[LFTP] This gets me crazy...

Sad_user · 04-30-2015, 03:23 AM

Hello fellow forum users.

I got some serious trouble with lftp.

This is what I am doing (copy paste from my terminal without modification) :

Code:

[root@s-starbatch-01 20150429]# ls
Ext_entretien_chaudiere_active_CRM_290415.csv  Ext_entretien_chaudiere_active_CRM.csv
[root@s-starbatch-01 20150429]# lftp -p 990 -u user,password ftp.ds-services.fr -e "set ssl:verify-certificate no; set ftp:ssl-allow yes; set ftp:ssl-auth TLS; cd upload; put Ext_entretien_chaudiere_active_CRM.csv;quit;"
cd ok, cwd=/upload
put: Access failed: 550 SSL/TLS required on the data channel (Ext_entretien_chaudiere_active_CRM.csv)

=> Ok I got an error because the data isn't encrypted with the put command, strange in my opinion, since the option to cypher the data is in the -e command.

Then I do this (which is exactly the same, just in 2 parts) :

Code:

[root@s-starbatch-01 20150429]# lftp -p 990 -u user,password ftp.ds-services.fr -e "set ssl:verify-certificate no; set ftp:ssl-allow yes; set ftp:ssl-auth TLS; cd upload;"
cd ok, cwd=/upload
lftp proxiservedocs@ftp.ds-services.fr:/upload> ls
lftp proxiservedocs@ftp.ds-services.fr:/upload> put Ext_entretien_chaudiere_active_CRM.csv;
1198 bytes transferred
lftp proxiservedocs@ftp.ds-services.fr:/upload> ls
-rw-r--r--   1 proxiservedocs userftp      1198 Apr 29 01:47 Ext_entretien_chaudiere_active_CRM.csv
lftp proxiservedocs@ftp.ds-services.fr:/upload>

Why is it working like this ?!

Since I'm trying to upload the file with a script, I really need it to be written on a single line. Any idea what I should do ?

And no I can't add those options in the lftp.conf file, I'm using lftp for different kind of stuff.

Thanks in advance for any help !

lftp is defaulting to ftp (non-encrypted) behavior for the initial connections because you have not given it proper instruction. Your script specifies the encryption after the connection, but the server is requiring it earlier. You must either provide a URL that specifies the encrypted protocol (not just a hostname), or provide a command option to lock in the protocol.

My preference, use the URL, Something like sftp://ftp.ds-services.fr might work. In this case it looks like ftps://ftp.ds-services.fr may work if the first option does not, but I have not tested either against this host.

I hope that this helps.

Hello,

Thanks for the reply. That could have been an option yes, sadly the ftp requires explicit TLS so the correct way is either ftp://ftp.ds-services.fr or ftp.ds-services.fr (since ftp is default as you said).

If I use ftps://ftp.ds-services.fr it requires implicit TLS which doesn't work for this ftp, and sftp:// wouldn't work at all of course because thats ssh.

Still searching, thanks for the help though, I feel less lonely.

Hmmm.

try this, do not use the -e option, instead use 'here' document redirection and stack the commands that way.
Something like

Code:

lftp -u user,pass p 21 ftp://ftp.thoseguys.fr <<END
set ssl:verify-certificate no 
set ftp:ssl-allow yes 
set ftp:ssl-auth TLS 

cd upload 
put Ext_entretien_chaudiere_active_CRM.csv
ls

quit

END

and see how that works.

Have you solved your problem? If so, how?
