Okay, this explains it :)

* SSH, TELNET, and WEBSERVER all register listeners for incoming calls. There
  is a possible security issue here as those calls may come over cellular
  networks (not just wifi). There is no firewalling of these calls. It seems
  that the correct approach to this is to validate the destination IP to
  make sure it is a wifi interface IP address; but this is not currently
  done.

Hi,

 

I have been strugling getting SSH working for some time now. Tried both password access and key auth. I think the same issue was discussed before for V3, but I have not seen the final rezolution. 

 

Verbose output from client side:

 

debug1: Local version string SSH-2.0-OpenSSH_7.6p1 Ubuntu-4ubuntu0.3
debug1: Remote protocol version 2.0, remote software version wolfSSHv1.1.0
debug1: no match: wolfSSHv1.1.0
debug1: Authenticating to 192.168.0.157:22 as 'ovms'
debug1: SSH2_MSG_KEXINIT sent
Connection closed by 192.168.0.157 port 22
 

Regards,

Jaunius
