You should check out the rsnapshot port. it does what you are looking for
and more. It will save you a lot of scripting, etc and it works great. I
have been using it as part of my backup procedure for a while now and it
works well.

Can we no longer use make buildworld to upgrade from source builds? 
Everytime I've tried, I get build errors. I've gotten the impression 
from a few things I've read that freebsd-update is suppose to be used. 
I don't want a binary install/upgrade though. I've just sync from CVS 
with this in the config:


well i exactly upgraded this way. no errors.

same here. no errors on a few boxes.  do you have extra stuff in your 
make.conf file? if so, comment them out and try again

Hi all, I've got an older Solaris system running Sendmail for my
mail server right now.  It's about time to replace it, and I'm
thinking FreeBSD might be the best choice of OS for the replacement.

However, it's been some time since I looked into options for mail
servers.  I'm interested in both suggestions for hardware and mail
servers that would make for the best FreeBSD based mail server.

I've only got about two dozen users, though they are all very heavy
users of email.  I'm using IMAP, and I'd like to continue to do so.

Finally, we have quite a few aliases I'd want to port over to a
new server.

Thanks,



I like postfix + dovecot.  Easy to set up and both have a ton of 
features. any relatively modern hardware will do with that kind of volume.


your aliases shouldnt be a problem either.

Re: suggestion on a backup utility

I wonder if anyone can recommend a good backup utility for FreeBSD.
If it's in the ports, great. I would like to just specify which 
directories I would like to backup, how often and have it tar or zip 
the files into a directory - if it has off-site ftp, fine, but I can

do that part myself via crontab.

I realize I could just make a script file with some tar commands,
but I'm looking for something that is quicker to maintain and 
allows me to organize what I'm backing up.


I have been using reoback but recently I ran into some problems
with is duplicating files X 10! - I looked into to solving it but
it might be easier to just try something else.


flexbackup is pretty decent. i used it for a while before i just went to 
using dump on entire file systems.

At any rate, locking down ssh access is one of my concerns, for sure,

Wouldn't turning off password based logins and using public and private 
keys (with a strong password) for ssh logins do the trick? if you limit 
yourself based on IP addresses, its inevitable that you will need access 
from an IP NOT on your exemption list at some time (like when you are on 
vacation, at relatives, etc).


Using keys to authenticate ssh sessions has worked very well for me. if 
you are concerned about the brute force attempts (which cant work 
without the private key which you put a strong password on), you can use 
something like denyhosts to block those hosts from even connecting.

Are there startup scripts for these things in rc.d?
Putting something in rc.conf is only setting a flag or value
that scripts read up to see if they should run or not and what
values to run with.   Nothing actually starts (or shouldn't) from
the rc.conf file.

yes, the files are in the rc.d directory and start up properly when i 
issue the commands manually (ie #/usr/local/etc/rc.d/dovecot start).

I will give this a whirl and see how it goes. I have never had issues

I commented out the securelevel stuff as well.

Thanks for the suggestions. i will report back once i get the box rebooted

success! commenting out the securelevel resolved the issue.  i never ran

Server build config, what would you do?

2008-04-09 Thread Eric Zimmerman

Hello,

Can anyone recommend a solid motherboard for building a BSD server 
around? I would like at least a Core2Duo CPU, but would consider Xeon 
(single or dual CPU boards are fine).


The server will be for file storage and general services like email, 
apache, etc.  Not a ton of volume for either


I plan to use a 3-Ware or Areca controller (4 port). Does one of those 
work better than the other? I have had pretty good luck with some 3-Ware 
cards so far with FreeBSD, but have heard good things about the Areca 
cards too.


Heck, while we are at it, can anyone recommend some decent internal SATA 
enclosures with 5 or so slots?


Thank you for your time,

Eric

so why at least core2duo. for your case 50$ used computer (possibly with 
larger disk) is enough.

no special controller works best.


I'd like a C2D to allow for future growth and the fact that it will be 
serving files for several people on my home network not to mention the 
other services on it.


Why do you think no special controller works best? If that was the case, 
why would they even make hardware based RAID cards, or RAID cards at 
all? I have a solid backup plan in place, but why risk downtime when 
solutions are available?

Supermicro motherboard compatibility/Server recommendation help

2008-04-08 Thread Eric Zimmerman

can anyone speak to successes with using the newed Supermicro server
boards with FreeBSD? i was looking at things like this:

http://www.supermicro.com/products/system/4U/7045/SYS-7045A-CT.cfm

On-Board Devices
Chipset 

* IntelĀ® 5100 (San Clemente) chipset
* IntelĀ® ICH9R + PXH-V

SATA

* Intel ICH9R SB SATAII Controller
* RAID 0, 1, 5, 10 support (Windows only)
* RAID 0, 1, 10 support (Linux)


Does FreeBSD support that SATA controller for various RAID setups?

Does anyone have any suggestions for a vendor that provides barebones
servers (tower models) with hot swap SATA drives included?

Thanks,

Eric
