Feb 12, 2009I have two CentOS servers on the same LAN. One is CentOS 4.7 the other 5.2 They both also have a WAN interface to the same remote network. On CentOS 4.7 I can ping the remote network through the CentOS 5.2 server. i.e. ping -I eth0 remotehost On CentOS 5.2 I can NOT force the ping to go out the CentOS 4.7 server without over riding my routing tables to make eth0 a more direct route than the eth1 route.
On 5.2 If I do the ping -I eth0 remotehost, and a tcpdump on eth0, the outbound ping will not be going out eth0, he overrides it and sends it out eth1. In fact, on CentOS 4.7 if I do not have a route to the remote network through the other server (turn proxy arp off on the 5.2 machine), I will get "Destination Host Unreachable". I would ideally like to get the 5.2 machine to behave the way the 4.7 machine does.
My real life application for this is that I have a CentOS server in a location that controls access to the Internet. There is another router on the netowrk that handles traffic back to our corporate office. the CentOS server also has the ability to get to the corporate office. I ping the corporate office through eth0 to find out if the link through the other router is indeed up and active. I want to make this a CentOS 5.2 server but alas, I can not tell if the other route is up or not.

Oct 2, 2009just finished installing Centos5 and I had no problems installing it. But when I tried to connect to the internet, the trouble began.My network card is installed and the status is "OK". The network card is a "Realtek RTL 8168C(P)/8111C(P)".The status of the device said "Inactive" and when I tried to activate it, it came with an error: Failed; no link present. Check Cable?Now the cable is connected as it should be.So next step I did is put in a static IP. Now the activation works fine.However I still have no internet. I can't even ping to my router!I need some new drivers for my graphics card too, but first I need the network to work, than I can download other stuff..
View 6 Replies View RelatedNetworking :: CentOS 5 - Cannot Ping Win7 Addresses
Feb 10, 2010I have a box at home that I've installed CentOS 5 on to. I'm new to Linux, so before connecting it up to the router I wanted to try and understand the network settings, so I connected it directly to my other PC with an RJ45 cable. From Windows 7 I can ping all known static IP addresses, but from Linux I can only ping the Linux addresses, not the Windows 7 one. Below are the TCP/IP IPv4 settings, all IPv6 settings are set to auto-assign.
Windows box (uses wireless connection for the router):
Local Ethernet Adapter
IP Address: 30.10.0.1
Subnet: 255.255.0.0
No gateway, primary/secondary DNS.
Linux box:
Three adapters:
Two onboard LAN, both configured to:
IP Address: 30.10.0.2 / 30.10.0.3
Subnet: 255.255.0.0
Gateway: 30.10.0.1
No primary/secondary DNS.
One LinkSys PCI card:
IP Address: 20.10.0.1
Subnet: 255.255.255.0
Gateway: 192.168.1.1 (my router)
Primary/Secondary DNS: my ISPs details.
The idea was to connect the box directly to the router (with RJ45) and to be able to remote login from my main PC to this one. This box is to be my home server, which I was going to put virtual machines on to for things like my development work and such.
Networking :: Unable To Ping Between Centos And Windows XP
Dec 16, 2010In my office i have a network of 172.16.31.0 and a squid proxy server running, all other systems have windows XP and one system has centos. On centos system i have three lan cards and i want to test some things on it. So i assigned another IP on it of range 192.168.7.0/24 and same range on another windows system. And all the systems connected through a same network switch.
Unable to ping between Centos and Windows system. If i ping from one centos to windows system with the series of 172.16.31.0 then it replies very well but same thing is not happening in other 192.168.7.0/24 IP series.

CentOS 5 Networking :: Can't Ping Or Otherwise Access Internet
Mar 14, 2009I just downloaded and installed the latest Cent OS 5. I disabled SE linux, turned off the firewall, and selected the Server package options when installing. I plan on using this as a router/firewall between my internal network and the internet, as well as web server, etc. The first thing I did was to configure the two NICs, internal one with 192.168.7.1 address and the other with an address from my ISP (I have a static address, but I also tried to let the DSL router assign an address via DHCP). Everything looked fine, I checked /etc/resolv.conf and my routes. I was able to ping the DSL router from the server, but I was not able to do a ping or lookup on anything outside my network. I tried host, dig, nslookup, etc, no luck. Obviously then, I was not able to browse the net with firefox.

Mar 10, 2009Running Fedora 10, I installed CentOS 5 in Virtualbox, but I can't ping the Virtual Machine...
From within CentOS, I can ping my laptop [known as the host?] but from the laptop I can't ping the CentOS Virtual Machine. I tried turning off the firewall on both too... CentOS was able to access the internet through my laptop right away without any configurations too.
Unless someone has an idea to resolve the above, I am also wondering about something else VirtualBox-related:
To see if it was possible to get around the above issue, I was going to install another CentOS virtual machine to see if I can get them to communicate both ways [if at all], but to do so, I think I have to install CentOS AGAIN on another allocated amount of hard disk space. This will take some time, so I was wondering if anyone knew if it was possible to just create a quick duplicate of the previous installation, if you wanted 2 different virtual installations of the same OS.
Networking :: Centos Cannot Ping Hosts On The Same Subnet After Change To Static Ip
Jul 26, 2011I 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

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.

Feb 15, 2010I have OpenVPN running successfully on a CentOS Linux server. All remote clients connect without a problem and can ping the server LAN (10.5.0.0/24) . The server address is
10.5.0.1. All network shares on the server are available to the remote clients via SAMBA shares and this works well.The problem is that I am unable to get the remote clients to access services on the LAN clients. For example, there is a webserver running on a Windows XP PC (on the server LAN @ 10.5.0.2) with no firewall enabled. The remote VPN clients can ping this webserver at 10.5.0.2, but cannot browse the webserver at [URL]. All clients on the server LAN can however browse the webserver. The remote clients are using Windows XP and VISTA with OpenVPN 2.1.1.
I am new to VPNs and networking, but from my research, it seems as if this may be a routing issue. I would appreciate any help you may give in getting the remote clients to access the services on the LAN clients (other than the server @ 10.5.0.1).
The server configuration is:

Apr 20, 2011I have a dedicated host on my lan to monitor other hosts/services using Nagios. I'm in the process of migrating to Zabbix on that host to perform the same purpose. Both Nagios and Zabbix monitor icmp ping latency (Nagios uses ping, Zabbix uses fping) and over time the latency to other hosts grows until threshold alarms are triggered. In one week, the average latency grows from sub-millisecond to over 100 milliseconds, and continues to grow until the Nagios host is rebooted. I have verified the latency numbers using ping/fping from the command line on the Nagios host.
The problem is that pings from the monitored hosts to the Nagios host show normal latency at the time the Nagios host is showing high latency from itself to the monitored hosts. The Nagios host and monitored hosts are all connected to the same Dell 24 port gigabit switch. I already posted this question on the Zabbix forums with a graph of the latency but there were no answers. [URL] why the icmp ping latency is growing over time and how I can fix it short of rebooting the host on a schedule.
