Connection refused in Test-Setup #50

Closed KoEnix closed 8 months ago

KoEnix commented 8 months ago

Hi, i got a problem, which i cant find the error in. I got a small test setup with coturn, and when trying to scan a ssh port lying behind the coturn, I always get a "Connection refused. Could you maybe help me find the error?

The Lab-Setup: "External" "Internal" Host-Network <------------> CoTurn VM <---------------------------------------> Small SSH 192.168.178.100 192.168.99.128 192.168.99.129

My Call: ./stunner tcp-scanner -u securetest -p buzzw0rt -s 192.168.178.100:3478 --ports 22 --ip 192.168.99.129 --timeout 60s

ERRO[0000] error on running HTTP Scan for 192.168.99.129:22: error on establishing control connection: error on establishing a connection to the server: dial tcp 192.168.178.100:3478: connect: connection refused

Debug Log from Stunner: debug.log

COTURN-Config: turnserver.conf.log

Log from COTURN-server TURN-error

SSH is reachable from the coturn itself.

Is it maybe a test-lab-setup error?

The error message means that you can't reach 192.168.178.100:3478 via TCP. Maybe it only supports UDP or a firewall is restricting access? What's the output of stunner info .... ? Also be sure to use the latest version from github as there where a lot of connection related bugs in previous versions
