The hashes generated on the Raspberry PI are different from other systems.
This is probably a bug related to Endianness.

I compiled and started kadnode in raspberry pi and it gives me this. I think it has something to do with ipv6 but dont know how to fix it.

I just installed the newest version of kadnode in raspbian and I get this error on any connection to the internet. Ping ,wget , git clone dont work and give this error...

symbol lookup error: /lib/libnss_kadnode.so.2: undefined symbol: addr_parse

can you give of a working kadnode without the libsodium dependency. I havent used the authentication feature in my diploma so Its more trouble for now.
I tried to checkout to a previous version but I dont really know how to do it.
can you give me a link to a tar file?

How i can build it on OS X?

UPNP would allow KadNode to instruct a Router to do port forwarding for the DHT.
But it would also allow to automatically open ports for id/port pairs identifiers
that are announced by the KadNode instance.

Fo example, if KadeNode on a computer behind a router announces abcde:80, KadNode could tell the router to forward the external port 80 (of the router) to the local port 80.

Transmission uses a Local Peer Discovery (LPD).
Kadnode uses an own multicast ping mechanism.
If possible, it is preferable to use the Transmission LPD implementation.

I want to implement couchdb replication feature over dht using kadnode.
Couchdb is a json-oriented database that allows replication between two nodes through http.I am trying to use kadnode as a way for couchdb instances to find each other. I am using python to access and control the couchdb. Could you give me some guidelines or ideas on how to make the couchdb and kadnode cooperate.
Thanks for your support

I was able to test your code today because I was busy.There seems to be a problem with libsodium.I installed libsodium from here http://download.dnscrypt.org/libsodium/releases/
I git cloned KadNode ,make ,sudo make install.
when I run kadnode I get this:

kadnode: error while loading shared libraries: libsodium.so.4: cannot open shared object file: No such file or directory

I want to test your authentication feature...

Probably a fairly minor issue, but it appears that libsodium13 and libminiupnpc5 are both gone in the latest Linux Mint repository, but the program will install, run, and connect if I change the Debian control file to reference libsodium18 and libminiupnpc10 instead, but I'm not sure what the actual difference between the packages is so it might not "actually" be working.

If the packages really are mostly the same, it would be fairly simple to fix, but I'm not sure what the difference between them actually is.

This looks like it could be great for IoT applications, home automation and chat programs if it ever really went mainstream.

Hi,
I am trying to use kadnode but I cant understand how to join an existing swarm?
I tried "import {ip}" where ip was found from a swarm of a torrent file nothing changed.

How difficult would it be to issue a domain with kadnode and authenticate it using the mozilla persona?
Some info https://developer.mozilla.org/en-US/Persona/Crypto
https://github.com/mozilla/jwcrypto

i will try config via postinstallmeshscript:

http://trac.augsburg.freifunk.net/changeset/895

@mwarning can you please give me an example of announcing and searching a value on runtime with kadnode-ctl.
I want to be able to do something like this:

On node 1:

kadnode-ctl announce nodename.p2p:<secret_key>

On node 2:

kadnode-ctl search nodename.p2p:<public_key>

I really need this for my software.I wonder if you could add this feature.I have already asked the same question but was waiting for an example.

There is a problem in Windows
first DNS server points to Google(8.8.8.8)
second DNS server - Kadnode service(127.0.0.1)

nslookup myserver.p2p

google cant'resolve this address.
then nslookup stops.

if we setup first DNS Kadnode (127.0.0.1) - only our .p2p hosts resolvable
other internet - NO.

I think some getHostbyName() code needed to resolve addresses from Internet DNS servers.

Hello mwarning,

/mylife/
First of all thank you to have make it !

This said, i m very interested in re implementing part of your software in nodejs.
Partly because i don't understand very well C and i can t write it.
Also because i have good platform to make this kind of software fit in (ie maboiteaspam/cozy-light).
More surely because DHT and DNS implementation both are existing right now in NodeJS.
Thus, i think i probably only have to realize the job to glue everything all together to make it workable.
/mylife/

Here are some questions i m trying to solve, but maybe you have time and wheeling to help me to answer.

• Reading the source code i have not yet clearly understand the content of the announce made on the DHT.
  Particularly it s about those part

int dns_lookup_addr( const char hostname[], IP addr[], size_t addr_num ) {
    /* Start lookup for one address */
    if( kad_lookup_value( hostname, addr, &addr_num ) >= 0 && addr_num > 0 ) {
        return addr_num;
    } else {
        return 0;
    }
}

Then after this part totally loose me (...).
kad.c : kad_lookup_value
https://github.com/mwarning/KadNode/blob/master/src/kad.c#L427

• Are you using a modified version of DHT implementation ?
  I ask because i saw you have embed dht.c, not sure the reason.
• How have you proceed to test your software ? Is there existing nodes i can use during my development to test it on a real landscape ?

Again, thank you very much for this work !

It is easier for many purposes to just use the lookup command.
If a search has not yet been performed then just start one.

Two issues and how to resolve them:

I was following your build instructions.

I resolved the issue with the undefined references by using makepkg LFLAGS+=-lsodium instead.
Now the build was successful.

Another issue arose when I installed the package.
kadnode: /lib exists in filesystem
This is due to a change in how pacman handles symlinks
I just had to change:
install -Dm644 build/libnss_kadnode.so.2 "$pkgdir"/lib/libnss_kadnode.so.2
to
install -Dm644 build/libnss_kadnode.so.2 "$pkgdir"/usr/lib/libnss_kadnode.so.2
in PKGBUILD.

I have a dnsmasq startup error with
uci add_list dhcp.@dnsmasq[0].server='/p2p/localhost#5353'
bad address at line 12 of /var/etc/dnsmasq.conf
line 12
server=/p2p/localhost#3535
I have replace the hostname with ip addr. Then this works fine.
uci add_list dhcp.@dnsmasq[0].server='/p2p/::1#5353'

Is it difficult to add python bindings to kadnode-ctl so I can work on my project easier.
If its too much I am asking no problem.I'll find a way.I tried to do it myself with this https://github.com/orangeduck/PyAutoC but cant make it compile.My knowledge of C coding is really small..

Hi,

I've been looking a bit into your software for the last couple of days and I wanted to build a quick "benchmark" program in golang to evaluate what latency we can expect. To do so I announced a several node names with --value id (500 to be precise) on a node, an tried to resolve them on another machine.

The thing is that after 60~ successful lookups on the client trying to resolve these, Kadnode only throws "Some error occured.", either directly through Kadnode's console or via Kadnode-ctl.

The benchmark I do in go is pretty much straight forward, I mimic Kadnode-ctl by sending UDP messages to the running instance of Kadnode, throwing "lookup Xmynode.p2p" every 100ms to Kadnode and when Kadnode replies with an IP adress, I register the time it took to look it up.

Any idea where this might come from ?

Currently, announcements (--value-id) are send at startup even if KadNode has itself not properly bootstrapped into the network.

Solution - wait a few seconds after startup for the first announcement to be made.

the config in /etc/config/kadnode changed from ifce to ifname? daemon doesnt start :-(

root@234-8:# vi /etc/config/kadnode
root@234-8:# /etc/init.d/kadnode restart
(E) CFG: Unknown command line argument: '--ifname'

I wrote a python script that communicates with an online couchdb database which works as a certificate authority. ( https://gist.github.com/vkefallinos/58936be087ad3b7bb280 )
When I lookup a domain with encryption it keeps searching forever.
The script works with three commands
"python kadnode.py announce domain"
or 'lookup domain'
or 'status'.
You need to install python-couchdb with "pip install couchdb".
On node1 run : python kadnode.py announce node1
On node2 run :
python kadnode.py announce node2
python kadnode.py lookup node1

Every interaction with kadnode is printed on the console. Can you please check it?

Need to exchange public keys? How do you imagine that?

is there a way of configuring the buffer size for the dns records?
I am considering running kadnode as a dns cache on freifunk nodes and having one program to do dns instead of two (dnsmasq and kadnode) would be better.

The dns Port is only listen on legacy ipv4 socket

dig AAAA -p 3535 jabbahood.p2p @::1 ends up with time out.
the sendto() in https://github.com/mwarning/KadNode/blob/master/src/ext-dns.c#L622 return "invalid argument" because of wrong IP addr len.
Patch: stargieg@f0f7ea7

DSS/NSS can only transmit one IP address. But KadNode may receive multiple
IP addresses and will select just the first.
Therefore there is a way needed to filter those addresses. This could be done by means of a script etc. that is called in between.

I managed to install kadnode0.4 on a raspberry running raspbian and after running it the same id produced different hash from my laptop(installed it two weeks ago).
laptop:kadnode-ctl announce vkefallinos
Announced resource: 5ba1e8ef7588bd30c3a141e5de8afcd00d72642b
raspberry:kadnode-ctl announce vkefallinos
Announce resource 81f95a017f8cc3eb13abcd1683ac5a7e1b71e9df on port 1 for 30 minutes.

So I figured I should the same version on both computers.
So now I cant even install it.
when I try to dpkg-buildpackage in linux mint the package libminiupnpc-dev was needed and after installing that it says

is kadnode for windows in plans?

Is there a way for kadnode to ask a question to another node that it found and receive an answer? I want this so I can verify that the node I found is actually the node I wanted.

support Interface list in ifname config option.
e.g. Listen on lan and wifi but not on wan.

My program announces a value, does lookup for 1 minute and after that it announces 3 values. The first of the 3 values is announced. The other two give no response received. I give 15 seconds between every announcement. Does it need more time?
Also when i run "pidof kadnode" it gives me multiple pids.

I have two kadnode instances running with a custom tld called ".ffffm"
the value-ids are tcs1.ffffm and tcs2.ffffm. using
kadnode-ctl lookup tcs1.ffffm or kadnode-ctl lookup tcs2.ffffm I will receive a reply with an IP-Address however running a wildcard lookup like
kadnode-ctl lookup "*.ffffm" I am not receiving a result but seeing "Search in progress" for minutes already.

What should I do to investigate?

Despite my claims, this stil seem not to work properly. Pakets are send, but not received when they not from the local system.. investigating.

Hi

I was wondering instead of sending back an IP as a result of a DNS request, can it send back a transaction number from bitcoin blockchain?

Or maybe with a few mods to this codebase, can we change it to do so?

The current version fails (on some hosts) because stdio.h is missing in src/ext-cmd.c

I am starting kadnode in the university network with a public ip which has all the ports open and no upnp on nat enabled.When I kadnode-ctl it gives me no response received. I think kadnode has a problem when it has a public ip.Can you please help me.

I can't understand how to configure:

first node config:
--peerfile /etc/kadnode/peers.txt
--value-id s17.p2p
--auth-add-skey s17.p2p:c84995c206b6fd702d9af43497faa4fb10e3e847fe068350a5fdc851d84ed72690d59cdde52e2d858746efd4c0e5f14ad8c5d80b7f6b879cbcd4ed45142ffa4b

What is wrong?

Hello once again..
Is it possible to announce a node with auth after kadnode has started?
--auth-add-skey and --auth-add-pkey is only available through kadnode.
Announce with secret key and lookup with public key is not available or I haven't found how to implement it.

I found in Your code that kad_lookup value is updated after 10 minutes.
kad.c
if( results_entries_count( results ) == 0 || (time_now_sec() - results->start_time) > (MAX_SEARCH_LIFETIME / 2) ) {
Good Idea!

But in results.c
void results_expire( void ) { if( results->start_time < (now - MAX_SEARCH_LIFETIME) ) { results_remove( results );

You remove search results after 20 minutes.
And a new search request, on demand takes some time.
It is not comfortable for desktop use, for example in browser.

Maybe to do remove_results_time 1 day or even 3 days?
