Hello all, I am using OpenSSH_5.0p1, OpenSSL 0.9.8h and have following setup: First local port forwarding (specific ports are just for sake of example) on the local machine (used by several users simultaneously): ssh -L 7777:localhost:7777 some_user_name1@system1 Then the second user comes and sets up the section in following way: ssh -L 7777:localhost:7777 some_user_name1@system2 He is successful in setting the second port forwarding session. On attempt to connect to local port 7777 second user is forwarded to system1. In my opinion the behaviour is wrong, the second attempt should not work (with some error message like ambiguous port forwarding) , let alone the forwarding to system1 What would be your take on this? /wbr Ariel Burbaickij
