Hello. I am creating tunnel to my home machine from my work machine this way (rknight.homelinux.net is my home machine): ssh -vvv rknight.homelinux.net -L 0.0.0.0:5222:rknight.homelinux.net:5222 -N When I use this tunnel (doing HTTP query) you can see this in console (for each query): ---- debug1: Connection to port 5222 forwarding to rknight.homelinux.net port 5222 requested. debug2: fd 5 setting TCP_NODELAY debug2: fd 5 setting O_NONBLOCK debug3: fd 5 is O_NONBLOCK debug1: channel 1: new [direct-tcpip] debug2: channel 1: open confirm rwindow 2097152 rmax 32768 debug2: channel 1: rcvd eof debug2: channel 1: output open -> drain debug2: channel 1: obuf empty debug2: channel 1: close_write debug2: channel 1: output drain -> closed debug2: channel 1: read<=0 rfd 5 len 0 debug2: channel 1: read failed debug2: channel 1: close_read debug2: channel 1: input open -> drain debug2: channel 1: ibuf empty debug2: channel 1: send eof debug2: channel 1: input drain -> closed debug2: channel 1: send close debug3: channel 1: will not send data after close debug2: channel 1: rcvd close debug3: channel 1: will not send data after close debug2: channel 1: is dead debug2: channel 1: garbage collecting debug1: channel 1: free: direct-tcpip: listening port 5222 for rknight.homelinux.net port 5222, connect from 127.0.0.1 port 54212, nchannels 2 debug3: channel 1: status: The following connections are open: #1 direct-tcpip: listening port 5222 for rknight.homelinux.net port 5222, connect from 127.0.0.1 port 54212 (t4 r0 i3/0 o3/0 fd 5/5 cfd -1) ---- debug3: channel 1: close_fds r 5 w 5 e -1 c -1 But after some time this happens: ---- debug1: channel 8: new [direct-tcpip] debug2: channel 3: open confirm rwindow 2097152 rmax 32768 debug2: channel 1: open confirm rwindow 2097152 rmax 32768 debug2: channel 4: open confirm rwindow 2097152 rmax 32768 debug2: channel 5: open confirm rwindow 2097152 rmax 32768 debug2: channel 6: open confirm rwindow 2097152 rmax 32768 debug2: channel 7: open confirm rwindow 2097152 rmax 32768 debug2: channel 8: open confirm rwindow 2097152 rmax 32768 debug2: channel 2: read<=0 rfd 6 len 0 debug2: channel 2: read failed debug2: channel 2: close_read debug2: channel 2: input open -> drain debug2: channel 2: ibuf empty debug2: channel 2: send eof debug2: channel 2: input drain -> closed debug2: channel 2: rcvd eof debug2: channel 2: output open -> drain debug2: channel 2: obuf empty debug2: channel 2: close_write debug2: channel 2: output drain -> closed debug2: channel 3: rcvd eof debug2: channel 3: output open -> drain debug2: channel 2: send close debug3: channel 2: will not send data after close debug2: channel 3: obuf empty debug2: channel 3: close_write debug2: channel 3: output drain -> closed debug2: channel 3: read<=0 rfd 7 len 0 debug2: channel 3: read failed debug2: channel 3: close_read debug2: channel 3: input open -> drain debug3: channel 2: will not send data after close debug2: channel 3: ibuf empty debug2: channel 3: send eof debug2: channel 3: input drain -> closed debug2: channel 3: send close debug3: channel 2: will not send data after close debug3: channel 3: will not send data after close ---- And tunnel freezes.
