Yes, it's about time for me to have a blog, too, I guess. I call this one a shoutblog, it's an XMPP bot I can easily talk (and hence post) to.


Last year I tried to setup several VPN solutions on FreeBSD, failing at each of them. Then Uwe pointed me at sshuttle which is easy to get up and running (and which totally rocks)!

Implementing ZSTD in OpenZFS on FreeBSD. So, is this a thing now?

Hm, seems like it: FreeBSD review: D11124

A friend of mine has a email address. Turns out, we're blocked by them: Connected to but sender was rejected. Remote host said: 550 5.7.1 Unfortunately, messages from [] weren't sent. Please contact your Internet service provider since part of their network is on our block list (AS3140). You can also refer your provider to . []

That surprised me a bit, but what do I know? So, I went to see who else did blacklist us: Blacklist Monitor Report -

No one else. Oooookaaaaaayyyy?

So, I tried the URL given in their SMTP response . I don't see any reason for blocking us, as none of their error codes is stated here. We also use SPF:

$ host -t TXT descriptive text "v=spf1 ip4: a mx -all"

After a bit of searching I came across Office 365 Anti-Spam IP Delist Portal

Fun fact: This site sends a confirmation email which is dropped by our (very standard) SpamAssassin with a score of ~11.x (5.0 being required for being identified as spam). 🤦

Some more digging around led me to the Microsoft community forums, i.e. Delist IP from Hotmail Block List … my overall impression of the discussion is this: Microsoft's blacklisting process is utterly intransparent and they don't have any working process in place to help you getting delisted - if that's possible at all, which seems to be highly questionable.

Now that's what I call a Hacker. I fail to see what's so special about this guy, though. :-p

It's been 3 years now that I switched from my former EBS TD 650 amp to a Kemper Profiler Power Rack .

Regarding equipment, that decision was one of the best I made. There are already a lot of positive testimonies spread all over the Internet regarding the switch to Kemper, mostly regarding its spot on sound compared to the profiled amps, and I certainly won't object here.

However, what's also extremely great and which doesn't get mentioned that often, is its exceptional range of high quality effects. From noise gate to EQs, boost and distortion, flanger, chorus, etc. almost everything is top notch quality.

One must also point out how well thought the user interface is! Every refinement to it (there are constant upgrades) is also an improvement. Most of the time these improvements tend to suprise me, as they ease certain aspects that I didn't find lacking, but which address these aspects in a way that make them even more accessible.

Recently, I got a Profiler Remote which is yet another testimony to the exceptional quality Kemper delivers. Apart from its sturdy construction, using PoE for having just one cable to care about isn't just great, it's perfect engineering.
