[App] Network Packet Generator

hello all,
I've created this app that Generates TCP , UDP and ICMP packets
- the purpose for this app is to :
1- Flood a system, a port, or a server to demonstrate how the system will be raise the usage of the CPU which might result in shutting down PC
2 - Test firewall policies against connections from/to specific ports
3 - Educational purposes to get the idea of the Packets,connections and denial of service attacks
**The TCP and UDP packets are generated without root
ICMP may requires ROOTED
example of generating UDP packets :

No it's pure java coding
but you need root access for ICMP protocol only
note that when you use TCP or UDP protocols with port number 7 is an echo TCP or echo UDP
try to figure out the problem of google play store
hope you like it :laugh::good:

[Q] Help with port connection (ftp server ultimate)

Hmm i just posted this but can't find it anywhere. Apologies if double posted or it was deleted for some reason.
The target device:
No mobile network connection, it is on wifi only
Cm12.1
Static ip
General info:
Forwarded port through my router configuration page
Canyouseeme.org reports port is open on public ip
Problem:
Can connect via internal ip from other devices but when i switch to public ip the connection times out.
I did have the port forwarding configured wrong but now the port is open. Before it would refuse the connection. Now it just times out after waiting 3000ms.
Is there and Android setting preventing port connections?

failure message from ftp client on android device
Also fails from my regular ftp program via windows box

One thing that concerns me is my router lists my device as having a dhcp connection. The device connection is implicitly set to static and always uses the ip address i assigned it. It very much acts static but the router says dhcp. I don't think this is the problem. But it's still concerning.
Edit: terminal emulator using netstat confirms port 33133 is listening via tcp6
Edit 2: the problem is probably the device is listening using ipv6 and I'm trying to connect with my ipv4 address.
How can i force android to connect using ipv4, or connect to my device using ipv6 address? Admittedly i don't know much about ipv4 or ipv6.
Edit 3: I reset router and set up port forwarding again. Reset static ip to a different ip. Turned off ipv6 in router. The router now recognizes my device as static instead of dhcp. Changed the port number and canyouseeme.org sees the new port as open. However, ftp client still gets connection timed out error. netstat on the server device still recognizes that it's listening via tcp6 on the port (ipv6) which I suspect is the problem. I need to force my android ftp server device to connect with ipv4.

This is seriously giving me a headache! I bought a 5tb drive to connect via usb host cable and need the ftp server to keep offsite database backups of my websites. So, it's pretty important to me.
Anyways, I've disabled ipv6 at the router level and phone level (via app and script). Netstat still reports tcp6 listening.
Is this even the problem? It seems ipv6 is pretty popular on Android and the problem persists across multiple ftp server apps. Seems like the apps would be built with this in mind. I'm trying on my android 2.3 phone as well but i can't find how to make a static ip on gingerbread.

It was already disabled but by going into options and re-confirmed it was disabled it went away so hopefully it won't come back

use Quad9 instead
1)settings
2)connections
3)More conn settings
4)Private dns
dns.quad9.net
5)save and reboot

your Router or ISP blocks private DNS, try without wifi
install network tools and make Ping dns.quad9.net

[Samsung] Airplane mode broken / "More connection settings" crash

I've two problems on a Samsung phone (Android 10 / OneUI 2.5), likely caused by the same core problem.
Reset Network settings didn't help. I'm hoping to solve it directly, without factory reset or firmware reinstall.
Any idea how to debug further?
The two problems:
Airplane mode can't be toggled without a restart. Toggling in the Quick Settings, the button will just sit in an intermediate state:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Trying from the full settings page, under some conditions (not always) it looks like you can toggle it (status icons change), but nothing changes in practice, and the QS button will still stay in the intermediate state. The only way to toggle is to change in the full setting page, then restart the phone.
Entering "Settings \ Connections \ More connection settings" always crashes, due to:

Not sure anymore when the whole thing started, but it was long ago.
(Maybe the question fits better under "Android Development and Hacking"?
It's not specific to a Samsung model, and AFAICT there's no non-specific Samsung subforum.)
