problem with access remote server without password #11

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello! I'm using your framework to remote server grep. For example, I'm using 
next code:
             profile = ProfileBuilder.newBuilder()
                    .name("Max")
                    .filePath(serverPath)
                    .onRemotehost(host.getHost())
                    .credentials(login, pass)
                    .build();
             grep(constantExpression(id), on(profile));

and all working good. 
The problem appear, when I need to access the server, which has access through 
login WITHOUT password. I'm using:

            Profile profile = new Profile("Max", serverPath);
            ServerDetails serverDetails = new ServerDetails(host);
            serverDetails.setUser(login);
            serverDetails.setPasswordRequired(false);
            profile.setServerDetails(serverDetails);
         grep(constantExpression(id), on(profile));

But after grep I've got the next error:

ERROR [2013-12-11 10:36:09,902]

is this something you can workaround by using userAuthPrivateKeyLocation ? 
Example:
Profile remoteProfileWithPublicKey = ProfileBuilder.newBuilder()
                                     .name("Another remote server log")
                                     .filePath("/path/to/file/filename.txt")
                                     .onRemotehost("172.x.x.x")
                                     .userAuthPrivateKeyLocation("/home/user/.ssh/id_dsa")
                                     .withUser("user")
                                     .build();

But I'm sure, there're no problems with my permission to server - I can get 
into server by console

Code I'm using:

        Profile profile = ProfileBuilder.newBuilder()
                .name("Another")
                .filePath("/opt/eantifraud-processor/log/log.log")
                .onRemotehost("remote.host")                               //I tried IP of host too
                .userAuthPrivateKeyLocation("/home/user/.ssh/id_rsa")
                .withUser("user")
                .build();

        grep(constantExpression(myId), on(profile));

Did you generated a pair of authentication keys?
see http://www.linuxproblem.org/art_9.html
If you have a AuthPrivateKeyLocation you should point to your specific id_rsa, 
the code you are using is using the same as the grep4j example 
/home/user/.ssh/id_rsa which i doubt is your correct location.

May be too late to come to this page.. This is the same issue I had faced with 
remote access without requiring a password or "sudo". The solution explained in 
http://www.linuxproblem.org/art_9.html will resolve the issue. Only thing you 
need to do is to specify a correct RSA private key location.

Grep4j correctly returns the results after that.
