Trouble receiving telegram notifications when connecting to a VPN server?

Question

linux

I want to set up notifications in telegrams when connecting to a vpn server. I do it according to the instructions https://www.your-it-consultant.ru/post/libreswan-i...
Created a bot, created a script, made it executable, launched the script, a test notification came to the cart, now you need to bind it to connect events and disconnect, I do as described in the instructions in the /usr/lib/ipsec/_updown file and add the following lines:

case "$PLUTO_VERB:$1" in
....
up-client:)
        # connection to my client subnet coming up
        # If you are doing a custom version, firewall commands go here.
       /usr/local/bin/tg_say.sh User ${PLUTO_USERNAME} with ip ${PLUTO_PEER} is CONNECTED
        ;;
down-client:)
        # connection to my client subnet going down
        # If you are doing a custom version, firewall commands go here.
        /usr/local/bin/tg_say.sh User ${PLUTO_USERNAME} with ip ${PLUTO_PEER} is disconnected
        ;;
....

But for some reason, when connecting to vpn, notifications do not come to the cart, tell me, maybe something else needs to be registered somewhere?

Answer 1

Because the article is about Pluto and IKEv1, and you use IKEv2 and Charon.

Answer 2

Just in case, I’ll write a solution here: I
added a parameter to /etc/ipsec.conf:
leftupdown=/usr/lib/ipsec/_updown
and added 2 lines in the /usr/lib/ipsec/_updown script itself:

...
case "$PLUTO_VERB:$1" in
...
up-client:)
        # connection to my client subnet coming up
        # If you are doing a custom version, firewall commands go here.
        /usr/local/bin/tg_say.sh User ${PLUTO_USERNAME} with ip ${PLUTO_PEER} is CONNECTED
        ;;
down-client:)
        # connection to my client subnet going down
        # If you are doing a custom version, firewall commands go here.
        /usr/local/bin/tg_say.sh User ${PLUTO_USERNAME} with ip ${PLUTO_PEER} is disconnected
