Solaris: July 2008 Archives

Obsolete - please use Version 1.3.1!

I just did a little upgrade to my vhci_stat-program, now showing also ZFS header data. The pool does not need to be imported for this task.

Example:

# vhci_stat -z
vhci_stat
1.3; Pascal Gienger <pascal@southbrain.com>; http://southbrain.com/south/
Host: seattle

Binaries for SPARC Solaris 10 and x86 Solaris 10 are included.

[Download removed]

More info is available on the vhci_stat-Page.

[This is obsolete, these binaries are included in the 1.3.1 vhci_stat-distribution: vhci_stat-1.3.1.tar.gz]



Due to popular demand, I made precompiled binaries for Solaris 10 on SPARC and x86 platforms, without any shared GCC libraries:

• For SPARC: vhci_stat-1.2.sparc10.bin.tar.gz
  md5: 3394723d4f12ca95f15848fc6fac22f4
• For x86: vhci_stat-1.2.x86_10.bin.tar.gz
  md5: 1c7fe153cb33f57a71783f39d0d3951a

First:

On our running Postfix-Graylisting Setup, the two MySQL nodes are quite loaded:

Uptime:                 1 day 8 hours 54 min 29 sec

Threads: 320  Questions: 20519246  Slow queries: 15205  Opens: 522  Flush tables: 1  Open tables: 516  Queries per second avg: 173.204

And this is the result of implementing graylisting:



But let's start from the beginning.

The scenario was like that:
Two mail servers are acting like an MX for an educational institution. 1.2 million spam mails came in per day. The two Ironport appliances behind did their best to sort them out, but in that institution spam cannot be deleted, there are laws against that. So the central cyrus mail server sorts them out via sieve scripts and puts them in the Spam boxes of every user, wasting disk space and - more important - disk i/o.

So I had the idea to implement a graylisting setup.

Each of the two Postfix nodes has its own MySQL database server running. But how to replicate data between them?
