Terabyte IFW over network

I can copy and paste 20GB files from Windows 7 to Windows 10 over my homegroup.
But if I use terabyte IFW on Windows 7, creating file on Windows 10, it hangs after 300-600 MB.
I'm running most current version 2.93

Im trying ot transfer webcam lifestream over the internet to a specific user.
It works in my home network but does not over the internet
What Im doing is:
create the processor using ContentDescriptor.RAW_RTP
create the transmitter using the user IP
localAddr = new SessionAddress( InetAddress.getLocalHost(),
portNumber ) ;
destAddr = new SessionAddress( ipAddr, portNumber );
rtpManagers.initialize( localAddr );
rtpManagers[i].addTarget( destAddr );
Thx for any help

Running a java program over network

Hi,
How a java program on a machine can be run without having JRE on the same machine, rather interpreting bytecode over network having JRE on another machine?

Rahul.Kumar wrote:
well, so my java program is running on x. Initialy X had JRE and on invoking java program from command prompt, it had looked for JRE at path, set in environmental settings. Now I moved JRE to another machine Y and connected these two machines (X and Y). You have two machines X and Y.
"Connected" or not has nothing to do with this discussion.
In X path is set to the JRE on Y. The path on X has absolutely nothing to do with anything on Y.
Now execute java program on X, theoretically it should work or what is wrong with this?This makes no sense. Presuming you meant Y in the above then the following must be true.
1. You must have a JRE on Y.
2. You must have a java application on Y (or one accessible via the file system on Y.)
3. You must be on Y and start the JRE passing the java application that is on Y to it.
Notice in the above there is no mention of X. There can be no mention of X.

Help! Saving an image to stream and recreating it on client over network

Hi,
I have an application that uses JDK 1.1.8. I am trying to capture the UI screens of this application over network to a client (another Java app running on a PC). The client uses JDK 1.3.0. As AWT image is not serializable, I got code that converts UI screens to int[] and persist to client socket as objectoutputstream.writeObject and read the data on client side using ObjectInputStream.readObject() api. Then I am converting the int[] to an Image. Then saving the image as JPEG file using JPEG encoder codec of JDK 1.3.0.
I found the image in black and white even though the UI screens are in color. I have the code below. I am sure JPEG encoder part is not doing that. I am missing something when recreating an image. Could be colormodel or the way I create an image on the client side. I am testing this code on a Win XP box with both server and client running on the same machine. In real scenario, the UI runs on an embedded system with pSOS with pretty limited flash space. I am giving below my code.
I appreciate any help or pointers.
Thanks

While testing more, I found that the client side is generating color UI screens if I use JDK 1.3 JVM for running the server (i.e the side that generates the img) without changing single line of code. But if I use JDK 1.1.8 JVM for the server, the client side is generating black and white versions (aka gray toned) of UI screens. So I added code to save int array that I got from PixelGrabber to a text file with 8 ints for each line in hex format. Generated these files on server side with JVM 1.1.8 and JVM 1.3. What I found is that the 1.1.8 pixel grabber is setting R,G,B components to same value where as 1.3 version is setting them to different values thus resulting in colored UI screens. I don't know why.

Accessing shared files over network

I am having some problems with a couple of database files that I access with a Java program over network. Different computers running this program all need access to these files, and my question is if anyone know of a good way to make sure that only one user have access to these files at the time. There is no server software running were the files are stored, they are simply reached through file sharing. Currently I am creating a lock file indicating that someone is editing the files, however if I am unlucky 2 users create that lockfile at the same time and then both get access to the file corrupting it. Anyone experienced this and know of a nice solution to avoid it?

Share Aperture photos over network

Hallo every body,
iam searching for a solution, how to share photo over network for a long time, in our company we have 40 macs(imac, mac bookpro) and 3 xserve, vtrak and 30pc. and we have round about 30000 pic they are saved in iphoto library on one of the xserve.
My Boss wants from me to find a solution to share these photos over network. the mac users must use iphoto to access these photos.
which program shall i install on the server so that the client users can access the photos from there macs through iphoto.
at the beginning i used the share library option in iphoto, until iphoto 9.1.1. By iphoto 9.1.1 on the client when i click on the shared library my searching field disappears and i cant search in the shared photos.
I thought Aperture is the solution, so i shared the aperture library over the network (with afp protocoll) but in order to access the network aperture library, first i need to install aperture on the client and then i open iphoto and from iphoto option i can choose the option access aperture library.
how can i solve it without to install aperture on the client, is there any iphoto plugin so that i can access aperture library without installing aperture
or is there somebody uses another solution???
please help
best regards
Tony

Neither iPhoto nor Aperture is the solution for this.
The idea of using iphoto on the client machines is wrong, it's just not designed for that use. Iphoto is designed for a family with a point and shoot camera, or even a phone. Aperture is a pro level photomanager. Installing Aperture on all the mchines means you will have to purchase the app for all the machine, you need a site licence.
Also, it won't work anyway. You can't share an Aperture Library like an iPhoto one an only one user can access the Library at a time. So, one of the users acesses the Library and all the others are locked out.
Neither are what you need: you need a media server application. A pro level media server. Tell your boss he's fooling himself if he thinks anything else will work reliably.

Install Solaris10 over network.

I have one sinfire v245 box which is in remote location (DR site). I want to install Solari10-u5 on it.
I can't travel to remote site due to some restriction.
Presently Solaris10-U1 is installed in the box.
I have telnet/SSH access to Solaris-OS, and i have SSH access to it's "Advanced Lights Out Manager".
There is no one in remote location who can insert Solaris10-u5 media.
In this situation, is there anyway that i can freshly install Solaris10-u5 on it ?

Ok. I learned the way how to install Solaris over network.
I have created a install server on another solaris box, the client and this box are in the same network.
I am trying to install the client, i am getting this error on the client continuously . Any idea how to solve this ?

Expdp over network fails.

I have a test1 and test2 db's on two different servers. I want to run expdp from test2 db and get the export of a table from test1. I have created a db link and used network_link in expdp command. Granted read,write on directory to user with which i am connecting to db.
Using expdp over a network_link fails with this error. For the same user I have tried it locally on test2 db and it works fine.
Is there any other step to be done ?
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-39087: directory name DUMPS is invalid

expdp un/pwd*@test1db* job_name=EXP_test1 directory=dumps network_link=test1.dummy.COM dumpfile=dp.dmp log
file=dp.LOG tables=a.tableThis is the problem. When running export using NETWORK_LINK to test1, you need to connect to test2 not test1.
The idea is your connect to test2 first , test2 then connect to test1 using database link and bring the data over network and dump to local directory.
In your command it's actually running export against test1, then in that case, test1 need to have directory called dumps defined.

Impdp over network: sometimes slow

Hello,
I've just made an experience, that impdp over network is sometimes slow and sometimes fast:
My configuration:
I have a "source" database (lets say A), with version 11.2.0.1, and two "destination" databases B (11.2.0.1) and C (11.2.0.3).
The data size is about 100 GB. Import from A into B needes about 4.5 hours, and import from A into C takes about 1.5 hours.
The data which is moved are identical. I've also checked the wait states, and we have found out, that database B makes a lot of log switches
during import, which is the reason, why database B is such slow. On database C there are almost no log switches.
B has log switches frequency about one in 2 seconds. C has aprox. 6 log switches in the first 30 minutes (during DATA load).
That database B has logswitches, and C not let me think about Direct Load versus External Table Load, which is described in the documentation.
But this seems different when using network_link: the trace of the DW process does not support this information (but should, as described in 552424.1).
I think, there are some bugs/features fixed/changed between 11.2.0.1 and 11.2.0.3 regarding load strategy over network_link.
There might be also a chance, that a initial parameter is different between B and C causing to different behavior, but
Does anyone have a similar observation? Does anyone know about this "change"?
Additionals:
The users have all the same grants, the data are exact equal (by FLASHBACK_TIME), remap_schema and remap_tablespace are used at both.
Ulrich

Hello,
Database A is in archive mode, B and C not.
The problem is in the data transfer, not at index generation.
For C, the data transfer is 30 min, Index generation is about 1h.
For B, the data transfer is about 200 min, Index generation in about 1h.
I have one new information: We have switched back after this to dumpfile transfer, and interesting: With dumpfile, the import is done with Direct Path.

Cant open over network from Windows to Leopard, but ok to Tiger

Hi
We have a number of Mac Pro's some running Tiger and others running Leopard. I can open any quicktime file over our network from a PC to any Tiger Mac, but not to a Leopard Mac. Why not? I can see the files I can open any other file type, just not QT. Copy the same file over to one of the Tiger Mac's and I can open it from the Windows PC. This would not be such an issue, but we are dealing with 1920x1080 uncompressed files and it is a real pain to move them.
Get Error 43: a file could not be found
Any suggestions would be appreciated.
Cheers
Tony

Well outside help other than this list has solved this. Seems there is a bug in QT windows that if a QT file resides in a folder on the MAc with a name longer than 8 characters, it wont open over the network.
ie. Running QT Windows 7.5 connecting over network to a Mac running leopard.

Playing footage over network - slow down after a while

Hi everybody, I have ProRes422 footage I work with stored on network. We bought a 12TB NAS and I found, that when I play the edited movie from timeline, it freezes after a while (2-5 minutes) - it seems to me there is some kind of network overload so that the data cannot be transferred fast enough to continue playback. I thought it is problem of the NAS, but I tried to read the footage from external HDD over network and the problem is the same. Would any of you have an idea how to fix this?
Thanks

For users like you who insist on ignoring the warnings and still want to buy cheap, I offer this alternative:
Buy Local Attached Storage, RAID 5, for each work station, a gigabit Ethernet switch, and CAT6 Ethernet cabling.
These days, you can buy 8TB of RAID 5 storage, including the RAID card, for less than $4,000US. The Ethernet6 switch is about $50US and the cabling is cheap.
Buy twice the storage as you think you need, then make file copies via the gigabit Ethernet network of all files on the storage on each computer onto the storage on the other computer. Now, you are maintaining a continuous back up of all data, which is a bonus benefit.
The real benefit, though, is speed. Modern RAID 5 storage systems achieve throughput in excess of 600 MB/sec, far more than 23 MB/sec.
Your investment in new equipment will be far less than buying a SAN.

Files deleted over network

Hi, some of users over the network accidentally deleted a folder from XServe, and he asked if it can be recovered, when someone deletes a file/folder over network OSX reports that "the item will be deleted immediately", is this true? it wont going to be stored in some "Network Trash Folder"? or ".Trashes"? or "Temporary Items"??
And if it really wont be recovered, is there a way to prevent this in the future? like to tell OSX Server to put all the files/folders deleted over network to be stored in a special folder for a certain time to prevent loosing important files accidentally or by other users??
Thanks

Bertrand> This seems a nice idea, but its not exactly what i need, people still need to delete files from the server, but sometimes they delete important things and im looking for a way that the OSX Server keeps the remotely deleted file for a certain amount of time so it can be restored if needed. many times users accidentally delete files from the server and hit the "OK" button without noticing they just delete an important file from the server and not from there HD, for example, in Apple Share IP on OS9 if you delete a file over the network it would keep it in the user Trash and he empties it, and if he for example restarted his computer, the file on the ASIP would be stored in "Network Trash Folder".. why the mighty OSX Server doest have this great ability?!
Steve> Tapes is great for backup and archiving, but its not what i am really looking for, it has the same problem i have with Time Machine, time machine wont backup a file copied to the server and accidentally deleted within an hour, so Tapes, wont backup a file copied and deleted within a day..
WelshDog2> just a question: if i dont have any partition on my XRAID, how can i make it backup its self on its own HD's?! is this possible?! it wont solve my problem but its good to know if this can be done..
Thank you all guys for your replies, i really appreciate it..

Transferring file over network? what can I use besides ssh?

What can I use to transfer file over network besides using ssh?
This is only for experimental purposes. I have used ssh before, by using command like this:
(time cat /run/shm/test/input/totalInput.tar | ssh username@ip-server "cat > /dev/null") 2>>/run/shm/test/p3_UC_ctime_tar.txt
or this, if I tried to compress a file and then transfer:
(time bzip2 -kfc1 /run/shm/test/input/totalInput.tar | ssh username@ip-server "cat > /dev/null") 2>>/run/shm/test/p3_ctime_tar.txt
However, I think ssh is killing my transfer speed. I am getting only 10-20Mbps.. Router should support over 200-300Mbps.
What can I use besides ssh? I was thinking about netcat, but what I don't like is that I have to open port on the other side for each new file transfer.

Well, what I am conserned with things like scp and ssh (I tried scp too) is encryption.
I just moved one file over to a server with scp, and I got about 2.1MB/s... which is about 16.8 Mbps..
I am using Linksys E900, which is wireless-N router. Connection exist between two computers only, nothing else is using that router. However, there is another wireless point outside of our room, which is used for public University network. I don't know how much of effect it would have on our set up.
Both computers have plenty of disk space. One computer (actually development board) uses sd-card for its OS and other disk space.
About 200-300Mbps.. is just something I saw on router's specs.

Problems with open an Indesign-Document over Network

Hallo,
we have a specialized problem with opening indesign-documents over network. Our users works with windows-pc (windows7) and adobe CS5 and CS6 and they will use there documents which are on our macserver 4.0 which works on OS X 10.10.2.
Sometimes the usurers become this Message
Wouldn't work indesign proberly on windows with documents which are on a macserver?
Please help me.
best regards
chris mueller

@Naga Sai J – you cannot open an InDesign CS4 file in the previous version.
But you can export an exchange file format for InDesign CS3.
Go to File/Export and chose INX for export: "InDesign CS3 Interchange-Format (INX)"
That .inx file could be opened with InDesign CS3.
After opening the .inx file, examine it well!
Some things might have changed (things regarding to newer or changed features from InDesign CS4).

Adding artwork over network

I get a strange thing: my library (of pretty much 160 kbps AAC) is on a network drive; currently ~10mbps link. If I import to the library on that drive: all good.
However if I then add artwork, then typically the smaller songs (2 minutes or less, although this is just a guide) become unplayable and I have to burn them again. If I import them locally, add artwork and then drag them over to the network drive later, everything's fine.
Does anyone else get this? If not are you accessing your library over a 100mbps link or something similarly faster than mine?
Cheers,
Trystan

I sort of answered my own quetion - artwork for shared music that is actually playing is displayed by clicking on the triangle in the bar above artwork box, but arwork is not shown for music that is simply selected. This is likely due to increased bandwidth of need to transfer images over network; may well disappear as higher-bandwidth home networks become more common. I hope this helps someone.

Applet Security over Network

Hi, I have an Applet that requires access to the system clipboard of the client. I have never had to sign an applet before, and wanted to know if I need to have a Verisign certificate or equivalent in order to distribute this over network where I work.
The network uses NT authentication so is already secured and trusted, do I really need to go to the expense of getting a certificate just to be able to a small number of staff to use an applet at work? Or is there another way?
Many thanks in advance
AMD

Though there is already a 10 step approach for signing applets, I'll try to explain how you can sign an applet with a self signed certificate (free) and be able to manage your applet on your server so clients do not need to have a policy file on there computer. The only disadvantage of this approach is that a self signed certificate expires after one year, but since you can update your certificate on the server this should not be a big problem.
create your keystore with keypair:
keytool -genkey -keystore your_company.store -alias programmer_name
fill in the information for name company etc.
export the certificate from the store:
keytool -export -keystore your_company.store -alias programmer_name -file certificate_name.cert
Make a JAR file for your classes:
jar cvf your_applet.jar *.class
and sign your JAR file
jarsigner -keystore your_conpany.store your_applet.jar certificate_name
I always keep my certificates in another store. To this:
keytool -import -keystore all_your_certificates.store -alias programmer_name -file certificate_name.cert
Now you have got a signed applet. To post this on a server do this:
Inside the policy file you can specify the keystore location:
keystore "http://intranet.mysoft.com/admin/all_your_certificates.store", "JKS";
grant signedBy "programmer_name"
{permission java.awt.AWTPermission "accessClipboard";
permission java.awt.AWTPermission "createRobot";
permission java.awt.AWTPermission "readDisplayPixels";
Place the all_your_certificates.store and policy file on the intranet server.
The advantage of this way of working is everything can be managed remotely. As you can see, the applets that are signed by the certificate have permission for accessing the clipboard. You can specify different security settings for each certificate in the policy file.
Every visiter can now access your applet without needing the certificate installed because it can be found on the server.
