Tuesday, 21 December 2010. Transport layer protocols for stealth and evil. Ever tested some of the more exotic transport protocols? Is interesting . multihoming means you can have several ips involved on each side of a connection (association in sctp speak) . so when you move from wired to wireless your ssh session still is fine. If you find a proper SCTP ssh, of course. Socat SCTP-LISTEN:8080,fork TCP-CONNECT:localhost:22. Nice, stealthy backdoor. Does not show in netstat(8). Can do more fun sctp-specif...

Monday, 6 February 2012. Dnstool - curses-based DNS zone administration. Get it while the bits are still hot! The Fine Manual is plain text and even has screenshots, perfect for the old-school lynx enthusiast ;). If your dns server supports RFC2136 dynamic updates, you might want to look at this. BIND9 does.

Use of words: Transport layer for stealth and evil, 2014 edition
http://useofwords.blogspot.com/2014/07/transport-layer-for-stealth-and-evil.html
Tuesday, 29 July 2014. Transport layer for stealth and evil, 2014 edition. A few years ago, I tested some obscure transport protocols. On Ubuntu 10.04 and whether you could find processes listening for them on your system. Answer was - it depends. Fast forward a few years, RHEL7 and CentOS 7 appears. Long-deprecated netstat is gone from the default install. So let's repeat the tests for weird backdoors. Ss(8) is the official replacement for netstat(8). So what does ss see? Ss -anp grep socat. Sets up a l...

Thursday, 26 April 2012. Deploying FreeRADIUS, you may want to use a Certificate Revocation List (CRL) to revoke access to users that has been issued a valid certificate at some point. How to actually do this isn't completely self-evident. Less so if you use multiple sub-CAs. FreeRADIUS basically uses OpenSSL's routines and options for this. And OpenSSL doesn't currently refresh CRLs in a running process, so after updating a CRL you need to restart the freeradius daemon (easily scripted). File Synchroniz...

Wednesday, 17 August 2011. Japansk er fleksibelt og komplisert. La oss ta et tilfeldig verb, taberu - å spise. For det første er ikke ordbok-formen av verbet infinitiv på japansk. Ordbokformen av verbet er "uformell ikke-fortid" - kan hende det skjer omtrent nå, kan hende en bare har vage planer om det en gang i fremtiden, men det er iallfall ikke ferdig med å skje. Watashi wa niku ga taberu.". Uttales "Niku ga tabemas".). Niku ga tabetai desu.". Niku ga tabete mimasu.". Niku ga tabete mitai desu.".

Use of words: Unbreaking the web with greasemonkey
http://useofwords.blogspot.com/2013/05/unbreaking-web-with-greasemonkey.html
Saturday, 4 May 2013. Unbreaking the web with greasemonkey. So, a certain MMO recently managed to turn off their wiki, upgrade their forums and in the process break almost all their links from anywhere. Even intra-forum links broke utterly. And the in-game big friendly Help button. I'd really not want to responsible for that debacle. Breaking seven years worth of web forum google searches and intralinking is utter insanity from a professional standpoint. View my complete profile. Reviewing the Kanji (漢字).

Friday, 14 May 2010. Fun hardware - first results. Testing the Fusion-io ioXtreme 80GB (/dev/fioa) vs Intel X25-M gen 2 160G (/dev/sda). The non-directio dd went cpu-limited for some reason, needs looking into. 792 MB/s read speed at 12% cpu use in the directio case looks a bit promising :).
