im compiling from source on a old rig i have, its running ubuntu 10.10 server edition and i finaly got all the dependencys installed to a point where ./configure actualy worked. but whne i try and run make this is what i get.

what rules I need to use to only allow traffic between 2 interfaces (which are part of a linux bridge) using ebtables?
So let's say I have if0, if1, if2. I want if1 to communicate with if0. I also want if2 to be able to communicate with if0. But I don't want if1 and if2 to communicate with each other.
When I use system-config-firewall, it asks what interfaces to trust. Where does it store that information for iptables (or whatever uses that info)? How iptables knows at what interfaces to use the rules?There is not that kind of information in /etc/sysconf/iptables and iptables-config.

My jaunty on DELL studio laptop seems connected to net, but I can not access any network service (ssh, firefox etc.). But when I connect a cable the cable lights blink as it should be and in wireless connection my wifi light blinks.
It was working 2 days ago without problem, and I have not done big changes recently.I removed and reinstalled network-manager and network-manager-gnome. Nothing changed. I see a message in each restart as follows (when Openafs is starting). I can reproduce it with "/etc/init.d/openafs-client restart"

I have a little problem with my Linux Suse 11.2 Server. I have unused network card with one port, and one with 4 ports and two used ports.
so->
eth1 is connected to a dsl-modem
eth2 is connected to a switch
i want my suse server to route between modem and switch.
Somehow, I can't go in the internet via eth1. I have to create a bridge br0 to go in the internet. very strange, when i delete the bridge and set eth1 as primary device, i have no internet.
How can i route from eth2 (10.x.x.x) to (eth1 or br0 (80.109.145.x) to Modem (80.109.145.1)?
I'm trying to setup the following on a red hat 5 HP DL380 server: (2 bonds mapped to 2 xen bridges on 2 different networks)
interfaces bond xen bridge network
eth0ð1 -> bond0 -> xenbr0 -> 172.16.6.0/24
eth2ð3 -> bond1 -> xenbr1 -> 172.16.5.0/24
For IP bonding I want the OS be responsible for configuring the Network Bridges(not xend). So I've commented out any line starting with '(network-script' in the /etc/xen/xend-config.sxp file.
My configuration is as follows:
1) For Bond0:
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
USERCTL=no
ONBOOT=yes
[Code].....
So the static routes that are configured, do not seem to taking effect.
Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: [URL]../Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge.
I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with.
Example of ifcfg-eth0 script:
DEVICE=eth0
HWADDR=00:16:76:D6:C9:45
ONBOOT=yes
BRIDGE=br0

I've been running 10.04 server for 3 months from a fresh install. I have been installing updates while Bind9, Apache2 and Samba worked just fine. The last time I installed updates was 3 weeks ago and it worked just fine.
Today I ran into problems where the system stopped doing its DNS stuff and wouldn't respond to pings over the network. Since I couldn't get it to respond with a keyboard and monitor attached to it I shut it down through the power switch. I then tried to restart the machine and all it would do was go through the bios and show a cursor flashing in the upper left or this odd color pattern on the screen and then reboot
I have tried pulling the HD and loaded it into my Ubuntu desktop and loaded the file system just fine. I then tried using the "rescue a broken system" option Ubuntu 10.04 32bit install disk and it seems to just sit at a flashing cursor.
I've seen some odd things pop up on the screen at times but mainly would be a flashing cursor in the upper left part of the screen.

I have very strange problem with kernels 2.6.33 and 2.6.34. I have a wireless card Linksys WMP200 using rt61pci. It connects just fine using WPA2 and works, but in less than 20 minutes I still can reach any machine on my network, but this machine cannot be reached by the others (i.e. before these 20 minutes others can ping me). With default kernel 2.6.26 (Lenny) all is OK. I do not use any firewall. When this happens logs do not change - wpa_supplicant's log is normal (associated), syslog is fine, dmesg shows no errors. Sofar I have tried this:
1. acpi=off as boot parameter
2. both new kernels 2.6.33 and 2.6.34 are compiled with CONFIG_CF80211_DEFAULT_PS disabled
3. iwconfig wlan0 power off
4. Tried ndiswrapper. The device is up and scans fine but wpa2 is not working...
5. Compiled a kernel without ACPI
This is all I did without any luck and I really need the new kernels because I have a quatech device attached to the machine...

I've been using Brasero to burn iso images on DVD-Rs, and although the burns are successful (I know by testing them), Brasero doesn't seem to perform its file/image integrity check from Tools>Check Integrity. The Brasero plugin "File checksum" or "Image checksum" is checked (can't have both checked), and when I perform a manual check with an md5 file and its burned DVD,it"always" gives me, immediately, a success message: "the file integrity was performed successfully," even when I insert a different image with the previous md5 file! So, immediate response (doesn't seem to be checking anything, I know that a 4Gb DVD md5 checking should take some time), and success whatever the DVD image used with one md5 file. Something must be wrong or the feature is broken.

I've got this really weird problem and I'm not even sure if it is a problem. I recently upgraded the RAM on my Compaq Presario Laptop from 3GB to 4GB by swapping out a 1GB DDR to a 2GB DDR so now it contains two 2GB DDRs. The BIOS shows 4096 MB of memory, Fedora shows 3955MB (Probably after the reduction for the video memory) so that's fine.
But I noticed a very quick flash during boot in between the Compaq Screen and GRUB. It only started coming after the RAM upgrade. I'm not able to make out what exactly is written. It's too fast. Will try with a proper camera at home. In any case, I could make out some large number probably in the order of gigabytes written in bytes. Again, not sure of the exact value.
So I get a little curious about this message and decide to run a memory test. It's working perfectly. Around 74%, it stops and says Memory Test Passed and moves on to check the HDD. I try the same from the BIOS. In the BIOS, it's a progress bar and no percentage value mentioned. Though the BIOS says 4096MB of memory, the progress bar also stops at roughly 75% and says passed. I'm not even sure what to search for on Google though I tried and got no similar results.
why this is happening? Since it's stopping at 75%, I have a feeling that the change in the amount of RAM hasn't been made in some place by the system.
I've got Tyan S4989 with gigabit ethernet controller Intel Corporation 82571EB. Sometimes server starts drop packets and doesn't respond to any connections and all logs doesn't contain any errors. iptables and SELinux switched off on CentOS 5.3(2.6.18-128.1.6).

View 3 Replies View RelatedI have a laptop "fura1" with two interfaces, eth0 (Ethernet) and eth1 (wifi), which I assign IPs 192.168.1.10 and 192.168.1.11 respectively. Then a desktop "fura2" with only one interface eth0 (Ethernet). Both are connected to a local network along with other appliances. My doubts arise on how to configure the /etc/hosts file of the desktop "fura2" taking in account that "fura1" has two interfaces, so two IP, but, obviously, only one hostname.
My first attempt for /etc/hosts of "fura2" was:
127.0.0.1localhost
127.0.1.1fura2
192.168.1.10 fura1 fura1.workgroup
192.168.1.11 fura1 fura1.workgroup
192.168.1.102 PDA PDA.workgroup
192.168.1.103 MT MT.workgroup
But it seems to my that assigning two different IPs to the same host is not a good solution. On the other hand, if I give different name to each interface, I will got a host with two hostname (?).
On my desktop having a NIC 3Com, connected to the company intranet and correctly working, I have added a second NIC ( Realtek RTL-8139) to connect a second small network ( three devices, instrumentation) using static addressing.The new board seems to be rekognized by Ubuntu, indicating "auto eth1" in the Network connections dialog. When I try to configure the connection, the "Apply" button is always disabled, therefore I cannot activate it. The command lspci shows that the board has been recognized but when i sent the

I am currently trying to set up two network interfaces in my laptop. The wireless connection wlan0 works fine and it's the one that I use to connect the internet. It's in the range of 192.168.0.x/24 (gateway: 192.168.0.1). The wired interface eth0 is connect to another router (gateway: 10.0.0.13 with IPs in the range of 10.0.0.x/24. The router is set up to work as an AP and the 10.0.0.x network will only be used to control a robot, so no internet access will be required in this network. The problem is that when I have both connections up, I can't access the Internet anymore. I can still ping both routers, I can enter both routers configuration pages but I can't connect to the Internet. If I unplug the network cable, Internet gets accessible again.
I'm still a novice in linux and I can't figure out how to fix this. I don't want to get into static ip for the wireless connection since I'm constantly using the laptop in different places. The objective is to use the 10.0.0.x router to have a development platform for the robot that can be used anywhere without having to reconfigure the robot for a new network, which is a real pain.
In detail, the laptop connects via wireless to the network with intenet (192.168.0.x) and also connects via cable to another wireless router(10.0.0.x). The wireless connection of the second router is used to connect to the robot. Since I can ping both routers when they're both connected, I think it may be something related to the ip routes.

For a very special project, many hardware issues, unusual limitations, etc, I'm turning my ubuntu into an access point (temporarily) by sharing the Internet from one device to another. I found out that with the devices I'm using, this can't be done with the network manager.
I need to get the internet from a device called 'tun0', to my 'wlan0', so it can broadcast it as a very special access point. I've read that there are ways to do this with the terminal.
I'm trying to configure /etc/network/interfaces to log whenever an interfaces goes up or down into a file, using this format: UP/DOWN [DD-MM-YY/HH:MM:SS]
How exactly do I use commands with the UP and DOWN directives?
So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?
