I'm trying to create a scenario to test a simple ssh tunneling, just for using a simple telnet.
I have two hosts: ubuntu and suse. Both of them have the other hostname on /etc/hosts file for address translation.
Ubuntu: I verified and I can connect perfectly via telnet on port 23, as well as ssh via port 22 (with all id_rsa.pub and stuff in order to login via ssh without typing password).
On suse I tried:
ssh -f ubuntu@ubuntu -L 9000:ubuntu:23 telnet localhost 9000
then I get:
suse@suse:/etc/ssh> telnet localhost 9000 Trying ::1... Connected to localhost. Escape character is '^]'. channel 2: open failed: administratively prohibited: open failed Connection closed by foreign host. suse@suse:/etc/ssh>
Any ideias of that error?
