I recently setup my two PC's for network file sharing using Samba. I notice the max speed I can transfer a file is 89kb/s instead of 100Mb/s. How can I increase the speed to max 100Mb/s? Both systems are running Ubuntu 9.10 w/Samba.
View 7 RepliesI believe I'm running Kubuntu 10.04, but don't quote me on that. Here's the version string from dmesg. Linux version 2.6.32-31-generic (buildd@crested) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #60-Ubuntu SMP Thu Mar 17 22:15:39 UTC 2011 (Ubuntu 2.6.32-31.60-generic 2.6.32.32+drm33.14 I have an emergent problem with my wired ethernet resetting the connection on a frequent basis. When it resets it re-negotiates the link speed and I often end up with a 10Mb/s link and on some occasions a 100Mb/s. The configured speed for the link is 1000Mb/s full duplex using a preup ethtool command. I do not use NetworkManager but have the interface configured in /etc/network/interfaces.

So what kind of speed are you getting with Samba over your local network? What speeds should I be seeing? I'm currently transferring a large amount of files from one computer to another. I'm taking everything off of a desktop drive on computer A and putting it on an IDE disk on computer B. Transfers are running at around 600-700 KB/Sec. I've seen moments, mostly when the transfer starts, where speeds were at 1000KB/Sec, but that lasts a very short while and then starts to "degrade" until it reaches 600+ KB/Sec. It then seems to level off there. Is this acceptable? Is this all I can expect to get out of a 10/100 home network? The current transfer is 2.5GB. Looks like it will take 1 hour+ to complete. Transferred 12GB last night. Was looking at 4-5 hours to complete so I left it running while I was sleeping. Personally, I think this is slow. I think it could be exponentially faster.
While I'm running these transfers I'm looking at some documentation on Samba speed tweaks. I've been adding little tidbits here and there to both smb.conf files. Some of it seems to help. Sometimes there is a noticeable difference in speed. Sometimes the changes actually cause degradation in speed. If you have a speed tweak that you would like to share the information will be gratefully accepted. Samba gurus welcome to reply. How do you set up Samba in an office environment? How do you set Samba up in an environment where performance is critical?
Maybe I should forget about Samba and try using a different transfer protocol? Am I expecting too much from Samba?I should stop before I really start to ramble. Anyhow, networking beats the heck out of the sneakernet, at any speed!As a side note, or maybe quite importantly, there is a router and a network switch (not a hub) involved here. Maybe something to consider?
I just noticed that files are transferring between my two computers at no more than 11.3Mb/s no matter what I do.
I regularly use sshfs to mount a drive on my main computer. But after noticing a dismal speed of 10Mb/s when copying a file, I thought maybe sshfs is slow. So I tried scp, and I'm getting 11.3Mb/s with scp. Using the blowfish cypher gave me no change to this, still exactly 11.3Mb/s.
I have a Gigabit network except for the cable, which is a 10meter, 100Mb/s cable.
I have a custom modified sysctl.conf file which I'll post here if needed.
Is there anything I can do about this pathetic speed ? Maybe a modification to my ssh config ? sysctl ? anything ?
We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.
I'm experiencing slow speed transfer between two wireless connected laptops running ubuntu 9.10. Using SSH to tranfer files between these two laptops, which connect to the internet via a wirelesss router, with good speed. This is why I'm surprised by this low speed : 52.3 KB/s, averaging 3 hours and 31 minutes for a 700 Mb movie. Is there any way to make this faster ?
View 3 Replies View RelatedI was wondering how to calculate some problems related to network transfer speed. If someone can show me a function to calculate network transfer speed over time, I would appreciate it.I'm in the midst of transferring 1.3TB of data to a network storage system. By looking at the stats, 4.6GB file transferred out in 6 min and 30 seconds. How long would it take to transfer 1.3TB of data?
View 3 Replies View RelatedI just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.

I have two PCs one has Windows XP the other has Ubuntu 9.10 on it, the Windows PC has no problems getting on the Internet (I'm posting this with it) and getting an IP address from the wired router. The wired router I have is ONLY wired it does not have wireless at all, it is currently setup to hand out IP addresses between 192.168.1.2 and 192.168.1.254.
The Ubunutu 9.10 PC worked great last night surfed all over the place for hours, then finally shut it down last night when I went to bed, shut down appeared to be normal like it always does when it shuts down, then this morning when I booted it up it gave error: "WIRED NETWORK - disconnected you are now offline".
I am using ubuntu in my new office, and I can't get the network working. The "official" OS installed was a Windows, and it has a special "dial-up" app for the LAN connection (not wireless). My network admin is apparently not helpful, since he actually knows nothing about the internals for the "dial-up" app (he did not even ever heard of TTLS, PEAP, MD5, etc), and claimed that no OS except for Windows can work...
Well, I have tested various configurations with my Mac laptop, and apparently the LAN connection requires 802.1X authentication, and it's using a very weird combination "TTLS+PEAP+MD5" (if I check these options in Mac OS X, the connection works). However, in NetworkManager, I can't select both TTLS and PEAP, and moreover, TTLS does not work with MD5. So, is there anything I could try?
Fresh install of UbuntuStudio 10.04. This is really bizarre.
I can't seem to connect to the wired connection mainly because there is no connections tab (pic attached).

View 9 Replies View RelatedI've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.

I have a wired problem in Ubuntu 10.10, My Ubuntu can connect with Wireless network, however it cannot connect to Wired Connection. I installed dual System, one is Ubuntu 10.10, the other one is Win7. Under Win7, I can both connect to the Internet in Wired or Wireless mode.
The more wired phenomenon is: When I plug in the cable, I can see the icon connected in my network manager. But I cannot visit any URLs. By checking the "ifconfig -a", I can see the IP addr was assigned to my eth0.
connect to wired LAN in ubuntu 10.04? I think I have specified the IP address and everything correctly. But it says no connectivity. In windows it says connected but I am unable to open any webpage.

I recently did a whole system wipe and got rid of windows all together!! Unfortunately, that means I have to start over with the whole networking thing. I know I have a bcm4311, but I have no idea what I have for a wired adapter. I know that I could search through everything to find what I need, but there is so much info for all the different versions. I have ubuntu studio. Can someone tell me the commands to type into the terminal to find out what I have for the wired network card and recommend a place to get the proper "drivers" to get my computer working again?

A while ago i attempted to use ubuntu as my default operating system and it failed, i could not get the shares to work properly and i gave up. Yes i know, may be i should have kept going.
Any way, my problem is, Im attempting to use ubuntu 11.04 now, and this time i am realy keen on going through with this, however... for some reason when i connect my wired connection cable ubuntu keeps failing to connect. this is with the auto eth0.
Can any one help me with this problem? This is one of the major things that i will need to do if i want to switch over to ubuntu.
So I had 11.04 beta and after the official release I updated,rebooted and lost all wifi and wired connectivity.

I'm running 11.04 on a Toshiba Satellite L350, and recently (well, for the past couple of weeks or so), I've been unable to connect to my network via a cable, only with wifi.
It isn't that it's unable to connect, it just doesn't show up in Network Manager.
My housemates, who run Windows, have no problems, so it's obviously something on my end...
Edit: I also tried connecting using wicd, but that doesn't detect it either.
I recently installed 11.04 on my PC (was running 9.04), and beforehand "tried it out" and networking was fine. I could access the internet no problem.I then ran the install, and fully formatted my HDD (i have 1 HDD for the OS and another for storage)It crashed halfway thorough, so no problem, i just re-formatted the hardrive and installed.However, It didnt connect to the internet, I literally tried every single forum looking for the solution, including editing the Network interface file.After a bit of diggingfound my user privileges did not allow me to connect to ethernet, and randomly use audio devices.SO, no problem I checked the boxes, but it still wont connect to the ethernet now, and it was fine before, tried re-installing twice with full format, but still doesnt work.

View 2 Replies View RelatedIt's been a while since i've been trying to deal with this problem but it was useless. I've found many related problems to this, most unsolved and those who had solution wouldn't work for me. I have few mates who have the same problem and still didn't find a solution as well. Here's the problem:
Both on my Desktop and Laptop, the network manager won't recognize that there is a cable pluged on the computer so that it would start my connection. The solution to make it work is pretty simple and its everywhere: use pppoeconf.
Altough that does the trick to make my internet work, i get another problem that i found out to be related to this one, which is: I can't use VPN. Which make me assume that one problem is related to the other, is that on my laptop, which has wireless internet, ubuntu will recognize it and then i can simple use vpn. My desktop, on the other hand, isn't that lucky and does not have wireless, so i can't just use vpn. So far, i've been using vpn on windows when needed, but switching systems is really a pain, not to say i'd rather do that on ubuntu.
Few other suggested solutions were to use 'wicd' and other network managers, altough for some people that did work accoding to what i saw on boards, that didn't really work out for me as well. Wicd coldn't recognize it either. Other suggestion was to check on some txt file on ubuntu, erase few information and let it 'fill up' automatic, it didn't work as well(sorry i don't remember all details on this one).
This problem happened on:
First, wubi for ubuntu 9.04
Ubuntu 9.04(normal install.)
Ubuntu 9.10
Happened both on my Desktop and my notebook, but the same version i installed on both of them were used on other computers and they did work on them so i strongly believe it has to do with the os itself.
I have the latest version of ubuntu on an HP dv4000 laptop fully updated. wireless worked out of the box. but the wired connection wont start. Problem is with the ubuntu install not the network. But i dont know how to configure it to work.
