I have web application running on my server and can access this over the GUI.
This morning I can no longer access the gui interface. The activity LED flickers non stop on my nic card. I cannot ping or ssh into the server. However can access it directly from console and system is responsive when doing that. So i think this is a n/w issue... Any thoughts? How can I troubleshoot this?
2011-04-11 11:57:03 UTC I don't know what happening with my centralized log-server running octopussy. Currently it is working in a vmware setup with approx 980 Mb ram and is set in bridge mode. Currently is it set to receive logs from logs devices which are 4 in number one of which includes the core isg-1000 device. This setup is still in its test form....now what happens after some time (sometimes it taken days and sometimes just hours) when the connection (https) is suddenly lost to the apache and i can no longer access the interface. What happens more strangely my Ethernet interface gets shutdown on ubuntu. I have to restart the services by issuing /etc/init.d/networking restart.
Even at times it itself start receiving network packets on its own; without even restarting; i don't what the hell is wrong with the server. I cannot understand its erratic behavior. I need a sound and reliable Ethernet connectivity at all times because coz of loss of connectivity in my case would mean loss of logging functionality. I dnt want any time-gap in logging ...as im currently logging some highly critical devices on this server.
is it possible to access any application is not in /var/www/html/ via web interface ?

can no longer access the internet,Deleted Network Manager thinking I could reinstall it and it would be back to its default settings. Had not been able to get online for days. Offcourse now I can't get Network manager back as I have to be online for that. I think I had stuffed up the proxy settings but can't work out how to get that back to default either. What do I do now and how do I do it?
View 2 Replies View RelatedEverything was working well between my Windows 7 shares and all three of my Ubuntu machines. I just replaced my buggy belkin router with a Netgear one and now none of the Ubuntu machines can open my windows box through Nautilus. All three (one 10.04, 2 10.10) can see the Windows box but when I click on it I get the never ending password prompts. My Mac can access the Windows 7 machine fine, and all three Ubuntu boxes can access the shares with CIFS/autofs. I just can't browse the available shares using Places->Network. I'm lead to believe something on Win 7 reset when I changed the router but after two days I'm at a loss as to what it could be.

I can't access or install an operating system to my other three hard drives, C, X, and Z.I think that during the install my hard drives were changed to something other then NTFS, but Linux won't access them either.
When I use my Windows XP or Windows 7 disc, it says the drive has 0mb free, and it can't install until I delete the partition, then reformat. I don't want to do this obviously, because I don't want to format all of my data.When I go to Places > My Computer it lists my CD drive, Filesystem, and the Y drive. It doesn't show my other three hard drives.Under Palimpsest Disk Utility I can see my other three drives, but I can't access the data on them yet.
I have a Nikon Cool Pix 990 camera which I could access under Fedora 11 (and previous) using digikam and/or gphoto2. However under F12 and F13 it no longer works. When plugged in I get a Nikon Camera icon that the system thinks is a usbfs. However the camera is too old for that interface. If I unmount the device then it shows under usb-devices as having Driver=(none). How can I get it to be recognised as a non-usbfs device ?
View 2 Replies View RelatedI have a multi-user machine with several network interfaces (Ethernet, if that matters). I wish to grant selected users, or groups, full access to selected network interfaces (including ability to adjust IP address and to bind to low ports, but *only* on those interfaces). It is important to me that an user/group does not such full control over other interfaces. Granting partial, or temporary, root permissions is OK; it's a friendly environment.How do I go about it?System: Linux 2.6.recent; usual Debian setup (can be adjusted if needed).

I have been a happy Fedora user since late in the F9 release and now use F11 32 bit.Two days ago my 2wire modem/router took a dive. My ISP sent us a Motorola 3347-02 and since then my computer will not reach the internet. I have read everything I can and still haven't found the solution! Some things that I have tried: Disable network manager and do it manual, configure static IP, wipe system and reload, installed F11 on another computer.None of these have worked.Now I am booting from Ubuntu and have no issue but I can't stand Ubuntu.
View 4 Replies View RelatedI use my T61 both wireless and in the dock, where I switch to the wired connection. After the latest round of updates, I seem to have lost the ability to switch to the wired network. When I turn the laptop on, I see it connect to the wireless network, but when I left click on the tray icon under Wired Network is says Device not managed.I have not made any changes to anything in the last couple weeks, besides some updates. How do I go about getting the wired network back in there?I tried to add eth0 back into System - Preferences - Network Connections, but whenever I try and add eth0, but it still says Device not managed.
View 2 Replies View RelatedI'm running CentOS 5.4 and have problems with a USB-Ethernet network interface. It works in another, very similar environment but now I added Virtualization when installing the system. The interfaces comes up as usb0 - as usual, and I'm sending and receiving packets (PPPoE) but there seems to be a link missing so that the ppp session can be build. I wondered if this has to do with the Xen virtual environment running which installed a lot of virtual interfaces and bridges, but not for the USB interface.
The problem is that for PPPoE server, the interface must not have an IP address assigned - not an option when creating a new host interface. But even when I do so, the interface seems unlinked somehow. Funny thing, I can monitor the incoming and outgoing packets using Wireshark. I have not (yet) set up a virtual machine/guest system but the default machine is running.
We are making an embedded product based on Fedora 10 (this could change, but right now we stick to 10 because it works ok). We have an intel PC board with a build a normal ethernet adapter. Then we have a home build PCI-express card with 4 ethernet adapter build into a Xilinx FPGA (Xilinx Temac) (we got the driver from git.xilinx.com and modified it enough to make it work).
Now, by problem is: How do we control the device names of these ethernet adapters? It would be really nice to have them called eth0, eth1-eth4 in the order mentioned above, such our software always knows which to use for what.
Also: What to we do when the our adapter card is replaced because it is broken? A new card will have new MAC addresses and therefore the adapters will get new names destroying our IP configurations.
I'm just installed Fedora 14 64-bits into a server which come with Multiple network interfaces, I'm found that the naming of each network interface is not in sequences in what I'm thought (e.g: the on board network interfaces name as Eth5 and Eth6, the additional card ethernet port name from Eth0 - Eth1 and etc). How to name the interfaces as what I wish to? What should I install to allow me to rename the interfaces.
View 2 Replies View RelatedI have a ZTE HSUPA USB Modem Model:MF636 which used to work great and then is not longer detected.
I am using Fedora 12 and was having problems with the modem not been properly detected and filed a bug, which turned not to be a problem of NetworkManager, but an issue with udev.
https://bugzilla.gnome.org/show_bug.cgi?id=603433
I followed instructions to edit /lib/udev/rules.d/61-option-modem-modeswitch.rules and then it worked fine.
Now the modem is again not properly detected. Here is a copy of the results from dmesg code...
I have tried restoring the file that I edited. It was back to the stated previusly reported. I also have tried to run an older kernel. Then I updated to the latest kernel available for Fedora 12. Nothing seems to work.
running fc10 in a vmware setup Added /etc/sysconfig/network-scripts/ifcfg-eth0:0 to create another interface and all works fine (IPADDR=10.99.56.98). Would you expect this to be available after a reboot, last reboot I had to run ifup eth0:0
View 7 Replies View RelatedI am applying a virtual interface (eth0:0) which is failing after the system reboots. It actually cause the default interface (eth0) to fail as well, I must manually go in and remove the configuration for the eth:0:0 and restart the network to get it running again. How do I successfully add a Virtual interface to Fedora 11 that will stick when rebooted.

I'm a newbie on Linux and trying to find my feet so please be kind.I have installed vmware on my XP laptop and have installed fedora core 9. Network setting on the VMware is set to bridged. My interface eth0 which is using the wireless does not start on boot. I have to run ifup ifcfg-eth0.The file ifcfg-eth0 had onboot=yes and NM=no, so i changed it so that the NM=yes.However this does not resolve the problem at all. I have put the file back to its original configuration and I have disabled network manager and have had no luck
View 2 Replies View RelatedI have two network interfaces on my computer but only one of them is connected to an Ethernet cable. Until now on every Fedora release, the activated primary interface has been named as eth0 and everything has always worked well without any problem. Recently I switched to Fedora Core 12 and surprisingly I observed that for the first time, my primary interface has been considered by the system to be eth1 instead of eth0. I tried to replace the content of ifcfg-eth0 by ifcfg-eth1, yet system gave me an error that there was MAC address mismatching. I conserved their MAC addresses in their files and just replaced other connection parameters ( such as IP ADDR, NETWORK, NETMASK, etc.) but it did't work. When I do "server network restart", the command blocks.
As I try to install oracle on this system, regarding the fact that oracle requires static network configuration on the primary network interface, I don't know how to proceed in order to set eth0 as my primary interface (or rather set the current eth1 to eth0 because it is actually eth1 that refers to my activated primary network card).Just one more time, I would like to remark, that with previous versions of the Fedora Core, on the same computer (with the very same two network cards) I never had problem and I had installed oracle on the system with success, having the statically configured eth0 correctly detected by the system.
I have a set up with a computer that has two network cards and is connected to two networks. Both networks connect to the internet via separate routers that have DHCP enabled. I can set one of the routers up to do port forwarding to the computer without any complications but if I want to do the same on the other router the port forwarding from it doesn't work and I can't reach the system.
I know for a fact that the services are accessible from both networks and both routers can forward ports to other computers in their network. The networks are 10.10.0.1/24 and 172.22.0.1/24. I've tried turning off iptables but that didn't change anything.
Is there any kind of setting that could prevent the interface on the computer to reject traffic using NAT or something?
If I disable the interface on the working network (ifdown eth1) then suddenly eth0 on the other networks starts accepting requests sent to it via the router that does the port forwarding. I do however want to emphasize that services work just fine as long as the requests originate from either of the networks they are on.
I upgraded from kernel-2.6.38.6-27.fc15.x86_64 to kernel-2.6.38.7-30.fc15.x86_64. After the upgrade I no longer have a wireless interface in Network Management. I have a broadcom BCM4312, booting the previous kernel solves this problem.
View 9 Replies View RelatedI have installed Fedora 14 about 4 days ago. I have set all the networking parameters like dns path, hostname etc. I have also ensured that I select the check-box for "Enable automatically when system starts" for eth0 interface. But weirdly, whenever I boot my system(or restart), I see that the interface eth0 is disabled. I have to manually enter as root and enable it, each time I boot/reboot my system. Why is this happening? Could you please suggest a way so that I have eth0 interface enabled always when I boot up?Also, my domainname also is not boot-persistent. What steps should I take to ensure that the domainname set once persists across reboots?

View 1 Replies View RelatedOn 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.
I have a problem with my F13 and wired connections on my Acer TravelMate 2410. When I connect the inet cable it doesn't show it as connected. When I type ifconfig, it shows everything as it should.
