Same problem. Install frenetic: On ubuntu 14.04.4 LTS
Patch for message KeyError: 'queries': The error appears to be in the pyretic/core/netkat.py file Replace the function json_to_classifier
def json_to_classifier(fname, qdict, multistage): from pyretic.core.classifier import Rule, Classifier data = json.loads(fname) rules = [] for sw_tbl in data: switch_id = sw_tbl['switch_id'] for rule in sw_tbl['tbl']: prio = rule['priority'] m = create_match(rule['pattern'], switch_id) action = create_action(rule['action'], multistage) try: queries = get_queries_from_names(rule['queries'], qdict) except KeyError: queries = set() if rule.has_key('queries'): pyrule = Rule(m, action | queries, [None], "netkat_query") else: pyrule = Rule(m, action | queries, [None], "netkat") rules.append((prio, pyrule))
rules = [v for (k,v) in rules]
return Classifier(rules)
same problem in latest branch on 14.04.
@chelobarreto can you provide right indent format? Thanks~
Check that frenetic is intalled, run frenetic from command line. If it runs then check whereis installed in mi case in /usr/bin/frenetic:
user@localhost#whereis frenetic /usr/bin/frenetic
Then update the path in /pyretic/start-frenetic.sh
I have the same issue with the provided VirtualBox VM. Frenetic seems to be missing in the VM.

I'm following this wiki : https://github.com/Resonance-SDN/pyresonance/wiki/PyResonance-overhaul:-Running-example-applications I solved the frenetic problem after going through the above discussion. But now I'm stuck here, please help...
running pyretic.py -m p0 pyretic.modules.mac_learner in the tutorial gives the following errors ./frenetic: No such file or directory. ERROR:pyretic.core.netkat.netkat:2015-12-07 10:32:03,111: Compiling with the netkat compilation server failed. ([Errno 97] Address family not supported by protocol)
Tried working cloning and running frenetic by frenetic compile-server --verbosity=error gives the following error when mininet boots up.
