Fedora Networking :: How To Debug A Network

Aug 27, 2009

I built my wife a new computer about a month ago, from a barebones kit. It seems to be working fine, except that it will not connect to a known-good internet connection. I can put the cable that is connected to her ethernet port on my computer (also built from a barebones kit) and my computer connects automatically. The network is a cable modem followed by a six port router. Two of the ports, plus the one my wife's computer is on, are in use, but all have been checked, and all work.I thought there might be a hardware problem with the onboard etherneet port that is part of the motherboard, but adding a separate ethernet NIC card did not help; it simply gave me another port that would not connect. I have since removed the second ethernet port.

I am using the default Fedora 10 installation from a DVD I got a few months ago with a magazine. It is exactly the same installation I put on my computer, which works fine. I also put Fedora 10, since upgraded to 11, on the machine in the basement, which also connected okay. The GUI used is Gnome.So the question is, how do I go about debugging what might be wrong? Once I find what's wrong, I will almost certainly need help fixing it, but that is for later.

Fedora Networking :: Bridged Networking And NetworkManager - No Network Connection Because Network Isn't Managed

Mar 2, 2011

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)

But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)

The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.

Is there a way to have both of these pieces of functionality?

I am using FC14

Fedora :: Random Firefox Crash - How To Debug

Feb 17, 2010

My firefox (Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.6) Gecko/20091216 Fedora/3.5.6-1.fc11 Firefox/3.5.6) on Gnome 2.26.3 will randomly crash, without any errors. /var/log/messages & /var/log/Xorg.0.log doesn't show anything that caused any errors. And it doesn't matter on which website(s) I'm busy with, it will just crash.

My PC has:

Intel Pentium(R) Dual-Core E5200 CPU
4GB DDRII Corsair RAM
3x 160GB SATAII HDD
Asus Nvidia 8800GT graphics card.

I have updated to the latest nVidia drivers

[root@Rudi-PC ~]# dmesg | grep nvidia
nvidia: module license 'NVIDIA' taints kernel.
nvidia 0000:01:00.0: setting latency timer to 64

[code]....

This is on Fedora Core 12 x86 I have disabled the only 3 Firefox plug-ins that I installed yesterday, but this problem has been looming for a long time. Something interesting that I picked up is that Thunderbird will close randomly (very seldom though) as well, so I don't know if it's Firefox specific though.

I have picked up that it happens more often when my PC's memory usage is above 2GB RAM, and memtest86+ didn't indicate any memory problems. If I have less tabs open, it happens less often, but the more tabs I have open, the more often it happens. At the same time, on the same PC, when I'm in Windows XP SP3 (dual boot), I can have many more tabs open as well as Thunderbird, Quickbooks, Photoshop CS3 and some other applications, and it doesn't cash.

Fedora :: Live / DVDinstall Hangs On Random Times - Debug It?

Jul 23, 2010

I get the newest fedora 13 dvd install & the live cd. Put on the disk and try to install. But the installer hangs on random times, so i cant install the system. Sometimes hangs on the anaconda start, others in the partition tables, others in the language section.

i try to run the live cd and install from there. Ok the first time the cd boot very nice . But when i try to install , the pc hangs again. Other times the boot from live even finish, when the last percents r coming, hangs again.

I all hangs, the dvd drive stop's and never return. So the Fan of cpu start to run very quickly and stay there forever until my patience permits.

So i use the ubuntu installer ( almost 4 years with u fedora, and need ubuntu installer!?shame on u) and search some information about the case. Yes, the last ubuntu boot,install, and run out of the box very quickly!

I see others with Dell & others brands still have problems with hangs and freezing , in boot and installs, so the first thing i search was the kernel parameters and try to use some flags.

I think the source of this kind of problem is the acpi . When i check the flag pci=noacpi or acpi=off , i have see that on the pre-anaconda start, when u choose the english language in text mode, clicking next the installer cant anymore find the media DVD, and the hard disk with the partition table. Sometimes the installer brings me the option to search in the ubuntu partitions, sometimes no.

How to debug and search the source of the problem? Any way? code...

Fedora Networking :: Connecting Home Network To Work Network

Sep 20, 2010

Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.

Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.

Fedora Networking :: Connect The Network Where The Openvpn Client Is,throught The Computer With The Client To The Other Network?

May 20, 2009

I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface

Fedora Networking :: Juniper Network Connect Didn't Work On Fedora

May 16, 2011

I just upgrade my Fedora 14 to Fedora 15 RC1.I found the critical issue for me that Juniper Network connect(SSL VPN) didn't work for me again.I wonder if the network interface name changed impact this, but I am not sure about it as I didn't see any obviously error.I can connect the VPN auth page with my username and password after I switch my Java plugin to Sun JRE( I use google Chrome).As the Java VPN applet started, it appeared for a while and shutdown again. I think the VPN auth has been passed at that time, the problem might about creating the VPN Tunnel.

Fedora Networking :: Vista / Fedora 13 - Can't See Box In Windows Network

Oct 19, 2010

I recently bought a new Netgear WNDR3300 Wireless-N router, and cannot seem to see the linux box in my windows network. (We have multiple Windows machines on my network, all in the same workgroup.) I also recently bought Avast anti-virus, and I think I have enabled the IP range of all computers to enable communication. I wonder if a media router has different needs than just the regular router I used to use. My samba file is minimal, I will post an example. I wish my Windows computer to access a drive marked /terminal on my linux box. I have a drive on my Windows marked E:Cher on my Vista box. My workgroup name is BRCR.

Fedora Networking :: Fedora 13 X64 Keeps Disconnecting From Network

Sep 29, 2010

I've seen many threads of this type, but I didn't see anyone simply say what the problem is. There's got to be something happenning to make it disconnect, and then something else makes it so it can't re-connect.What I get is that it connects for some time (maybe a short time, maybe a longer time) but eventually it just disconnects. When I try to re-connect wpa_supplicat log says simply it's trying to associate with the AP; it's associated with the AP; and then it's disconnected: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

It is a home-built with AMD64 and a D-Link DWA-160 A2 (Atheros AR9710) and Netgear extreme 300 router AP. The router log shows it is in fact connecting for a short while only to be disconnected at my computer's request.This is Fedora 13 out of the box (sort of!) except that I have the development repos and the updates repos and the RPM fusion repos installed. I have NM applet running. I use one called simply "network", and also one called "control network devices". but they all lead to the same result that it can't reconnect. If I play with it enough doing any variety of changes I can eventually get it to reconnect, but there's no telling what action was the successful one. I just think it reset whatever was bothering it. But, as I saw another thread describe, if I delete ALL network connection definitions and reboot, it will find the network and it will connect. But sooner or later I'll be back to where it disconnects.So, does anyone actually know what the major malfunction is? It should have been identified and qualified and quantified by now so that there's a simple write-up of cause and fix. But thru all my googling I can't find anything definite. If anyone has some good answer please post it so we all can benefit.

Fedora Networking :: Network Printing - 10 To XP

Mar 30, 2009

I have been trying to set up printing on my Fedora 10 machine so I can print with a remote printer on my LAN that is attached to a Windows XP machine. I went through the whole configuration process, selected a samba printer, put in the correct UNC and driver- it is an HP psc series 1210, the printer was detected when I selected browse during the configuration process so I know I've entered the right UNC. When I try to print a test page or anything for that matter the printer starts as if it is going to start printing but nothing happens. When I go into printer properties it tells me that I have a Remote Downlevel Document and that it is printing but nothing is happening. I've tried restarting the print spool service but nothing works.

Fedora Networking :: No Network / Internet With 11?

Jun 15, 2009

I've worked with Fedora 10 for quite a time, with no problems regarding network or internet.Now that I've upgraded to Fedora 11, nothing regarding networking works. I have a dual LAN nVidia controlled network card. I've tried every possible network setting (dhcp, local only, etc...) and also tried to connect 2 pc's via direct connection, all without a result.

When I activate dhcp (as I normally would do/did), fedora tries to connect (with this blue balls spinning next to the clock), but then after a while, I just says that the network doesn't connect (the little red cross over the network connection).If I try to enter the ip, gateway, etc... manually, it says that I'm connected, but I can't ping0find any other computer or router.
