| Issue |
I have 10 modems, whenever somebody dials in I want to assign a different ip address to it. How can I do this? |
| Solution |
#!/bin/sh
tty=$(/bin/basename `/bin/tty`)
blah=${tty%%?}
ttyno=${tty##${blah}}
if echo $tty | /bin/fgrep mdm >/dev/null 2>&1; then
exec /usr/ucb/pppd modem proxyarp $* quics:ppp${ttyno}
else
echo "You must be on a modem device to run pppd"
echo "(tty = $tty, ttyno = ${ttyno})"
exec sleep 5
fi
As you can see, we do a 'tty' to get the login terminal, then parse the output to get the number that we want. After this, we add it to the ppp string and look in our /etc/hosts file for the ip address. |
