DELETE

a
route
CHANGE
Modifies an existing route
Specifies the destination host.
Specifies that the next parameter is the 'netmask'
Specifies a subnet mask value to be associated
with this route entry. If not specified, it defaults
to
255.255.255.255.
gateway
Specifies gateway.
METRIC
Specifies that the next paramenter 'metric' is the
cost for this destination
All symbolic names used for destination are looked up in the network
database
file NETWORKS. The symbolic names for gateway are looked up in the
host name
database file HOSTS.
If the command is PRINT or DELETE, wildcards may be used for the
destination
and gateway, or the gateway argument may be omitted.
Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) !=
DEST.

TELNET [host [port]]
Connect to remote utility at host on port.
Host can be either an IP-address or a name based address.
Port is default 23.
Within telnet the followng commands might be available:
close
close current connection
display
display operating parameters
open
connect to a site (host port)
quit
exit telnet
set
set options (type 'set ?' for a list)
status
print status information
unset
unset options (type 'unset ?' for a list)
?/help
print help information
Comments:
The port command line parameter is not documented in either UNIX,
LINUX nor
Windows (to my knowledge). I guess this is because the telnet client
was
designed with the sole purpose of connecting to a telnet server. But
the
telnet client can be used to almost everything where a simple
diagnostics
is needed.
I have seen some wild acrobattic being performed on UNIX to change
the telnet
client from using port 23 to use any other port. I have tried on an
old
LINUX where it seams to work just fine putting the port number on
the
command line.
Connect to remote webserver on port 80:
Let's try the web server at carl-fh.net.
Start a DOS command prompt
From the command prompt type
telnet
Turn on localecho so you can see what you are doing (on some Windows
OS).
set local_echo
Connect to remote server.
open carl-fh.net 80
Press Enter on a blank line and type
GET / HTTP/1.1
host: carl-fh.net
Press Enter twice
The above command will ask for the start page in the documant root
using
protocol HTTP/1.1
The command should result in a whole lot of data comming from the
remote
server. You will get to see things that only your browser normally
see.
Alternative:
Another very good alternative is the PuTTYtel available at:
http://www.chiark.greenend.org.uk/~sgtatham/putty/
