Hey, my Asterisk got a problem with the chan_dect module. I build it like it's written here: http://dect.osmocom.org/trac/dect/wiki/Build%20instructions debian*CLI> module load chan_dect Unable to load module chan_dect Command 'module load chan_dect' failed.

Could someone help me, getting this fixed? -- -- Mit freundlichen Grüßen Henrik Hansen

debt 6.0 rf band

Hello, I am trying to use a dosh&amand PCI card… this one: 01:03.0 Communication controller: Quicklogic Corporation COM-ON-AIR Dosch&Amand DECT (rev 32) Subsystem: Device 1786:0001 Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 20 Region 0: Memory at ddefe000 (32-bit, non-prefetchable) [size=8K] Kernel driver in use: com_on_air_pci with the dect kernel stack… I have managed to compile the kernel 3.2.0 with this config: CONFIG_DECT=m CONFIG_DECT_DEBUG=y CONFIG_DECT_CSF=m CONFIG_DECT_RAW=m CONFIG_DECT_CCF=m CONFIG_DECT_LU1_SAP=m CONFIG_DECTDEVICES=y CONFIG_DECT_VTRX=m CONFIG_DECT_COA_PCI=m CONFIG_DECT_COA=m CONFIG_DECT_COA_U2785=y CONFIG_DECT_COA_FIRMWARE=y CONFIG_DECT_COA_P64=y The driver seems to work but the issue is that I am trying to use it in USA for an American client, and I did not managed to make this card use the 1.9Mhz band (rf band 3 I guess). When I run this command: dect-transceiver-list --name trx2 I see that slot0 is scanning: DECT Transceiver trx2@cell0: Type: sc1442x Features: slow-hopping,p64 RF-band: 00003 Events: busy: 0 late: 0 slot 0: <scanning> packet: P00 carrier: 5 (1888.704 MHz) RX: bytes 0 packets 0 a-crc-errors 1629 x-crc-errors 0 z-crc-errors 0 but it nevers uses RF band 3 channel.

Hi, I do not know how to build Wireshark-1.6.7 against patched libpcap. The Kernel 3.2.0+ is built and installed in directory: umberto@umberto-desktop:/usr/src The patched libpcap + libnl +libdect are built and installed in directory: umberto@umberto-desktop:/usr/src/tools Also the source directory wireshark-1.6.7 is in directory: umberto@umberto-desktop:/usr/src/tools I do: cd wireshark-1.6.7$ sudo ./configure --with-pcap=/usr/local/lib and I get the error: ........ checking for connect... yes checking whether to use libpcap for packet capture... yes checking pcap.h usability... yes checking pcap.h presence... yes checking for pcap.h... yes checking for pcap_open_live in -lpcap... no checking for pcap_open_live in -lpcap with -lcfg -lodm... no checking for pcap_open_live in -lpcap with -lpfring... no configure: error: Can't link with library libpcap. andrea@andrea-desktop:/usr/src/tools/wireshark-1.6.7$ What should I do?

Protocol mismatch error

Hello Patrick, I am currently working on my master thesis in computer science in which I'm trying to exploit you great open source software linux DECT-Stack. I plan to use it for controlling a Com-On-Air PCI ISDN card (Dosch&Amand). However, I'm facing problems with operating libdect, dectmon. To be more precise, after installing software and trying to run it I always get the following error message: dect_netlink_init: Protocol mismatch dect_init: Bad file descriptor root@dect:~/dectmon# valgrind src/dectmon ==4479== Memcheck, a memory error detector ==4479== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al. ==4479== Using Valgrind-3.6.1-Debian and LibVEX; rerun with -h for copyright info ==4479== Command: src/dectmon ==4479== dectmon > ==4479== Warning: invalid file descriptor -1 in syscall close() dect_netlink_init: Protocol mismatch dectmon > dect_open_handle: Bad file descriptor ==4479== ==4479== HEAP SUMMARY: ==4479== in use at exit: 65,329 bytes in 189 blocks ==4479== total heap usage: 305 allocs, 116 frees, 74,326 bytes allocated ==4479== ==4479== LEAK SUMMARY: ==4479== definitely lost: 0 bytes in 0 blocks ==4479== indirectly lost: 0 bytes in 0 blocks ==4479== possibly lost: 0 bytes in 0 blocks ==4479== still reachable: 65,329 bytes in 189 blocks ==4479== suppressed: 0 bytes in 0 blocks ==4479== Rerun with --leak-check=full to see details of leaked memory ==4479== ==4479== For counts of detected and suppressed errors, rerun with: -v ==4479== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 39 from 6) root@dect:~/dectmon# and for any dect-command in asterisk: No such command 'dect show portables' Since my master degree depends highly on successful usage of your software I want to ask you for help and would very appreciate it. It would be very nice if you could give me an advise on how the problem can be solved. Please let me know if you need additional info, esp. in case the error text is not enough for you to be able to analyze the error. Thank you in advance! Best Regards, Tasha
