I haven't tried ktracing it (first I've heard of ktracing).  Here is the script:


$ cat dns_update.sh 
#!/bin/sh

user_id="something"
password="secret"

ip_addr=`netstat -rn | egrep ^0.0.0.0 | sed -e "s,.* ,,g" | \
        xargs /sbin/ifconfig | grep "inet.addr" | sed -e "s,.*addr:,," \
        -e "s, .*,,"`

now=`date`

lynx -source -auth=$user_id:$password \
        http://www.yi.org/bin/dyndns.fcgi?ipaddr=$ip_addr | \
        sed -e "s,^,$now: ," -e "s,<.*\?>,,g"


So yes, some variables are set, but this shouldn't affect lynx would it?

I don't know how/if fetch can be used in this instance.
