Ubuntu Servers :: Lucid Slow Throughput To Windows Machines
Jun 16, 2010
Having finally got Samba shares and printer shares working on my Lucid Lynx server, I've noticed that the throughput from/to those shares is very slow to what I was used to when I had those shares on a W2K server.Having Googled this problem, I noted that there was a known issue with this in Karmic (believe Brian Wu was looking at it). However, I don't see any results in Google as to this being a problem in Lucid.
I know ipv6 can cause a problem in this regard but having issued the command:
lsmod | grep inet6
I know that ipv6 is indeed disabled on my Lucid server. Any further information on whether the error reported in Karmic still applies in Lucid, and can this be addressed in any way?
I have a laptop and a Desktop both systems only used by myself behind a router. Ubuntu Lucid on both and 64 bit systems. I have installed NFS with the desktop as server and Laptop as client. The NFS only works with the firewalls (UFW) disabled on both machines. My current setup on the desktop ufw is
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.
I accepted the latest Natty update about which I was notified a couple of days ago (I don't remember exactly). I don't remember a new kernel being pushed out, but for the record I'm on 2.6.38-8-generic right now. I'm trying to interact with a USB compact flash reader and I'm getting ridiculously low throughput (less than 1 MB per second). Before this latest upgrade, I don't remember this being a problem.
Better yet, does anybody know what might be wrong and what I might be able to do to fix this?
At first I thought the Delay was normal. After looking around it seems that it's not true. I made a post here. The Problem seems to be related to DNS.
The Server in Question is not Online (as in on the web), all machines are on local ethernet. From What I understand DNS is to mask the IP like a named variable for each IP. I am still figuring out the ins and outs of a linux server. DNS is something I have little or no grasp over. So I need help in setting up the DNS for this scenario case. All guides I have seen seem to be for web servers which is where I stop reading and look for other guides. I have webmin and Bind9 installed on the server.
i manged to get a samba server up and running to share with my windows machines. But i still want more. My main goal is to be able to share my movies. I have a laptop hooked to my flat screen with 3TB's of external drives, thats whats acting as my server. I have ubuntu desktop installed because i use it to play movies also.
I'm looking to set up something that is a little faster than samba (yes i no trying to share through USB 2.0 external drives and a wifi connection isn't going to be real fast no matter what) but i want to be able to access my server remotely. like maybe FTP? but what i'm asking here is what protocol should i use and what programs? i was thinking gadmin-proftpd and then filezilla to access?
Im an IT manager for a small company with a small ammount of users. We already use linux for our data server and I would like to implement a domain controller. All of our user machines are WIndows XP pro.
Ive been reading up on using OpenLDAP as an alternative to active directory.
What I want is just a simple active directory like server, with a GUI if possible.
What do I need to look at and how would I go about setting this up? Im fairly proficient with Ubuntu already, I just need to be pointed in the right direction.
Is it even possible to have my windows users be able to log in to their machines using an ubuntu domain controller?
I have a Acer Revo R3610 nettop on which I installed oS11.3. It has an Atheros AR5001 wireless network adaptor.I'm getting very bad latency and throughput on with this card. In comparison my Thinkpad with Intel card achieves at least 10 times the throughput from the same location. Also when I boot my wifi will come up authenticate and then a few seconds later disconnect and reconnect. I've tried updating the kernel to 2.6.35 as one of the fixes was to improve the performance of the ath5k driver. I'm using wpa2 authentication.
I have many openvpn implementations. Every time I use windows shares over openvpn, the speed is no more than 500KB/s, in LAN environment. When I start a copy it reaches 200-300KB/s, when I start second one it reaches 500KB/s. No more is reached after more copies simultaneously. When I use linux to copy files - the first copy reaches 700KB/s, the second copy reaches 2.5MB/s (then the first grows also to 2.5MB/s), the third copy reaches also 2.5MB/s. All of these are copied simultaneously, otherwise when only one is started it sits on 700KB/s. Moreover when 2 of the 3 simultaneous copy processes end, the one left backs at 700KB/s again.
But this is linux. When I use Windows the transfer speed is no more than 400-500KB/s (LAN environment). The OpenVPN server is always ubuntu (any version - I've tried 6.06, 8.04, 10.04).
Tried the OpenVPN client in ubuntu (and the windows machine behind the ubuntu), in windows (directly installed the client on windows) and it is all the same - no more than 500KB/s.
I can not use this because it is so slooow. When only one file is copied at a time it reaches only 200KB/s!!! Searched all the google results - no one have an answer, although there are many people with the same problem.
Now, I am sure that the problem is in Windows, because when I use linux as a server and as a client, the client copies fast. But when I use windows as machine behind the client it copies slow. I don't know... something in the tcp/ip settings in windows or something...
I've got a desktop running 10.04 64bit with a broadband connection connected through usb on eth1, I also have a laptop running 10.04 32bit and I've got both connected with a cat 6 crossover cable both on eth0, connected directly without a router. I would like to share files and Internet between the two.
I have a FC12 machine installed with CUPS and a CUPS-PDF printer. Printer are shared and works fine with this URL:
I have both client machine Windows XP and Windows 7. Both has setup the above printer and print fine without any problem. I can get the PDF file from windows test print. The only problem is I face is wait for around 20 seconds for printer dialog prompt out when I press print button in Windows 7. However, my windows XP never t have this problem. The printer dialog prompt out immediately when I press print button.
I am looking for a version of vmware that manages 2 severs at the same time and that mirrors them such that if one goes down we can still work on the second and of course it also works as a backup. Also, must work on a ubuntu server I have looked but there are so many version that I don't know which one is the best.
I multiboot my Lucid with Win7 and any other Linux Distro (I frequently keep changing these, presently using or trying Fedora Lovelock).I have noticed that the time between Grub Menu display and Ubuntu Splash screen has increased by a good number of seconds. I have set my Grub to select my default OS (Lucid lynx) after 3 seconds and which it does. But after that a black screen with blinking _ is displayed for sometime before Ubuntu loads with its splash screen.
I wonder what caused this? It was not the case before when ubuntu splash appeared almost immediately after Grub menu.
I've got a few parts laying around and maybe a 100 bucks on NewEgg I can get a Windows Server going. However, I have a few questions. I already have two Ubuntu servers going. My main concern is OS updates. I have Ubuntu based distros covered via apt-cacher-ng on one of my Ubuntu servers. I also have a nice squid server going with adzapper and so on. However, I have a bunch of Windows based machines on my network, and I have very limited bandwidth. I know I can run a virtual server on my main server, but I prefer to have an actual box just for a WSUS server for personal reasons. This is only an option if there is no option for WSUS style updating through Linux on my current server.
If I have to build a low powered Windows Server box in order to just push Windows updates for XP, Vista, and 7 to save bandwidth in the long run will a copy of Windows Home Server do the trick? I read an article from MaximumPC that WHS 2.0 will have a WSUS feature, but is this feature available in WHS 1.0? This is a really crappy way of storing updates and save bandwidth, but I don't know what other options I have. I live and work in a very remote area and I've already done everything I can think of to help save bandwidth. Like having a transparent proxy server and apt-cacher-ng running. It's also helps run things a lot faster when updating Ubuntu based boxes and surfing the internet. If I could just get the Windows updates out of the way I would be golden. I'll wait for WHS 2.0 if I have to. I'm not buying a full blown copy of Windows Server just for updates, especially on a box that'll cost about 300 bucks when complete. Still better than a prebuilt WHS box advertised on NewEgg for 600 bucks.
What i want to do is ssh to another machine and have gui interface as if i was using the other machine. anywhere from a single program like just nautilus run from the server on my machine to a desktop like i was sitting at it helps. Also being able to display something on the server would be nice.
I have a WD My Book Essential Edition hard drive that has 500GBs of storage that I want to use with ubuntu and my windows machines in my house. The drives are preformatted with NTFS. Does ubuntu natively support read/write of NTFS hard drives?
We administer a small lab of Ubuntu 11.04 machines. Users authenticate via NIS to the fileserver, which then uses NFS to mount their /home directory.
From time to time, seemingly at random, the machines will lock up. After about 15 minutes, they will go back to normal.
Switching the machine to the console with/ Ctrl+Alt+F1 doesn't help either - credentials get entered, but there's still a 15 minute wait before any commands can be entered. Some error messages show up at this point about processes that were running timing out. However, the root user can log in immediately (which makes us think that this is only affecting NIS accounts).
Logging in with the root account, we can ping our NIS server, and it responds normally. We can restart the networking and NIS daemons but neither of these help.
We checked the NIS error log in /var/yp/ypserv.log and it is empty.
We used to be running a different version of Ubuntu on the client machines (10.04 LTS), but not on the server.
I may be missing something very easy here, but I have a fresh install of Ubuntu 10.04 64 bit (I have also tried 10.04 32 bit) and I cannot connect to my windows machines. I can't connect by going to the network window, or by connect to server via ip. Basically, I can see the windows machines but then I double click it, and it asks for the credentials. I'm the admin of all of the machines, and I only have one login to my windows machine, which is my name First Last. I am entering this, and my password (which I'm sure is correct) and click "Connect". It thinks for maybe a half second, then presents me a blank credentials box, wanting me to start over.
I can connect to my Macbook without any troubles.
I'm using an Acer AspireRevo 1600, wired connection.
I have Ubuntu Server 10.04 running as a samba server and a VPN server using PPTPD. I am trying to connect two users to the VPN, which I am running Windows Ultimate on one, and Windows Home Premium.
Connecting to the VPN server from any location, I get an error 619 on the windows machines, and I have googled for what feels like days about the error and can't find a working solution. I look in the /var/log/messages file and see:
Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded. pppd 2.4.5 started by root, uid 0 Using interface ppp0 Connect: ppp0 <--> /dev/pts/1 Modem hang up Connection terminated Exit.
I am running dual boot of windows professional xp and ubuntu lucid lynx.I am experiencing a slow network with ubuntu.I am connected through trend net wireless N adapter and dlink 524 wireless router.my network icon is down to 1 bar,25-30% mostly.
Upgraded from Hardy where all worked fast and the only annoying bug was a total freeze every so often. So I thought it would be good to go to the next LTS version and see if it works better. However it is very slow starting up. bootchart reports 2:44 min compared to 40 sec for Hardy and that is only the start-up. Then the real drag begins after you enter your password. It's been up to 30 min!!! before the system became responsive and did not have a solid HDD light.
So my question is where do I start troubleshooting. I'll include the bootchart and dmesg log. What else is needed to tackle this issue? I'm really in a tizzy here, since it's my wives laptop and she is not as patient as I am, to put it mildly. Do I need to downgrade back to Hardy
I just did a fresh install of Lucid on my desktop. The boot background splash screen comes up very fast, but then it is about a 1 minute wait until the login prompt appears. Then once I enter my login credentials, GNOME loads up ASAP. It wasn't this slow before I reinstalled. Anyone know why this could be? Everything works.
We got a new server with 2 network interface cards with 4 MAC addresses in total. We would like to run two virtual machines (vserver1 and vserver2); one should connect via eth1, the other via eth2, and the host (mainserver) via eth0. The content of /etc/network/interfaces is as follows:
A connection from mainserver to vserver1 or vserver2 is not possible; a ssh connection from mainserver to vserverx ends with a login to mainserver.
I'm the proud owner of a new 1U server, thought dont really know how to handle the next problem. The server runs VMWare ESXi 4.x and currently contains two virtual machines with Ubuntu server 10.04 installed on them. Both the virual machines have 50GB of Harddrive, thought one had another 1TB to use.
One of these virtual machines is going to be a fileserver (and has the 1TB for that reason) while the other machine is purely going to be used as webserver. The system uses one harddiskdrive of 1.5TB (hardware raid 1 configured)
The fileserver will contain images, which should be shown on the webserver. Therefor I need to setup a link between the images directory on the fileserver, so it can be accessed by the webserver. Now this is one and the same harddisk, but the partition is only availeble in the fileserver.
How can i configure this directory, so it can be accessed by the webserver automatically (e.g. that I dont have to remount the directory, after the fileserver has been down for whatever reason)
I am trying to build a file server with RAID 5 over a couple of 1TB HDDs, to serve about 10 client machines using Ubuntu Server. I already own a 22-port switch: HP ProCurve v1810G-24 Switch (J9450A), which I am assuming will do the job. And for the actual server I am thinking of buying: HP ProLiant DL120 1U. Will this hardware suffice, or am I missing something important to get the whole thing running?
