I can easily rewrite the shell magic, but its >worth asking if there is some command better suited. I wrote a command in C++ that interrogates the TCP/IP stack directly to obtain the IP address of any given interface. I wrote it some years ago, so it's only IPv4 at the moment; it will take a day or two to add IPv6 support. I can send you the source code if you want. Likewise to any other interested reader -- or I can post it here as a mail attachment, since it is quite tiny. -- Regards, Dave [RLU #314465] ====================================================================== dwn...@ntlworld.com (David W Noon) ======================================================================
