CentOS 5 :: Network 10Mb/s Half Duplex Only. R8168 ?

May 24, 2011

For some reason my network card started going 10Mb/s half duplex instead of 1000Mb/s full duplex. System is connected to 8x1Gb HP switch.Other devices connect fine through the switch and get full 1Gb network.I have Centos 5 with all updates. Driver comes from elrepo and as well is updated.

[root@host ~]# modinfo r8168
filename: /lib/modules/2.6.18-238.9.1.el5/weak-updates/r8168/r8168.ko

CentOS 5 Hardware :: Realtek RTL8111/8168B Operating In Half Duplex Mode?

Oct 12, 2010

I have an Asus P6T7 WS motherboard with 2 embedded NIC's.Relevant output from lspci:

0a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
0b:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
uname -a:

I am running a mail server and my POP3 clients have started complaining of slow speeds, about 10 days back. This prompted me to take remedial action on many fronts, finally I decided to look at the link itself.Attempts to force the NIC into full duplex mode using ethtool have failed. The command runs and throws me back to the prompt, but the NIC remains in half duplex mode.

Command that I have tried: ethtool -s eth1 speed 100 duplex full autoneg on modprobe -l r816*:

Fedora Networking :: VLAN Do Not Work Over Bonded Or Bridged Interfaces

Aug 20, 2011

I'm having trouble getting Fedora 15 to work with my em/bond/br configuration as it did in Fedora 14. I've got a bonding interface over em1 and em2, and then individual bond vlans (bond0.2, bond0.10, etc...), I then have a similarly named bridge interface (br0.2, br0.10, etc...) for kvm. Regardless of if I assign bond0.2 or br0.2 the IP address, I am unable to ping the gateway, but the native untagged VLAN (bond0, br0) has no issue at all.

To try to isolate this issue down to the switch or Fedora 15, I went with a plain em setup and configured em1, and em1.2 which works as expected. This issue has been plaguing me since Fedora 15 came out and I'm about to trash it and go back to Fedora 14 (Which didn't have this issue), but some of the new kvm features have kept me trying to get over this incomprehensible hump.

Networking :: Bonded Ethernet Interface Can Ping Internally But Not Externally

Oct 14, 2009

So I keep reading that bonding ethernet devices is supposed to be easy. I have followed several tutorials and tried a few things on my own, and I can't seem to get it right. I currently have a setup that allows me to ping internally on my network, but when I try to ping externally I get the error:
connect: Network is unreachable

Before I bonded the interface my connection worked fine. Here are my config files. I am running centos 5.3 on a virtual machine.

CentOS 5 Networking :: Dosen't Enslave Bonded Interfaces On Boot?

Feb 9, 2011

I have a rack of IBM x335s. They are all running 802.1Q over 802.3ad, that is VLAN trunking over two physical Ethernet bonded with LACP. Its been working fine on all of the servers for years.One server recently had its hard drives upgraded and CentOS reinstalled. It is a minimal install. The server has been reconfigured exactly as it was and has been verified and compared against the other working servers.It will not enslave the interfaces on boot. You can manually enslave and then bring up the network, so that much of the configuration is verified. It simply refuses to enslave... which fails everything that comes after thatHere is a snippet of the message log on the machine that does not enslave on boot

Networking :: LAN Speed And Duplex Setting?

Mar 22, 2010

Using ethtool I can set LAN speed and duplex setting.I have Windows PC1 configured at 100MBPS Full Duplex. I have a linux PC configured in auto-negotiation. Windows PC1 can ping linux PC2 using cross over ethernet cable but not using straight cable. Also if I set linux PC2 in 100MBPS Full Duplex mode and Windows PC1 in 100MBPS Full Duplex mode ping is not successful eiether using straight or cross over cable. Is the second PC need to be in auto negotiation mode?

Ubuntu Networking :: 10.04 Server Force Duplex Setting?

May 11, 2011

Looking to force eth0 & eth1 to 100MB Full Duplex/Auto Negotiation off but am having trouble.

When I run: "ethtool -s eth1 speed 100 duplex full autoneg off" manually, it works fine. However when I add it to the intefaces file it does not after several different configuration attempts:


# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#auto eth1
#iface eth1 inet dhcp


it seems my current configuration wont allow both eth0 and eth1 to be active at the same time. I would like them to be active-active if possible (if one goes down the other will service all traffice and vise versa).

Ubuntu Installation :: System Half Is In English And Half In Another Language After Upgrading To 10.04

May 27, 2010

I just upgraded from 9.04 to 10.04 and so far I have those problems:

1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.

2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.

4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".

5. Changing volume with keyboard shotcuts no longer works.

6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.

7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

Networking :: Bonded NICs At Host OS - Ubuntu Server - Bridged To Virtual OS - UServ - In VMware Server

Jul 19, 2009

Just something that struck me while working on our virtual servers today.

I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.

1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?

2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?

Ubuntu Networking :: D-Link N150 Dwa525 Only Half Working On 10.10

Oct 21, 2010

I've upgraded to Maverick but now I cannot get my wireless card working. In Lucid it didn't work out of the box, but worked perfectly by wrapping the Windows driver with ndiswrapper.

I noticed when I installed Maverick that wireless is enabled in Network-Manager and it gives me the option to create a wireless network or connect to a hidden network but it's not discovering/showing any of the wireless networks in range! So it seems as though the card is being recognized but the driver isn't working fully...? I tried wrapping the windows drivers, but that didn't change the situation at all.

Details of my system:

Ubuntu 10.10
2.6.35-22-generic x86_64
Desktop PC:
Intel Core i5 750

General :: Wireless Networking - Wi-Fi Connection Download Speed Is Cut In Half In Mint?

Sep 19, 2011

I have a pretty decent DSL connection that usually gave me about 105KB/second download speed over wifi. The "official" download speed was 1.5 megabits so I should have been getting a bit more, but that's not my question.

I recently switched to Mint from Ubuntu. Now my download speed is significantly slower, to the tune of 45 KB/second. Since the connection runs at normal speed when I connect via an ethernet cable, my guess is that mint doesn't give enough power to the wifi card. Is there any way I can fix that?

General :: Screen Not Showing On Laptop But Showing On Projector When Connected

Apr 18, 2011

When I try to connect a projector to my laptop (already running) and hit the fn+f7 (the designated button for switching screen), nothing happens. I see "no source found" on projector screen and my laptop screen works perfectly. Now if I restart the laptop with the projector connected, I see all the intial booting messages on the projector screen (not on my laptop), then the gnome login screen appears on both the projector screen and laptop (when the login screen appears on laptop it looks like it has lower resolution than my usual laptop resolution). But immediately after I log in, my laptop screen goes blank, and projector screen becomes the only active screen.

If I restart without the projector, again all normal operation on laptop screen is restored.

I feel like I am missing some very silly options. Any help is appreciated.

Here is the output of xrandr when the laptop is connected:

Ubuntu Networking :: Connections Not Showing Up?

Jan 12, 2010

When I click on the network manager icon next to the date in the upper right corner of my screen, my network connections do not show up. I have added two DSL connections on my laptop (username & password) but it doesn't show up. Everyday I need to use

sudo pppoeconf
if I wish to connect to the internet.

Both these connections are added in the same way on my Desktop Computer and it shows up on the network manager. One of them is even the default which connects automatically on startup.

Because it's not working I assume network manager is not compatible with my laptop. Are there patches to install or other programs that can easily manage my internet connection?

I'm using Ubuntu 9.10 on a not-so-new laptop.

Ubuntu Networking :: No Networks Showing Up ?

Aug 15, 2010

I just bought a new toshiba c655 laptop and had windows 7 on it. i made the dual boot partition on it, yada yada yada, anyway, on the windows partition i can see two networks at my house. one is mine, one is my neighbors. but when i go to the ubuntu side of things not a single wifi network shows up. i did a little combing of the forums and decided to try installing the ndisgtk package which i obviously need internet for. i thought i would plug it into an ethernet cable running straight from the modom and i could connect and download no problem. however. this has turned out to be quite a mistake. ubuntu does not even recognize the fact i have an ethernet cable plugged in. this may or may not be related, but niether my ipod or my cell phone does not show up when i plug those in and when i try to mount them i get an error message that says they could not be found. Im running 10.04.
