If yes, than I suspect some problem on the level of my system setup because the log looks like =============== debug3: send packet: type 50 debug3: receive packet: type 52 Authenticated to 127.0.0.1 ([127.0.0.1]:4242) using "publickey". debug1: Remote connections from LOCALHOST:3301 forwarded to local address 127.0.0.1:4242 debug3: send packet: type 80 debug1: Remote connections from LOCALHOST:3302 forwarded to local address 127.0.0.1:4242 debug3: send packet: type 80 debug1: Remote connections from LOCALHOST:3303 forwarded to local address 127.0.0.1:4242 debug3: send packet: type 80 debug1: Remote connections from LOCALHOST:3301 forwarded to local address localhost:4242 debug3: send packet: type 80 debug1: Remote connections from LOCALHOST:3304 forwarded to local address 127.0.0.1:4242 debug3: send packet: type 80 debug1: ssh_init_forwarding: expecting replies for 5 forwards debug1: channel 0: new session [client-session] (inactive timeout: 0) debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug3: send packet: type 90 debug1: Requesting no-more-sessions@xxxxxxxxxxx debug3: send packet: type 80 debug1: Entering interactive session. debug1: pledge: network debug3: client_repledge: enter debug3: receive packet: type 80 debug1: client_input_global_request: rtype hostkeys-00@xxxxxxxxxxx want_reply 0 debug3: receive packet: type 4 debug1: Remote: /home/dbelyavs/work/upstream/openssh-portable/regress/authorized_keys_dbelyavs:1: key options: agent-forwarding port-forwarding pty user-rc x11-forwarding debug3: receive packet: type 4 debug1: Remote: /home/dbelyavs/work/upstream/openssh-portable/regress/authorized_keys_dbelyavs:1: key options: agent-forwarding port-forwarding pty user-rc x11-forwarding debug3: receive packet: type 81 debug1: remote forward success for: listen 3301, connect 127.0.0.1:4242 debug2: forwarding_success: 4 expected forwarding replies remaining debug3: receive packet: type 81 debug1: remote forward success for: listen 3302, connect 127.0.0.1:4242 debug2: forwarding_success: 3 expected forwarding replies remaining debug3: receive packet: type 81 debug1: remote forward success for: listen 3303, connect 127.0.0.1:4242 debug2: forwarding_success: 2 expected forwarding replies remaining debug3: receive packet: type 81 debug1: remote forward success for: listen 3301, connect localhost:4242 debug2: forwarding_success: 1 expected forwarding replies remaining debug3: receive packet: type 81 debug1: remote forward success for: listen 3304, connect 127.0.0.1:4242 debug1: forwarding_success: all expected forwarding replies received debug3: receive packet: type 91 ================ so the second forwarding succeeds. I have no ideas how to debug it further, so any help is much appropriate!
