Is it possible to diagnose the cable between the PC and switch using F14 tools? I am suspecting that something is wrong due to <100Mbit xfer rates on a gigabit connection, but can't be certain. The switch is no help as it's a cheapo one with only link/act lights.

We have a DSL , how can we calculate the available bandwidth so that we can shape the packet, We can assume the bandwidth to be 100mbps on the ethernet interface However, in DSL devices, the train rate(Bandwidth rate ) is varies according to different situation. How can i get the available bandwidth rate(from varies)?. Any method is there for getting the available bandwidth value....
View 7 Replies View RelatedI have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.
5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.

I am in the process of settign up a home server under FC14. The installation recognized both NICs, one as Intel Gigabit and the other as a Realtek Semiconductor as it should be. But when trying to start eth0 (Realtek) I get the following error message:

I am quoting form the description "Being a gully integrated card, no external plug packs are required and cabling is simplified to just an ADSL line connection. The need to purchase an extra ethernet card is also eliminated, as yjis features is build into the card. The onboard Ethernet controller (RTL8139) makes the modem appear to the OS as a standard network card. Thus the Viking can be used with almost any modern O/S without the need for special drivers. This includes Windows, Linux, Solaris, xBSD, etc.." setting ACPI=off in GRUB.conf does not fix the issue
I would like to use the collision detection routine from the OPCODE library, newest version 1.3 ... There exist documentations, e.g. Opcode.pdf and OpcodeUserManual.pdf, but they do not agree with the source code, neither the current nor the previous version 1.2.
Any working example to check if to meshes collide? I only would like to define the meshes using triangles and connectivities (no callback function). I started with a code like the following, but not successfully.

I downloaded Fedora 10 32bit and put it on a Dell Dimension 8200 to save it from the recycle bin. Everything seems to work except I cannot get an IP addr. Roadrunner is my ISP using a cable modem and a Linksys Instant Broadband Series Etherfast Cable/DSL router model BEFSR41. In system-config-network, the nic shows inactive. If I activate it a window opens saying "determining IP information for eth0". After a short time the message adds the word "failed". Using a Windows PC on the same network, I can look at the DHCP connections on the Linksys and I see the MAC addr for the PC running Fedora.
From the OS installation, /etc/sysconfig/networking/devices/ifcfg-eth0 has following:
DEVICE=eth0
HWADDR=00:80:ad:d1:88:c9
ONBOOT=yes

I'm guessing this is a r8169 problem. This worked for a while after upgrading to fc13 (from fc12)
I'm not able to get off the local network with eth0. I can though with eth1. Both interfaces are connected to the same switch and have the same network, gateway, and dns server addresses.
The odd part is I am able to ping eth0 from off the LAN and get a reply.
Wireshark capture is attached.
I can't start eth0 and have read thru many of the threads on this and can't figure it out. What does this message mean?

I just installed Fedora 10. I entered my static network info in Network Configuration. When rebooting, the eth0 says Inactive. I've read many articles about this problem on earlier versions and tried many of the suggestion, but have not found a definite way of solving this. Is there a better way or a workaround to get this machine on the network?

I use my T61 both wireless and in the dock, where I switch to the wired connection. After the latest round of updates, I seem to have lost the ability to switch to the wired network. When I turn the laptop on, I see it connect to the wireless network, but when I left click on the tray icon under Wired Network is says Device not managed.I have not made any changes to anything in the last couple weeks, besides some updates. How do I go about getting the wired network back in there?I tried to add eth0 back into System - Preferences - Network Connections, but whenever I try and add eth0, but it still says Device not managed.

Previously , I used opensuse 11.4.It has a tool in yast which allows you to choose how to configure your network adapters , traditional or knetworkmanager mode.I can't find this like tool in gnome on fedora.
how I can configure network adapters to start or not during startup?
my eth0 connection is not automatically connected when fedora starts. I checked " activate device when windows starts" in network configuration. still it is not auto connecting and after connection the network icon is not changing to connected status although it is connected.

What i am trying to do is:
1. I am trying to setup NIC via network not NetworkManager
2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1
3. #Ifconfig shows my nic and ip
4. restart the service network .
5. #ifconfig shows nothing. NO NIC card
I dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)
I tried to configure the NIC with Network Manager
When ever i restart the network service i have no out put from ifconfig
I tried to configure the NIC with #setup command as well and select the dhcp option
I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/

I've a desktop running Fedora 10 connected to the Internet via LAN. There's 3 network controllers in the desktop. One integrated to the motherboard and two additional. I would like to connect other computers (two laptops, one running fc9 and the other Window$ XP) to the Internet via the desktop. I googled the question and found out that I need to adjust thing called 'NAT'.
For that purpose I did the following:
iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -j SNAT --to-source 192.168.*.*
where 192.168.*.* - is desktop' IP address. I want to use 192.168.2.0/24 as a network for laptops. I activated one of devices (eth1), gave it IP address:
ifconfig eth1 192.168.2.0/24
and connected f9 laptop to it.
On the laptop I activated eth0 with the same IP. The problem is: it doesn't work. I can't ping anything from the laptop except its own address (192.168.2.0).
I have two network devices :
1. Intel Corporation 82574L Gigabit Network Conncection (Currently eth0, Mac=00:0e:8c:ab:c6:b1)
2. National Semiconductor Corporation DP83815 (Currently eth1, Mac=00:0e:8c:8a:70:62)
I want to change them so that the "Intel" become eth1 device and the "National" become the eth0 device.
I already tried these steps :
1. I disabled the Network Manager and enabled network
2. Edit the /etc/udev/rules.d/70-persistent-net.rules like this
Quote:
3. Change the /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth1 MAC addresses.
4. Reboot
5. After it bootup the Fedora can't recognize the devices, if I do ifconfig -a it shows "eth0_rename with FF:FF:FF:FF:FF:FF mac address".
I'm running fc10 x64 - latest updates. First I could never get wake on lan to work - spent days working on that one. Now, when I restart after a hibernate my eth0 is not re-enabled or recognized anymore. About to give up on Fedora.
I've tried service network restart.
I've tried unplugging cable and plugging back in.
I've tried init.d/networkmanager restart.
Only reboot works.
I've spent so much time trying to configure Fedore Core 10 for a Dynamips server and it's just not ready on some of the essential things like this hibernate problem and also wake on lan.
I've got a 64 bit home server system that was upgraded from FC2 to 7, 9, now 11. I've now got a weird situation where dns inquiries will not work when I reboot the machine, until i restart eth0. When I reboot, I can open firefox on the machine, put in the IP of my dsl router, and look at it's settings just fine. All other internet uses, whether it's yum,squid, or etc. comes back with the usual name server not found messages. I've got thenetwork setup to use the named on this server, ( the web's a tad bit slower when I set it up to use ISP's windows nameservers, go figure).
Anyway, a few years ago I set up the machine to use the network service to bring theseinterfaces up. (I believe this was because the early versions on Networkmanger had some issues. In an attempt to fix this issue I reset Networkmanger start at startup, and reset up eth0 and 1 to be controlled by it.I then got namserver1=XXX.XXX.XXX.XXX in resolve.conf at reboot..(yeah they were really X's, I'm not hiding an ip here) I tried going intonsswitch.conf, found the line hosts: files mdns4_minimal [NOTFOUND=return] dnsand changed it to:hosts:files dns mdns4_minimal [NOTFOUND=return]No joy, I still have to do an ifdown eth0 and an ifup eth0 to get dns to work..
When I activate eth0, the system says that the eth0 seems not exist. However, I can surf in the internet.
View 1 Replies View RelatedI am trying to get networking up on an old PII which I have successfully installed with FC4. There is a link and activity on the onboard interface because I see the indicator lights. The controller is a 3Com PCI 3c905 Boomerang 100baseTx @ 0xdc80.The only message returned by dmesg about eth0 is "Dropping NETIF_F_SG since no checksum feature."The driver module, 3c59x, is loaded as well as the mii module that depends on it.There is something about "unknown parameter`irq'" in the dmesg text regarding the driver.I noticed that eth0 is sharing an IRQ with the UHCI Host Controller.That should not be a problem, but it should not be necessary. And I could do away with USB if this is a conflict and that is the easiest way to solve it.When I drop to console at runlevel 3, and call dhclient, which is installed, I get a message telling me there is no reply to the dhcp request.I don't think the problem is on the router/switch side.
