Hi all, I've 4 servers with dovecot and ldap authentication behind a loadbalancer (Alteon). To connect to dovecot, client need to use a vip of the loadbalancer. To connect to the ldap server, dovecot need to use the loadbalancer cause there are several ldap server. The loadbalancer close a connection without activity during 30mn Dovecot lauch several authentication process who have

We have quite a few frontend mail gateways that deliver incoming email trough our dovecot director (lmtp proxy) to the backend lmtp servers, and are seeing this logged on the frontend mail gateways: Sep 5 10:51:56 mailgw1 postfix/lmtp[23443]: 0E2F41C01A: to=<me at example.com>, relay=loadbalancers.example.com[192.168.42.15]:24, delay=61, delays=0.02/0.3/31/30, dsn=4.4.0, status=deferred

...It's probably the best idea to direct SMTP and POP/IMAP always to the same server behind the loadbalancer (because dovecot-deliver is used which updates indexes?) - If we think of a "active/passive" setup: dovecot index-files locally or on the nfs-share? - Is it possible to activate loadbalancing for SMTP in this environment if dovecot index-files are held locally on each machine (POP/IMAP is directed only to one of the two servers?) Any comments welcome :-) Werner

...------------- | router | eth0 ------------------ eth0 | router | | linux 1 | | linux 2 | | | eth1 ------------------ eth1 | | ------------- ------------- I''d like to do per packet loadbalancing on linux1 and linux2 routers. How to configure each one? I think, the Julian Anastasov patches from http://www.ssi.bg/~ja/#routes are unnecessary ??? Regards, -- Michal

Hi list, Is it possible to have NFS based load balancing and failover enabled storage without stacking switches? Or is this only doable with iSCSI and multipathd? I''m reading about XenServer and openvswitch, how multiple VMs would be able to use all physical links using SLB bonds, it works for networking but not for storage? (As the nfs share is mounted on dom0?) Using openvswitch

...enario: a firewall with one lan interface eth0 10.1.1.1/24 and two uplink interfaces eth1 10.2.2.1/24 eth2 10.3.3.1/24 each uplink interface does SNAT: iptables -t nat -I POSTROUTING -o eth1 -j SNAT --to-source 10.2.2.1 iptables -t nat -I POSTROUTING -o eth2 -j SNAT --to-source 10.3.3.1 i set up loadbalancing multipath routing as described in the howto. then i had the well mentioned problem that established connections leave the wrong interface after the routing cache clears. i solved this using the CONNMARK target, marking connections which left one interface and directing those packages always to the...

Hello, i wrote a simple but useful (i hope) bash script featuring a easly and fastly configuration method for implementing a Linux Gateway feauturing Incoming/Outgoing MultiHomed/LoadBalanced Subsystem Management. I want share this little script. you can download a copy from the following address: http://www.initzero.it/products/opensource/izbalancing/download/izbalancing just save it in your

If I could do that , maybe I could find the way to loadbalacing n line ADSL as one biger . If someone know how to or have some idea , give me some info...

Hi Folks, I'm trying out some ideas for loadbalancing Samba servers with some replication underneath. Right now, we're trying to use DNS round robin, just to see if it works, but it isn't. Our basic config is that we have the same share and NMB server name on every node. Each node has a different IP hostname, which are all round-robin'...

Hello Mongrels, Building on the last messages about Fastthread, can we get a detailed survey of the different ways people are deploying their applications? It will help with near-future Mongrel development. Please include the following things: * Framework, if any (Camping, Merb, Rails, Nitro, Ramaze, IOWA, Rack...) * Mongrel version * Mongrel handlers used (rails, dirhandler, camping,

Hi, I have the following setup. Two linux systems with two [test] external interfaces encrypted with ipsec [transport]. Two gre tunnels that pass 10.200.0.0/24 and 10.200.1.0/24 network traffic. Testing the balanced tunnels I would setup iptraf on one and ping from the other. The results would be as expected; traffic would be split between the two interfaces. Testing with an ftp transfer of

Hi, I have question i have loadbalancer that's connects every x seconds to my pop3 and Imap to see if it's still working. Every time it connects I see its ip is there a way to say don't log ip x.x.x.x ? With kind regards, Bas van den Dikkenberg -------------- next part -------------- An HTML attachment was scrubbed...

Hi folks, I've just been reading about the above command and wonder if anyone has made use of it for load-balancing or if doing so would be completely inappropriate!? I'm thinking of the scenario where there are a number of Asterisk gateways and incoming SIP traffic. From what I've read, with a box in front receiving all incoming traffic the SIPRedirect command could be used to

Hi, We have two internet connections and I would like to loadbalance between the two using advanced routing. The gateway machine to my lan has two interfaces, one connected to lan(eth0) and other to wan (eth1). The wan side interface is connected to a switch which is terminated with two internet connections from two ISPs. I have added the routes as follows, ip route add default scope

Hi~ My linux box(kernel 2.4.13; used for NAT) have 3 NICs, two of them are for ADSL(I have two adsl line) and the last is for private network. My ISP doesn''t support multilink. In this situation, How can I use both ppp lines for the internet(load shareing or balancing)? Thanks. Lee.

Hello All, I have a linux box running with three NIC''s, I have used brctl tool to configure this box as a bridge, i have given it ONE logical ipaddres, Every thing is working fine, but now i am required to configure the same bridge as a LOAD BALANCER.... On some googling i found the following link http://lartc.org/howto/lartc.rpdb.multiple-links.html This HOWTO requires me to have one

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC

Hi, Is there a way for dovecot to use a pool of sql (mysql) servers and load balance queries between these? Also fallback to next available sql server if connection to previous one fails. Can dovecot do such things currently? (If not this is feature request). -- Arkadiusz Mi?kiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/
