This script can do # nice things such as kick off "sendmail -q", "popclient my.isp" and # "slurp -d news". It can be passed MYADDR, HISADDR and INTERFACE # as arguments too - useful for informing a DNS of your assigned IP. # # You may also want some sound effects.... # pmdemand: !bg /etc/ppp/ppp.etherup.pmdemand ! sh -c "cat /etc/ppp/linkup.au >/dev/audio" Greg -- When replying to this message, please copy the original recipients.
