Cron job example to restart VPN

[ASadani]

Can anyone help with how to restart astrill, below are the samples I've collected?
how can I add this to the init-start script?

# execute at 4 am daily.

cd /jffs/scripts
/jffs/scripts/init-start
#!/bin/sh
cru a ScheduledVPNRestart "0 4 * * * /dev/astrill/astrillvpn stop"
sleep 5 <<< Will this work?
cru a ScheduledVPNRestart "0 4 * * * /dev/astrill/astrillvpn start"

 

[JDB]

Do all 3 commands in 1 cru job separated by semicolons

You may need to find the path to sleep and prefix it.

This assumes “/dev/astrill/astrillvpn restart” doesn’t work!?

Is the command correct? 04 ***? Do I have to append this command in init or will the cru be sufficient? Can I remove this if needed? sorry for the questions. I'm gonna try it out now.

 

[JDB]

The command I gave needs to go in the init script replacing the 3 line you suggested.

I can’t tell you is 0 4 * * * is correct as you didn’t say what the goal is. This will run the string of 3 commands every 4 am.

"04 ***" would not be correct because you have removed the spaces. Leave the spaces in as shown by @JDB and the wiki.

Thanks so much. I'm trying vi. Not too good at it but will try. Would have liked an ftp file but this is what I made.
The first lines are from the applet. Do I need to add a colon in the end and fi like the above line?

#!/bin/sh
if [ -e /jffs/astrill/nvram/astrill_bootstrap ]; then eval `cat /jffs/astrill/nvram/astrill_bootstrap`; else eval `nvram get astrill_bootstrap`; fi
cru a ScheduledVPNRestart "0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start"; fi << Is the ; and fi required.

This is my final file.

#!/bin/sh
if [ -e /jffs/astrill/nvram/astrill_bootstrap ]; then eval `cat /jffs/astrill/nvram/astrill_bootstrap`; else eval `nvram get astrill_bootstrap`; fi
cru a ScheduledVPNRestart "0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start"

Sorry, I know nothing about astrillvpn or the commands to make it work.

The line was there earlier. I just added the additional line below it. I'll check in the astrill logs tomorrow to see if the connection has restarted at 4:00 AM. If not then it didn't work.

If you do a “cru l” then paste the command part it gives you (not the whole line) in and it works; it’ll work at 4am too

I tried this and it didn't restart. I guess it won't work then

admin@RT-AC86U-26C8:/tmp/home/root# cru l
0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start #ScheduledVPNRestart#
admin@RT-AC86U-26C8:/tmp/home/root#

I also tried this and got this.

admin@RT-AC86U-26C8:/tmp/home/root# cru l /dev/astrill/astrillvpn stop;sleep 1;/
dev/astrill/astrillvpn start
0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start #ScheduledVPNRestart#
Already connected
admin@RT-AC86U-26C8:/tmp/home/root#

 

[JDB]

You didn’t do as I suggested so no surprise it didn’t restart

You need to copy part of the output cru l gives you back in to test the command [emoji2357]

I think I tried that and got the response "already connected"

1st Example of try:
cru l
0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start #ScheduledVPNRestart#
admin@RT-AC86U-26C8:/tmp/home/root#

2nd Example of try:
cru l /dev/astrill/astrillvpn stop;sleep 1;/
dev/astrill/astrillvpn start
0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start #ScheduledVPNRestart#
Already connected

Remove the cru l from start of the 2nd attempt

That part is making the stop command fail, so the start gets the already connected response

I think it worked, However, I just tried the one in red and not the one in blue which is suffixed in the script. #ScheduledVPNRestart#

admin@RT-AC86U-26C8:/tmp/home/root# /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start
Disconnected
Connecting...
admin@RT-AC86U-26C8:/tmp/home/root#

The Actual Script looks like this
#!/bin/sh
if [ -e /jffs/astrill/nvram/astrill_bootstrap ]; then eval `cat /jffs/astrill/nvram/astrill_bootstrap`; else eval `nvram get astrill_bootstrap`; fi
cru a ScheduledVPNRestart "0 4 * * * /dev/astrill/astrillvpn stop;sleep 1;/dev/astrill/astrillvpn start"

Thanks so much for your guidance. I'll revert back tomorrow to let you know if it worked. hopeful

 

[JDB]

Pretty sure it will based on the above [emoji106]

Wanted to confirm that the script successfully executed and the vpn restarted at sharp 4 AM. the restart completed at 4:00 AM and 4 Seconds. Awesome thanks for making this a success.

Thanks to you @JDB and @ColinTaylor
