Ok.. I guess to better ask my question... how to assign server public static IP centos? Like for example I am in the router itself.. where would I go to point ip 44.33.33.21. to ?> 192.168.1.4
What would be the most common in the routers?
I am running a modem in bridge mode to my server
I edit file /etc/sysconfig/network-scripts/ifcfg-eth0 code...
I do service network restart and get nothing ? No connection... Are there other files I need to edit?
Server has been moved to a different locations and so the IP has been changed now the hostname is changed to something other that what it was before.
Could it be the rDNS that is causing this?
Note: this is not a DHCP connection.
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:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes
TYPE=Ethernet
[Code]...
how do I change my 192.168.1.3 to a static ip?
I went into nano /etc/sysconfig/network-script/ifcfg-eth0
I add in IPADDR=192.168.3.55
I do service network restart and it doesn't change to the correct.... ip ??
I'm replacing a USB adapter with a PCI DLink card that is an Atheros chipset. I installed 'madwifi' for the modules and can set the ESSID and WEP key manually using iwconfig and can get a DHCP Address using dhclient.
What I want to do now is bind this to the static IP that the USB device used to have, but I am not sure how to do this since Atheros chipsets show up as both wifi0 and ath0, with ath0 being the one that needs to have the connection info. I tried setting up a ifcfg-ath0 with the static IP information and the key-ath0 file with the key like I have for the USB device (which shows up as wlan0) but at booth ath0 isn't up and running, even with ONBOOT=yes. What do I need to do to get an Atheros chipset to boot with a static IP?
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).

How would I configure the wireless card statically, e. g. by editing /etc/sysconfig/network-scripts/ifcfg-wlan0?
This would be something like :
DEVICE=wlan0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.1.252
NETMASK=255.255.255.0
ESSID=my_essid

But I don't know how to define the WEP key here.
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 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.
I am using centOS 5.0. After I change from DHCP to static IP address, I cannot ping hosts on the same subnet. The error message says destination host unreachable. Before I made the changes I was able to ping and now even I change it back to DHCP I still cannot ping with the same destination host unreachable message. The centOS is running on VMware on a Windows host.
ifconfig shows
eth0 Link encap:Ethernet HWaddr 00:0C29:A1:9A:10
inet addr: 192.168.0.202 Bcast:192.168.0.255 Mask: 255.255.255.0
inet6 addr ......
After pinging 192.168.0.106 (106 is on and other host can ping it), arp -a shows ? (192.168.0.106) at <incomplete> on eth0 I tried different ways by disabling the firewall and and disabling SE protection. No Luck.
I am having a problem with when I bind a static IP to my NIC I loose all network connectivity but, if i leave it set to dhcp it works fine. I've gone over all my settings a thousand times and they are all correct. Has anyone else had this problem or give me a hint as to what the problem might be?

I eventually get prompted for network config, where I choose manual configuration.

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 had made following entries in my httpd.conf file at centos5.5.

When i am trying to access the any directory other on port *80, its not being accessible from the static ip which is routed through a DMZ server. http://122.165.35.9:8085 something like this returns the error "could not connect to web browser"

Is it essential that I request a static IP from my isp? or could I suggest to the webhost that they whitelist the first portion of my IP which rarely changes? i.e 90.195.xx.xx, or *sky.com for my ftp account?

I have 2 Ethernet connections, one (eth0) for the internet which gets set with dhcp, and one (eth1) for my internal network on which I have dhcp3-server running. I set eth1 to use static IP in interfaces, but every time I reset the network, it is fine for a couple of minutes, and switches over do being served by my own dhcp server on the same machine. (the interfaces file clearly says "iface eth1 inet static")

You'll notice the IPs are a little strange. This is because the sever is now on a special subnet dedicated to isolating specific servers. I also edited the resolv.conf file to include the proper DNS servers (including one of Google's just in case all hell broke lose).The problem is that, seemingly randomly, the machine will lose the ability to talk to the outside world. I know the machine is still up, but it acts like it has no networking at all.
I think part of the issue is that there is no DHCP running to this subnet (nor will there be) and the dhclient seems to still be running on occasion which causes some sort of conflict (no idea what) which causes networking to die. I cannot, however, remove the dhcp3-client package as it also causes the ubuntu-minimal package to be removed and that would be bad.
