Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Just a tiny post about my home Internet Connection. I use a Vodafone, former Unitymedia, CableMax 1000 home connection. That’s a Gbit Coax line with 50 Mbit upstream. Problem at the beginning of the new 1G Tarif there where several Problems regarding IPv4 / IPv6 – either you got a IPv4 only connection or something like DS-Lite or a SLAAC IPv6. I quickly figured out there is a way to change your contract and let them enable “Dual Stack”. ...

Unifi L3 Adoption Recently I installed a lot of new Unifi Sites in local Schools, due to Corona the demand of a working Wifi in School Environments boosted. Most sites we Setup run their Network split to different VLANs, so a simple Layer 2 Adoption is not always possible. But Unifi Controllers luckily have a way to solve this possible adoption issue. So I got used to set both, DHCP Option 43 and unifi DNS name on each site, no matter if VLAN (L3 Structure) or a flat L2 Network. I just set the Options and done. ...

Or my home Cloud without „the Cloud” :) If it comes to Syncing folders to several devices many of us go the “lazy way” using google drive, dropbox, onedrive whatever to sync your local Documents. Some may go a step further and use some kind of Encryption, but this is often not very end user friendly. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. I cannot point out often enough how critical it is to keep your internet-based Servers updated. I use and manage some Servers, about 20 currently. But I hate to check them on a weekly base for Security Updates. I still remember days where Sysadmins brag with uptimes – not a smart thing to do. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Yesterday I wanted to install a Game from Epic Game Launcher in Windows. (Spellbreak, btw.) Unfortunately even I have a 1G Line, it only dripped in with about 100-500 kb/s and would take several hours to complete. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Recently I moved from my old PI3B to an Intel NUC i3 as my “Home Server”. It has enough power to run all my local services and is still not wasteful in terms of power consumption and space requirement like a “real” Server, and it is fanless. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. If you run Letsencrypt SSL Certs on your servers and use certbot you probably know what I’m talking about. In the past I had it several times that the cert itself was renewed but the webserver, for whatever readon, didn’t reload. Causing the website to report a expired certificate, even it’s not. As soon as I did a manual NGINX Reload it workend. ...

TL;DR HoneySIP is a SIP Honeypot Blacklist for use in Firewalls to Block SIP Crawlers and Bruteforcer. All IPs coming from own SIP Validating Honeypots at several servers. If you run a Server accessible over the Internet you will quickly find a lot of “interested” Eyes on it, especially if it is a VoIP System using SIP on default udp/5060. In an Ideal World this system would never be exposed to the Internet – but if you have a PBX which need to be accessible by a lot of remote workers and know how critical SIP/RTP can be you want to avoid forcing SIP over VPN. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. There are several reasons, the most important one is that my old domain got some big hit and “Negative” Backlinks over the many past years. The old Domain solariz.de was registered more then 20 Years ago, in this Time I did a lot of changes on the Domain, CMS, files I hosted and so on. Those gave me a lot of different Backlinks from all over the World – you might think Backlinks are a great thing. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Cause I’m not „blogging“ regularly on this page I just want to post more things in a “Today I learned” fashion. Specially if you work on/at Events and IT there are a lot of things which leave you puzzled questioning thing and forcing you to find solutions “RIGHT NOW”. While others in normal IT Ops have time to test things, Event-IT things are often MacGyver jobs. Working on a remote unknown site with other people’s IT Infrastructure and take what you get, at the end nobody cares – it need to work. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Whoever works with Linux servers on the web knows it, logs filled with attempted accesses, bruteforcers or simply spambots. Fortunately, there are some sites that have specialized in collecting these “bad IPs” via honeypots or logging reports. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Just as a note to myself or anybody who is interested in it, feel free to use. Often you come across hrefs linking to ssh://user@whatever:22. By default, Windows does not know what to do with this protocol. If you go to select the standard protocol handler for it, you only get redirected to the MS Store, offering you some expensive terminal apps you actually do not want to use. I, for myself, have been using the Pro version of MobaXterm for many years. MobaXterm has shell integration, but I never got it running right or being selectable as a protocol handler, unfortunately. But this is why I made this little method to actually make it working. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Thanks to the Unitymedia Expansion in Bochum I have a Gigabit connection for quite some time now. Unfortunately the previous router had some problems with it. Also the function of the router was not according to what I would like to see for myself. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Probably you already read that Message and landed here because of this: This lobby is not joinable. Players in the lobby may have different NAT types than yours, which can limit network features. COD BLACKOUT is another Call of Duty with a “interesting” Network Code. Different than BF the COD Series relies on P2P Matchmaking instead of Dedicated Servers. So because now Everybody is “a Server” this can cause some Trouble if you are behind a more or less restricted Internet Connection. Specially Campus or Company connects share one broadband Line to many users. Unlike normal home users, you have to be more economic with port ranges here. But also some Home Routers use more restrictive types of NAT (Network Adresse Translation). ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. This is an updated posting from my older German Article. **I don’t want to give a rating of the Subsystem for Linux; for some, it is very useful; others may not be so happy about it, but let’s get straight to the point. The most pain I had was having my private key in the Subsystem and needing to re-authenticate every time by entering the key. I’m used to using the Keepass integrated (plugin) Agent, and that’s why my key has a password that’s too long to type. ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Translation This original post is written in german 🇩🇪, a rough Translation: I set up my own Freifunk hotspot: a TP-Link CPE210 v1.1, great value and unexpectedly wide range, covering half a three-story house even behind it. It runs as FF-BO-WAT-Bismarckplatz, offering free WiFi at Bismarckplatz. Coverage in Bochum is sparse; no nearby mesh partner yet. ...

After some days with the new Microsoft Surface 4 Pro I’m quite happy with it. One thing bugged me was the poorly SSD Performance. Microsoft use a Samsung M2 SSD with NVMe Protocol, actually a quite fast little thing. But a SSD Benchmark showed me unbelieveable bad performance at the Random Write and Threaded read: ...

Hey, just a heads-up that this content is based on an automatically imported version from our old CMS. If the formatting isn’t perfect, I’m sorry about that. Translation This original post is written in german 🇩🇪, a rough Translation: Black Ops 3 PC has performance issues, especially mouse input lag and micro stutter, even on high-end systems. Fixes: disable Dynamic Shadows, Subsurface Scattering, and Independent Transparency; set Low Shadow Map. For micro stutter, cap FPS slightly below monitor refresh (e.g., 58 FPS for 60 Hz) via config. ...

Translation This original post is written in german 🇩🇪, a rough Translation: Is KeePass insecure? With KeeFarce, contents of an unlocked KDBX can be exported in plain text without notice. My test on KeePass 2.30 exported everything. Locked DB is safe; KeeFarce can’t decrypt. Works on Win7/8/10, 32/64-bit. Advice: close DB quickly, use 2FA, auto-lock, disable unused features. ...
