It looks like either the socket was left open from an ungraceful shutdown last time you ran NOX, or another application happens to be using the port that jsonmessenger is trying to use. If I recall, that would be port 2703.
If you run "lsof -i | grep 2703" you should be able to see which application is using that port. If it is a zombie NOX (or some other program you don't care about) you can kill it and try rerunning. Alternatively (if a program you care about is using 2703), you can try to make jsonmessenger use another different port. I think the command for that would be "jsonmessenger=tcpport=<portnumber>" On Wed, Sep 28, 2011 at 1:33 PM, Rafael Lopes <rafaell...@gmail.com> wrote: > When i try to run two nox with the spanning_tree i get this error below. > > First: Ok > openflow@openflowvm:~/nox/build/src$ ./nox_core -v -i ptcp:6634 switch > spanning_tree routing > 00001|nox|INFO:Starting nox_core > (/home/openflow/nox/build/src/.libs/lt-nox_core) > 00002|nox|INFO:nox bootstrap complete > > Second: Error > openflow@openflowvm:~/nox/build/src$ ./nox_core -v -i ptcp:6635 switch > spanning_tree routing > 00001|nox|INFO:Starting nox_core > (/home/openflow/nox/build/src/.libs/lt-nox_core) > 00002|nox|ERR:Cannot change the state of 'spanning_tree' to INSTALLED: > 'spanning_tree' has an unmet dependency: > 'jsonmessenger' ran into an error: > bind: Address already in use > > any idea to solve it ? > > -- > Rafael Lopes Gomes: > - Msc.
