[fpc-pascal] RE: Get Local IP using glib (eth0,eth1)

[Graeme Geldenhuys]

I have these two functions in my .bashrc file.  You only need to run
"ii" for the cool output.  Now back to the question -  If it is for
linux only, why not just use the /sbin/ifconfig output.  After all, it
is accurate and seem much easier than all those libc/library methods.
I pull the IPs and Interfaces available from the /sbin/ifconfig output
and works just fine.  If it was needed on windows, I am sure you could
to the same thing with the 'ipconfig' output.

My 2c worth!  :-)

------------ .bashrc ---------------------
function my_ip() # get IP adresses
{
    MY_IP=$(/sbin/ifconfig eth0 | awk '/inet/ { print $2 } ' | sed -e s/addr://)
    MY_ISP=$(/sbin/ifconfig ppp0 | awk '/P-t-P/ { print $3 } ' | sed
-e s/P-t-P://)
}

function ii()   # get current host related info
{
    echo -e "\nYou are logged on ${RED}$HOST"
    echo -e "\nAdditionnal information:$NC " ; uname -a
    echo -e "\n${RED}Users logged on:$NC " ; w -h
    echo -e "\n${RED}Current date :$NC " ; date
    echo -e "\n${RED}Machine stats :$NC " ; uptime
    echo -e "\n${RED}Memory stats :$NC " ; free
    my_ip 2>&- ;
    echo -e "\n${RED}Local IP Address :$NC" ; echo ${MY_IP:-"Not connected"}
    echo -e "\n${RED}ISP Address :$NC" ; echo ${MY_ISP:-"Not connected"}
    echo
}
