Forum OpenACS Q&A: Response to script to modify the hostname and address in nsd.tcl

Here is the code I use to retrieve the IP address of eth0 in nsd.tcl

set my_ip [exec "/sbin/ifconfig" "eth0" "|" "grep" "inet addr" "|" "awk" "{print $2}" "|" "sed" "-e" "s/.*://"] is probably a better choice for a dynamic IP so you don't have to restart aolserver when your IP changes. (I think that is how it works anyways)

I recommend setting ForceHostP to 0 in parameters/.tcl if you have a dynamic IP so the hostname setting won't affect you.
