View 6 Replies View RelatedI am fairly new on CentOS and am in the process of setting up a small home office network that shares Internet access through the Linux (CentOS) box.I have two network interface cards The Linux box is also the DHCP server. My challenge is to get the client machines to access the Internet! I have a PPP connection to the ISP. Essentially I followed these Instructions CENTOS REDHAT Internet Connection Sharing. Pretty straight forward but I am still not able to get clients to access the Internet. I defined the DNS server through DHCP (196.44.x.y). I assumed it has to do with default gateway and it is set as follows: on the Linx box the gateway is my ppp0 link. DHCP uses eth1 (LAN card) fixed IP as the gateway. All clients are reflecting this information. The firewall (iptables) is reflecting the FORWARDING and POSTROUTING rules as advised.
Is there a step I mioght have missed to get this working? I tried to Google but its not getting me far.

I installed CentOS 5.6 (kernel: 2.6.18-238.12.1.el5) with X Window on my HP Compaq 6710b. I also downloaded the firmware iwl3945 for my Intel Pro Wireless 3945 and manually installed it, reloaded the iwl3945 module and enabled NetworkManager. I could then get the wireless network connection worked on my graphical environment. I installed additional software manually by using the terminal window (Applications --> Accessories --> Terminal) and everything worked perfectly.
However, when I switched to text-based environment by issuing the commend "sudo init 3" (changing the user level) and logging in as root, I could not get any internet connection. I tried to use lynx and I got the error message: "Unable to connect to remote host". I am a complete newbie in Linux and I tried to google and search for solution within centos.org but I could not find.
I am setting up a Beowulf Cluster using CentOS 5.5. I have the head node with two NIC devices eth0 and eth1. eth0 is the one that is connected to the WAN while eth1 provides the internal LAN connection. I am trying to configure internet connection sharing with the slave nodes on the network so that I can update/install software as needed via ssh sessions using yum. I have set up the master node with the requisite changes to iptables to enable IPv4 forwarding. From my slave nodes I can ping ip address from the terminal, but my domain name resolution is not working. i.e. if I ping [URL] it can not resolve, but if I ping 74.125.224.50 (one of google's IP's) I can communicate with the machine without a problem. I also ran the configuration tool provided in the README section of the forum on the slave node and the master node. The links are:

Just checking to be sure. 5.3>5.4 update went without a hitch:) But a message ran about (/etc/yum.repo.d) CentOS-Base.repo.rpmnew. Comparing CentOS-Base.repo with the new one show the 1st has the correct priorities and .rpmnew does not have the correct priorities. Should I remove the *.rpmnew repo after making sure it otherwise is the same as the original CentOS-Base.repo?
View 1 Replies View RelatedI am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.
View 2 Replies View RelatedI have an MSI K9A2 Platinum mobo, which has a 10/100/1000 Fast Ethernet Realtek 8111B built-in, a D-Link DIR-655 Router and a DSL modem. Compared to Windows Visya and other Linux distros ( Fedora 11, Suse 11.1, Mandriva 2009.1 ) access to the internet is much slower. It seems there is a noticeable delay when running CentOS 5.3. before internet access kicks in each time I am surfing the web or updating my system.
Is there any way I can speed things up, or determine why CentOS 5.3 seems much slower ?
I installed CentOS on Vmware server 2.0.2
I took a snapshot of my machine with internet working
If I reboot my machine I lose internet. This makes no sense to me.
I ifconfig eth0 down then ifconfig eth0 up and still no internet
Weird thing
I check ifconfig and my bcast ID is 192.168.2.255 when it is supposed to be 192.168.45.255
(When the internet is working if I check ifconfig the bcast ID is 192.168.2.255)
IF I change my bcast my internet stops working
If I reboot my machine my internet stops working
I checked /etc/sysconfig/network-scripts/ifcfg-eth0 and I see that in my snapshot (where the internet is actually working) the bcast is at 192.168.2.255
Without rebooting if I edit that script and I put it to .45.255 my internet stops working
If I reboot my machine at any time my internet stops working
I have also just realized that I cannot ping my gateway..
After some testing for a couple of days, I decided to take the plunge and update all my 5.3 machines. Using the recipe from the release notes:
yum clean all
yum update glibc*
yum update yum* rpm* python*
yum clean all
yum update
shutdown -r now
I updated some guinea pigs that I had physical access to and didn't have any issues. So I remotely updated a small farm of LAMP machines that handle a couple of million page views per day. It took each machine approximately 5-6 minutes to download/install/reboot.
I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
