A little outdated in that many Linux distributions no longer come with
'netstat' by default - you now use the 'ss' command. You may be able
to
obtain netstat by installing some form of network-legacy package, of course.
As for blocking IPs that access you too frequently, there's 'fail2ban'
which can do this more flexibly and configurably.
As for #3 I'm not sure, but I'd be surprised if there wasn't some tool for
that as well.

Hi,
From a quick skim, these seem poorly written. They might do what's
required some of the time but are no better than a quickly knocked-up
attempt I'd do myself.
Use the awk command to display only the data in column
5, and then
display the information of the IP address in column 1
...
netstat -atn | awk '{print $5}' | awk
'{print $1}' | sort -nr | uniq -c
The second awk does nothing, even though it's documented.
find $dir -type f|xargs md5sum > /tmp/md5_a.txt
ssh $b_ip "find $dir -type f|xargs md5sum > /tmp/md5_b.txt"
scp $b_ip:/tmp/md5_b.txt /tmp
#Compare file names as traversal objects one by one
for f in `awk '{print 2} /tmp/md5_a.txt'`
Looks like that ‘print 2’ should be $2. Presumably it was corrupted on
its long journey of cut-and-pastes and renderings. The '' quoting is
also adrift as what's there lumps the AWK with the input's path.
if grep -qw "$f" /tmp/md5_b.txt
This checks if an A file is present in B. There is nothing to spot new
files in B not in A.
then
md5_a=`grep -w "$f" /tmp/md5_a.txt|awk '{print 1}'`
md5_b=`grep -w "$f" /tmp/md5_b.txt|awk '{print 1}'`
Both 1 should be $1 to get the MD5 for the path. And grep's -w isn't
the right way to pick out the line.
$ md5sum * | grep -w foo
d41d8cd98f00b204e9800998ecf8427e foo
d41d8cd98f00b204e9800998ecf8427e foo extra
$
I didn't read further.

I would be cautious with that sort of accusation. I've seen Ken here's traffic
on TUHS and COFF for a little bit now and at least myself have never seen him try and pass
off a false identity. I've seen email replies reach TUHS from Ken Thompson himself,
there's nothing I've seen in this Ken's messaging that appears to present a
facsimile of Ken T. or anyone else. Of course, if such misdirection is happening and can
be proven, probably best to warn Warren directly on that sort of thing.
That all said, yeah, I don't see this sort of email being too relevant to COFF.
I'm no moderator so I won't claim to have authority on anything, but I for one
tend to ignore just about anything Linux-oriented or specific in this list and TUHS.

P.S. Sorry to backseat mod at all, I just have seen this sort of thing before, I
don't think anyone involved has bad intentions, communicating over the internet is
hard.

I believe (and I think I have seen more than once) that on multicore
computer all parts of the pipe will be ran on their own core, if
possible. Thus a script with pipes would give about the simplest way
to modernize this "old school" kind of processing.

Hi Larry,
I can program in Python but I have a huge aversion to
a programming
language that doesn't include printf in the base language.
Python has Perl's sprintf() but as the ‘fmt % values’ operator rather
than a function. So it isn't just available for printing but general
string formatting.

You can relegate any Linux grumbles from me to the cheap seats. It's my daily driver
as it is for many folks, I certainly wouldn't steer discussion away, my opinions on
the matter are informed by my own biases after all...
Can't complain too much though, I keep coming back to Linux for the hardware
support...due to the nature of the BSD licensing there are probably a lot more BSDish
drivers floating around out there than we see, but they're only in use by a select
few.

Heh.
I own fsf.net. That, once upon a time, was the Flathead Software Foundry. I, obviously,
registered that domain pretty early in the grand scheme of things.
If the actual Free Software Foundation wants it (they've never asked), it's
theirs for the cost of registration. Everyone else can just eff right off. I turn down
offers for it occasionally, but none of them have come close to what I consider a
reasonable cost for my effort for migrating off of it would be.

Hi,
I would be cautious with that sort of accusation.
KenUnix replied but it didn't make it to the list.
He's asked me to forward it on.
To put everybody at ease my "handle" KenUnix has been in use by me
for many years.
It was never intended to be used to disguise me as someone else
It dates back to Ken (me) and using Unix for many years. I E. KenUnix.
Ken
