How To: Load Balancing & Failover With Dual/ Multi WAN on Linux proxy server I have 3 WANs connection (2 ADSL and 1 Wimax). And 30 clients on LAN.
eth0 connect with Wimax
ip= 172.23.x.x
eth1 connect with ADSL1
ip=10.10.6.x
eth2 connect with ADSL2
ip= 10.10.5.x
eth3 connect with LAN
ip=192.168.1.x
how to do Load Balancing & Failover With Dual/ Multi WAN on Linux proxy server.
My netowrk interface:
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
I have OpenSuse 11.1 installed in a system as server (without graphics). We have 3 NICs, 2 of them connected to 2 different ISPs through gateways, as follows:
IPs for NICs: IP1=192.168.5.2/24; IP2=192.168.6.2/24 dev=eth2
Gateways: GW1=192.168.5.10; GW2=192.168.6.10 dev=eth3
Third NIC connected into the internal network with and IP=192.168.11.2/24 dev=eth0
We added ip routes and rules as follows (used tables created with vim in the rt_table file with numbers 20 & 30):
ip route add NET1 dev DEV1 src IP1 table TB1
ip route add default via GW1 table TB1
ip route add NET2 dev DEV2 src IP2 table TB2
[code]....
ip route add default scope global nexthop via GW1 dev DEV1 weight WG1 nexthop via GW2 dev DEV2 weight WG2 from the server I could ping Yahoo! and ping any PC connected in the internal network (192.168.11.xxx). Fro PCs I could ping all the IPs of the server but not the GWs neither any web site, I couldn't surf either.

This is my first time to test piranha and I can't understand couple things:
1. how to setup public floating IP address between active and backup piranha node?
2. does piranha nodes have to run on public IP?
3. how to connect active piranha node with backup nodes?
4. does piranha only support http and ftp?
5. do I need to create common login for load monitor so that piranha could login to real servers and check the load ?
6. what is the hardware requirement for piranha to run on heavy loading site? I am using VMs all the time.

View 1 Replies View RelatedI am using centos with two physical LAN cards. Some times one of our internet link goes down so the entire network stop. Now there are two different ISP internet lines coming into a single computer in their respactive lan cards for load balancing.
Kindly guide me that how can I enable Load Balancing in my Linux Box.
If one ISP goes down the load balancing server will use teh second one and vice virsa.
I'm trying to setup a Centos 5.6 Squid Proxy Server with Content Filtering & Antivirus Scanning Incoming HTTP Traffic from the Internet
I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??
Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??
I'm a newbie on Ubuntu, I have a problem with squid proxy. I'd like to configure a system, include:
- a server is named ProxyServer that is installed Squid proxy.
- three servers, are named FTPServer01, FTPServer02, FTPServer03. each server is installed vsftpd.
- Clients are installed Filezilla to up/download resource.
All servers are managed by IP address. When a client request a resource, client connect to ProxyServer, this ProxyServer will switch to one of Ftp servers. I do not know how to configure the squid's config file to setup them.
we have an ubuntu server (10.04 LTS) with apache2 (2.2.9) and mod_proxy + proxy_balancer enabled.Reverse proxy works greatly, but I can't get load balancing working. Apache connect always to first member.
My configuration is as follow:
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Proxy balancer://test>

I would like to say first and foremost that I have tried to lookup what I can find about this thing I am doing and most of the time all I have found are either un-replied posts or vaguely explained answers but here is what I want to do.I want to setup a small gateway for my new office using two 3G internet providers offering Huawei usb modems. So I would like to have two internet links active per time and have one LAN consuming from the two links. I have seen the phrase Load Balancing all over the place but they all show their examples using ethernet and static IP's. My providers give DHCP ip addresses so is there anything I need to know and can anyone point me in the direction of some tutorial or howto i can follow to do this?

We have two offices suppose A and B. At office A, we use centos 5.3 computer as router and squid proxy server. At office B we use a cisco router to connect to Internet. Computers at office A that has direct access to Internet can access computers behind cisco router at office B using vnc viewer. But computers at office A that can use internet only through squid proxy can't access computers behind cisco router at office B. Is there any way so that I could allow squid clients to access computer behind cisco router at office B using vnc viewer.

I already setup the load balancer and two servers behind it with this kind of topology

The problem is when I try to hit the 192.168.1.1, it sometimes give me a HTTP 200 and sometimes it will timed out. I hit it using lynx -dump. It should return "Hello world!" if success. But if we hit it directly to 192.168.1.2:80 and 192.168.1.3:80, it will return HTTP 200 which means no error and no timeout. Since the Server 1 is the same as Server 2 in configuration, are there somethings I missed here?
Another information is that I set the director using round robin algorithm, so everytime a successful hit returned from server 1, the next one is surely heading to Server 2 right? Based on the Apache's access log, I also knew that the timed out occured only when it is the Server 2's turn to handle the request. Aside from the same httpd.conf and the same httpd version are there any things in the system level, kernel level that should be the same between those two servers?

I have 3 machine each one is running ftp daemon(example), and have an application daemon which is monitoring load and can communicate with remaining servers. now for every new connection I can check load of each server and I want to redirect that socket connect request to least loaded server. that load balancer daemon should be able to do this at runtime without breaking any existing communication. This should work seamlessly with any application. How I can achieve it using any combination of Advance routing, VLAN, iptables LINUX.
View 5 Replies View RelatedI'm trying to set up load balancing using iproute2 following this guide. I've got 4 dsl links as follows:
eth1 - 100.100.100.1
eth2 - 100.100.100.2
eth3 - 100.100.100.3
eth0 - 111.111.111.111 (main uncapped line)
eth0 is the default route, and eth3 is being used for something else. So what I want to do is load balance browsing between eth1 and eth2. I've added all of the routes in the LARTC guide, but the command to enable the load balancing:
Quote:
ip route add default scope global nexthop via $P1 dev $IF1 weight 1 nexthop via $P2 dev $IF2 weight 1 obviously involves creating a new default route. Since I'll be using Squid to push the traffic through the relevant line, how can I set up a load-balanced link for eth1 and eth2 without changing the existing default route on the server?
