How to compile python2.5 on SCO_SV

  • You must have PTH installed, and maybe other libs.
  • This was tested on SCO_SV os507 3.2 5.0.7 i386

If you have UDK, run:

$ CFLAGS='-I/usr/local/include -belf' LDFLAGS='-L/usr/local/lib' \
  ./configure --with-threads --with-pth --disable-shared --disable-ipv6
  • Add /usr/local/include to BASECFLAGS in Makefile (autocrap sucks).
  • Patch Modules/ctypes/_ctypes_test.c by putting an #ifdef HAVE_LONG_LONG around functions that use PY_LONG_LONG (hints: lines 384 and 318).
  • Patch Objects/longobject.c and on line 817 put the IS_LITTLE_ENDIAN macro before the #ifdef HAVE_LONG_LONG block, and put _PyLong_FromSsize_t and _PyLong_FromSize_t after the HAVE_LONG_LONG block.

If you have GCC, run:

$ CFLAGS='-I/usr/local/include' LDFLAGS='-L/usr/local/lib'            \
  ./configure --with-threads --with-pth --disable-shared --disable-ipv6

Either with UDK or GCC:

  • Edit pyconfig.h and comment out the socklen_t define
  • Edit Modules/socketmodule.c and on line 226 add || defined(SCO5) in order to define INET_ADDRSTRLEN.
  • Run make (or gmake if you wish)
  • You will be left without _curses.so, _curses_panel.so, _locale.so and readline.so if using GCC and also pyexpat, elementtree and sha512 if using UDK.

When Sysadmins Ruled the Earth

Novel logo

A really, really, really NERD novel by Cory Doctorow that tells about a bunch of sysadmins that strive to keep the good ol’ Net online after a catastrophic event that brought the entire world to its knees. They fight with scarce power and food supplies and communicate over the Usenet… using the good old alt. hierarchy.

Vote: 10+ for the geekiest thing I’ve ever read. It’s really worth the hour needed to read it completely. Enjoy it

How to Backup with Time Machine on a Network Share

Ingredients: Debian, Netatalk, Avahi, some trickery.

Step 1: Recompile Netatalk with SSL Support

Recompile Netatalk with SSL Support.

You can safely ignore the “.passwd” stuff, because afpd uses PAM for user authentication.

Hint: Disable the atalk protocol handlers in /etc/default/netatalk for a faster startup:

# Set which daemons to run (papd is dependent upon atalkd):
ATALKD_RUN=no        # appletalk protocol
PAPD_RUN=no          # printer sharing daemon (printers are soooo '90s)
CNID_METAD_RUN=yes   # don't remember but is needed, rtfm!
AFPD_RUN=yes         # you will always need this
TIMELORD_RUN=no      # my time lord's name is <a href="http://openntpd.org">openntpd</a>
A2BOOT_RUN=no        # boot? nah! :P

Step 2: Create a share for time machine backup data, by adding e.g.

# path         name           perms     charset
/some/where/tm "Time Machine" allow:vjt volcharset:"UTF8"

into /etc/netatalk/AppleVolumes.default.

Step 3: Let the AFPD server show up in finder

Download the avahi service file, put it into /etc/avahi/services and reload avahi with /etc/init.d/avahi-daemon reload (sorry, original links are broken).

Step 4: Set Up Time Machine Backup

You need two files on your afp network share: .com.apple.timemachine.supported and a dot-file named with your en0 MAC address. To create it, the easier way is to attach an USB/Firewire disk, rename it with the name of the intended network share (specified into the AppleVolumes file) and enable time machine on it.

Then, copy over the .00… file on the external disk into your home dir, eject the disk, mount the network share from the finder and copy the file there.

Finally, touch .com.apple.timemachine.supported onto the network share, and re-open time machine preferences: the size of your backup volume should be equal to the network share size :).
