I'd run strace on it. When I do strace -f ssh -vv -4 -2 -l joostje muso.komputilo.org 2>strace.txt then I see in strace.txt: [...] write(2, "debug2: service_accept: ssh-user"..., 38debug2: service_accept: ssh-userauth ) = 38 write(2, "debug1: SSH2_MSG_SERVICE_ACCEPT "..., 42debug1: SSH2_MSG_SERVICE_ACCEPT received ) = 42 write(2, "debug2: key: /home/joostje/.ssh/"..., 48debug2: key: /home/joostje/.ssh/id_rsa ((nil)) ) = 48 write(2, "debug2: key: /home/joostje/.ssh/"..., 51debug2: key: /home/joostje/.ssh/id_dsa (0x55dff0) ) = 51 write(3, "o\243\302\260\251\5\264\215o\'}3N\341\354\225\'\215\213"..., 64) = 64 select(4, [3], NULL, NULL, NULL) = 1 (in [3]) read(3, "d\265\232\322\'\v\215Md\370.t\2511\353\274\267G\212L\302"..., 8192) = 64 write(2, "debug1: Authentications that can"..., 63debug1: Authentications that can continue: publickey,password ) = 63 [...] In other words, my ssh writes two more debug statements right after the last debug statements you see, without any system calls in between. So, basically, it seems like it is 'impossible' for ssh to hang just at that point... Would be interesting to see the strace output of your ssh. After that it starts to write to fd 3, witch seems to be the communication socket to the SSH server.
