Is there any method of selecting a network speed on my set up? It is capable of running at 100mb/sec but have the feeling that it isn't. Plug in vista on a lap top and no problems at all. It's also noticeably quicker. I assume that a straight install does set up bi directional and 100mb/sec?

View 3 Replies View RelatedI'm facing an odd problem with a fresh install of OpenSuse 11.4 on a Dell PE-2950, using NIC Broadcom BCM5708C (rev 12) NetXtream II. Driver's are up to date. I'd installed vsftpd and configure it. I can connect from anywhere in the network where I setup this Server. The odd problem is that when I'm sending a big file (5.5 GiB for example), from another PE-2950 server (Windows Server 2003 64 bits R2) with another BCM5708C nic, the speed of the transfer starts at 90 MiB/s approx. but after 30 seconds , it drops to 15 MiB/s and never raise again. Driver's are up to date too.
However, from another Server in the network, a Dell R710 with SLES 10 SP3, the transfer speed is at 90-100-110 MiB/s all the time. The switch is a HP Procurve 2910al-24G, with all ports at gigabit speed. I'd tried with different FTP clients in Windows: WinSCP and the Windows's ftp client, but the result is the same: speed falls down after 30 seconds approx. using the Windows-Box.
I was a user of openSUSE 10.3. I used to get a decent speed in BitTorrent (using KTorrent 2.2.1) there, since I had earlier used Windows and the speed wasn't as good, even in Windows 7. Recently, I installed openSUSE 11.2 and found that I wasn't getting the good speeds in KTorrent. The overall performance was a fraction of what I used to get in the older Linux installation.
I decided to verify whether my suspicions were justified by again reinstalling openSUSE 10.3. When I did this, I was again able to get the great performance I used to get always with openSUSE 10.3 running KTorrent 2.2.1 I don't know what causes this, but I know that this sad thing really has happened. A newer version is actually not worth it! I hope my voice reaches the openSUSE developers and such bad incidences don't occur anymore.
Does anyone know how to revert network speeds to those attained with openSUSE11.2-64? On openSUSE11.2-64 the reported network download speed was,
max : 420 kB/s
ave : ~ 200 kB/s
After upgrade to openSUSE 11.3-64 the figures dropped to about 25% of the previous values. After upgrade to KDE 4.5 and plasmoid-networkmanagement the initial values did not change but the average value dropped after about 30 seconds to ~ 15 kB/s. Approach so far:
1. The motherboard's (A780GM-LE) build in LAN (Realtek RLT8111DL) was originally detected by openSUSE 11.3 as the Realtek RLT8169 and kernel module r8169 installed. This was replaced by the latest module r8168-8.019.00 from Realtek.
2. After kernel update to Linux 2.6.34.4-0.1-desktop x86_64 the plasmoid-networkmanagement was replace by NetworkManager-kde4. This improved flow with,
max : 140 kB/s
ave : ~ 80 kB/s
I have the problems with transfer speed between samba and Windows XP clients.
Samba server configuration:
Quad Core 6600 CPU.

Transfer speed from Samba Server to Windows 7 and XP clients:
(Windows clients copy file from Server share -> to local drive)
From Server to Windows 7 client 1:
85-90 Mb/sec
From Server to Windows 7 client 2:
90-100 Mb/sec
From Server to XP1 client 3
75-100 Mb/sec
Transfer speed from Windows 7 and XP clients TO Samba Server:
(client copy file from local drive -> to server Share)
From Server to Windows 7 client 1:
12-20 Mb/sec
From Server to Windows 7 client 2:
30-35 Mb/sec
From Server to Windows XP client 1
20-27 Mb/sec
(Copying file from Windows local drive to Windows remote share)
From Window 7 client 1 TO Windows XP client 1
40-50 Mb/sec
From Window 7 client 2 TO Windows XP client 1
50-60 Mb/sec
Copying file from Windows 7 client 2 share -> TO Windows XP client 1 show me 100-120 Mb/sec speed permanent.
Copying file from Linux hosts to NFS server is stable 50-90
Mb/sec bidirectional.

I have very slow write speed when copying file from Windows clients to Samba Share. Samba speed is slower than Windows native clients connections ?
On Linux Mint (Gnome) i used to go to Network drive. that is on the right hand side of Nautilus there is a short cut for Network. in there i could see my network hard drive and other laptops connected to the network, and i could access my files. but on OpenSuse, when i open the network folder, nothing comes up. may be it needs some sort of configuration.

Should I use iptables to set up nat or the route command or what? I just want to know the group of tools to use in order to set up my network. Network diagram: Internet <------> Debian Box <----> switch <----> hosts I found some guides but they are for linux 2.4 and i'm not sure if they are right.
To avoid having to input a password for the keyring each time I connect to the net via wireless, I enabled the 'Available to all users' option in Network Manager. Now, my question is this. Are the 'users' it refers to just those created on this machine? Would a drive-by be able to use my network without entering the password?

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.

ptables -A PREROUTING -s 178.33.23.44 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.45 -t mangle -j MARK --set-mark 2

ptables -A PREROUTING -s 178.33.23.47 -t mangle -j MARK --set-mark 2
and now I just need the tc command to read those marks and limit bandwidth, I have a gigabit connection and would like to limit each of these ip addresses to 10mbit in and out.
When I try to connect to a new network it keeps trying to use the name of the last network I connected to. This has just started happening in the last two months.
View 9 Replies View Relatedprobably this is the most idiotic question and probably i know the answer. But I want to get confirmed. Is it anyway possible that my mobile broadband speed is slow because of my installation is wrong? actually, I formatted my machine and make it dual-boot. After that my mobile-broadband speed is horrible slow. I installed (a)kmod-wl and as dependency, broadcom-wl but my lspci only shows intel network manager.

can this be related or just coincidence?
I have a Dell inspiron 640m (1405). I am a reasonably clued in linux user, but I am getting serious networking speed problems. The networking card is an intel 3945ABG When wirelessly connecting with windows XP, everything runs fine and the network connection is fast.
When connecting with any linux distro, the networking speed is abysmally slow, and the connection drops randomly. (the network is recognised and the connection is made however)
I have just formated and did a fresh install to start all over. I installed Ubuntu 9.1 and everything went fine but the network. The computer serve as a NAS and MediaPlayer. When getting a file from the server, I get a speed of 40-60mb/sec, which are good for a Gigabit network. When I try to put a file in, the speed can't pass more than 1mb/sec and often stop.
Here's the network info:
Code:
vric@XBMC:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:24:8c:a1:eb:55
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fea1:eb55/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[code]...
Edit: Looks like it's a Gigabit Problem. I connected the Ubuntu box to my Linksys router which is 10/100 and everything is MUCH faster.
Any command line tool to measure the network speed between my two linux servers without taking disk speed into account? My network is supposed to be 100Mb, but it doesn't feel like that so I wonder where the bottleneck is. The numbers that I see doesn't correlate well to that. So I'd like to know the speed network card to network card.

View 3 Replies View RelatedI have four PCs in my house that are running opensuse 11.2 and I want to create a home network to share files, scanner and printer.
View 4 Replies View RelatedI'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.
Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.
What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication
Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").
So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.
I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.
I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.
