1. 'Lm-Sensors: Hardware Monitoring With the W83627ehf Module'

    Sun 30 August 2009

    I have two systems that use the w83627ehf driver for hardware monitoring. However, if this driver is installed with a regular modprobe like:

    modprobe w83627ehf
    

    The result will be:

    FATAL: Error inserting w83627ehf
    (/lib/modules/2.6.28-1-amd64/kernel/drivers/hwmon/w83627ehf.ko): No such
    device
    

    I had this issue with the following mainboards:

    Asus P5Q-EM DO (Core 2 duo) Asus: P6T deluxe (Core 7i)

    The solution is simple, as I found after googling for some time:

    modprobe w83627ehf force_id=0x8860
    

    The result:

  2. Using Ncat to Provide SSL-support to Non-Ssl Capable Software

    Fri 21 August 2009

    Sometimes, people are using software that does not support encrypted connections using SSL. To provide SSL-support to such a client, ncat can be used. Ncat is part of nmap, the famous port-scanner.

    The main principle is that the non-ssl capable software does not connect to the SSL-based service, but to the local host. Ncat will be listening on the localhost and will setup an SSL-connection with the SSL-based service on behalf of the non-ssl capable software.

    This simple command allows an application to browse to port 80, and perform regular HTTP-request, while in fact, they are encapsulated within a SSL- connection:

    ncat -l 80 -c "ncat (ip-address) (port) --ssl"

    The -l option specifies the local port on which the SSL-tunnel will be listening. The ip-address and port refer to the SSL-based service.

    So if the client connects to 127.0.0.1 on port 80 it will actually connect through the SSL-tunnel to the external service.

    Often stunnel is used for this job but this software craps out on debian Etch with some error like:

    SSL routines:SSL3_GET_RECORD:bad decompression

    But ncat is an excellent alternative.
