RFC4226 and RFC6238 Test key QR codes

Having only recently discovered the glory of OATH two factor authentication I finally got around to setting up one time passwords on my SSH server tonight.

For some basic testing on Time based One Time Passwords (TOTP) I was using the RFC6238 test key and was a little annoyed that putting in RFC6238 Test key QR code didn't bring it up right away - so here it is for my easy reference in future!

Troubleshooting Windows Server VSS issues without rebooting

After being told by our backup crew that I'd probably have to reboot any Windows servers with VSS issues I had a look through all the information I could find. Alright, I should have read about this in 2003 odd, but it's not really my field of IT expertise. Having collated and written up some notes for work it seemed a shame to not post them here.

Cage Match - Gluten vs Holy Communion

I passed a local church yesterday and was quite surprised to see a their huge motivational board proudly proclaiming "ALLERGY / GLUTEN FREE COMMUNION BREAD". That got me thinking... a dangerous activity while driving. If communion magically transforms communion nibbles into the actual body of a Christ, wouldn't it be gluten free anyway. Today Google/Wikipedia sucked me down and into the rabbit hole that's the swirling vortex of Christian dogma. If I'm going to have my brain explode into confused lumps I want to share - so here we are. What we have here is the Catholic tradition of the Eucharist, followed to varying degrees in other Christian sects. The wafer and wine are blessed and undergo Transubstantiation - transforming into the body and blood of Jesus. It turns out that it's not as simple as the communion wafer actually turning into the physical body of Christ. I mean, you can test that sort of thing. The wafers would go all floppy - unless it's ...

Revenge of SMFIC_BODYEOB reply packet header

My old friend SMFIC_BODYEOB  put in another appearance today. Or, more probably, the last six months and I haven't noticed. Jan 12 16:41:20 myserver postfix/cleanup[4860]: warning: milter unix:/spamass/spamass.sock: can't read SMFIC_BODYEOB reply packet header: Connection timed out GAH! I thought I'd fixed this. Off to the /etc/default/spamass-milter I ran. No obvious problem... Next, head scratching. Then, comparing to my test server, I added in "-d spamc" to the  OPTIONS line - which shows input/output to spamc in the mail.log Sure enough - although spamd was returning a result in about ten seconds (not especially speedy, but it is a Pi) spamc was taking five minutes to return those results to spamass-milter. By then Postfix had given up and delivered the mail. Jan 12 22:46:03 myserver postfix/smtpd[3108]: connect from localhost[127.0.0.1] Jan 12 22:46:03 myserver spamass-milter[2979]: output "X-Envelope-From: <ldhsnvf@ca-se-visite.fr>#0...
