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

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

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. I've configured tcp and udp port 53 with the piranha gui, set up
arptable rules on the real servers and added the virtual ip to the bond0
interface on the real servers, but I'm still having no luck in getting

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)
Hello fellow samba users,
Our company uses samba for all fileshares/printing/PDC on
two SUN E3500's. We like to replace these with about 10
Linux 19" XEON (pizza)boxes. The question: Are there
any implementation out there using a loadbalancing cluster
doing samba?

Shorewall and LVS-NAT (via fwmark) nat'd machines can't access the outside world directly
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.

Skel VFS module crashes smbd when we have no ACL support in samba v2.2.9.
Hello!
I have compiled samba v2.2.9 without ACL support and when I test skel vfs
module I have encountered internal errors (SIGSEGV in child processes).
Consider the file source/samba/vfs.c:

[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.
