There is a cable plugged in to the second network card, but that interface is not configured. I'm getting a lotof "martian source" alerts because of this.If the interface eth1 isn't started because it isn't configured, why am I getting these messages?

I have an old PC running an older version of linux with two network cards serving as my firewall router. The network cards are netgear 310tx cards. Noticed traffic was not getting routed at times. Figured my switch was going bad, so I hooked up an old hub to keep keys systems communicating while I get a new switch. No problems with hub, but only has 5 ports.
Get new switch (different make/model from old one), install, a couple of my systems have connectivity problems, but others do not. Thinking it was a bad switch, returned it, got a new one just like my old one (which I thought was going bad, but worked for several years). Hook it up, paying attention to my firewall console and notice martian header messages. Network traffic not getting routed at all. The interface for connected to LAN was slow to get started (my firewall can communicate to the Internet, but LAN communication was hosed).
System would "hang" spitting out martian header messages until I disconnected LAN cable. Thinking network card may be bad, replaced it with another version of the same type. Same problems: martian header messages and traffic not getting routed.
HOWEVER, if I remove the switch and use my old hub, no problems. Networking appears to work for all systems connected to hub. Since I and my wife work from home, I'm using the hub right now (with non-essential systems not connected due to limited ports). I can only do any real experimentation at night.
I have no idea why things would work differently between using a hub vs a switch. Could something have gone awry with the linux kernel (2.4.20-46.7)?
I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.
I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

I am trying to modify the source code of a C application (quagga) in order to insert data into a mysql table. I have added 2 new source files to the source (neto_mysql, neto_trend) which in turn use mysql.h. I have also modified the Makefile.am file to include the /usr/include/mysql directory.
When trying to compile, i get the following error. What am I missing? I have minimal experience with formal C applications like this. I feel like I may also have to include the mysql.h file in the libbgp? I dont understand why it cant find the mysql functions...

I'm doing a bit of housekeeping and tidying up of programs I no longer need/use, and as some of these were installed using sbopkg I thought I would also tidy those. However when attempting to view obsolete sources via the utilities sub-menu, sbopkg seems to crash to a cli interface from the ncurses one and spews continuously the error below. This thern continues until I CTRL+C the process which of course then leaves the sbopkg pid file still showing active in /var/run. Anyone else come across this, and a possible way to prevent it.

I have attached a diagram to show the layout, but basically I have a server that has 2 nics. I use NIC1 for the server and its services. Im using VirtualBox to run VMs and want to use NIC2 for the VMs exclusively and I want the VMs on a different network completely from the host.Ive tried setting up NIC2 on the other network but I end up with networking problems on network1. Also I cant figure out how to tell VirtualBox to bind to the host NIC2.
View 2 Replies View RelatedI don't have any background in networking. Could someone tell me what are the possible options and the best solution to join two networks together?Let's say network A has the IP address of 192.168.1.0/24 and network B has the IP address of 10.0.0.0/24. Should each end of the network has a gateway server? Or should I just setup one enough? Or do we have alternate options?

View 1 Replies View RelatedUsing Fedora 15 with Gnome 3 I am unable to configure a new network connection as the configure button is greyed out.I use a network without DHCP thus auto-connect is useless and I must enter the network configuration myself. This was simple to do in Gnome 2.x but is impossible in Gnome 3 as the configure button is greyed out when your not 'connected' to the network. Also when the auto-connect fails it switches the NIC 'off'.How am I meant to connect to a network requiring manual configuration when I can only configure networks I am already connected to?FYI: I have edited the configuration of other networks which do utilise DHCP but only after the initial connection was established by DHCP.
View 4 Replies View RelatedWhat i need to do is setup a gateway with 2 red networks, reason being 1 is my internet connection and the other is my bDSL connection for our IP phone system and i need an IP range of traffic routed to the bDSL rather than internet, i can do this on individual PC's but id like to do it at the firewall level so i dont have to configure each machine on the network.
basically i want all traffic to go to internet except for say 203.x.x.x which i want routed to the bDSL router and let it handle it. Ive dome some reading and it seems ipcop and smoothwall cant do it so i was hoping with some tricky work maybe i can get ubuntu to do it for me.
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.

After I suspend (close the lid) and wake it up (open the lid) at a different location with a network connection (wired or wireless), my system always fails to connect. I need to reboot and then it sees the network and connects fine. I have tried /etc/inet.d/networking restart, but nothing changes. The only exception to this rule are two networks that have WPA security settings and are stored. I can always switch between those two. I have tried ifconfig eth0 up & down and restart networking. I have also tried to connect manually (dhclient) and no success. None of these work. I am including the output of lshw -C network.

I have an MSI Wind U100 netbook running Maverick, and it has a Realtek RTL8187SE Wireless controller according to lshw. My computer can "see" some wireless networks where they are present, meaning when I click on the little network icon at the top of my screen it shows the available networks. But when I click on them to connect, the icon does its little "connecting" motion, but I never receive any message saying "Connected" and when I open Firefox and try to browse to google.com, it says "Server not found"
View 8 Replies View RelatedI have an ethernet card connected to my LAN and a USB cell modem internet connection. I am running ubuntu 10.10. The problem is this: I can use either network, but only am connected to one of them. If I connect to both at the same time my speed drops to zero.f I disconnect one, the other starts working. I have done a lot of searching and reading, but it looks like I don't know how to find what I am looking for.My LAN was setup as 3 WinXP computers peer to peer. One of those computers was replaced by this one that I am having trouble with (computer A). Another one was replaced by one that is not yet on the network (computer C).Computer B dual boots Win XP and ubuntu 10.4.

I want to create different IP based groups so that I may assign different settings according to that group. For example
Group1
172.16.1.x For Officers
In this group I want to limit and add some restrictions along with bandwidth limitations. So that other group may not be effected with these settings
Group2
172.16.5.x For officials
Group3
172.16.8.x For Hostels
and so on. So according to this group settings I will allow the bandwidth, accessing of audio/video site. How I may configure these groups. How to create or define these IP groups and how restrictions be added in each group.
