I have installed ubuntu server 10.04 amd64. The problem is every time I login, there is no internet connection and I have to manually run "sudo ifconfig eth3 up". (eth3 has the cable). What should I do to automate that?
View 8 RepliesI'm configuring an HP Mini 110 (wireless BCM4313) to use it as a small Access Point (ad-hoc mode).
I want to make my configuration reboot friendly. With what I have right now, as soon as I reboot the laptop, the wireless interface configuration isn't correctly setup. I have to do "ifdown eth1; ifup eth1" manually.
Here is what I have in /etc/network/interfaces for the wireless interface code...
So the question is how can I avoid having to bring down and up the interface?
Every so often I need to manually IP if I'm hooking up an AP device or router and such. In windows it takes all of 10 seconds to do. In Ubuntu I know how to manually edit the /etc/networking/interfaces file but the last couple of days I figured it might be simpler to use the Networking Configuration GUI tool in System Preferences area. I edit the Auto eth0 device but it never seems to work for some reason.Can you use this tool to GUI change your IP's or do you have to stick with manual edits?

I like to disconnect the internet when I want to and connect when I want to. I've been using Etch but have now installed Lenny. This is what I've done:
Created in kwrite and saved in /home/[my username]/bin as "ifdown":
#!/bin/bash
#script to bring network interface down
ifdown eth0
Clicked "is executable" on the "permissions" tab of the properties.
Changed the ownership to root (chown root:root ifdown)
My notes tell me that this is what I did in Etch to have it working (via a shortcut on the desktop). Either my notes are incomplete/wrong, things are different in Lenny
I run an Ubuntu Server in a Virtualbox environment. Setup works fine. In virtualbox, I accidentally hit a button that generates and assigns a new mac address for the network adapter. Since then the machine does not bring eth0 up. I tried the following ifconfig eth0 down; ifconfig eth0 hw ether macaddress; ifconfig eth0 up. Then restarted networking.

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.

I have a problem with my Fedora system. Whilst I was messing around with my graphics drivers I managed to totally screw up the system, now my desktop won't start, leaving me with just the command prompt. In order to fix it I will need to get my wireless adapter connected to my home network, this is proving tricky. I understand that NetworkManager is responsible for bringing up the network but unfortunately without starting GNOME I don't have the settings available to me (through the nm-cli) or a way to configure it.
Is there a way to bring up whatever service holds the network settings without GNOME? In the meantime I am looking into alternative ways of configuring NM, perhaps through the DBUS interface? Even so, I suspect that I will still need a settings ervice at the end of it..
I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.

Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.
how graphs can be plotted on a web interface on real time ? I have a web interface coded in PHP mostly and for graphs I have jpgraphs. But the job needs the graphs to be real time not static. As of now there's a server side program that writes onto a csv file. I read data from the file and plot it using jpgraph when the page loads. Is there anyway I can code real-time dynamic graphs on a web interface ?
View 2 Replies View Relatedtoday 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?

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

I recently added a second interface to my Ubuntu 9.10 server, I now have a dsl AND Cable connection for it, Im not trying to load balance or anything sophisitcated, heres my problem.
The machines networked, I put static entries in my dhcp servers and both interfaces are up and live with dhcp, and Ive tried with dhcp and static, same problem occurs.
But my problem is that services will only respond on one interface at a time, not both.
Anyone know what the heck is going on here?

Should I make them static and remove both gateways?
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

View 5 Replies View RelatedI am using RHEL6 on a server with 3 interfaces.
eth0 is connecting via a Cisco switch to the outer world and eth1 and eth2 to internal networks.
eth1 and eth2 are working without problems all the time, however I have the following incident with eth0: although it is RUNNING, and after it works for some time (like some hours), it then becomes incapable of sending/receiving traffic. Here are more details, after the interface exits the RUNNING state:
[root@mgt ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr E4:1F:13:6C:87:74
inet addr:9.162.91.26 Bcast:9.162.91.255 Mask:255.255.255.0
inet6 addr: fe80::e61f:13ff:fe6c:8774/64 Scope:Link
UP BROADCAST MULTICAST MTU:1500 Metric:1
[Code]....
I am wondering whether there this is because there is not traffic for some time and so the interface goes to idle. Is there any parameter I can tweak in RHEL6 to force the interface to remain RUNNING even in the absence of traffic (although I would be expecting that some 802.1 packets would be periodically flowing from the switch to the interface)?

Does anyone havea good tutorial on Fedora's network scripts, how to edit them, in what order they are called, etc. What I want to do seems simple, but something in the bootup keeps changing it. Right now, I have an image of Fedora Core 7 created in a server with 2 Ethernet cards. I need to specify static IP addresses for each card. Thats simple, and I did that. Now, heres the tricky part, I need to be able to clone this image and place it onto other exact duplicates of the hardware, and have all of the settings stay the same.
What happens here, is that eth0 and eth1 are stored somewhere as devices, and upon boot on a different machine, the Fedora will mount new network cards(different MAC addresses) as eth1 and eth2. It then mvoes my ifcfg-eth0/1 to a backup, and creates two brand new network setting's files, which initialize to DHCP. This creates an issue, becuase these machines do not have monitors nor keyboards attached, nor is their a DHCP server, so its a pain when I swap the machine out, to have to go in with a keyboard/mouse/monitor and reconfigure the network settings before I can connect to it over the LAN.
So does anyone have any advice on how to do this? No matter what i tried, booting the image in a new PC caused Fedora to create two new devices and create brand new network settigns for them, both initialized to DHCP. Hell, I wouldn't care if it created brand new devices, if it would initialize them to static IP addresses that I am expecting.
My upstream DNS server is a bit slow, so I've installed the dnsmasq cacher locally. I have the service starting on runlevels 2, 3, and 5. But I can tell by Firefox's behavior that dnsmasq does not work upon boot. Firefox lets its own DNS cache expire after 60 seconds. When I do my second Google search five minutes after my first, the second DNS lookup for www.google.com is just as slow as the first.If I manually restart the dnsmasq service, I get the fast name resolutions I expect.

I'm using opensuse 11.3 32bit with LXDE. I have configured an apache tomcat server listening on port 8080. Yast was used to open udp 8080 and tcp 8080 in the firewall by manual entry under the advanced button of 'allowed services' menu.Another system was used to access the tomcat server via a firefox webbrowser. The attempt was unsuccessful. The url used was [URL]. firefox webbrowser keeps showing'connecting ...' until timeout. I'm assuming that inspite of the specified port openings in the firewall, it is somehow ignored. If I were to disable the firewall, then I can access the tomcat server with the firefox webbrowser.
