This card was working perfectly fine up until....an hour ago and it started doing this. My iptables isn't blocking it somehow, because I didn't change anything. I tried reverting to an older kernel and that didn't help. It's not the network cable, it works fine in any other card. Also, the dropped packets seem to count down? It seems to go down by exactly one every time I run ifconfig, no matter the length of time in between running it.
I recently installed a new CPU and motherboard in my Media Server, but the ethernet port isn't showing up under ifconfig. Is there any way to install additional drivers? EDIT: The model is Realtek RTL8111/8160B.

PC1 and PC2 are linux pc's with linux 2.4 (or) 2.6 kernel installed on it.Observations are done on both 2.4 kernel and 2.6 kernel Problem explination:
1)PC1 "ifconfig eth1 down" on linux shell.
2)Check the "ifconfig eth1" on PC2
3) The running flags are unset first(disappear)and set(Re-appear) on the eth1 interface on PC2.
4) unset and set toggling happens with in short period of time about 1 or 2 secs.
This is clearly observed in linux 2.4 kernel with some time delay for the toggling, but 2.6 kernel this will happen every quickly..

I did a yum update this morning that included a dnsmasq update. Subsequently, for an unrelated reason, I restarted dnsmasq, but it failed because /etc/dnsmasq.d didn't exist. It looks like my /etc/dnsmasq.conf file now includes "conf-dir=/etc/dnsmasq.d" at the end. Since dnsmasq was starting and I didn't remove dnsmasq.d, I assume this line was added by the update. Commenting the line resolves the issue.
An alternative hypothesis, given that I don't really know what the state of /etc/dnsmasq.conf and /etc/dnsmasq.d/ was before the update, might be that the directory did exist, but was removed by the update. I find this the least likely of my 2 stated hypotheses. (There are other hypotheses, but I think they are even less likely). Am I correct is concluding the conf-dir line was added by the update? If so, shouldn't the updated RPM create the directory during install?
I trying to set up a LDAP server using openLDAP / db4. The server runs fine but I cannot get the client to work. Client and server are on the same machine, as for now. The problem seems to be in PAM. However I cannot start the system-config-authentication tool which should do the trick.

I've been racking my brains over the past few days trying to figure out why my NIC card (network interface card) won't show up in the ifcfg-eth0 file.When I configure a new server (like this one) I always go to:/etc/sysconfig/network-scripts/ifcfg-eth0 and from there I usally see the name of my NIC's manufacturer's name and the hardware MAC address.Then it's only a simple process of entering the server's IP address, netmask and gateway and I'm up and running in no time...But not in this case! the ifcfg-eth0 file is completely blank! There's not ONE single line of config info in it... (?)The server runs an Intel core 2 duo (dual-core) CPU with 1 gig of RAM.
I've even re-formatted the drive and re-installed Centos 5.1 on the darn thing 3 times and it simply won't work.The server cannot resolve when I do a wgetIt also gives me a 'resolution problem in the named configuration'.What I don't understand is that the 2 small LEDs on the Cat 5 cable lights up and flash at what appear to be regular intervals here.
Just installed a new CentOS with the control panel Interworx. Everything fine, BUT. I can't add new ipadresses cause there is no network device.When i do 'ifconfig' i get the following:

I'm trying to seup my dual ethernet card. One to go to the internet and the other to serve the LAN. Do I need a router for the NIC that will serving the LAN and another one to the NIC that will be connected to the internet? I don't want the LAN computers to connect to the internet. Can someone please give me a description on how to set this connection. And yes I will be using my server as a DHCP and DNS BIND.
View 5 Replies View RelatedI am configuring a new installation of CentOS 5.4 with the goal of setting up a server. Ive been through the installation and set up everything that I thought that I had to setup. Im getting into CentOS because my work utilizes this distribution. I do have some debian experience, and I have used Ubuntu on both server and desktop platforms.
Now, when setting up Ubuntu, I found that I was able to get networking up much easier. During the initial installation it had asked me to choose between DHCP or manual configuration. As this is going to be a server I want it setup with a static IP. But for some reason no matter what I do I can not get the machine connected. I go so far as trying to do a 'yum update' and I can not make a connection.
A few things Ive noticed that might be applicable here . . . . .
For DNS servers, I am unsure exactly what I need to put here. My ISP is Cox. I am not sure what NS's to put there for them, so I thought that I would be able to use third party DNS servers such as OpenDNS or the Google Public DNS. I know that I have setup my debian server like that with no issues. Also when setting up my debian server it prepopulated certain areas that I am required to fill when setting up CentOS. Example, when setting up localhost.localdomain -- I would choose my hostname and local domain was prepopulated as ph.cox.net. I dont know if this is something that I have to use, or if it would change if I am using third party DNS.
My resolv.conf file looks like this
search ph.cox.net
nameserver (IP address of third party dns either opendns or google)
nameserver (IP address of third party dns either opendns or google)
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
Centos-2
IP: 10.0.2.16
Gateway: 10.0.2.2
DNS: 10.0.2.3
Centos-3
IP: 10.0.2.17
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.
I'm setting up a LDAP server to centralize the admin of a bunch of Centos 5.2 servers. I've got the LDAP server set up. I've got my client machines reading their autofs mount tables from LDAP. Now, I'd like to get name resolution working via LDAP.
Here's what I have so far:
1) /etc/nsswitch.conf contains the line "hosts: files dns ldap"
2) /etc/openldap/ldap.conf has URI and NSS_BASE_HOSTS set up to indicate root of "hosts" subtree in LDAP database.
3) "hosts" node in database is an "orginizationalUnit" object.
4) Below "hosts" I have a number of "ipHost" nodes defined with "cn" set to host name and "ipHostNumber" set to host's IP address
This setup doesn't work. Attempting to ping a host by name locks up. If I take the "ldap" keyword off of the "hosts:" entry in the nsswitch.conf file, the ping then returns immediately with "unknown host".
I'm surprised that there isn't better information available online on how to do this. I've found bits and pieces, but nothing concise. how to get name resolution working through LDAP?

I have a Sprint U760 air card that apparently works under Linux. Sprint has a guide: "Wireless Mobile Broadband Setup Guide for Linux OS" that I am using to setup the air card. When I go through the procedure in the manual for "Setting Up PPP Using KPPP" the last task is to query the modem to see if Linux recognizes it. When I do the query I get a response "unable to open modem". I have tried going back through the PPP setup but still get the same response.
