Fedora Networking :: Dhclint Wlan0 Fails Since 2.6.27.19-170.2.35.fc10.x86_64
Mar 16, 2009
Since 2.6.27.19-170.2.35.fc10.x86_64, dhclient wlan0 doesn't seem to work any more.
However, bizarrely, dhclient eth0 does (to the same D-link wireless router).
The AP shows connected - tail /var/log/messages
No working leases in persistent database - sleeping.
WINXP connects just fine. This (B43) has worked nicely ever since FC10 came out, and I was able to use the WiFi at all kinds of places on a recent trip. Other than a couple of yum updates, I don't think anything else has changed since. Other devices on the wlan are getting their DHCP requests satisfied correctly.
Is anyone else having this problem since about a week ago? Perhaps there's something really obvious I'm missing. I can manually assign an IP address to wlan0, manually edit the routing tables and edit /etc/resolv.conf, and then Wifi seems to work OK, so it doesn't seem to be b43 itself unless it is dropping DHCPOFFERS. If this isn't a regression, does anyone have any tips about how to debug this?

I recently upgraded my x86_64 system from FC8 to FC10 using Pre-Upgrade. (related blog link) It appears that the upgrade process installed a steaming pile of i386 packages that are duplicates of existing x86_64 packages. I now get update errors because of this package clash. I have searched the fora and the most progress I've been able to make so far is: I apparently had 8 unfinished yum transactions so I did yum-complete-transaction 8 times and have no more incomplete transactions.
The output of package-cleanup --dupes is not very helpful:
Code:
[tim@servy ~]$ sudo package-cleanup --dupes
Setting up yum
Loaded plugins: refresh-packagekit
Yet I still get transaction errors when I run updates via synaptic. It checks dependencies and downloads everything and errs when testing changes. This is the error it gives at the moment:
Code:
Test Transaction Errors: file /etc/gconf/schemas/gweather.schemas from install of libgweather-2.24.2-1.fc10.x86_64 conflicts with file from package gnome-applets-1:2.20.1-1.fc8.i386

When I try to bring up my wi-fi PCI card (ifup wlan0 or ifconfig wlan0 up) my whole PC just hangs until I power it off.
I believe I have the right drivers, but cannot see what I am doing wrong.
I'd really prefer not to go down the ndiswrapper route.
Firstly, I can see the PCI card and the driver it is using :
Code:
[J@gx260-f10 ~]$ lspci -k
...
...
01:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller (rev 20)
[Code]....
the PC just hangs for ever. No mouse movement, ctrl-alt-del, nothing.
I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.

I have fedora 10 installed and when my monitor is turned off the X session fails to start because it can not probe for settings. Is there a way to hard code the settings for x instead of letting them assign dynamically on boot?

After "yum install emacs" & "yum install emacs-ess", I was able to install emacs on my X86_64 running Fedora 10.
If I run one session of emacs everything works fine.
Once I start a second session and try to resize or move the emacs window, the system stops responding.

I'm I seeing this wrong or is the initrd file in kernel-2.6.27.25-170.2.72.fc10.x86_64 a zero byte file and that's why I can't boot with it( get this "kernel panic not syncing VFS unable to mount root fs on known -block (0,0)" message)

I just tried to update to kernel 2.6.27.15-170.2.24.fc10 (x86_64) at the suggestion of the gnome update widget, and the process hung. A bunch of other things were updating at the same time, many of which were related to audacity or wine.
I'm not sure just what was being updated, because the option to review which updates are available does not work - when I click on it, nothing happens, but when I take the other choice (install all updates), I take pot luck. It would be nice to be able to choose which programs to update, and to be able to upgrade the kernel independently, but I don't seem to be able to do that at the moment.

Here's the deal: I had a nice little fileserver running under 2.6.27.21-170.2.56.fc10.x86_64.
3 disks in raid 5 ext4fs, then I thought..."hey I'm a greedy bastard..I want another drive!!
So I get it..do a normal mdadm --grow...after around 1100 minutes .. FINISHED!..whee..happy...
I decide to do a upgrade to 2.6.29.2-52.fc10.x86_64 to get the fix for growing the ext4..
reboot...
Code:
md: bind<sda3>
md: sdc3 has same UUID but different superblock to sda3
md: sdc3 has different UUID to sda3
md: export_rdev(sdc3)
md: sdd3 has same UUID but different superblock to sda3

Epson R285, good as gold on FC14, and intially onFC15. Entering the cups admin tool, localhost:631, the printer is set up, the correct drivers are slected, paper size OK.
Cant get it to print a test page, its wants the password for CUPS and wont accept root, but root login can change all other params.
On the gnome printer applet , you can unlock it, add printer select local, and it goes away and finds the Epson R285, click on "add" it queries the printer and immediately drops back to the original printer applet. Without adding a printer. I haven't succeeded with network printing, the firewall is open on port 631, yet any attempt to find it from another computer fails. The gnome printer appet which interfaced with Gnome 2.x was nice, you could select everything needed. Not with this thing.

I'm currently running FC9 and I have no problem with my network connection. Now I just installed FC10 on another partition too try it out, but I don't seem to get it work. I disabled the NetworkManager (like in FC9) and enabled the Network. I'm using static IP, when in go in Network Configuration/Ethernet Device/General, the subnet mask is always taking the address of the Default gateway address when I press OK.
my subnet mask is 255.255.255.0, and my gateway is 192.168.1.1, but after I press ok they both go back to 192.168.1.1

I and my friend use FC10 on our laptops. We want to share our data by creating a wired network between our machines because a wireless router is something what our pockets can't afford. What should I do for it? What type of wires and stuffs do I need? I Googled for some link for doing so in FC10 but couldn't find.

I recently upgraded my x86_64 system from FC8-FC10 using Pre-Upgrade, and here I got some help fixing all the package conflicts that resulted. Following the first reboot after this massive package update, it appears DNS doesn't work in some apps.
I could ping www.yahoo.com, and nslookup www.yahoo.com resolved the name, but firefox and links couldn't. Typing the ip addr that nslookup gives for www.yahoo.com works fine in both firefox and links. Something's obviously wrong with DNS.
I found a workaround for Firefox which is to browse to about:config and set network.dns.disableipv6 = true. Firefox started resolving names after that.
But then I noticed yum is DNS incapable as well. I don't know how to fix it. Here's what I get:
Code:
[~]$ sudo yum update
Loaded plugins: allowdowngrade, refresh-packagekit
http://linuxdownload.adobe.com/linux/i386/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Trying other mirror.
[Code]....
Does anyone have any additional info on workarounds or fixes for this DNS problem?
The machine in question has a static ip addr, and I have static nameserver addrs in /etc/resolv.conf, corresponding to the static settings provided by my isp.

I'm bonding the two NICs on my FC10 server to create a bonded LAG between it and my Cisco Catalyst switch, but during kernel init, the system always give me a notice that "bond0 doesn't appear to exist" so it skips it.Once I log in, I can always open Network Manager and the bond0 interface goes from "Inactive" to "Active" and bond0 immediately works, and I can restart the appropriate network services and everything is fine. But any idea why this bonding wouldn't be initializing during boot up? The ports on the Cisco are configured for hard set speed and duplex and portfast is turned off on them.Is there a guide for best practices for creating LAGs (bonded interfaces) between FC10 and Cisco switches?

The past couple days I've been attempting to use ndiswrapper to connect to my home network wirelessly and have run into a slight problem. I'm able to install ndiswrapper (of course), and install the driver. ndiswrapper -l comes up good, showing the driver is in place for my netgear wg311v3 card.
modprobe ndiswrapper I am able to get to work without errors, except, when i type ndiswrapper -ma it writes another file to /etc/modeprobe.d/ndiswrapper causing the deprecation error.
The card scans for networks, and I'm able type in my encryption key.
However it doesn't connect. | grep comes up with the error that the wlan0 link is not ready.
I think I've also been able to determine that the configuration I've put in to the card through the network manager is not actually configured.
Anyone know how I could possibly connect with the card.. It seems it should be able to work. alias wlano is also in place.

We need to have the wireless associated with the access point prior to the first login.
Have not been able to get it to work yet. WPA-PSK. wireless will not connect until login.
This is necessary for nfs automount and openldap auth to work. Not a home networking environment.
How to troubleshoot effectively.

I've been able to get a laptop on Fedora 14 (2.6.35.6-48) working with a Netgear WNA1100 Once up and running, I execute "ifconfig wlan0 up" from root, and everything connects just fine and is stable as long as I stay logged in. But, I haven't found how to do this automatically on boot.
I've tried to use NetworkManager, but I cannot figure out how to get the GUI to show up - it says its running and enabled in the Services gui, but I haven't figured out how to actually use it! I checked to see if the nm-applet is running with ps, and for the user login, I see:
I'm not sure if the "sm-disable" flag is my problem, or how to change it. I'm not even sure if NetworkManager will allow me to set things up for bootup, but that is the path I ran down...
I assume this is a fundamentally easy process to set this up on bootup, but I'm not stumbling across the method. I recall doing this kind of thing years ago when I was an engineer, and before I got my lobotomy to become a manager...

my eth0 suddenly stopped working on FC10. i have been using it the whole time, and now it refuses to even ping the gateway. dhclient is not receiving a dhcp offer and when i put in the information manually, it is not even able to ping the gateway. netstat -rn shows that the destination of the router is going nowhere.
i do not think it is the hardware/software, but rather maybe the provider? i am from central europe but just moved up to great britain and working at a friends place. i can connect the mac powerbook without a problem (it will get an ip with dhcp), but not the linux machine.it is a normal ethernet modem connection here. can it be, that it checks MAC addresses or even the computer names? the powerbook also has a really weired IP address: 77.102.xxxxx
i am not using network manager, but command line tools and have nm uninstalled. does anyone have a clue, what this could be about? i am not a newbie, but this is really puzzling me.....

I would like to mount a bunch of folders/shares when I start my machine up. I will be adding the mounts into my /etc/fstab folder BUT my WLAN0 only comes "up" and connects to my WAP AFTER logging in.
how I get it to start on PC boot instead of log in?
I think I need to disable network manager but I'm unfamiliar with the procedure in Fedora

I am having a problem trying to transfer large file (~700MB) from one station in my home to another. I have 3 PCs hooked up through a router. 1 is wired to the router and the other two are wireless. One wireless is a laptop that has a built-in Atheros wireless card that was supported during the FC13 install. The other wireless has a plug-in wireless card made by Belkin (F7D1101). I had to use ndiswrapper to get it to work on FC13.(BTW all PCs are running FC13)
The one with the Belkin card is, I think, the problem. The one with the Atheros card will transfer files at a rate of about 8MB/sec to the one with the wired ethernet connection. The one with the Belkin card will not transfer at rates over 300KB/sec to either of the other two PCs. I have tried file transfers both encrypted and not and it makes no difference.

No wireless card show up in the wireless tab of Network Manager. How can I fix this since my card is listed in ifconfig and iwconfig. Wifi card is a Zonet zew2500p
