Fedora Networking :: Internet Not Accessible After Update / Reboot
Mar 3, 2010
After a recent update and reboot, I can no longer access the internet. Typing google.com in firefox or elinks results in firefox/links complaining about the server not found. However, I can find the server by using dig on the command line. I have checked the DNS configuration in resolve.conf and it is exactly the same as on a RHEL 5 system connects fine. The strange thing is, I can connect to other local machines in my domain just fine but can not connect to any other machine on the internet on this one Fedora 12 host even though I can on all other machines!

I've been flipping through distros a lot lately, trying to find which one best suits me. I like Ubuntu quite a bit.
I just installed Ubuntu 9.10 on a desktop pc and I'm having and issue with shared folders. I set up a test share by right clicking on Documents in my home folder, and clicking on Sharing Options. Then I checked the box to "Share this folder" and the box to "allow others to create and delete files in this folder". I click "Create Share" and in a new window, it prompts me for nautilus to add permissions automatically. So I allow it to do that.
Then, from a Virtualbox Ubuntu machine, I can access the share and do everything I want to do (view, create, modify files). However, once I reboot my Ubuntu 9.10 machine, that has the shared folder on it, it's no longer shared when I log in and check on it.
The sharing emblem has disappeared from the folder icon, but if I go into Sharing Options, the boxes are still checked. If I simply unshare and re-share the folder, it gets the sharing emblem again and the Ubuntu virtual box can access it again.

I'm a new user of Ubuntu. I requested the Ubuntu 9.10 cd online and got it in around 3 weeks. I've chosen the 'Install over windows' option for my use right now. The version of windows being 'Windows 7'. The problem is that I'm unable to connect to the internet. I'm using LAN cord to connect to my modem. The 'Network Manager' tht the user manual talks about, is not to be found yet. When I click on the 'Network' icon on the top right portion of the panel, it shows that 'autoeth0' is connected but when I open firefox and try to open any website, the 'Server not found' comes up on the firefox window. Thus I'm not able to surf the web.

I am running CentOS release 5.6 (Final) and have successfully installed PPTPD and this works great internally.
I want to access my Linux box remotely on the internet via my VPN tunnel. However I am not sure what I need to do on the Linux box to make this happen. My linux box is multihomed as follows
PSTN WWW <===========> ADSL Router Firewall <----------------> [eth1 192.168.x.x] Linux Box [eth0 172.16.x.x] <-----> to LAN
The desired topology is as shown.
VPN Client <------> Home ADSL Router <======= PSTN WWW =======> ADSL Router <------> eth1 Linux Box
1. The VPN is setup and bound to eth1 and eth0 and works well internally
2. IPSec, GRE and PPTP rules have been declared on the router which port map to eth1
However I am still unable to setup a VPN connection to Linux Box I suspect something hasn't been done or I have setup my NATing or IPTables correctly on the linux box.

I have just installed Fedora 10. After the installation I was able browse the Internet. However, I did a update: yum update and downloaded 287 updates. However, when I rebooted I could no longer connect to the Internet. I went to network manager and looked at the details of my connection. Everything ok there. IP address, DNS, etc. However, I cannot connect. I have windows xp running on the same system. I can still connect, so there is nothing wrong with my Internet connection.I am using Fedora 10 2.6.27.12-170 There is one thing I have noticed when I shutdown is I see this: "Network manager Int PIC disabled" However, this is only displayed for a few seconds before the computer swiches off.

After running a system update, on next boot I was unable to connect to the internet. I am running Fedora 12 KDE 4.4 x86_64 with a dsl connection. Network manager was keeping my ethernet card disabled. If I disabled NM control of the card I could manually enable it and connect to the internet, but on reboot it would be disabled again. I saw that the update did apply to NetworkManager so I did a downgrade. yum downgrade NetworkManager That seems to have fixed the problem.
Here's an interesting thing I noticed. When I did the downgrade, yum wanted to "Install" for dep NetworkManager-glib for the lower version, however didn't do anything to the same file on the latest version. Almost as if it wasn't installed. Now, with the downgraded version as current, yum wants to update both NetworkManager and NetworkManager-glib to the latest version. I couldn't swear to it, but I think the original update to NetworkManager did not include the *-glib dep, but now it does. Maybe that was the problem all along?

I recently installed F13 on my Toshiba Satellite C650. It has a buggy ACPI which no linux distro till date supports. I got that covered though. But my problem is that the ethernet port works only if the kernel is >=2.34. But F13 came with 2.33.
I do not have an access to a wireless network. Please tell me how to update the kernel without connecting to internet directly. I am new to Fedora. I have been using Ubuntu for some time and this can be achived in ubuntu by downloading the DEB packages and dependencies.

Currently I am trying to get some fedora shares to simply connect to each other to access a read-only shared folder on a host machine (no security/encryption even required for these files!). I've tried to get a smb network share going but that didn't work (can't connect with nautilus), I've tried a quick fix with daap and rhythmbox so that they can at least access the music, but rhythmbox fails very miserably trying to connect/create that (and mt-daapd didn't help much) - Basically I get errors saying the host is unreachable.
I haven't even set up a firewall yet for this network and already I'm running into these fundamental problems. Currently I'm using Fedora 15. On a whim I tried the "public" folder and had sharing of the public folder over the network enabled - yep, didn't work (and I certainly didn't expect it to). I would be trying some more advanced CLI stuff, setting up an ssh server or something, but the computer-challenged people who have to access these files just want to be able to click something and have it work.For the operational requirements of this setup, a file synchronisation system would work (although highly inefficient since it would mean gigabytes sent over the network).

I am having some problems with my CentOs 5 install. On Sunday I switched off my PC. I started it again yesterday, but after that no more Internet access and no more network access. When I go to SysTem * Administration - Network I can see what I had before restart. Nothing was changed. When I try to access to Internet, just get "No connection" problem.
When I try to access to the Local network, I CAN see the others pcs connected to the network, but after I click any of them I get a "Can Not see content" message. I really didnt do anything, didnt changed options... nothing... just shut down my pc and started it at next day as usually do. Im searching for info since yesterday and I cant find anything that work.

Why does it seem now I have to reboot after EVERY update ? I have been a Fedora user for YEARS !! I am on Fedora 11. It seems now that I get updates sometimes 3 to 6 times per week and it always has an icon to reboot !! I can't run a stable web server/DNS/email/NAS server if I have to reboot every day !! Why is every update requiring a reboot now ?

I want to have my Fedora 10 computer act as file storage and access it from my Windows computers.
Details:
Fedora 10 box is fully functional and connects to the internet using a wireless card to my Linksys 54G router. I've configured the smb.conf file to workgroup MSHOME, and assigned it an IP of 192.168.1.150. I've also set it to turn on smb at boot. Windows XP Home is hard wired to the same router with the standard Workgroup of MSHOME. Windows is set to obtain IP and DNS automatically. There's another Windows XP Home system that's also wireless on MSHOME that I can interact with fine from the main Windows comp. Ping results to 192.168.1.150 results in Request timed out.

I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?

I just updated from FC 10 to FC 12 via install/upgrade disk, and when re-booted the screen is then black (at the point that it should display logins). I think it may be due to nvidia driver in FC 10 not being upgraded, because I think I compiled it from nvidia rather from yum install. Anybody else have this problem? BTW, it is a dual boot with Win XP, but has never caused a similar problem before.

I am running Fedora 12 32-bit on an Intel Core2 Duo system. I just installed some recent updated, and after starting the computer, I no longer have any network access, either to my local network or the Internet.
I'm not sure what information to provide at the moment that will be helpful in diagnosing this problem.
What do people know about how I can restore network connectivity to my computer?

I set up a mail server today. Everything works except I can't access the damn squirrelmail web interface from the internet.
I followed this guide here: [URL]
I can access http://192.168.0.50/squirrelmail just fine from a computer on my local network.
*BUT*
When I access http://mywanip/squirrelmail, i get a connection timeout.
When I access http://mywanip, I get the standard Apache "IT WORKS!" Page. (Rules out port forwarding)
According to the guide, that should allow me to access squirrelmail from the internet on my server. Its as if Squirrelmail is only available on my local interface and not on my wan interface? How do I check?

On computer, I have apache server, configured at port 80, running. In local network, web page is accessible by my local IP (192...). Although, when I want to get to the page from the internet, I don't know right ip address, since router's one should be local, and also, router has it's own web page running at port 80. So I guessed that my server IP would be modem's one, which I don't know. Sometime in past, I figured out address of modem too, but it has it's own application running. Also, router supports port forwarding (which I guess, is needed), but I don't know how to get using to it. what address from internet should I have? How should I determine it?

I just got an update that installed, and after a reboot I've got one core at 100%. The "you need to restart" icon in the notification tray said "glibc glibc glibc glibc nscd". Now that I look at it, It's switching between both cored. This behavior is consistent over multiple full reboots as well as kexec reboots.
Edit: Strange, just when I finished, the CPU load settled out and now everything is fine. I wonder what was going on. I'm rebooting right now to double check. Edit2: Yep, same issue 100% usage on one core. And it probably will level out soon. I'm not sure what could be causing this. I assume that glibc could be the issue.

I have windows 7 and ubuntu on same machine, it's Acer aspire 7736. First it was just the 7, then i installed ubuntu 10.10 beta, then updated a month before this moment and never use it sins yesterday. Everything was working fine, i just cant get the sound to work, but this is another thing. When i ran the Ubuntu yesterday the updates was unable to install, Firefox is not working(waiting for google.com, for example), but i can log in to skype with no problem at all, the torrents are working great...
HTML Code:
This is from windows 7 local internet connections.
On default, before i do anything on the network in ubuntu it was Automatic DHCP.
I have router, but i never had to do any manual adjustments on windows or ubuntu before. They just found my internet connection and everything worked great. I use cable internet.

After running a large update and rebooting a few weeks ago, I found that my internet connection had stopped working. My internal network still worked fine though, so it I know it's not the card itself or its configuration. After a bit of trial and error I discovered that simply running dhclient brings the connection up again, so it appears that something is interfering with the initial dhcp update to my ISP (or something like that; I'm no expert in this area. ) My usual policy in cases like this is to wait through two or three updates in the hopes that it's just a temporary problem, but it's been a while now and subsequent updates haven't fixed it.
I've tried looking around, but I can't come up with search criteria specific enough to narrow it down to my specific situation. I'm not even sure where to begin looking to diagnose the problem, nor do I know which package update(s) could've affected it. I'm not sure what might be useful, but here's the relevant entry in /etc/network/interfaces. I have it configured with a static internal address, with my router as the gateway.
Code:
# The primary network interface
mapping eth0
script grep
map eth0

After upgrading Jaunty to Karmic internet sharing (iptables) stoped working. Nothing in iptables configuration was changed. Computers behind my ubuntu router can ping it, have access to it (apache, samba, etc.). Only internet isnt forwarding. Clients configuration is the same as before upgrade.

I've been connecting to the Internet via Ubuntu 8.10 on my Toshiba laptop fine for ages now, but today it has stopped working. Yesterday an update came through relating to DHCP and, like all other updates, I installed it. And now my laptop can see the wireless router but it cannot connect to the Internet. (As I always install the recommended Ubuntu updates I didn't look closely at exactly what the update said, but I did see DHCP in the title, so this is why I suspect my connection is now broken.) Or can anyone tell me how to undo yesterday's update? I really wish now that Ubuntu had a utility similar to Windows System Restore.

The server connects fine, I can load pages, FTP in, etc. So everything seems good on that end. When I try to use the internet from the Ubuntu box, however, it doesn't seem to want to connect. The internet won't load through firefox, and attempting to update through the repository won't connect. I've tried playing around with refreshing the connection and rebooting and such, but nothing seems to be fixing this. I can't think of what the issue may be as the connection is working, as I can get on the server, but can't seem to get it to connect outward from the actual box.

i'm realatively new to linux am just getting my head around the command line, any way my problem today is, my network connection and networkmanger program have been deleted/uninstalled after i did a system update. im running ubuntu 10.04 32 bit. I have run of some commands which should be able to tell you whats going on. at the moment i'm using a live ubuntu cd to gain net access.
so the question is How do i restore my network connection and get my networkmanager program back without a internet connection. (i can download stuff to a memory stick and do manual install) Hope someone can shed some light on this, i know this topic has been covered before although each case seems slightly different to mine.

I plan to install F12 (Fedora-12-i386DVD.iso) in a location where there's no Internet connection, thus I'd like to previously download the updates in order to install them once completed the installation. How can i perform this ? can I download the updates that were released after F12 launch date from somewhere ? how should I tell yum or rpm to find them ?

I just installed fedora on a customers laptop of mine and just trying to get everything working. I hooked up a wireless PCMCIA linksys card and got connected to my wireless and went through the first 250+ updates, all that went fine, so I know I am getting internet access. Everytime I open firefox though I cannot connect to any websites, like I said I am a noob so my troubleshooting skills are very limited with linux, anything I can try etc.

I posted this already in the absolute beginner section, but no answer was found, so I thought I might try this place..Long story as short as possible:
- I installed Ubuntu 9.10 for a friend who was fed up with WinXP crashing all the time
- After the install, networks was broken. I could ping sites outside the LAN, could connect to the router via firefox, but NO application could access the web. - The router works just fine, I tried with my own notebook.
- Disabling ipv6 in grub (edit /etc/default/grub and 'sudo update-grub') seemed to solve the problem.
- Then update the standard packages + install restricted extras and boom, Network gone: No ping to sites outside the LAN, no nothing. Still can connect fine to the router and even the remote desktop connection works, connecting over the internet. But that's it.
I have tried setting the mpu to a value recommended by my isp, I have set static ip and dns, I really don't now what to try any more.
