Semi automated shell program to manage OpenVPN

Post by antuelle78 » Fri Nov 24, 2017 11:04 pm

Hi Everyone,

This is my first post, admins please bear with me.

So back to the subject; I just finished writing and testing a bash shell script that can make OpenVPN management really simple.

It can generate any number of clients and deploy single or multiple clients to a single or several server instances.

A search feature to help locate clients in large deployments

Deploy server instances

Connect to management interface of any server instance.

I would like to share this code with the community.

Anyone interested in helping improve the code is welcome.

If this interest anybody, lets have some fun

Can someone tell me how I can upload the code?
The script has 744 line plus it needs the entire easy-rsa directory and some add elements to work

Its pretty simple code and is well commented. I am not a shell programmer!

Can a moderator help us?

Ok no responses hmm.. boring topic I think, maybe I am the only lazy person here.
I am gonna try to paste the search function to give an example
getinfo () {

clear
echo -n "Enter CN of client: "
read SRCHARG junk

echo `cat $SRVDEPD`

echo -n "Choose server IP from list of deployed instances or provide new host IP: "
read SRV2SRCH junk

echo -n "Enter management interface listening port: "
read SRV2SRCHPRT junk

ssh root@$SRV2SRCH "{ echo "status 3"; sleep 1; } | telnet 127.0.0.1 $SRV2SRCHPRT" | grep "$SRCHARG" > $SRCHRLT

}

OH that looks good, lets try the entire search function, maybe that will spark some interest:

#Search FUNCTION

srchclient () {

SRCHRLT=search_result
SRVDEPD=depsrv.dat

#FUNCTION to gather info and executer manual search

getinfo () {

clear
echo -n "Enter CN of client: "
read SRCHARG junk

echo `cat $SRVDEPD`

echo -n "Choose server IP from list of deployed instances or provide new host IP: "
read SRV2SRCH junk

echo -n "Enter management interface listening port: "
read SRV2SRCHPRT junk

ssh root@$SRV2SRCH "{ echo "status 3"; sleep 1; } | telnet 127.0.0.1 $SRV2SRCHPRT" | grep "$SRCHARG" > $SRCHRLT

}

#FUNCTION for recursive/multiple server querry for a client/clients

srvlst () {

clear
echo -n "Enter CN of client you are looking for: "
read SRCHARG

while read -r SRV2SRCH SRV2SRCHPRT
do

ssh root@$SRV2SRCH "{ echo "status 3"; sleep 1; } | telnet 127.0.0.1 $SRV2SRCHPRT" | grep "$SRCHARG" > $SRCHRLT

done < depsrv.dat

}


#SEARCH menu


echo " SEARCH MENU "
echo
echo " What do you wish to do? "
echo
echo " 1. Enter info manually "
echo " 2. Search from list of available servers"
echo
echo

#
# Prompt for an answer
#

echo -n "Answer (or 'q' to quit)? "
read ans junk

#Case statement to handle options

case "$ans" in

1)

getinfo
;;

2)

srvlst
;;

esac


#Display search results and remove results data:(, we don't store anything!!!

if [ $? != 0 ] ; then
clear
echo " ##NO RESULTS FOUND##"
else
clear
echo " ###SEARCH RESULTS###"
echo
echo
more $SRCHRLT
fi

rm $SRCHRLT

echo
echo
echo " HIT <<ENTER>> to continue"
read junk

#Check if user wants to do another search

clear
if yesno Do you want to try another server/client?
then
clear
srchclient
else
menu
fi
}
