Fedora Networking :: Bulk Abd Real Data Transfer Over Ad Hoc / WLAN Network Under Fedora 13
Aug 21, 2010
I am newbie to linux, I am dealing with Fedora core 13. I have already succeedded in building an ad hoc network and a WLAN network. My next step is to get some networking statistics such delay, throughput, etc. So, I need traffic to flow through the network for both multimedia traffic and bulk data traffic. How to send files between nodes on the network (I found commands ftp, rcp but do not know whether they are the correct choice for this). ID their any application to perform this?
Also, I want to perform some video streaming between two nodes to study the behavior of real time data transfer. Is thier any application to perform this?

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.

Recently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

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 am running Fedora-13 64 bit on my Dell Laptop, The same Laptop has Windows-7 as well (dual boot system). I have chosen ext3 filesystem while installing fedora. The file transfer speed in Fedora-13 over the network to my network drive comes out to be not more than 5MBPS.Where as in Wndows-7 I am getting the speed of around 10~12 MBPS. Also I found that copying files in USB flash drive is very slow than in Windows-7 . What could be the problem? To add it , I have another Laptop Running Ubuntu-10.04 , which also performs network transfers at 10~12 MBPS. So its just the fedora-13 who has this problem. As far as I remember this was not the case with Fedora-12

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

I installed Fedara 15 yesterday. I was running Fedora 13 before. Since I did the fresh install, my wireless network runs really really slow, i.e. a few KBs every 30 seconds whereas it ran at full speed in F13. I couldn't find the reason for it. I now tried the live-CD for Fedora 14 and it runs at full speed out of the box (whereas F15 is slow even with all updates installed).
Does somebody know a solution?
Laptop: Lenovo X201
Network Card: Ultimate-N 6300
I gathered uname, iwconfig, lspci and dmesg output for both, Fedara 15 and Fedora 14. But as the number of links is limited here in the forum they're all linked here: [URL]

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 so sorry to bother people, but I'm totally at a loss.I've searched the forum and have not found the answer.My NetworkManager icon is missing from the notification bar. Ive tried rt clicking on the top panel >add to pannel>notification area....yet it is still missing.I know that NetworkManager is installed, yet I cant even access it to connect to a wireless network. I'm able to connect to Eth0.I cant tell if my wireless card drivers are setup or not and if that makes a difference.

I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.

I recently got a laptop computer and installed 64 bit fedora 11. I can make wireless connections fine but for my ISP I require a dial in using an username and password. On my desktop this is easy I just make a DSL connection under network manager and select eth0 my wired network card as the hardware and away I go. But now I can't select the wireless card as my hardware connection so my DSL keeps on trying to connect through eth0 which is obviously not plugged in. How do I go about making this connection? I have searched google and other people have this problem but I haven't seen any replies. I have tried using pppoe-setup and manually setting the hardware as wlan0 but this doesn't seem to work as under network manager it just defaults back to eth0.

I installed Fedora 14 yesterday via the installation DVD with 3,3 GB. Everything worked fine and when I connected to my wlan and entered the WEP key I got access to the internet. But after about 5 minutes, to connection just got cut and I was again asked for the WEP passkey. But when I entered it this time, the connection failed and I was just asked again (with the same key entered, it even got it saved from last time). As you can think, this is quite annoying, since the time I have internet is not even enough to get some updates done.
Ah, and by the way: The time I have internet it just is unbelievably slow. On my Windows partation, I don't have this problem. I do have a small hint what might be the problem: When I was using Ubuntu, I always had a similar problem, but it did not even connect to my wlan once. The solution was to blacklist some driver, but since I don't know if this might be the problem on Fedora too and if the drivers are the same as on Ubuntu and since I really have no idea about the syntax of the terminal here, I was not daring to try this out.

Installed F14 on my daughters HP Pavilion a131On. I rebooted multiple times. Do I need to activate something? I'm new to all of this but read through many threads to do as much as I could myself. I used the GUI to load the rt3070 drivers rather than rpm. The GUI is easier I think and should be equivalent. Please let me know what else I need to do. Fedora has been great on my Lenovo but this usb wlan stuff has been a pain.

I'm running Fedora 15 KDE on a Sony Vaio VPCS13V9E. No problems in connecting to the wlan. Today I upgraded the system. There was an upgrade for Network Manager. After the upgrade the system is not able to connect to the modem - router (Linksys WAG320N) any more. Network manager keeps on crashing and sends messages like "network disabled" or "connection failed". Kde demon is reporting errors too. I guess the new version of Network Manager is bugged, because before the upgrade it did work well ... (unbelievable!).

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;

I installed F10 today. From live-usb wlan worked fine, but after installing it doesn't find any networks. I tried to google this problem, but everybody says wifi works out of the box. Not for me.
Solved: I disappled wireless networking and appled it again. It found all networks.

I have a Dell XPS M1330. I installed Fedora 10 on a separate partition and left Vista on the first. It was working just fine and for some reason all of the sudden it is not recognizing the Wireless controller. Vista is still working fine although I did get a couple of "WLAN controller has stopped working" errors. I suspect I may have a physical problem with the controller but I'm confused as to why Vista is still using it but Linux is not. The actual physicall "WIFI" light on the laptop does not even illuminate when I boot Linux. No wireless networks appear in the network list under Linux. Particularly since it WAS working fine for months...

Since I have installed Fedora 13 it seems that I can't connect to WLAN APs which aren't secured by WPA. I'm surprised about the inserts to the messages logfile:
[Code]...
Most surprising insert for me: Jul 5 20:43:21 nbtobiaslnx NetworkManager[1328]: <info> Config: added 'key_mgmt' value 'WPA-PSK' Is this the reason for my problem? I use KDE and Network Manager for managing my networkconnections.

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?)

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.

There is no wlan0 interface when trying to run FRITZ!WLAN USB Stick N 2.4 on OpenSuSE 11.2, though it works fine on Fedora 11 and Mandriva Spring 2009.1. All 64bit. Contrary to Fedora and Mandriva, there is no need to compile the compat-wireless module ar9170usb for OpenSuSE 11.2 because the kernel is very recent and includes this driver. Kernel: 2.6.31.5-0.1-desktop The /var/log/messages gives this after I put the stick in the PC. At first it is seen as a mass storage device:
