gateway failover with linux
Hi.
I''m wondering if there''s a good way to configure a Linux firewall box to
failover to a single backup server, while preserving connection state.
This question has been asked before, but the latest reference I can find
is from 2004, at which time Linux had no equivalent of OpenBSD''s pfsync,
though Harald was said to be working on one.
Did anything come of those

Hot Fallover
Hello List:
Recently our shorewall FW server went dead (PS failure) & brought the entire
system down. Luckily we are testing the FW and other servers, so we did not
loose anything. Now we have decided to setup two Shorewall FW servers with a
primary & another fallover FW server.
I have done some research cruised the Internet and found that a product

High-Availability shorewall
Hi all!
I think I remember there have discussion on this topic on this
mailinglist a while ago.
But the archives don''t find anything.
Did anyone here set up a configuration with shorewall and heartbeat
or vrrpd or ucarp?
What would you prefer? Any experiences with failover times, setup
problems etc? Good documentation on this?
Thanks,
Christian

shorewall question
I am currently using shorewall on leaf-bering. I have set it up with
keepalived to create a high availabilty firewall cluster. I have an odd
question in regards to shorewall. Currently in production I have
keepalived controlling shorewall starts and stops. If I remove this and
leave shorewall running on the backup firewall, will I run into any
problems with having the nat tables built out and

shorewall, ucarp & conntrackd on debian

i''ve not found many hints on shorewall/ucarp/conntrackd topic. i''m
sharing this with the list, so that i''m able to search and find it the

What failover solution for advanced router ?
Hello,
Could someone experienced suggest good solution for failover
advanced router ?
The router for which I need redundancy is quite complex:
1) has 5 interfaces
2) uses the same network and the other network IP aliases on some interfaces
3) uses bunch of policy routing rules
4) uses proxyarp feature on some interfaces
5) uses complex iptables setup [propably not important in this

Multiple resource definition error
Hi,
So, I am writing a module to install and configure ucarp. There is only
one module in puppet forge and that is not that good.
In ucarp, same configuration files have to be served on two servers and
to configure the host I am defining a custom resource
ucarp::host::config. So, for using, I''ll have to create this resource
two times on two different servers. So, this resource

Firewall failover
Hi all,
We are investigating on firewall failover design. I have searched the
net and found that projects like LVS have it mostly solved for their
side but that netfilter lacks it.
Of course, a simple failover of the firewall is available using things
like VRRP (KeepAlive software) but without state syncronization, and
that is preciselly the part we need to investigate.
Is this issue

NFS with UCARP vs. GlusterFS mount question
Morning Folks,
should I prefer NFS with UCARP or native GlusterFS mounts for serving the
system images to XCP?
Which one performes better over 1G network links?
NFS is probaby easier to setup due to existing tools like rpcinfo and
showmount, both are used inside the storage container code, and there is some
code for NFS, not for GlusterFS, except I write one.
UCARP has the disadvantage that

GlusterFS failover with UCarp
Hi,
we've successfully configured GlusterFS mirroring across two identical
nodes [1].
We're running the file share under a Virtual IP address using UCarp.
We have different clients connected using NFS, CIFS and GlusterFS.
When we simulate a node failure, by unplugging it, it takes about 5
seconds for the CIFS and GlusterFS clients to refresh the connection and
continue operation. The

The Shorewall list server is back on line
There was a lengthy power failure here in Shoreline this morning and my
firewall did not come back up when power was restored. The firewall is
now up and service to the server has been restored.
