Networking :: How To Log TCP And UDP Errors During Data Transfer

Aug 19, 2009

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?

Ubuntu Networking :: Transfer Of Data From PC To Mac ?

Jul 26, 2011

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.

Networking :: Data Transfer In V2V Communication (Fedora11)

Feb 27, 2010

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;
timeval now;

Fedora Networking :: Slower Data Transfer Rate In KDE V GDM?

Nov 25, 2010

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.

Ubuntu Networking :: Internet Connects But No Data Transfer?

Jul 17, 2010

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?)

Ubuntu Networking :: Transfer A Lot Of Data From Laptop To Computer?

Mar 14, 2011

I am trying to transfer a lot of data from my laptop to my computer. Both are running Ubuntu 10.04 and both have Samba installed, and folders are setup for sharing. The laptop has a 56Mbps Wireless G built in module, and the computer has a Airlink AWLL6075 Wireless N USB Adapter 300Mbps. (I got the USB adapter working with the internet, since there was an issue with it just working out the box)

I have a wireless network, since wired is out of the question. The router is a Belkin Play N600 HD if that makes any difference. When i try to transfer the files across the speed of the transfer maxes out at about 785 Kbps (My Internet speed is 7Mbps=875 KB/s). It seems that the file is being sent to the router and then the internet and back to the router and then my computer.

I figure that bottleneck is my Laptop at 56Mbps, but that still gives a theoretical max of 7MB/s even at a low connection/link counting it at 24Mbps would still be 3MB/s. I even tried making a wireless Ad-Hoc network to transfer the files but when i went to Network it wouldn't show any shares.

I'm missing something to make it go faster and i really can't figure out what it is, maybe because I am too close to it.

Ubuntu Networking :: Wireless Connecting But No Data Transfer / Solve This?

I recently did a clean install of Ubuntu 10.04 and tried using a DLink DWL-G122 dongle for a wireless connection.

It seems to connect to the wireless router, but I cannot seem to access any websites using the wireless connection. Ethernet connections to the computer work perfectly, but ethernet isn't ideal.

Networking :: Received Data - RX - Errors And Very Slow Connection

Jun 22, 2010

I have a Webserver (Co-Location) and all runs fine ... since last week. Now there are a lot of RX-ERR shown in netstat and ifconfig. And when I try to upload a external website direct on the server for example via wget, it is very very slow and hangs very often.

RX packets:2919694 errors:990386 dropped:0 overruns:0 frame:596420
TX packets:4231423 errors:0 dropped:0 overruns:0 carrier:0

I have analyse the network but I was not able to find a problem. My hoster has checked the network and all looks fine. For example my hoster has plugged-in a pc in the same switch ... and was able to do wget (load external data, like websites) in normal speed.

Since last week my websites were delivered slower as before, too. It seemed there is a network-problem ... but how can I find it?

Actually I can install moduls ... but the server needs hours. So, if you knows a good command-line tool to analyse the network.

Software :: Data Transfer With CRC Check

Jun 21, 2011

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.

OpenSUSE Network :: Transfer Data Using SSH Massage

Jun 12, 2010

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 using openSUSE11.2 with KDE on both machine

Ubuntu Multimedia :: MTP Devices Data Transfer Fix

Aug 1, 2010

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.

Ubuntu :: Way To Transfer Data To New Desktop Computer ?

May 29, 2011

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.

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?
