General :: Data Transfers After The Transfer Is Completed?
Jul 30, 2010
For example I am copying data to USB-flash drive using some file manager. When the file manager shows that transfer is complete, flash drive indicator continues to light. As far as I know this is some kind of caching system...
1. Is it OK to close file manager when transfer window is closed but the flash drive indicator continues to light (data is still being copied)?
2. Is it better if I turn off this caching technology?

I am having a problem with slow data transfers with both Samba and scp. I have gigabit NIC's on both all three machines that I am transferring to and from, connected to a gigabit switch. My data transfers under both smb and scp average around 21 MBit/s, (I am using nload to monitor transfer speeds).The machines are configured as follows,1) desktop
AMD Athlon 64 X2 6000+
6 gig Corsair memory
Realtek RTL8168C(P) gigabit NIC (on board)

I would like to transfer the data from Palm desktop on my windows vista laptop to my Linux netbook. The pda has stopped working so I cannot sync directly from pda to either computers.
Is this possible and if so what software do I need for the Linux and how do I do it, I would need step by step instructions as I am new to Linux and really only use it for web-browsing and skype.

I build a new test machine where i need to bring data from live machine. the data is kind of flat files and some propreitary application axigen mail server.
now what i am suffering from, which commands to do first practise. there is remote site with 1mps speed of wireless between live and test machine. on daily basis aprox 14gb .tar.gz files it need to move it.
i found scp,rcp,rsync,sftp etc. which is fastest way to replicate or copy to remote machines.
the data is on live machine /var/opt/application and on remote same directory too /var/opt/application
i try using scp it take aprox 8-10 hours to copy single 14gb file.
if possible where to see such commands logs results, if anything get down error discontinue while copying.

anyone know why this would happen? I ran the following dd command:
Code:
dd if=/dev/sdb1 of=hard/old_dell_desk_part1.img
a USB external drive was mounted to the 'hard' directory with the standard mount command. it is a ntfs-3g filesystem. it is a mechanical drive.
same behavior with solid state memory (flash, and solid state hard drives)
3693492+0 records in
3693492+0 records out
1891067904 bytes (1.9 GB) copied, 274.562 s, 6.9 MB/s

I am using an embedded platform in which I have connected an external harddisk (/dev/sda). The SCSI driver is present and I am using the SG_IO interface for performing the SMART commands with the Hard Disk. (Unfortunately not all the HDIO ioclts are present. So I opted for the SG_IO ioctl). But the data transfer (reading/write data from/to sector) is not working with the SG_IO ioctls. So I searched for some other options. Later in one of the places, I found that we can actually mount the /dev/sda to some mount point in /mnt and then make a XFS file system (mkfs.xfs) of this.
And then we can create the directories and do file operations on this mounted directory. Here the simple read/write systems calls can be used for this. I was thinking about this implementation. But I am confused how I can map the actual LBA (Logical Block Address) to the device file offset. I mean if I want to write to the sector 5, there will be a LBA for it. So I can do lseek on my device and then write the data there. So how the mapping between LBA and device file offset can be calculated.

So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.

Recently I had a situation where I had to transfer data from a PC to a Mac. Usually we simply convert the data as necessary, ie. bookmarks, contacts, etc. move the info to a dropbox account and use Windows networking to access the dropbox from a Mac. Well, there was a network issue and it was suggested that I boot to Ubuntu and do this. We do have Ubuntu on a flash drive but I was lost from there. Can anyone point me in the direction of documentation or assist me in understanding how this would be accomplished? I have a Mac, PC and Linux box at home so hopefully I have all the necessary tools to test this out.

I am quite newbie with Linux networking and I want to know if there exist a log in Linux where errors during transfers are stored. I mean, when I'm transferring data between two hosts is there any way to log somewhere (where?) the errors or warning during the transfer? That is, connection failures, TCP or UDP errors, etc.? Is there any "log level" to select the errors to be displayed in the log not to work with a huge log file?

I'm going to be needing to copy over 2 terabytes from one drive to another in a couple of days and I need something that I can use to transfer the files with CRC checking. Something comparable to Teracopy in Windows.
Open Source is an absolute must. I'm running on Debian and getting away from Windows to get away from all of the proprietary software. If it's going to be proprietary I might aswell just boot back into Windows as far as I'm concerned.
Some of the features that would be nice but not needed
-GUI (preferably gtk)
-Pause/Resume (it's going to be a long transfer so it would be nice.)
Those would be nice but CRC checking is an absolute must have for so much data.

when I try to transfer data from my laptop to the desktop using SSH I get the following massage:
Code:
:~> ssh nobani@192.168.1.3
The authenticity of host '192.168.1.3 (192.168.1.3)' can't be established.
RSA key fingerprint is f3:94:fa:7c:f1:92:07:45:3c:5b:99:51:dc:b7:a1:ff.
Are you sure you want to continue connecting (yes/no)? I wonder is it normal massage or is there something not good?

I am running ubuntu 10.4 lts desktop and ubuntu 9.10 server with the gui active. On both of these machines the data transfer rates over usb and lan have slowed down quite considerably. Also over multiple devices, not the same hardware everytime I try to transfer something.

For the past few days, i have been trying to fix a common error related to mtp devices such as creative zen. Because of the new updated libmtp8 library, it is impossible to transfer files into any mtp devices. However there is a fix that will remove this issue.
1. Get the older karmic version of libmtp8 from here: URL...
2. Install this package from terminal using: sudo dpkg -i libmtp8*.deb
3. Lock libmtp8 from the synaptic package manager, so it doesn't get updated.
4. Uninstall and then downgrade any mtp packages (through packages.ubuntu.com) that become broken after step 2 to the karmic version.
5. Enjoy.

I have a number of queries but will start with one. I presently operate 11.04 Classic (no effects). OS is NOT set up as dual boot. As I am considering purchasing a new Desktop, I am wondering what is the best way to recover such things as folders, Firefox bookmarks etc. for four users.
I do have a external HDD which I guess could be used for a possible backup if that is the way to go! The new computer will probably have Windows 7 installed with which I assume I would probably dual boot.

I have installed Xubuntu 11.04. I want to see where when data is transfered by XUbuntu(through internet). In task manager i didn't find any such thing. In fedora there is system monitor where networking information is given to user where is such thing in XUbuntu. My main reason for asking such thing is that i have limited internet connection i don't want that Xubuntu update itself or any other such thing. you may also tell me how to stop updates of Xubuntu 11.04.

i am using NCTUns simulator and having problem while receiving message from an OBU. sending a message works properly but recving creates problem and fails. i am using exactly the same function as used by the developers in the demos but still no luck. i copy the code attch the screen shots to have a look
sendto() and recvfrom() are used for message transfer. they both return >-1 if they are executed successfully. please have a look in the screenshots. agentClientReportStatus is the built in packet format which im using here whose fields i filled manually are in the code below.
agentClientReportStatus *message,*mssg;
int remainTime,n,n2,n3,i,sendingaddress,value;
sockaddr_in cli_addr;

I am doing a project where 2 clients connect to server and communicate (chat) and transfer data one after other using sockets. I have working code for this in C language. Now our main aim is to create a communication link where two clients transfer multiple streams data parallely. To be more precise i want to transfer images files and audio files parallel at same time, so is it possible to send data parallel using one socket connection?

I am using rhel4 with kernel 2.6.9-55 ELsmp. I have recently purchased 250gb seagate portable usb HDD. I have already mounted the usb HDD by updating Kernel with mode 755 and root user. I can transfer file from usb HDD to rhel system. But I am unable to make directory or copy file from rhel4 file system to usb HDD with ntfs. It is giving error message of permission denied though the device having write permission. I have already installed ntfsprog-2.0.0 in root. But there is no improvement. Is there any thing I can do to transfer data from linux system to ntfs.

I have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.

I bought a laptop today (Compaq Presario cq62) and loaded Ubuntu 10.04 on it. Everything has been running great, but the Wifi has been acting up. It connects to my router for a few seconds to a minute, and then stops all data transfer (although it still shows that I am connected to the internet). My other computers running Mac work fine. I took my laptop to another place with wifi, and it did the same thing.
The data transfer seems to stop when there is a lot going on. Whenever I try downloading new software, it gets to exactly 5% then stops. If I disconnect the wifi, and reconnect it works again for another minute. I may need to be walked through any terminal codes.
On that note, where would be a great place to read up on using Ubuntu (online book?)
