Dovecot, description and more is here at the homepage: http://www.dovecot.org/ Basically it provides IMAP and POP3 support so its an alternative to Courier in your config... Andy.

Are those connected to internal disks or external shelves? If external would you mind sharing what product you use? thanks Andy.

Fair enough, that sounds like just a limitation of that particular product. To support SATA it not only needs to be able to handle the tunneling but it needs the physical SATA connectors which it would seem logical isn't offered in every product... thanks Andy.

I guess you'd be restricted in ARC size due to running i386 (as opposed to amd64) but other than that I don't see why it wouldn't work. However PAE should be, according to the FreeBSD documentation, "considered beta quality" so bear that in mind. There are a few other comments on it here...

Hi, are you installing most things to /usr/local? In that case the easiest thing is just create a symlink from /usr/local to /home/usr/local (or whatever name you want under home). Otherwise, unmount /home, destroy the parition and create 2 new partitions using that space, say 10GB and...

I'd like to be able to connect a large number of disks without millions of cables and PCI cards, we have been using SATA PM disk shelves. I am seeing a few reports of poor reliability of SAS expanders with SATA disks, but on (open)Solaris. Anyone aware of any stories of how stable this is on...

Hi Phoenix, thanks for the info. Interesting what you say about SAS expanders, in wikipedia it says that SATA devices can be connected via SAS expanders whereby the SAS expander will communicate over STP to the SAS HBA. Perhaps this isn't implemented in the drivers in FreeBSD yet?? I had been...

Ok, answer to how does a SAS HBA communicate to SATA devices is explained here: http://en.wikipedia.org/wiki/Serial_attached_SCSI I assume both of these methods are supported in the mps driver, can anyone confirm? thanks Andy.

Yeah, as far as I know there is no difference in compression (algorithms etc) between any ZFS versions so I don't think its a reason to move to STABLE... WRT ZFS v28, for those that normally run RELEASE, a month or two more and we should have FreeBSD 9 that will be running ZFS v28. cheers Andy.

Hi, I am looking to replace some eSATA connected storage with something (mini)SAS connected. But I'm asking myself how does this actually work. The LSI2008 based cards seem a good option, how does the MPT driver handle SATA disks, does it effectively switch to SATA mode when it sees SATA...

Hi, I have setup a standby mail server using ZFS with ZFS send/receive and MySQL replication for SMTP/IMAP/POP3 config (Exim and Dovecot). Replication runs once an hour, though I could easily run this every few minutes if I wanted. If the first server goes down I have a live copy of the data...

Try grep <interface> /var/run/dmesg.boot ta Andy.

Well you cannot connect putty to your server if it does not yet have an IP address (ie before the IP is configured during boot). You need either a serial connection (which could be via a network connected serial concentrator) or some kind of remote access interface as you will find (as an...

Hi, Firstly is the new disk still connected? Why is zfs telling you it is unavailable? If you can get the disk online then you simply need to copy your data, then as Sebulon says, destroy the pool and start again. Trying firstly with zfs send/receive would be a good idea, if that doesn't...

As I said, I don't think you will see the squid port with tcpdump when running in transparent mode as traffic will arrive from clients on port 80 (which you should be able to see). If you can see traffic arriving on port 80, but its not hitting squid then it would seem an ipfw issue so you need...

Hi, firstly, as I mentioned, if you didn't install via ports then I'd recommend that method as its a pretty good guarantee that the app will work, ie install via "make install" from /usr/ports/www/squid30. WRT tcpdump, you definately should be able to see traffic in both cases even if...

It shouldn't be necessary to run configure manually, go to the port /usr/ports/www/squid30 and run make install. You will get a list of options to choose from before it installs which includes the option for ipfw transparent mode. What are you looking for in tcpdump? I think all you will be...

Just had a quick look, in ports the squid package has no transparent option for IPFW (it supports PF and IPFILTER). However there is a newer version, squid30, that does include as an option IPFW so maybe you should give that a go...??

Here is some more info: http://wiki.squid-cache.org/ConfigExamples/Intercept/FreeBsdIpfw Includes how to setup ipfw and also mentions that you need to ensure that you compile squid with the transparent proxy option....

Use tcpdump for basic are packets passing through the server test, for squid check the squid access log?
