I'm thinking of a "two stage procedure" that can be implemented well with /etc/rc.conf. Stupid idea, I know, but it should work, allthough you could make it more tidy: # First create /etc/ifconfig.conf if not already there if [ ! -f /etc/ifconfig.conf ]; then echo "#!/bin/sh" > /etc/ifconfig.conf ALIAS=0 while [ ${ALIAS} -lt 125 ]; do echo 'ifconfig_rl0_alias${ALIAS}="inet 80.252.2.`expr ${ALIAS} + 4` netmask 255.255.255.255" >> /etc/ifconfig.conf ALIAS=`expr ${ALIAS} + 1` done fi # Now source it into /etc/rc.conf . /etc/ifconfig.conf # Done. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
