EoMPLS CE configuration basic question

My company is going to switch to MPLS as our WAN service provider. It is pure L2 technology according to the provider and the handoff will be Giga fiber Ethernet. But I dont need transport VTP, CDP and STP between sites.
So I dont think that there is a need of trunk port to tunnel port and q-in-q configuration. Right?
I plan to plug the link into L3 switches on both ends and configure IP address on L3 just like a point-to-point link. Do you think this whould work? Is there any MPLS related configuration required for this scenario? Do I miss anything?
Thanks

Hello Ming,
Regarding DSCP bit preservation across the MPLS backbone, well, you have the choice of either remarking it by the Service Provider or let it be carried "as it is", it all depends as to what you want.
Infact NOT honoring the cusotmer QoS is more beneficial to the Service Provider in some cases, imagine if the SP honors your QoS... you can buy a "Standard" service and mark the packets with "priority" bits and avail of "Premium" service... so many SPs don't usually honor customer QoS, be it IEEE 802.1p, IP ToS/DSCP or MPLS EXP...
So answering your question clearly, Yes QoS markings would be preserved...
Let us know if this helped...

Basic Questions About Compiling Source

Hi!
I have some very basic questions about compiling source on 10.6. BTW, if the unix discussions still exist, they've hidden them pretty well, so I hope I'm in the right place for this!
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
Once you do figure out which compiler to run, the process is supposed to go like this, right?
./configure
make (or whatever)
make install
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.
$ ls ~/Downloads/arm
ChangeLog
README
armrc.sample
setup.py
LICENSE
arm
install
/src
Maybe it's that 'setup.py' file? What are you supposed to do?
Of course, it's not only this one that's given me trouble. Sometimes the readme will say I have to edit a certain file for my system. Are there just a few standard changes you always make? Or is it...how can I put it...complicated? How do you find out what's needed in those cases?

This is the place for UNIX discussions. If you have developer-related questions, there is a forum dedicated to that as well: Developer Forums
First off, you simply cd to the source dir, wherever it may be - in my case ~/Downloads/source/ - and during the install process, everything will be installed in its proper dir, right?
Yes. Hopefully the project you want to install follows standard conventions. If so, you can do "./configure", then "make", and finally "sudo make install" to install the software into "/usr/local".
How do you know which compiler to use? There seem to be several: make, gmake, gcc, g++, etc...
The make file will figure that stuff out.

make (or whatever)

Yes, with the addition of "sudo" before "make install" because "/usr/local" is owned by root.
But this doesn't always work for me. For instance, I'm trying to compile 'arm', but it doesn't seem to have a 'configure' script.

arm? You mean "arm (anonymizing relay monitor) - Terminal status monitor for Tor relays." You really don't want to be messing with that stuff. The only people involved with Tor that are trustworthy are US Navy intelligence who have their own uses for it. If you don't understand it as well as they do, best stay away.

Some basic questions on File Adapter

Hello all,
I have some basic questions on XI and File Adapter and hope you can help me. Any answer is appreciated.
1. Can I use NFS transport protocol to poll a file from a machine in the network, which is not the XI? Or do I have to use FTP instead?
2. If I understand it correctly - when using the FTP-File Adapter, XI has the role of a ftp client. I have to run a ftp server on my distant machine. XI connects to FTP-Server and polls the file.
Can it also be configured the other way round? The scenario I think of would be: FTP client installed on distant machine, which connects to FTP-Server(XI) and loads up a file. So XI would act as FTP Server.
I know this works, if I install a ftp Server on the computer my XI runs on, and use the NFS-File Adapter to observe the folder. But I want to know, if I need a second, independant ftp server for this.
3. And last but not least: When do I need the active ftp mode instead of passive?
Thanx a lot for your answers!

XI cannot act as FTP server, but it is always a client. When XI is reading (File sender adpater) when XIis writing than it is File Receiver adapter

It depends on your firewall configuration. The best and the fastests is active mode but not always available.

Basic questions about CISCO IOS

Hi everybody, Jack here,
I have some basic questions about the Cisco IOS, could someone help me addressing some of them please? Any feedback would be greatly appreciated.
Basically, I have two IP addresses assigned by our Cable ISP. From what I understood you can configure a Cisco router for multiple IP addresses using the IOS, thereby allowing someone like myself to take advantage of having multiple IP addresses. This may seem unnecessary to some, but I've always wanted to put the 2nd IP address to use, since after all, I've been paying for it.
I was just wondering if someone could confirm that what I'm hoping to accomplish is indeed within the capability of the Cisco IOS (i.e. Fully utilize my 2 IP addresses). As well, if someone could kindly suggest a decent CISCO router for online gaming home use that would be super awesome!
Thank you all so much for reading through the wall of text:)
Jack

Jack
Certainly using multiple IP addresses is in the capability of Cisco IOS routers. How they can be used depends on the relationship of the IP addresses. I am assuming that we are talking about IP addresses assigned for the user to use and that the IP address for the ISP connection is not one of these that we are talking about.
If both of the IP addresses that you have been assigned are within the same subnet then you would assign one of the addresses to the router interface to establish IP communication between the router and the ISP and to enable Internet connectivity for the devices inside your network that will use the router as their gateway to the Internet. The other address that is assigned can be used for address translation and in particular for static address translation which would make one of your devices inside to be reachable for connections initiated from the Internet (if that is something that you might want to do).
If the addresses that are assigned to you are in different subnets then you could assign one address to the outside router interface and assign the other address to the router inside interface. Or you could use the second address for address translation.
I do not have much expertise with online gaming, but I would think that either the Cisco 881 router or the 890 router might be appropriate for you. If 100 Mb connection is sufficient then probably the 881 would be the one to look at. If you need Gig connection then look at the 890.

Basic Questions About CSM

Hi,
We have a CSM installed in a 6513 chassis working as our load balancer for web servers. I have a few basic questions:
1. The current default configuration of probes on our switch indicates 2 minutes interval, 3 consecutive errors before marking real server failure and 5 minutes between probes of failed server. This setting results in 10-12 minute switch over delay in case one server fails.
In one of the Cisco papers I read that the default for these parameters in CSM is 8 seconds, 2 retries and 5 seconds, respectively.
My question is what is the default settings for probe parameters and is there any recommendation for a optimal settings? (I am going to use 1min, 3, 15seconds resulting 0.5 to 1.5 minutes delay and want to make sure there is no concerns with that)
2. Does the sticky timeout affect the switch over delay time? My understanding is that sticky timeour applies to the normal condition when all legs are up and in case of a failure, the traffic will switch over regardless of an existing active sticky session. Is this correct?
3. What is the exact definition of a "connection" in a load balancer? Is there any way to estimate or predict the number of connections for a specific traffic load (e.g. number of connection per user)?
Thanks for your response,
Ali

There is an ASK THE EXPERT session currently, if you have more questions, please join us there.
Regarding your current questions :
1/ The default for an icmp probe is 120sec, 3 retries and 300sec for failed.
You can use whatever values you think is necessary for your environment.
However, you need to remember that a probe generates traffic and each probe require process CPU time to send and receive.
With a lot of servers you probably want to avoid low frequency values.
I think your suggested value of 1 minute is ok.
2/ the sitcky timeout does not affect failover.
However, you should be aware that if a server goes dowm, the CSM will send NEW connections to the other servers. But active connection will stay with this server even if down. To change this behavior use the 'failaction purge' command.
3/ A connection is a flow. It is defined by a SRC IP, DST IP, protocol, SRC PORT, DST PORT.
Within a connection you can send 2 bytes or 2 Gig.
So, it is difficult to link the 2 values.
ie: when you load a webpage, if you are using http 1.0 you open 1 connection for every object (text, gif, banner, ...) but with http 1.1 you can download all the same objects in a single connection.
Hope this helps.
Gilles.

Basic Questions from Prospective Lion Server Switcher

I have five servers I am running right now using Windows 2003 Server and various 3rd party packages. Several years ago I became a Mac fan, moved all of my client based stuff to Mac, and now want to start moving my server based equipment to the OSX platform.
I stopped by my local Apple Store, and they had a version of OSX Lion Server running on a MacMini, but couldn't seem to answer the most basic of questions because as their business people stated "We are not Server Certified" ... they recommended I talk to an outside consultant to get these basic questions answered which seems a little extreme.
So I'm hoping the group can help.
(1) I read through most of the Lion Server Advanced Administrative manual. Lion server appears from the manual to do most of what I need. However, when I tried doing some of the functions in the manual on the demo Lion Server at the Apple Store, many of the functions I wanted to do did not seemed to either be installed, or their were buttons missing in the Server App. I do not know if this was a permission level problem, because the account I setup for myself had administrative rights.
(2) In the mail app, it only appeared you could setup one mail domain. It appeared you could setup virtual domains and users through the user app, but not through the mail domain itself?
(3) I could not find any where to enable DNS services. The manual seems pretty straight forward in turning on DNS, but the Lion Server I saw had no DNS services running, or any way to enable them?
(4) Same for mailman listserv type function ... manual seems to be straight forward on enabling under the mail server, but again, no signs of the settings or enabling under the mail service.
(5) Under the mail app, didn't find any way to setup alternative SMTP ports ( I allow now Port 26 besides the standard Port 25 and SSL ports for my users.) ... I find port 26 gets past most firewalls at hotels etc. Didn't see any way to control SMTP authentification too.
(6) Under the Lion Server tech description, it talk about a built in web editor, saw nothing of the kind.
So did the apple store have a limited install or am I missing something that the lion server manual does not match the capabilities of lion server.
Love to get a straight answer before purchasing hardware to replace 5 present machines.
Thank you.
David

Thanks for quick response. Indeed, in hindsight, it appears that they had only installed the Server App, but not the Server Admin tools.
Unfortunately, I am not a system admin, but I played one on TV <grin>
All kidding aside ... I'm willing to learn, but would need most of the basics controlled through the GUI ... and then feel comfortable reading up and editting configuration files and running commands from the Terminal.
On this line, is there good documentation of this, or is this something that you know because you are familiar with Unix? ie something like the alternate port issue ... is this something in the GUI, or something I would have to edit via Terminal?
Just trying to make an informed decision before jumping platforms.
Thanks
David

Basic questions about PCI-DIO-96

Hi
I am trying to write code to control a digital I/O board for the first time.
I have a legacy board, PCI-DIO-96, as the code implies, it is a PCI digital I/O boiard with 96 I/O channels
My first question is, what would be the drivers and development platform I should download for this board?
I am planning to write my code in C++.
The second question is, I am trying to write a very simple application to drive 96 solenoid valves through the board.
Basically I need to use the board in output mode only. No data gathering here.
The application basically needs to open and close these valves for a specified number of milliseconds. So basically,
I would be sending either 0 or 1 through the output channels, that's
it. If I send a "1" signal through the board, does
that
"toggle" the channel, meaning the channel will keep sending "1" through the ouput until I send another signal, or do I need
to send the "1" signal every few milliseconds to simulate a constant "1" signal?
Does anyone have code samples or know where I can find code samples illustrating this simple case?
It would be greatly appreciated.
I realize these are very basic questions, but I am new to hardware programming and I am on a deadline.
Thank you
Kiko

Hi Kiko,
Great to see that you are asking questions here first, you definitely came to the right place.
Since you are starting with a clean slate as far as knowing how to use this board we can start off on the right foot.
Download the latest version of the drivers for your board. You can find the drivers here: NI-DAQmx Version 7.5 for Windows 2000/NT/XP
After you have downloaded the drivers, power down the computer,
insert your board, and power it back up. The board should now be
recognized and the drivers will install similarly to any new hardware
would in Windows.
Now it's just a matter of learning how to use the commands that you need to get started.
I would recommend starting in the example files. You can find
some excellent examples that should do almost exactly what you are
trying to do by looking in this path:
C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Generate Values
Look for the example that best represents what it is you are trying to
do. You will notice that all of the examples have a general flow
to how they call the board.
Create a Task and Define what that task is meant to do
Set the configuration for how exactly that task will operate
Read/Write various values until a condition is met
Close the Task
Error Check all operations to assure that everything is working properly
It's really not all that difficult and should you run into any problems or errors don't forget to search ni.com or the forums to see if others have run into similar issues to what you are facing.
Regarding how the states for digital lines work. The short answer
is that if you set a digital line to high it will stay high until you
set it back to low and vice versa. For more details on everything
digital check out our Digital Fundamentals page.
Best of luck!

Basic questions about Notes domino connector

Hi,
I have a very basic question about the Lotus Domino connector for OIM. We have a requirement to provision accounts into the domino mail server and while doing that also update some information directly into a separate nsf file.
I checked the documentation and it seems while configuring an IT resource, we need to give the Mail DB path, and thats the only place where it refers to it.
Could you guys please let me know if this can be done? Can I write directly to a different nsf file, which is not like provisioning to the complete mail server. So the other attributes in the IT resource may not be able to be set up as its just the file I need to provision into.
Looking forward to your response.
Thanks, M

Hello folks, please share your experience working with the lotus notes connector.

Basic questions in SRM for Workflows+need material

Hi All,
I have developed Workflows in SAP R3.I am very new to SRM. I have following questions -
1. What is the use of BADI when we implement Workflow? My understanding till now is to provide all approvers to the
   Shooping Cart.That means for workflows without approval we dont need to BADI to implement.
2. Is there any other concepts more i have to know? Like in R3 Event will be triggered with help of change doc, status mang., LIS exceptions and all through SWEC tx. is it same in R3?
   Sorry to ask very basic questions.
   Can anyone provide me step to step guide to configure SRM workflows and Cookbook for SRM?
   My Email id is [email protected]
   It will be very helpful for me.
   Thanks in advance.
   Ashwani

Hi,
1.All the n step workflows(where approvers are determined dynamically) in SRM can be implemented only using the BADI "BBP_WFL_APPROV_BADI".the main purpose of this BADI is to fetch the Approvers/agents for the workflow.In addition to the n step WF,you also have no approval, 1 step and 2 step approval workflow in which the agent assignment can be done directly(no BADI reqd) and this is applicable for all types of business objects i.e. Shopping cart,Bid etc.For more details refer the foll link;
http://help.sap.com/saphelp_srm40/helpdata/en/17/40a86c773d6c41801d78af1a34b90f/content.htm
2.Work flow concepts are same as in R/3.So techincally you can create your custom workflows in the same way.
Do let me know if you need any further help.

Pls reward points for useful answers.

Basic question inbound / outbound and source service (ASA 5505)

Hi there,
I'm new to the ASA 5505 appliance and have a few very basic questions. Hope I get some responses and not flamed for being a total newbie. :-)
Inbound versus outbound: I'm having a difficulty understanding the inbound versus outbound terminology. Can somebody please clarify? For example, if I want to block all http traffic from hosts on the inside to the internet but allow all https connections, intuitively I'd configure a rule to block outbound (= outgoing) traffic for the http protocol for the inside network. However, it seems as if I have to add this rule for inbound connections. Why is a connection from a host on the inside to a web server on the internet considered an inbound connection on the inside interface?
When I add a rule, I've got a "service" field and a "Source Service" field in the "More Options" section. What's the difference? Do I have to set both to the same value?
Your help is greatly appreciated.

Hi Ralf,
Yes, if you put a deny http, it would drop all packets for destination as http port, but be mindful that when you apply an access-list on your inside interface, it automatically activates the deny ip any any right at the bottom, you would be able to see that in the ASDM. So for the users that need be allowed access to the http, needs to be explicitly allowed http access, so your correct configuration would be:
access-list inside_access_in deny tcp host 192.168.1.1 255.255.255.255 any eq http
access-list inside_access_in permit tcp any any
access-group inside_access_in interface inside
This would block 192.168.1.1 to go to internet, but allow all others.
Second question, i haven't chceked the ASDM, but just remember out of memory, that this service option should be the protocol, whether ip,tcp,udp,esp or gre etc.
Moreover always try to block connections as closed to the source as possible, this would mean, if you want to filter traffic going from inside to outside, that should be done on the inside interface not outside.
Thanks,

Assorted basic questions

Hello,
I have recently bought an iPhone, and after reading the User Guide I have many small basic questions. I'm using an iPhone 3GS together with Windows Vista. I wouldn't like to clog this forum with multiple topics about small things, hence everything being here:
1) Is it possible to save .pdf files to the iPhone? I have limites web access, and I often use a few pdf files. I would rather use storage space for them than downloading them all the time (even with cache). If this isn't possible without external applications, which reliable application can save documents such as pdfs and docs to the iPhone?
2) The iTunes Store is not available in my country for buying movies. Given how I'm using Windows, is there any way to transfer movies to my iPhone? Whenever I try dragging a movie to iTunes on my computer, nothing happens.
3) In order to access my work's network from outside computers, we need to set our browsers with specific proxy configurations. Is it possible to set a proxy with Safari? Is there any way of doing that at all with the iPhone?
4) I have began using iTunes in order to move my music to the iPhone, but iTunes and the iPhone automatically organize everything based on song title, while I have organized everything based on filename. Is it possible to make the iPhone and/or iTunes display and order songs by filename? I could manually rename everything, but with nearly 1000 songs...
5) Is there a Find command on Safari, corresponding to control F on other browsers? When reading long pages, I miss being instantly able to locate a specific word.
6) Is it possible to use the recorder built withon the iPhone to record a phone call? Is there any application capable of doing so?
7) I have set my Gmail account to the e-mail function, but I have noticed that, unlike the Gmail website, the e-mail application doesn't keep conversations together (like what the iPhone does with messages, keeping a message and its replies together). Is there any of setting the Mail application to do that?
Thank you.

1. For your pdf and other files I recommend the application Files. Files light is free and has a 300mb limit I think. The paid version is limited by your free space on the phone. It views Excel, Word, PDF, JPG, music, and other files. The transfer is by wireless.
2. Files might work with your movies, but they must be in a format the iPhone supports.
Video formats supported: H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; H.264 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Baseline Profile up to Level 3.0 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
6. No, the recording of a phone call is not supported nativly by the iPhone.

Neophyte Asking Basic Questions

I must be thick - can't find answers to some really basic questions:
1. To distribute Compressor tasks, is Qmaster and Compressor required on all participating Macs?
2. Are they required to be exactly the same version across the participating Macs?
3. Are they required to have unique serial numbers? (I tried to start Compressor on a second Mac that had been installed from FCS 5.1 Crossgrade package that resides on original Mac - all that was on the second Mac was Compressor and Qmaster - Qmaster didn't seem to mind, but Compressor gave me a warning message and terminated....)
4. Assuming the above issues have been resolved as required, does Compressor have to be started on the "Services Only" Mac in order to assist in the processing?
Again, my apologies for the level of these questions....
Stan

1. Yes, plus, if you're sending Compressor tasks from Final Cut Pro, all computers in the cluster are required to have Final Cut.
2. It depends, but usually, yes, all versions need to be the same. Qmaster 2.0 and 2.1 are not compatible with each other. 2.0.1 and 2.0.2 would most likely work. together.
3. I've always been working with Volume Licenses here, so I can't verify this, but as far as I know Final Cut Studio programs won't operate if an identical serial number is operating on the same network. As far as recieving tasks, I'm not sure serial number checking is done.
4. The answer to this question can be found in the Distributed Processing Setup Manual (open Apple Qadministrator -> Help -> Distributed Processing Setup), but in a simple answer, no, a QuickCluster, Services and Controller, and Services only computer can all be configured into a cluster (I'm pretty sure).

Basic questions on migrating from a controller-less setup to a 2504 controller setup

Hello,
I am new to Cisco networking so forgive me for my basic questions. Currently our company uses a controller-less setup with 2 WAP321's and 1 Cisco controller-less 2602e WAP. I am told I can reflash the Aironet 2602e to be used with the controller. My first question is, if I mount the controller and network it into my network to set it up, will it effect my current environment? I don't want a situation where I take down the current environment. If it will not harm my current wifi network then, should I be able to configure the controller fully and associate my new WAP Cisco Aironet 2602e to it without effecting the current environment? Thank you!

There will be no problem.
connect AP to switch and place it same place where it was to cover the same area.
Make sure that 2602 AP need minimum 7.2.100.0 version on WLC.
See the compatibilty matrix.

Basic question

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanks

Hi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps.
