3.3 Customization

This section covers the minimum customization needed to run ttylinux. More system configuration and customization can be done; see the system guide, section 5, below for information.

The configuration files and options described in this section are present in a ttylinux system installed from the bootable CD-ROM. Following the installation instructions above, the file system is in mnt/newroot, that is the example starting point for the following customization descriptions.

/etc/fstab

/etc/fstab needs to have the correct device for the root directory, the manually installed ttylinux /etc/fstab still specifies a RAM disk device for the root directory. Change the RAM disk device, /dev/ram0, to be the disk partition device in which the ttylinux root file system was installed. In the above example /dev/hda8 was used, so for that example the root directory in /etc/fstab would be specified as:

/dev/hda8     /     ext2     defaults     0 0

Boot Loader

The boot loader needs to be aware of the ttylinux kernel and root file system device. Following the installation instructions above, the LILO configuration file /etc/lilo.conf would include the following. Note the initrd specifier is removed and the root specifier is changed to /dev/hda8.

image = /boot/ttylinux-vmlinuz
	label = ttylinux
	root  = /dev/hda8
	read-only

Keyboard Map and Timezone

To use the current keyboard map and timezone from the Linux computer being used to install ttylinux, use the following commands.

	rm mnt/newroot/etc/localtime
	cat /etc/localtime > mnt/newroot/etc/localtime
	mnt/newroot/bin/dumpkmap > mnt/newroot/etc/i18n/kmap

Dial-up Network Information

[The ttylinux PPP and ISDN structure is being re-organized.]

To set up the dial information for an Internet provider, you need to know the following:

the device your modem is connected to, i.e. /dev/ttyS1
the init string for your modem, i.e. ATZ
the speed your modem can talk to the computer, i.e. 115200
the phone number of your ISP, i.e. 1-800-LETMEIN
your user name at the ISP, i.e. joeuser
your password at the ISP, i.e. joepass

The above is for dialup using a modem. If you want to use ISDN dialup, you need to know the following:

the phone number of your ISP, i.e. 1-800-12345678
your user name at the ISP, i.e. joeuser
your password at the ISP, i.e. joepass
the phone number you want to use for dialing out
whether you want to use automatic or manual dialing

Edit the file mnt/newroot/etc/ttyisp.conf and make the appropriate changes. ttylinux works only with providers that launch a PPP session immediately after dialup, which should be true for almost all providers; if a different procedure is needed to login, your Internet connection will not work with ttylinux. The ttylinux approach will work with almost all providers in Germany. [The creator and original maintainer of ttylinux is Pascal Schmidt who lives in Germany.]

For ttylinux to use ISDN, you need to have USE_ISDN=yes in /etc/ttyisp.conf, the default is not to use ISDN. Also needed is a kernel with ISDN support and hardware support for your ISDN hardware. If you need kernel modules to run your ISDN hardware, you will also need to add those and a suitable /etc/modules.conf to the ttylinux file system.
