A few technical wireless questions

Hi all
can anyone tell me what the following means, what is preamble, short/long?
what is a good signal in -db ? and why is it a minus number?
what about noise? should we be looking for a minus number? is anything above 0 bad?
also what about gains, what effect does this have ?
cheers
Carl

A few "technical" iPhone questions

Believe it or not, I'm not going to complain about the price drop!
Instead, I've owned my iPhone for a couple of days now, and have a few burning questions:
1) Does the iPhone have the ability to keep nagging me that I missed a call?
2) Many times, when I make or receive a call, either I cannot hear the other end, or the other end cannot hear me. It's like mute is on, but it isn't. Has anyone else had this problem? (It not just between iPhones, either, it's happened with me calling a Verizon number).
3) Is there any way to have the contacts screen display the records my the way Outlook says to display (file as) a contact? If I have Jim Jones at Acme Computer, I'd like the contact on the iPhone to be under Acme Computer, not Jim Jones. If I have 10 people at Acme Computer in my contacts, doesn't it make sense to have them grouped together instead of spread all over the alphabet?
4) Is there any way to put some of the "nested" funtions on the main iPhone page? In other words, under PHONE, there is RECENT and VOICEMAIL. Is there a way to put those as icon on the main icon menu screen instead of having to touch, touch, touch to get to them? It sure would be nice, while driving, to just have to touch one button to get to where I want instead of having to take my eyes off the road to navigate a bunch of screens...
Thanks for your input.

No. Not at this time. I haven't had a phone that does though.

During the two months plus I've had it, this has happened a few times. I just call them back and it's fine. This did happen occasionally with my old phone as well.
3) Is there any way to have the contacts screen display the records my the way Outlook says to display (file as) a contact?

If I have 10 people at Acme Computer in my contacts, doesn't it make sense to have them grouped together instead of spread all over the alphabet?
I use Apple Address Book which has a check box to designate the contact as a business instead of an individual. The listing is then alphabetized by the business name instead. Is there anything in Outlook to do this same thing? I'm not sure what would happen with more than one listing from the same business. One way I've gotten around it in Address Book is to add multiple phone numbers under the business (or household for friends/families with more than one phone number) and then create a custom phone type for each person (ie. Jim Jones cell, Jim Jones home, etc.). One other thing to keep in mind is to use Groups. If you find that your contact list is getting too crowded, create some groups in Outlook and then sync the groups to your iPhone. You could create a group that had all your contacts from "Acme Computer".
4) Is there any way to put some of the "nested" funtions on the main iPhone page? In other words, under PHONE, there is RECENT and VOICEMAIL. Is there a way to put those as icon on the main icon menu screen instead of having to touch, touch, touch to get to them?

So far the only keys that you can change are in the iPod portion. Give it a few more days. Navigating the screens will become second nature. I have no trouble in the car.
Good luck and enjoy your new iPhone!

Is there any way to contact verizon with a detailed cell phone technical support question?

Is there any way to contact Verizon with a detailed cell phone technical support question? I prefer e-mail so as to provide details (like I am trying to provide here). I have tried in-store personnel (no help at all) and the web chat - they just want to see me more data instead of helping me with my basic problem!
I CAN NOT GET ANYONE FROM VERIZON TO GIVE ME ANY HELP NOR CAN I FIND A WAY TO FILE A COMPLAINT. AT THIS POINT I JUST WANT TO DROP MY VERIZON ACCOUNT BUT I'M SURE THAT IT WILL COST ME A SMALL FORTUNE TO GET OUT OF IT.
Here is my issue:
Chat transcript removed as required by the Verizon Wireless Terms of Service
BELOW IS A SCREEN COPY FROM REDDIT ABOUT SOMEONE WITH THE SAME PROBLEM WITH A VERIZON CELL PHONE
So last night my RAZR MAXX HD did something totally bewildering by spontaneously downloading 2.6 GB of data over the course of ~ 3 hours. Fortunately I was able to catch this problem before it ended up being really expensive, but I still exceeded my 2 GB data plan by 600MB.
The Culprits:
Reddit News Free: 160 MB foreground / 0.96 GB background
Android OS: 0 MB foreground / 1.18 GB background
Several unnamed applications: ~ 350 MB
Screenshots:
The massive data spike
Android OS data usage
Reddit News Free data usage
Weird unnamed processes
Detailed timeline:
5:12 PM: Incident begins according to VZW data usage website (2.60410 GB used). This is around the last time that I used my phone at the laundromat before getting dinner and watching Game of Thrones.
8:04 PM: 50% of data allowance used (txt msg)
8:31 PM: 75% of data allowance used (txt msg)
8:58 PM: 90% of data allowance used (txt msg)
9:13 PM: 100% of data allowance used (txt msg)
10:05 PM: Got the text messages and immediately put the phone into airplane mode
10:30 PM: Took screenshots
10:45 PM: Enabled wifi, installed Kaspersky premium. Scan returned no threats.
11:00 PM: Left phone in airplane mode, went to sleep.
The questions:
What was the root cause of this issue? Did Reddit News freak out as a result of an esoteric bug or was my phone hacked?
If this was a simple Reddit News bug, then why was the Android OS also trying to use such a massive amount of background data?
What the hell are these unnamed numeric applications? I've inspected my process history and this is the first time they have ever attempted to use data.
I'm pretty sure that I can explain this situation to Verizon and get out of having to pay additional data usage fees, but I would like to know more about the problem before I get in touch with them.

All I can think is your phone may have background downloaded an OTA update, and you'd then be prompted with something like, "As update to your Android system has been downloaded, would you like to install it now?"
I do find it very odd that the update would be 2.6GB. As a rough base, the CyanogenMod 10.1 firmware for your device is well under 200MB, so unless Verizon has a ****-ton of bloatware in the update, or it had to attempt to download multiple times for some reason, it may be a stretch.
But doing a little homework, it looks like the Verizon Razr Maxx was updated to 4.1 in late March. Maybe they're still rolling it out in waves? Have you gotten the update yet?
Edit: Aaaand I just noticed you appear to be running an AOSP-based ROM, which totally rules out a carrier update being sent out.
Edit2: If you want to live dangerously, you could try running:
#kill -9 12289
That 12289 is the PID listed in your screenshot. But don't run that without fulling understanding the kill command.
The ps command could also be of use, but probably not.

I can confirm that the phone is currently at 4.1.2 and that I wasn't prompted for an OTA update.The fact that both the Android OS and Reddit News processes were simultaneously using an extremely large amount of data is unlikely to be a coincidence...

That is very curious that the spikes happened at the same time.I'm curious. It may have put at least some of that 2.6GB somewhere. You could use a data visualizer tool to see if you can find it, which may lead to more clues.

The largest directories are:
DCIM: Normal looking photos (90,825 KB)
Android: Primarily map cache data (64,846 KB)
If it was downloading content then it did not significantly save content to storage. It's not like I have anything particularly sensitive on the phone, but the idea that it was uploading a snapshot of my data definitely makes me uncomfortable.

Yup, Digital Camera IMages and videos.Somewhere in /sdcard/Android would be my guess as to where a mysterious file would be downloaded, but if it's only 64MB, and mostly map data, I'd safely rule it out.I'm sorry, but I'm stumped here.Edit: I should mention I don't think this is malware, because unless a malicious app gained superuser access, any data it used would show under it's own apk in the data usage list, not Android OS.

Although I'm not really up to speed with the Android platform, I come from a UNIX background so I feel comfortable running commands. How do I pull up a bash terminal? Do I need to root the phone first?
permalink
parent
[–]omgmrjmako/PA, deb/Carbon 2 points 1 year ago
There's a number of terminal emulators in the Play Store that work well. You don't need a rooted phone to get to the shell as your user, but any privileged command won't execute unless you can grant it permission from the Superuser app that is installed when you root the device. So you could probably do a ps -e, but not a kill -9.

Got it. I downloaded a terminal emulator but unfortunately those processes no longer exist.Does Android keep a generic log of system level events like /var/log/syslog?
permalink

[–]omgmrjmako/PA, deb/Carbon 2 points 1 year ago
I don't think so, and I know you'd need superuser permission to read most of the files in /var/log anyway. I'm not super familiar with how Android does its logging, but I do know that the two files of interest are the logcat and dmesg.

Want to mention here that using your settings to set your data cap (set it on your billing day), then you won't go over again.Those text messages are really unhelpful, as they send out well after the data has been used. Chances are good you hit close to the 2GB mark before you received the bulk of the messages.

That's definitely not the case here; both my PC and and Android phone are free from pirated apps.

You used the data. Verizon can not see what it was sued for. However your phone can see whats apps used the data. go to settings-data usage- there will be a place that says data usage cycle. line the dates up with your cycle. then there will be a bar graph below that extend bother white bars one all the way to the left and one all the way to the right. after those are extended below that will be a list of apps, there should be one that used over 2 gb and that will show you what app used that data in her purse

A few post config questions on new setup

Hi Group,
Just a few post config questions.
First, how can I confirm my controller is in fact associating properly with an NTP server? On a typically cisco product, I could just do a 'show ntp associations' or a 'show ntp status'. I cannot see a way to confirm this on the gui or command line.
Second, on my guest network with web-auth, if one were to choose to not use https for web-auth and instead use unsecure http, would that be possible and if so where in the gui?
Thanks.

The third field is from a WLC running v7.4 not v7.2. I usually would install a 3rd party certificate, but what eles you can try is issue this command on from the CLI. It had issues working with certain code versions, but you might as well give it a try.
config network web-auth secureweb disable
Thanks,
Scott

A few technical questions

Ok, I just got my 5Gen 30 Gig today, and I had a few questions.
1) I had to update some of the names of the songs, because they wouldnt show up under the artist's name. I updated the names, the songs I fixed went back to the proper artist name. I then plugged the iPod back in, and it synched, but when I looked under the artists names to see if it had updated, it hadnt. Example, I know I have 5 songs by a certain artist, but when I look up the artist's name on the iPod, it says only 3. I'm just curious as to how to get it to do that.
2) I have it set to shuffle. Is there a way to have all songs show up, so if a song is on I don't want to listen to, but there's one that's a few songs up on the list, that I can go to that one without having to skip to the artist and going that way?
3) Is there a way to get iTunes to show a screen that shows all the songs the iPod, so I can delete one of the iPod if I choose?

1) See: Some songs don't don't show under artist on my iPod.
2) Shuffle is a random selection. There's no "list" as such to show you what will play next. If you don't like the song that's selected simply click the ff once to advance to the next song.
3) When your ipod is connected, click on "music" to see a listing of the songs on the iPod.
If you have the iPod set to automatically transfer songs, and you no longer want a copy of those songs on either the iPod or in iTunes, simply delete the songs in iTunes. Highlight the songs you no longer want then right click and select "clear", or from the edit menu select "clear". Next time you connect the iPod, the songs will be deleted from there also.
Only do this if you no longer want the songs on both the iPod and your computer.
You can also use the "only update checked songs" method in the iPod options (right click on the iPod in the source list in iTunes and select options, then select "only update checked songs"). With this preference checked, you can remove the check mark from the songs in iTunes that you no longer want on the iPod. The next time you connect the iPod, those unchecked songs will be removed from the iPod whilst still being retained in iTunes. You can check and uncheck songs as you change your mind about what songs you want to put on the iPod. Songs that have no check mark against them will be skipped over when played back in iTunes.
If you have the iPod set to manually manage your songs, and you want to delete the song from the iPod only, then select the iPod in the source list of iTunes, or click on the "music" option underneath it to show all your songs. Highlight the song(s) you no longer want on the iPod, right click and select "clear", or use the edit menu as previously mentioned.
This method only deletes the songs from the iPod, so if you no longer want the song in iTunes also, you'll need to delete it from there separately using the method above.
If you are using iTunes version 7 or later, all these settings can be found in the summary screen.

A few Technical questions, and problem with entitlements

Hello everyone,
I always hate my first post being a question, or several in this case, but I have no other option and wouldn't have found this forum if it weren't for the knowledge already spread.
Background...
Using Windows Vista and Flash CS5;
I am using a second gen ipod touch;
Made a small Ball app;
Used the following videos followed to the "T" to make a Certificate, .p12 file, and provisioning file

To the best of my knowledge everything is setup in portal the right way... and i mean: Device is added, checked udid several times and device name is same...bundle ID is correct in publishing settings...I used my NAME (was a problem for some people) for CN when doing the above... I have dragged the profile to the library in itunes and synced. I have UPDATED my iphone to the 3.whatever platform, and updated itunes to 9.X ...I have dragged everything to library and synced...i have restarted ipod and comp several times...
i have tried publishing as test, beta debugging, and adhoc...no luck with any of them.
At first, i had a "app cannot be installed because the signer is not valid" error when syncing the app through itunes...but then i dragged provision profile to ipod and I now get...
"The application "Ball" was not installed on the iPod "Wiggles" because the entitlements are not valid."
I spent all night last night trying to diagnose this problem, found very little info, someone else posted here, but it was never resolved.
I have checked again and again that the device is the right device, and i have remade my certs, provisioning profiles...p12s....exports, publications...etc....again and again.
Please help!
SECOND question: Am I not going to be able to release any apps in the iphone store because of the apple not supporting flash thing? (basically, i'm asking if i should stop learning this, altogether and just learn a different language and platform for development for iphone.

Dual-band wireless question

Hi again: I am new to this dual-band wireless stuff in TC having just replaced my AE with a new TC. I have a few questions regarding wireless setup.
1. When selecting the "Radio Mode" you are presented with options like "802.11a/n - 802.11b/g". Does this setting mean that the primary wireless will be a/n wile the guest wireless will be restricted to b/g ?
2. If you Option-click on the Radio-Mode pick list you can select multiple other settings. On of which is 802.11n (5 ghz) - 802.11a/b. Give question 1 does this restrict the main wireless to 5 ghz n only? (I highly doubt this as I can still connect to the "n network" with my iphone which only supports b/g.)
3. Under "Wireless Options" you can select a "5 ghz" network. Is this different than the option detailed in Question 2?
4. Finally, where can I find a manual for TC ?
Thanks for the help, Chris.

So is my assumption that the hyphen in the selection is the differentiation between the two networks?
Also, when I activate the "5 ghz" setting under options I actually see three networks, "Network1 (5 Ghz), Network1, and Network2 in my naming system. Does this mean that Network1 (5 Ghz) in the N only while Network1 is a standard N (with backwards compatibility to b/g)? I think this is the case as my iPhone does connect to Network1 while Network1 (5 Ghz) is not detected.
Thanks for the help, Chris.

So many wireless questions in my move to australia--HELP

I'm moving to australia and I have many questions--please forgive the length of this. First I had been waiting for the Palm Centro to move to Verizon because my Tungsten E is dying. Now that I'm moving I'm going to need to buy a cell phone in Australia--versus trying to get an unlocked one here I think. I see that they have Centro, but not with the big server Vodafone, which leads me back to the iphone. I avoided it because I don't want to pay for all the services I don't need. All I want is the PDA to link with my iBook G4 (still with Panther) easily to have all my contacts from my Tungsten E. I hear Palm may even be discontinuing the PDA's all together so I really do need to make the move. Yet the other big PDA, the blackberry doesn't sync easily with the mac from what I hear and read. Anybody have suggestions about a good solid phone/pda that I can use in Australia with my iBookG4? Can I spend just $199 here on an Iphone bring it with me, hook it up there with Vodafone and just use it as a phone/pda without any of the internet features?
Second question is related to communication when I first land in Australia to my husband in LA. I was told that I could use my ibook at any airport with Skype. Is this true? How? I have airport for our wireless SBC modem here, but Im guessing I would need some special USB unit. but is that the way to go. I was thinking to buy an international Mobal phone for $50 just to have for the first few days until I get internet set up over there and can start trying to figure out skype? I suppose I could try a phone card from a payphone but $50 seems like a small price to pay for communication in the beginning...unless there is a brilliant idea I hadn't considered (hence my writing here)
I am really clueless here. any suggestions, websites, links I should consider would be very appreciated. More than I can say since there are a million other details about this move that are taking up space in my head.
thank you in advance.

Same thing happened to me and I did a reset twice but the problem doesn't go away. It's Apple's video player that has problems. You don't want to reset it every time it happens, right? Get another video player, any player will do. I got flex player for free. Now I don't have any problems playing my videos any more.

Just some few Arch Linux questions

Hi, I am new to Arch Linux and am looking for some advice and answers.
Here are the questions:
1. Does the update command (I think its called pacman and it updates many things with one command in terminal) update the Arch Linux base, the DE that is installed, the apps that are installed and artwork on Arch Linux?
2. Is Arch Linux User friendly once installed (When I say user friendly, I mean something like Ubuntu)?
3. Does the drivers (Wireless card drivers, graphics card drivers, printer drivers and audio card drivers) come pre-installed once Arch Linux is installed like Ubuntu?
4. What is the stablility and speed of Arch Linux compared to Ubuntu?
That is all I need to know.
Cheers,
molom

pacman is the package manager for Arch. It will install single package, batches of packages, update the installed packages and several other things. Yes, one command 'pacman -Syu will update all the installed packages to the most recent available in the repositories. It will not update your artwork, ut everything else will be updated if you so desire.
molom wrote:2. Is Arch Linux User friendly once installed (When I say user friendly, I mean something like Ubuntu)?
Once you have installed the base systen, updated and then installed whatever desktop environment or window manager you want, whatever programs you want, etc., it will be as user friendly as you have made it.
molom wrote:3. Does the drivers (Wireless card drivers, graphics card drivers, printer drivers and audio card drivers) come pre-installed once Arch Linux is installed like Ubuntu?
As others have said, the install process does a fairly good job of detecting your hardware and installing the necessary modules, but it is up to you to install drivers for your nVidia / ATI video card if you want accelerated graphics. You'll have to install your printer (generally via cups, which you must also install). You'll have to install alsa and you may have to configure your sound.
molom wrote:4. What is the stablility and speed of Arch Linux compared to Ubuntu?
Arch is what you make it. You can have a rock solid stable system, or you can opt to be bleeding edge and risk the occasional package breaking.
molom wrote:So when you say 'pkgs', do you also mean the desktop environment as well. For example, I have E17 installed and I use the 'pacman -Syu' command, will it update the version of E17 on my PC to the current version of E17?
A package is a piece of software. E17 is a package, or perhaps a meta package made up of a bunch of packages. alsa is a package. gnome network-manager is a package. Anything that is installed on your system is managed and updated by pacman.
molom wrote:Is there something similar to synaptic in Arch Linux?
pacman is the Arch package manager. It does not need a gui front end, though there are a few third party front ends that have been written. I do not know if they are still active.

Then I also suggest as other have, that you avail yourself of the wiki, especially the beginner's guide which answers several of the questions you've asked.
Arch Linux is what you make of it, but you have to do the making. Heck, that's 95% of the fun!

Video with bonjour wireless question

Hi,
Question 1: When using two new macboook pros, my brother and I are trying to use video ichat av with wireless. It connects briefly(30 secs) and the first few frames of the image is fine, but then freezes or becomes very blocky. Finally the application stops the chat. The wireless router is a Linksys. Firewall allows ichat bonjour traffic, set in sys prefs on both machines. Any ideas?
Question 2: When using bonjour over wireless, does ichat av require a wireless router? Or can it work with just 2 wireless capable machines?
thank you for any help,
Tangerinebluejean

Hi TangerineBlueJean,
Re question 1
Ignore the Mac firewall preset for Bonjour as it opens the wrong protocol and misses one port.
You need to set a New setting.
Choose "Other" in the drop down.
Bonjour ports are
TCP 5298
UDP 5297, 5298, 5353
Give the setting a name and Add/Apply
These same ports need to be open in the Linksys preferably by enabling UPnP in the Administration tab rather than Port Forwarding as this will allow on one computer.
There is also no Preset in the Mac Firewall for iChat's AIM Login, A/V chats or the Jabber side.
Complete set of ports are here
http://www.ralphjohnsuk.dsl.pipex.com/page4.html at the second pic.
Re Question 2
Yes, between two wireless capable machines you can set up an Ad Hoc network (one Mac becomes the Base Station in effect) and then Bonjour will work.

Hi.
First of all I know the NSS322 is a small business solution, but I was planning to purchase it for home use as I'm a big fan of CISCO hardware and my entire network and cable equipment is made by CISCO anyway. I hope it is suitable for home use, after all... So I was going to use it as a storage/streamer for video files, photos and backup in Raid 1 configuration with 2x2TB WD Black discs, connected to a Cisco 4200 wireless router. Thus, I've got a few question, hopefully someone here would be able to help me out with them.
1.      Is it DLNA capable with wirelessly streaming content to, say, DLNA enabled devises such as TVs, BD players (PS3), etc?
2.      Does it accept 3TB drives and the 7200rpm drives? And in this regard, would a 2TB WD Black series drives be sufficient for it to operate a solid Raid 1?
3.      Could it be wirelessly shared with several computers when used with a CISCO 4200 router primarily for storing downloaded files directly to the NAS without storing it to a local PC's HDD first?
4.      Probably the most important question I’ve seen a number of pictures of NSS322 and I’m very confused as of the actual color of the side and top panels. Some pictures show it to be grey side panels, almost white. Others pictures show it to be much darker, like charcoal black. I mean since I’m not going to put it into a server shelf and use it at home - it’s rather important for the “wife’s approval” factor
Thanks in advance for any input on this!
Chris

Hi Chris,
Thanks for the feedback!
1. Is there a list of video/audio file formats that it is capable of streaming/transcoding? I assume the actual media server software is not WMP12, and then what is it? And I know you posted the link to the data sheet, but it gives me: Forbidden File or Application
Sorry about the Datasheet. Apparently it is for Cisco Partners. Here's a quote:
Twonky UPnP Media Server
• DLNA 1.5 Certified
• Real-time and background photo transcoding
• Supports UPnP and DLNA Media players such as Game Consoles (PlayStation 3, PSP, Xbox 360), Media Adapters, Mobile Devices (e.g. iPhone/iPod Touch/iPad with UPnP/DLNA Application)
• Supports formats: video (asf, flv, f1v, f4v, mp4, mpeg), audio (mp3, wave), picture (bmp, gif, jpg, png)
2. Do you think we could expect 3TB support in future firmware updates? Do you know if CISCO is planning to release them at a similar pace as say, QNAP?
I do not have any "official" word on this. I am sure that we will see official 3TB support in the near future. As I stated earlier, 3TB drives may work on the current firmware even though they are not on the approved list yet.
3. Can this NAS warn me in case of a drive failure (reallocated sectors, etc) with SMART warning that can be detected with diagnostic software on PC? I mean is it capable of detecting those warning and alarm me, or will it just wait until the drive finally dies and can not be accessed?
Absolutely! The NSS 300 series can be configured to send email alerts whenever there is an "event". It also has syslog support: "You can enable this option to save the event logs and connection logs to a remote syslog server." (From the GUI) It can also act as a syslog server if you wish so your other network devices can send their logs to the NAS for future use.
4. Here comes the deal-breaker What I meant is there are several variations of color even here at cisco.comone is really dark - http://www.cisco.com/en/US/prod/ps4159/ps9954/ps10817/ps10853/NSS322-200x160.jpgand the other image shows it rather light http://www.cisco.com/cisco/web/solutions/small_business/products/storage/nss300/images/NSS-300-hero-705x180.jpgand of course there are other websites that have it even whiter (and kinda ugly if you ask me)! http://www.newegg.com/Product/Product.aspx?Item=N82E16822124005Do you know if color changed to a darker shade with newer revisions (like shown on cisco.com)?
I see your point and I certainly understand the confusion. Your second link is the most accurate depiction of the color. The surface is metal so you could send it to any body shop for some sandblasting and a fresh new coat of paint. Warning: Sandblasting and/or painting your NAS will void the warranty!

Wireless Questions

Hello,
I'm Brandon and I'm new here, and a new Mac user.
I've just purchased a MacBook and have never used wireless internet before, so I have a few questions I'd like to have answered before my new Mac arrives.
First, I know friends have brought computers to my house and been able to use wireless internet, even though we have no router. Does this mean it is likely that this will work for me too?
Second, we have broadband internet running into the family Vaio desktop, which runs God-awful XP MCE. The installation guy told us we would only be able to run one computer at a time. However, if I purchased an Airport Express I should be able to run both my lap top and the Vaio (supposedly wireless-enabled) simultaneously right?

Welcome and congratulations.

There is probably an open wireless network nearby that they are able to connect to. You might be able to use this to connect to the internet, but this is not secure if you want to also share files and printers between your Mac and PC. You should set up your own wireless network, use password-protected encryption and stealth mode where the wireless network name is not even broadcast.
... we would only be able to run one computer at a time...
probably he means with that broadband modem, some modems feature a built-in router with ports for more than one computer. But you should be able to add your own router to the broadband modem to use multiple computers.
However, if I purchased an Airport Express I should be able to run both my lap top and the Vaio (supposedly wireless-enabled) simultaneously right?
The Express can support up to 10 simultaneous wireless computers. This wireless hub has no wired Ethernet ports, (are you sure the VAIO is wireless enabled?) The Extreme can support up to 50 clients and has 3 wired Ethernet ports just in case a visitor has an older laptop without wireless or you need a wired port for an older computer.
They both will work with Mac and PC and you should be able to set up file sharing and printer sharing.

You might need to install Bonjour for Windows on the VAIO.
http://www.apple.com/macosx/technology/bonjour.html
The MacBook also can share it's internet connection over the wifi network to a computer hooked up to its wired Ethernet port, or vice versa... so you could potentially hook up both computers to the internet right away using that built-in internet sharing feature before you get a wireless hub, which would be useful to have when you have a visitor and need more connections. I'm not sure how many wireless clients can hook to the MacBook shared network when it is using the wired Ethernet as the primary connection.

NMH405 Impressions after the first days - and a few beginners type questions

Hi All, After some research I took the plunge and acquired a new NMH405 (I really would have liked the non existing "NMH400" i.e. no drives). I removed the 500GB drive and added two new 1.5TB WD Green Caviar Drives and set it up as Raid-1 After a few error messages and waiting for a very long time while the drives resynched I manage to get it online as z-drive to my vista system.  I played around with the built-in backup tool (I like it!). I tried the builtin player after having placed some of my iTunes albums on the media hub and decided that I did not really like that option to much. I then simply moved my itunes libraries to the MediaHub and used the iTunes application on Vista as a front end. That works very nice.
I have a few questions, probably showing my limited knowledge of network attached drives.
Q1. Are there any other way to power off the device than pressing the little bottom on the NMH405 (aka my NMH415!)? When powered off I assume the only other way to power it on is via the bottom again?
Q2. I have noticed the device is offline for ages after having either recycled Windows Vista or the hub itself. Why is that? And what can I do to bring it online in a orderly fashion? There must be a way to get that ugly red crossed NAS showing as green and online as a z-drive in "My Computer" a lot faster.
Q3. I reformatted the 500GB drive that the box came with, added it to Disk enclosure box and attached the USB to the front of the NMH405, after a while it said on the front panel that it had detected the drive and asker whether I wanted to import the content.  I declined that (partly because it was empty!). Now how do I access this drive? I would like to (occasionally) use it to back up files from my Raid-1 setup (you newer know what could happen there...). How do I use this USB attached drive? Also i noticed it did not show up in "My Computer" - actually "Computer" in windows? Adding it directly to my windows system it is detected instantly?
Thanks for any pointers or answers to enhance my user experience. I am still learning here.
best regards
Solved!
Go to Solution.

Q1. Your correct, there's only one button at the front for powering on/off. There is though an option to reboot the device inside the web interface thru the configuration > system option.
Q2. It really depends on how fast your network can establish a connection, a mapped network drive is fine but I noticed that it slows down the bootup or login process when you turn on the PC. What I did was just create a shortcut on the desktop (location \\nmh410\media) which points to my mediahub and did not map the mediahub anymore to drive z.
Q3. If its a fresh 500gb drive with nothin on it yet, then you would need to create a partition on it first by connecting the external USB drive directly to the PC. Check out this article from Microsoft about partitioning. I think an external USB drive icon will not show up on the PC since the external USB drive is plugged in onto the mediahub USB port. To gain access to that external USB drive which is plugged in onto the mediahub USB port, I just create a shortcut to \\nmh410\media\device . For backup you can use the NTI backup software that came with your mediahub.
Cheers.

Few basic SRM questions .......

I recently completed the SRM training from SAP and I have few basic questions and need help. Full points will be rewarded.
These are my questions and it is based on SRM 5.0 Classic Scenario with R/3 backend
1. Invoice & confirmation transferred to R/3 via ALE ? . All other documents are transferred to R/3 via RFC?
2. Based on the configuration, if the material is available in the backend then reservation will be created. Other wise PO will be created. For text items, PR will be created.
     a. Who (purchaser) will process the PR in R/3 and how it is processed?.
     b. Who (purchaser?) will process the reservation in R/3 and how it is
         processed?. Assume no sourcing is setup in this case and No MRP run.
3. How the vendor is linked to the Material or product category in SRM?. During the vendor replication from R/3, vendor and material/prod category link is automatically maintained?
4. How the vendor is linked to a specific purchasing org/group? Is it based on the prod category assigned in the org structure for each purchasing org or purchasing group?
5. How to do delta prod category replication?
6. How to do Delta Material Replication?.
7. Contracts and vendor list:-
    In our SAP training we created these from the browser. But in the actual
    implementation how do we create this?. Is it always from the browser?
8. Direct Material and Plan driven Procurement.
   Can we use catalog items as direct material?. Just for example - > What
   about Car Batteries that is directly used in production and has the inventory
   also. But we are using electronic catalog for procuring this item. Is it possible to
   order this as direct material?
9. How to replicate Plant. How to use DNL_PLNT?. Is BBP_LOCATIONS_GET_ALL will replicate all the PLANT's and its locations from the R/3 backend?
10. In the HR system, which transaction we can view the org structure?

You can use the following three routines to download locations from the backend system and store them as business partners in SAP Enterprise Buyer.
BBP_LOCATIONS_GET_ALL
To get all the location numbers from each backend system that is connected
BBP_LOCATIONS_GET_FROM_SYSTEM
To get all the location numbers from one particular backend system
BBP_LOCATIONS_GET_SELECTED
To get selected locations
Previously, locations were not given business partner numbers in SAP Enterprise Buyer. If you are configuring an upgrade, you can use routines BBP_LOCATIONS_GET_FROM_SYSTEM and BBP_LOCATIONS_GET_SELECTED to check that the following conversions have been made:
·        Conversion of user favorites
·        Conversion of user attributes
·        Conversion of old documents
Routine BBP_LOCATIONS_GET_ALL checks these automatically.
Once you have run the routines, the location data is available in the SAP Enterprise Buyer system. Table BBP_LOCMAP contains the mapping information (in other words, which business partner number corresponds to which location in which backend system).
For more information, see SAP Note 563180 Locations for EBP 4.0 plant replication
