Opnet Modeler - Link error between router and cloud, cloud has no transmitter? - opnet

I hope you'll be able to help.
Anyone aware why this is occurring? For the record, I am using 100BaseT (not ideal I know, just a placeholder for now), all the components are their "advanced" versions. Just measuring heavy FTP loads.
Any advice is greatly appreciated.

Geoserver basics - access services publicly on another web site (different from localhost:8080)

I am a complete beginner in Geoserver and anything connected with it and would appreciate help or pointing me in the right direction. For now I can get WMS and WFS running on Geoserver on localhost:8080/geoserver but I need services to run on something like https://www.mypage.com/service/ different for every new dataset (GetCapabilities documents, querying, GetFeature, GetMap...). Is there a tutorial on how to implement this (that I haven't found maybe) or could someone write steps on doing this? Any help is really appreciated.
Kind regards,
Mirta
At the moment I don't know where to start.

Log of all connections/queries via Parse

I'm working on optimizing an app that interfaces with Parse.com and was wondering if anyone knew of a way to monitor/log all connections and/or queries executed.
I've looked through the documentation and clicked around and can't see anything readily available so hoping someone can help.

how to do performance testing of fix protocol

I need to do FIX-API based performance testing.
Can you please let me know few way ahead.
Also if I need to develop the in-house plugin then please can you point in some direction that how to do that?
Also does any 3rd party tool like loadrunner or neoload directly support FIX-API protocol testing?
Thanks
This has been asked many times before in many different forums. Please leverage Google for keywords of LoadRunner and FIX for FIXML as aprpopriate
If you want to do a test in FIX protocol over a FIX connection you can try using the FIXRobot. FIXRobot allows to easily write the tests in python. You can include a loop in the test script to pump messages and calculate the perf statistics from your application logs writing some scripts.

How to use Proxies && Proxy

I appreciate your help
I've never had the need to learn proxies until recently,
basically I have a Java application and I'm unsure if I can just setup a program so that my computer changes to use a different proxy every few minutes (out of a few 100-1000 proxies), or if I need to have the java application directly connect to a proxy in order for it to use the proxy? then finally I want to connect to website with basic get requests etc.
if anyone could kindly explain the process in order to accomplish what I explained and/or suggest how to go about performing this?
Thank you very much!
you can start with SamProxy 1.0 it is very efficient proxy built in java
http://sourceforge.net/projects/samproxy10/?
you will need to update java JRE first.
There is readme File in project which will help you

Has anyone written Ruby code to programmatically modify their DNS?

There are a bunch of services (dyndns, nettica, etc.) that offer API's but I'm having trouble with Nettica's and I was just wondering if anyone has a nice gem suggestion for any of the DNS services... I'm not set on one or the other.
Thanks for any help in advance.
Chad
This just in, Nettica does work as intended, but you need to buy the bulk DNS service in order to enable the AddRecord API call....... wasn't documented clearly but their support was able to point this out.
