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.

NFS vs Replication
Hello list,
I built an email system using a proxy / director pair (IMAP, POP3, LMTP)
and a backend pair.
To have an HA system, I would like to understand if it is better to use
an NFS export or replication to save emails and index files
NFS is provided by a NAS (in HA), while for replication I would use the
local backend disks
Which of the two systems is more reliable? Are there any drawbacks

NFS vs Replication
Thank you all for replies!!!
Some missing infos...
- As load balancer I'm using a pair of keepalived with simple setup and
not the DNS
- Load balancer algorithm is "Weighted Least-Connection"
- About 20 domains and 3000 email
- I'm monitoring my backend servers with poolmon
- The backend servers are virtual machine (vmware) with datastore on
"all flash" storage

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 Ganesha HA w/ GlusterFS
Hey Guy's,
A success story instead of a question.
With your help, managed to get the HA component working with HAPROXY and
keepalived to build a fairly resilient NFS v4 VM cluster. ( Used
Gluster, NFS Ganesha v2.60, HAPROXY, keepalived w/ selinux enabled )
If someone needs or it could help your work, please PM me for the
written up post or I could just post here if the lists allow it.

Sounds good and no problem at all. Will look out for this update in the

Was looking for a sense of direction with the projects and now you've
given that. Ty. Appreciated!

keepalived on centos 3.4
Is anyone successfully using dag's keepalived-1.1.10-1.1.el3.rf on
centos 3.4?
It's giving me some strange issues (LVS Topology never shows up, even
though I can manually set it w/ ipvsadm)
Attempting to rebuild it has been less than successful, as anyone who
tries will see in their appropriate BUILD/keepalived-1.1.10/config.log
and in the rpmbuild output. It complains about openssl

Dovecot cluster using GlusterFS

doveadm + HA
Hi
I have two server directors in ring and 5 dovecot servers (2.2.36)
IP for IMAP and POP3 is a VIP (keepalived)
What is the best solutions to get realy HA for 5 dovecot servers ?
Maby corosync+pacemeker ? But this solution is too problematic and hardcore
Why I need HA ?
Doveadmin is too lazy and doveadm director does not know that one
machine broke down and still sends traffic

HA firewall with tinc
I have 2 firewall in HA with keepalived. Can I use active the same tinc configuration on 2 firewalls ? using tun Interface with same ip on all 2 nodes is a problem ? tun device advertise itself on the network having an IP/MAC pairs (ARP) or the IP is only used by the system internally for routing so using the same configuration is right ? so one firewall be active, the other is passive.

Don't use a backup MX, they are a relic of the 90s when mail servers
were often times not always online. a sending mail server will
