That means, though you use a really very, very old version of californium (I even don't know, where you got it from), it doesn't longer work!

Either just download the current 2.0.x or 1.0.x either with git or just with your browser. Select the < > Code tab next to the Issues tab. Select there in the "Branch" selectbox (left) either 2.0.x or 1.0.x. After selecting the wanted "Branch", select the "Clone or Download" on the right.

If you get one of these current versions, try to build it again.

i use 1.5-snapshot the problem is here: [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] Source option 5 is no longer supported.

[boaks]

Sorry, either download, what I recommend (and that is not a version 1.5-SNAPSHOT, I even don't know that version), or ask those, where you have downloaded your versions, for support.

Also, if you wan't to fix it on your own, try a internet search with the error description. You will easiliy find explanations and how to fix it.

But I will only be able to help you for 2.0.0-M12 or 2.0.x-SNAPSHOT and, if you give me a good reason why you required to use the 1.0.7-SNAPSHOT, also for that.

[jabberimaher]

i'm sorry i can not add demo-apps / sc-dtls-example-server as server and demo-apps / sc-dtls-example-client as client. I don't know if I add them by modifying only the pom.xml file or there are other steps, I installed californium 2.0.0.M12 then I have the following parent tree / src / org / eclipse / californium / app.java. ... I need the pom.xml file needed for adding californium and demo-apps and the other steps if they exist. thank you

[boaks]

Californium 2.0.0-M12 already contains the demo-apps! You don't need to add them. At the end of the log from your maven build, there should be a Reactor Summary, which contains all the build module.

Do you get a similar summary? If so, https://github.com/eclipse/californium/issues/787#issuecomment-449651404 should contain the instructions to execute the examples.

If it builds, you may use demo-apps/sc-dtls-example-server as server and demo-apps/sc-dtls-example-client as client. To do so, open a terminal in the californium/demo-apps/run folder and execute java -jar sc-dtls-example-server-2.0.0-SNAPSHOT.jar and afterwards from an other terminal in that folder java -jar sc-dtls-example-client-2.0.0-SNAPSHOT.jar. The client should the print

Create 1 DTLS example clients, expect to send 100 messages overall. 1 DTLS example clients started. 1 DTLS example clients finished. 100 messages received, 100 expected 100 messages in 338 ms 295 messages per s

Or something similar.

how i realize this work and can i implement others authentication algorithms?

This depends of the scope of your "authentication algorithms" and your work.

If your intention is to "authenticate" the other peer, californium offers ciphersuites with PSK (PreSharedKey), Raw Public Key, x509v3 Certificate based ciphersuites.

TLS_PSK_WITH_AES_128_CBC_SHA256 TLS_ECDHE_PSK_WITH_AES_128_CBC_SHA256 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 TLS_PSK_WITH_AES_128_CCM_8 TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8

So, if you want to compare them, you may use demo-apps/cf-secure project. Also open two terminals in californium/demo-apps/run and start the server with

java -jar cf-secure-2.0.0-SNAPSHOT.jar

and the client with

java -cp cf-secure-2.0.0-SNAPSHOT.jar org.eclipse.californium.examples.SecureClient PSK

At the end of the console output, there should be something as:

==[ CoAP Response ]============================================
MID    : 27727
Token  : 746DFCEF9FACAC46
Type   : ACK
Status : 2.05
Options: {"Content-Format":"text/plain"}
RTT    : 129 ms
Payload: 14 Bytes
---------------------------------------------------------------
hello security
===============================================================

You may replace PSK with RPK or X590.

If you want to compare with other ciphersuites, e.g. some with MD5, I would recommend to use some TLS (openssl) libraries, which offers that. To extend californium with old MD5 is not planned at all and will be extremely hard to do.

I' still not understand, why you want to use java to measure the energy consumption.

So: do you have a "demo-apps" folder? Does it contain a "run" folder? Are the three jars mention above in your reactor summary and in the "run" folder? Are you able to open a command terminal in that folder (alternatively change the cd of your command terminal to the "demo-apps/run" folder)?

[boaks]

No glue, what your doing! Seems to be totally mixed up!

Did you download californium? If yes, which link did you use? Or did you clone the repo? If yes, which link did you use as remote-repository?

If you open the web-page https://github.com/eclipse/californium you see the instructions to build californium (https://github.com/eclipse/californium#build-using-maven). I don't know, why you use mvn archetype:generate -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.1.

So:

• download or clone californium
• open a command-terminal in the californium parent folder
• build it as documented under the link above.

Doing so should print after some lines Building Californium (Cf) Parent 2.0.0-SNAPSHOT and NOT 2.0-sNAPSHOT.

I still wait on the answers to my questions :-)

question :why you want to use java to measure the energy consumption.?????:-) professor , i need to compare between dtls handshake and MDA, then i need a simulator who performs this task i tried contiki, but after three months i did nothing. I was advised to use another one and this is californium. ..................................... i think there is problem when running example dtls client, almost 3 hours of execution of the order and it does not show anything, I think it is blocked..no?.

The link was to my comment above, the questions are:

Did you download californium? If yes, which link did you use? Or did you clone the repo? If yes, which link did you use as remote-repository?

That's important to know, what you did, because, you obvious using the wrong stuff (1.1.0 instead of the recommended 2.0.0).

i think there is problem when running example dtls client, almost 3 hours of execution of the order and it does not show anything, I think it is blocked..no?.

Sure, there is a problem running a DIFFERENT VERSION of the examples than recommended! In your case, the server accidentally terminated (caused by a missing fix, which is already applied to 2.0.x), therefore the client fails also.

But again, if you do things different, don't complain, if it's not working.

So answer the two questions above, then I know, what you have and how to help you, to get the right stuff.

link download californium: https://github.com/eclipse/californium#build-using-maven

[boaks]

That's the link, obvious to the section "build using maven". You can't download the source package nor the git repo with "exactly that link". And you even didn't answer, if you have downloaded californium or cloned the git repo. So did you download something with your browser? Or did you clone something with "git clone ..."? One should be yes, and then provide the used link, not a link to somewhere ...

[jabberimaher]

i downloaded californium with browser, i didn't clone it

7 days ago, I wrote in my first answer here in this issue

Either just download the current 2.0.x or 1.0.x either with git or just with your browser. Select the < > Code tab next to the Issues tab. Select there in the "Branch" selectbox (left) either 2.0.x or 1.0.x. After selecting the wanted "Branch", select the "Clone or Download" on the right.

I guess, you didn't follow

Select there in the "Branch" selectbox (left) either 2.0.x or 1.0.x.

So follow it, select the 2.0.x branch and you will get a more current version. Good luck :-).

[boaks]

If you select the right branch 2.0.x, the download link is

https://github.com/eclipse/californium/archive/2.0.x.zip

hello professor, I apologize for the long break, but I was sick and I can not move my legs. i download californium from the recommended link and using the described steps but at the end of installation it displays this error: [ERROR] /home/maher/californium/californium-core/src/main/java/org/eclipse/californium/core/network/config/NetworkConfig.java:406: Undefined reference: void AutoCloseable.close() [ERROR] /home/maher/californium/californium-core/src/main/java/org/eclipse/californium/core/network/config/NetworkConfig.java:406: Undefined reference: void Throwable.addSuppressed(Throwable) [ERROR] /home/maher/californium/californium-core/src/main/java/org/eclipse/californium/core/network/config/NetworkConfig.java:406: Undefined reference: void AutoCloseable.close() [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] Californium (Cf) Parent ............................

Do you use Java 1.6?

Check may be done with java -version of javac -version.

[boaks]

If you use java 1.6, please try to update at least to 1.7.
(May be it's easier to update to 1.8.)

[boaks]

If possible for you, I would like to cleanup the issue #787 from this "build discussion". Would this be OK for you, if I delete your and my comments there?

[jabberimaher]

ok yes you can delete from 787

[boaks]

Seems you use different version for the compiler (javac 1.8) and runtime (java 10.0). If possible, please use also the 1.8 for the runtime.

Sometimes this is caused by using different "jdk" and "jre". To check that, use

sudo apt list --installed openjdk*

If that reports different versions, please uninstall the openjdk-10-jre (or what ever version is reported for the jre) and install openjdk-8-jre.

[boaks]

OK, now jdk and jre are both 1.8. Great!

root@maher-Lenovo-G50-80:/home/maher/californium# mvn clean install The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE

That are general java and maven installation issues. Please use a internet search machine to solve it. Java installation is sure no californium specific issue.

[jabberimaher]

thanks a lot professor, i resolve the problem by adding to /etc/environment the line: export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64. i try dtls server/client and cf-secure, it's ok.

now if i want to create scenario wsn : a node sensor would to authenticate with a cloud server and i measure the consumption energy of the sensor and the needed time of authentication. i need to create new isuue??

[boaks]

i try dtls server/client and cf-secure, it's ok.

Congratulation!

now if i want to create scenario wsn : a node sensor would to authenticate with a cloud server and i measure the consumption energy of the sensor and the needed time of authentication. i need to create new isuue??

I'm not sure, what you expect as help. If you can execute the cf-secure demo, why are you not able to do these measurements? "Time" should be easy and "energy" depends more on your client. So both seems to be not really related to californium. But sure, if you want, you may open a new issue and ask other californium users to share their experience with you. I'm not sure, if someone has already that special experience.

[boaks]

If it builds now, can we close this issue?

[jabberimaher]

ok thank you
