Homework and Emergencies Emergency UNIX and Linux Support Netcat ( nc -l ) as webserver Post 302987769 by Corona688 on Thursday 15th of December 2016 11:59:21 AM

This is going to be a royal pain to do in the shell. You're going to get stuck waiting on input from the web service while the web browser is stuck waiting on input for you. Named pipes are prone to this, even used one-way -- using a pair means almost guaranteed deadlock.

If you have Python or Perl, I'd look into writing it in that language instead. You would use a socket directly, avoiding the need for these deadlocks.

Another alternative, which I know you didn't want, would be the expect language. It can work pretty much the way you were expecting - run a program, check if it's got input, check if it's got output, decide what do do with it, move on.

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)

XDG-SETTINGS(1) 						xdg-settings Manual						   XDG-SETTINGS(1)

NAME
xdg-settings - get various settings from the desktop environment SYNOPSIS
xdg-settings {get | check | set} {property} [subproperty] [value] xdg-settings {--help | --list | --manual | --version} DESCRIPTION
xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop environment's libraries (which would use the settings natively). xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root. OPTIONS
--help Show command synopsis. --list List all properties xdg-settings knows about. --manual Show this manual page. --version Show the xdg-utils version information. PROPERTIES
When using xdg-settings to get, check or set a destkop setting, properties and possibly sub-properties are used to specify the setting to be changed. Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided in a sub-property. EXIT CODES
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned: 1 Error in command line syntax. 2 One of the files passed on the command line did not exist. 3 A required tool could not be found. 4 The action failed. EXAMPLES
Get the desktop file name of the current default web browser xdg-settings get default-web-browser Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current value (if only some of the underlying settings actually reflect that value) xdg-settings check default-web-browser firefox.desktop Set the default web browser to google-chrome.desktop xdg-settings set default-web-browser google-chrome.desktop Set the default mailto URL scheme handler to be evolution.desktop xdg-settings set default-url-scheme-handler mailto evolution.desktop AUTHOR
