Atro Tossavainen

UNIX Dinosaur and Techno-Amish

Welcome. As you have no doubt already figured out from the sparseness of these Web pages, I'm not a web designer.
I like lean things that do what they were designed to do, and do it reliably. Hence, I am:

• a Linux/UNIX administrator
  with professional experience of more than two decades on
  • Red Hat Linux (5.1 to Enterprise 8, currently)
  • ...and the history department...
  • Solaris 2.6 to 10
  • AIX 5.3, 6.1, 7
  • IRIX 5.3 to 6.5.30
  • DIGITAL/Compaq/HP OSF1 == Tru64 UNIX 4.0, 5.1
  • HP-UX (9 and 10.20)
• a backup administrator
  with professional experience of more than two decades on
  • EMC/Legato NetWorker Save/Restore (aka Sun Enterprise Backup System) on versions 5.5 to 9.2 inclusive
  • ATL, IBM, StorageTek and Qualstar tape libraries
  • EMC Data Domain deduplicating disk backup
• a SAN administrator
  with professional experience on (in chronological order...)
  • Compaq RA8000
  • EMC CX300 and associated Connectrix FC switches
  • Apple Xserve RAID :)
  • HP MSA2012fc and associated Brocade 200 series FC switches
  • NetApp FAS2040 and associated Brocade 300 series FC switches
  • IBM SAN Volume Controller and IBM DS series storage
  • NetApp FAS3240 MetroCluster
  • Brocade 4100, 5300, 5140, Fabric OS up to 7.3
  • NetApp V3270 virtual filers + MetroCluster
  • EMC CX4
  • IBM/Lenovo Storwize V7000, 5030 and 3700 series
• a qualified engineer, having graduated from the Espoo-Vantaa Institute of Technology (also later known as "EVTEK University of Applied Sciences", and now, "Metropolia U of A S") in 2007

In addition to the strictly professional items above, I am also

• a singer
• a guitarist, a bassist, sometimes even a drummer
• an audio recording engineer

Them New Digs

OK, I did what I thought I'd never do, I gave in and got myself a vanity domain just so that I can host my own mail following the implementation of Lex Nokia. (Things snowballed and I formed my own business and took a leave of absence from the Uni.)

So here it is, and addresses of the form something@atrotossavainen.fi work now. The expected userid I've got everywhere else and the obvious first.last alias work, of course. Messages sent to that explicit address in the beginning of this paragraph will be submitted to spam blocklists.

In addition, having this allows me to tag incoming mail - also with services that violate RFC 5322 Sections 3.4.1 and 3.2.3 (and thereby the corresponding sections of the superseded RFCs 2822 and 822) by disallowing the use of "+" in the left hand side (of the @, that is) of an email address.
