CentOS 5 Networking :: Centos 5.2 / Hyper-V/ Bridge With Synthetic Adapters Does Not Work?

Jan 27, 2009

I have a Centos 5.2 VM running under Windows 2008 Hyper-V. If I add two "legacy Nic's" and bridge them, everything appears to work fine. However, if I remove the legacy nics and replace them with two synthetic nics (linux integration components), the nics seems to function fine UNTIL I add them to a bridge.This VM will eventually be used as a DansGuardian/Squid transparent proxy for a local library. The logical layout is represented by the attached jpg image. I have also included the ifcfg- scripts for the adapters and bridge for both scenarios.It would also be useful if someone else has Hyper-V with the integration components and dual physical nics to see if they can reproduce my symptoms on their box.Legacy Adapters:

ifcfg-br0:
DEVICE=br0
BOOTPROTO=dhcp

CentOS 5 :: Single Disk Kickstart: How To Use Upgraded Kernel

Aug 19, 2010

For portability reasons; I am building a standalone kickstart ISO; based of Cent5.2. I am to the point where I can load my ks file (linux ks=cdrom:/ks.cfg), it reads it fine; and performs the install as I want.

Where I am having a problem; is a good way to have the install use upgraded RPM's, not the base; specifically a kernel with a few needed tweaks in it; which is packaged in an rpm.

I attempted to place my kernel rpm's into the CentOS directory and rerun creatrepo; but I simply managed to corrupt the base repo on the install media.

CentOS 5 Networking :: Xen - How To Remove Virbr0 Bridge

Apr 10, 2009

I installed Xen package on a CentOS 5.3 x86_64. After a reboot I found the virbr0 bridge configured by default. I guess that "virbr0" is the name used conventionally by Red Hat to indicate the first bridge. In other Xen installations usually it would have named "xenbr0". I did not find in which configuration or script file it was created. How is it possible to remove that "virbr0" bridge?

Networking :: Vmachine On Bridge With Tap Interf: Ping Start File Transfer And Net Stops Work

Feb 21, 2011

I set up a virtual bridge for a virtual machine (qemu-kvm) using a qemutap interface:

Code:
# brctl show
bridge2 8000.0022648a3dcc no eth5
qemutap2
I can ping and ssh to the server ...
Then I try to copy (scp) a file (2.8 M) to the server and, near the end, the copy stops and the server stops responding to ping and is not able to ping nothing except itself.

"ifconfig down ; ifconfig up" and the server is on line again.

Ubuntu Networking :: Modem Upgraded - PPPoE Config Won't Work

Jun 23, 2010

I've been using an old modem from 2007, which my ISP calls Type I. It didn't have wireless connectivity and I used pppoeconf to setup my connection - username and password and set it to connect at boot time and everything was fine till today. I bought a Type II modem from my ISP and had to return the type I modem to them. Since the technician had no knowledge of Ubuntu (or Linux in general), he configured the modem in Windows 7, tested that the connection was working, tested the wireless connection in my netbook running XP and then he left.

Now I can't connect through pppoeconf in Ubuntu (running 9.10). The terminal says eth0 is listed but the 'access concentrator' or something like that isn't responding (no other process was running at that time). I feel very vulnerable while browsing in Windows so I want to get back to Ubuntu ASAP. Oh, and here's the output when I run "dhclient eth0"

Code:
Listening on LPF/eth0/00:16:76:33:d2:70
Sending on LPF/eth0/00:16:76:33:d2:70
Sending on Socket/fallback
DHCPDISCOER on eth0 to 255.255.255.255 port 67 interval 7

Debian Configuration :: Module Assistant Can't Find Kernel Headers / Work Around This?

Jul 25, 2010

I'm trying to use module-assistant to add the vboxdrv using instructions also found here in the debian forum. However, m-a can't find the linux-headers because it looks for the package linux-headers-2.6.32-5-trunk-686. I attempted to specify were the headers were by using:
m-a prepare --kernel-dir /usr/src/linux-headers-2.6.32-5-686/
but also doesn't work. Instead, I get the error:
Bad kernel version specification at /usr/bin/m-a line 566.
Anyone knows how to work around this?
By the way, the reason I am doing this is because when I installed virtualbox (following the instructions in debian wiki) there's no vboxdrv. When I try to modprobe it, I get:
FATAL: Module vboxdrv not found.

Debian Configuration :: Setting Up A Network Bridge?

Apr 9, 2011

I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?

My Win7 netbook displays this at an 'ipconfig' command:
Windows IP Configuration

Debian Configuration :: Bridge Network - Two Virtual Hosts?

Apr 1, 2011

I have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.

Something like:
- Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain)
- KVM machine with 2 NICs (192.168.1.2)
- Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic)
- Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24

I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.

General :: Compiled A Kernel With TUN/Bridge Support But Cannot Find /dev/net/tun?

Jan 20, 2011

I compiled my own kernel with tun/tap and bridge support. Both modules load fine at boot time (I could read that in the dmesg output). Now I want to use it, and the /dev/net/tun node is not there, so my application gives that error. I'm trying to bridge openvpn connections. Is it possible that udevd is not doing his work?

PS: I'm on a WD MyBook World Ed NAS device. It's ARM, so I cross compiled the kernel from my debian linux machine. I also installed debian on the NAS.)

Debian Configuration :: Creating A Network Bridge From Eth0 To Wlan0

Jan 18, 2016

I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.

Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:

(The WiFi is secured with WPA2 Enterprise)

Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

[code]....

The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?

Debian Configuration :: Use A Network Bridge To Connect Virtual Machine?

Jul 26, 2011

I'm attempting to use a network bridge to connect my virtual machine, like so:

[Code]...

The issue is that when I type the following command, I get the further following horrible error message that doesn't seem to really point me to anywhere and I can't seem to find any relevant information to my problem on the web:

root@darkstacks:~# qemu-system-i386 -hda test.img -m 128 -curses -net nic -net tap,ifname=tap0 warning: could not configure /dev/net/tun: no virtual network emulation

Does anyone have any idea what I need to do here? My processor does not have the vmx flag, as it's a 2.4GHz P4. I don't know if that might have something to do with it.

Ubuntu Installation :: Upgraded To 10.04 But Cannot Use Kernel 2.6.32-22.32+

Jun 20, 2010

I had upgraded to 10.04 but can not use kernel 2.6.32-22.32+, I had to go back to kernel 2.6.31-21. because of the default video driver had change from the one kernel to the other, and I do not know how the correct it. In 2.6.32-22 the font would change and to a smaller size and I can barely view anything because it looks like some two year old puke a box of crayons all over the screen.

Second issue is it does not matter what power-saving mode I am in, in 5 minutes time it with go into suspension. Or right after coming out of hibernate, it will go into suspension indefinitely and no coming out of it and must to a hard boot.

Ubuntu :: Upgraded Kernel - Can't Log In To XFCE

Debian :: Upgraded Kernel - Now Can't Use Certain Apps

But when I try to use certain apps, it just sits there in the taskbar trying to load for a couple minutes, then automatically closes itself. Specifically I've noticed the nvidia x-server menu and open office doing this, while they both worked fine before I upgraded the kernel. some apps will do this, while others will work fine.

Networking :: New Install Of Centos 5.5 Will Not Work On Net Work With Fixed IP Or DHCP

Jan 12, 2011

I am trying to set up an unused machine as a web server for my students.

I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.

1) The built in Realtek RTL8139 configured as eth0.

2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.

I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.

When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?

Debian Configuration :: Accidentally Upgraded Squeeze To Sid?

Jun 16, 2010

I just noticed that I had a sid line on my sources.list, at the end of all squeeze lines, and I've been updating more or less regularly. Does the ordering imply some sort of "preference", so that the first lines are preferred over the subsequent ones, or is it all about the latest version?After removing that line, and taking a look at my installed packages with synaptic, all the "latest versions" of the packages seem to be the ones that are already installed, and I click on properties, and there are no older versions available, only "##.##-### (testing)". Emphasis on "testing", rather than "sid" or "unstable". Of course I didn't check all of them, but about a dozen, and none deviated from that pattern. However, I went to double check on the web pages about the packages, and it seems that many of the squeeze's packages are at the same version of sid. I couldn't yet find one that is not.perhaps the sole fact that the sid line was on sources.list is enough to know that something happened -- as I don't recall having ever set up those configuration files about preferred sources/pins or however it's called), and suggestions on how to proceed? My hunch would be to just downgrade things gradually as they eventually fail (as I did with geeqie, which is why I suspect that there is some mess), but leave everything alone. Not try to fix what is not quite broken. And if it fails too often, go full-blown sid.

Ubuntu :: 9.10 - Kernel Upgraded - But Won't Install Headers ?

Aug 23, 2010

I'd like to upgrade a live ISO file before burning a new CD.

So, following the instructions in "How to Customise the Ubuntu Desktop CD", I chrooted to the squashfs and ran "apt-get update/upgrade/dist-upgrade", expecting apt-get to upgrade the chroot kernel... only to find out that apparently, even when being chrooted, this command upgrades the actual kernel. I guess it makes sense, but I was under the - wrong - impression that chroot would build a filesystem totally isolated from the underneath host.

So I rebooted to use this new kernel:

Next, since the Nouveau video driver requires the kernel header files, I ran the following:

Code:

I don't understand why apt-get upgrades the kernel but won't install its header files.
