🐾 Idefix Terminal — an ultimate terminal in your ASUS-Merlin GUI

[jksmurf]

I’m not sure what happened here, just tried to install using iTerminal on my iPad, it said installed successfully but then said failed?

I have not installed Idefix previously.

There’s no tab under administration as yet.

 

[RandomUser777]

Not sure what is happening, but I can't update to from 1.3.0 to 1.4.1.

I get some strange errors in the cli:

wget -O /tmp/idefix-install.sh \

and then I get stuck with this on the GUI:

And once that happens, "idefix uninstall" does not work since idefix is not found. I have to roll back via backups to v1.3.0, which works fine .

Any thoughts?

 

[MegaMango]

honestly, I am a bit lost why this cause the issues... so far I blame `.asd` service...

@RandomUser777 @jksmurf
can you try 1.4.2?

Ermmm .. unfortunately nope, not for me…

 

[RandomUser777]

@MegaMango any chance you could roll back to 1.4.0 while the code/errors are examined? I was actually able to install 1.4.0 successfully just before you updated to 1.4.1 and 1.4.2.

yes sure, you can simply run

idefix update 1.4.0

I just really surprised it fails for all others...

a stupid long shot

idefix update

also don't help?

Same here 1.4.0 worked, 1.4.1 and 1.4.2 not so much.

 

[RandomUser777]

I was able to upgrade to 1.4.0, works just fine. However, when I updated to 1.4.2 somethings breaks - calling for idefix at the cli reports "idefix: not found".

 

[RandomUser777]

In order to install 1.4.0 fresh, I had to get the install file, edit it to "sh /tmp/idefix/idefix update 1.4.0", and then execute.

 

[jksmurf]

a stupid long shot

idefix update

also don't help?

I’m not sure what you mean here.

As Idefix is not installed (does not install) I never tried Idefix update.

To confirm I just tried it and as expected Idefix is not found.

@jksmurf @RandomUser777
yeah, I think i got it fixed in 1.4.4 - Asuswrt Signature Detection (asd) has started to quarantining `/jffs/scripts/idefix`, no idea why. So I moved the entire script into /jffs/addons - this is actually the right place for it.

Working for me on an RT-AX86U running 3004.388.11_0, thanks @MegaMango.
Had to do a couple of rounds of uninstall/reinstall as I was getting weirdness but it came good in the end ...

Coolio... thank you!

Well when I saw the SSH log I was not too hopeful as there seemed to be 3 errors BUT this time it did indeed add the Idefix Terminal tab to the WebGUI.
Played around with it, it seems to work OK, the quick commands are awesome.... so... should I be concerned about the errors, can we make them go away so my OCD does not bother me at night .

And finally, will there be any leftover remnants from the several failed installs that I need to get rid of; and if so where? I could not see a /jffs/scripts/idefix dir but I do not know if there are others,

... and no way do I want to hide the Dog Idefix, I love Asterix and Obelix, I still have the full set and quote it regularly!

thanks man!

no, those are just cosmetics. Fixed them in 1.4.5, but if 1.4.4 works - no need to update.

 

[jksmurf]

Sorry to bother you again but I went in and updated from the Addon itself to see how that went and it updated but oddly jumped out to the Blue Reconnect button. More on that button below, because it starts to become very familiar…

I thought nothing of it at first, but then went and did a little poking around in the quick menus and ran a few things and sometimes the terminal screen jumped back to the shebang but mostly it seemed to run the command, which you can see faintly in the background, then showed me that blue reconnect button.

Wondering if there’s something amiss in my install, or if other folks are experiencing the same thing?

 

[JGrana]

I am experiencing the same. I did note that we both have RT-AX88U-Pro routers.
I can do a number of commands like pwd, cd - simple things. If I try “ls” it starts to output but then bails and show the reconnect button.
Ive tried in both Safari and Firefox.

 

[scootertramp]

just made a tiny patch for a 1.4.1 to fix the syslog timestamps, that some users previously reported and I missed this.

Running the latest idefix version 1.4.5.


Still seeing time warp in messages timestamps when starting idefix.
