I mean you can hardly make the ExecuteCommand work on the VMS in general. Why do you want to call the ls command? Use the ListDirectory.

On VMS :
> show symbol pwd
PWD == "SHOW DEFAULT"

"symbol" is similar to "alias" on linux.

Thanks for the links!

I tried to write out the session.HomePath after session.Open:
log.wrln("home-path: >" + session.HomePath+"<");
home-path: >/disk$data_4/user/cba***<

it worked so the winscp can use the VMS.

I tried the command line too :
"C:\Program Files\WinSCP\winscp.com" /command "open sftp://cba***:haf***@5.175.***.*** -hostkey=""*"" -rawsettings KEX=""dh-group1-sha1,dh-group14-sha1,dh-gex-sha1,rsa,WARN"" " "pwd" "exit"
and
"C:\Program Files\WinSCP\winscp.com" /command "open sftp://cba***:haf***@5.175.***.*** -hostkey=""*"" -rawsettings KEX=""dh-group1-sha1,dh-group14-sha1,dh-gex-sha1,rsa,WARN"" " "ls" "exit"
It worked too. I can see the ls's output.

I tried other command to run in C# :
dumpCommand = "ls";
but the error is same: "Server unexpectedly closed network connection."

Can you help me with other links?
Thanks in advance!

The ExecuteCommand method tries to open shell and execute the pwd command there, what will hardly work on VMS.
See https://winscp.net/eng/docs/remote_command

Read the Session.HomePath instead.

Hi Martin, hi Winscp-Team,


in my report "***" mean "I remmoved a part of string".
I use "win7", "Open-VMS 8.3", "winscp v5.9", "VisualStudio 2015 Express"

So when I run the follow command in cmd.exe:

"C:\Program Files\WinSCP\winscp.com" /command "open sftp://cba***:haf***@5.175.***.*** -hostkey=""*"" -rawsettings KEX=""dh-group1-sha1,dh-group14-sha1,dh-gex-sha1,rsa,WARN"" " "pwd" "exit" /log="C:\Users\***\Desktop\winscp_bug\batch.log" /loglevel=2

then it is workd. OK :)
("dh-group1-sha1" must be used for VMS )
I attached thw log from batch-run too.(batch.log)

But when I run my "C#_code.cs" (it is attached)
I get this output with error :

dumpCommand: pwd
output :
ErrorOutput:
IsSuccess : False
ExitCode : 0
WinSCP.SessionRemoteException: Server unexpectedly closed network connection.
Authentication log (see session log for details):
Using username "cba***".
Authentication failed.
Server unexpectedly closed network connection.
Authentication log (see session log for details):
Using username "cba***".
Authentication failed.

The "session.DebugLogPath" and "session.SessionLogPath" are attached too. (c#_code.deblog, c#_code.log)

IP, loginname, password, winscp version are same.
When I mixd run the "batch" and "c#_code" i have the same error for "c#_code" and the batch is always error-free.

I read the forum and the documentation but i din'nt find explanation or i am not enought adept.
I hope you can help for me.
Thanks in advance!
