Suggested fix:
else {
// Format: \hostname\share
slash_ptr = strchr(share + 2, '');
strcpy(tango_connection_ptr->share, slash_ptr+1);
}

Is there a way to browse all the available shares on a server ?

Thanks
Marco

How can I upload a image file ?
There is only a example for upload a simple small text content to a file.

Hi Ben,
Thanks. Will try to get a Windows 7 VM and have a look at the issue. As suspected, it has to do with the authentication-method supported with Win7.
I will have to add the NTLM2 authentication method (http://ubiqx.org/cifs/SMB.html 2.8.5 NTLM Version 2)

Cheers,
Daniel

Dear sir,
I have the same problem as #5, I deeply hope the NTLM2 authentication method, Can you help me?

Thanks a lot!

Hi.tan

inside _tango_TRANS2_FIND_FIRST2, if the response is rather large, the server returns only part of the data.
so the check:
if (resp_total_data_count != resp_data_count) {
will fail, since (resp_total_data_count > resp_data_count)

any suggestions on how to fix?

I am a beginner IOS. I am making a SMB client to connect SMB sever. I used tango (https://github.com/38leinaD/tango). If I used Mac : Go -> connect to server.. -> smb://192.168.1.8 . connect normally! but if I use tangoLogin, in Share 's editText: address is "\192.168.1.8\Movies ", Tango Testapp will notice :" Unble to login" ( i filled user and password exactly ). i don't understand.

When i am trying to connect i am getting below error as below

tango_connect(): Failed to connect(); Operation timed out.

please help!!

using inet_pton doesn't seem to be the right approach in tango_connect.
Instead of:
int sin_addr_set = inet_pton(AF_INET, hostname, &(sock_addr.sin_addr));

The following could be used:

static struct in_addr addressForHost(const char* hn)
{
struct hostent *hostinfo;
struct in_addr inaddr;
inaddr.s_addr = inet_addr(hn);

if(INADDR_NONE == inaddr.s_addr) {
    hostinfo = gethostbyname(hn);
    if(NULL == hostinfo) {
        inaddr.s_addr = INADDR_NONE;
        return inaddr;
    }

    inaddr.s_addr = *((in_addr_t *)hostinfo->h_addr_list[0]);
}

return inaddr;

}

sock_addr.sin_addr = addressForHost(hostname);
int sin_addr_set = sock_addr.sin_addr.s_addr != INADDR_NONE;

Hi I hit this weird error on my linux server(using samba service of course) that I can access some directories under the same directory while others gave me the error message, "_tango_evaluate_response_header(): NT_STATUS Level is 0003 with value 000d." Can you take a look ? Thanks!

Hi,

I wonder, if anybody can help me on this issue: Connecting to a file share on Windows XP works alright, but a SAMBA share fails. Password encryption on the samba server is switched on. The server log states invalid credentials.

Thanks for any help in advance!

Hi Daniel,

I'm very interested and curious with your lib. Thank you for the lib.

The issue I'm facing is I cannot log into a XP machine. I got the same error code as the issue #5. . It looks like the lib supported XP already but I don't know why it doesn't work for me. I tested the lib with an iPhone emulator.

Do you have any idea to solve this problem?

Thanks again for the good lib.

I am getting error when I am trying to get shared folder of windows XP with iphone app.
Please help.

Great work on this. I've run into a bit of a problem that I think some of the other posts have touched upon. Sometimes when connecting or accessing a folder, I'll run into the "_tango_evaluate_response_header(): NT_STATUS Level is 0003 with value 000d." error and the tangoFSFolderViewController will load with 0 rows. If I hit the "Back" button and try to navigate to another folder or the SAME folder, sometimes, the connection randomly goes through and the contents of a folder will show up correctly, but more often than not, a new tangoFSFolderViewController shows up with 0 rows. This leads me to believe there's some sort of latency or race issue going on. I notice that whenever the connection does not go through, smb_response's size variable always returns with a size of 35 and none of the "Connection problem" error handling messages of _tango_send or _tango_receive are hit. The call of _tango_TRANS2_FIND_FIRST2 bails out here:

/**
 * 3. Evaluate Response
 */
if (!_tango_evaluate_response_header(connection, smb)) {
        goto bailout;
    }

Does the connection to SMBs work pretty consistently on XP? I haven't tried it out yet. Maybe OSX is the problem?I'm running this on OSX 10.6 (Snow Leopard) with Windows File Sharing enabled. Appreciate any tips you can throw my way. Thanks.

device: iPad2: iOS 5.0.1
desktop: Macbook Pro: Mac OS X 10.7.2

I tried to download and run your sample app on iOS 5 and it wouldn't display properly. However, I put your library and obj c wrapper classes into a test project and I kept getting this error and output:

2011-12-11 14:10:48.888 TEST_Tango[4243:707] pressed
_tango_send(): Bytes to send (including nbt-header!): 51
_tango_send(): Sent 51 bytes.
_tango_send_and_receive(): Timeout during recv(): No such file or directory

I do have file sharing enabled on my desktop. For the share input field I have tried:
[host name].local[share folder]
[host name].home[share folder]
[host name].local
[host name].home\

I am not sure if this is something I am doing wrong, but it never seems to retrieve any fileInfo on the first try using listDirectory. I end up having to insert it in a while loop and keep calling that function until something is retrieved. But even then there's often many files missing, others don't have any names.
Whats wrong with that?

Please help..

what can i set in share, username & password field.
means my server ftp details or my pc ip address & pc login password.

Please suggest...

I fixed half of it by using unicode instead of ASCII and setting the flag to unicode in _tango_TRANS2_FIND_FIRST2 and now the request goes through without error when watching it on the sniffer. However since the response is unicode I need to modify the response parsing.

I've tried connecting share drive on Windows 7 or Windows Server 2008 R2 and failed with the error message "Error. Unable to login" on the iphone.
