Homebrew Question Why won't my FTPD work?

[laramie]

Like I said, nmap is overkill for this.
It could also mean that the IP can't be reached at all, as ping timing out implies.
Just check the IP of other wireless devices on the same WiFi network and see if they are in the same range.

nmap was just an easy way for OP to input commands that they felt were easy enough for them to put in and kinda understand, plus nmap is used everywhere and has amazing docs and support with a lot of topics where any problem OP runs into can be walked through pretty easy.

my mobile phone ip address is 192.168.68.102. i installed termux and it seems to be pinging it if:
64 bytes from 192.168.68.115: (other stuff)
is pinging it

Edit: I canceled it and it said that all packets were transmitted and recieved

yeah, if you get packets that means it did connect and send/receive data of some kind.

So does that mean that my phone can send data to my switch but my computer cant?

A correctly formed ping packet is typically 56 bytes in size, or 64 bytes when the ICMP (Internet Control Message Protocol) header is considered. So it went through your router and was pushed through with some checks from router, it means that it talks just fine to the network with sending and receiving packets. aka ICMP is used for timeouts

Then you have a firewall or routing issue between the wired network and the wireless network.

Now let's check your network topology.

Is your PC on the same router as your WiFi devices?

What is the default gateway for your phone?

See what the following command in termux returns to you (ip route show table 0 | grep "default.*wlan")

Pretty much, as of now, yes.

well yes and no, it means that you pc most likely has a firewall stopping your traffic where your phone doesn't. Both "work" but your pc is being blocked by your firewall. Disable all of windows firewall settings and try again please.

The router itself could have a firewall active as well.
It also could prevent both networks from contacting each other, but yes, windows/antivirus firewall could be causing the issue, though it's unlikely seeing as the networks are different.

 

[laramie]

It could be an expired TLS as well that's not playing nicely. All your times on switch and pc are right correct? That is checked when connecting internet things. For sync purposes and time related stuffs

OP said he can't get into router/modem until tomorrow because it's not his, I recommended that in like pg 2 lol

1) yes, my pc is on the same router as my wifi devices.
2) How do I find my default gateway on my phone
3) do you want my pc default gateway?

TLS/SSL/dates do not matter for basic, insecure TCP/IP connectivity.
If it's indeed the router's firewall, we could use some "creative" ways of bypassing it
If it's the router's routing rules, there's not much than can be done without using an external (as in on the Internet) device as a MITM proxy.

1) Nice, so it narrows down stuff to your router.
2) You just did with that command: It's 192.168.68.1.
3) Do better: run route print -4 so we can see the full routing table on your PC.

default router/modem IP is usually 1992.168.1.1 or whatever your networks subnet is configured to. You can check by just typing your router/modem into your pc browser and if you load a login page that's the IP.

I disabled all my firewalls

yeah it's like 90% probably your router's built in firewall.

 

[TheRealMrBuushy]

oh, then yes, 192.168.0.1 is the correct default

 

[AlexMCS]

There's no routing issues on your PC from that table.
And since no firewalls are up and your phone can connect to the switch, it's the router config, no way around it.

If you're in a hurry to send stuff, just send it through your phone, it will work.
Otherwise, you'll need to change your router settings.

Fun. the problem most likely lies in the 1 thing I currently don't have access to...

 

[TheRealMrBuushy]

Once I gain access to the router, what should I do?

 

[laramie]

ummm that's an interesting netmask IP..... I don't think that is good lol that means it would use every possible IP which could be why you are timing out..

--------------------- MERGED ---------------------------

Go to firewall settings and make custom config for your PC. (Allow your PC IP to bypass or have no restrictions through router firewall)

This makes no sense IMO.

You'd need to find settings related to network isolation or firewall.
Post it here or PM me for extra help.

0.0.0.0 isn't a valid netmask for a local IP address. The IPv4 private spaces are (in CIDR notation, thanks to ARIN.

--------------------- MERGED ---------------------------

The net mask 0.0.0.0 (in CIDR, /0) denotes "Every address to exist in all the universe" which is an invalid netmask for a specific IP range - you typically only see this with the IP address of 0.0.0.0, which with CIDR is 0.0.0.0/0 denotiong the entirety of the Internet.

I know Laramie. I am a network admin. I solve network connection issues for a living
Check your own PC and you will find the same 0.0.0.0 entry for your default gateway, since that is what "default gateway" means: the gateway used by default for all connections if there is no other entry in the table.
