A dirty hack to achieve desired behavior. none

Description Scott Schmit 2011-03-26 18:17:52 UTC 
Description of problem:
There's been an announcement that net-tools has been deprecated in favor of iproute. Specifically, ss is to replace netstat.

However, when using ss to look at UDP sockets, I'm pretty sure the interface is wrong.

Version-Release number of selected component (if applicable):
iproute-2.6.35-6.fc14.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Perform "ss -u"
2. Compare to "netstat -u"
3. Perform "ss -ul"
4. Compare to "netstat -ul"
5. Perform "ss -ua"
6. Compare to "netstat -ua"

Actual results (if no UDP communication active):
1 & 2 & 3 match
4 & 5 & 6 match

Expected results (if no UDP communication active):
1 & 2 match
3 & 4 & 5 & 6 match

Additional info:
In other words, for netstat, -ua is -u + -ul
For ss, -ua appears to be -u + -ul + ?????

A dirty hack to achieve desired behavior.

Proposed upstream.

Still seen in iproute-2.6.39-3.fc16.x86_64

(Just avoiding the "Fedora 14 is reaching EOL" sweep.)
