I've had an issue in KDE where each time I restart my computer, I get 5-7 notifications that it wasn't able to connect to my ethernet port. (Or something close to that) I think it's trying to connect to my marvell port over and over. Has this happened with anyone else? I think I remember this happening with Ubuntu as well only it only tried to connect to that port once and then stopped trying.

I`d like to find out how to restart USB ports without restarting whole system?I googled some but solutions mentioned were refering to some modules that are not present on F14.
View 2 Replies View RelatedI am trying to setup a VPN on my FC 12 box. Looks like getting openvpn to work behind NAT is as easy as just forwarding the ports. Do I need to forward any specific protocols (GRE, etc)? Also, can I do this with one Ethernet port (IE: RJ-45 jack), or do you recommend a second ethernet port? I could add in another PCI ethernet card if it makes it easier. Anyone know if a single ethernet jack will work or do I need two?
View 2 Replies View RelatedI have a system with one (sometimes two) ethernet ports, that works happily in an old Fedora 5 build. But I can't get it to work on a new Centos 5.4 build. Original system: One dedicated ethernet port on card always connected to the systems dedicated equipment and no external access (the system is the DHCP master for that network). An optional second USB dongle that is a second ethernet port, used for debugging and development. (This is a DHCP client with full conectivity. In /etc/sysconfig/network-scripts I have ifcfg-eth0, ifcfg-eth1 and a route-eth0. Neither of the ifcfg files needs an explicit HWADDR, which means the same ones work for all boxes. And when one needs to be connected to the network all is fine.
The system is being moved to Centos 5.4, most is working with minimal change, but I am having problems with the ethernet ports. If it only has the on board ethernet connected, all is fine. If you have the USB dongle connected things go wrong: This system brings up the USB ethernet first, and tries to assign it to eth0 (which fails), and then brings up the on board ethernet as eth1 (which also fails). I have tried forcing the behaviour of the network by setting the HWADDR(s), but this does not result in the on board coming up as eth0, it comes up as __tmpxxxx as follows:
ifconfig -a
__tmp226406138 Link encap:Ethernet HWaddr 00:80:66:07:A8:63
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
[Code]...
Currently the only solution is to unplug the USB dongle through restart and plug in afterwards, and this wont work when the unit is remote and in the field.
lspci reports 07:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12) 08:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12) eth0 is picked up (light when I plug n the cable lights up). nothing for eth1.
other OSes on the same machine pick up both.
My /etc/network/interfaces file looks like
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
iface eth1 inet static
[Code]...
For those who are interested, I have an adsl modem and a router is connected to the modem. eth1 is a connection to the modem. eth0 to the router.
My first one is the network: Our routers' ethernet ports are all in use and I cant get one of them. So Im asking you what I need to buy. Our router now is a speedport w701v. The new router should have wlan and good working LAN. It shouldnt be very expensive... give me some tips what I should look for (because Im very new with router...) and maybe give me a link where they tested many routers (and where I can trust the results).
View 3 Replies View RelatedI have 2 (some future machines will have 4) ethernet ports. I want to have them configured such that if any gets unplugged, as long as at least one of them is plugged in, it can reach the network (even if via a different IP address), and it can be reached (at least when trying a working IP address). I tried this for /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static

I need to ask about Virtual Interface, as I need to use my ethernet interface to act as two ethernet ports. As I need to give eth0 an IP address and give eth0.5 another ip address, and make some natting and other issues. Can I do that with the same interface?

View 2 Replies View RelatedI had 2 Ethernet ports and neither of them were working on a fresh build a friend was struggling with. After reading the suggestions to fix the issue and thinking that there had to be an easier way I had an epiphany. I would go to my spare parts box and bring out my old Netgear GA311 and pop it into the slot. So after searching for 10 minutes I found it and installed it. Booted up the rig and it found that right away (SWEET) now that's not the fix anybody can do that, once I updated Ubuntu the on-board ports started working (that's what I'm using now). I can't explain what the update did but for a few bucks a used card in the tool box might not be a bad idea!
Mother board is a Gigabyte GAX58A-UD5 Rev.1 Personally I'm an ASUS guy.
Just recently got a new rig, and was wondering, is there a way to share internet via a switch. I understand the problems with switches is that they dont assign IPs like routers do, but if my ubuntu machine worked like a router by assigning IPs, could it work? Current setup is as such. I have one ubuntu machine with 1 ethernet port (this shall be the main preferably) 1 mac with a single ethernet port 1 modem with a single ethernet port that cannot assign more than one IP address. And a 5 port switch. Would it be possible to place the modem into the switch, get the ubuntu machine to receive the IP address, and broadcast all other address' to everyone else via the same switch and ethernet cable?
View 3 Replies View RelatedI'm currently using Ubuntu 9.1, and a motherboard which has two Ethernet ports on it.
What I would like to do is bridge these ports, so I can plug in another Ethernet cable and run it to an unmanaged switch in my room (handy for my work laptop when on-call and building other PCs, etc).
I.e. Router --> 8-Port Switch --> My PC.
Eth 0 --> 192.168.1.100 static
Eth 1 --> 5-Port Switch --> DHCP
I believe this is the config to make the ports bridged:
ifconfig Eth0 0.0.0.0
ifconfig Eth1 0.0.0.0
brctl addbr Bridge0
brctl addif Bridge0 Eth0
brctl addif Bridge0 Eth1
ifconfig Bridge0 up
- How do I save this so upon reboot it sticks?
- How do I force Eth0 to remain as a static IP of 192.168.1.100?
I have loaded Suse 10.3 on a system that has 4 Ethernet ports, all Intel chipsets. 2 ports have the 82571 chipset, 1 port has the 82573 chipset and the last one has the 82567. The 82567 chipset can use the e1000 driver and the 8257x chipsets require the e1000e driver. We are only actually using the 82571 ports.
When the system is booted, the 82567 seems to get bound to the e1000 driver and the 82573 gets bound to the e1000e driver. Doing an "lsmod" I see both drivers loaded. It appears the 82571 drivers are getting bound to the e1000 driver which is a major problem. They work for a while but eventually they lock up with enormous error counts according to "ifconfig". How I know the e1000 driver is bound to the 82571 ports is that when I remove it(modprobe -r e1000) and then try to use one of them, I get a "network unreachable". When e1000 is loaded these ports seem to work fine. I tried modding the file in /etc/sysconfig/hardware that corresponds to the PCI address of these ports(i.e., hwcfg-bus-pci-0000:08:00.0) to force the module to e1000e, but no luck there either.
How can I tell if my USB ports are 2.0 ports?
View 1 Replies View RelatedI am new using Fedora. When ever I am installing fedora 13, it is not getting ip address. Everytime manually I am opening gui mode for network as system-config-network and then checking activate when system starts option manually. After then if I restart, it is getting ip address. without doing like this, cant we do something like ifdown eth0, ifupeth0 like this so that without restart it takes ip address? Is there any command like this do get ip without restart?
View 4 Replies View RelatedI'm running F13 with KDE 4.4.4 on my desktop PC. A few months ago I had occasion to run Kalarm (invoked via "Kickoff" app launcher). Ever since that time, the Kalarm icon appears in my KDE "system tray" after I login. I power down my PC when I'm finished using it for the day.In an effort to get rid of the Kalarm icon, I changed my KDE "session manager" (System settings -> Advanced -> Session Manager) settings to: "on login: start with an empty session". But the Kalarm icon still appears in my "system tray" after the next reboot/login.I've also tried right-clicking on the Kalarm icon and selecting "quit". The icon still re-appears after the next reboot/login.Why didn't the session manager setting: "on login: start with an empty session" get rid of the Kalarm icon?
View 2 Replies View RelatedI had an aging RH 7.3 server that I decided was time to upgrade the hardware and software as well. I chose Fedora 13.This server runs an ircd with several bots connected to it. The bot in question is a perl bot based on the old dreambot script. On the RH 7.3 server, it ran forever. On the new Fedora 13 server, it does an EOF and restarts every hour, exactly one hour after it's been started.Is there something limiting the time that a perl script can execute?
View 1 Replies View RelatedThe system will also crash when booting if it is not plugged in. However, this behaviour is not consistent. The crash is not really a crash so much as a complete system freeze, where not even the numlock light on the keyboard will turn on or off. I have to do a hard reset to get it going again.The last entry before the reboot in /var/log/messeges just shows eth0 link going down.

View 1 Replies View RelatedThis individual has been within the Ohio State computer labs for sometime because educational endeavors ceased building another Linux personal computer since the last AMD Socket A smouldered within a RAM melt. (Have on idea way there was a smoulder because over clocking was not invoked!) This query is interesting because almost all of the new processors sold are sixty four bit. Flash which is still alpha or beta and a couple of Google applications have not been fully embraced upon the x84-64 architecture which is problematic!
Why? This is just a random post that might be locked or deleted but an individual has been disturbed with the lack of x86-64 application support within Linux considering Unix operating systems have been upon this architecture for an extended period compared to Microsoft operating systems. Citing that SUN or now Oracle possessed the sixty four but architecture when this individual started to dabble within the I.T. industry many years ago. There is still substantial grief that Redhat did not purchase SUN for the hardware.

I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works)
DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
My laptop was working fine on wireless till the userinterface changed and it defaulted to ethernet and now it won't let me go back on wireless How do i disable ethernet?
