tcrules question
Hi,
I am confused about the tcrules syntax. When I try to shape a web server
running on fw with this line:
4 fw 0.0.0.0/0 tcp - 80
it works
but the "80" must be in CLIENT PORT, my logic says it should be in the
"PORT" column (doesn''t work there)
am I missing something or are the columns labeled wrong?
thx

shorewall friendly way of limiting ssh brute force attacks?
I was wondering if anyone had implemented rules like this in shorewall:
http://blog.andrew.net.au/tech
I see tons of brute force attempts on the machines I administer, and I like
the idea of limiting them without the need for extra daemons scanning for
attacks.
Thanks,
Dale

IPP2P broken?
Hi,
I tried shorewall 2.2.0-rc4 and 2.2.0-rc5 on 3 different machines (just to be sure it''s not pebkac). The IPP2P support is broken, line like:
DROP loc net ipp2p
generates:
iptables -A loc2net -j DROP
that''s _wrong_ :)
i have tried playing with debug to no avail, and I''m not that good at bashing...

Snort and Shorewall
Hello
I am looking for a way to have snort to dynamically update my shorewall config.
I have seen software out there but I would like to see if anyone had tried this
first.
Aslo I would like to know if there is a way clear the Netfilter tables when I do
a shorewall restart. The reason being is that when I make a change to my
firewall setting I want all connections to have to re-establish

OL8 (RHEL8), ssh-rsa turned off using update-crypto-policies, receiving an openssh error that I don't seem to be able to override in my personal .ssh/config file
The crypto policies are system-wide to disallow any software (using system crypto) from using unsafe/weak/unwanted algorithm, which is exactly what you are trying to do.
You?ll need to allow that system-wide by default, unfortunately. Luckily you can then disallow ssh-rsa in ssh-config by default and only enable it for a few hosts.
The correct solution is to throw whatever requires it to the

access deny host (ip) to access the Internet
I''m using shorewall 2.0.x at home as an Internet gateway for family.
However my brother always plays online games overnight, so my parents
asked whether I can do something on the gateway to control the time of
accessing the Internet.
I planned to put a script on crontab to schedule which it will execute
say at 12:00 night daily, the script will execute a command will deny

Dropping established connections
Hello,
I have searched the list but couldn''t find the right answer. I want to
drop an established DNAT connection but could not manage it yet.
Someone earlier said to bring down the public interfaces, stop
shorewall, bring up the public interface and then start shorewall again
but this won''t work.
I also saw a message from Tom that someone then should unload all

OL8 (RHEL8), ssh-rsa turned off using update-crypto-policies, receiving an openssh error that I don't seem to be able to override in my personal .ssh/config file
Lol! Our Security team sent out new policies that dictated turning off
ssh-rsa, so *we did. turns out our Security Team doesn't necessarily
follow their own dictates, so here we are. Our Linux team says that the
correct way to turn off ssh-rsa is via the crypto policies, not via direct
manipulation of the /etc/ssh/ssh_config, and I guess that's probably the
absolute best way to do so,

Solution to differential equation
Hello,
I am trying to find the analytical solution to this differential equation
dR/dt = k1*(R^k2)*(1-(R/Rmax)); R(0) = Ro
k1 and k2 are parameters that need to fitted, while Ro and Rmax are the
baseline and max value (which can be fitted or fixed). The response (R)
increases
initially at an exponential rate governed by the rate constants k1 and k2.
Response has a S-shaped curve as a function

Why still no PKCS#11 ECC key support in OpenSSH ?
PKCS#11 support for ECC should have been integrated years ago. Let's not complicate it now, just integrate the existing patches so that people stuck with EC keys at least can use them somehow...

file name starting with [0-9]* not synchronized (!?)
Hi,
I'm trying to backup a remote directory. Although the remote directory
hasn't been changed after rsync's run, I realize that the supposed
synchronization missed some files. Does it have to do with rsync or I
miss something ?
Thanks very much,
Mihai.

paired samples, matching rows, merge()
Hi everyone!
I'm matching two samples to create one sample that have
pairs of observations equal for the k1 variable. Merge()
doesn't work because I dont't want to recycle the values.
x <- data.frame(k1=c(1,1,2,3,3,5),
k2=c(20,21,22,23,24,25))
x
y <- data.frame(k1=c(1,1,2,2,3,4,5,5),
k2=c(10,11,12,13,14,15,16,17))
y
merge(x,y,by="k1")

questions about nls
Dear R users,
I am new in R and I want to use the nls package to analyze some
experimental data. The data is in the attached file "data". It is the
response "Sav" measured at different "C0". Basically, the "C0" is a
function of C1, K2, and r, and the "Sav" is a function of C0, C1, K2,
and r. The math equations are shown in the attached

Readline - wait for user input
Hi,
I've seen various posts on this question, but still can't get the code
right.
If I run the following code one line at a time, it works fine. If I run
it together as a block, however, it doesn't wait for the input and gives
an error.
There must be a way to have are pause/wait for an answer, but I can't
seem to find it. Thanks! J
