good
were the most commonly used an extremely
effective command line tools used for
port scanning and service and numeration
to see the various uses %uh in maps can
take in map into the command line
performer TCP port scan a single IP
address type in Napa then followed by
the IP address that you want to scan
I'm
and network or back but the ports that
are currently open on that system
to perform a scan on a network range by
entering the network address
and then specify the range size by a
slash
in the number of network address bits in
this case we're going to slash twenty
for Class C address range and then it
will begin to return all the ports that
are open on each of the systems within
that range
additionally can also perform a scan on
its crucial series addresses by using
dash so in this case will just do the
last 128 addresses
i doing 128 dash 255
to scan for particular TCP port you can
by those ports with a dash p I'm
followed by the port sichuan a scam so
in this case will do 21 and 23
and that will only skin those ports in
return the results
you can also scan for Ranger def reports
by doing dash P&N if we say wanna see in
the first hundred ports
which new 13 100
you can use a TCP axe can't determine if
any ports are filtered by a fire what
you can do this by doing a gash lower
case
s uppercase day
and then the address that your skin
and then
results showing what ports if any are
filtered you can also scan for you DP
services with the unique P skin with
lower case
s upper case you now because you need
fees in connection oriented this can
take significantly longer than 80 CT
scan to perform
so go ahead and cancel this one out
but if you wanna look for particular EDP
services you can also perform
a unique piece can on particular you the
key ports
so using the same command at this time
dash p and in the u.p port Inglis
canceled in 53 for DNS
and then return
on that by default in matthews's since
cancer happenstance
but depending on the security settings
up your target system she may have more
success with other TCP
black skins to include for connections
cans no scams
