Complex password with special characters

2015-10-15 20:59

Hello all

I am trying to connect to a sFTP site and could not understand why I can connect without any problems using the GUI but the script failed. After much research and repeated trials, I cannot get this darn password to work in the script. The password is Vc%]=NBWX%85!@y@
I tried Vc%25]=NBWX%2585!@y@ (using the UTF-8 code) for %. No success, I then added %40 for the at sign, no success, I also adding the %21 for the ! (exclamation mark) no success

Any help would be appreciated.

Thanks

This works: Vc%25%5D%3DNBWX%2585%21%40y%40

Use Generate URL command next time:

Using username "username".
Authenticating with pre-entered password.
Access denied.
Connection has been unexpectedly closed. Server sent command exit status 0.
Authentication log (see session log for details):
Using username "username".
Access denied.

Authentication failed.

This is the script I am using

open sftp://username:Vc%25%5D%3DNBWX%2585%21%40y%40@mysftp.com -hostkey="ssh-rsa 2048 f5:d9:20:a4:4b:45:62:7d:0c:0b:5d:d0:6e:b6:2f:22"

Then your password is not Vc%]=NBWX%85!@y@.

Enable password logging in GUI and inspect the log file to see an exact password that is used.

This is the same issue that I'm having. I was able to log in directly to WinSCP. However, I used the generate URL with password and username and I get the same error message.

The password logging is not enabled. Also post a script log file for comparison (use /loglevel=* to enable password logging).

The double % (percent sign) is needed in batch files only. No one ever mentioned a batch file in this topic.
See https://winscp.net/eng/docs/faq_batch_file#percent
