hostname -i yields my internal address, presumably because that is how
/etc/hosts knows my host name ip by the hostname.
The following works with ifconfig:
cat <<EOF >/usr/bin/get_inet_addr
#!/bin/sh
set -- `/sbin/ifconfig $1 | grep "inet addr"`
IFS=':'
set -- $2
echo $2
EOF
chmod +x get_inet_addr
get_inet_addr eth0
but I don't have an Eigerstein box up so I can't test one to work with
iproute2. I imagine it would use "ip addr show eth0", something like:
cat <<EOF >/usr/bin/get_inet_addr
#!/bin/sh
set -- `/sbin/ip addr show $1 | grep "inet"`
IFS='/'
set -- $2
echo $1
EOF
chmod +x get_inet_addr
get_inet_addr eth0
but this could be buggy. :)

For a web page, having all this information does seem more useful than
having just one bit of it.
