The PiCam has sucked up my free time since the idea of a hidden Racoon Camera came to mind, something to see what eats my garden late nights so I can give advice that. Thanks in advance ..... Bill k6acj |

Re: Question of telnet
Good advice from the previous two posters, telnet was designed in the 60s (70s?) for use in closed networks and doesn't have the security needed in today's world.
I don't know if you've checked, but the Arch Linux wiki is one of the best (if not the best) sources of advice around for all distros (although you may need to check out alternative file names if you're using another distro). I don't know if it's been mentioned here but the Linux Foundation is running a course at , (edx.org)it's free (unless you want a validated certificate) and has no start/end dates so you can join when you like & progress at your own pace.

Hi Jason,

Linux systems will generally have the telnet server disabled (or even not installed) by default. The reason is your session is sent unencrypted over the wire; not good for security. All distributions will have SSH (secure shell) server enabled by default which will provide "telnet like" access to your Pi but with the session encrypted. On the client side, Linux comes with an ssh client so you don't need to install anything. On Widnows, you'll need to install something like putty. A repository allows you to install other programs; no need to transfer any files. The only reason you would need to create a local repository is when your device is not connected to the internet, or you have that many devices on your network you don't want them all accessing the same thing over your internet connection. For a simple home connection, I'd leave the repo configuration as is and rely on the community servers. This saves you the headache of keeping your repo in sync with the upstream servers. If you are only transferring files, then I would suggest sftp (secure file transfer protocol) which uses the SSH server already installed. Linux distros have a client by default; not sure about the others. If you want a GUI, I prefer the FireFTP plugin for Firefox. Ian VK1IAN On 07/09/14 07:30, aj26scm@...

Question of telnet
Hello, All;
?Im currently working on a bbs project on one of my pi's. Once I get it running and figures it out I want to try hooking into my broadband hamnet routers I have set-up. ?I have managed to get my way thru installing and setting up arch linux, and then got mystic bbs dwnld and some what configured. To pat myself on the back with alot of hair pulling and not outside help cause Im still learning linux. Now Im alittle confused on telnet stuff, Do I just need to download telnet client or find telnet server? In everything I have found on my search most people suggest telnetd, but some say server other say client. Next question is can some one point me to possible a article or show me a example of adding a repoistory for pacman to search for files. Im currently downloading files to usb stick on my laptop and transfering them over to pi. I have read the txt file on my pi about setting up a repoistory and Im apparently not understanding something cause I have had no luck and even crash my arch once already. Learn all this slowly and surely, Jason Hopkins KF4PMY |

It's working now.? It takes 2minutes 7
seconds from taking the picture to finishing transmission.? I
still have to fiddle with the timing to straighten the picture out
but that's not a big deal.

Re: New file uploaded to Raspberry_Pi_4-Ham_RADIO
Dear friends,
attached is the updated version of the bash script to make a beacon / telemetry station / autofox. Now it is possible to adapt it (the mods are very easy to apply) to be: - an audio voice and/or packet radio beacon (through the Pi audio output jack), or - a FM Radio Transmitter for voice and/or packet radio beacon (through the usual GPIO pin). If all of the options are enabled, the script makes use of Festival as vocal synthesizer and Alsa as audio manager; so they must be installed properly if they're used. One of the upgrades concerns the adoption of a ramdisk to avoid the risk of damaging the SD card because of too many writing operations. The activation of a signal/alarm input from a GPIO pin was also added as for example or suggestion for further implementations. Another GPIO is set as an output port; this is useful, for example, to light on a led indicating RF output or to switch amplifiers, filters, the PTT of an external Radio and so on. Now the program "says" the Core temperature, the CPU load and internal clock Time. It gives also an alarm message if the level of the, internally pulled-up, GPIO 22 goes low. All the data are also stored in the file /mnt/ramdisk/Logger.txt Please take care it is a temporary saving because it's a ramdisk. Run ./TX-CPUTemp.sh for help and instructions. Have fun! 73s de IK1PLD |

Re: Has anyone used a Raspberry Pi to run Slow Scan Television
Hi Mathison.? I've been playing around with
Thanks to David's help, I have captured an image with the picam, transmitted it over 2m and captured it with mmsstv. There's still a ways to go before I'm ready to put it on the air but the test run so far looks good. |

Re: New file uploaded to Raspberry_Pi_4-Ham_RADIO
Dear friends,
attached is the modified packets generator (derived from the great DireWolf by WB2OSZ). The compiled version is ready for Raspbian. This utility "pkt2wave" is useful to generate wav files containing unproto packets for testing, telemetry, APRS, Cluster purposes, etc. The so created wav files can be supplied to the narrow band transmitter "./nbfm" to be able to operate packet radio without needing a TNC nor a Radio. Please run ./pkt2wave for help and instructions. Have fun! 73s de IK1PLD |

When I enterThis is a message from ld, the linker that forms part of the gcc compilation chain. It's complaining that it can't find the symbol "sin". I assume this is the mathematical sine function. The usual reason for this sort of error is that you haven't explicitly asked for the maths library to be linked in. It may seem odd, but C compilers don't usually include the maths library by default, even if the source code contains "#include <math.h>"! Try adding -lm to the command line options and see if that cures the problem: gcc -lm -lgd -lmagic -o pisstv pisstv.c David |
