How to simulate up/down network packet loss, BW, delay from script or command line?

Before ipfw used to cover network QoS parameters simulation from the command line.
Currently, from Yosemite on, PF seems more limited, and only port redirection/restriction seems to be possible.
Network Link Conditioner can do it, but, afaik, not from command line (or script). Which certainly limits a lot for automated testing or other automated operations.
Options?

Thanks for this - I also have an OKI (a C5500) and this is a Godsend as I would struggle to replace it.
A couple of comments:
Points 6 and 7 should be switched - MacPorts wouldn't install until XCode was installed. You my also want to expand the XCode instructions to say that the App Store link downloads the installer and that you need to go into Launchpad and run it to fully install XCode.
The gsed installation also popped up and asked me to install Java (through Software Update). I did this and the installation of gsed continued and completed succesfully.
If wget is in the Downloads folder, the command you have to use it in point 8 should be prefaced with ./ as it's the local folder it will run from.
You have an extraneous line right below the wget command (sdff).
Otherwise, this is a really excellent procedure.
Many thanks,
Des

Packet loss when pinging from/to a cisco 3560e switch

I see Packet loss when pinging from/to a cisco 3560e switch. CPU utilization is normal.
Switches are running with IOS c3560e-universalk9-mz.122-35.SE5.bin.
Packet loss is observed for all the devices irrespective of directly connected or remote devices.
If i do self pinging, there are no packet loss.
I don't see any error on interface.
Can anyone please help me in resolving this issue.

how to get the MAC address of the additional 10G NIC with ILO command line?
thanks.
This question was solved.
View Solution.

Hi Bruce,
Out from what I can find on this network card is it not possible to get the mac address without a OS. I would recommend you to get/burn a Linux/Ubuntu live CD/DVD and run a Ifconfig in there.
Hope it helps you.

How do I get LR2 to "load from device" via command line?

Hi,
how do I get LR2 to "load from device" via command line?
I've got XP to load LR2 when a "camera" (and only a camera) is connected but really cool would be if LR2 would also import the pictures.

How to compile an .air app from the ADT command line?

Hi,
I would like to compile an .air app from the ADT command line.
Does anybody have an example?
I don't know how to add the AIR SDK path and a folder to it.
Is there a generator for the command line availabble?
Thanks

Correction: it seems that Applescripts and some similar scripts can be called from the command line using "osascript scriptname". I don't speak automator but you might like to try it. osascript seems to come with severe limitations though, for instance it doesn't allow user interaction such as dialogue boxes.

How can I import eex files into Applications EUL from the unix command line

How can I import *.eex and *.dis files into an Applications EUL from the unix command line?
Thanks

Hi
The simple answer is you either have to use the client tool DIS51ADM to import files using the command line (Discoverer Admin is a windows only client tool), or the Java command line which needs a browser.
In theory if you have a browser running on your Unix box you may be able to use the Java command line to make this work.
Best wishes

TMS reporting - Network Packet Loss

Hi everyone,
I am trying to see packet loss reports in TMS but there is no info there.
My network is : VCS 7.0.2 with movi, c20 and ex60 registered (SIP) to it and a TMS 13.1.2.
The vcs is a starter pack and the TMS is the demo version. I first registered the endpoint to the vcs and then added the TMS to the network. I the added the endpoints and vcs to TMS. In TMS I see the endpoints and info about them, but unfortunatelly no info in the packet loss report. I made a call between movi and c20 with packet loss but no info was shown in the report.
I am very new to TMS and I wonder if there is something I should do in order to make the endpoints send packet loss info to TMS.
I sshed to the endpoints and I can see the info about packet loss and jitter through the api.
The network described above is my test network on which I can do prety much everything on. I also have the same problem (this time with EX60 endpoints, VCS Control and TMS) on a customer network and on that network I really need to get this working.
Any help would be much appreciated. Form what I read the endpoints should sent this info through HTTP to TMS. Am I right?
Thank you for your help.

Hi Magnus,
Thank you for your reply. I checked the logs and I get some info over there. I have attached the log.
Do you know what doc should I check to see if Ex60 is supported?

How can I start a second window of a second profile through the command line?

I have two profiles set up, 'default' and 'second'. If both are already running how can I start a second window of profile 'second'?
firefox -p 'second' : opens a new window of the default and,
firefox -p 'second' -no-remote : tells me that firefox is already running.

I don't think that this is possible.<br />
You need to open this second instance (Firefox profile folder) with the -no-remote command line switch and that makes it impossible to open external links via the command line or via a double-click.<br />
You can only open a link in such an instance by dragging the link on the tab bar of that Firefox window.

How do I generate PDF and CHM files from the a command line in windows?

I am trying to set up a PC to build some documents during the night. I was looking for a way to get framemaker to generate PDF and CHM files via a command line in windows? How is this done with FrameMaker 12
Thanks for the help
Alex

Hi,
The part with generate a PDF via a jsx seems to work OK, except when FrameMaker decides that it will not work anymore. I must say I am not impressed with the stabillity of FrameMaker 12, there is room for a lot of improvement!.
I have given up on how to figure out how to get FrameMaker 12 to generate chm files via jsx scripts, any pointes are still very welcome.
The route I have taken is I make a RoboHelp project for each chm files I need to generate. The only thing this RoboHelp project contains is a link to the actual FrameMaker project I want to generate a chm file.
To make the chm I start RoboHelp with a script that
1) Opens the desired project
2) Sets the desired output chm files name
3) Generates the chm file
4) And finally quits RoboHelp
Below is a copy of the jsx in case anyone can reuse anything. And yes parameters are transfered via enviroments variable. I have later learned there is some way to read the parameters given at a command line but this seems to work so I stick to this for now.
// Get parameters
var RhProjName = $.getenv("RH_PROJ_NAME");
var RhChmName = $.getenv("RH_CHM_NAME");
var RhLogFileName = $.getenv("RH_LOGFILE_NAME");
var RhLogFile = new File(RhLogFileName);
RhLogFile.open("w", "TEXT");
RhLogFile.writeln("RH_PROJ_NAME : ", RhProjName);
RhLogFile.writeln("RH_CHM_NAME : ", RhChmName);
doc = RoboHelp.openProject (RhProjName, 1);
var sslmngr = RoboHelp.project.SSLManager;
for(var i = 1; i<=sslmngr.count; i++){
var ssl = sslmngr.item(i);
if(ssl.name == 'Microsoft HTML Help') {
    // Set the output location and file name
    ssl.setSpecificProperty("DestinationProjectName", RhChmName);
    if (doc.saveAll(true) ) {
      RhLogFile.writeln("saveAll returned TRUE");
    } else {
      RhLogFile.writeln("saveAll returned FALSE");
    if ( ssl.generate() ) {
      RhLogFile.writeln("ssl.generate returned TRUE");
    } else {
      RhLogFile.writeln("ssl.generate returned FALSE");
} else {
    // alert ("Found " + ssl.name + " dont do anything");
doc.saveAll(true);
RhLogFile.close();
RoboHelp.closeProject();
RoboHelp.quit();

How do I create Local Network Home Folders for Users from an Active Directory binding?

My situation is this... I run an iMac lab at my school. I have a server set up to manage the network user accounts in the lab. Currently, I can sucessfully create Local Network Users and log in to them from any of the iMacs. My school has an Active Directory set up for all the students on campus. What I'd like to be able to do is configure the server to allow the students to use their user names and passwords from their school accounts to log in to the iMacs and have it automatically build a network user folder on the server for them to use during the lab.
So far, I have been able to configure access for the Active Directory accounts to use the services on the server, mainly File Sharing, but I cannot figure out how to allow them to log into a user account on the client's machines using their same Active Directory credentials. I have even attempted to allow the user accounts to create mobile accounts, but that's not working out either. Entering indivual network user accounts into the server for every student every semester will be a nightmare. I'm sure there's a way to do it automatically using the exisitng Active Directory structure.
The live server is running 10.8.5 Server still, but I've also got a clone running OS X Server in case it matters. Please help!

ok reinstalled everything dns seems to be working have done sudo changeip -checkhostname and it says that both names match but then i started open directory and can't seem to get Kerberos started, i've tried changing it to stand alone then back again but it does nothing. I'm wondering why this would happen? i've tried adding a kerberos record but it doesn't do it just does nothing so i don't know what i'm doing wrong. I wondered if it might be a problem with the two network cards and dns as on ethernet one it is getting the dns name xserve.xxxx.ac.uk (which matches what the college server wants to call us) but on ethernet 2 gets xserve-2.local because it tells me that it already exists on ethernet one and renames it to this. I need to set up NAT so have ethernet coming in on port one and out again on port two. I wonder if my dns is backwards as its got the 192. address the NAT uses but its linked to the ethernet port one dns maybe this is the problem. would this cause open directory not to start kerberos?

How do I extend a network with an AirPort Extreme from an Arris TG862?

I'm using Comcast as my ISP, and after some issues with a previous Motorola modem, they supplied me with an Arris TG862 Router/Modem combo tower. I have two AirPort Extremes, one of which was previously connected to the old Motorola modem to send wireless into the house, but it only reached halfway, so I had the other AirPort Extreme in the middle of the house to "catch" the signal and then broadcast it out to the rest of the house. This worked fine for a while.
But with the new TG862, it doesn't seem to be an option. From what I've read, if I have the TG862 in one room (connected to the cable), AirPort Extreme #1 in the middle of the house, trying to join the existing network (or extend it?), and AirPort Extreme #2 in the far end of the house (to extend from AirPort #1), it won't work. Apple's "extension" technology isn't compatible with all other modems or routers, and even if it was, I'd have to somehow configure the TG862 to "allow to be extended."
So my question is, IF there is a desktop utilizing the TG862 as a direct connection (because it has no built-in Wi-Fi), is it possible to put the TG862 into bridge mode, connect one of the AirPort Extremes and have it act as the router so I can use AirPort Extreme #2 to extend that network out to the rest of the house? I want to ensure the desktop still has a connection, but there's Wi-Fi that actually goes out through the whole house.
The connected-to-the-cable-desktop is a PC; we have multiple iPhones, iPads, and anywhere from 1 Mac laptop to 1 iMac in the house at any given time.

Topic title pretty well sums up the question.
I have a TimeCapsule Base Station with two Expresses for extending the network through the house.
We're doing a 3 room addition, and there is not a convenient place to put an Express in a wall outlet in the middle room of the addition, but there's a perfect place to put an Extreme on top of a piece of furniture.
So, can the Extreme act as an "extender" only, in lieu of using an Express?
Hiya.
You can absolutely extend a network with an Extreme. I've got a 5th gen. Extreme extending a network created with a 3rd gen. Time Capsule. On the Extreme, you'll have the option to allow (or not) WiFi clients. I recommend having all units updated to the current firmware (7.6.1 as of this writing). Note that extending doesn't work in daisy-chain fashion, meaning that your Expresses or Extremes will each connect to and extend from the TC. As such, you'll want the TC to be in as central a location as possible to offer the best coverage.

What does this error message mean and how do I solve it? "Sorry, one or more of the following command-line tools was not found: /usr/bin/lsbom, /bin/pax, /bin/mkdir, /bin/chmod, or /usr/bin/update_prebinding."

When I try to open up this program, Pacifist, I receive this error message. Here's a screenshot. http://i.imgur.com/v717w.jpg What does this error message mean and how do I solve it?

It sounds like some of the Unix Executable commands were removed (or the permissions to those were modified) out of the /usr/bin/ folder. You can try opening disk utility and repairing permissions on Macintosh HD or you can reboot your computer and holding down option-r when it comes back up to reinstall Lion again. This will not delete your personal information or applications you have installed but it would be best to back it up to Time Machine before you do. The article on how to do this is here. (http://www.apple.com/macosx/recovery/) I have had to do this before and it works like a charm. It should fix your issue but grab a cup of coffee because its going to take about 35 - 40 minutes depending on how fast your computer is.
