Perhaps you guys can make this one better. Haven’t put a ton of thought into it:
C:\> (echo HTTP/1.0 200 OK & wmic process list full /format:htable) | nc -l -p 3000
Then visit http://127.0.0.1:3000
This could of course be used to generate a lot more HTML reports via wmic that are quick to save from the browser. The downside is that in its current state is that the page can only be visited once. Adding something like /every:5 just pollutes the web page with mostly duplicate output.
Assuming you already have netcat (nc.exe) on the system the command above will work fine, but it will only work once. After the browser recieves the data the connection has been used and the command is done. To do this multiple times you must wrap it in an infinite For loop.
C:\> for /L %i in (1, 0, 2) do (echo HTTP/1.0 200 OK & wmic process list full /format:htable) | nc -l -p 3000
This will count from 1 to 2 and count by 0, which will never happen (except for very large values of 0). We could use the wmic command to request this information from the remote machine and view it in our browser. This method will authenticate to the remote machine instead of allowing anyone to access the information.
C:\> wmic /node:joelaptop process list full /format:htable > joelaptopprocesses.html && start joelaptopprocesses.html
This will use your current credentials to authenticate to the remote machine, request the remote process in html format, save it to a file, and finally open the file in your default viewer (likely your browser). If you need to use separate credentials you can specify /user:myusername and /password:myP@assw0rd.
Hal, your turn, and I want to see this in nice HTML format. :)Hal throws up some jazz hands:
Wow. Tim seems a little grumpy. Maybe it's because he can make a simple web server on the command line but has no way to actually request data from it via the command line. Don't worry Little Tim, maybe someday...
Heck, maybe Tim's grumpy because of the dumb way he has to code infinite loops in CMD.EXE. This is a lot easier:
$ while :; do ps -ef | nc -l 3000; done
Frankly, most browsers will interpret this as "text/plain" by default and display the output correctly.
But the above loop got me thinking that we could actually stack multiple commands in sequence:
while :; do ps -ef | nc -l 3000 netstat -anp | nc -l 3000 df -h | nc -l 3000 ... done
Each connection will return the output of a different command until you eventually exhaust the list and start all over again with the first command.
OK, now let's deal with grumpy Tim's request for "nice HTML format". Nothing could be easier, my friends:
$ while :; do (echo '<pre>'; ps -ef; echo '</pre>') | nc -l 3000; done
Hey, it's accepted by every major browser I tested it with! And that's the way we do it downtown... (Hal drops the mic)
