This is a thread I've moved over from the install forum and is hopefully more focused. Sorry if I have violated some protocol. Problem I have a new machine build configured to dual-boot Windows 7 and OPENSUSE 11.4. Network performance in Windows is very good but network performance in OPENSUSE is very poor.

ok, we had to move one of our databases due to failing hardware. This box is newer than the old but it's just dog slow. 1st I thought it was mysql but now I am realizing it's the network. As a test, I tried copying a remote file to that box and the old server (located at the same co-lo, same provider), same switch, etc.Here are the results;
Old server:
access_log.1 100% 4192KB 1.4MB/s 00:03
New Server:
access_log.1 100% 4192KB 72.3KB/s 00:58
So now I see why people were complaining about webpage load times, etc. I can't figure out why the network latency. I looked around a bit, see below for some things, I thought mtu, nic speed, etc.
mii-tool shows;
eth0: 100 Mbit, full duplex, link ok
eth1: 100 Mbit, full duplex, link ok[code].....
Are there other things I can type to test or provide more feedback somehow to get more information.
I just installed Ubuntu 10.04 on a laptop that was given to me. It is having a lot of lag issues,especially when playing videos and visiting websites using flash. It's an Intel Pentium 4 2.4GHz machine. I think that it should perform better because I had used and AMD Sempron 2.0GHz machine with Ubuntu before and video playback was much better than this. I'm thinking that my problem is the graphics card driver. Here is the card that this machine has:
Code:
:~$ lspci | grep Radeon
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP 330M/340M/350M
The AMD machine was using a VIA graphics chipset.
I used the command "Xorg -configure" to create a xorg.conf file, hoping that might help. But it didn't. Here it is:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]...
Is there any tweaking that I can do in the xorg.conf that might help? I don't know which of those options I should set. I also tried changing the driver to "ati" but that did nothing. found some info for settings with "man radeon", I'm going to try some of those out.
I installed OpenSuSE 11.3. The only "extra" package I put in after the install was VirtualBox-ose. The firewall is disabled. I gave the machine a static IP address. I can get to the Internet from the machine. I enabled sshd to start on boot with "chkconfig sshd on" and also verified the service is running on the machine. I can ssh user@localhost from the machine as well.
When I try to connect to SSH from another machine, I get a connection refused. I verify that the firewall is down. I also try to get to VNC -- same problem: Connection refused. I ping the machine for fun. If I try to SSH again, it sometimes gives me a logon? I would check the server logs for the connection refused, but I wouldn't know where to look. I started in /var/log/messages, but nothing seemed to jump out there. I also find it strange because I can RDP to a windows guest running under VirtualBox. The Windows guest uses Bridged Network and DHCP.
I also find it interesting that I sometimes type a "ping google.com" from the 11.3 box and it will just hang - no output. Then I open firefox and get to the internet. All of a sudden, ping starts to give output. Could this be a neetwork card issue? A configuration issue? I don't know where to start.
Recently loaded 11.3 onto a virtual machine, however none of the network settings will allow me to connect to the internet. First time Ive had this happen, other distro's Ive experimented with connected with no problems. I recall seeing a similar topic some time ago (dont remember if it was here or another forum), but at the time, there had been no fix. Anyone know if this has been fixed?
View 5 Replies View RelatedI have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?
View 3 Replies View RelatedI have an OpenSuSE 11.1 in vmWare ESX and every other boot I can't access any running network services (ssh, webmin, qmail, mysql, ...) from outside. I just need to login, reboot and voila - network services are working.I gradually updated to 11.2 and 11.3 by following the wiki with success but this problem remained. So I reverted to snapshot of 11.1 and now I would like to identify and solve the problem here first.I also looked at /var/log/messages /var/log/boot.msg /var/log/lastlog but can't find anything usefull. I will now compare those files from the working and non-working boot but meanwhile someone already has an idea or experience what could be wrong?

View 3 Replies View RelatedI had an OS 11.3 machine running as an Nis server with Nfs, also providing dns, squid, samba shares and running apache
Internet connection provided by a netgear router at 192.168.0.1, server at 192.168.0.2, clients at 192.168.0.3, 192.168.0.4, etc. The clients all being configured to use the server for dns the squid running on it for their proxy, logging on with Nis using the exported server's Nfs /home share as /home on the clients
Everything was setup through Yast with some conf file editing being done later for samba and apache and all working brilliantly
Until ...
I added another network card to the server machine and set it up as a router, where they will be placed once ready the router providing the internet connection doesn't have gigabit ethernet
So I figured if I had gigabit cards in the clients and a gigabit card in the server set up for the internal zone and providing routing, then the clients using it as their router the local stuff would be more responsive, especially as they are using an nfs share for /home
I set the clients up to use the server at 192.168.1.1 for their router and changing their own local ip addresses to suit, i.e. 192.168.1.2, 192.168.1.3 etc and rebooted
Nis and nfs were no longer working, so I logged on as the local user, ecky, who's home directory isn't in the nfs share but at /ecky, the internet connection worked fine and so did everything else, dns, proxy, etc
I tried changing the nfs share and nis server to the internal card's ip, 192.168.1.1 and that didn't work either
Samba shares work at both 192.168.0.2 and 192.168.1.1, so my problem is that nis logons and nfs mounts don't work from either address
I've tried to give as much info as possible on what I've done without being too confusing ... don't know whether I succeeded
Darned annoying cos it took me a day and a half to get the gigabit card to detect properly in one of the machines...
i'm trying to run ubuntu 8.10 intrepid ibex on an old hand-me-down laptop that i got from a family member, and i've noticed that the performance is actually much worse than it was on windows xp professional (32-bit).
first of all let me give you my specs:
ibm thinkpad r32
intel mobile pentium 4-m 2.0 ghz
ati radeon mobility m6 (i think this is actually the mobility radeon 7000 igp) with 16mb ram
256 mb ram (pc-2100)
i understand that these are very low performance specs, but it feels like the computer is running very sluggishly even for those specs. the computer ran just fine in windows xp, but is extremely sluggish in ubuntu. it seems like it detected all the hardware just fine, but i feel like it may not be utilizing the cpu and/or video to the extent that it should be. a couple of places where it really seems to struggle is when first opening new programs, viewing flash intensive web 2.0 type webpages (i.e. videos), and listening to music/podcasts (with rhythmbox).
it seems like rhythmbox really kills my performance more than anything else, but the performance is poor all around compared to xp, and i feel like that shouldn't be the case. like i said, i understand that the specs are poor, but it feels like it's not even living up to those specs. i know that 8.10 is old and outdated now, but it's what i had laying around and i figured that it might perform better on this old deprecated laptop than 9.10 would anyway. am i wrong in this assumption? would 9.10 perform better for me?
I use chrony on my laptop thinking it would be better for it than ntp because I'm frequently connecting and disconnecting from wireless cafe access points and going in and out of suspend mode. But I've also noticed that if chrony is started before the access point is connected it never syncs to the time servers. I have to manually restart it via the service command after I connect. This doesn't seem right to me, if chrony fails to find a network at start time, doesn't it periodically try again ?
View 1 Replies View RelatedI know this has been covered in many threads before, but I'm stuck not finding my exact situation or an answer. I'm a newbie using a Debian Linux machine as the client and Windows XP machine as the server. I have successfully mounted the XP Network drive on the Linux machine using commands from the root terminal:
mount -t smbfs -o username="Windows Username",password=windowspassword //XPcomputername/folder /mountpoint/
However when I put the command in the ect/fstab file as suggested in several posts, I don't get any result on boot up. I.e. I can't get the network drive to mount on start up, I always have to manually mount it from the root terminal.
I have had a notebook with an ethernet plugged in cable before, sent a signal through the cable by resetting my router, and it switched my notebook on from cold. My question is, is there a way of doing this using a remote desktop client. Ideally, I would like a machine switched off at home running suse linux/windows, then have a client computer sent the remote request, this in turn activates the machine, which boots and then gives the rmote client control.
View 4 Replies View RelatedSo here is what I am trying to do. I want to connect my Open Suse 11 machine to the internet. I am almost there.
1. I configured my network card and eth0 is up.
2. I configured my DSL with user name and password and I am authenticated.
3. An IP address is assigned to me and the DNS servers are retrieved.
However I cannot ping or visit any website I use the YAST automatic configuration and kinternet to connect. Here are the gritty details
[Code]...
I do see that kinternet has trouble reading /etc/resolv.conf. It says 'permission denied' although read permissions are set on both /sbin/route and the path that it links to. This should not matter however since the existing entries are already there and valid. I also tried to turn off the firewall suspecting it could be a problem.
So I am being authenticated successfully ( verified with the logs ); assigned an IP; the route seems ok; firewall seems ok. But I cannot browse or do internet things I have been tweaking settings for 3 days now and all seems in vain. Do enlighten me on what I am doing wrong. I bet its something silly that I overlooked. I have had success configuring the same thing in red hat linux and browsing the internet without trouble. Is there something OpenSuse specific that I am missing ?
I am starting a MCSE course and part of it is to create and configure a domain etc etc I have done this and all my windows XP and 7 machines on my LAN are now functioning as part of the domain just great.
Unfortuntely, I have several Open suse machines which are currently not part of the domain yet (they are in a basic Workgroup).
get these computers onto the domain so that a user can log on using their domain credentials and I can apply security policies and what not?
regarding a remote connection from my workplace to my home system. On my home a have a connection to the ISP and the provider is allocating a dynamic IP to my router. How can I connect from my work computer to the home computer? There are other application or other stuff for making this possible?
View 5 Replies View RelatedI have been working on this for about 4 hours so I am extremely frustrated. I am trying to access windows shares from my linux box. I will worry about getting my own data shared afterwards.
I was having the authentication problem described by swerdna's sticky, and it was solved by the upgrade. However apparently that is not the main problem. samba is trying to use my ISP's DNS to resolve the internal network names. I have a vague conceptual understanding of WINS and NetBIOS - but Windows does this without any extra steps. Do I need to configure my machine to also act as a WINS? how do I do that? In my searches I found a thread about "why do windows to linux users give up?" this is why.
I'm in the situation where I'm trying to create 2 private networks using ESX server, all behind a NAT router (static ips are used). I used an openSuse11 vm as a router and was able to configure it so that a machine on one private network was able to access the public network. The problem I have now it that I need to be able to access a machine on the private network from the public network using a different set of IP's.
So if a machine in the private network has an IP of 10.1.0.222 I should be able to ping it using 10.99.0.222 or some other IP. I have never done this before and after reading up on iptables and linux routing I feel more confused than before. Is it possible to add IPs to eth0 (public) and have them mapped to machines on a private network eth1 or eth
I have created a small network using Win7 (not a home network, it's a workplace network), but cannot see the Win7 machine from my Linux box (openSUSE 11.3 32 bit). I am getting the error message "Empfangen der Speicherliste vom Server ist gescheitert" ("couldn't receive storage list from server" or so), wenn I try to connect via "Locations -> Server -> Windows Network -> 172.168.178.2 (which is the Win7 machines local IP address).
Disabling the firewall doesn't help.
My setup is a DSL router to which all my computers are connected.
Despite searching the inet for hours I couldn't find a solution.
Another problem is that from the Win7 machine I can only access the public folders on the Linux machine using the root login (not the user I used to make the folders public).
i'm a very long time opensuse user (from suse 9.0)

If i boot to fedora and boot back to windows i can no longer can access network/internet on windows! It says the network is disconnected. The cable is connected properly and this message is happening only because i booted to fedora 12 previously before booting into windows.
I did not have this problem with fedora 10, 9. recently i did an upgrade to 12 and this is one of the problems among the many other i am facing. In order to get internet back on windows i have to shutdown the pc and wait for a while and power on again to get network back on windows. the same issues exists on windowsXP64 and vista32.
I am connected to the internet like this pc->Realtek RTL8168D(P)/811D(P)->linksys router connected to pc by network cable --> DSL modem. the router connects to DSL by ppoe
My router's ip is 192.168.0.1. usually if i type this on my browser it will take me to the routers configuration. But a previous boot to fedora and i cant even access my router. its like it says "network disconnected".
why is fedora messing up my network connection? its pathetic that there is no OA in linux and it makes my life miserable.
I have a headless machine set up on my LAN which is dual boot, Ubuntu 10.04 SE and Windows. I have a printer attached to it. (HP Deskjet D1500 series) I also have a shared folder located on the machine.
Through SMB I've been able to recreate the share in Ubuntu to point to the share on Windows. When the machine is in either OS, the share can be resolved, browsed, edited, etc, from \hostsharename. Through SMB I've also been able to share a printer attached to the machine (and print to it). I have a problem though:
When the machine is in either OS, it is possible to use the same scheme to access the shared directory. This is not true with the printer. When in Windows: My Windows 7 x64 machine can connect to the printer, look for drivers, and when it doesn't find drivers in \hostprint$, it uses its own. My W7x64 machine can print a test page, and any other pages for that matter. My W7x64 machine lists the printer as "HP Deskjet D1500 series" I do not have to re-add the printer.
When in Ubuntu:I have to re-add the printer to my W7x64 machine. I have to specify the driver to use, regardless of whether I use the same print$ directory. Re-adding the printer gives me a network printer by the name of the printer, not the description (e.g. "HP Deskjet D1500 series")
My goal is to mimic the transparency of the shared directory, so whereas I've created a shared directory in Windows that persists between OSs, I want to create the network printer to persist across OSs. I can print to the printer in either OS, but the "printer" I have when the dual boot machine is in Ubuntu is NOT the "printer" I have when it's in Windows.
I need to accomplish this to avoid booting the machine into Windows for a client to print something. It seems very odd that I can make Apache, PHP, MySQL, shares, and common files persist/be identical between OSs, but not network printers. I've worked this for a few days now, exhausting what I can in information on SMB and CUPS to no avail. I am exhausted myself.
I set up a Samba server on my openSuSE 11.2 machine and I can connect to it locally with the local ip and with my actuall ip. My friend however cannot. I tried to have him ping my ip and that wouldn't even work. I'm confused and wondering why it doesn't work. We share a lot of files and this would make both of our lives much easier.
