I have not yet finished reading all of the digests, so I do not know if
what I am posting below has been posted already.
I have seen this specific "bad referral" message numerous times. After
a number of e-mail messages, I finally got a response from someone in
the US Army who said that they were working on their DNS problems.
IIRC, this response was about a month ago. I wrote this quick shell
script, which I named malf.exec:
grep Malf /var/adm/messages | \
sort +8 -9 | \
awk -f malf.awk | \
more
And here is the malf.awk script:
titania.ctd.anl.gov% cat malf.awk
# awk script to process "Malformed response" lines in var/adm/messages
# Aug 31 13:27:26 titania.ctd.anl.gov named[5304]: Malformed response from [170.210.2.65].53 (out of data in final pass)
# CURRENTLY will not print single occurrences.
# 01Sep00 1006AM Barry Finkel
# 22Sep00 0130PM Print the correct record.
BEGIN {oldip="";count=0;old1="";old2="";old3="";}
{
newip = $9;
if (oldip==newip)
{
count++;
}
else
{
if (count>0)
{
print old1 " " old2 " " old3 " count=" count;
}
oldip = newip;
count=0;
print $0
}
old1 = $1;
old2 = $2;
old3 = $3;
}
titania.ctd.anl.gov%
This looks for all "Malformed response" messages in /var/adm/messages.
We cut a new messages file each Sunday, and whenever I run this script,
I always see multiple occurrences from each of the three army.mil name
servers. I currently have three messages from each of the three
name servers since yesterday; by the end of the week the number will
probably exceed 30 for each.
