Updater for Linux in c++

place the bid onyl if you have very good expirince with linux system programming in c++

Updater for Linux in c++

The linux updater is started every 3 hours by a cron job.

download a zip file from a https server

extract the files inside the zip to a temporary file.

check if the files has a valid signature

cancel if the files are not newer than the existing files

stop our daemon

copy the files to destination

set the user and the permission for the files (chown / chmod)

start the daemon

the configuration is in /etc/[login to view URL]

zipfile= [login to view URL]

tempfolder= /var/proupdate/temp

pubkey = 1234AF …

destination= /var/pro/

user= prouser

chmod= prod,proagent

stopdaemon= systemctl start protond

startdaemon= systemctl stop protond

the cronjob start /var/pro/proupdate without any parameter

installing the cronjob

if we start proupdate with parameter -cron it create a cron job (onyl if the cron job does not already exist)

the logfiles are written to /var/log/[login to view URL]

i need the version without the signature checking today .. or till tomorrow.

checking the signature can be added till next monday

the app does not depend on any external application or library.

i needd the sourcecode incl a make file, so that i can compile with gcc

proupdate run as root

pls write in the bid “ireaditall” … so that is see that you read this document.
