AS I'm living in germany I've flatrate with T-DSL.
SME5.5 worked well so I've updated to 5.6.
INTERNET DIDN'T WORK!!!!
Found an error in a template after MANY hours sitting over the box...
Should you have problems:
File: /etc/e-smith/templates/var/service/pppoe/pppoe.pppd.conf/username
change:
user ( "$DialupUserAccount" )
to:
user ( "\"$DialupUserAccount\"" )
BTW: you can do so after your update/installation and BEFORE SME will reboot! ( change to console #2! and use vi! )
