Debian Configuration :: How To Prevent Auto Up An Interface At /etc/network/interfac
Jul 27, 2011I have a ppp0 entry with post-up options like this
mapping ppp0

map timeout: 12

If I comment those off then no such problem, hence some how ppp0 executed automatically and there is no [auto ppp0] any where. How can I stop this forcefully ?
Red Hat :: Add IPs To A Network Interface As Virtual Interface Like Eth0:0?
Apr 14, 2011I found multiple sites explaining how to add IPs to a network interface as virtual interface like eth0:0. However I can add IPs to an interface as well using the ip command: ip a a 192.168.2.2/24 dev eth0 What I want to know is how I can make this persistent on rhel/centos.

Jun 10, 2009On FC10, when system boots up, it would auto detect (from DHCP) and configure eth0.
This does not happen on FC11, but I can manually configure the interface. The entries in /etc/sysconfig/network-scripts/ifcfg-eth0 are identical on both OS releases.
Don't know if this is related, but when I run System->Administration->Bootloader, it fails system-config-boot - missing module kudzu.
Ubuntu Networking :: Auto Run Script Whenever Interface Connection State Changes?
Aug 14, 2010Upon boot of my system, I auto run a script that customizes the routing table (i.e., route -n). However, after the system is already booted up and has been running, if a network connection is dropped and re-added, like if one of the several network cables to the machine is temporarily disconnected or other, then the routing table is modified -- I assume by network manager. Presently, I need to manually re-run my script to re-customize the routing table.
I would like to have the script just run whenever there is any change to the connection state of interfaces. Anyone know how to tie in some kind of event trigger that can execute a script upon change in interfaces connection state (i.e., detect change in connection state and run the script)?
Red Hat :: Network Interface Configuration File Rewritten
Feb 20, 2011This past Friday as I was performing regular maintenance on my RHEL / CentOS servers, I ran yum upgrades on them and when they rebooted, I realized there were network issues and I could not longer access them via Ping or SSH. When I jumped on the console, I realized that it created a new 'ifcfg-eth0' file with none of my static information & the old 'ifcfg-eth0' file with all my static info had been renamed to 'ifcfg-eth0.bak'. It appears that the MAC address on the new file and the old .bak file are different and I have no idea why. I have no changed or altered anything on the server.

Oct 31, 2010For Ubuntu 10.04, I can configure the network by "Network Connections". This configuration is done by doing the following operation sequences(System->Preferences->Network Connections->wired->auto eth0). Then I can connect to and browse the internet. If I type the command "ifconfig", I can see the ip I configured for eth0. Part of the content is as blow:

I think there should be other files that keep the eth0 configuration content. What are they?

Networking :: Configure A Network Route To A Host For Testing Network Interface?
Aug 30, 2010today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15.
Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?

Networking :: Accessing Low Level Network Interface
Jul 7, 2010I would like be able to access packets coming off the network with the hopes of coding a primitive packet sniffer for learning purposes. I would also like to be able to piece together my own packets and send them out on my network. Eventually, I would also like to write a simple firewall so I want the capability to drop packets as well as let them pass. I assume I will have to access the kernel with some system calls to do this, any one have any information or resources that could help me on this project?

Networking :: Network Interface Not Coming Up Automatically At Boot?
Feb 10, 2010I installed Fedora 12 on an Eee PC 1001HA. This laptop has a Ralink RT3070 wireless chipset, for which the driver is not yet in the kernel (still in staging I believe). However I downloaded the driver, compiled it, and installed it. AFAICT, it works fine.
One small obstacle remains: I am uable to get the network interface to come up automatically; I have to run # ifconfig ra0 up. Because of this NetworkManager never sees the wireless interface, making connecting to WAPs a chore.
I created a ifconf-ra0 file in /etc/sysconfig/network-scripts, and it includes the line ONBOOT=yes, but this doesn't do the trick.

Mar 21, 2011I use chrony on my laptop thinking it would be better for it than ntp because I'm frequently connecting and disconnecting from wireless cafe access points and going in and out of suspend mode. But I've also noticed that if chrony is started before the access point is connected it never syncs to the time servers. I have to manually restart it via the service command after I connect. This doesn't seem right to me, if chrony fails to find a network at start time, doesn't it periodically try again ?
