Any issues for the following message on an RT-AX88U with latest RMerlin version?

Code:
Aug 27 16:44:00 wan-failover.sh: System Check - ***386.8 is not supported, issues may occur from running this version***

Just switched over to V1.5.7-beta1c, wish I would of had it for Friday August 26th with debug logs on (only notice logs), as I had my ISP01 go down for real, and with V1.5.6 Final, it switched automatically to ISP02, and all services worked great.

ISP01(1GB Symmetrical) was down for almost 8 hours, but ISP02(650DL/100UL) just kept chugging along. When ISP01 finally came back, it did switch back over to ISP01 from ISP02, but the weird thing is ISP02 was then considered in a down state for almost 8 hours before my RT-AX88U sent out this message in the V1.5.6 Final notice logs:

Otherwise it failed over like it should and failed back like it should. Unfortunately no WFH was going on at the time, streaming, gaming, or VPN connections, to see any real time disconnects/reconnects.

Do you have logs you can forward for me?

Here is a run where:

1. Disabled QoS manually prior to update (as I noticed QoS was on again)

Continued..

Weird no debug logs about QoS enable/disable from the script. Perhaps it isn't reading my conf file correctly?

3. Noticed QoS was enabled again, so manually disabled it. Will check the code to see how you are calling it and when.

I have a question on QoS. How well would this script handle Cake QoS?
 
That would be great, as my two connections have different upload rates. Also, how would this affect my vpn client connection? It stays online 24/7.

Should re-establish once failover/failback is successful. I run 2x VPN servers on my router, and clients have no issue connecting (assuming DDNS updates correctly). I expect the reverse to be true unless your VPN server is looking for specific IPs to accept connections from (hardly likely).
 
I know I have covered this before but I can’t remember the answer. I show 3 identical cron jobs for this script. I just rebooted the router and the results are the same.

I cleared it up by issuing the following commands. Now it only shows 1 cron instance for the script. I have no idea why it happens, but not a big deal since I now know how to correct it if it happens in the future.

I am sure it’s something I am doing that’s causing this anomoly. :)

sh /jffs/scripts/wan-failover.sh kill

sh /jffs/scripts/wan-failover.sh restart

I think if you just do "restart" it will do the kill and restart for you. @Ranger802004 would be able to confirm.
 
Sorry for the delays guy, was a busy weekend for me so I am going to work on this tonight and hopefully get another beta out this week.

I tried that but it did not clear out the extra cron jobs. I am running the released version of the script, not any of the beta versions.

Restart won't delete the cron jobs but "kill" will, run it a few times to get all of them deleted. I may make that do a for loop to keep removing until it is empty of cron jobs. Not sure how the duplicates are getting in there since it's a check for it existing before adding a new one. Rerun "cron" to reschedule a new cron job after they are deleted. Also this won't technically hurt anything having multiple entries for the cron job, once the script is launched and locks the lock file, no other instances will run until that one is closed.

Just noting that I’ve also seen “doubles” of your cron job quite a few times, though only after reboots, over the last few weeks of my testing across many betas - so there are definitely cases where your “check for duplicates” is not catching them.

Hmmm I wonder if multiple wan-events simultaneously is causing that to happen where they both query null returns and issue the add command. I will come up with a locking method for that and see if that helps remedy the issue.
 
v1.5.7-beta2 has been published, enable DEVMODE and run update.

This beta fixed the following issues with v1.5.7-beta1.
- Fixed issue with QoS settings not being applied at start up
- Fixed issue where multiple cron job instances were being ran potentially creating multiple Cron Jobs
- Continuous improvement in email functionality
- Fixed issue were deprecated option for PACKETSIZE kept logging it would be removed.

v1.5.7-beta2
Installation:
- Fixed during Uninstallation where Cleanup would error out due to not having configuration items loaded prior to deletion of configuration file.
- Fixed text formatting for debug logging during installation when selecting WAN IP Address Targets.
- If QoS is Disabled QoS Settings will Default to 0 instead of prompting for configuration.

Enhancements:
- Configuration Mode will instantly kill script and wait for it to be relaunched by Cron Job.
- WAN0 and WAN1 can be specified to have QoS Enabled or Disabled during Failovers.
- WAN0 and WAN1 Packet Size can be specified seperately in Configuration File.
- Custom Log Path can be specified for Monitor Mode using CUSTOMLOGPATH setting in Configuration Settings.
- Added Dev Mode to update to beta releases using Update Command
- Service Restarts triggered by USB Modem failure events when it is not the Primary WAN will only restart OpenVPN Server instances.
- Added Configuration Option CHECKNVRAM to Enable or Disable NVRAM Checks due to only certain routers needing this check such as the RT-AC86U.
- New Status UNPLUGGED for when a WAN interface connection is not physically present.
- Added Cron Job Mode Lock File to ensure only one instance of the cron job function can run at a time to help prevent duplication creations of the cron job.

Fixes:
- Configuration Mode will no longer delete new or current IP rules/routes and will delete old ones before restarting script.
- Switch WAN function will now properly check Default IP Routes for deletion and creation.
- Load Balance Mode will now properly get default WAN Status before performing checks
- Emails not generating when some scenarios of Secondary WAN failure occur in Failover Mode.
- Fixed issue where missing configuration items weren't checked with option name exact matches as well as for removing deprecated options.

Looks much better in regard to QoS disable/enable based on settings in conf. Will monitor.

I'm the new guy in this thread... I may ask a "dumb" question. (be gentile)

Has anyone tried this script with a USB (cellular) Backup modem?
