See the comments at the front of the 1218579Sfennerprogram for a description of its use. 1318579Sfenner 1418579SfennerThis program uses raw ip sockets and must be run as root (or installed 1518579Sfennersetuid to root). 1618579Sfenner 1718579SfennerA couple of awk programs to massage the traceroute output are 1818579Sfennerincluded. "mean.awk" and "median.awk" compute the mean and median time 1918579Sfennerto each hop, respectively. I've found that something like 2018579Sfenner 2118579Sfenner traceroute -q 7 foo.somewhere >t 22100784Sfenner awk -f median.awk t | xgraph 2318579Sfenner 2418579Sfennercan give you a quick picture of the bad spots on a long path (median is 2518579Sfennerusually a better noise filter than mean). 2618579Sfenner 2718579SfennerProblems, bugs, questions, desirable enhancements, source code 2818579Sfennercontributions, etc., should be sent to the email address 2918579Sfenner"traceroute@ee.lbl.gov". 30
