Feb 25, 2011
i have a root-server and a vserver.the vserver should provide services if the root-server is not reachable. i would like to configure heartbeat. its runnung on the root, but on the vserver i get an error: if i set the following in the ha.cf:

5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?

I try to install libapache2-mod-php5 on a vserver for our developer. But it does not work :
yum install mod-php5-apache2
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* addons: mirror.newnanutilities.org

Is the name of the package changed or any other way to install it?

I have setup a MySQL High Availability Cluster with two nodes using DRBD & Heartbeat. I have successfully installed the cluster but one question which is still not solved is that Heartbeat monitors failover of network or server failure, etc.
What will happen if MySQL service gets stopped or do not start. This heartbeat-DRBD cluster does not take any action on that part. Now I want to enable this feature too which also monitors MySQL service. I have gone through MON help on web but could not find out any good step by step tutorial.

I have configured heartbeat+DRBD on a SLES10 SP3 cluster and that's working fine except when both nodes are down and I turn on only one node. When this happens, the heartbeat don't starts automatically (the service status says it's unused, so the services, IP address and partition don't start automatically too).
I can turn on the heartbeat manually (service heartbeat start) and get the services, ip address and partition initialized too, but I'd like to make it starts automatically because it's possible to have one node broken and the person that will turn on the other node can forget to manually starts the service.
-When the heartbeat is unused on the first node and I turn on the second node, the heartbeat on the first node starts automatically and everything is fine.
-The command "chkconfig heartbeat on" was executed.

I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

I got two IP's in my dedicated server. Both are external IP's. I would like to make connections using 2nd IP address under eth0:0 interface. For example: when using "lynx whatismyip.com" should display my 2nd IP. How to do this using iptables ?

I'd like high-availability feature to firewall (iptables) and openvpn service I'm running at my job. Mi project is two firewall boxes in a active/pasive configuration. And if it's possible sync connections' states. I started reading on heartbeat and I'd like to hear some advices and take away some doubts: For the config I'm planning heartbeat service is enough or it would require a CRM service such as pacemaker.

I am trying to setup a High-Availability HTTP Load Balancer With HAProxy & Heartbeat using the below links.
I have all RHEL 5.4 servers hosted on VMWare.
[url]
[url]
This is the scenario, as given in the links as wells as my setup.
Load Balancer 1
Load Balancer 2
Web Server 1
Web Server 2
I have followed all the steps mentioned in the links religiously except the 2.2 here, in which it is asking to configure the vhosts. I could not really understand , what is to be placed in /etc/httpd/conf.d/vhosts.conf file and in which Web Server.
Due to this step only, I think I am failing in Failover test given in Point 4.1 here. I am able to open the webpage by [url] which gives the content of Web Server 1 (http1.example.com). But, when I try to shutdown the http service (to check failover), it does not shows the contents of Web Server 2 (http2.example.com)
Although, I am able to succeed in Failover Test 4.2, in which shared IP 192.168.0.120 switches when I try to start/stop the any of the Load Balancers.

Have someone used Linux heartbeat to send email when the Slave server becomes the Master? I've read I can configure the MailTo under.
But I really don't know how to do it. I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node.

I try to generate a server client code. What i try to do is sending video streams from eth0 and eth1 to the other server programs' eth0 and eth1. In order to do that, i decided to use SO_BINDTODEVICE. But the code is not working. Am i misunderstood the usage of SO_BINDTODEVICE.
1-Defining two ports
2-Defining two sockets
3-Assigning host ips on them

I have a for me very hard to handle problem as I'm quite new to Linux.I want to install openSUSE 11.3 on a virtual Server with nothing more than a ssh shell and root Rights.
Currently running is version 10.3 of OpenSUSE. I tried updating via dist upgrade but at some point it stops with following Error: We do not have enough disk space in /etc or /dev/zerodoes not exist. Exit. error: %post(pam-modules-11.1-5.1.x86_64) scriptlet failed, exit status 1
I know that this is the Result of low RAM and/or swap Memory but in a virtual Server I can't influence those.
PS: The Reason Version 10.3 is in use, are the available preinstalled OSs so there is no higher Version available.

I'm working in windows, and that's why I have been able to access the network. In F14, I was able to access the router address while the internet access ain't. Tried restarting network, and still the problem persists. Tried [URL] and the only thing that i've infered is that IPv4 Failed: FATAL plus, the routing table showed 0.0.0.0 as one of the entries (Gateway). So, i've deleted the wired network configuration from the Network Configuration and checked whether the os would pick it up automatically. It still didn't work.

I have a troubling networking situation that is compounded by the system being remote without any out-of-band mgmt in place nor a serial connection - but am relying on a coworker entering commands into the terminal for me, or doing stuff in the GUI I have an FC12 i386 install running, that was up and stable for 6 days. Primarily this was only being used for a deployment of nTop. Up through Monday evening, I was connecting to the system (in NY) via VNC (here in SF), and was successfully watching nTop do its thing.
Tuesday morning, I go to connect to SSH and I can't get in. The NAT translation is still in place on the firewall, but there is no connection to the NIC/eth0 from the router. This is what I've had my coworker run:
[code]...
I was going to try and have her run the /sbin/mii-tool eth0 tomorrow a.m. just to verify that the interface isn't physically bad? But this is a brand new desktop, and I can't for the life of me understand why this interface went down. I also have the internal IP on a DHCP reservation, which is the same IP listed in IPADDR in the ifcfg-eth0 file - could this be a problem? should I remove the DHCP reservation? I did this so I could SSH to a public IP which I have NAT'd back to the internal 10.0.x.x address I had my coworker take a look at the GUI, and the eth0 properties are "inactive" and the "Activate|Deactivate" buttons are greyed out.I suppose I can have my coworker grab the /var/log/messages and copy to a USB drive, then email me that from another workstation.

I'm trying to write an iptables config file, but got stuck.So I want to define an IP range that allows full access eth0-eth1 forwarding, and another that is allowed to access some special ip-s. The first part works, I could make the range has full access:
iptables -A FORWARD -m iprange --src-range 192.168.80.20-192.168.80.40 -j ACCEPT
iptables -A FORWARD -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -o eth1 -i eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
But cant find out, how tom make the second rule. How could I put speicified target ip-s in this? I've tried to make a new chain:

I am using FC 2, and I get 'eth0 failed' during startup.
I am configured for DHCP
device is 'inactive' under network device control after reboot
click 'activate', sometimes I can surf, others not.
When I can't get online, sometimes deactivating and reactivating works.
edited connection to 'activate device when computer starts'
eth0 still fails at start-up, and device is inactive.
I am supposed to use FC2 for my schoolwork

I have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.

I'm currently trying to configure Linux heartbeat on my two Linux servers(where SMPP service is running) my two machines are in two different location with different notworks (primary is in 192.168.x.x and secondary is in 10.48.x.x network)
I want to know whether is it possible to configure heartbeat between two such different networks (what i found by surfing internet is the way of configuring in same network) if possible, can i configure to listen to my primary server IP instead of having a secondary IP in primary server (since my SMPP service is running with my primary server's IP)

I am currently trying to setup a cluster using heartbeat. Unfortunatly it does not do what I want to do. I am using heartbeat 2.1.4-11 on a readhat system. I am using the the cib for configuration. What I want to do is the following: I have two Nodes. I want to run a clone resource on both nodes. It's named I want to run as a clone. This works fine.Additionally I want to have two virtual IP adresses. One should be set on Node 1 the other on Node 2. This works fine as well. I want to set dependencies between the resources. And this is where I have problems. What I want to achive: In case named is not able to run on a node, the vIP should switch to the other node (which then will have both vIPs). In case both nodes are able to run named, there should be one vIP on each node. Sounds simple, but does not work.Accourding to the heartbeat docu this an be achieved by using

If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got
Quote:
Ignoring unknown interface eth0=eth0.
ifconfig tells me
Quote:
eth0 Link encap:Ethernet HWaddr 00:25:64:e8:18:2c
inet addr:192.168.0.112 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::225:64ff:fee8:182c/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[code]....
so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
