Wide area coverage

Morning All,
I have a client that needs the coverage of a very big warehouse, and i have no idea if im suggesting the right solution.
In this project i set 1 AP for each 250 square meters, but I have few bigger areas where I need a better solution, otherwise the number of APs will be too high, for example:
Coverage   area (m²)
average   AP area (m²)
Total   Aps
29707,07
250
119
7777,28

Someone told me i should use mesh, but i've not found proper documentation for this feature, because they say i should use 1 AP for every 600 sq feet, which in my opnion is way too wide, isnt it???
Thanks and Regards
Lucas

You need to really have it surveyed to see how much an ap can cover. You don't want to throw a mesh AP because it can cover more area! You still need to to match your client tx power with the ap tx power. If those numbers are working for you, then you just have to go with that or else survey the full area or a partial area so you have an idea of what coverage you get from the AP.

CUPS queues don't work with Wide Area Bonjour

I'm completely flummoxed!
My school board is installing new switches in all our schools, and moving from a single flat VLAN to multiple - one for printers, one for server, one for client workstations. Printing queues advertised with Bonjour worked fine on the old network, but multiple VLANs breaks all that since Bonjour is in the unrouteable multicast range (which makes sense, since it's not meant to work outside of the local network). I have old Tiger servers at the schools, running on hardware that doesn't do VLANs (old G4 towers), so advertising queues with Bonjour using the school server can't get me by.
I've set up BIND (DNS) to show my CUPS IPP print queues from a central Lion workstation (elemprtsrv01.example.com) in the school's subnet (10.159.40.0/22; academic-wrd.scd.example.com) as follows (my domain substituted with example.com for anonymity) - the relevant section snipped from the rest of the zone file:
$ORIGIN academic-wrd.scd.example.com.

If I use Bonjour Browser on the print server network and on the school's academic-wrd.scd.example.com subnet, I see identical info to that provided by my DNS records - in other words, Wide Area Bonjour (WAB) appears to be working and providing the necessary details.
When I try to add a printer on a school workstation, the WAB printer appears...though the PPD ("(EXAMPLE-22STUD-XeroxWC5775)" should match SCD234Q.ppd from the server queue) doesn't get imported from the server and I get a Generic Printer Description instead. When I try to print on the client, I see promising notes about connecting to the print server, but then it always pauses the queue. Here's the relevant section from /etc/cups/ppd/SCD234Q.ppd:
*Manufacturer: "Xerox"
*ModelName: "Xerox WorkCentre 5775"
*ShortNickName: "Xerox WorkCentre 5775"
*NickName: "Xerox WorkCentre 5755, EXAMPLE Student 2.2"
*PCFileName: "XRWC5775EXAMPLESTUD22.PPD"
*Product: "(EXAMPLE-22STUD-XeroxWC5775)"
*PSVersion: "(3010.106) 3000"
In the CUPS error log, I get this annoying encryption error, which no else appears to have had, according to the usual search engines:

OK, so here's the annoying bit: if I manually configure the queue on a Snow Leopard (or higher) client by going into System Preferences, adding an IP printer with IPP protocol (elemprtsrv01.example.com, queue name /printers/SCD234Q) then it works. With Leopard or Tiger, the PPD doesn't load from the server, and the generic PPD is substituted automatically.
If I manually add "ServerName elemprtsrv01.example.com" to /etc/cups/client.conf on the client machine, then it shows all the server queues and magically works too - even on Leopard and Tiger.
The problem is that I DON'T want to have all the server queues appearing on every workstation, since it'll cause mahem when the students discover all the queues and print to other schools for kicks. WAB was supposed to solve that for me by advertising only the queues that were meant to be accessed by that subnet (they'd all be there on the server, but only a real techie would know how to access them, since they weren't advertised).
Why don't the WAB queues work? Why do I get an encryption error with them?
How do I get the server's PPD to download automatically to the client? (this is especially useful for printers with customized PPDs set up with the proper settings for that printer...and for the Xerox copiers that are using accounting codes present in the server's PPD)
Any help would be very much appreciated!

Figured it out...stick with Lion (Client or Server) and use the web interface to add printers and customize the /etc/cups.conf file. If you use either System Preferences or the Print config in Server Admin on earlier versions of Mac OS X Server, you'll bugger up your cups.conf file (top part of which is reproduced here):
ServerAlias *

SystemGroupAuthKey system.print.admin

The key is to allow anything as a server name (ServerAlias *) and Allow All for / and /printers (though / by itself should be enough). If you want to listen for LPR (port 515) then I think it needs to be listed in BrowseLocalProtocols - it's not a valid option for BrowseRemoteProtocols.
On the Wide Area Bonjour front, I created TWO different entries for each printer in my domain, because otherwise the queues would appear and instantly disappear in the Tiger browser - Tiger only shows the LPR queue. The queue name is preceded by "printers/" in the IPP queue, but not with the LPR queue. Here's an example from the top of my BIND student zone file:
$ORIGIN academic-wrd.scd.example.com.

Note that the second queue is commented-out in the student zone file because it's the office queue and I didn't want it to appear in student workstation queue browsers. I customized the PPDs for these printers and thus changed the "product=" part of the TXT record to match the name in the altered PPD's "*PRODUCT:" line so that it wouldn't match with an already-installed PPD.
The above zone file generates two different queues (IPP and LPR) for each printer on Leopard and higher queue browsers, but only one queue (LPR) on Tiger. We're still supporting Tiger and even the odd Mac OS 9 client (no browsing, but they can do a manual LPR queue). Windows does both or you can manually add the IPP queue (add a new network printer using the URL "http://elemprtsrv01.example.com:631/printers/SCD234Q" and make sure you're using the PostScript driver for the printer, or you'll get garbage). iOS devices browse for _universal._sub._ipp._tcp records and you need to add the URF= field in the TXT record or the queue won't show up...and add a file /usr/share/cups/mime/airprint.types with the single line "image/urf urf (0,UNIRAST<00>)".
All my users from Mac OS 9 to Mac OS X to Windows can now print using a central print server that magically shows up in the print browser...yay!

Setting Total Area Coverage (TAC or Density) in InDesign

Is there a way to set the Total Area Coverage (TAC or Density) in the Export options from InDesign?
I feel that the color management tools relate to elements created within InDesign and not placed images.
My printer requires a PDF/X-1a:2001 compliant PDF with a TAC of 240% maximum.
Is this possible using from within InDesign, or do I have to address 'Placed' images within Photoshop or Illustrator?
Thank you for your response, in advance.

InDesign's colour management can be set to affect placed content as well as native content.
Do you have (or can your printer provide, or suggest) a CMYK profile that has 240% TAC?

How to use wide-area Bonjour?

My understanding of Wide-Area Bonjour is that I can access Bonjour services while outside the local network. So for example while at the office I would think I could access the iPhoto library of a computer at home, at least that's what it seems to me.
Am I right? If so, how is this used? I can find no instructions.

I'm interested in this as well; documentation is minimal. Please post back here if you learn anything...
I was hoping to see support for DynDNS or similar, but no...

Total Area Coverage below 200?

Is there anyway to change the total area coverage to be below 200% in the output preview window?
We recently changed newspaper stock and I need to be able to see ink density warnings for 165% or higher. 200% seems to be all that Acrobat allows- Any way to alter this?

Utilizing Cisco WAAS (Wide area application server) to optimize CAD traffic

Hi all,
Has anyone used Cisco WAAS (Wide Area Application Server) to optimize CAD traffic for agents sitting at remote site ? if so, does the remote agent really notice any improvement login to CAD or while working in CAD ?
Thanks in advance for any inputs / suggestions !!!
D.

Hi,
The push-down, the WAAS will push down the signed SMB traffic to Generic AO.
Be aware that if you turn on SMB signing the optimzations performed will only be TFO/DRE/LZ. The signed SMB/SMBv2traffic is optimized, not accelerated with SMB AO like unsigned SMB/SMBv2 traffic.
We know this is confusing, whence: CSCub42695.
I hope answers at least some of your questions.

Abhishek

Leopard Wide-Area Bonjour DNS Issue

Hi, all. Got an issue with Leopard's domain name resolver. A while back, I was experimenting with the "use dynamic global hostname" panel in Sharing. I wasn't able to get it to do anything useful (and I don't want help with that; I know what went wrong, and how to fix it, but haven't gotten to do so yet), but here's the thing - after returning the settings to the defaults (unchecking the "use dynamic global hostname" box), it seems to have left something behind in my system configuration.
In particular, when I run "scutil --dns", I see the following two entries in addition to my normal DNS server and the "local" Bonjour resolver (domain names censored):
resolver #3
domain : bonjour.mydomain.com.
options : pdns
timeout : 5
order : 150000
resolver #4
domain : mydomain.com.
options : pdns
timeout : 5
order : 150200
The type of these is "pdns" - "private DNS", or wide-area Bonjour. They look harmless - but the fact that they're there is somehow preventing my machine from being able to resolve any hostname in "mydomain.com" that is a CNAME.
I can get rid of them temporarily by running scutil and removing the key "State:/Network/PrivateDNS" from the database... and then name resolution works normally again. But a reboot, or a change in Bonjour settings (such as enabling or disabling "Back to My Mac"), causes them to come back. I can't figure out how to purge them from the actual system configuration database. Any suggestions?

Here's the fix. Open Keychain Utility in the Utilities folder and choose "System" in the Keychains list in the sidebar. Now you'll probably see two entries of type "DNS Key" with the names "bonjour.mydomain.com" and "mydomain.com". Just delete those Keychain items and you should be back to normal.

Wide area bonjour for mac

I know this is not an exclusive forum for "bonjour for macbook" but I could not find any category explicitly catering issues with this so I thought this could be the place to ask my query.
So here is my problem.
To enable wide area bonjour on my laptops I have configured my own local dns sever by following details on this document http://www.dns-sd.org/ServerSetup.html and then configured my clients i.e. laptops by following http://www.dns-sd.org/ClientSetup.html page.

I'm trying to do the same thing and found a couple helpful threads and links.
http://blog.inig-services.com/wp-content/uploads/2010/03/WAB.pdf
http://discussions.apple.com/message.jspa?messageID=5959986
Unfortunately, following the above PDF guide, one key step fails. After enabling bonjour registrations using the serveradmin settings command and restarting DNS, I can see that the dnsextd proxy fails to start:
dnsextd starting
main: setrlimit - Invalid argument
Using default file descriptor resource limit
startedvialaunchd
ConnectToServer: connect - Socket is not connected
ConnectToServer: retrying connection
I verified via netstat -na that BIND is listening on 5030 and I can use nslookup to run queries against it. There appears to be no good reason why dnsextd can't connect to it @ 127.0.0.1#5030 as far as I can tell.
Is this feature broken in the latest Snow Leopard Server 10.6 release?

Wide-Area Bonjour / Dynamic Global Hostname

Hello everyone
I have a very specific problem, My AEBS is not sending UPDATE requests to my own DNS server when my DSL IP address changes over time.
I have my own DNS server and run a dynamic zone with TSIG aututhentication.
If I configure the "Dynamic global hostname" on my Macs behind my AEBS acting as a NAT gateway, they will register themselves withe the correctly natted address.
In fact, this is amazing and works very well:
sftp-ssh.tcp.dyn.secret.domain domain name pointer MacPro.sftp-ssh.tcp.dyn.secret.domain.
smb.tcp.dyn.secret.domain domain name pointer MacPro.smb.tcp.dyn.secret.domain.
ssh.tcp.dyn.secret.domain domain name pointer MacPro.ssh.tcp.dyn.secret.domain.
macpro.dyn.secret.domain has address xx.yy.169.96
But my AEBS itelf has an older address:
airport.tcp.dyn.secret.domain domain name pointer Airport.airport.tcp.dyn.secret.domain.
smb.tcp.dyn.secret.domain domain name pointer Airport.smb.tcp.dyn.secret.domain.
airport.dyn.secret.domain has address xx.yy.177.175
I can force the update by restarting my AEBS, but this is not a good workaround.
Has anyone else experience running a wide-area bonjour DNS server?
Thanks

Hi Patrick,
I suggest you bring this up on the bonjour-dev[1] mailing list. You're much more likely to reach people with the right knowledge there.

Wide area bonjour - windows dns

Hi,
I have been trying to setup wide area bonjour using ms dns server for serveral days and come up against a dead end. In most examples on the internet BIND is used as the DNS server and all configuration is shown for BIND (except one PDF "www.grouplogic.com/Knowledge/PDFUpload/.../WanBonjour_1.pdf" which has examples for MS dns but it doesnt work).
So I have managed to configure the MS dns server as far as advertising available services but when I try to resolve a service it fails. I think its a problem with the srv record but have tried so many different configurations for this record I have lost count. config below.
Has any one set this up? could really do with a good example of it working on windows dns.

thanks for the quick reply AndrewTJ - I did notice the typo after posting and corrected however the problems remains. below is the contents of my up.com.dns file - i can see nothing out of place but cannot get a resolution

How to setup Wide Area Bonjour across multiple Subnets?

Hi Gents,
It's been painful trying to get this up and i feel i am almost there, but can seem to complete the last bit
I have this network i am helping to manage
OS X Lion Server running
     DNS
     RADIUS
     Open Directory
So the wifi network is in a seperate subsnet from the LAN on which the Mac Server is connected to which posses the problem of Bonjour not routed between the two subnets. So i decided to enable Wide-Area bonjour browsing and create a Service record for afp share folders. So i have got to the point where it's coming up on devices on the seperate subnet under the network icon, however when i try to connect to the service it just says connection failed. Authentication is occuring because if i use wrong credentials it doesn't attempt to connect.
I believe it might be the way i am defining TXT. I have little experience here, any assistance would be appreciated
This is the configruation in DNS Settings on Server Admin
Service Name: Work\03****\03\you
Service Type: _afpovertcp._tcp.
Host: work.damnyou.org.
Port: 548
Priority: 1
Weigth: 0
TXT: "path=PUBLIC/"
Anytime i attempt to connect, it just says Connection Failed
Thanks,
DeeBeeMac

DeeBeeMac,
Did you get things working good for you? I also have a wired VLAN and a WiFi VLAN that I have a implementation with Aruba network for my WiFi, they have an option called airgroup and printers seem to come and go.   I really don't want to use the Aerohive solution, so I was thinking of a Mac mini with an interface on both VLANS.   Do you need to setup anything to get os x to announce services it see's on both networks?   I also tried avahi and turned on reflector, however it seems spotty as well.

How to conect client with server in wide area network

hi,
this is yasmin riaz..i have installed oracle 8.1.5 enterprise edition on my server and then install oracle 8.1.5 cleint on another pc and then i get connected from client to that server db by net8 asistant on client machine..this setup is working fine at my office means connecting to server via client in local area net work..
now i want to connect to this oracle server from my home client machine which is now on wide area network..i dont know how to connect now from client machine at my home to server machine at my office..
can anyone suggest me how to do this conectivity..
its urgent
thanx in advance
yasmin riaz

while you are connected to the same domain as of oracle server then this is no problem.
varify your domain connection by pinging
the oracle server machine at your office,
ask your network administrator to allow you
enough priveleges and network infrastructure
so that you could see oracle server in
your network neighborhood.
now create your net connect string
and verify it by looking into tnsnames.ora
now try the connection
if the entry of oracle server exists
but it does not connects then
replace the name of oracle server machine
with tcp/ip address of oracle server in
tnsnames.ora

Clustering EJB's Across a Wide-Area-Network

Hi Eric,
          If you have a highly reliable database access or replication strategy, I
          feel it is better to rely on that for failover across sites. IMHO.

Wide Area Bonjour and making it *NOT* use a NAT

Does anyone know if there's a way to stop Wide Area Bonjour from using the NAT gateway when it detects it's on a private network? This seems to be the default behavior and I wondered if it was possible to disable it.

Well for what it's worth, I moved my network onto 192.0.2.X which is a section of IP addresses reserved for testing - so while not strictly private (though they never appear on the Internet) it means that Bonjour doesnt try to use the NAT.
Can we say hack?
