From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Description of problem: I have two boxes here running rh 7.3 with the same traceroute package, same kernel...etc etc. The problem is that one box uses 32769:65535 udp port (as source ports) range when I do a traceroute and the other box use 1024:65535 udp range (as source ports). I didn't any other parameter of the box. Why the second box is using a differente port range? md5sum signatures are the same. The second box forces me to change my firewall!! :( Version-Release number of selected component (if applicable): traceroute-1.4a12-2 How reproducible: Always Steps to Reproduce: 1. run traceroute and tcpdump in the boxes 2. compare the results of tcpdump Actual Results: Second box must do traceroutes to internet but it is not able to do that because the firewall rules. Traceroute is using incorrect source ports Expected Results: Traceroute must use 32769:65535 udp ports Additional info:
Try to use traceroute with -p to specify the port range. It seems that sth else is listening on specific UDP ports so the range is changed.
