Hello I want to modify the order in which messages are sent . After discovering neighbors , i want that the one who will send , send his messages by priority : the one who has more interest is sent the first . I didn't know where to do the modification ! The second problem is when i impoted the android project and run it, it tells me that the daemon is not installed . Can you help me ?

Static routes - configuration file
by Sandra Siby 03 Apr '14

03 Apr '14

Hello, I have 3 nodes A, B and C and I would like a route from A->B->C (A and C should not exchange data). I have tried to set up the static routes using previous answers in the forum but have been unable to do so. In the configuration file, I see these lines: #list pattern ^dtn://[[:alpha:]].moon.dtn/[[:alpha:]] #option destination dtn://host7 May I know how to edit these parameters to establish the routes? Thanks! Regards, Sandra

ibrdtn for broadcom architecture
by Francisco Cuesta 02 Apr '14

02 Apr '14

Hello IBR staff, I was wondering whether you have available a version of ibr dtn openwrt packages for broadcom 2708 chipset, it is based on arm architecture, quite similar to raspberri pi. I have seen here http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/download#OpenWRTrep… that you mention the possibility to find different architectures in your jetkins builder, however, I could find any reference to broadcom architecture there. Therefore, I tried to crosscompilie ibr dtn from source aiming to that architecture and with openwrt as OS. I got the daemon, libraries and binaries, but now I get the following error when trying to start the daemon itself. root@OpenWrt:~# dtnd dtnd: error while loading shared libraries: libm.so.0: cannot open shared object file: No such file or directory Did I miss to include some library when crosscompiling? Or I am missing it on my openwrt OS? In such a case, what libraries should I install? Thanks in advance, Regards! Below all the packages I installed listed with opgk list root@OpenWrt:/lib# opkg list base-files - 118.2-r39952 blkid - 2.21.2-1 block-mount - 0.2.0-9 busybox - 1.19.4-6 dnsmasq - 2.66-2 dropbear - 2011.54-2 e2fsprogs - 1.42.4-1 gdb - 6.8a-4 hotplug2 - 1.0-beta-4 hwclock - 2.21.2-1 iw - 3.6-1 jshn - 2013-10-19-734d28eb1a46358743cf8837c91e5d46695c3b91 kernel - 3.3.8-1-85fa4859c0083294a4ca10e855c97bf6 kmod-ath - 3.3.8+2014-01-23.1-1 kmod-ath9k-common - 3.3.8+2014-01-23.1-1 kmod-ath9k-htc - 3.3.8+2014-01-23.1-1 kmod-cfg80211 - 3.3.8+2014-01-23.1-1 kmod-crypto-aes - 3.3.8-1 kmod-crypto-arc4 - 3.3.8-1 kmod-crypto-core - 3.3.8-1 kmod-fs-vfat - 3.3.8-1 kmod-hid - 3.3.8-1 kmod-input-core - 3.3.8-1 kmod-input-evdev - 3.3.8-1 kmod-ipt-conntrack - 3.3.8-1 kmod-ipt-core - 3.3.8-1 kmod-ipt-nat - 3.3.8-1 kmod-ipt-nathelper - 3.3.8-1 kmod-lib-crc-ccitt - 3.3.8-1 kmod-mac80211 - 3.3.8+2014-01-23.1-1 kmod-nls-base - 3.3.8-1 kmod-nls-cp437 - 3.3.8-1 kmod-nls-iso8859-1 - 3.3.8-1 kmod-sound-arm-bcm2835 - 3.3.8-1 kmod-sound-core - 3.3.8-1 kmod-usb-core - 3.3.8-1 kmod-usb-hid - 3.3.8-1 libblkid - 2.21.2-1 libblobmsg-json - 2013-10-19-734d28eb1a46358743cf8837c91e5d46695c3b91 libbsd - 0.3.0-1 libc - 2.15-1 libcom_err - 1.42.4-1 libcurl - 7.29.0-1 libdaemon - 0.14-2 libext2fs - 1.42.4-1 libgcc - 4.6-linaro-1 libip4tc - 1.4.10-5 libjson - 0.11-2 libjson-c - 0.11-2 liblua - 5.1.4-8 libmount - 2.21.2-1 libncurses - 5.7-5 libncursesw - 5.7-5 libnl - 2.0-1 libnl-tiny - 0.1-3 libopenssl - 1.0.1e-1 libpthread - 2.15-1 libpthread - 0.9.33.2-1 libreadline - 5.2-2 librpc - 0.9.32-rc2-0a2179bbc0844928f2a0ec01dba93d9b5d6d41a7 librt - 2.15-1 librt - 0.9.33.2-1 libsqlite3 - 3071201-1 libstdcpp - 4.6-linaro-1 libubox - 2013-10-19-734d28eb1a46358743cf8837c91e5d46695c3b91 libubus - 2013-08-08-b20a8a01c7faea5bcc9d34d10dcf7736589021b8 libubus-lua - 2013-08-08-b20a8a01c7faea5bcc9d34d10dcf7736589021b8 libuci - 2013-06-11.1-1 libuci-lua - 2013-06-11.1-1 libuuid - 2.21.2-1 libxtables - 1.4.10-5 lua - 5.1.4-8 luac - 5.1.4-8 mount-utils - 2.21.2-1 netifd - 2013-07-16-2674941b06c1ec67f1aff1bff9212e1372106641 opkg - 9c97d5ecd795709c8584e972bfdf3aee3a5b846d-3 swap-utils - 2.21.2-1 terminfo - 5.7-5 ubus - 2013-08-08-b20a8a01c7faea5bcc9d34d10dcf7736589021b8 ubusd - 2013-08-08-b20a8a01c7faea5bcc9d34d10dcf7736589021b8 uci - 2013-06-11.1-1 zlib - 1.2.7-1

Hi, I have a question about dtnsend. IBR-DTN runs on four PCs called A, B, C and D. When I send the text file from A, I wish B, C and D receive the file. Can I use something like broadcast adress in destination of dtnsend?

A) I do not have idea what is the meaning of *ERROR IPNDAgent: join failed on wlan0; 99: setsockopt()*, someone faced the same problem? Any tip will be very appreciated. B) Note that I edited a configuration file and changed the URI, but even passing my configuration file with the -c, the local node name is always dtn://OpenWrt #here is the option edited in my config file option uri dtn://NewID Well, continuing: I started the daemon at the router with "dtnd -i wlan0" and received the same message as in (2) or (3). I also installed the IBR-DTN on my laptop and started it with: "dtnd -i wlan0 -v -c /etc/ibrdtn/ibrdtnd.conf" Even with the error message shown (*ERROR* *IPNDAgent*) I am able to send files using the dtnsend and dtndrecv application in both directions (from the laptop to the router and from the router to the laptop), however, the dtnping application did not worked. In a nutshell I'm having 3 problems: 1 - the IPNDAgent error (openwrt router). 2 - the configuration file error (openwrt router) 3 - the ping application Thank you in advance.

Did you try `ibrdtn stop` or `service ibrdtn stop` (maybe it should be ibrdtnd, not ibrdtn; not sure at the moment). Did you install the .deb-files? Then it should work with service. You also can kill the process using `killall -KILL dtnd`. And again, please reply to the list ;) Stephan
