See the comments at the front of the 121590Srgrimesprogram for a description of its use. 131590Srgrimes 141590SrgrimesThis program uses raw ip sockets and must be run as root (or installed 151590Srgrimessetuid to root). 161590Srgrimes 171590SrgrimesA couple of awk programs to massage the traceroute output are 181590Srgrimesincluded. "mean.awk" and "median.awk" compute the mean and median time 191590Srgrimesto each hop, respectively. I've found that something like 201590Srgrimes 211590Srgrimes traceroute -q 7 foo.somewhere >t 221590Srgrimes awk -f median.awk t | xgraph 231590Srgrimes 241590Srgrimescan give you a quick picture of the bad spots on a long path (median is 251590Srgrimesusually a better noise filter than mean). 261590Srgrimes 271590SrgrimesProblems, bugs, questions, desirable enhancements, source code 281590Srgrimescontributions, etc., should be sent to the email address 291590Srgrimes"traceroute@ee.lbl.gov". 301590Srgrimes
