Something is blocking stun. Are you running any addons?

EDIT: I uploaded a 'wicens-lts-mod.sh' script. Download and rename to 'wicens-lts.sh'
This adds a fallback to use the router's internal WAN IP if the stun fails.

Updated to the latest release 48E2 on my RT-N16. Opened all the tabs. Browsed around. Everything seemed to be working ok. No issues with the GUI. Was excited to see the OpenVPN 2.5.1 being updated, then DoH! forgot that the N16 doesn't support OpenVPN, dang.

Additional thought: With @RMerlin's builds, more of the firmware has become/is becoming closed-sourced by Asus over time. Since we are still on the 374 firmware, does that mean that most, if not all, the firmware is still under GPL/open-source? I guess put another way, how does the still Open-source compare between the latest 386 builds of Merlin and the 374 builds of your fork, @john9527? I would imagine that there might be some on this forum that might be interested in this.

forking to Johns LTS was on a list of things to do but never saw an explicit request so I never got around to it, if there's success for users using Johns modified version Ill look at merging Johns edit to my github version

wicens was written to be a guided user entry experience hence the 1000 lines of user credential entry code, but as it was my first script it could use some better execution flow control and lots more finesse

What you want could be easily be accomplished a few different ways with much much less code like John mentioned in post #12 ;)

It doesn't work either, a shame.

Code:

Mar 10 17:16:00 crond[415]: USER admin pid 7428 cmd /jffs/scripts/wicens-lts.sh cron

Thanks anyway..

The following script I have tried it too and it DOES work.

ddns-start:

Bash:

# Custom DDNS (dynamic DNS) for the no-ip.com or asuswrt service for asuswrt-merlin
# The scripts works in a double NAT setup and single NAT setup, and will automatically detect the current configuration.

#Path to logfile leave empty if not used
LOGFILE=""

#Use cron to check for new ip every X minute.
#Leave empty if you're using the default from merlin (24 hours).
#Any previous, or if used, setting will be removed if left empty.
CUSTOM_UPDATE_INTERVAL=""

The only thing is that we should add the possibility of email notifications, but I do not think it is complicated since I use email notifications with other scripts.

This adds a fallback to use the router's internal WAN IP if the stun fails.
John looks like you removed the function export to the temp file which is where current_wan_ip is set from

Capture.JPG

Edit: Its exported to a temp file as in testing if setting current_wan_ip=$(F_getrealip) the 5 sec wait watcher for the stun lookup is borked and doesnt kill hung lookups

I moved the redirect into the function call itself....running directly from the command line it would hang the way you had it. Just trying different things.
The fact that the ministun fails when run by itself from the command line is the problem.

When I can I'll bring up my N66 MIPS and see if I can recreate (it's a bit disruptive to take down my main router and replace it)

Doh, my bad. At work right now, must have scrolled by the other change.

In testing on my N66 back in the day I was trying gettunnelip (didnt know about getextip) on your fork which did return my WAN IP but I think if someone is running a VPN this would show the VPN IP correct?

gettunnelip is just a link to getextip in my fork (it started life as gettunnelip, but was then generalized...I happened to pick a different name for the general version before Merlin did :) ). If you just pass a number (instead of a full interface name) it assumes you are requesting a tun interface.
 
But what does it tell you about your external WAN IP? What kind of config do you have? Are you double NAT? CGNAT?
No, I don't have double NAT and neither do CG-NAT. My AC66U is the main router.

My Internet connection is with FTTH and I only have one ONT before the router (it is transparent): I connect by PPPoE through VLAN20.
 
DING! DING!
I understand now....my getextip is not pppoe aware. I'll work on a new build for you to try.
Asus added a getrealip.sh script to the firmware a few years ago, maybe use that as a reference. It's on my Github under router/rom/apps_scripts/ .

Greetings.
If you can export it as a text file, you can use div-email (https://raw.githubusercontent.com/de-vnull/vnstat-on-merlin/development/scripts/div-email.sh) to draw from the Diversion email credentials and send a message.

See description here: https://www.snbforums.com/threads/b...tall-script-offline-for-now.70091/post-661765

And how I got it to work on the alpha version of VoM: https://www.snbforums.com/threads/b...tall-script-offline-for-now.70091/post-661889
 
@diamuxin @Maverickcdn

OK....there's a new build, 48D3 in the Development-Beta folder. Biggest change is PPPoE support in the stun script. I have no way to pre-test, but pretty sure it should work.

There's also a new wicens.sh script in the Scripts folder. Since I needed to open the code, I updated the firmware so that changes to to the wicens script are no longer necessary except for the firmware version check (1 line added, 2 lines changed). I also updated the version to 1.12

I'll keep my fingers crossed! :)
 
Wow John... you're amazing, if anything your willingness to go above and beyond (in my opinion) has reinvigorated me to get back behind the keyboard.

I won't be able to put in some consistent seat time for a bit but Ill look at adding 374LTS support to wicens and the request from maghuro on github for update support. I should be able to test against your beta build as well (not PPPoE though)

Do you remember what the issue here was specifically?
EDIT: I also refreshed the download wicens-lts.sh script to fix a problem removing the wan-event script when doing a reset.

And not to sway your thread or the discussion too much but @thelonelycoder was hinting he might be working on a stand alone Emailer script, it may be backwards compatible with 374LTS, but if it doesnt come to fruition I may look at doing it but Ill be quite busy until fall, I had started on such a thing myself and was designing a GUI interface for Merlins addon API but quickly realized I was well out of my realm of knowledge and it will take me 6months+ to learn/write/debug any such thing but it could retain some of the 1000 lines of CLI entry code for user creds to still work with 374LTS

Keep up the stellar work!
 
@Maverickcdn

I like to try and keep things with my fork as compatible as possible with Merlin, so this was a good exercise (I also enjoy debugging and fixing problems.....I know.....I'm strange :) )

On this one...

EDIT: I also refreshed the download wicens-lts.sh script to fix a problem removing the wan-event script when doing a reset.

I originally wanted to be able to rename your script to avoid confusion, but you had hard coded the script name in a lot of places. When I did a mass replace to make the name a variable, there was a sed command that referenced the script name that was constructed with single quotes that didn't expand correctly and needed to be changed to double quotes.
 
@diamuxin I made the changes to my script to accommodate the changes made by John to his firmware, you can install 48D3 and download wicens v1.12 from github

I wont be able to test it myself just yet so Im at your mercy
 
Hi!

I have followed the recommended steps in my AC66U:

1.- Updated my AC66U from 48E2 -> 48D3
2.- Installed wicens.sh script downloaded from @Maverickcdn 's Github (updated according to the latest script from @john9527 )

It works almost correctly already !! Congratulations!

Just a small problem (at least for me, hehe), the sendmail of this latest release does not work well, I have tried it with SMTP Gmail (587) and also with SMTP Outlook (587).

Wicens log:

I'm sure the problem is with FW 48D3, if you have modified sendmail and some part of the firmware that does not allow the use of the certificate (with 48E2 the scripts sent emails correctly). I have also tried from my NAS sending email from the same GMAIL account and it works fine, but nothing comes out of the router.

EDIT: It's funny, when I reboot (2 times) it, at startup, the script, for example, wan-start if it sends the email correctly but then sendmail no longer works.

EDIT2: Everything solved, it was a problem with my Gmail account (from). I have created a new account and now everything works fine.

Many, many, thank you for your great work!

EDIT3: Thanks also to @Maverickcdn for his great script!

Best regards.

sendmail is standard as part of busybox...nothing special in the fork.

One thing I found is that the mail servers I was using to send the mail would complain when using a custom 'name' for the sender (maybe a spam/security check). Try setting the sender 'name' to be the same as your sending email address instead of something like Asus Router
