Is there a way we can create a WAN Balancer on Centos or Fedora?
If yes what are the essentials hardware requirements to achieve the same?
And also let me know if there is any reference URL that I can go through?
I have heard about Untangle as mentioned in the below URL but want to find out if it can be achived on CentOS or fedora.

How to configure load balancer to create a 4 server web farm.
View 1 Replies View RelatedI am using haproxy for the first time.I downloaded the latest version 1.4.7 and then unpacked it.then opened the terminal and wrote the command
After which an executable haproxy file was created which I copied to /usr/local/sbin. then i wrote $sudo make install. then I make a configuration file in /etc/haproxy.cfg which is as follows
But it's not working it is various kind of errors intially it was showing "cannot bind to socket" so tried changing the port number but didn't help. I also used command like $sudo sysctl net.ipv4.ip_nonlocal_bind=1 But didn't help.
I am working on a load balancing project. The type of routing I am implementing is direct routing (LVS-DIR).
The following is a script that sets up the Linux Virtual Server (LVS) or the load balancer:
On both, the LVS and Real Server 1, the firewalls (iptables) are not running.
A few questions I have are:
1) On the LVS, is apache supposed to be running?
2) If so, what would be the ServerName for apache on the LVS?
3) What would be the ServerName for apache on the real server1, is it the server real IP or the VIP?
When I try to access the web content on real server1 in a browser on the LVS, I get Failed to Connect. A connection to the server cannot be established.
The load balancer has two NICS, eth0 and eth1. The real servers will connect to the load balancer via eth1, and the client will connect via eth0.
I have set up one of my linux box as link load balancer for two ADSL connection. After deployment, I have found out that instead of being fast, it has become slow. What I have observed that my request get out to internet but comes back intermittently. Is this a standard scenario ?

My iptable T1:
http traffic not follow the iptables. sometime via eth1 or eth2
After squid.conf added "tcp_outgoing_address wan1's gateway" it worked correctly
Why? what squid do?
The http traffic:
Why iptables can't not control the traffic
I want creat the tables T2 =>for load balancer
How to make squid route follow this table
My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. Do you have any idea what open source solution i can apply for my problem?
I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.

View 3 Replies View RelatedI have just taken on a dedicated server sitting somewhere in Norfolk. I have created a website that uses PHP to connect to another remote server in order to interrogate a MSSQL database. This script, running on Apache, uses a VPN connection to connect to the remote server.To test, I have Apache on my laptop at home and just used Microsoft Network Connection to create the VPN connection.I have now uploaded this site to my new CentOS server and need to create the same VPN connection. I understand this is a command level and have been advised to use OpenVPN which I have successfully installed.My problem is I only have the details remote ip address, username and password. I believe I have to use the 'client.conf' script instead of server.conf.

I have a cgi script that tries to get the IP address of a domain. the Domain is defined in Bind, yet it can not resolve it. I put the domain in the host file and it then gives a Error: unable to create socket - Permission denied
I figure I have to do some code changes to the script but here I would like an explaination as to the error I am getting.
Have been playing with Centos 5 and finally got it installed and have done most of the updates. Before I proceed much further it would be nice if I could create a backup/install disc of how it is now. No Data,just the setup and software used etc.Have a dvd rw on the server.I recall mondo rescue installed years ago on a linux server we used.

View 9 Replies View RelatedI have a CentOS 5.5 server running currently with a Netgear gigabit ethernet card and for wifi I have a wi-fi card with the chipset: RT2860.Now I have gotten the ethernet card and wi-fi card working but my main question is: How do you bridge the connection between the ethernet card and the wi-fi card to create a wireless network with a hidden ESSID if possible and WPA encryption? (So the server basically acts as a wireless router as well as doing all the other stuff I need to do on it).
View 2 Replies View RelatedI'm in the process of creating local repos for our company servers (CentOS 5.5) and laptops (Fedora 13). And while the CentOS part went perfect the Fedora part is causing major trouble.But first things first, here's the setup: a central CentOS 5.5 server is running Apache2 and has a VirtualHost listening on Port 8080 for both CentOS and Fedora. The DocumentRoot for this VirtualHost is /data/repo wherein two directories, centos and fedora, reside.
This is the .repo-file for CentOS that works like a charm:

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.

I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).
