linux-serverbot's Issues

Feature Alert: check best option for arithmetic comparison operators

Argument validity gets checked

Want to find some way of checking the validity and combination of arguments given.

Add function method_telegram to alert

It still uses the old code. This should be fixed.

Feature Manage Cron

Cronjobs should be managed by the argument --cron. It would be even better if there could be only one cronjob file, but this might add too much code.

Feature Alert

Base alert feature that checks cpu load, memory consumption and disk usage.

Make the use of requirement_os and gather_information_distro consistent

Feature Alert: USB monitoring

Check whether it's possible in a sort-off real-time way.

Feature Install & Update

Serverbot should be able to install and update itself.

Add main function

To follow conventions, the main code should be in the function main.

Feature Alert: use grant total option in df

Feature Alert: CPU / HDD temp monitoring

Check whether it's easily possible in a somewhat generic way for linux.

Feature Alert: do something about excessive length of free -m in Telegram

Check whether gather_metrics_memory can be simplified

By using else instead of if for all the newer distro's.

Make breaks/white spaces consistent

In if statements
In functions
In error texts
In feature outputs
Etc.

Feature Overview: show logged in users

Only [if] there are users logged in.

Merge if statements in function serverbot_cron

With elif

Support: old versions of Ubuntu

Ubuntu 14.04 LTS (Trusty Tahr)
Ubuntu 14.10 (Utopic Unicorn)
Ubuntu 15.04 (Vivid Vervet)
Ubuntu 15.10 (Wily Werewolf)
Ubuntu 16.04 LTS (Xenial Xerus)
Ubuntu 16.10 (Yakkety Yak)
Ubuntu 17.04 (Zesty Zapus)

Ubuntu 18.04 LTS (Bionic Beaver)
Ubuntu 18.10 (Cosmic Cuttlefish)
Ubuntu 19.04 (Disco Dingo)
Ubuntu 19.10 LTS (Eoan Ermine)

Add more combinations of arguments

Now some combinations of arguments just don't do anything. These should also give an error.

Make variables inside comparisons consistent

Sometimes I used "${VAR}", sometimes only "$VAR". These should be consistent.

Add good intro text in script

So newbies can find their way more easily :).

Feature Alert: ssd life expectancy

Might be best to include in feature alert.

Change Method Telegram parse mode to HTML

https://core.telegram.org/bots/api#html-style

Make automatic update possible

Of course just downloading a new version every week is possible with a cronjob, but I would much rather use something that checks of there are updates available first.

Options to investigate:

GitHub API that lists the latest date changes were made?
VERSION-file that consists of a variable for the version, that gets checked daily for a higher number.

Stand alone operation

Serverbot should be able to function without a config file, with some default values that get used when the config file isn't available.

FreeBSD support

Check whether Serverbot can be made compatible with FreeSBD.

Memory overview in feature metrics doesn't work on older distro's

The variables stay empty.

Echo's in error functions are not consistent

#############################################################################
# ERROR FUNCTIONS
#############################################################################

function error_invalid_option {

    echo
    echo "serverbot: invalid option -- '$@'"
    echo "Try 'serverbot --help' for more information."
    echo
    exit 1
}

function error_not_yet_implemented {

    echo "[!] Error: this feature has not been implemented yet."
    exit 1
}

function error_os_not_supported {

    echo
    echo '[!] Error: this operating system is not supported.'
    echo
    exit 1
}

function error_method_not_available {

    echo
    echo '[!] Error: this method is not available without Serverbot configuration file.'
    echo
    exit 1
}

Put errors in functions

That should make managing them easier.

Make telegram api calls silent

It can already upgrade, but should be able to install as well.

Make it possible to run script as normal user

Not all features can run as normal user, but the features that can be run as a user should not require root priv.

Feature Generate Config

When user wants to go from stand alone mode to config mode, it should be made easy for him/her :).

Feature Overview

Add new feature so show a more complete overview of the system. With stuff like:

hostname
ipv4
ipv6
uptime
OS
kernel
cpu
ram
disk

Should be easy to implement since all gather functions are already there.

Add uninstall in serverbot

Unset variables in serverbot

It seems hardly common that something else uses one of the variables I use, especially global ones. But just to be safe I could take a look at unsetting the vars first in the script.
