I am trying to install a router on my CentOS 5 box, while i have properly configured IP address, Subnet, Default GW and DNS, I am at the point of trying to set up the Proxy. I have added a line: "proxy=http:ip_address:8080/" to the file of "/etc/yum.conf" The Proxy server here does not require any username nor password however I still cannot ping any website, while I tried to ping 126.96.36.199 (google.com) it returns the following message:
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 (188.8.131.52) 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.
I installed the Centos 5.5 and after the Xen. After I put a virtual machine named VM01.Initially it worked properly, I tried everything and it worked.When rebooted, I had problems with the network.I have two network cards eth0 and eth1, but eth1 does not have any ip and I use only eth0.The error that appears is:
vif0.0: received packet with own address the source address
somebody please tell me whether it would be all right to install xp inside CentOS using VMware or it's better to do vice versa if it is ok to install xp inside centos then at the beginning when i install centos should i allocate all hard disk to this OS and later give some to xp , or initially i should keep some space for xp and install centos in the rest ?
I have set up a MythBox on Debian Lenny. I have a wireless connection using a Belkin USB WiFi Device. I am using ndiswrapper, wpa_supplicant, etc. I am using a static ip address. I have internet access without problems. However, if I try to ssh in or even ping my mythbox inside my network there is no connection. I have never had to do anything special to ssh into debian in my network before. I am confused that I have an internet connection but can't get a ping reply.
I am using centos box as a router. WAN side has a public ip and lan side also using a public ip. I configured dhcp server on the LAN side and it is working perfectly, pcs on the LAN side can able to access the internet.
Problem: Considering the fact that LAN IPs is using Public IP and it is presumed that from the internet it can be able to ping IPs inside the LAN but, alas, it couldn't.
No firewall has been config!
Question: What config should be done on the box so that IPs inside the LAN can be ping from the internet?
I have configured (bind) my server with multiple static IP. I can ping the main IP from outside but not the other IP . I can ping all the IP from localhost but not from the internet. I do not have any external firewall or blocking device. server is directly connected via modem. If anyone could advice me for why i cannot ping other Ip's
I have installed Centos 5 on a virtual machine (esx4i). I set it to obtain an IP address from the DHCP sever, which is a broadband router, it has been given an IP address of 10.10.11.159 the router is 10.10.11.1 but I can't ping the router and I can't get any access to the network! I have a SCO Openserver server on the same physical box and it works fine so I know the network card & cable is ok.
I posted it on another forum, but could not get response,So I have this cenOS, Ubuntu and windows operating system running on virtual machines.Now I gave them manual ip address, both ubuntu and windows machines can ping the default gateway, but not the CentOS.It should forward 0.0.0.0. to my cisco router address(192.168.5.254),
I have 4 centos5 apache webservers all on the same network, recently, 2 of the webservers have stopped being able to ping or browse one particular website where feeds are obtained from this site. I have checked and firewall and selinux settings are disabled. The two webservers are able to ping and browse other sites. Dns settings are the same for all 4 servers. traceroute for working and not working webservers are the same.
I've been struggling with this for a couple of days now. I'm trying to setup a reverse proxy with SSL. The config works when it's not using SSL, but as soon as I setup the virtualhost for 443, I get a ERR_CONNECTION_REFUSED in my browser.
The setup is that it's a CentOS 5.6 running Apache 2.2.3. I was configuring it via this guide: [URL]
This server is acting as a reverse proxy for a Windows server running Apache. Currently, I'm just trying to get the manager page from the Windows server to go through the reverse proxy. Here's the virtual host section of my httpd.conf file on the reverse proxy:
<VirtualHost *:443> ServerName aspwebview.vtinfo.com SSLEngine On SSLCertificateFile /etc/httpd/ssl/star_vtinfo.com.crt
Thoughts? Is there anything I have to do on the Windows server (maybe in the connector section of server.xml)?
I am accessing internet through Analog Proxy. ADSL modem has been connect to one of windows xp machine and by running Analog proxy, we uses internet by mentioning that machine's ip address. But how do i ping the default gateway in this case? Is it possible or not? If yes then please tell me how, because if i says # ping <anysite.com> it not pinging; its says host unreachable; means i will not be able to run wget too.
I am trying to ping from OEL 5.3. In one of google link; i read that :Does PING work through the Proxy Server? No, ping uses the ICMP protocol to communicate. Proxy only supports TCP and UDP packets. Ping will resolve the DNS name but go no further.
I 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).

I am attempting to use yum behind a MS Proxy. I am receiving the following error:

My past few weeks trying to cache the use frox, but never managed to run frox correctly. I need a guide for installation frox (ftp proxy or otherwise) that I can understand, because I'm still just learning. I use a superbly managed using squid for web proxy using port 3128
What is the fastest setup to do this? All I want is an internally authenticated webmail server that other servers can send mail to for collection of test emails. Don't need LDAP or anything fancy, just a internal LAN only webmail server. I've got Squirrelmail setup on Ubuntu Server and can't get authentication setup with Squirrelmail and every tutorial I read is way over complicated or has nothing on how to authenticate Squirrelmail with internal, system users.
One of our client having issue with the qmail. The issue is if any one send email to email@example.com (firstname.lastname@example.org the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.
I've set a two-node cluster using Pacemaker/OpenAIS. I have only one network and if I break this one, the communication between node is interrupted ... With a ClusterIP resource, when network is breaked, then each node start the ClusterIP => 2 same IP .. Is there a way to define the prefered location of a resource when connection between these nodes is broken ?
A <==> B
If one of the node lose the network, then follow a previously written rule : start resource on A (for example). B will know than it's not the prefered node and so, will stop to serve. Possible ? This is because if both node are connected, but a problem between these node occur and client can join both node ... then the split brain is problematic ... A better solution is to add a rule when the split-brain occurs : all node wich can't reach the gateway have to stop all resources ... And so, if it's A wich lose the network, service will start on B and only B without any problem ...
