unable to connect to FTP using IP address

[Yared Melese]

Hello

Would you please let me know if I missed anything, I am using FTPClient and using IP address as a host but not able to connect

Here are my commands

using FTPClient

ftp_init()

ftp = FTP(host="192.168.251.200", implt=true, ssl=true, user="anonymous", pswd="")

binary(ftp)

file = download(ftp, "dataOnFTP.bin", "C:\Users\xyz\test.bin")

close(ftp)
ftp_cleanup()

when sending  " using FTPClient" there are bunch of warnings as shown below partially

WARNING: Base.String is deprecated, use AbstractString instead.
  likely near C:\Users\melese\.julia\v0.4\FTPClient\src\FTPC.jl:35
WARNING: Base.String is deprecated, use AbstractString instead.

..

.

.and at the end I am getting the following error

ERROR: Failed to connect. :: LibCURL error #7
 [inlined code] from C:\Users\melese\.julia\v0.4\FTPClient\src\FTPC.jl:138

Hi Yared,

The error you are getting is something LibCURL is erring on, as described here. https://curl.haxx.se/libcurl/c/libcurl-errors.html

If I try using curl with your settings, I get

~ $ curl -u anonymous '192.168.251.200/dataOnFTP.bin'
Enter host password for user 'anonymous':
curl: (7) Failed to connect to 192.168.251.200 port 80: Network is unreachable

The FTPClient.jl uses the same library as curl and if you could post how to get the file with curl, I might be able to better serve you.

Hi Samuel,

Thanks for your inputs

I am trying to connect to a file server with IP address and get the latest file with certain extension then process the data and save it on local drive, then delete the file from the server.

Sorry, I don't know how to get files from Curl, it seems it is mainly designed for Http

Thanks

No worries, can you show me how you get the file with another program?

[Yared Melese]

Hi Samuel,

Here is how it is done in matlab

% connect to ftp

f = ftp(host, username, password)

mget(f,'dataOnFTP.bin')

% read data from file

readData = fopen('dataOnFTP.bin', 'r', 'ieee-le')

%delete file from server

delete(f, 'dataOnFTP.bin');

 Here one thing not included is I would like to find the latest file from FTP server because there might be similar names with different suffix.

Thanks

Hi Samuel,

Would you please let me know if the information I provided is enough?

Thanks

Hi Yared

Sorry, I got side tracked by other things and forgot about this. 

Can you show what's in "host", "username", and "password"? Is it just "192.168.251.200","anonymous", and "" respectively?

I tried 

ftp('192.168.251.200', 'anonymous', '')

But got an error saying that I was unable to reach it. But that might make sense if I don't have access to it, is that the case here?

Other things that might help is that are you sure your ftp connection is over ssl? Is it implicit? Maybe playing around with `implt=true, ssl=true` in 

ftp = FTP(host="192.168.251.200", implt=true, ssl=true, user="anonymous", pswd="")

might work.

Hi Samuel,

Thanks

The following worked

ftp = FTP(host="192.168.255.69")

However, if I want the transfer to be in binary mode then it won't work

Thanks

Hi Yared,

Okay, since it worked with you and not me I won't be able to tests my solutions.

You don't specify that you want to download in binary when you make the connection. I'm not sure what version of FTPClient.jl you are using, but binary downloads did not work on the first version of FTPClient.jl.

If you have a correct version, you can do the following.

using FTPClient

ftp_init()

ftp = FTP(host="192.168.251.200")

file = download(ftp, "dataOnFTP.bin", "C:\Users\xyz\test.bin")

close(ftp)

ftp_cleanup()

Binary is longer a function in the latest version of FTPClient.jl and it is currently assumes that downloads are in binary. So there's no need to specify it.

Let me know if this does or doesn't work.

Hi Yared,

Hopefully my last reply worked for you.

If you have anymore questions about how to use FTPClient.jl or find other issues, you are more than welcome to make an issue here https://github.com/invenia/FTPClient.jl/issues 

I'll be more likely to see your problem there.

Cheers,

Sam
