CentOS 5 Networking :: Rt61 PCI Wireless: Freeze Upon Shutdown With Static IP Configuration
Jun 24, 2009
I have one desktop PC I'd like to use as a jukebox. It's installed in the basement as a black box, with only SSH access, and it has got a minimal CentOS 5.3 install with MPD and NCMPC. It's connected to the hi-fi in the basement, so I can stream music to it when I'm downstairs. Since I didn't want to use cables everywhere, I bought a PCI wireless card, with a RT2561 chip.
Until recently this card worked OK with Linux. Recent kernel version even have out-of-the-box support for it, except of course you still have to download the firmware from the Ralinktech website.
I gave the thing a static IP configuration by editing /etc/sysconfig/network-scripts/ifcfg-wlan0, interface went up fine, I can ping the machine and SSH into it OK. Now the only problem is, when I do a shutdown -h now, the machine "hangs" while trying to bring wlan0 down. (In case you wonder: I temporarily attached a monitor to it, since wanting to know what goes on while shutting down in an SSH session is a chicken-and-egg situation :)). I actually have to hard-reboot it (by pressing RESET).
I have strange behaviour on my portable computer Asus UX30. I'm using latest Ubuntu 10.10 release. The main problem, and the most annoying, is a system freeze on shutdown, suspend, hibernate or even restart. For a week I'm trying to find a solution on the web, but no result. From what I noticed, computer freezes when a wireless card is turned off or on. Here are some basic info from wireless card:
I have a CentOS5 server with dual ethernet adapters + Webmin installed as my Router / Firewall / DHCP server working successfully with 1 static IP from my ISP. I also have 7 additional static IP addresses from my ISP needing to configure to individual servers inside my network. I have configured the additional virtual interfaces, but am lost on how to route data specifically from additional ISP address to specific internal network address.
Below is my desired configuration. 98.173.159.xx1 = eth0 physical interface ==> eth1 192.168.1.1 98.173.159.xx2 = eth0:1 virtual interface ==> 192.168.1.10 ==> CentOS Server 2 98.173.159.xx3 = eth0:2 virtual interface ==> 192.168.1.20 ==> CentOS Server 3 98.173.159.xx4 = eth0:3 virtual interface ==> 192.168.1.30 ==> CentOS Server 4 98.173.159.xx5 = eth0:4 virtual interface ==> 192.168.1.40 ==> Mac OS X Server 1 98.173.159.xx6 = eth0:5 virtual interface ==> 192.168.1.50 ==> Mac OS X Server 1 98.173.159.xx7 = eth0:6 virtual interface ==> 192.168.1.60 ==> Network Attached Storage Server 1 98.173.159.xx8 = eth0:7 virtual interface ==> 192.168.1.70 ==> Windows 2008 Server 1
I'm having trouble installing my RaLink RT2561/RT61 wireless card. It seems that this driver causes problems for all ubuntu users, and I've tried a couple of work arounds, none of which work for me.
Firstly I downloaded the most recent driver from here: [URL]...RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) is the driver I downloaded. Next I performed the following steps: Code: robinsjp@home-desktop:~$ sudo apt-get install linux-headers-`uname -r` build-essential gcc Reading package lists... Done Building dependency tree
I have just purchased an Edimax EW-7128g with Ralink RT61 chip and physically installed it in a system running CentOS 5.2. Trying to follow the installation instructions, I get the following:
[root@webtest Module]# make all make -C /lib/modules/2.6.18-92.el5/build SUBDIRS=/root/drivers/2007_1210_RT61_Linux_STA_v1.1.2.0/Module modules make: *** /lib/modules/2.6.18-92.el5/build: No such file or directory. Stop. make: *** [all] Error 2
The problem is that although /lib/modules/2.6.18-92.el5/build exists, it appears to be a link:
[root@webtest Module]# ls -l /lib/modules/2.6.18-92.el5/build lrwxrwxrwx 1 root root 43 Mar 23 15:34 /lib/modules/2.6.18-92.el5/build -> ../../../usr/src/kernels/2.6.18-92.el5-i686
Just installed Ubuntu Studio 10.04 and everything seems to be working nicely except I have no networking.
The card does not appear in the Network Settings GUI. The only 3 tabs I have are General, DNS, and Hosts.
A screen grab is attached.
I'm a long time Windows user trying out some of the best Linux creative apps I can find. So, Ubuntu Studio was a no brainer. I checked the manufacturer's site for linux drivers and they are available, but I don't know how current. (Edimax site, not RaLink's site.) I opened the file and it looks like it needs to be compiled and installed to work. Something I know almost nothing about. The card is listed as supported in this forum for Ubuntu 9x but I can't find information about it for 10.04
PS. I have no networking on the system but I can transfer files via USB flash drives if needed.

I have recently installed CentOS 5.3 in my system. I needed some help with the wireless configuration. Actually i have configured it and it shows the wireless name but it doesnt connect to it. in solving the issue.In the /var/log/messages , the following error appears :
Running Lucid 10.04 in place of XP on my old Packard Bell Imedia has been good apart from the random freeze-ups that often prevent booting or stall the shutdown process. Today I think I solved it!? It appears that my wireless PCI adapter (ZyXel G-302 v3) was causing the problem. Ubuntu had installed a default driver which seemed to work OK; but I thought I'd try installing the Windows XP driver from my original ZyXel install disk as an experiment. I used ndiswrapper, got the XP driver installed and my freeze-ups have gone (touch wood).
The wireless network on my laptop is configured with a static IP. (not using nm). When I take the laptop out of the range of my wireless router the essid is becoming off/any therefore when I'm back in range the connection is not reestablished and to re-enable the connection I gotta do "iwconfig wlan0 essid <essid name>" otherwise there is no connection. Make sure that essid stays configured unless I manually want to change it?
About a year ago I had a different computer with this same wireless card (edimax EW-7128g) and it was recognized immediately after I installed ubuntu 8.10. I found this hardware compatibility page, and it says it is compatible, at least on 9.04.
After reading this old guide I found:[URL].. I downloaded the latest driver, and followed the instructions (i had to refer to the readme too, some things were slightly different which I'm assuming is because it's the 2010 driver not the version referred to in that tutorial) up until:
(e) copy the rt61.ko driver file to the modules directory then load it Code: $ sudo cp rt61.ko /lib/modules/`uname -r`/kernel/drivers/net/. $ sudo depmod $ sudo modprobe rt61
I don't see where rt61.ko is.I've got the information for my wireless connection edited into /etc/Wireless/RT61STA/ rt61sta.dat iwconfig shows pretty much default stuff, no mention of my wireless card or any type of connection, though the card does show up at the bottom of the lspci query. I added the wireless connection information into the "Network Connections" prompt in the preferences, but obviously that's not accomplished much of anything for obvious reasons. Should I just install 9.04? Judging from this account, getting this wireless card to work would be a hell of a lot easier.
how to set up a static IP from Ubuntu... Secondly, on some of the tutorials I read, there was something about changing the DNS server IP adresses. I do know what a DNS server is (Courtesy of www.howstuffworks.com ) but I don't understand why the DNS servers must be changed simply because I chose to use a static IP address.. (My PC connects to the internet via a router.. )
I am a developer, not a network admin - sorry if this ia dumb question. I need to test an application on CentOS 55 64 bit. The instalation went fine and initially I let DHCP work its magic. The router IP address ia 192.168.0.1 and all other VM's I have are granted dynamic ip address on this range (i.e. 192.168.0.x). However, the CentOS vm got an IP address that looks like it belongs on a different subnet :192.168.1.1
The VM (vmware desktop) network setting for this VM uses "Bridged: Connected directly to the physical network". I can ping the host (Windows 7 64 bit) and the host can ping it (it been the VM) - but no other computer on the network can see it. To make things easier, I changed the network configuration to use a static IP address. Here are my configuration files:
Debian Testing host, Winduhs XP guest. Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).
Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.
I have been googleing for the last hour and a half trying to find the easiest way to set up a static IP for my laptop's wireless connection.The most promising link I found required me to delete the network manager but I do not want to do this as I often take my laptop with me so I need to be able to connect to new wlan easily. I just want a static IP so I can set up port forwarding.Is there a equivalent process to windows XP where you just manually assign a local address like 192.168.2.9 or something like that? I tried setting it up through the network manager but later read that it doesn't work for encrypted connections.
I'll be frank. I recently switched to Ubuntu 10.10 to become more familiar with linux as I set up a website, but I'm also an avid user in a private torrent tracker. Coming from windows to linux, I don't know how to properly set up a static IP address from my wirelessly connected laptop. Other walk-throughs for setting up a static IP seem to focus on desktop machines and not a wirelessly connection machine. These walk-throughs also tell me to delete Network manager, which really messes up the ability to find connections for a wireless laptop. I also have two homes I go back and forth with, so I'd simply like the ability to just emit a static IP, and for my main networks to allow me to connect, and upload/download from it easily.
I want my Ubuntu desktop to have a static ip-address, i have altered the interfaces file to the below and also filled the info regarding my wireless network card but still every time I reboot the desktop gets the ip 10.42.43.1, HOW is that possible???
I use a apple time capsule router, I want my desktop to run a apache server thats why I need the static ip. I also want the static ip to be set on the wireless network interface. I have an old laptop with an internal Intel pro 2200 card so there should not be a driver problem.
This i my interfaces config code...
To be on the sure side to get this to work I have configured my router(DHCP) to give my wireless-HWaddress the ip of 10.0.1.15, STILL the ubuntu desktop starts with the false address above.
I want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4 IP Address: 192.168.1.6 (This is the item I wanted to change and make static) Broadcast Address: 192.168.1.255 Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections" 3. I selected the wireless tab and then the wireless network I wanted to edit 4. I clicked on the edit button and then I clicked on the IPv4 settings tab. 5. I changed method from Automatic (DHCP) to Manual
I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).
I've installed Centos 5 on 2 serveurs.The first one export the file system with NFS.The second one use amd to automount the filesystem with the link/net/@IP/Shared/folder/On the client side, I mean the second server, there is some logs into the messages system telling us the the process gam_server as crashed (segfault)On the first one, sometime, NFS Freeze, and nothing is available. This need a Hard reboot of the server in that case.
I have read this: [URL] I have been trying to set a static IP address for my Dell XPS 8100. It has a wired and wireless connection. DHCP worked fine for both of them. My goal is to set up Samba and some other things that require a static IP. My /etc/network/interfaces file looks like this:
[Code]....
If I take the eth0 interface down, I can connect to the internet sudo ifconfig eth0 192.168.1.154 down Which is really puzzling because I think that I am setting both interfaces in the exact same way. What am I missing?
I've a damn TP-LINK WG422G UBS Adapter that i love i installed latest compat-wireless driver package and used latest ar9271 firmware after that it was worked properly. There is no problem when surfing the net, the problem is occurring usually download something via torrent sometimes form websites. I'm starting to download and then usb adapter suddenly freeze. If i remove and plug in the usb adapter it is working again.
Ubuntu boots fine with wireless turned off via the laptop wireless button on the case, and fine with wireless on but no networks remembered, but as soon as I try to connect to a network, I get the strobing wireless icon in the top panel and then the whole system freezes. It switches to a black screen with a non-flashing terminal cursor in the top left corner of the screen plus a frozen mouse pointer in the last position from when Ubuntu was working. If I force a power-off after this, which I have to, then unless I manually turn off wifi using the laptop button then Ubuntu never boots and I just get a black screen after the BIOS screen. I can connect to the internet via wired connection.
i am running ubuntu netbook 10.10 and i am having the problem where on shutdown it just freezes. i have read a lot of people are having similar problem.i noticed there are 200MB of updates on my system that are yet to be installed, so i thought i would try installing them first to see if it fixed the issue.the problem i am having is, when i go to install the updates it says that it cannot install, check your internet connection. my internet connection is fine, i can browse to websites etc. and i have tried both wireless and ethernet, doing same thing. i also restarted several times.
I decided to take the plunge and change the existing static ip configuration for my home network to a dynamic (DHCP) configuration. The DHCP server in this new network config is my gt701-wg actiontec DSL modem.
I am having several boxex with centos on it. No pb. I have recently setup a new box with centos 5.4 and I am not able to get the network working on it when configuring a static ip.I've configured eth0 and dns using "setup": unsuccessfulI've used the network config GUI: unsuccessfulAnd it is working very well when I let the dhcp getting the setting.I need a static IP.Here is the getinfo output when static ip setup, and below it, the getinfo for dhcp setting
== BEGIN uname -rmi == 2.6.18-194.3.1.el5 i686 i386 == END uname -rmi ==
I had something I think if very odd happen to one of my computers at work today, it appears to have spontaneously switched from having a static address set to getting its address by dhcp.this is a small office with a mix of mostly linux servers and desktops with a few stand alone windows computers, mostly notebooks. Most of the desktop computers get their address by dhcp, they all have NIS /NFS for remote mounted home directories (interchangeable desktops so anyone can log in at any desk). The particular desktop computer in question here has a shared printer on its parallel port, so has a static IP. Yesterday a UPS in the server rack died, after pulling it and plugging things back in and restarting the servers, it was easiest just to reboot all the desktops, everything came up ok including the desktop in question, and the printer did work.
Today I pulled the oversized UPS from this desktop to replace the dead one, and put a more appropriately sized one in its place, shut the servers down again, rebooted, etc,About an hour later someone tells me the printer is not working on the desktop, and after a lot of searching I find this desktop has the wrong IP address, I ran system-config-network and it showed the address was set to dhcp, I changed this back to the correct static IP and things seem to be working ok now.
After upgrading one of my computers to 10.10 I experience freeze on shutdown I understand that there are multiple things that can do that. Is there a way to Isolate the issue. It freezes during the ubuntu dots screen. The dots are still changing endlessly. So it is not complete freeze. The only way to intervene is by issuing a CTRL-ALT-DEL then the computer restarts.
