OpenWrt don’t allow android's samba server /w unusual ports while stock firmware allow

ccchan · September 15, 2020, 2:34am

hi, thx but....

Yes, the ports are unusual, however,
the app landrive (a samba server app) on android was set to use the above 3 ports,
AND the win10 are set to use those 3 unusual ports too (by using the multi port forwarder).

So, even using a stock TP1ink C2 archer,
the modified android (on wifi) COULD communicate with modified Win10 (on LAN).

THE ONLY THING I changed is the router, from C2 to openwrt (commercial GL inet BrumeW, or self flashed openwrt 20.x D1ink 842).

So i think the problem lies on the openwrt routers' settings.

If you mean I need "connect/forward" unusual ports on android to usual ports on win10,
i think that's not the case, as both are using the unusual ports after both sides' modifications.

thanks

hi,
in all cases, PC is using LAN to connect to LAN port of router, while phone is connected using wifi.

Yeah the D1ink 842 is flashed with the lastest snapshot of openwrt.

How do you try to access your shares? Using IP or Hostname? For me it sounds like a name resolution issue. I can imagine that your TP-Link Archer C2 is running it's own samba server using Netbios/WINS (running as a master) to do name resolution for all samba servers and clients. This is not the case for a plain OpenWrt installation.

ccchan · September 15, 2020, 12:49pm

hi~

I always ping-ed the IP to confirm they can meet, also I always FTP into the phone
to make sure the connection is working. What strange is PC to PC using normal ports
are OK, with openwrt or TPlink stock. But the modified samba app and the modified ports on windows only work on TPlink stock and not TWO openwrt devices.
summary: the routers I only use them as router, it's the phone's app "landrive" act as
samba server, but using the 3 unusual ports as it's un-rooted.
The PC were the CIFS servers and the clients, as PC-A and PC-B can access each other's CIFS share.

thanks

krazeh · September 15, 2020, 1:02pm

The pc and Android device are in the same subnet right? I.e. they both have a 192.168.1.x address?

pwned · September 15, 2020, 1:12pm

I got this already. I want to know how your phone is accessing the share. Over plain IP or hostname? E. g. smb://192.168.x.x or smb://mypc
Did you try another SMB application on your phone. E. g. TotalCommander with SMB plugin?

ccchan · September 15, 2020, 1:14pm

yes,
for GL inet's brumeW, router is 192.168.8.1, PC could be 192.168.8.58 (58 is I chose,
as my laptop is T580 lenovo),
phone is 192.168.8.231 (231 is by default)

for TP link that will be 192.168.0.*
for self flashed openwrt Dlink it will be 192.168.1.*, as above.

for ALL combinations,
PC-A can ping others, FTP into others, got into another PC-B's CIFS (using normal port), it's just when android samba server app is used, due to un-root, the
samba server's port is different, and the PC, as a client, need install freeware multi
port forwarder and use the above 3 unusual ports.

btw, PC-A, even with the multi port forwarder ON,
can still reach PC-B's CIFS share, using normal ports.

thx

ccchan · September 15, 2020, 1:15pm

hi

the android samba server app shows itself using IP,
and indeep the PC-A can reach it either by IP or by hostname (xiaomi in my case).
my xiaomi is un-rooted, so LAN drive is the only samba SERVER app I knew of.

thx

ccchan · September 15, 2020, 1:18pm

LANdrive is the only android app I know that act as samba SERVER while you dont need the phone rooted i.e. it works UNROOTED.

ccchan · September 15, 2020, 1:21pm

provided every ping is working, every FTP into is working,
also every win10 to win10 CIFS normal port is working, (in all 3 router of stock TPlink,
openwrt brumeW, openwrt dlink 842)

and the landrive working in TPlink and NOT working with openwrt (two different openwrt).

I simply can conclude it's the openwrt somehow prevented the landrive from working.

I could further do a regular testing later when free.

thanks

krazeh · September 15, 2020, 1:32pm

I've just installed LAN drive onto my phone and installed multi port forwarder on my pc. It works without any issues or needing to make any changes on my router.

I would double check the IP address assigned to the phone when you use a different router and ensure that any change has been updated in the multi port forwarder rules.

ccchan · September 15, 2020, 1:39pm

wow is it!?

using the phone as samba SERVER?!

let me try again and let me close all win/android firewall then!

thanks first.

krazeh · September 15, 2020, 1:41pm

Yep, literally just installed the app off the play store and added the rules in multi port forwarder as described in their tutorial. Then just used my phone's IP address in explorer (i.e. \\192.168.1.x\) to connect and browse the local storage.

ccchan · September 15, 2020, 1:53pm

hi~

mind to try copy/move some files into the phone's share? becoz i could enter but it say "this folder is empty" but indeep it is not connected. thanks

krazeh · September 15, 2020, 1:58pm

I can only do limited testing as I don't have the full version and the trial is very speed limited, but I can open files stored on the phone from my pc so it's definitely connected.

ccchan · September 15, 2020, 2:06pm

ok, thank you.

i will check on my side, thanks

ccchan · October 11, 2020, 7:37pm

It's all MY faults, I apologize for this.
LanDrive WORKS perfectly with openwrt.

In Verigio, in the TCP tab, there is a hard code-ed IP address,
And after trial period, you can still USE it but you cannot CHANGE it.

So I setup my Tplink within the trial period, thus working well.
With the recently bought openwrt I forget/don’t remember there is a hard code-ed
IP address, so of course openwrt 's IP will never work with that.

Very much Thank you esp to Krazeh who helped by installing the app and software for me.
Thank you everybody.

(PS seems that one have to buy the ultimate version of
Verigio for working with LanDrive, which is 20USD….)

The tutorial of landrive is here:

The limitation of trial version of verigio is here:
