SNMP Agent in Python -

-

i required snmp agent in python, listen on particular port , and responds basic snmp command (like gte, set, getnext ...etc)

if 1 have code please reply on post.

there's collection of snmp command responder scripts @ pysnmp web-site.

here's simple pysnmp-based command responder uses text files in /tmp mib data store.

from pysnmp.entity import engine, config pysnmp.entity.rfc3413 import cmdrsp, context pysnmp.carrier.asynsock.dgram import udp pysnmp.smi import instrum, error pysnmp.proto.api import v2c  snmpengine = engine.snmpengine()  config.addsockettransport(     snmpengine,     udp.domainname,     udp.udptransport().openservermode(('127.0.0.1', 1161)) )  config.addv1system(snmpengine, 'my-area', 'public', contextname='my-context')  config.addvacmuser(snmpengine, 2, 'my-area', 'noauthnopriv', (1,3,6), (1,3,6))  snmpcontext = context.snmpcontext(snmpengine)  class fileinstrumcontroller(instrum.abstractmibinstrumcontroller):     def readvars(self, vars, acinfo=(none, none)):         try:             return [ (o,v2c.octetstring(open('/tmp/%s.txt' % o, 'r').read())) o,v in vars ]         except ioerror:             raise error.smierror      def writevars(self, vars, acinfo=(none, none)):         try:             o,v in vars:                 open('/tmp/%s.txt' % o, 'w').write(str(v))             return vars         except ioerror:             raise error.smierror  snmpcontext.registercontextname(     v2c.octetstring('my-context'),          # context name     fileinstrumcontroller()                 # management instrumentation )  cmdrsp.getcommandresponder(snmpengine, snmpcontext) cmdrsp.setcommandresponder(snmpengine, snmpcontext)  snmpengine.transportdispatcher.jobstarted(1)  try:     snmpengine.transportdispatcher.rundispatcher() except:     snmpengine.transportdispatcher.closedispatcher()     raise

keep in mind script starter you, not handle corner cases.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
