Using Shorewall + Linux Virtual Server LVS/DR
I''m havign a HUGE amount of difficulty getting shoreline to work with LVS. We use it here constantly so we know it works. The problem is packets come in, get directed to a webserver, webserver returns the packet to firewall, and then it goes into a black hole. rp_filter is off globally on all interfaces. LVS seems to be working right.... I use shorewall tcrules to mark packets on

load balancing 20 asterisk servers
I've read several other emails and pages on the wiki but none give any deffinate answers. if you have 20 asterisk servers each with 4 pri's, all running RealTime Extensions and RealTime SIPBuddies from the same MySQL server, what prevents you from putting all 20 servers behind a single load balancer? That way all of your UA's can use the same IP to register to; vs maintaining which

anyone care to point me in the right direction? LVS
i'm trying to setup LVS, and tried both the lvs-dr and the lvs-nat, but can't get any to work. I'm hoping people here can answer a few questions that might help and shed light onto the situation? #1 with regards to the Real Servers, is there anything that needs to be configured other that the http service? I ask this, because I suspect yes, and it has to do with what type of LVS you

Apache/Cluster issue -- Single public IP address
I want to set up a cluster that is used for web hosting (RHCS cluster). Recently, I experimented with a 2 node cluster and was able to run it successfully. However, I have started facing some issues with Apache, which I had configured as a service using the Cluster configuration tool. To do this Apache needs a floating IP address. This address is in addition to the network interface IP address.

simple load balancing/failover for OWA
We are building an exchange cluster with two front end Outlook Web Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them. The MS recommended way is to use NLB, but for various reasons that's not working with our set up. We are looking to set up a single linux server and use something like LVS to load balance/fail over the

Again: Workaround found for request queuing vs. num_processors, accept/close
Hello all. I too found out that I sometimes have some action that can take up to 10 seconds in my rails application. I''ve read all arguments Zed made about polling/and inbox strategies, and I think I just can''t work around my feeling that a "wrong" request that takes up too much time should be able to lock subsequent requests in mongrels queue. That''s what

Setting Up LVS to Load Balance DNS
Greetings, all: OS: CentOS 6.4 x86_64 Kernel: 2.6.32-358.14.1 I could use some assistance with setting up pulse to load balance my dns servers.

Monitoring IP masquerading on LVS load-balancing
I've got small numbers of connections moving through a load balancer configured in NAT mode. So I've got an iptables table called "nat", which has in it a line "-A POSTROUTING -o eth0 -j MASQUERADE" (lan connect is eth0, private lan inside the cluster is eth1). The load balancer is working; connections made to the virtual ip on that host do get routed to one of the

Samba using Virtual Servers (load balancing)

Hi guys, I''m not sure where to post for help on this one, shorewall or lvs, I''ll start with shorewall (only cause Tom is a gun at this stuff, and is polite enough to tell me to bugger off to the LVS list if I''m posting in the wrong one ;) I have a single box that is my router/firewall/LVS.

[PATCH] lvm: support lvm2 older than 2.02.107
lvm2 2.02.107 adds the -S/--select option used in lvs to filter out only public LVs (see RHBZ#1278878). To make this work again with versions of lvm2 older than that, only on old versions filter out thin layouts and compose the resulting device strings ourselves. The filtering done is much simplier than what "-S lv_role=public" will do, but should be good enough for our need. ---
