Which is better lease line or VPN??

Hi..I need to connect 10 sites with no web portal,public users...which is better between lease line or VPN ..is there a need of firewall?...Does VPN also covers the L4-L7 securities ??..should I go for lease line or VPN ??
When I go for VPN, still there is a need of Firewalls to provide the L4-L7 securities if Web servers are there ...??
Please suggest me ..
Regards,
-Sanjeev

Yes for sure VPNs and firewalls are complementary technologies and both are required on most networks. To simplify you could acquire a UTM box that could offer you all this on the same hardware unit, resulting in reducted TCO.
Leased lines vs. other medium discussion is not about the 'better' or worse. You have to balance between reliability/availability and COST. A properly desgined MPLS VPN (ISP) could offer a pretty decent uptime (just make sure you have an appropriate SLA with the ISP).
Please rate if helpful.

Cable vs Leased Line which is better

Looking for info on what service would be better to use. I'm controlling 18 sewer pump station with radios now but want to make it faster and do some real times. At this point i'm polling each location once a minute and i want to see it in realtime.

We have worked for two seperate customers where we installed ethernet modems on lease lines and connect to the remote PLC's using a Modbus driver and selecting Modbus ethernet mode and have had good luck with that. The poll rates we have set are between 1 to 3 secs. The server on one site currently is looking at 9 sites.
We had some situations where the lease lines were being abandoned so we have now switch most of the sites to wireless ethernet radios and are having excellent results.
We have not tried cable but using the radios and ethernet have worked well. Previous to the conversion to ethernet modems we were using serial modems. With the serial modems we needed to transfer all the data to a master PLC and then have Lookout Poll the master PLC. The poll times there were longer due to the nature of the polling updates.

Which is Better? Mac or PC?

Which is Better?
Intel iMac Mac OS X (10.4.5)

Hello,
I'm not going to argue that a Mac is better, but I do have a response to:
looking computers and the software is great however
they have major compatibility issues. for example
many websites do not support mac's Ex.
www.aircanada.com
I have never had any problem exchanging documents or viewing web pages with the Mac.
All my document exchanges have worked flawlessly, and work going both to and from Windows PC's.
But, you need to make sure you are using the right program on the Mac if you want to share files with PC users.
As for the website compatibility, the site you provided as an example will work just fine. They just don't want you to know it.
What that website is doing, is running a check to see what web-browser you are using. Beyond that, they are also running a check to see which computer you are using.
So, what you need to do is make sure that your browser tells their website what it wants to hear.
So, in Safari, you can use the "Debug" menu to have Safari report itself as the Windows version of Internet Explorer.
Go to the Debug menu, then pick "User Agent", then choose: "Windows MSIE 6.0".
If the site still won't load, then go to the site first, and perform the selection again from the Debug menu.
Basically, what you are doing is changing what Safari identifies itself as.
Additionally, the website that you listed does list that it is compatible with Mac OS 9.0 or later. So, it should work provided you pass it's checks.
If for some reason it still won't work, contact them since they say that it is compatible with the Mac.
The only sites that absolutely will not work with a Mac are sites that use "Active X" to take over control of your computer or communicate directly with the operating system. Fortunately, those sites are getting rarer and rarer.
The only site I've run across in recent times that uses Active X is Microsoft's Windows Update site (which you wouldn't need with a Mac anyway).
As for enabling the "Debug" menu in Safari, if it is not already there, you can do that by:
Closing Safari
Open "Terminal" which is located at:
Hard Drive --> Applications --> Utilities --> Terminal
Then type the following at the command line:
defaults write com.apple.Safari IncludeDebugMenu 1
If you would prefer an automated method of enabling the Debug menu, you can always download the free Safari Enhancer program which includes a setting for this feature:

Which is better. . . a Canon Sure Shot or a Canon Power Shot?

I need to purchase a camera good enough to get good close-ups for items to sell on eBay. Which is better...a Canon Sure Shot or a Canon Power Shot?

Hi, leigh8389, thanks for posting!
If you're looking for a currently-produced digital camera, we would suggest purchasing a PowerShot camera. You'll find that our PowerShots offer the very best in macro capability, color reproduction, portability, and convenience for digital editing and printing.
For your reference, our Sure Shot line of cameras operated exclusively on 35mm film rather than digital memory cards, and was produced from the mid 1990s-the mid 2000s.
Additionally, please feel free to check out our Canon Direct Sales store at shop.usa.canon.com, where you can explore Canon's latest Powershot models; we hope this helps!

Which is better ASM or file system storage

Hi all, I need a urgent help from all u gr8 DBAs.
I have to give justification to my client that which is better to use between file based option ASM and why??
So can anyone give me some write up in this line?

Ok, how about this
Today's large databases demand minimal scheduled downtime, and DBAs are often required to manage multiple databases with an increasing number of database files. Automatic Storage Management lets you be more productive by making some manual storage management tasks obsolete.
The Oracle Database provides a simplified management interface for storage resources. Automatic Storage Management eliminates the need for manual I/O performance tuning. It simplifies storage to a set of disk groups and provides redundancy options to enable a high level of protection. Automatic Storage Management facilitates non-intrusive storage allocations and provides automatic rebalancing. It spreads database files across all available storage to optimize performance and resource utilization. It also saves time by automating manual storage tasks, which thereby increases their ability to manage more and larger databases with increased efficiency. Different versions of the database can interoperate with different versions of Automatic Storage Management. That is, any combination of release 10.1.x.y and 10.2.x.y for either the Automatic Storage Management instance or the database instance interoperate transparently.

Which is better with a NAS: using Sharing or Library location?

So I've got my brand new NAS up and running (Netgear ReadyNAS 104).
It has a Music folder with an iTunes server so I can use it as a Shared Library.
But I can also point my iTunes to the NAS and use the library directly from the NAS.
So which is better? Using the NAS as a Shared Library or use the NAS as the primary Library?
I want multiple devices (primarily Apple devices, but perhaps also a Windows laptop) to be able to use the media.
What about library management? Like when ripping an audio CD. When I use the NAS as a shared library, do I need to manually copy the CD to the NAS iTunes share and have iTunes re-scan?

Well... I downloaded LibreOffice and Writer2ePub and openned my Atlantis doc in it and converted to epub file. The good news is it didn't cost a dime.
The bad news is one image is now tiny which is odd because it was 600 dpi so I would think it could be displayed larger, not smaller but maybe the epub conversion downsizes a higher res image (some are 300dpi).
The cover image shows up in iBook as a wide and short image. The cover itself is tiny and then it just fills in black for the rest of the screen width. I used a large, high res image.
Then there was something with the TOC. It created a good TOC but then there's another page with a none hypertext version and a big rectangle error message and the TOC only shows about half of the chapters.
There was some advice on the internet about centering images in iBook. It seems that iBook doesn't recognize text justification coded in a document. So you have to embed another element on the same line as the image (html stuff) and give it a center alignment tag. I haven't done any html ebook stuff so I may not be explaining that the best way possible.
So, I'm going to take another look at my iBook Author version and see if I can live with that. If not I'll probably try Pages although I don't know what other problems I'll run into. Fun, fun, fun

Advice Needed... which is better?

Hello... I am not a computer 'genius", but not a complete "computer idiot' either. I have a question, and then I will give my reasoning, because maybe it matters in the decision.
Which is better, a PC (Gateway) with 6GB Ram, i5 processor, 1.5TB HD or an Imac 4GB Ram, i3 processor, 1TB HD??
Basically, I have had a Dell 2GB Ram desktop for 7 years, which suited me fine. I ran CS3 on it with no problems. I recently had a virus, and had to swipe my computer, and when I re-installed Adobe, my Premiere Pro will no longer allow me to edit properly (audio plays fine, while video lags and skips around during viewing). I know it is time to get a new computer either way, and a few friends have told me that I really shouldnt be running Premiere Pro on 2GB of ram, and suggested at least 6GB.
I found a Gateway for $650 on bestbuy site with the above specs... but then someone I know, told me I would be better with an Imac with the specs above. Is that possible that a 4GB mac would run better than the 6GB PC?
also.. will CS3 work on the Windows 7 PC, but if I get Mac system I will be using CS5.
I use Photoshop, and Premier Pro for simple music video editing (5-6min videos). I do not do anything major..but want to at least be able to view what I am doing.
thanks

While I don't agree that Macs are as inferior as some here claim, for your purposes an i5 iMac is certainly inadequate. The i7 quad core iMac is something else again; it can take up to 16GB of RAM, which is plenty for most applications. The particular i7 CPU in the iMac is also quite capable with a number of performance enhancing technologies on board. The big problem with the iMac, though, is that it comes with only one internal HDD; there is an added SSD option, but in my opinion it's still too expensive. For video you should have at least two internal drives and preferable three or four, as others here have said. External drives are generally slower, even if you use a FireWire 800 port. Sometime this year Apple may add a Thunderbolt port to the iMac, as they have to the MacBook Pro. This will be a game changer for external media, with unheard of flexibility in connectivity and the performance of Fiber Chanel at an affordable price. There are already external RAIDs coming to market with Thunderbolt connections. However, there is no date certain for such an iMac refresh.
For even semi-serious video you need some heavy iron, whether Mac or PC. There are some great Mac Pros available now with up to 12 cores on two 6 core Intel Westmere processors; however, even though I am a Mac fan, I'm sure you can build or get a BTO Windows PC with comparable specs for less. I suggest a minimum of four modern CPU cores to handle multi-threading and multi-tasking chores. At least two fast internal hard drives, four is preferable. And, of course, the more RAM the better, though this too will raise the price. You may not get the maximum RAM right away; the important thing is that the motherboard be able to support substantial RAM upgrades so that you can grow into it.
The challenge, even with PCs, is that a number of core technologies are changing right now. SixGb/s hard drives are becoming available but it would take a high-end and relatively new motherboard to support them properly. So, besides the question of which computer to get, you have to consider when to get it. If you need it right now, that narrows your choices somewhat because you cannot wait for these new technologies to come on line.
The most important thing to consider, though, is not to cheap out. Presumably you will be doing some real work on it, so think of this computer as an investment in your own future. Buy the most computer you can afford and a little bit more. Oh, and there is a new Version of Final Cut Pro coming out soon that will be Intel only and 64 bit capable, so Apple is moving ahead on this front, too. Remember, not all of Adobe's CS apps are 64 bit yet either. It's just one more technology in transition.
One point I will concede, however, is that Windows has better video drivers than OS X. Even on a Mac, running Windows in Boot Camp delivers better video frame rates than the Mac versions of the same apps running in OS X. So, for reasons of cost and better video support, a Windows PC is probably the way to go. PCs also have it over Macs in the number of options available. If you are not a techie yourself, I agree as well that it is probably a good idea to have someone who is built it custom for you. Of course, with a custom PC you won't get the kind of warrantee that comes from Dell or Apple, but the person who builds it for you will probably be able to service it as well.
Ultimately, of course, your budget is likely to govern the kind of PC you get more than your preferred specs. But even with Windows PCs you get what you pay for. A cheap PC is just that, a cheap PC. Inexpensive PCs are affordable because they use inferior components. Keep that in mind.

Tech Specs of the audio input jack? (which is better, an iMic, or the MBP?)

Well because the iMic has such a cheap sounding/terrible audio output....
http://discussions.apple.com/thread.jspa?threadID=2132385&tstart=0
....I am trying to figure out which would be better for the audio INPUT?
I am surprised to see that both the iMic and the combined jack on the 13" MacBook Pro seem to record in stereo, but technical wise, which is better? I DO know that the iMic is better for non-amped mics, that the iMic will pre-amp the signal where as the MBP will only accept line-in signals. So other then that, which is better?
Thanks,
Scott

Well, I sent back the iCrap...I mean iMic. I had to take a loss of $10 but oh well. (stupid apple return policy.)
Anyways, my solution was to buy a similar adapter off ebay for only $7. This USB interface is not a brand name one, it is one of those "china knock-off's" but it works. The Audio output it a lot louder but still slightly distorts like the iMic. However, the audio input works just fine. So my solution is to use BOTH the external USB interface, and the jack on the MBP at the same time. That will give me the best of both worlds. AND, it only cost $7 and came in 3 days, vs the adapter I bought from apple that coast over $35 and took a MONTH to ship.

Options for QoS on 2 meg PPP lease line.

Hi,
I have a 2 meg PPP data lease line bet my HO and BO. I need to know the Qos options, I can configure to run voice over the same link. I want to reserve 384K to voice traffic.
Will auto qos be of any help ?
Thanks

SQL Loader or UTL_FILE , Which is better ??

Hello All,
In my system I have to Download the data from a file each day in some table.
The file is of fixed format. And the number of records (lines) in the file is not more than 1000 (say) each day.
I would like to know for such scenario what will be better to use, SQL Loader or UTL_FILE package to read the file?
DB - Oracle Database 10g on Linux platform.
Thanks & Regards,

Subject: Re: SQL Loader or UTL_FILE , Which is better ??
Hey,
My control file 'ATTENDANCE.ctl' is as follows
load data
infile 'C:\DATA\06012007.CAP'
badfile 'C:\DATA\atncap.bad'
append
into table NIS.atncap
COMP_CODE constant 'SP',
TXN_SRNO sequence(max,1),
TXN_DATE POSITION(05:12) date 'MM/DD/YYYY' ,
TXN_ATDATE POSITION(05:16) date 'MM/DD/YYYY HH24:MI',
TXN_EMPL POSITION(17:24) INTEGER EXTERNAL,
TXN_TIME POSITION(13:16) ,
CREATED_BY constant '---',
CREATED_DT sysdate,
MODIFIED_BY constant '---',
MODIFIED_DT sysdate,
TXN_FILE POSITION(05:12) INTEGER EXTERNAL,
TXN_INOUT POSITION(26:26) INTEGER EXTERNAL
and sample data from my file which is to be loaded is
CC000601200707300025831201FF09D071
CC000601200708330025836601FF09D17F
CC000601200710260025830001FF09D271
CC001201200718480025836201FF09D374
CC000601200719100025836601FF09D47B
which contains some flags, date, in/out times, employee code etc. and the positions of all the fields is fixed. The file is generated on daily basis with system date as the file name.
i.e. above data is from file '06012007.CAP'. We can easily see the date field is at positions 05 to 12 in the file.
So, for this purpose each time I have to update the control file for 'infile' parameter.
Thats what I said in my second post.

Metro Ethernet vs Leased line

Guys,
I'm setting a proposal for WAN link. there will 2 option, 45 MB leased line and 100 Metro ethernet. I need to know what is the pro/cons for this 2 technology as i need to explain to the customer.
Do anybody have a link or explaination on this?
Thanks
Rezzo

WAN vs Metro
1) Future BW Expansion : Metro-E BW expansion is as very easy compared to adding leased circuits to the WAN.
2) Service levels : Since Metro-E is a service it has better service levels than a traditional WAN link.
3) Finally Cost: In most cases the BW cost derived per Leased Circuit to that of Metro-E Link is higher in most places.
What may make the choice of WAN more practical is the availability of WAN only and no Metro service in a area.
Plus if the customer is not at all comfortable with a shared infrastructure link like Metro-E.
HTH-Cheers,
Swaroop

Metro E'net vs Lease Line

Hi, I want to use Metro E'net and
Leased Line effectively within 4 campus
All the centers are having L2/L3 Switches and routers & WAN Links are running on OSPF as on date.
Existing Setup (2500 Desktops + 250 Servers)
1. Seperate Network ID / Internet connections / Servers for all places
2. Seperate VoIP PBX for all the places (This will work for IP / Trunks over WAN)
3. Seperate WAN Links for Connecting Different offices
4. Seperate Adminstrators for all the places
5. Seperate VLAN/VTP Server/Clients
6. Seperate Firewall for all the places
After Commisioned the Metro E'net,
Option: 1
1. Will Metro E'net be reliable having a single vendor ? If not, do we need to get from second vendor also ?
2. Can i merge all in to single network ?? Will this is reliable ???
3. Can we use VLAN/VTP information over Metro E'net ?? If so, is that secured ?? If not, to secure what needs to be done?
4. All the L2/L3 become VTP Server and rest all switches become Client mode
5. Can we forward VoIP Traffic over Metro E'net ?? (For IP we can propogate for Trunks required only WAN.. How do we do that?
6. Will Metro E'net can be used for L2 and L3 Functionality ? (If not, is it possible for split 8 MB to 4MB for 6 MBPS for L2 and 2 MBPS for Routing ?
7. Will QoS can be enabled on Metro E'net ?
8. Can we forward all the centers Internet traffic to single center?
If the above case is worked out, we will not use Leased circuit at all.
Option:2
1. Metro E'net will be used for VLAN/VTP's only
2. All the L2/L3 Becomes VTP Server and others will have Client Mode
3. routing will be used for Routers
Please advise which is good for a Corporate network and how can we impliment

Which has better export quality. imovie 11' or adobe premiere?

has anyone used both? which has better quality when you export it? I notice that imovie downgrades the quality when exporting by a LOT. It looks great inside imovie and looks terrible once exported!

Hi
I can only guess - (have no Premiere) but
Depends on what will be the end result. DVD or publish on YouTube etc. or saved on an USB-Memory to be Played on PlayStation 3 and alike.
If DVD - then most probably Adobe Premiere is better (if it can export interlaced video to iDVD) - iMovie'08 or 09 or 11 can not do this - they discard every second line resulting in a sever loss of quality.
I use
• iMovie HD6
• FinalCut any version
And they do deliver full quality over to iDVD
If other end results - then it most probably doesn't matter.
Yours Bengt W

1Mbps leased-line

We are having a 1Mbps leased-line, i want to know, what kind of technology that can be. Thank you in advance.

Hi ,
Leased line( WAN tech.) is nothing but permanent path to reach the destination.It is a dedicated line which has a bandwidth limit of 1 Mb in your case.
Telecom personal will take care of these
leased lines and ISDN lines.
Usually the setup will be as follows for leased line.
RTR A(Seraill)--V35 modem -----G703modem (local exchange) -------------G703 modem (remote exchange)--------V35 modem ---(serial)RTRB.
Most of the organization will use either leased line or ISDN as a back up for the primary leased line.
Thanks,
Satish

From leased line to individual laptops

execuse my ignorance , I need help .
I ordered a leased line to my building , will be available in 3 months , I wonder what equipments I need to allow my tenants log to internet using wireless connection from the leased line , I have no idea about the equipments needed , I highly appreciate your advice and sorry if I posted this in the wrong section.

You don't want to do this with Linksys devices. Linksys is for consumers. Providing a wireless network with Linksys devices for 40-60 clients which all most likely expect a certain quality of that wireless service may be possible if you know really well what you do and how to handle and troubleshoot the equipment.
Otherwise I would highly suggest to look at Cisco Small Business devices. Check here https://supportforums.cisco.com/community/netpro/small-business
And honestly: considering your first post I would highly recommend to get a professional company to buy, install and operate the network for you.
If you are trying to operate it yourself I would expect that you will be busy troubleshooting complaints of your tenants during the next couple of months. Clients are picky and often you will get complaints about nothing. Some are more serious and really involve your equipment.
Thus unless your tenants don't expect anything and would happily accept even downtimes of a week or longer until you have got it fixed yourself I would really suggest you look for a company to handle this for you.
Put the costs of that company in relation to the 100s-1000s of hours you will spend the next months for choosing the right equipment, buying it, find the best locations for the access points, configuring the equipment to give each tenant a good quality connection and fare share of the available bandwidth (otherwise two people streaming videos from the internet could bring down the whole internet for all others...), troubleshooting tenant's devices and your devices, find problems, replace and RMA devices, etc. etc. etc....
