I have try a c++ program using curlpp libraries in my VM, my intention is when i execute the program, i can get a file via tftp.
I tested this program on the VM , this program managed to get a file from another VM.
However when i run this program in beaglebone yocto , it prompt following error:
Protocol "tftp" not supported or disabled in libcurl
FYI,the beaglebone can the ping and greb file from VM using busybox tftp.
I get the curlpp recipes from https://github.com/openembedded/meta-openembedded/blob/master/meta-networking/recipes-support/curlpp/curlpp_0.8.1.bb. Am i missing anything on this?
Add PACKAGECONFIG_append_pn-curl = " tftp" in local.conf
Till solaris 10, below were the steps I followed to create an inetd service which worked fine for me, below are steps:
Open /etc/inet/inetd.conf file and add my application binary with all required arguments as line below:
myApp_5000 stream tcp nowait root /home/jack/myApp/bin/myApp myApp -h -P /home/jack/myApp/bin
Open /etc/inet/services file and add a entry there also as below:
myApp_5000 5000/tcp
Finally I used to execute the below command:
inetconv -f
This will automatically create my service and everythings works fine till Solaris 10.
But now in Solaris 11, when I perform the same exact steps first I get below error message when I execute command "inetconv -f":
The manifest being imported is from a standard location and should be imported with the command : svcadm restart svc:/system/manifest-import
Secondly, my service gets created but does not works, as it remains in maintenance state always, see below:
svcs | grep myApp
maintenance 12:35:03 svc:/network/myApp_5000/tcp:default
I tried disabling and enabling the service but didn't helped.
Is there anything changed in Solaris 11 with respect to this, or am I doing it in the wrong way.
OS info:
uname -a
SunOS myhost 5.11 11.3 i86pc i386 i86pc
Do an:
ls -ltr /var/svc/log/|tail
look inside the relevant log file for your service, and see if there are any clues...
I installed snort on Ubuntu 14.04 but am having issues seeing the alerts. I also want it to log the alerts to a GUI but am having issues also with MySQL database. Please guide.
You can test your installation running snort -v. Make sure you run snort as root user or else you will get an error as shown below.
Running in packet dump mode
--== Initializing Snort ==--
Initializing Output Plugins!
ERROR: Failed to lookup interface: no suitable device found. Please specify one with -i switch
Fatal Error, Quitting..
If snort -v is working then try running the basic IDS mode using
snort -d -l ./log -c snort.conf
where log is the directory where you want to store the log and alert files. snort.conf is the name of your snort configuration file. It should contain the your snort rules.
If you don’t specify an
output directory for the program, it will default to /var/log/snort
Here is the manual. https://www.snort.org/documents/snort-users-manual
Python's http.server (or SimpleHTTPServer for Python 2) is a great way of serve the contents of the current directory from the command line:
python -m http.server
However, as far as web servers go, it's very slooooow...
It behaves as though it's single threaded, and occasionally causes timeout errors when loading JavaScript AMD modules using RequireJS. It can take five to ten seconds to load a simple page with no images.
What's a faster alternative that is just as convenient?
http-server for node.js is very convenient, and is a lot faster than Python's SimpleHTTPServer. This is primarily because it uses asynchronous IO for concurrent handling of requests, instead of serialising requests.
Installation
Install node.js if you haven't already. Then use the node package manager (npm) to install the package, using the -g option to install globally. If you're on Windows you'll need a prompt with administrator permissions, and on Linux/OSX you'll want to sudo the command:
npm install http-server -g
This will download any required dependencies and install http-server.
Use
Now, from any directory, you can type:
http-server [path] [options]
Path is optional, defaulting to ./public if it exists, otherwise ./.
Options are [defaults]:
-p The port number to listen on [8080]
-a The host address to bind to [localhost]
-i Display directory index pages [True]
-s or --silent Silent mode won't log to the console
-h or --help Displays help message and exits
So to serve the current directory on port 8000, type:
http-server -p 8000
I recommend: Twisted (http://twistedmatrix.com)
an event-driven networking engine written in Python and licensed under the open source MIT license.
It's cross-platform and was preinstalled on OS X 10.5 to 10.12. Amongst other things you can start up a simple web server in the current directory with:
twistd -no web --path=.
Details
Explanation of Options (see twistd --help for more):
-n, --nodaemon don't daemonize, don't use default umask of 0077
-o, --no_save do not save state on shutdown
"web" is a Command that runs a simple web server on top of the Twisted async engine. It also accepts command line options (after the "web" command - see twistd web --help for more):
--path= <path> is either a specific file or a directory to be
set as the root of the web server. Use this if you
have a directory full of HTML, cgi, php3, epy, or rpy
files or any other files that you want to be served up
raw.
There are also a bunch of other commands such as:
conch A Conch SSH service.
dns A domain name server.
ftp An FTP server.
inetd An inetd(8) replacement.
mail An email service
... etc
Installation
Ubuntu
sudo apt-get install python-twisted-web (or python-twisted for the full engine)
Mac OS-X (comes preinstalled on 10.5 - 10.12, or is available in MacPorts and through Pip)
sudo port install py-twisted
Windows
installer available for download at http://twistedmatrix.com/
HTTPS
Twisted can also utilise security certificates to encrypt the connection. Use this with your existing --path and --port (for plain HTTP) options.
twistd -no web -c cert.pem -k privkey.pem --https=4433
go 1.0 includes a http server & util for serving files with a few lines of code.
package main
import (
"fmt"; "log"; "net/http"
)
func main() {
fmt.Println("Serving files in the current directory on port 8080")
http.Handle("/", http.FileServer(http.Dir(".")))
err := http.ListenAndServe(":8080", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
Run this source using go run myserver.go or to build an executable go build myserver.go
Try webfs, it's tiny and doesn't depend on having a platform like node.js or python installed.
If you use Mercurial, you can use the built in HTTP server. In the folder you wish to serve up:
hg serve
From the docs:
export the repository via HTTP
Start a local HTTP repository browser and pull server.
By default, the server logs accesses to stdout and errors to
stderr. Use the "-A" and "-E" options to log to files.
options:
-A --accesslog name of access log file to write to
-d --daemon run server in background
--daemon-pipefds used internally by daemon mode
-E --errorlog name of error log file to write to
-p --port port to listen on (default: 8000)
-a --address address to listen on (default: all interfaces)
--prefix prefix path to serve from (default: server root)
-n --name name to show in web pages (default: working dir)
--webdir-conf name of the webdir config file (serve more than one repo)
--pid-file name of file to write process ID to
--stdio for remote clients
-t --templates web templates to use
--style template style to use
-6 --ipv6 use IPv6 in addition to IPv4
--certificate SSL certificate file
use "hg -v help serve" to show global options
Here's another. It's a Chrome Extension
Once installed you can run it by creating a new tab in Chrome and clicking the apps button near the top left
It has a simple gui. Click choose folder, then click the http://127.0.0.1:8887 link

I found python -m http.server unreliable—some responses would take seconds.
Now I use a server called Ran https://github.com/m3ng9i/ran
Ran: a simple static web server written in Go
Also consider devd a small webserver written in go. Binaries for many platforms are available here.
devd -ol path/to/files/to/serve
It's small, fast, and provides some interesting optional features like live-reloading when your files change.
If you have PHP installed you could use the builtin server.
php -S 0:8080
give polpetta a try ...
npm install -g polpetta
then you can
polpetta ~/folder
and you are ready to go :-)
Using Servez as a server
Download Servez
Install It, Run it
Choose the folder to serve
Pick "Start"
Go to http://localhost:8080 or pick "Launch Browser"
Note: I threw this together because Web Server for Chrome is going away since Chrome is removing support for apps and because I support art students who have zero experience with the command line
Yet another node based simple command line server
https://github.com/greggman/servez-cli
Written partly in response to http-server having issues, particularly on windows.
installation
Install node.js then
npm install -g servez
usage
servez [options] [path]
With no path it serves the current folder.
By default it serves index.html for folder paths if it exists. It serves a directory listing for folders otherwise. It also serves CORS headers. You can optionally turn on basic authentication with --username=somename --password=somepass and you can serve https.
I like live-server. It is fast and has a nice live reload feature, which is very convenient during developpement.
Usage is very simple:
cd ~/Sites/
live-server
By default it creates a server with IP 127.0.0.1 and port 8080.
http://127.0.0.1:8080/
If port 8080 is not free, it uses another port:
http://127.0.0.1:52749/
http://127.0.0.1:52858/
If you need to see the web server on other machines in your local network, you can check what is your IP and use:
live-server --host=192.168.1.121
And here is a script that automatically grab the IP address of the default interface. It works on macOS only.
If you put it in .bash_profile, the live-server command will automatically launch the server with the correct IP.
# **
# Get IP address of default interface
# *
function getIPofDefaultInterface()
{
local __resultvar=$1
# Get default route interface
if=$(route -n get 0.0.0.0 2>/dev/null | awk '/interface: / {print $2}')
if [ -n "$if" ]; then
# Get IP of the default route interface
local __IP=$( ipconfig getifaddr $if )
eval $__resultvar="'$__IP'"
else
# Echo "No default route found"
eval $__resultvar="'0.0.0.0'"
fi
}
alias getIP='getIPofDefaultInterface IP; echo $IP'
# **
# live-server
# https://www.npmjs.com/package/live-server
# *
alias live-server='getIPofDefaultInterface IP && live-server --host=$IP'
I've been using filebrowser for the past couple of years and it is the best alternative I have found.
Features I love about it:
Cross-platform: It supports Linux, MacOs and Windows (+). It also supports docker (+).
Downloading stuff is a breeze. It can automatically convert a folder into zip, tar.gz and etc. for transferring folders.
You can file or folder access to every use.
I have Installed GTK on a Linux machine.
I am connecting To Linux Machine from a Telnet Session to compile the GTK programs
From A Windows Machine. I am using Cygwin on Windows Machine. but i am not able to see
GUI output of my GTK program on my Windows Machine.
When i run program from my terminal i get this error:
(helloworld:22576): Gtk-WARNING **: cannot open display:
I tried solutions from every answer posted, but no use now i am getting following error:
$ ./helloworld
Invalid MIT-MAGIC-COOKIE-1 key
(helloworld:22710): Gtk-WARNING **: cannot open display: 172.25.0.161:0
and i am getting following error on my Cygwin console:
client 6 rejected from IP 172.25.0.91 Auth name: MIT-MAGIC-COOKIE-1 ID: -1
You must set the DISPLAY variable in your telnet session to the IP address or DNS name of your Windows machine and append ":0"
export DISPLAY=windows.your.domain:0
And you must start an X server on the Windows machine (comes with Cygwin but you must start it).
You need to run the X window system (install with Cygwin) on your Windows-box and enable remote connections (probably with xhost). Set the DISPLAY-variable on your Linux-box to the address of your Windows-box and :0, as such:
export DISPLAY=192.168.1.123:0
I can recommend using ssh rather than telnet, for security reasons. In this case you do not need to enable remote connections with xhost, and you do not need to set the DISPLAY-variable. You only need to enable X forwarding.
You should install X-server on your windows machine and make sure you have DISPLAY set to yourmachine:0 or something like that. Or better yet use ssh instead of telnet (e.g. putty) and tunnel your X connection. You'll have to do a bit on your own research, though, because the complete answer would be a lengthy one.
Install an small X server on Windows XMing32, then run it, use putty as a console client, and check "X11 Forwarding" in Connection->SSH->X11.
Unfortunately, X11 Forwarding is not available through Telnet, you must run a SSH server on the target Linux and connect through SSH. (See if /etc/ssh/sshd_conf requires enabling X11 Forwarding too).
