[CentOS] Mail Question
Hello everyone, Im having a issue that I just cant seem to figure out. We currently are running an email server Centos 5.6 Postfix/Dovecot with a squirrelmail frontend. I was setting up a testbed to do a migration to SoGo using LDAP/MYSQL/POSTFIX/Dovecot. I have everything up and functional but one thing is giving me an issue. The testbed box will not handle a users mailbox over 2gb. We are using mbox on the existing server with no issues at all. I have multiple users with inboxes over 2gb and and archive mbox file with over 50gb. I have check postfix and made sure that the mailbox_size_limit = 0 Both are running i686 as returned by the arch command and both are Centos version 5.6.

We have a couple mysql dbases, oracle database, smb shares, nfs, email, and web servers. Each app has it's own best way to provide the redundancy and auto-failover and it's own set of tradeoffs of the added complexity vs. the possible reduced downtime if the primary fails. I'd balance the options against the low-tech method of having raid mirrors in swappable bays with a spare similar server chassis or two around plus regular backups kept at a different location. The raid lets you continue in the likely event of a disk failure so you can repair it at a convenient time. Other failures (motherboard, power supply) are less likely but can be handled by swapping the drives into an alternate chassis (and with Centos you'll need to re-assign the IP addresses that are tied to the old NIC mac addresses) with a small amount of downtime. And the backups cover things like operator or software errors (that would wipe a cluster too) or a building-level disaster that destroys the disks or the primary and spare chassis at the same time. Some apps may be worth the effort to do better. -- Les Mikesell lesmikes...@gmail.com Currently we are doing the low tech method.

If you are looking at VMware, ESX(i) is the nicest of the bunch but moderately expensive for the full version that does clustering and live moves - and you also need a highly reliable iscsi disk server. But even the free version is very nice in terms of the management tools, low overhead, and the ability to overcommit the host's RAM. You could start by building shadow copies of most of your servers that could be activated as needed, with perhaps a few being live with application level failover (heartbeat, drbd, database replication, etc.). ESXi is also a nice lab framework for testing new thing. -- Les Mikesell lesmikes...@gmail.com When you talk about the free version are your referring to Vmware server or is there a free version of Esxi?

Bo Philosophically, I don't see how running on ESXi virtualization is any more or less proprietary than running on IBM (Dell, etc.) hardware directly. Unless you are just being pedantic about it, the main thing to consider is whether or not you could move your application elsewhere easily if you had to live without the unique proprietary features of any platform. And you can, if you pay attention to how things work. In fact there is some standardization being done in the virtual containers, and I'd assume VMware is a leader in that. -- Les Mikesell lesmikes...@gmail.com You make a valid point.

I just can't figure it out. Here goes. I have a bunch of users in a public library. Some are administrators: they handle the library, write the docs for everyone, etc. Then you have the agents, who take care of lending books and fetch them when they get returned. And then you have the odd anonymous user, using the PC with a guest account. Let's make thing simple and start out with one machine. Every single user has a /home/user directory. Plus, I added the following directories: /home/pub and /home/echange Then, I created two groups, administrators and agents. Here's what I'd like to achieve (but I think my IQ is just below the required limit :oD): 1) Members of the administrators group have unlimited read/write access to /home/pub and below. 2) Members of the agents group have read-only access to /home/pub and below. 3) All the others (that is, members of neither administrators and agents) have no access at all to /home/pub, not even for listing the directory content. The thing is: I can't seem to formulate my problem in terms of user/group/others, as there are no owners, but two distinct groups involved. Any idea how to crack that nut?

Capturing traffic using tcpdump while testing would confirm this, i.e. tcpdump -i any -n port 5071 would show packets coming in on eth0 and going out on eth1 if everything is working, or only coming in on eth0 if something within this box is preventing forwarding, or nothing at all which would show that the traffic wasn't even making it to your machine... d ___ I think I found the culprit but not sure if by taking this out it will be a risk.

My question is can you tell apache to point a subdomain to a diiferent IP address. For example, Our domain is currently amelia.k12.va.us.

I believe our largest installation to date is ~100 users or so. I would have thought that this was a small install:) Agree. If you need multi-servers for 300 hundred users something is just designed wrong. Unless you've got 300 intense power users. Even then... 300 users should fit on a desktop-class machine (provided you've got enough RAM). Zimbra uses Java / Jetty and thus likes to have enough RAM. On a single server, I'd go with at least 8 GB of RAM. Go with 64bit Linux (AMD64). CentOS is not supported, but it seems to work nicely or now... Rainer ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos My problem would be that a single machine is a single point of failure. We are looking at zimbra and using at least two machines utilizing GFS and our SAN so we can withstand a failure. We have around 75 users but I am not willing to have email down due to a single machine failing. (Btw, these would be virtual machines running on xenserver) Seeing as you are in education, if you are looking to actually pay for licensing a product and are actually interested in Zimbra, take a look at their hosted model. It is only for educational institutions right now (not that I know if they will make the offering more widely available) and may fit the bill even more by not having to manage the hardware. My biggest concern is the long term viability of zimbra with the possibility of MicroHoo or someone else picking up Yahoo in the future. I don't want to start something with that one, but for a business this is definitely a concern. I believe some of this has been addressed in their licensing language and there is always the the GPL version which would probably survive for at least a short while. Andrew We would definitely be looking at a app for free in other words zimbra's open source release. We are planning on using existing hardware that we have. Currently we are running CentOS 5.2 with Pentium D 3.2 with 2gb ram and 2 500GB SATA drives in a RAID. The motherboard that we have will support a quadcore xeon if needed. Are setup now has no probs but we are only doing basic email and calendar within squirrelmail itself.

We have it running on a system with several hundred users, primarily doing e-mail on a system with a single Intel(R) Pentium(R) D CPU 3.00GHz and 4GB RAM. My primary gripe with Zimbra is that it wants to take over a machine with its own versions of openldap, postfix, amavisd, clamav, etc., and these are not always kept current. We have one Zimbra system running as a VM under the free VMware server, allowing us to screen incoming and outgoing e-mail with current versions of amavisd and clamav before passing it to the VM for final delivery. Zimbra also works independently of the Linux user system, which some consider a feature, but I don't like as I like to be able to handle many things at the user's $HOME directory level. In particular we normally use courier-imap with Maildir storage, and our own server-side filtering and routing before delivery.

The point releases (5.0, 5.1, 5.2 etc) are simply snapshots in time of the CentOS 5 product life cycle where development was temporarily frozen just long enough to spin a set of install media. You should always get updates from 5 which is a link to the current (and only supported) release. This happens to currently be 5.2. If you were to get updates directly against 5.2 then when 5.3 is released you would get no more updates to CentOS 5 ever. This is why you should *never* link updates against 5.x and always 5.

I really appreciate it. -- Bo Lynch ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unfortunately, my ISP's plan uses dynamic IPs, so I have to enter various subnets to stay safe. :( If you do not allow password authentication and use good pass phrases on your identity, the only thing really gained by restricting on IP ranges is restricting the number of reject messages in your log files. The fail2ban program does a nice job of limiting the number of rejection messages in the logs. Another possibility is to set up OpenVPN on your system, which authenticates on ssl certificates and works nicely even from dynamic IPs behind NAT. Then you can ssh into the private LAN behind your firewall via OpenVPN. Bill -- INTERNET: [EMAIL PROTECTED] Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.

For a firewall, we basically have iptables with 2 nics doing NAT. So would the OpenVPN server live inside of our private network and just do some forwards with iptables on the firewall or would it be better to implement it with by itself with 2 nics one on the public and one on the private? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
