Lightbulb Netcat ( nc -l ) as webserver

Dear Linux guru's

I am trying to create a webserver using nc (netcat only) on RHEL 7.2 running on bash shell.

now the easy thing is to get nc listing to a port and respond back

Code:
$ while true; do { echo -e 'HTTP/1.0 200 OK\r\n'; set; } | nc -l 7877; done

This when called from a browser: http://My-server:7877 I get my env variables. Works perfect !! Love it Smilie

Now when I try http://My-server:7877?asd=1&something=2&other=hello

I was hopping to get QUERY_STRING env variable with all the values sent via browser GET method ! . However the env variable is not set. There is not variable set with these values.


Versions:

Bash
GNU bash, version 4.2.46(1)-release (x86_64-redhat-linux-gnu)

nc
Ncat: Version 6.40 ( Ncat - Netcat for the 21st Century )

redhat
Red Hat Enterprise Linux Server release 7.2

Dont want to use anything other than nc. Cannot install any tool or webserver or binaries. Please dont suggest that

And thanks all for reading my question Smilie.

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
weborf.conf - configuration file for weborf daemon SYNOPSIS
/etc/weborf.conf DESCRIPTION
Weborf is a minimal webserver. Also has a limited support for webdav. Can be started as stand-alone or as SystemV daemon. This manual page documents Weborf's configuration file, used only when it is started as daemon. On debian systems, the script to run weborf as a daemon is located into /usr/share/docs/weborf and has to be manually copied into /etc/init.d Weborf is released under the GNU General Public License version 3. DESCRIPTION
Options are case sensitive. Immediately followed by the equal = sign, without any space between name and value. Lines beginning with # will be ignored and treated as comments. indexes By default weborf searches for index.html. Anyway it is possible to specify a different index file and also many index files. Name of the pages must be separated by a comma and between them there aren't spaces. basedir Default base directory used by the webserver. The default means that this will be used also when virtual hosts are enabled, if the requested host is unknown. Of course the user used for the webserver will need to have access to this directory. use-cgi Can be true or false. If false weborf will handle all files as normal files. Otherwise it will use the CGI protocol to execute some files. use-mime Can be true or false. If true weborf will send the Content-Type header to the clients. Turning it off will increase speed but might cause problems with some old clients. cgi List of extensions to consider as dynamic pages and binaries to execute them auth-bin Path of the binary that provides authentication to weborf auth-socket Path of the unix socket that weborf will use to connect to the authentication server cachedir Will set the path of the directory used for caching user Username of the user that will run the webserver. On debian this is usually www-data. virtual This directive is used to enable virtualhosts. One line is needed for each port. The format is: vir- tual#port#domain1=basedir1,domain2=basedir2 EXAMPLE
Example file can be found in /usr/share/doc/weborf/examples/weborf.conf SEE ALSO
