keytool error with fvconfig generate config.xml

[09bicsemalam]

Hi.

I was following the installation instruction in the flowvisor installation manual [1]. But when it comes to generating config.xml through fvconfig, it gives me the following error:

fvconfig generate /usr/local/etc/flowvisor/config.xml

Could not find /usr/local/etc/flowvisor/envs.sh: dying...

I ensured the folder is accessible but again on running the above command, I got:

netforall@netforall:~$ fvconfig generate /usr/local/etc/flowvisor/config.xml Trying to generate SSL Server Key with passwd from scripts/envs.sh Generating cert with common name == user keytool error: java.lang.Exception: Key pair not generated, alias already exists Exception in thread "main" java.lang.NoClassDefFoundError: org/flowvisor/config/FVConfig Caused by: java.lang.ClassNotFoundException: org.flowvisor.config.FVConfig at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: org.flowvisor.config.FVConfig. Program will exit.

It seems that the code is not compiled or that there were errors during code compilation. DId you manage to compile the code successfully?

yes.. My build was unsuccessful.

It gives me error like:

---

ant Buildfile: /home/netforall/flowvisor/build.xml

init:

compile: [javac] /home/user/flowvisor/build.xml:60: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

dist:

BUILD FAILED /home/netforall/flowvisor/build.xml:74: /home/netforall/flowvisor/dist/flowvisor.jar is read-only.

I believe the default permissions should have been correct. But probably it has got changed somehow. (as it is an older version which you are using, am not sure why) I guess you have to change the permissions of flowvisor.jar by using: chmod 664 flowvisor.jar (or something similar which gives you more than read permission) and could you please try building again which should be successful and then later try generating the config.xml.

I gave permissions to the flowvisor.jar file and had a successful built.

I also installed it. I want to run flowvisor in the same user that I have used to install it. I didn't create another user(flowvisor) as it is stated in the installation manual. Is it possible this way?

[alshabib]

Sure that can work as well, but it is less secure.

Is your problem now fixed?

I have installed it but with an error. When I start FV. a message appears:

Starting flowvisor with the configuration stored in DB If DB unpopulated, laod config using 'fvconfig load config.json'

then i run fvconfig load config.json and it give me the following error: Could not find /usr/etc/flowvisor/envs.sh: dying...

[alshabib]

Did you run sudo make install? Also why are you using such an old version of FlowVisor?

I did sudo make install. Settting fvuser and fvgroup to my username (netforall) in my case.

And about the version im using 0.8. Is this issue somehow relates to the verison??

[alshabib]

It should not be related to the version number. Could you send the output of sudo make install?
