V Debian Linuxe nainstalujeme:

apt-get install br2684ctl pppoe pppoeconf libatm1 linux-image-2.6.17-2-686

Je potrebne stiahnut z netu firmware modemu a nahrat ho do

Po restarte spusti pppoeconf riad sa pokynmi. Treba zadat login                                                                                                                      
a heslo co doslo z T-COM-u. Potom treba upravit

ti prida do /etc/network/interfaces dsl-provider a nas0.

V tomto momente by malo DSL pripojenie fungovat samo, ale v mojom pripade sa
odmietla automaticky nahadzovat default route. Preto som napisal skript
dsl-start, ktory skontroluje pripojenie a pokusi sa nejake veci sam opravit.

Aby nam fungovalo DNS, pouzivame tieto DNS servery:

------------%<------------
$ cat /etc/resolv.conf
nameserver 195.146.132.59
nameserver 195.146.128.60
------------%<------------

Automaticka kontrola pripojenia (pustane pod rootom):

--------------------------------%<--------------------------------
$ crontab -l
# m h  dom mon dow   command
*/5  * * * * /usr/local/bin/dsl-start        >> /var/log/dsl 2>&1
*/13 * * * * /usr/local/bin/dsl-start start  >> /var/log/dsl 2>&1
--------------------------------%<--------------------------------

Do /etc/sudoers pridat riadok, aby uzivatel mohol nahodit internet sam:

---------------------------%<---------------------------
$ visudo
tail -n 1 /etc/sudoers
milus   ALL = (ALL) NOPASSWD: /usr/local/bin/dsl-start *
---------------------------%<---------------------------

Dakujem za pomoc mojmu kamosovi Milanovi Tothovi <milan AT toth-online.com>,
ktory bol ochotny spisat prvotny navod a podla ktoreho som to nakonfiguroval
cez GPRS (na pocitaci vzdialenom odomna 450 km). A taktiez dakujem mojim
rodicom za trpezlivost pri pisani obludnych linuxovych prikazov do textovej
konzoly diktovanych cez telefon, ked to nefungovalo a nevedel som sa na ten
pocitac pripojit.
