Ubuntu Networking :: Large File Transfers & How To Set Up A Netbook Desktop Combo

Jul 11, 2011

I tried using ssh between my netbook and desktop, but it was going to take around 30 hours to transfer 39GB over the home network. Also SSH is very sketchy and often drops connections.I've been messing with it all day and I'm quite frustrated.What I'm looking to do is use my netbook as more of a primary computer and the desktop as a storage computer. Not quite a server, because I'd like to still keep a GUI on it. I'd like to be able to keep my music and movies on the desktop and stream them to the netbook (SSH sucks for this, always drops connections). I've already set up the web client for Transmission bit torrent client so I can torrent on a machine that's almost always on and connected.

Is there a better setup for all of this? I like the netbook because of the portability; I like the desktop because it's always connected (for torrents) and it has a larger storage capacity. It would be mainly used around the house. I would like to back up a file or two while abroad, but I'm not looking to stream music while I'm across town or anything.

Networking :: Large File Transfers Start Fas Then Drop To A Crawl?

Jul 19, 2010

I need to transfer 330G of data from a hard drive in my workstation to my NAS device. The entire network is gigabit and being run with new HP procurve switches. All machines have static IP addresses. The NAS is a Buffalo Terastation PRO which has the latest firmware, is set to jumbo frames, and has just been upgraded with 4 brand new 500G drives giving us a 1.4TB raid 5 setup. My workstation is a dual Quad core xeon box running on an Intel S5000XVN board with 8G of ram. My OS is Ubuntu 10.04 x64 running on a pair of Intel X25 SSDs in a raid mirror. The data drive is a 500G SATA drive connected to my onboard controller. The file system on the SATA drive is XFS. This problem was ongoing before I got my new workstation, before we had the GB switches, and before the NAS got new drives. When I transfer a small file or folder (less than 500M) it reaches speeds of 10-11 MB/sec. When I transfer a file or folder larger than that the speed slows to a crawl (less than 2MB/sec). It has always been this way with this NAS. Changing to jumbo frames speeds up the small transfers but makes little difference in the big ones. I verified with HP that the switches are jumbo frame capable.

Ubuntu :: 10.04 Hangs During Large File Transfers?

Aug 1, 2010

I recently built a home media server and decided on Ubuntu 10.04. Everything is running well except when I try to transfer my media collection from other PCs where it's backed up to the new machine. Here's my build and various situations:

Intel D945GSEJT w/ Atom N270 CPU
2GB DDR2 SO-DIMM (this board uses laptop chipset)
External 60W AC adapter in lieu of internal PSU
133x CompactFlash -> IDE adapter for OS installation
2(x) Samsung EcoGreen 5400rpm 1.5TB HDDs formatted for Ext4

Situation 1: Transferring 200+GB of files from an old P4-based system over gigabit LAN. Files transferred at 20MBps (megabytes, so there's no confusion). Took all night but the files got there with no problem. I thought the speed was a little slow, but didn't know what to expect from this new, low-power machine.

Situation 2: Transferring ~500GB of videos from a modern gaming rig (i7, 6GB of RAM, running Windows7, etc etc). These files transfer at 70MBps. I was quite impressed with the speed, but after about 30-45 minutes I came back to find that Ubuntu had hung completely.

I try again. Same thing. Ubuntu hangs after a few minutes of transferring at this speed. It seems completely random. I've taken to transferring a few folders at a time (10GB or so) and so far it has hung once and been fine the other three times.Now, I have my network MTU set from automatic to 9000. Could this cause Ubuntu to hang like this? When I say hang I mean it freezes completely requiring a reboot. The cursor stops blinking in a text field, the mouse is no longer responsive, etc.

Server :: Large FTP Transfers Hanging CentOS?

Feb 3, 2011

I've got a server running CentOS 5.5. I used the automated iptables config tool included in the operating system to allow traffic for vsftpd, Apache and UnrealIRCd. When I send large files to FTP, even from the local network, it works fine for a while and then completely times out... on everything. IRC disconnects, FTP can't find it and when I try to ping it I get "Reply from 10.1.10.134: Destination host unreachable" where ..134 is the host address for the Win7 box I'm pinging from. This is especially frustrating as it's a headless server, and as I can't SSH into it to reboot I'm forced to resort to the reset switch on the front, which I really don't like doing.

Edit: the timeouts are global, across all machines both on the local network and users connecting in from outside.

Networking :: Slow File Transfers Using Samba?

Feb 2, 2010

I am running Samba on a debian Lenny box on a wireless home network. I find that file transfers to the samba share are very slow. It takes over a minute to copy a 40MB file to the linux box, but only 20 seconds to copy the same file to a windows XP box on the same network.

Anyways, I could use a little direction on how to proceed with this, I'm really not sure where to start,

Ubuntu Networking :: Slow File Transfers (FTP, SCP) With Intel Gigabit Or Atheros WLAN?

Nov 16, 2010

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).

Code:

skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full

[code]....

Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

Ubuntu Networking :: D-link DWA-552 Master Mode On 10.04 - File Transfers Or Bandwidth Consuming Processes

May 20, 2010

after successfully configuring the dwa-552 to work in master mode in ubuntu 10.04 (ath9k driver) I ran some file transfer tests. The download speed is very good (~50mbps) but the upload speed spikes at about 10-20mbps for the first few KB and then it's nonexistent (0-1kbps). This only affects file transfers or otherwise bandwidth consuming processes. Normal web browsing or ssh is not affected. After running a speedtest of my internet connection which is routed through the AP I could upload to the internet with 1mbps which is my inet connection maximum so apparently this is not affected. Tried the same file transfers with netcat to eliminate any other factors and had the same problem. dmesg and hostapd debug did not report anything unusual

Ubuntu Networking :: Slow Network In When Copy Large Files From Main Desktop Pc To Mediaplayer?

Dec 28, 2010

I have just rewired my LAN using Cat 6 cables. Download- and Upload speeds to my main machine are great :However, it seems my LAN speed is very slow. when I copy large files from my main desktop pc to my mediaplayer, I only reach a speed of 3,7 MB/s in Ubuntu 10.10 using SMB protocol to connect to mediaplayer. I use a Sitecom WL351 Router that works fine as far as I can see. Using my dualboot Windows 7 I can copy the same large files using same setup (same pc to same mediaplayer) I can copy with almost 10 MB/s. I appreciate a little protocol overhead in Ubuntu, but this seems to be a little too much

Ubuntu Networking :: Using Synergy Between My Desktop And My Netbook

May 23, 2011

I'm having some serious issues using Synergy between my desktop and my netbook. Both are running Ubuntu 11.04.

I installed quicksynergy from the software center and everything started ok. I wanted my desktop to be the server, I opened quick synergy and put in the IP address of my netbook, which I got from connection infromation>IP address, then hit execute and close. Next on the netbook, I opened quick synergy put in my desktop's IP address (acquired from the same location) in the "Server hostname/IP address:" box and my netbook's name in the "Screen name:" box. I hit execute and close.

Now when I move my cursor from the right side of my desktop's screen where it should move over to the netbook, the cursor jumps to the middle of the screen on the desktop and does nothing to the netbook.

Ubuntu :: Slow File Transfers On 10.10?

Oct 30, 2010

Has anyone else noticed that file transfers on Maverick are significantly slower than on Lucid? A review of Maverick on Tom's Hardware finds that it is considerably slower. My own test says: On 10.10, file copy between two NTFS drives maxes at 30 MBytes/s; on 10.04.1, the same operations clock in at 40 MBytes/s. Both drives are capable of rw speeds of 70-90 MBytes/s, which I got on WinXP, and hdparm's cached read results back that up.

why file transfers are so slow, and especially why Maverick is even slower than Lucid?

Ubuntu Networking :: Can't Do FTP Transfers

Dec 31, 2010

A little over a year ago I was using SCP to successfully transfer large files over my LAN (exact same hardware). I can't seem to do this any more, and I'm not sure why.I think it's either something with iptables, or a network card driver problem. I use the same driver for both computers (b43 wireless). I can't do FTP transfers either. They start going, but quickly stall. I've used the Firestarter (iptables gui) to allow all the correct connections.One last thing: When I tried to connect to ssh using an alfa wireless card (not sure of the drivers), I couldn't even connect to ssh period. Same settings were used.

Fedora :: File Transfers (cp, Mv And Rsync) Slow System Tremendously

Aug 24, 2011

When ever I transfer large files using cp, mv, rsync or dolphin the system will slow down to the point that it's unusable. It will sometime hang completely and not accept any input until the file is transferred. I have no clue what could be causing this problem but I know it shouldn't be happening.I am using Fedora 15 (2.6.40.3-0.fc15.x86_64) with KDE 4.6. have a Phenom II 955 processor, 6 GB of system ram and the OS and swap file is on an 80 GB SSD. Copying files in the SSD doesn't cause any problem, but moving files between my other two large HDDs causes the extreme slow down. Using htop I can see that my system load jumps to between 3 and 4, but my RAM and CPU usage stays low during the transfer. Here are two commands that take about 10 mins to run and make the system unusable while it's running. It usually transferring around 2-20GB worth of data during the transfers:

cp -a /media/data.1.5/backup/Minecraft/backups/* /media/data.0.5/backup/Minecraft/backups/
rsync -a /media/data.1.5/backup/ /media/data.0.5/backup/
/media/data.1.5/ is the mount point for a 1.5 TB internal SATA drive, and /media/data.0.5/ is the mount point for a 500 GB internal SATA drive.

Ubuntu Servers :: Samba Configuration - File Transfers Between The Machines Are Extremely Slow

Nov 1, 2010

1. When I'm not logged into the server, only the shares are visible on my Windows computer. Clicking on the share folder displays an error message. As soon as I log in at the server, the files within the shares become accessible on the Windows box.

2. File transfers between the machines are extremely slow. Watching the system monitor, there's a brief burst of network activity followed by 10-30 seconds of nothing...on a gigabit network, the effective transfer rate is ~120kbs. There's no other network activity going on that would account for this behavior.

Ubuntu Networking :: Rt2870sta Driver - Transfers Slowing And Stopping Regularly

Jul 28, 2011

I have a tenda wireless adaptor running on 11.04 natty. The USB id is: 148F 3070

Using the already installed drivers rt2800usb it can connect to all 13 channels but is very flaky, transfers slowing and stopping regularly. The rt2870sta driver is a lot more stable, but it will only connect to channels 1-11, but I need to use channel 13 due to massive wifi congestion on other channels...

I've tried iwpriv but it says there are no ioctls for the device.

Is there any way to get the installed driver rt2870sta to scan and connect to channel 13?

I've also tried to install the latest drivers from the ralink website: rt2870sta says it can see all 14 channels, but fails to scan. I also tried rt3070 driver but I cannot insmod as there are errors...

Networking :: Pure-ftpd Passive Transfers Not Working?

Jun 4, 2010

I have a dns-323 linux device that's running pure-ftpd with SSL/TLS authentication. Pure-ftpd is sitting behind a linksys router with IP 192.168.1.51. Pure-ftpd is configured for port 8021 and passive port range 55562-55663. The linksys router is configure to forward port 8021 and the passive port range to 192.168.1.51.

From outside my network I can connect to the ftp server using the WAN address of the router. I'm using filezilla 2.2.32 as my client and I choose FTP w/ explicit TLS (no other option will connect). The client will authenticate successfully with pure-ftpd but once it sets up the passive data connection and tries to do a LIST of the root directory, there's a timeout. I'm assuming this is because the passive data connection is not working. In pure-ftpd, I tried changing the passive address that it reports, to be the WAN address of the router, but it did not make a difference. I included the log from filezilla below.

Ubuntu :: Window Too Large For Desktop; Can't See Buttons (Touch Screen)?

Mar 23, 2011

I have found a few topics that touch on the problem I'm having but the solution won't work for me.

I am running a 800x480 desktop with Gnome, many windows are cut off at the bottom and I cannot click on the buttons. The standard reply to this problem seems to be hold alt and left click drag the window up.

That works just fine, the twist here is I'm accessing the desktop through a touch-screen (via vnc on an android phone) and I don't have an alt button to hold, dragging is also kind of tough.. I realize it may just be the limitations of my device, but it can't hurt to ask!

Ubuntu :: Differences Between Netbook And Desktop

Feb 13, 2010

what the actual differences are between the different versions?Is it simply in the interface or does netbook have different services running by default, different hardware detection or anything else that makes the system run any differently? I know netbook doesn't have compiz installed by default but is the rest of the package set the same? I ask because I have been having various problems with boot and audio along with a few other niggles. I was running the desktop edition through the betas and the RC with no problems at all but I installed lucid final from a netbook edition iso and have done two more fresh installs from netbook iso and seem to be having a lot more issues.
