Hi Mike,
the problem was really that!
From 'puttygen' I just did 'save private key' as "C:/Utility/Putty/ssh_daemon/ssh_host_rsa_key" , which was not the openssh file key format.
Selecting "Conversion" for the private key the problem is over .
Thanks a lot for your help!!!
Cheers,
/Mario

Hi Mario,
I noticed that you had "Putty" in your dir path ("C:/Utility/Putty/ssh_daemon"). Is your private key a .ppk file? Putty on Windows uses a different file format for its keys than what the Erlang ssh library is expecting. From "PuTTY Key Generator", select "Conversions" -> "Export OpenSSH key" and save it as "C:/Utility/Putty/ssh_daemon/ssh_host_rsa_key".
Hope that helps,
Mike

Re: [erlang-bugs] Error on running
Erlang SSH server
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"} ]).
鈀{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.

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. ?
/Tony
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>
=ERROR REPORT==== 29-May-2014::17:44:58 ===

please report this to 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.
Regards,
/Mario
