AP1410s and near-line-of-site

Could anyone tell me if a pair of AP1410s will work if the remote antenna is obscured by trees? If so, what kind of signal loss should I expect? If not, can you point me to an alternative? The distance between APs will be about 3KM.

Bob
General wisdom says no, as you say trees that impies more than one. Bridges require a clear line of sight to operate reliabley. your proposed bridge may work in the winter when the trees are bare may even still work somewhat when they leaf out in the summer but will definatly have trouble when they are wet after a rain.
But only a site survey will tell you what will work and meet you requirements.
good luck with you project.

Hate to say it. I isolated this to only be happening with email/Mail program. Then ran Sophos Virus detector on it and it did show a trojan virus in my email spam folder. I eliminated it ; ran disk utility a couple of times and I am good now. Spent the whole day on it though before I thought of using a virus scan... as soon as I started running sophos it stopped sending me the two minute timer as well--so just opening the virus software was able to disengage whatever was happening. My computer is all mac --no PC interface added at all. Hope that was that. Thank you for responding.

Near line storage and FCSvr

Our xraid is filling up quick, is there a cheap alternative to buying vtracks and stacking them for archiving footage near-line? We're eating up disc space at a furious rate. Is there a solution where we can take large amounts of clips and send them off to a separate system where they can be slowly retrieved if need be?

You can purchase cheaper External Disks (Like FW 800 Drives) and use FCSvr's built in Archive function after setting those up as archive devices.
That said, buying 10 external hard drives you may as well buy a VTrak.
If you want to archive to a tape based HSM via FCSvr, you're gonna spend a lot of money.
In a way, a Vtrak is cheaper in the long run.

Line-of-site @ 1200 ft

I am extending a building automation system communication bus between 2 buildings approx 1200 ft apart in line-of-site roof-to-roof. Very low bandwidth is required. I'm considering the Aironet 1300. This is in Miami, so lightning may be a problem. What components will I need for a complete system? I printed the order guide for reference.
Thanks, Dave

Consider the components necessary for your setup to permit a segment of fiber between the rooftop components and the rest of your network.
"Lightning Arrestor" is a misnomer: it won't do a thing to prevent a lightning strike or the damage / effects of a direct or near lightning hit.
Having a segment of fiber between the external stuff and the internal network *will* save you, "lightning arrestors" will not.
If you put a copper/fiber converter at the AP, then run the fiber to either another converter, or an available fiber port on an existing switch is a good way to go. At worst, you lose the AP, power supply, and probably some coax.
You still need the "lightning arrestor" for code compliance ("Entrance Protection"), just don't relay on it to save your network.
Good Luck

500k profile after disruption and new line install...

Hello,
Status:
I have an open fault logged with BT;
Phone line ok but broadband speed low, profile appears stuck at 500k.
History: sporadic BBand connection and noisy phone line followed by outright failure of both.
Engineers visited and confirmed line between street and master socket probably corroded - they put it on leg+leg to get it working while we waited for a new physical line to be installed.
Pavement was dug up, new armoured cable run from street to house, and a proper master socket fitted (NT5 ? but no inbuilt ADSL filter).
In effort to ensure low noise, ALL other sockets in the property disconnected.
Digital phone (3 handsets off a single powered base) are run off the master socket using a filter.
Router is business hub - 2700hgv; f/w 6.1.1.48.1-enh.tm , h/w 2701-100589-005 .
Hub is connected to same master socket as phone (as it's the only socket now connected to the new line).
New line was installed approx 18 days ago.
Speed tests (speedtest.net) repeatedly show download of 480kbps, upload around 620kbps.
No change since new line was installed and all but the master socket decomissioned.
I use wireless to the router but also repeated tests with a Cat6 copper RJ45 cable and got same results.
Have taken all wireless devices offline and removed electrical items near phone line power supply and cable path to reduce potential noise and repeated tests.
I left the router on for two weeks and no increase in broadband speed.
I rebooted it twice this weekend to see whether it picked up a different profile - but no change.
BT speedtester repeatedly indicates a profile of 500k (full results further down).
Last year I had speeds about 512k on a DrayTek router before switching to the 2700HGV. The change to the BT hub upped the download speed to around 1Mbps, which made a huge difference.
I know I am "a long way from the exchange" but I've had 1Mbps last year and now have a new line into my property, so not much left that I can do to improve the situation.
I'd like to know what can be done to get me at least 1Mb download again.
I have an engineer visit due tomorrow but I believe that will be purely to finish putting paving slabs back over the armoured cable that's been installed (i.e. OpenReach dig team rather than line engineers).
After those slabs are done, I expect the fault will be closed but I'll still have a 500k profile and will need to raise a new fault all over again - that fault was opened 5 weeks ago.
Results of speedtester.bt.com run just now (1pm Sun 13th March 2011):
Download speed achieved during the test was - 363 Kbps
For your connection, the acceptable range of speeds is 100-500 Kbps.

I'm getting an error message "Untrusted Connection" on my on-line bankig site which I use all the time. Now I can't access the site.

This "Untrusted Connection" is coming up when I try to access my on-line banking site which I use all the time. I also get a OpenDNS message about Phishing and I'm not sure why or what that is. The same thing is happening on my laptop which has Windows 7.

Did this and it now works.........and I was blaming firefox!!!!!

I have just uploaded my iWeb site to a FTP host and most of the site is ok however a lot of the text has gone very strange! How can i get it to publish the same as I designed it? Thanks in advance....

Please help! I have just uploaded my iweb site to a FTP Host and most of the site is ok however a lot of the text has gone wrong! Many thanks...

Maybe you could let me know which hosting service you are using so that I can add them to my list of those NOT recommended for iWeb users!
I just dealt with one today who claimed the iWeb sites were incompatible and that the first line of code should be deleted from every HTML file before upload to their server.
They didn't even offer the information that it would be a lot easier to modify the .htaccess file never mind offer to do it for a customer.
Nobody should expect to pay for service like this and the answer is to dump them and go to a company that gives you some value and support for your money. If the ones on this page don't meet your requirements for cost and service...
http://www.iwebformusicians.com/iWeb/Publish-Website.html
... search this forum for those recommended by other users. There's a long list of them.

Would you please provide some link or blog here? Thanks!

Hi Diana,
If you solved your problem then Please tell how to configure Near Line Storage Connection. currently we have SAP BW 7.3 and Database Oracle 11. Do we need to install any NLS addon/Database or any setting we need to do at Database level to enable NLS in sap bw as i read some were that we need same third party tool for this.

Trying to create and save a new site for the Bayside Beat tutorial but am having trouble

trying to create a new site as explained by David Powers in this tutorial but I am already getting hung up.
It tells me to go to site and then to New Site. I do that and type in Bayside Beat on the first line. (as soon as I do that you notice a red X on the right side of Bayside Beat.)
I'm told to Browse for my folder which is on my desktop and click ok. When I press SAVE another window pops up.
This time it tells me another site is named Getting Started and I'm asked to enter a different name.
Question, where is this other site that is named Getting Started? What name do I call it now!?
So I rename the site name San Francisco and press SAVE and another window pops up.
This time it tells me I may have further problems still...What am I suppose to do?

Do you mean, are the contents still in the original folder or was it transferred to a new folder?
Does it make a difference if it’s in the original folder?

I subscribed two weeks back and on the iTunes site Step 1 gathering data is still going on. Why is it taking so long?

I subscribed two weeks back and on the iTunes site Step 1 gathering data is still going on. Why is it taking so long?

I was also having this problem after having successfully used iTunes Match previously. The problem appears to be when there are two version of songs and one of them has the iCloud icon made using a dotted line. Here's what solved it for me:
1. Identify your duplicate files. I have a large library, so I elected to use Dupin Light (available on the Mac App store). I suppose I could have used iTunes duplicate finder too, but I prefer the flexibility of Dupin.
2. Once you have identified your duplicates, find them in iTunes. In my case Dupin identifed 50, from 19,000+ tracks, so for me it was not a large number to check manually.
3. When you find the duplicates, if one of them has the aforementioned dotted line iCloud icon, this is the one you need to delete. If you accidently delete the other version, you can always download it again if you have purchased it from iTunes. In any case, it seems to be the tracks with this icon that it is causing iTunes Match to stall, so you will need to delete all of these.
4. Once you have completed step 3, iTunes Match should not proceed and complete.

BW NLS(Near Line storage) a

Dear Gurus
We are planning to go for a POC on Near Line storage. I am looking into the online documents. If any one of you guys are already using the NLS solution, I would like to know more details about.
1. About your experience with NLS
2. Pros and Cons if any?
3. What is the compression factor you all got on the data.
4. Data model changes - like activating nav attributes is easy to implement or time taking
5. Share details about your POC, how you have tested the product.
6. Any interesting facts about NLS.
Can share any personal experience related to it.
Thank you guys in advance

E1 Link and Leased Line

Dear Professional,
My existing customer wants to use the existing leased lines as a backup and use the new 4 E1 lines (bundled) as an active links to their current VOIP network.
Any suggestion and sample config is a big help and appreciated.
Thanks in advance.

Hi,
Thanks for your reply. Currently, my customer has an existing VOIP network. They have around 22 different sites and connected via leased lines. In the main sites, they have 2 3660 routers and the 22 remote sites are distributed to these routers accordingly for load balancing. The routing protocol they are using is OSPF.
Since they requirements are increasing they decided to expands and upgrade the existing 3660 routers to 7609 router, while the existing leased lines will upgrdae to E1 links, some of the sites with low requirements will use the same links and those sites with higher demands will upgrade to E1, but the customer are insisting to keep the existing leased lines as backup and the new E1 links as the active.
Thank you and regards

How to change category on open and closed PO and Requisition lines

We realized a little late that our category definition needs change. But when we change the category definitions (including structure) how do we change the existing PO lines and Requisition lines to have the new categories? We checked for any APIs, but there are none. What other option do we have?

changing the name of the home directory and the login name is not advisable. it can be done
http://www.macworld.com/article/132693/2008/03/changeshortusername.html
but a better way would be to make a new user account using system preferences->accounts. call it whatever you want. log into that and delete the old account. since you just got this computer you don't have any data on it yet, right?
