**use for reconfig grub for fix stuck at initial ramdisks:**

how does i get out stuck at initial ramdisk:

- first, access local os:

```bash
mount /dev/sda2 /mnt
mount /dev/sda1 /mnt/boot
arch-chroot /mnt/
```

- second, remove all initframs and vmlinuz, amd-ucode on `\boot`

 - third, copy each vmlinuz from `usr\lib\modules` to boot

example:
```bash
cp \usr\lib\modules\6.10.10-lts..\vmlinuz \boot\vmlinuz-linux-lts
```

 - forth, check on `etc\modprob.d` have any file `.conf` if it exist remove it

- fifth, reinstall amd-ucode `pacman -S amd-ucode`

- six, run `mkinitcpio -P`

done!

## SSH tunneling 
1. first u must have port 22 available on 192.168.1.1 virtual trigger 
2. uncomment `port 22` on file follow path `/etc/ssh/sshd_config`
-> after that u can connect to ssh. it means u doesnt need add open port 22 

## Open port 
-> This is depend on your method firewall u have 
-> in my case, i have `nftables` 

- `sudo nft -a list chain inet filter input` : list current port and rule was accepted 
- `sudo nft add rule inet filter input tcp dport 8505 accept` : add open port (in case is 8505)
- `sudo nft add rule inet filter input tcp dport '{ 8501-8509 }' accept` : add open port range 
- `sudo nft delete rule inet filter input handle 16` : if u use command `list chain` (first command) u will see a number for each rule to replace for a number 16
