Can someone point me for good VRRPD (rfc2338) implementation on linux. Some stable and live project Thanks _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hi. Is anyone using conntrack-tools to implement gateway failover on a network with windows clients? I set it up with ucarp and keepalived, and found that gratuitous ARP doesn''t always seem to update the cache on Windows machines. It works the first time, but if a second failover happens, the client continues to send stuff to the wrong MAC address. Linux machines work fine.

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 -- you don''t need eyes to see

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

Hi, Please suppose following config: Two external interfaces for two different providers On each of them configured NAT for specific IP addr. ie. 4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc htb qlen 100 inet 1.1.1.30/30 brd 1.1.1.31 scope global eth2 6: eth4: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc htb qlen 100 inet 2.2.2.66/27 brd 2.2.2.95 scope global eth4 On eth2

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. With this

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. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \

Hi, I have HA firewalls configuration (keepalived) on one site. Each firewall has its own IP and a Virtual IP (VIP) that keepalived activate on one of the firewall (active/passive HA configuration). I think I can set all two firewalls with same configuration, generating key pairs on one firewall and copying that to the second, so the remote host can see always one of the other firewall as the

Hi, list, I'm going to deploy postfix + dovecot + CephFS( as Mail Storage). Basically I want to use two servers for them, which is kind of HA. My idea is that using keepalived or Pacemaker to host a VIP, which could fail over the other server once one is down. And I'll use Haproxy or Nginx to schedule connections to one of those server based on source IP( Session stickiness),

Hi System debian 8.11 and dovecot-2.2.36.4 My webmail is roundcube with imapproxy. I have one problem. My dovecot servers is are in a cluster with keepalived like: dovecot1----VIP-IP--------dovecot2 All works fine I have a problem with imapproxy when a server dovecot1 had a problem (kernel panic sic!) Keepalived works perfecty and moved VIP to dovecot2 - all works fine for normal users but

Hey guys, I'm trying to install keepalived 1.2.19 on a centos 6.5 machine. I did an install from source. And when I start keepalived this is what I'm seeing in the logs. It's reporting that the VRRP_Instance(VI_1) Now in FAULT state. Here's more of that log entry: Sep 29 12:06:58 USECLSNDMNRDBA Keepalived_vrrp[44943]: VRRP Instance = VI_1 Sep 29 12:06:58 USECLSNDMNRDBA

Hi, how can DNS reliability, as experienced by clients on the LAN who are sending queries, be increased? Would I have to set up some sort of cluster consisting of several servers all providing DNS services which is reachable under a single IP address known to the clients? Just setting up several name servers and making them known to the clients for the clients to automatically switch isn't

I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This

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.

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
