Dear Maintainer, It seems that the sed expression that determines the interface in the ip-up script assumes that the configuration file specifies the interface as "iface xxx0", while the correct syntax is "iface = xxx0". This causes the ip-up script to basically never fire if the 'iface' option is used. The fix is simply to account for the = sign in the expression, such as: sed -n 's/^[[:blank:]]*\(iface[[:blank:]]\+=[[:blank:]]\+[[:alnum:]]\+\)[[:blank:]]*$/\1/p' /etc/inadyn.conf Cheers! Alessandro
