Description Pete Zaitcev 2002-09-23 18:42:21 EDT
Description of Problem:

ping sometimes prints:

WARNING: failed to install socket filter
: Protocol not available

Version-Release number of selected component (if applicable):

iputils-20020124-3

How Reproducible:

It does this in different circumstances, but the easiest way
to reproduce is to run two pings in two terminal windows.

Steps to Reproduce:
1. Run "ping -n -M dont -s 200 151.164.129.3" in one window.
2. Start "ping -n -M dont -s 200 151.164.129.3" in other window.
3. [Can interrupt both pings and retry if message does not appear]

Actual Results:

[zaitcev@niphredil zaitcev]$ !ping
ping -n -M dont -s 200 151.164.129.3

[zaitcev@niphredil zaitcev]$ 

Expected Results:

Same, but without the warning message.

Additional Information:
	
1. It seems that both pings continue to function despite the
warning, because sequence numbers look correct in both windows.

2. The warning message itself has an extra newline. Make sure
the root cause is fixed before you fix the message though :)

3. The example above was tested with Marcelo tree, 2.4.19.
Same story with 2.4.18-10 etc. Seems like a generic error.
Comment 1 Phil Knirsch 2002-10-04 11:03:26 EDT
Could you try that on a Red Hat Linux 8.0 machine? I just tried the exact same
thing on my machines here and it works without the warning.

Thanks,

Read ya, Phil

Seems to be fixed on RHL 8.0.
