Create SWAP file on ASUSWRT Merlin

[raduzl74]

Hello!

I need a tutorial for creating a SWAP file (I am a beginner so as detailed as possible will be highly appreciated).

Thanks!

With no other info given, the link below may or may not be helpful.

Just note that you will not need to 'install' amtm if running RMerlin 384.15_0 or later (it is built into the firmware), but the rest of the steps are still applicable and as basic as they can be.

Here is the old but reliable way: https://mydevtutorials.wordpress.com/2014/01/10/how-to-activate-swap-on-asus-rt-ac68u-router/

And, I find a swap partition is more reliable. Swap files can be corrupted.

The old way isn't recommended any more. Particularly with amtm compatible scripts.

I'm more inclined to ask what router (and firmware) you have and why do you feel you need a swap file.

If you are having a specific issue, maybe you could describe it. A swap file may or may not be an appropriate"fix".

I just SSH in and use the amtm swap creation option.

The only thing that puzzles me is why amtm won't let me make a swap file bigger than 2gb.

Rule of thumb for Linux swap is equal to RAM size. Am sure the AX88U does not have 2 GB RAM. Even with the amtm apps you will not need 2 gb. Am sure others will, disagree with this....

Well it set it anyway since it was "recommend" by the installer, thanks for the advice I appreciate it.

2GB of swap is required to prevent the "Cannot fork" errors on HND devices. Any amount lower will cause this to happen when using custom scripts that spawn lots of processes.

I have an RT-AC87U, the issue being that sometimes in the morning the router needs a push to start (turning on a laptop solves it but no mobile phone manages to get traffic...)
I am on Merlin 383.13_10

I solved it. Inatalled entware, made swap 2 gb and also skynet. testing now to see how all works
