write a shell script to send email
i have a dailed-up machine (FC2) serving as Internet gw and Web proxying, remotely operated at another town. through, firewall setting, i have configured in such a way that, the machine only accept ssh from my own static ip gateway. but, the trouble is that, everytime the machine reboots. network service is restarting, firewall rule is loading, then, i have to call them and ask the office boy to get me the new dailed ip. pretty stupid, huh?. can i have a script, once the ip (internet gw ip, i mean) is changed, then, it will straight email to my account?? could it be possible??? give me a pointer to look into it. thanks...
