[PATCH] chan_usbradio fixes for newer kernels
by James Le Cuirot 18 Dec '11

18 Dec '11

Hello all, As mentioned in my previous post, I needed to make changes to chan_usbradio as well as Zaptel for Linux 3.1.0. The crux of the issue here was that the structure of /sys had changed. The first clue was when Asterisk started reporting that the USB device ".." had been assigned to a radio channel. The code previously looked up a path like: /sys/class/sound/dsp1/device On older kernels, this path would be a symlink to something like: ../../../devices/pci0000:00/0000:00:04.2/usb1/1-1/1-1:1.0 The second last component of this was extracted, resulting in 1-1. However, the above symlink now simply points to ../../card1, resulting in .. as I mentioned before. Now everything under /sys/class/sound is also a symlink and it is these that need to be queried instead. For dsp1, the new target is: ../../devices/pci0000:00/0000:00:04.2/usb1/1-1/1-1:1.0/sound/card1/dsp1 This is similar to before but the code that previously handled the path extraction was long winded. basename and dirname do the job for us much more efficiently. This new code will not work on older kernels. I was going to address that issue when it occurred to me that this whole process is very convoluted and over-complicated. Surely libusb can simply tell us the "devstr" value without having to iterate over all the sound cards and then go digging around in /sys? As it turns out, it can't, at least not in this version. The old "legacy" libusb API is being used here. The newer API includes a function called libusb_get_device_address but I'm not sure whether this returns the right information. The following discussion from August has led me to believe that the function we need may actually be introduced in the next version. http://libusb.6.n5.nabble.com/Find-specific-USB-device-based-on-udev-info-t… Despite this, I was still able to simplify the confusingly named usb_get_usbdev function. Instead of iterating over all the sound cards, looking for the one that matches the given devstr, we simply look up the device directly under /sys. For the 1-1 example: /sys/bus/usb/devices/1-1/1-1:1.0/sound This is a directory containing just one other directory, card1 in this case. We just look for a directory starting with "card" and take the number from the end. Job done. So to sum up, the attached patch works but only with newer kernels. I don't know exactly which kernel version introduced the change. It may have been as far back as 2.6.25. This could be fixed up to work with older kernels too but moving to the newer libusb and vastly simplifying this code is well worth considering. Of course, so is ditching Asterisk, but that's covered in my other post. ;) This code would look much the same under any system anyway. Regards, James

Allstar Link Support
by Marshall Oldham 18 Dec '11

18 Dec '11

Greetings fellow Allstar link members, I am writing this email with the hopes that we as the amateur community can step forward and support our hobby, mainly the app_rpt and allstarlink technology that we all enjoy today. As many of you might NOT know, the creator of app_rpt and the allstarlink network has never charged or asked for financial support to keep the allstarlink system going. He has never charged users money to be a part of the allstarlink network, nor has he ever made any profit off of specific hardware sales for the allstarlink network. Through the years he has put in a great deal of time and dedication along with his exceptional talents to make app_rpt and the allstarlink network the great VOIP technology that it has become today. No other VOIP technology in the amateur radio community can even compare to the technology, features and capability that is offered for free to anyone wishing to setup there own allstarlink node. Another unknown fact is that there are monthly costs associated with keeping things running smoothly for the allstarlink system. These costs are for server collocation, domain certifications and so on, amounting to roughly $175 per month. Jim has been paying these monthly fees out of his own pocket. Wouldn't it be nice if we could all pitch in and help him to at the least cover these monthly costs for this coming year? I am proposing that we all donate to this cause via PayPal at the following URL. https://allstarlink.org/ At the top of this webpage just slightly down there is a PayPal donate button. In the spirit and season of giving, lets all do our part to try and help out with the financial side, so we can continue to use and enjoy this great technology that we have all come to know and love! I would also like to say thanks to Jim, WB6NIL for all the many hours of work and support that he and others have donated to this hobby so that the amateur community at large can benefit and enjoy the use of this technology on a daily basis for free. 73 Marshall - ke6pcv Node 2065, 2066

Can't compile latest svn
by Buddy Brannan 17 Dec '11

17 Dec '11

Hi, I'm not sure what has changed (or what I should change), but for some reason, the latest asterisk from svn won't compile. This started a couple weeks ago, and I accidentally *really* broke things. Fortunately I had an old source tree and have a now working 0.281. Even grabbing a fresh download, rather than updating what's already there, nets the same exiting of the make.

Courtesy Tone
by Matt Roberts 17 Dec '11

17 Dec '11

I am trying to set up a courtesy tone when I'm connected to another node. My remote courtesy tone is working fine. I can't figure out how to have a tone to sound when a user on my repeater unkeys. When my repeater is linked, I want a "K" to be heard when a local user unkeys on my system. When a remote user unkeys, you hear a double dial tone, adn I have CT1 set if my repeater isn't linked to anyone. Does anyone know what I need to do? I'm also discovering when I'm connected on my remote base, I get inactivity timeout messages. How do I disable them?

Re: [App_rpt-users] Low Band Remote Base
by Monty 17 Dec '11

17 Dec '11

Been working off list with David on this issue. Tried the manual split in the memory channel: *06 = 53.720,136.5,1000,h-t *Still will only do a 0.5 mhz split, even tried 2000 just to make sure. In Checking the source, it looks like that only applies to Kenwood radios in 2m/70cm. My question is could this capability be added to accommodate the low band Syntors with the Xcat?

Echolink whitelist limitation
by GARY BONEBRAKE 16 Dec '11

16 Dec '11

I added the "permit=" statement at the end of echolink.conf to limit access to club members only. I did this to eliminate the plague of ungracious and irresponsible skimmers, dropins and lurkers. Refer to http://ohnosec.org/drupal/node/56 for details. However, I discovered that there is a limit on the number of entries in the "permit=" statement. If you add more than 30 calls, the system will disconnect after about 10 seconds and respond with an RTCP TIMEOUT . Multiple "permit=" statements do not work - only the first statement is acknowledged. [The limitation is in line 154 of chan_echolink.c - "#define EL_MAX_CALL_LIST 30"] If you know of an alternate method to create a lengthy whitelist for Echolink in app_rpt, please advise.

Best of luck. Is it possible to use DTMF to control your node if connected via SIP softphone? That might be a neat capability to have. 73. Kyle K0KN
