Actually, that is possible. I have AT&T myself, and They recently
sent me a letter asking me to reconfigure my dhcp client. Turns out
it came in the mail just hours before my machine went offline. I had
to unplug the modem for about a minute and reboot my machine. Even
then, I had to manually restart the dhcp client.
It's pretty ugly, but I have a quickie script that does that for me:
kick_dhcp.sh:
#!/bin/sh
/usr/bin/killall dhclient
/bin/sleep 1
/sbin/dhclient xl0
/bin/sleep 2
PING=`/sbin/ping -c 1 netnews.attbi.com | /usr/bin/grep " 0% packet
loss"`
if [ "$PING" ]; then
exit 0
else
/usr/bin/killall dhclient
/bin/sleep 1
/sbin/dhclient xl0
fi
I know there is probably a cleaner way to do this, for instance, I
don't think the dhclient process stays resident, but it does the job.
If the dhcp isn't negotiated, the ping fails and the restart is
retried. I also see a message on stderr that the lookup failed.
The drawback is that if the dhcp negotiation works, but
netnews.attbi.com is unavailable for other reasons, it will try to
restart dhcp even though it is fine.
