I have installed CentOS 5.6 X64 on my laptop ASSUS. I can't configure ethernet card. I saw the card listed in the lspci but not under ifconfig -a. From dmesg we can see that the driver is loaded.
I have a server that is on both a standard network and a virtual network, as follows: server1 attached to standard network server1 acting as Dom0 with two linux DomU guests (under Xen) I only have one network card. How do I configure server1 to have a different hostname on the standard network than on the virtual network? Here are the relevant network configuration files for server1:
I am attempting to setup a network to network VPN tunnel between our main office and a temporary location. This location need full VPN access back to the main office's network.Anyhow we have spent about 3 solid days attempting to make this work without any great success. Here is our network scheme for these two devices.
Network A (Main Office) (OpenBSD using isakmpd) Network: 172.16.8.0/24 External IP: 1.1.1.1 (obviously not the real IP)[code].....
I just have CentOS installed and cannot get the Agere et131x network card to work.I have tried the following:Reboot the computer and still did not see the network hardware.
I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.
I'm in a research institution with about 20 linux desktops currently running different versions of fedora. The sysadmins used to update and configure each of these machines individually. We want to move to centos to make operating systems more uniform and simplify administration.
The basic needs are: One central, easy-to-use package management for all machines central management of configuration files for all machines. In addition it would be nice to have a local repository with a subset of user-installable rpms. It looks like rhel can do this with the redhat network. Is it possible on centos, too? If yes, is it necessary to pay a subscription to rhn to use their web hosting of services?
I have installation of Xen and Centos 5 (all RPMs are from Centos repositories). I have several DomU virtual machines running on this machine. When I try to copy some bigger amount of data from another physical computer to Dom0/DomU on this machine, the network freezes. The link is still up, I can see that the connection really links on the switch, but nothing is received or sent to the network. I tried to stop all the DomUs, stop the network, unload the network drivers from memory and loading them again and starting the network, but the problem persists. Only reboot solves the problem. Sometimes the amount of data have to be around gigabytes (last time it was 10GB), sometimes 500MB is enough to stop the network... I also tried to change the NIC, but the behavior is the same. Btw. logs don't say anything :-/
PS: this is the output of my lspci:

I intent to develop a centos server with lamp. What I want is connect the server to any kind of home network and access it by hxxp://myserver.
If you had to develop a solution with the intent to plug in the box by Ethernet to a router and access it with a browser using the server name what would you do? That's basically what I'd like to know.
I try to install CentOS 5.3 with DVD. After choosing option for disk format, next step should have been Network configuration (for dynamic or static) but I found no thing. I chech many times but still can not find any steps so that I can configure network before anaconda starts to install CentOS. Note that, I choose option to install from dvd not via network.
I have two CentOS 5.4. One is real/host and the other one in VMware-Server.
IP of host is 192.168.200.0/24 and IP of guest is 192.168.210.0/24
I can use ftp,samba,http .. between them but can't mount nfs in the guest and vice-versa since, they are in different network. showmount -e , shows the nfs shared list
For several months I've been running a Centos 5.3 server on a home network. The server hosts PHP, Postgres and lighttpd and other open source software bundle into a system I call RIMS. PHP, Postgres and lighttpd and other open source software were compiled from tar files. All Windows machines on the network can access RIMS via lighttpd. No special firewall rules are required on the PCs or on the 5.3 server.
With the release of Centos 5.4 I decided to do a major upgrade to MJR and built a new 5.4 server using a minimal install from CD1, with all options deselected. The details of the installation are available at http://pastebin.centos.org/31877. I added gcc, gcc-c++, m4, make, mlocate and vixie-cron using yum, to give me a compiler and a search capability on the new server.
Problem: when I compile and start lighttpd (or nginx or httpd) on the new server none of the Windows PC can connect to the server - they time out waiting for a connection. I didn't discover this until I'd installed a lot of open source software on the server, so I went back and rebuilt the server with only lighttpd on it, but the problem persists.
I thought it might be a firewall or Selinux problem so I compared the Selinux variables on the 5.3 server with those on the 5.4 server and they are basically the same. Setting httpd_can_network_connect on doesn't make any difference. I also compared the iptables script on both servers and they are the same. I've run nmap on the 5.4 server and it shows port 80 is open. The list of installed packages on the 5.4 server is available at [URL]...
I have centos 5.4 with kernel 2.6.18-164.el5, i want know what card for 100mbit or better connection is good solution, some hints for network card? What do u think about this cards?Intel Gigabit CT Desktop bulk - EXPI9301CTBLK or something different for game server?
Often after using the network tool, making changes, saving changes, closing the tool, and running a 'service network restart'; the tool will not open again unless I reboot. This is the case both via System --> Administration --> Network and system-config-network (from the command line). I am in runlevel 5, as an uprivileged user when this happens.
I am attempting to connect a CentOS VMWare VM to a networked Brother HL5170DN printer. The printer is located at 192.168.0.101. It is available and I can connect to it with various Ubuntu and Windoze VMs.
I have searched for instructions on how to do this and it SEEMS rather simple. However, it does not work. Here is what I have done:
System; Administration; Printing to launch the printer configuration wizard supply root password New Printer Provide printer name, description etc. Select Connection - LPD/LPR Host or Printer Hostname - 192.168.0.101 supply a printer name again select Brother HL5170DN BR-Scripts3 from the footmatic database complete creating the printer
The printer appears as a local printer, however, I cannot print a test page. Nothing happens when I click the button to print a test page. I can ping the printer by IP address. So I deleted the printer and tried again.
At the screen which asks for Hostname and Printername I entered the printer's IP address in Hostname as I had done before. I then clicked the Probe button. At this point Printer configuration freezes and I have to do a force quit.
I just tried the same thing on a physical CentOS 5.6 box - just in case the problem was a VMWare thing. Same symptoms. Probe freezes the Printer configuration program. I then recalled that the printer uses port 9100. I opened 9100 on the firewall (I think) but no improvement. I temporarily disabled the firewall and went throug the proces. I now have the printer defined at "socket://192.168.0.101:9100" and recognized as "Brother HL-5170DN BR-Script3"
I still cannot print a test page. I tried to print from gedit and it shows the printer with 1 job in the queue. The gedit print bumped that to 2 jobs in the "printing" state. Looks like I am communicating with the printer. Just not printing.
When CentOS boots up, it tries to determine the IP for a network device (eth0) and fails. 'Determining IP information for eth0... failed; no link present.' I'm curious to know how, after booting up, I could set the IP information for a wireless device, wlan0, manually. Another way of putting this questions is: if CentOS is able to determine IP information for a network device on bootup, what settings is it configuring exactly?
I'm a Linux n00b (very fluent in Windows, though ) that is attempting to set up a (currently) 3-computer cluster. My server node is a Pentium 4, and my client nodes are a Pentium 4 and a Pentium 3 (whatever I have lying around ) I chose to use OSCAR for my clustering interface and CentOS 5 for my server node OS. Yay. I made it through the installation prerequisites, but when it came to configure the NIC, I got stuck.
I opened the /etc/hosts file, tinkered with it, but something inevitably got screwed up. I can still use the Internet, but it won't let me install OSCAR. Running a system-sanity check returns:
All I need to know is what the /etc/hosts file should look like for a CentOS 5.4 installation with 1 NIC that is not connected to a domain (only a LAN). It is connected to a router which in turn is connected to my home network (I don't know what to do about that). The hostname should be surgeonfishr and the IP address should be 192.168.0.150.
I know this question is probably really stupid, but I've logged a total of about 10 hours time on Linux...ever. (And 35000 hours on Windows.)
I am trying to learn about networking and am looking to set up a mini network between three bare bones Centos machines in Virtualbox. I set up the machines with a static IP. In the Virtualbox I am using NAT and have the IPs as follows Centos-1 IP: 10.0.2.15 Gateway: 10.0.2.2 DNS: 10.0.2.3
On all machines i can ping google.com, and yum updates, but I can not ping any other machine. It says they are unreachable. NOt really sure what to do. Any help would be much appreciated.
Installed 5.6 and all is well except my window pc doesn't see the centos laptop on the network, but it is on the network. I have access to the Internet via firefox. Obviously need to set some ipconfig settings, but when I try to edit ipcfg file in sbin, I get a msg, "not the owner, can't save". Is sbin the right directory? Is ipcfg the right file to edit?
When I reboot my CenOS, my nic does not. If I run eht0, I get the following: ./network-functions: line 78: icfg-eth0: No such file or directory ./network-functions: line 78: No such file or directory Usage: grep [OPTION]... PATTERN [FILE)... Try 'grep --help- for more information
The information in /etc/sysconfig/nework-scripts/ifcfg-eth0 is: #Advanced Micro Devices [AMD] ... Device=eth0 ONBOOT=yes BOOTPROTO=None
NETMASK = 255.255.255.0 IPADDR = **.**.**.** HWADDR=**:**:**:**:**: Gateway=**.**.***.* TYPE=Ethernet How to rectify this?
I have a finely working CentOS server. I want to clone the complete OS (over network) so that I can use it for same functionality on several other machines..
I've been attempting to setup PXE/HTTP network installs so we can better handle deployments for new systems. I have a test CentOS 5.4 VM running, and another test VM that I want to deploy 5.4 to. TFTP, DHCP are all working correctly. Apache 2.2.3 config "seems" OK. When I kick off the VM which I will install to, DHCP discovery and IP allocation works, the TFTP server is found, I am presented with a menu option of OS selection.
I choose #1, for my 5.4 but then it immediately tells me: "Invalid or corrupt kernel image"
/var/log/messages doesnt show anything other than the DHCP OFFER/ACK process and that TFTP client doesn't accept options /var/log/httpd/error_log doesnt show anything either Not sure where else to look for diagnosis. My Apache config directory: /var/www/html/CentOS
My Apache DocumentRoot: /var/www/html/CentOS Directives: <Directory "/var/www/html/CentOS"> AllowOverride None Options None Order allow,deny Allow from all </Directory>
Forgot to add this line from my pxelinux.cfg/default file: label 1 kernel 5.4/vmlinuz append initrd=5.4/initrd.img ramdisk_size=16000 method=http:/10.37.129.3/CentOS ip=dhcp
(I think I have found my problem.. 5.4 was in the TFTPBOOT directory, but now that I'm using HTTP, I changed this to be: kernel CentOS/vmlinuz and append initrd=CentOS/initrd.img) -- question is, will just changing this work?
I am trying to setup a network bridged Server on Centos 5 like belows,
Broadband Router (NAT mode) ---> Bridged server (with t Proxy)--> Client PC .
after installing and configuring bridge, client can browse. But, i want to make this server working as a transparent proxy.But, my bridged proxy is not working. i need to use iptables command to make it properly.
