I am unable to access intranet on my MacBook Pro 13" with OS X mavericks. Is it possible to use files on the Local Area Network?

I am unable to access intranet on my MacBook Pro 13" with OS X mavericks. Is it possible to use files on the Local Area Network? I use the files on the Local Area Network on my windows computer by typing in the I.P address in the library. Kindly guide me how i can use these files stored over the Local Area Network.

I disabled GateKeeper's automatic blocking of unrecognised developers, and so I was able to install the driver.
The Mobile Connect program is now installed, but the computer still does not recognise the modem.
I also borrowed a USB hub from a friend and it didn't make a difference.

Local Area Network Application

Please I am trying to write a local Area Network Application that would work for an organisation.
I intend using RMI to approach it. But I would want to know if RMI approach to network programming as any security issues. Cause i want the application to be super secure. I would have used socket but i kind of find it difficult to use socket to develop complex applications. I would also appreciate if any one could help me with a tutorial that explains in details on how to use socket to develop complex applications.
This is my email address *[removed by moderator]*.
Or you could give me a link were I can download it.

Well, you would use sockets to implement a complex application just as you would to implement a simple application -- only your application is going to be more complex. You wouldn't use the sockets any differently in your complex application.
To find a tutorial about how to use sockets, your web search keywords are "java socket tutorial". Choose the Oracle tutorial from the list which you get from your search engine.
As for RMI: it's implemented using sockets, as is any Java application which communicates across a network. Whether it has any security issues -- I'm no security expert, but no doubt you can use a packet sniffer to see what it's sending. And since it sends serialized Java objects, it might be possible to reverse-engineer the packet sniffer's output to inspect the contents of those objects. Whether that counts as "super secure" is up to you when you clarify the term's definition.

Login on local area network

how can we get list of users who login on local area network?

You will need to provide more detail. The question is very broad.
If (guessing here) you want to find all users in a NIS passwd map, type:
#ypcat passwd > nis_contents.out

It's s small local area network I'm looking to create.

Hi
Can some one point me in the right direction please.
I have 32 G5 machines running latest OS I'm fed up with my IT department not being able to help with the smallest of issues.
I want to be able to connect all my machines together have a shared folder system be able to get work of one machine to another create accounts for all staff and have a reasonable shard volume some place to hold backup files. Not much to ask is it.
I need a server of some sort and some way of managing the server, but which one and how big.
It’s s small local area network I’m looking to create.
Just start me off in the right direction some one please.
Or can I use one of the G5’s to manage all the machines with server software installed on it? If I can how do I join all those wires to one Mac?

Hi jegoadby,
Welcome to the forums... you are in the right place.
I suggest OSX server is what you need. An Xserve would be ideal. You could just buy the OS X Server software and run it on one of your G5's (though that Mac would need to be dedicated to the job and not used by anyone for day-to-day work).
Your strategy will depend on the current IT architecture of your organisation, and how much you need to play within that architecture, eg. DHCP, DNS, Printing services. Easiest for you woud be to create your own network of just your Mac machines & server.
To give you an idea of what this will involve check out Appendix B, 'Mac OS X Server in a Small Business' example, of the Getting Started PDF at:
http://www.apple.com/server/documentation/
Please come back with any specific questions.

IP addresses detection in a Local Area Network

hi,
In developing a Administrative tool for a network, i would like to know about the "networking concept in java" through which, i can detect the all end hosts in a local Area network. Plz provide detailed info. regarding subject and hints related to programming.

Dear ejp,Dear gaurav...
i would like to clear my query.I would like to clarify my reponse.
Actually, i want to develop a network tool that detect the all end-systems in a LAN. Actually there is no such thing as a LAN in TCP/IP.
Basically, i will use Windows bases network.So you need to take up my suggestion.
Although i tried using DOS commands but felt weak in that. Me too. Very weak at the knees.
Now, i just need to know how to detect all ip's on a windows based network.You just need to ACT ON THE SUGGESTION I ALREADY MADE.

I can no longer print to the 3 Canon printers on my local area network. The print dialog box states that the print file is accepted and the job is printing, but the files never print. Everything worked when the computer and printers were initially set up.

I can't help with the scan/print problem. You seem to have done everything I would try.
I don't know if maybe using a registry cleaner would help.

Local area network disable internet connection

Hello,
i have a strange problem, i explain
Computer A win XP ip 192.168.2.231 with onboard network card
Computer B win 98 ip 192.168.2.232 with pci network card
Router Linksys WRT54GS, with ip 192.168.2.230, but i use it just like a hub because i don't have here internet connection
both computers connected with cable and all work nice.
Then i added a wireless/USB Planet because i want to connect it to another router in another building to get internet connection, so i connected this Planet wireless/USB to computer A, all work nice, i get signal internet connection and ip 192.168.1.102
but ..... and that is the problem, when i connect computer B win local area it disable my internet connection, i try to ping some domain name from computer A, where Planet adaptor is installed, but it try to find this domain name in local area instead to route in internet connection, if i deactivate local area ..... internet connection work like a charm.
I tried to change several ip groups, all in 192.168.1.x, tried to disable, enable DHCP server in router, tried to change subnet mask, tried to use proxy, to play with router configuration...... nothing it not work.
So i think something about network onboard conflicts, so i installed a new pci card in computer A, ouffff nothing when i active local network i stop to have internet connection, i tried also to install another USB wireless adaptor and connect it via wireless with router, nothing ... when i active local network i stop to get internet connections
So the only way to get internet connection is do disable local network oufffff
any suggestions about ?
tks
Max

No i don't have wireless card in 98 computer, it have only pci network card.
Windows xp computer have on board network card, local network, and USB Planet adatptor for internet.
Forgot to say that, both compuers are connected to router1 WRT54GS, i use it just for local area network and printers
Via wileress USB Planet adaptor i want to connect to another router WRT54GS located in another building, all work nice, i get internet etc... my problem is local are, when i active it .. internet connection stop to work

Browsing for other Macs on same Local Area Network

I have two Macs both with Appletalk turned on and both connected to a local area network. The router hands out IP addresses, i.e. they are not fixed. I would like to either browse for one computer from the other or enter the NAME of the other computer and have it located. I carefully check the other computer to determine its name and enter it in the "Connect to Server" and it isn't found. I try browsing and it doesn't show anything except a applications/Library/User folders in "network" None of there are on the other computer.
I have to log onto the other computer, look up its current IP address, then enter it on the one I want to connect from.
It should be possible to locate other computers that have sharing turned on.
What do I do to make this happen either automatically or when I browse. Even Windooze can locate other windooze machines on the same network!

I imagine you've already done this, but when you copy the computer's name, you changed the spaces to dashes, right?
If this is the Computer Name as listed in "Sharing":
My Isolated Mac
When you connect to server (apple-K), you type this for the "server address":
My-Isolated-Mac
I've had this problem with the Network Browser too. Today in fact. Sometimes the "Network" item in the left column of a Finder window wil have a tiny "eject" icon beside it, and when you select Network, you get a list of everybody available. Sometimes you don't see the icon, and when you select Network, I just see three empty folders. I haven't figured out why, but when I did "Connect to Server" and typed the Bonjour name of one of the computers on the network, I connected and everything seemed to work again. Hmmm...
Good luck.

How to discover devices on my network

I want to connect to devices connected to my network but i can't find them. I have a external disk connected to a router and i can't access it.

First, whether File Sharing is on or off makes no difference.
If your router supports Bonjour (which might be called "Multicast DNS" in its settings), enable it. Otherwise you'll have to mount the shared volume manually by selecting
Go > Connect to Server
from the Finder menu bar, or pressing the key combination command-K while the Finder is active. Enter the IP address of the router. If you don't know the address, look in the Network preference pane.

Will Apple acept the app connected to it's server which is in local area network

Lots of people are doing this. Can you surf the web on your intranet? You should be able to buy then. You may need to open some ports on your intranet to allow the app store app.

Local Area Network File Sharing Help Needed Please!

Hello I've got a question. I'm trying to set up two Macs that are connected to the same router so that we can share files between each one. Is there a way to do this so that there's only ONE specific folder that each computer has access to on the other?
For instance I'd like it so that there's ONLY ONE folder on my hard drive that the other computer can access and vice versa.
Is this possible? I've read some literature on this subject and it says that when you allow sharing it makes your entire public directory accessible and that's not what I want.
Thanks in advance for your help!

Hi Paul, this is straight forward to do and have it work each time your 'client' mac starts up for a particular user.
Assumtions:
• both macs share the same subnet (Assuming the one used by the router)
• assuming you can communicate with each of them from each other .
• assuming both of these are OS 10.4 or 10.3 .. just making sure its not another ye olde os)
• assume that the MAC where you want the FOLDER (directory) placed is always going to be available. (ie doesn't fall into sleep mode)
• assuming reasonable network speed (I dont know what you client MAC will be using in its work flow - large or small files e.g.)
• assuming that you dont mind if ANYONE in your system of two macs can accesse the folder (keep it simple for now)
Steps:
(on your SERVER mac).. the "NAS server" machine.
• create the folder in your ~/public/<myshared_foldername> (anywhere would do btw or on one of the volumes in /volumes.....
•set up the priviliges using the FINDER WINDOW for the foler (+i) (get info)
(for example there is an "OWNERSHIP and PERMISSIONS" .. expand it all and it's pretty self explanatory". For simplicity here, just make it available to ALL and sundry.
• do what ever you do to put an icon and a label & comment on the folder
(on your client mac)
• assuming all network connections are cool and you have both airport and/or ethernet/and or/FW connectivity via your router....
• in the finder use +k (go to server) and put in the local name of or the IP address (to choose your fastest path) to the MAC that is your server.
• answer any prompts for user and password. If you dont care, you can have that MAc log into the SERVER mac using your normal user and passwrd as a registered user, else default to guet.
All so far very simple.
Now the tric is to have it AUTOMATIC so tha when your client mac startups and someone on that machine needs access to your SERVER (As a NAS server), it just happens.
and this is simply achived on the client machine by adding ing it into the LOGIN ITEMS for that user (and the others).
How is that done?
Simply DRAG AND DROP the desktop folder icon of the folder(s) to be shared) into the "login items" for the (system preferences/accounts/" users on the CLIENT machine. If there are multiple usres that need this then do it for all of them or have them do it.
I think you can also enable some options in the SERVER's (NAS) system preferences/"energy saver" to wake itup whould it go to sleep.. such as 'wake up for ether net access" or something.
anyway.. it gets more complex when you want to perform specific accesses and rights to the folders and the sub directories.
This is simply implementing NFS I beleive.
This will work first time and we use it all the time without the need for COTS or brand-x software.apps to make it happen.
hope that helps
