get lirc working

# apt-get install inputlirc lirc input-utils lirc-x

boot from network

pxe

dhcpd

tftpboot

kernel

nfs

hostname

debootstrap sid

rcS/S40networking

ifconfig lo up 127.0.0.1

exit

don’t want to shutdown network (because it’s needed for boot process)

now mount -a should work without any “mount is older than kernel” warning messages.

apt-get install x-window-system

xorgconfig

/dev/MAKEDEV (tty, std, input ..)

rungetty -> xinit -> script -> starts myth-frontend

remote control

useful stuff for dvb-s

to scan the astra 28 satellite and dump contents to a file from which to choose lines of stations we want:

scan -s 1 -t 1 /usr/share/doc/dvb-utils/examples/scan/dvb-s/Astra-28.2E > ~/scan.out

scan -s 0 -t 3 /usr/share/doc/dvb-utils/examples/scan/dvb-s/Astra-28.2E > ~/scan.out

-s : diseqc position (I have 0 for Astra 19 and 1 for Astra 28)
-t : 1 for TV, 2 for Radio, 3 for both …

in order to avoid trouble when debian is changing their keys again, that’s the procedure:

blancheneige:~# sudo gpg --keyserver pgpkeys.mit.edu --recv-key A70DAF536070D3A1
gpg: requesting key 6070D3A1 from hkp server pgpkeys.mit.edu
gpg: key 6070D3A1: public key "Debian Archive Automatic Signing Key (4.0/etch) ” imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1
blancheneige:~# gpg -a –export A70DAF536070D3A1| apt-key add -
OK
blancheneige:~#

21/11/2006 made the mythfrontend executable suid root (at least I hope that’s how you do it …)

mythtv@teevee:~$ sudo chmod u+s /usr/bin/mythfrontend
mythtv@teevee:~$ ls -l /usr/bin/mythfrontend
-rwsr-xr-x 1 root root 1381376 Nov 16 21:43 /usr/bin/mythfrontend
