!  

You are certainly right about how amazing the price is for the RPi.  You only have to take a look at quantity pricing to see how little margin there is for dealers.  One wonders how the Amazons and Adafruits of the world could survive if they only sold RPi boards!

--The sound chip is the Cirrus WM8731.  You can see more at this link:


--Yes, the chip uses the standard Linux ALSA drivers.

--The board is connected via 12C.

--PTT uses an opto-isolated PTT switch controlled by GPIO pin 13.  The GPIO pin is fixed.  There is also a circuit to provide power on control for the Elecraft KX3 which requires a voltage pulse applied to the PTT connection.  Note that the RigPi Keyer also has a PTT connection controlled by the same GPIO pin or from the K1EL WinKeyer chip.

--The third 3.5 mm connector provides a direct stereo input path to the audio chip.  It is designed for I/Q processing for Panadaptors, but should work well for high speed digital.  The output transformer can be easily jumpered to provide a direct output.  We might be able to find room to add a physical jumper to bypass the output transformer.

--The middle connector is for Audio Output.  The connectors on either side are for Audio In and I/Q Input.

--There is a multi-pin header on the board to allow audio and PTT connections that use the standard set of radio cables provided by MFJ.

--Current plans are for MFJ to provide a box for the RigPi including room for the two boards.

--The RigPi Keyer board is set up for stacking with long headers.  The RigPi Audio board must be on top of the stack.  Additional boards can be added so long as the Audio board is on top.

Re: New Raspberry Pi server for hams

Ronny Julian <k4rjjradio@...>
 

I have to ask the group what other Rpi based system is out there that is truly plug and play for this.  My vision now dictates that with some exceptions I cannot solder cables and boards anymore.  Even if it did not I am quite used to the notion of a $100 Motherboard and $600 in stuff to make it work in alot of different areas.  I think the answer to all those well thought out questions will enable many people to build their own stuff yo work with this hardware as it goes along.

I sure did not hear this "That's too much" talk for the TNC Pi or the AMBE boards when you can buy a TNC-2 for your Pi at a Hamfest for $10  and the AMBE chip is Only $20.  

These are the first boards.  Crank up the cottage industry and get the copies out there (6-9 months after the software hits I'm sure it will start)  Lady Ada puts out a new Featherwing seems like every week and still sells true Arduinos alongside them.  There is room here for everyone.

Hello Everyone,

Howard W6HN:  I really do appreciate you and MFJ taking the time to bring a product like this to market.  I think it can really have some strong interest to new HAMs!  Unfortunately, the pricing just doesn't make much sense for a $35 computer.  Yes, I fully understand you won't have the volume nor margins to make boards as inexpensive as the Raspberry Pi manufacturers but a better match is required.

Few questions if I may:

   - What sound chip are you using on your board?

   - Is this sound chip natively supported by Linux or do you require a unique distribution on the SD card?

   - Is it connected via I2C or SPI?

   - I assume there is an isolated PTT circuit on this board too?

   - Is the GPIO pin used for PTT assignable or fixed?

   - Do the isolation transformers support wider bandwidth requirements for say 9600bps G3RUH FSK or 4800bps WB2OSZ PSK modes?  If no, can the transformers be easily bypassed?

   - Which 3.5mm connector on your board is in the middle one that's pushed back to give room for the display connector?  This is going to be a challenge to reach for people wanting to put this in a case.  Maybe a short extender adapter might be available to make all three connection physically even?

   - Any plans to offer RigPi boards that have a complete Raspberry Pi 40pin header (with extra long pins) so users can put on additional HAT boards on top?  Maybe with matching long standoffs too?


Maybe these questions and answers would be good to put on a FAQ on your website.
