Putty works, winscp does not.

English Network/Internet

Hi,

I have a windows laptop which I seldom use, but reading the recent thread
about “Putty: Server refused our key” I want to replicate it - but my
problem is that although putty connects without problems (with password)
winscp does not. It claims “Host is not communicating for more than 15
seconds. Still waiting.”

But that is not true, I see the attempt in the Linux machine:


> <4.6> 2012-06-02 02:08:35 Telcontar sshd 20033 - -  Accepted keyboard-interactive/pam for cer from 192.168.1.33 port 49252 ssh2
> <4.6> 2012-06-02 02:08:35 Telcontar sshd 20044 - -  subsystem request for sftp by user cer

I’m using winscp437 and oS 11.4

In the windows side, the short log, copied by hand, says:

Searching for host
connecting to host
Authenticating…
using username “cer”
Authenticated
Starting the session…
reading remote directory…

and here it gets stuck, with the above claim of no response. In the host I
see no activity reading directories.

Very strange. I’m a pretty heavy winscp user and I’ve never seen this before. Are you using the standalone version or the one that you have to install ?

The installable version. I have just upgraded to the beta 507, same result.

I managed to get a log on the windows side.

I thought you could try the standalone version because I always use that but anyway I don’t think that’s the problem. Honestly I’ve got no idea what might be the reason for this not working.

No difference, except that in mine data doesn’t come in :frowning:

Is your Windows firewall up or down? It should not affect, but it is the
only thing I haven’t tried (I’m afraid of lowering it down, it is on wifi).

Windows firewall is up. You can enable logging in the windows firewall quite similar to the way you can do this in YaST :slight_smile: or try with firewall disabled but I doubt that’s the problem.
