[erlang-bugs] Error on running Erlang SSH server

[Mario Santoro]

Hi Tony,
you were right about the wrong tuple where I specified the system_dir.

Tried with the following:

>{ok, Sshd} = ssh:daemon(8988, [{auth_methods, "password"}, {user_passwords, [{"mario", "mariopasswd"}]}, {system_dir, "C:/Utility/Putty/ssh_daemon"} ]).
âZ{ok,<0.644.0>}

but at client connection:
>{ok, ConnectionRef} = ssh:connect("E7E4115BF83167", 8988, [{user, "mario"}, {password, "mariopasswd"}, {user_dir, "C:/Utility/Putty/public_key"}, {silently_accept_hosts, true}, {user_interaction, false} ], 5000).
** exception error: no match of right hand side value {error,"Internal error"}

I got the same error.

The host keys are installed in the specified paths.

Hi,
which ssh version are you running?

Hi Hans,
from the output of ssh:module_info()., I get:
¡­
{version,"4.9"},
{time,{2013,2,25,19,38,30}}
¡­


Thanks all so far for your help.

/Mario

Hi,
I¡¯m trying to run an SSH server in Erlang and test a <user/password> connection over SSH.
I¡¯ve generated an RSA keys pair (with NO passphrase) for the SSH system and put the private key into ¡°C:/Utility/Putty/ssh_daemon¡± directory,
while the user public_key is into ¡°C:/Utility/Putty/public_key¡± directory.
I¡¯m running both the server and the client on the same PC, into two different Erlang nodes.

The SSH server starts fine:
(node1@REDACTED)1> ssh:start().
ok
(node1@REDACTED)2> {ok, Sshd} = ssh:daemon(8988, [{auth_methods, "password"}, {user_passwords, [{"mario", "mariopasswd"},{system_dir, "C:/Utility/Putty/ssh_daemon"}]} ]).
{ok,<0.54.0>}

Could the problem be that {system_dir, "C:/Utility/Putty/ssh_daemon"}
is specified in the {user_passwords,..} list and not as a separate option. ?

but on receiving a connection from the client:
(node2@REDACTED)1> ssh:start().
ok
(node2@REDACTED)2> {ok, ConnectionRef} = ssh:connect("E7E4115BF83167", 8988, [{user, "mario"}, {password, "mariopasswd"}, {user_dir, "C:/Utility/Putty/public_key"}, {silently_accept_hosts, true}, {user_interaction, false} ], 5000).
** exception error: no match of right hand side value {error,"Internal error"}


the SSH server application is crashing with the following error:
(node1@REDACTED)3>

please report this to erlang-bugs@REDACTED<mailto:erlang-bugs@REDACTED>


This happens at each client connection attempt.
Could you please help me on this issue?

Thank you in advance for your help.
