method to check if ftp server is available?

2017-05-02 22:29

Hello.
Is there a way to check if ftp server is available before sending ftp command to it?
Session.Opened member does not provide server status.
I tried stopping ftp server between requests, and it seems like there is no way to detect if it is available.
The way I see it is to create another instance of the Session object and try to open it...
If I stop server with live connection, component hangs at this method "ElementLogReader.Read(LogReadFlags flags)" or this one "SessionElementLogReader.Read(LogReadFlags flags)"...
Any suggestions?
thank you.

It does not hang. It should timeout eventually.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

thank you.
The point was to check if internet, server, and network are available before sending command or creating connection. i have solved the problem by writing my own code.
thank you anyway.
