Clean up WSUS space usage

See your server with too much space used by WSUS?

This link has a good method
https://social.technet.microsoft.com/Forums/en-US/278dfa59-aba4-4442-bbbe-6cd68fd725d8/sbs-2008-wsus-content-folder-is-over-20gb-how-do-i-decrease-this?forum=smallbusinessserver

The nut is this, by SuperGumby, quoting:
  • You'd probably each do well to open up the standard WSUS console, Updates, All Updates, and expose the supersedence column (rt-click on the column headings to do so).
  • Set 'approval' to 'any but declined', set 'status' to 'any', refresh the list, and sort by supersedence.
  • There's probably a few thousand updates in there that are either 'superseded' or both 'supersedes and is superseded'.
    Decline the lot (of superseded), run the cleanup again.
  • You have to look closely at what the cleanup task says about cleaning up superseded updates to understand why these are left alone.

Another Nostalgic Trip

Threw out files for a variety of older OS/Networks:

Novell
2.0
3.11
3.12
4.2

Lantastic
6.0
95
etc

Old Time Viruses

Have dealt with a bunch of viruses over the last 20+ years.  While clearing out old files, came across a few- and wanted to list them for posterity

Nimda
Funlove
Sircam
Worm_gone.A
Haptime
W32.HLLW.Hai
VX95.MTX
I Love You
XM/Laroux
VBS Network Worm=VBS_Netlog

Then found some more old files:
W32.Welchia.worm
Bugbear
Klez
IRCTrojan
Opaserve
PurityScan
Happy99
Sircam
Goner
Loveletter
Pretty Park
Magistrate
Navidad
Kak
MTX
Qaz
Sobig
Hybriz

And Finjan had mention of a Russian exploit of an Excel Call, fixed by some service packs.

I looked up up a couple, and Happy99 is considered the first virus to get transmitted by email.

Here's a summary of viruses and timeline at wikipedia

VOIP and testing

The following sites use Visualware's java-based diagnostic.

8x8
Probably the best implementation because, besides being the most complete, allows you to configure how many voip lines to simualte
http://voiptest.8x8.com/

Voip Quality Test
has an addition (top tab) diagnostic for SIP, RTP, etc
http://www.voipqualitytest.com/

SIP only at onsip.com
http://www.onsip.com/tools/voip-test

Note: check the + (Advanced) tab to see results like jitter to and from your site.

Freemind

I'm not sure the use or value of this, but I may want to investigate.
