Ssh connection refused for wp76xx

That is why you shoud capture wireshark log for investigation


I captured this via ethernet using wire shark.


I have used nmap and found that ssh port is closed and with ok device it’s open

is there any firewall setting in this device?

You might need to route out the UART2 hardware pin to log in the linux console of module

How can i check the firewall setting on an ok device ?

How about using “ip r”?

does this mean anything ?

Thanks, I will refer.

Is there AT command to enable ssh services ?

by default, if you enable CDC-ECM interface in AT!USBCOMP, ssh service should be enabled

Is it possible to disable and re-enable them ?

Please see the AT command user guide for the usage of AT!USBCOMP

Hey I have gotten the UART2 but how to access the linux console of module. I am just able to see some logs thats all.

what kind of log do you see there in UART2?

[10] QUP: I2C status flags :0x1363c8
[10] QUP: I2C status flags :0x11163c8
[30] QUP: I2C status flags :0x1363c8
[40] QUP: I2C status flags :0x11163c8
[60] QUP: I2C status flags :0x1163c8
[60] I2C slave addr:0x71 not connected

[70] ERROR: No misc partition found
[2010] SSMEM init OK[2010] ssmem_get: region 20 not exists[2110] DEBUG: cmdline has root=
[2170] Channel alloc freed
something like this

you need to check AT!MAPUART? in USB modem port to see whether you have set the linux console to UART2

its 17,17 should I change it to something else ?

you should change it to
AT!MAPUART=16,2

And then reset the module

I have done that and now still able to see logs but these are bit different.

can you log in and enter command there in UART2 console?

How to login in ? I have entered password but I am not able to see anything happening.
