When I try to lớn SSH into my cluster, there are two stages. So I have to lớn enter the password twice to lớn go to lớn my trang chủ directory using SSH in a Linux terminal or PuTTY.

But when I try to lớn use WinSCP, I get these errors:

Trying SFTP:

Cannot initialize SFTP protocol. Is the host running a SFTP server?

Trying SCP:

Error skipping startup message. Your shell is probably incompatible with the application (BASH is recommended).

How can I bypass this problem?

I believe it will resolve your issue

Most of the time it happened due to lớn the password expired . So you need to lớn make vì thế right click on that WinSCP user's and you'll find the option Open in PUTTY, PFA.

After PuTTY opened, Enter Your Current Password and it will ask to lớn reset New Password. And you will get access successfully, its worked for má :)

Actually, this error may be misleading in some cases. Assuming that SSH works (which is the case for you), it could simply be the fact that your bash is outputting some text which breaks SCP.

Once you SSH into your system, is there some text printed? (Example some welcome text). If that is the case, you could put a test in your ~/.bashrc (or whatever script is first loaded, lượt thích ~/.bash_profile on some systems) and kiểm tra if the shell is interactive or not. If not interactive, vì thế not print anything. You can use this to lớn skip printing anything (put this at the beginning of .bashrc) :

#Detect if in SCP
if [ -z "$PS1" ]; then
    return
fi

Solution: Provide the path of the SFTP server, as shown in a screenshot:

For general information, read documentation on the error message Cannot initialize SFTP protocol. Is the host running a SFTP server?

Though for your particular case, the problem is likely caused by the server not being able to lớn talk to lớn WinSCP for exchange of the second password. What is the second password for? The sudo? Or an SSH tunnel to lớn a second "stage" (whatever that is)?

For sudo/su, refer to lớn the WinSCP FAQ How vì thế I change user after login (e.g. su root)?

For tunneling, refer to lớn the tunneling documentation.

I'm aware that this is bit vague answer, but ví is your question. If you describe, what the two passwords are for, and if you share a session log tệp tin, you might get better answers.

I was having the same issue but I just switched the File Protocol from SFTP to lớn regular FTP and it worked.

These are different types of error that we get on WINSCP-

  1. WARNING: Your password has expired OR
  2. Cannot initialize SFTP protocol. Is the host running an SFTP server? OR
  3. Authentication Failed.

Try the below mentioned methods to lớn resolve the above errors:

Change File Protocol from SFTP to lớn SCP

As the error itself says there is a problem with the SFTP protocol ví try changing the File Protocol first. Explained below:

Click on edit -> choose SCP from the dropdown thực đơn given for File Protocol -> click on save and then login

Reset the Password using PuTTY

If still the problem is not resolved then finally you have the last option to lớn reset the password using PuTTY.

PFB Steps -

  1. Right click on the current site/server/user of WINSCP -> select "Open in PuTTY" option OR Select the current site/server/user of WINSCP -> press Ctrl+P

  2. When PuTTY is opened, enter your password and then it will ask you to lớn enter a new password.

Note: Password will not be visible to lớn you, ví enter them carefully.

You can then use the new password to lớn login. It will work for sure.
