The install went fine but the only issues is getting the server on the network.
I can't ping any thing other that the ip address assigned to the server.
I did it through the gui , the command line and using ifconfig and editing the ifconfi-eth0 file and nothing works.
any ideas on how to get this to work.
i see nothing wrong in the messages.log file either.
i am a fresher to linux. presently i am using CentOS for getting some experience in that. but i have a problem with internet connection using in CentOS. i am using prolink USB ADSL2+ modem (H5200U). so, i request from all readers to give alternative answer.

I am having a problem getting a wireless network connection on my DELL laptop running CentOS 5. I have no problem getting a wireless connection when the laptop is booted in Windows XP. I also don't have a problem when booted under CentOS 5 and there is no authentication setup on the wireless router. I only have a problem when I setup authentication. The router wireless log shows the PC connectinng, authenticating, and succeeding authentication.I am using the Broadcom Hybrid-wl wireless driver.
View 19 Replies View RelatedI 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:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes
TYPE=Ethernet
[Code]...
This is a fun one (x used in place of real IP's and hostnames):
Code:
$ host 134.174.xxx.xx
xx.xx.174.134.in-addr.arpa domain name pointer xxx.xxx.xxx.com.
$ host xxx.xxx.xxx.com
[Code].....
i want to change eth0 ip address from 192.168.7.143 to 192.168.7.140, but it not changed even i follow the steps in this tutorial this is content of file /etc/sysconfig/network-scripts/ifcfg-eth0.

View 5 Replies View RelatedI have a requirement of switch between wireless network with a single wireless device. First it should be switched to adhoc mode and then after sometime switch to infrastructure mode to establish internet connection. Everything works fine except the gateway settings.
I have used:
system("route add default gw x.x.x.x dev wlan0") to set the gateway, where x.x.x.x is gatewayip address.
I have used this whenever switching happens in addition to ifconfig command to set the ip address and netmask. But this is not setting the gateway ip address. How to set gateway IP address?

With virtualbox I do a test session to train myself with centos before I make big mistakes on my production server.I did take a harddiskfile vdi to another computer with virtual box. Now I have the problem that de MAC-address is changed.I can not get the mac adres anymore, becaus those computer is sold. How can i change the trust of the MAC-address in centos? Or must i change de MAC-address? If I may change the MAC-address, i must do that inside centos, end not inside virtualbox, if you understand me?

I am attempting to get this network card running under CentOS 5.2 but have had no luck. Some sites say to use the sk98lin driver, others the skge, which I can't find at all. I have tried multiple versions of the driver in rpm but none seem to work. The card shows under the network manager but will not get an IP address from the DHCP server.
Here are the outputs for this card.

How to get this working as we have 3 of these cards for computers without a Gb NIC and I don't want to fight with it 3 separate times.
New to CentOS5.5 I'm experiencing some trouble in order to continue my configuration. I've just installed my vmware tools and configured my network card with system-config-network
Edit eth0 (eth0) - vmxnet3 -> with a static IP I rebooted my server and since then I lost my eth0. I still see it in system-config-network, but I can't active it anymore.:
/etc/init.d/network start Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring. [FAILED]
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?
ifconfig:

I'm using Ubuntu 9.10 on a Lenovo ThinkPad T61 using an Intel PRO/Wireless 3945ABG. My laptop's ability to connect to a wireless network stopped last night, and I'm not sure why. It's definitely something on my end, as my roommate can connect to the internet on a Windows box. I can wire in without a problem, but that's a pain and my Ethernet cable got lost in the shuffle when I moved back to school. I've been able to get into this network before and nothing about it has changed. I've been able to hibernate and restart and such and nothing has ever needed to be reset.
The router's a D-Link WBR-2310. Wicd and Network Manager see the network (I'm back to using wicd) , but wicd appears to get stuck at "Obtaining IP address..." and says "Unable to connect: Cannot obtain IP address". I know my password is correct (I set up the router and I'm the CS undergrad in the apartment so I manage it), lspci sees the wireless card, ifconfig and iwconfig return information about the interface, dmesg|grep wlan0 doesn't seem to have anything terribly out of the ordinary, but here's that output:
Code:

I've tried:
- reinstalling wicd
- uninstalling wicd and installing network-manager
- restarting
- shutting down and booting back up
- restarting the router
- sudo /etc/init.d/networking restart
- taking the interface down and back up with ifconfig
I haven't changed anything recently in regards to my wireless card, and all the fixes I've tried are things I've done before without an issue. The only thing I'm wondering about is if doing a hard reset might have broken something (I know this is a cardinal sin, but there's a whole 'nother problem I haven't been able to fix with the OS hanging every once in a while over a VPN daemon when it tries to shut down or restart -- I've left it for hours to see if it actually gets anywhere and no luck, won't do a soft reset). I'm nervous about reinstalling the driver just because I've never had to do it and drivers are a finicky business. I imagine there's a config error somewhere?
I run an centos server. From the console I can ping google.com and get a reply. But when I ping another address say xyz.com, the IP address is resolved (11.22.33.44) but there is no reply. In the same network in our office from my desktop I ping [URL] and there is a reply.I turned of the firewall but still the same problem.
