My mail forwarding recently stopped working unless my PC has a valid hostname. I am trying to get ppp(8) to set the hostname automatically... but it turning out to be a lot harder than I thought. I am trying to get it done in a ppp.linkup, EarthLink: shell /root/sethostfromip MYADDR !bg /usr/sbin/sendmail -q !bg su cjc -c /usr/local/bin/fetchmail The script 'sethostfromip' does a reverse-lookup of MYADDR and tries to set the hostname accordingly (yeah, a quick program would probably be better, but I'm lazy), if [ expr $1 : '[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*' > /dev/null 2>&1 ]; then IP=$1 else IP=`ifconfig tun0 | awk '/inet/ { print $2 }'` fi HOSTNAME=`nslookup $IP | awk '/^Name:/ { print $2 }'` hostname $HOSTNAME However, the nslookup keeps failing and neither the sendmail or fetchmail runs very reliably. Here the stderr output from the sethostfromip when I wake up the PPP connection right now, *** Can't find server name for address 207.217.126.81: Timed out *** Can't find server name for address 207.217.77.82: Timed out *** Default servers are not available Here is the ppp.log showing those actually being run, Jul 11 00:22:31 <daemon.info> dialin-client ppp[58]: tun0: Command: EarthLink: shell /root/sethostfromip MYADDR Jul 11 00:23:03 <daemon.info> dialin-client ppp[58]: tun0: Command: EarthLink: !bg /usr/sbin/sendmail -q Jul 11 00:23:03 <daemon.info> dialin-client ppp[58]: tun0: Command: EarthLink: !bg su cjc -c /usr/local/bin/fetchmail Others must be setting new hostname when they do a dialup, right? How do you do it? I'm suprised it's not an option built into ppp... Or is it and I have not managed to find it? -- Crist J.
