How to use a user over the network???

My point is, that i have a Mac on my room and let's say that i want to use my user on my mac which is in my room in another Mac which is connected to my tv. I dont think there's a way to do that, but in my opinion is why not to make it possible... login to your user from a mac to your mac...

You can screen share by enabling it in the sharing prefs.
If you just want to use the user without screen sharing, you have to do some complicated remote user thing that I couldn't figure out how to do on my Mac Mini...

How to backup Mac Lion over the network

I have a client who asked me to set up a Lion email server for 20 users. It is running open directory for the user accounts and has a wiki set up on it as well. I have been researching backup solutions for it. The server runs in a remote data center environment and it is the only mac on the network. There are other Linux and windows machines on the same network as well. I would like a backup solution for the email and open directory database that doesn't require stopping the email service (if possible), and I would like to back up over the network (if possible).
What would be the best way to back up this server considering it needs to be in service 24/7? I am open to both free and commercial solutions. Any thoughts or comments would be very much appreciated.

As the server is in a (remote) data center the first more normal approach for backing up over the network would require you to have access to a second computer in the same data center this would require additional hosting costs.
The next (network) approach would involve backing up from the server in the data center over the Internet to perhaps a machine at your own office, or another site, or a third option to use a commercial Internet based backup service.
Internet backup services include the following and I am sure plenty of others -
Mozy - http://mozy.com/
Backblaze - http://www.backblaze.com/
Carbonite - http://www.carbonite.co.uk/
Crashplan - http://www.crashplan.com/
iDrive Pro - http://www.idrive.com/index.html
Livedrive - http://www.livedrive.com/
If your backing up to your own Mac over the Internet you will need to setup a VPN link. You could in theory as one possible example, have the Mac mini in the data center also act as a VPN server so you can fully access it, then mount the volumes over AFP, then use any standard backup tool to copy that to a local volume. Retrospect would be able to do this as one example. Another way is rather than using AFP, use FTP to download everything. However unless you protect FTP behind a VPN it is these days considered very insecure.
Another approach is to use Rsync which is designed original for Unix/Linux for this exact purpose but like all Linux originated software is far from friendly. See http://www.rsync.net/resources/howto/mac_rsync.html

Share the same files to different users over the network

Hi,
I have a server running in my home network and want to share my photos accross the network. The photos have to be accessable from linux and windows clients and from different user accounts. The filesystem to share is btrfs right now. I would like to stick to it, but if this should turn out to be an issue, I will change it to s.th. else. I could use samba with a dedicated samba user or ftp, but both solutions feel hacky to me. Is there a better approach to the problem?
Thanks,
Wolfgang

Personally I'd go with an ftp server since I got that to work in the past but samba might do a decent job, too (don't know, never used it). But you can also just set up a web server to share your pics (maybe with a nice gallery web app?). The technology used itself does not matter that much.
Now, on to the important question: What about security? Do you need some kind of authentication or can you get away without any login stuff (since no bad guys can connect to your network anyway)?
FYI I used vsftp and pam as described at http://www.cyberciti.biz/tips/centos-re … users.html to get my ftp server running. You might be able to expand this to other solutions as well. I had to password protect my ftp server since I wanted to have write permission, too. For read only I might have been fine with anonymous ftp back then.

REGEXP_REPLACE: How to use a function over the found strings?

Hello,
Consider the following:
select regexp_replace('A1BBCCA2BBCC', '(A.)', '[\1]')
from dual
'[A1]BBCC[A2]BBCC'Now I try to put a function on the replaced strings:
select regexp_replace('A1BBCCA2BBCC', '(A.)', lower('[\1]'))
from dual
'[A1]BBCC[A2]BBCC'The result is the same i.e. the function lower has been executed with my reg. expression as a parameter, not the result strings. How can I execute the function passing as a parameter not the reg. expression but the strings, that have been found? (Of course, my real need is to use a custom function, not "lower").
Thanks in advance.
Best Regards,
Beroetz

I'm sure there must be a simpler way, but this is my first thought... (although strictly speaking in this example I could get rid of the lower function and just include 'a' hardcoded.)

Sending Connection Object over the Network using RMI

Hi,
How can a Connection object be sent over the network and run on another JVM. I need to hold connection object to execute processes one after other, that require Oracle connection without ever connecting again. I do not have J2EE container or webserver setup to hold connection/connectionpool,but need to run the process on command line. I am using RMI infrastructure to pass parameters/return values but connection object is not serializable and connot be marshalled and failing. Please explain, if there is another way using JDK 1.4
Sudheer

I think that what you want to do is connect to the database on the RMI server object, then use the server object from your remote clients to execute the processes you require to rrun.

How to i provide help to another imac user over the computer

How to i provide onscreen help to another imac user over the computer?

Hi,
If you both have iChat or Messages you can use it's Screen Sharing abilities.
You can do this AIM to AIM (Screen Names that are valid with the AIM service which includes some Apple Issued Apple ID names - although this can be version dependent)
You can also do it Jabber ID to Jabber ID.
Jabber IDs include Google Mail IDs set up for Google talk and Facebook Accounts with Chat Enabled.
Check you can Video chat with the person as it takes a similar amount of Bandwidth (the bit of the Internet Speed you computer gets).
You needs to Enable Screen Sharing in the Video Menu of iChat or the Messages app in Mountain Lion.
Highlight the Buddy in the Buddy list and use the icon at the bottom of the Buddy list (It will offer your to them or them to you)
You can also use the Buddies menu when a Buddy is highlighted.
It is also possible to "switch" to Screen Sharing in a Video chat.
In reality it instantly closes the Video chat and Starts the Screen Share.
It does not have the ability to "Switch" back as closing the Screen Share close the connection.
Screen Sharing includes a Audio Chat alongside (Technically it is an Audio Chat with an Apple Remote Desktop type VNC connection. The Apple Remote Desktop engine provides the "Desktop" "Pics").
To do this VNC part you router will need to be using UPnP (Or Port Mapping Protocol in Apple Base Stations)
AS Video chats and Audio chats use the same ports to connect it means that if you can Video your can Screen Share

I currently have a D-Link DI-604 broadband router with windows computers. How can I add wifi to the network for use with ipad? Can I use AirPort Express?

I currently have a D-Link DI-604 broadband router with windows computers. How can I add wifi to the network for use with ipad? Can I use AirPort Express?

Yes. You can directly connect an 802.11n AirPort Express Base Station (AXn) using an Ethernet cable. The AXn would then just need to be configured as a bridge to allow the D-Link to continue to provide both NAT & DHCP services for all network clients connected to either router.
In this configuration, the AXn would broadcast a wireless network for your wireless network clients to connect to.

Streaming audio file over the network w JMF. How to know when the file end

Hi
I am streaming audio file over the network using JMF. I want to be able to know when a file end so I can close the streaming session.
Can some one please help
Thanks

If you put a ControllerListener on the Processor that's associated with generating the RTP stream, it'll generate an "EndOfMedia" event when the end of the file is reached.

A tech company just set up a wifi network in my house and does not use my existing TC; how do I get it in the network to serve as backup for my iMac? (I don't need it as a wifi access point anymore)

Just bridge the TC and plug it by ethernet into the main router.
Bridge in v5 airport utility.
In v6 it is under network.. change it from DHCP and NAT to Off bridge mode.
Turn off the wireless.

Modifying JAR file using java.util.jar package over the network

Hello,
I am modifying a JAR file programmatically using java.util.jar package. The time taken to save the contents to a local disk is very less (around 1 sec) . When I tried modifying the JAR from a remote machine over the network (from mapped drive or shared folder of WIN NT), the time taken to save is 15-20 times more.
I am recreating the whole JAR while modifying. Is there any way to improve the performance. Or is it possible to write only the changed files?
Thanks,
Prasad Y S.

When you "update" a jar file, you must always recreate it from scratch.

Hello, I had the same problem. Here is a smaller version to find the Group of the current User.
The VI get the members of a Group and match it with the Username.
Note :
If the User belongs to multiple Groups the the VI returns only the 1st Groupname
If the User belongs to no Group then the VI returns "unknown Group"

Okay, here's the it copied out.

setMediaLocator: rtp://127.0.0.1:2000/audioAs I said, it just kinda stops there, what it should be doing is opening the MediaPlayer.
"MediaPlayerFrame" and "setMediaLocator: rtp://127.0.0.1:2000/audio" are just print outs I used to track here the code is getting to.

HP Laserjet M1132 MFP is too slow over the network!

Hi,
My HP Laserjet M1132 MFP is too slow over the network!
I have connect the printer to a windows XP 32bit SP3 using UBS port. The printer works fine on the local computer but when sharing it over the network it works too slow, for example with print test page it takes about 45 seconds to print and for other documents it takes much longer time.
I have installed the latest driver form HP website and upgrade the firmware it the latest version.
It happens on other Windows XP machines as well.
I connected the printer to my laptop (Windows 7 64bit) and it works fine (No delays over the network) and it seems that this problem have some relations with the windows XP Driver.
I have used local port trick on remote machines (instead of regular method) like this:
''add a local printer;
'new port'
'localport'
\\XPcomputer\HPPrinterName as port name
but still nothing!
There is nothing wrong with the network, we use to use a Samsung printer on the same machines over the network with no problem.
I Really appreciate your HELP!
This question was solved.

BEHZAD_T, how is the printer connected to the network (wireless or Ethernet)? If it is slow wirelessly, I would suggest trying to connect the printer to your router with the Ethernet cord and install it to the networked computer that way.
Another question is, relatively speaking, how close to your router are the Samsung printer and the HP printer? Depending on the distance (and what stands between the devices) there can be a lag between sending a print job and it being received by the printer.
Let me know!
