WinSCP treats normal file as directory when using SFTP

2009-06-06 22:53

Hello,

I have a problem while using WinSCP to access remote file with SFTP(V2) protocol.
The login process is trouble-free. But if I double-click a normal file on remote side, e.g. "erlang.pdf". WinSCP seems to treat this file as a directory, and wants to go into. This behaviour will centainly cause an error with code 2 -- No such file or directory.

If I right click the file, <Open> and <Edit> command are not in bold, which means not a default action. If one of them is selected manually, the behavior is totally normal.

If I connect the server with SCP, the problem is gone. (But SCP protocol spends more time on login, so I prefer SFTP.)

There are 4 servers in my local network. This issue happens on two of them. The other two have no such problem.

So I think it's strange, but don't know who is doing things wrong, server or client? If it's client, I think the problem is probably not in network level but GUI level.

I'm using WinSCP 4.2.1 (Build 428).
This problem appears under XP(SP3 x86), Vista(Ultimate x64), Win7(RC 7100 x86).

Below is the log file created by level "normal".

Any suggestion is welcome!

Best wishes
Moudy

Re: WinSCP treats normal file as directory when using SFTP

2009-06-08

The problem is that your server supports only version 2 of the SFTP protocol. With this version WinSCP is not able to tell if file is regular file or symlink to directory. As symlinks to directories are very common, WinSCP always tries to open file as directory when double-clicked. This is discussed in documentation.
Note that SFTP-2 is very obsolete and rare. Actually I've never seen myself a server that uses it.

But SCP protocol spends more time on login, so I prefer SFTP.

Try to disable Clear national variables, Clear aliases and Lookup user groups on SCP tab of login dialog.

Thanks for your explanation and suggestion. Now the SCP login connect really fast.

BTW the two servers are gateways to other sub networks. Our admin applied the oldest configurations on it for maximal stability. :(
