remote disconnect
Richard Bonomo	remote disconnect	Sep 02 2010 19:54

Hello! When I log in from one of our Windows systems using PuTTY, the ssh server works OK, at least allowing the log-in to go through. When I attempt to log in from a Mac using the native ssh client, I simply get a "remote disconnect" message with no request for a password first being issued. Here is an extract of the log: 560 : 592 2010- 9- 2 12:19:11 549 : 0: KTS connected to <windows XP workstation PuTTY>:3360 5248 : 3928 2010- 9- 2 12:19:11 799 : 0: session.exe started 5248 : 3928 2010- 9- 2 12:19:11 893 : 0: connected to <windows XP workstation PuTTY>:3360 5248 : 3928 2010- 9- 2 12:19:12 908 : 0: ssh initialized 5248 : 3928 2010- 9- 2 12:19:21 2 : 0: login accepted: [ <my user name> ] 5248 : 3272 2010- 9- 2 12:27:55 846 : 0: shell is dead 5248 : 3272 2010- 9- 2 12:27:56 846 : 0: shutdown 5248 : 5820 2010- 9- 2 12:27:56 846 : 0: session.exe end 560 : 592 2010- 9- 2 12:31: 7 80 : 0: KTS connected to <Mac OS 10 workstation native ssh>:51311 3876 : 2192 2010- 9- 2 12:31: 7 190 : 0: session.exe started 3876 : 2192 2010- 9- 2 12:31: 7 783 : 0: connected to <Mac OS 10 workstation native ssh>:51311 3876 : 2192 2010- 9- 2 12:31: 8 783 : 0: ssh initialized 3876 : 2192 2010- 9- 2 12:31: 9 627 : 0: doing publickey authentication - unknown publickey 3876 : 2192 2010- 9- 2 12:31: 9 674 : 0: login refused: [ <my user name> ] - Logon failure: unknown user name or bad password. 3876 : 2192 2010- 9- 2 12:31: 9 674 : 0: can't read login 3876 : 4468 2010- 9- 2 12:31: 9 690 : 0: session.exe end 560 : 592 2010- 9- 2 12:31:45 158 : 0: KTS connected to <Mac OS 10 workstation native ssh>:51313 5172 : 4944 2010- 9- 2 12:31:45 283 : 0: session.exe started 5172 : 4944 2010- 9- 2 12:31:45 362 : 0: connected to <Mac OS 10 workstation native ssh>:51313 5172 : 4944 2010- 9- 2 12:31:45 877 : 0: ssh initialized 5172 : 4944 2010- 9- 2 12:31:46 549 : 0: doing publickey authentication - unknown publickey 5172 : 4944 2010- 9- 2 12:31:46 549 : 0: login refused: [ <my user name> ] - Logon failure: unknown user name or bad password. 5172 : 4944 2010- 9- 2 12:31:46 549 : 0: can't read login 5172 : 3192 2010- 9- 2 12:31:46 565 : 0: session.exe end 560 : 592 2010- 9- 2 12:31:53 565 : 0: KTS connected to <Mac OS 10 workstation native ssh>:51314 5120 : 4188 2010- 9- 2 12:31:53 674 : 0: session.exe started 5120 : 4188 2010- 9- 2 12:31:53 752 : 0: connected to <Mac OS 10 workstation native ssh>:51314 5120 : 4188 2010- 9- 2 12:31:53 768 : 0: ssh initialized 5120 : 4188 2010- 9- 2 12:31:54 377 : 0: can't read login 5120 : 4188 2010- 9- 2 12:31:54 377 : 0: ssh info: Error reading client's SSH identifier string: No data was read because the remote system closed the connection (recv() == 0) 5120 : 5548 2010- 9- 2 12:31:54 377 : 0: session.exe end 560 : 592 2010- 9- 2 12:32: 6 252 : 0: KTS connected to <Mac OS 10 workstation native ssh>:51315 4796 : 5996 2010- 9- 2 12:32: 6 362 : 0: session.exe started 4796 : 5996 2010- 9- 2 12:32: 6 440 : 0: connected to <Mac OS 10 workstation native ssh>:51315 4796 : 5996 2010- 9- 2 12:32: 6 455 : 0: ssh initialized 4796 : 5996 2010- 9- 2 12:32: 7 643 : 0: doing publickey authentication - unknown publickey 4796 : 5996 2010- 9- 2 12:32: 7 658 : 0: login refused: [ <my user name> ] - Logon failure: unknown user name or bad password. 4796 : 5996 2010- 9- 2 12:32: 7 658 : 0: can't read login 4796 : 5872 2010- 9- 2 12:32: 7 658 : 0: session.exe end 560 : 592 2010- 9- 2 14:24:54 362 : 0: KTS connected to <Mac OS 10 workstation native ssh>:51492 4856 : 6040 2010- 9- 2 14:24:54 487 : 0: session.exe started 4856 : 6040 2010- 9- 2 14:24:54 565 : 0: connected to <Mac OS 10 workstation native ssh>:51492 4856 : 6040 2010- 9- 2 14:24:55 96 : 0: ssh initialized 4856 : 6040 2010- 9- 2 14:24:55 768 : 0: doing publickey authentication - unknown publickey 4856 : 6040 2010- 9- 2 14:24:55 783 : 0: login refused: [ <my user name> ] - Logon failure: unknown user name or bad password. 4856 : 6040 2010- 9- 2 14:24:55 783 : 0: can't read login 4856 : 3936 2010- 9- 2 14:24:55 799 : 0: session.exe end Please note: despite what the log says, not user name or password is even requested.

It looks like your Mac clients by default tries to log you in with your public key and when it fails KTS gets confused. You can try to force your client to use only "password" authentication by running it with somthing like this ssh -o PreferredAuthentications=password -l username hostname Kroum

OK, that seems to work. Thanks!
