Netcat on Sailfish
hi there, I found that nc is available in recovery mode but it isn't available in normal mode. Is there a way to use nc in normal mode??
We have moved to a new Sailfish OS Forum. Please start new discussions there.

Netcat is a small program, so it's far easy to compile and install:
-- Go netcat.sourceforge.net and download the source file (netcat-0.7.1.tar.gz)
-- Open Terminal or log into Sailfish through SSH. No need to devel-su, just proceed using the standard 'nemo' account.
-- Uncompress:
tar zxf ./Downloads/netcat-0.7.1.tar.gz
-- Enter directory:
cd ./Downloads/netcat-0.7.1
-- If you didn't previously, you must install a bunch of packages needed for compiling:
pkcon install gcc #(say Y when asked "Proceed with changes?")
pkcon install make
-- Configure:
./configure
-- Compile:
make
-- Install:
Option A: next step should be logging as root (devel-su) and type:
make install
Option B: but if you don't have Developer Mode enabled or you don't want to install stuff as 'root', just create a 'bin' directory at home:
mkdir ~/bin
Copy the Netcat executable (I'm renaming it to 'nc'):
cp -a src/netcat ~/bin/nc
and you're done.
-- The uncompressed directory is useless now. You can erase it (check the route carefully, 'rm -rf' is a very dangerous command; or just delete it with your favorite file browser)
cd ~/Downloads
rm -rf netcat-0.7.1

Remember that bash not only supports regular expressions but even features a working network stack.
This comes very handy in situations like this (debugging on a small embed device that might not have netcat installed on it, but has a not too out-dated version of bash on it).
If the netcat on you desktop/laptop is the one in listen mode in your pipe, than you can simply send data to it using :
echo "test" > /dev/tcp/${IP_DESKTOP}/${LISTEN_PORT}
and fetch data from it with
cat < /dev/tcp/${IP_DESKTOP}/${LISTEN_PORT}
where IP_DESKTOP
is the ip address of you laptop/desktop (e.g.: 192.168.2.13)
and LISTEN_PORT
is the port on which you instructed netcat to listen for connections.
It also works with UDP connection (using /dev/udp/
in bash, and nc -u -l
in netcat).
This way you don't need to install any RPM from an external repository (openSUSE repositories for armv7hl seem to work for me usually)

Bumping this as I'm also looking for netcat. I'm sure I saw it somewhere on openrepo's but I can't seem to find it anymore.
Niju ( 2015-09-26 18:24:16 +0300 )editI want to send an UDP message to my server, so netcat would be the easiest way. nc is absolutely basic functionality and is a must have!
Edit: Solved it with python script! This works out of the box ;)
SaimenSays ( 2015-10-08 00:17:44 +0300 )editFor out of the box with TCP and UDP, remember that bash can do it too (see answer below)
