Install Wheezy using Netboot or CD on T2000 (or I guess any Sparc V9) Install sipp from http://iweb.dl.sourceforge.net/project/sipp/sipp/3.3/sipp-3.3.tar.gz
apt-get install libpcap-dev (and openssl obviously and perhaps a few other like ncurses autoreconf -inf ./configure --with-pcap--with-openssl make make install Then start with gdb gdb ./sipp run # gdb ./sipp GNU gdb (GDB) 7.4.1-debian Copyright (C) 2012 Free Software Foundation, Inc.
