| 9 | Traceroute is a system administrators utility to trace the route |
|---|
| 10 | ip packets from the current system take in getting to some |
|---|
| 11 | destination system. See the comments at the front of the |
|---|
| 12 | program for a description of its use. |
|---|
| 13 | |
|---|
| 14 | This program uses raw ip sockets and must be run as root (or installed |
|---|
| 15 | setuid to root). |
|---|
| 16 | |
|---|
| 17 | A couple of awk programs to massage the traceroute output are |
|---|
| 18 | included. "mean.awk" and "median.awk" compute the mean and median time |
|---|
| 19 | to each hop, respectively. I've found that something like |
|---|
| 20 | |
|---|
| 21 | traceroute -q 7 foo.somewhere >t |
|---|
| 22 | awk -f median.awk t | xgraph |
|---|
| 23 | |
|---|
| 24 | can give you a quick picture of the bad spots on a long path (median is |
|---|
| 25 | usually a better noise filter than mean). |
|---|
| 26 | |
|---|
| 27 | Problems, bugs, questions, desirable enhancements, source code |
|---|
| 28 | contributions, etc., should be sent to the email address |
|---|
| 29 | "traceroute@ee.lbl.gov". |
