Re: [lftp] lftp 4.6.1 - issue with close command
Thank you, this works close && open "" May I suggest as a future enhancement to add an option to the close command to actually do a disconnect, ie invalidate the last open ? Regards.

I expected this to fail. It's correct behaviour. "close" command closes connections to the server, but the server is still selected for communication.

You can use one on these: set cmd:fail-exit yes or open ... || exit -- Alexander. ___ lftp mailing list lftp@uniyar.ac.ru http://univ.uniyar.ac.ru/mailman/listinfo/lftp
Re: [lftp] lftp 4.6.1 - issue with close command
I am using SFTP (SSH) Per a suggestion on the list, I tried the following, but same behavior: set ftp:web-mode true open -u "username,password" -p 22 sftp://hostname/ put /tmp/test.bin <- works close put /tmp/test.bin <- still connects and upload a file Certainly an unwanted behavior in the environment I'm working in. Imagine the following scenario: open -u "username1,password1" -p 22 sftp://site1/ <- works mput /tmp/site1.* <- works close open -u "username2,password2" -p 22 sftp://site2/ -< fails mput /tmp/site2.* <- since the lat open failed, still connects to site 1 and upload a file, hence high risk. Interested on how to resolve this, ie how to safely open and close multiple connections in the same lftp script. Thanks !
