Homework and Emergencies Emergency UNIX and Linux Support Netcat ( nc -l ) as webserver Post 302987765 by chakrapani on Thursday 15th of December 2016 10:46:38 AM
Old 12-15-2016
I made a named pipe and seems very close to getting my solution of garbing HTTP headers, Also noticed my browser does not Always send all the header each time.
(Chrome Version 54.0.2840.99 even in incognito )

My workaround (not solution) have a named pipe to communicated with nc.

Code:
$ mkfifo  webout

and then have the while loop to feed netcat(nc)

Code:
while true; do { echo -e 'HTTP/1.0 200 OK\r\n'; cat webout;  } | nc -vl 8080 >webout; done

I am just playing around with named pipe, looking to find something in the lines of:

Code:
nc -l PORT <webin > 2&1>webout

and then loop out with tail kind of thing on webin and webout. Any experts on FIFO's please suggest.

Netcat with Authentication?

I'd like to do a data transfer without encryption but with a guarantee that my data comes from a legit source. I'm thinking something that uses a public key scheme to sign the data. Does anyone know of something like that? Thanks! -Pileofrogs (1 Reply)

NAME
smokeping_cgi - SmokePing webfrontend OVERVIEW
This script acts as a 'website' for your SmokePing monitoring operation. It presents the targets you are looking at in a tree structure and draws graphs as they are required by people looking at the pages. DESCRIPTION
To get smokeping_cgi going, you need a webserver which allows you to run CGI or better FastCGI scripts. The system must be setup so that the cgi process is allowed to write to the image caching area as defined in the config file. This script runs fine as a normal CGI, BUT it will appear to be very slow, because it does a lot of things when starting up. So if the script has to be started a fresh on every click, this is both slow and a tough thing for your webserver. I therefore strongly recommend using FastCGI. Please refer to the installation document for detailed setup instructions. SETUP
There is a sample htdocs directory in your smokeping installation root. Copy its content to the place where your webserver expects its files. There are also two sample cgi scripts showing how to launch the smokeping cgi in your website. The only difference is the file extension. Adjust the paths in the script and you should be ready to go.
