CentOS 5 Networking :: Determining IP Information For Wlan0...SIOCSIFFLAGS: No Such File Or Directory
Oct 18, 2009
i wanted to learn linux, so i just installed Centos on a thinkpad x200. my wireless will not work. when i try to activate it i get this error:
Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory
SIOCSIFFLAGS: No such file or directory
# lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.
Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data
I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
how to make intel 3945 to work on RHEL5 ? Apparently that hardware is not officially supported by Red Hat so they do not provide drivers. what happens on my PC is after login I do not have the wireless card led is off and when I try to start the wireless connection I get
SIOCSIFFLAGS: No such file or directory
I'm not a real linux expert but I do use it since long time.
I can't seem to figure out how to solve my problem. I have a HP Mini 1100 and I can't seem to get wireless working. As the title says, when I type ifconfig wlan0 up I get the SIOCSIFFLAG: No such file or directory error. wlan0 is listed in the output of ifconfig -all. Here is the output of lspci and lsmod:
* ifconfig wlan0 up * iwconfig wlan0 essid 'XXX' * iwconfig wlan0 key XXXXXXX * dhclient wlan0 -> here i get error: ls: cannot access /var/run/netconfig//wlan0/: no such file or directory
Running CentOS5.4 on home-build.The wireless card setup is working,at least with regard to internet access through a Linksys router.Trying to set up Windows shares using SAMBA has been problemmatic. After many searches the ifcfg file seems to be a mystery. So what is meant by the "ADDRESS0=" in the ifcfg-wlan0 file. it is the ""the NETWORK that matches the NETMASK". But even that I cannot quite understand (apparently) as my efforts to enter different items in this file have all failed.

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 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.
I have managed to configure a wireles PCI card on CentOS 5.3 and it seems to work fine. It is a off brand (Hercules) with a Ralink RT61 chipset. I installed the most current driver (RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) from the rt2x00 Open Source Project. I now have a question that might be very simple for one or more of you to answer. When I issue the command "shutdown -h now", the machine starts to come down and brings down eth0 cleanly, but when it attempts to bring down wlan0, the machine hangs and never brings down the interface OR powers off the box. The only way to complete the power off is to "hard" power off the machine.
I have a desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.
When I attempt to add software i get the following error:
Unable to Retrieve Software Information
This could be caused by not having available connection.
Cannot find a valid baseurl for repo: addons
To get my browser to work properly, I have to specify a proxy (manual) and use the IP address of our proxy server. After this, I'm able to get out through the internet using my browser. Not sure why I fail to get software updates though. I used the same setting in Proxy - Control Center. Repository Manager show's CentOS-5 - Addons mirror list as :

Looking at the output of netstat, I'm not seeing a definitive way to tell which torrent connections are clients reaching in to my machine vs my machine reaching out to the world. Is there a clear way to determine which is which?
i've configured my laptop so i can use my domain account (active directory win 2003 DC) to logon to my machine. Now i'd like to browse and mount shares etc using my logon information. Now when i connect to a share with nautilus it tells me 'guest' can't log in and i need to re-enter my user info. This is a real pain since our passwords change often. Is there some way i can use PAM to authenticate? I've searched everywhere, but you only find info about the other way round (win->linux).
I am trying to remember the procedure used to determine the ip address range when given a network address and its subnet mask. Does anyone have any documentation on the steps that are done to accomplish this?
I have two NIC cards installed, they both go to seperate networks. Occassionally I am not able to establish a connection via eth1. When looking at tcpdump traces I see that Linux is using eth0 hardware port and putting eth1's IP address in the packet to reply to the connection request. When the connections work its when Linux uses eth1's port.
All routing settings made with the ip tool (route command) are lost when the redhat server reboots.How to save routing information to a configuration file?
Im new in centos community and i just installed it.I installed it through the virtualbox and without X server so i im running only with console. I have problem with ssh keygen. When i generated a keygen i get two files: keygen and keygen.pub. Tutorials telling me that i have to rename keygen.pub to "authorized_keys" and copy it to /root/.ssh. But when im trying cd to /root/.ssh then i get the error: no such file or directory, even "whereis" don't know where is this folder.
I upgraded my php from 5.1.6 to 5.2.10 but at php -v I got a weird error, so I figured let's reinstall some things. This was the probably very dumb commando I used:
yum remove gcc-c++l zlib zlib-devel php*
Now I think my whole server is fxxxed because I get the following messages:
-bash: /usr/bin/yum: No such file or directory -bash: rpm: command not found -bash: ls: command not found
And the only thing I'm glad about is I still have an SSH connection open because creating a new connection isn't possible either. what should I do to repair this all.
CentOS 5.4 (Final) is installed on my VPS.I'd uploaded a zip file that contains a directory and some files that there are space in their names and now I can't do anything with them.
I am running WHM and CPANEL on centos.I would like to upload a file to the root user directory. To be honest, my only experience uploading and downloading files with FTP has been with domain related accounts that were set up under WHM to be managed under CPANEL. This is quite simple, because all you do is set FileZilla or Dreamweaver up with the FTP address of the domain account and the username and password.How can I do something similar to FTP a file into the root or home directory?
