Behold the power of |!
Posts related to networking, this is very broad. Stuff related to TCP, IPv6,… but also things like Apache HTTPd, Postfix,…
Hey Guys, Lately I’ve been thinking about replacing my ESXi setup I have at OVH with a SmartOS one. I got a cheap kimsufi server for one month to play around. As you know those do not have multiple IP’s/NIC’s. I wrote a little dirty how to on how to setup NAT in the globalContinue reading SmartOS with single IP and NAT
It’s been a while since I posted but I only recently started tinkering with things again in my free time. I travel a lot now for work so I spend some lonely nights in hotel rooms with no internet. I have time to play. Anyway, I wanted to host a repository for OmniOS because I’mContinue reading Running OmniOS/OpenIndiana under ESXi hosted at OVH
For work I was migrating an old undocumented reverse proxy configuration from 2.0 to 2.2. It contained some old perl scripts nobody understood and some strange bits here an there. Long story short I started from scratch. I ran into the usual problems like redirects and hyperlinks being broken if they use full self referencingContinue reading Reverse Proxy and Hyperlinks
I’ve been wanting to write about this for a bit. I usually VPN (to the gateway at home) for surfing when roaming. This also gives me access to my shellbox and with my ssh key. You can usually connect to port 443 (https) on most networks, even those that force you to use a socksContinue reading Tunneling over ICMP
Here is a short tutorial on how to setup a multi stage authentication with an Apache HTTPd 2.4 server. The first stage will do a 2-way SSL encryption, so both server and client will need to present a certificate. The second stage will be password authentication, the username has to match the username in theContinue reading multi stage authentication using Apache HTTPd 2.4
I previously mentioned rpmbuild. I wanted to write a little post on what it does and how useful it is. But I though it would be easier to just show you. So what is rpmbuild? It is a tool for building rpm packages based on a spec file. The resulting rpm should be close toContinue reading Apache HTTPd 2.4 on RPM based distributions
Here is a little trick to connect to a server that requires a SSL Client certificate when your client does not support it. To make it work your client must be able to use a proxy. We will use this proxy to rewrite certain servers to a reverse proxy that injects the client certificate. LetsContinue reading SSL Client certificate injection using reverse and forward proxies
Due to popular demand (I got 1 e-mail, but hey they’ve been gone for a few days). I’ve added some of the old Apache HTTPd 64-bit binaries to the download page under archive. Please use them with care. It is possible I’ll redo the compile tutorial at some point but I currently don’t have accessContinue reading Apache HTTPd 64-bit binaries
Some of you may have noticed, but most probably haven’t. All my important public facing services are now IPv6 ready! DNS (caveat only my primary ns server is IPv6 ready – including glue) HTTP(s) (This website and webmail are available over IPv6) SSH SSL VPN IMAP SMTP (This was my main motivation to move toContinue reading IPv6, Are you ready?
I recently came upon a IETF draft that was published a few weeks ago. 451 Unavailable For Legal Reasons This status code indicates that the server is subject to legal restrictions which prevent it servicing the request. Since such restrictions typically apply to all operators in a legal jurisdiction, the server in question may orContinue reading 451 Unavailable For Legal Reasons
