  1. Dropbear Public-Key Authentication

    Tue 07 August 2012
    By makefu

    ssh-copy-id does not work out of the box for dropbear. The issue is that dropbear may only have one authorizedKeys file while openssh handles this file for each user. To fix it symlink the root users authorizedKeys file to the dropbear one.

    openwrt>> ln -s /root/.ssh/authorized_keys /etc …

    Getting irssi running with utf8 support in a putty/tmux stack is madness. Here is what you have to do.

    add lines in .{ba,z}shrc:

    export LANG=en_US.utf8
    export LC_ALL=en_US.utf8
    

    add lines in .tmux.conf:

    set-option -g default-terminal "rxvt"
    set-window-option -g utf8 on …

  5. Getting Hama Nano DVB-T Stick to work

    I initially bought it because i wanted to play around with software defined radio on the cheap [1] but haven’t had the time. As this thingy is originally an DVB-T stick i wanted to try this out first. As it contains a fairly common RTL2832U chip, it shouldn’t …

    Daemonizing and autostarting a process is still a pain in the ass, so here are two scripts which can be placed under /etc/init.d and if you are lucky everything will work.

    I’m using a Sandisk Cruzer 8GB SDCZ36-008G-E11 (not B35) to deploy ISOs on the virtual CD-Rom drive (U3 Smart).

    write iso

    Some computers do better with a real cd-rom drive when botting a live system.

    Tue 07 February 2012
    By makefu

    I had the requirement to create a certificate with a subject Alternative Name (additional dns names for the same host). Again it turned out not to be that simple. A extra configuration has to be created and the SubjectAltName can be added in this config for the Signing Request.

    We …

    These snippets are in a ”worked for me” state. most of this stuff will break your system when executing.

    Assumptions:

    • /srv/http/euer.krebsco.de - served by lighttpd on public interface
    • /srv/http/priv - served on private interface (darknet)

    lighttpd seperate subdomain logging and awstats
