Endless map loop
23-01-2004 15:44Hello,
I am trying to connect to a Unix server. Everything works fine until Winscp tries to get the folder structure. It starts reading in an infinite loop.
What could be the reason for this?

Re: Endless library loop
23-01-2004This may not mean an infinite loop. In SFTP, the client must issue SSH_FXP_READDIR several times until the server responds that there are no more files. So, if the list is very large, it may require tens of thousands (even hundreds) of requests. Does it help if you start in a different folder (see the Environment tab in the login dialog)?

None. Even if I specify the full path to the folder with only 2 files, it still seems to "mess around"

It looks like a bug on your server. Because when the record finishes, it should respond to SSH_FXP_STATUS with an EOF code, but continue to respond to SSH_FXP_NAME. Have you tried another SFTP client? Can I get a trial account on your server?

I haven't tried it elsewhere (this is the only SFTP client I use). But I can connect without problems with F-Secure-SSH version 5.3. Unfortunately, this server cannot be accessed offline.

Is F-Secure-SSH just an SSH terminal or an SFTP client? You canPSFTP from the Putty package? It's a command line client, just try to print the folder.

F-Secure-SSH works in both modes. Code: 3des-cbc-hmac-sha1.
I tried FFPTP from Putty. Server key fingerprint is installed. But when I try to connect I get:

Look for the host "myserver.intranet.ca"

We require version: SSH-2.0-PuTTY-Release-0.53b

The master keyprint is:
ssh-dss 1024 0f:e2:c6:1b:ae:e0:d7:51:61:73:1c:89:38:aa:65:06
The incoming packet was corrupted during decryption
Fatal: The incoming packet was corrupted during decryption
I checked this error message in Putty. The documentation says that:
Versions below 2.0.11 of the SSH server software from ssh.com incorrectly calculate session encryption keys. This issue can cause various error messages such as "The incoming packet was corrupted during decryption" or maybe even "Out of memory".
If this error is detected, PuTTY will calculate the encryption keys in the same way as the failed server, so communication is still possible. If this error is enabled when you are talking to the correct server, the communication will fail.
This is a SSH2 specific error.
Could that be the problem?

Try the latest development snapshot instead of the latest version 0.53b which is very old.
I will try to prepare a debug version of WinSCP to monitor what is happening on your server. I will contact you then.

Re: Endless library loop
28-01-2004I may have found the cause of the problem.
First, some details about the SFTP protocol:
Each request that the client (here WinSCP) issues to the server has an associated identifier (number). The server returns the same identifier in response to the request. The purpose of the identifier is to be used by the client to match the response to the original request (there may be multiple outstanding requests and the server may respond in a different order).
Typically, clients increment the ID with each request. So does WinSCP. But by my mistake it doesn't apply to later queries in the catalog. All requests are with the same ID.
I believe this is not against the SFTP spec as it does not prohibit reuse of the same identifier. However, this is clearly against common sense, so I will change it in the next version.
I think the same ID for all requests makes your server always respond with the same response (the first part of the directory list). And that leads to an endless loop.

It still repeats in a folder containing 2 files
28-01-2004 15:50Hello,
The change did not solve the problem. Could the cause be the SFTP protocol version being used (version 2). Which version does WinSCP support?

:-(
WinSCP should support all versions of SFTP (0 to 4). Unfortunately, I don't have an SFTP server that supports versions below 3 to test this myself. However, I know from the spec that reading the library only changed between version 3 and 4.
Okay, I'll try harder, I'll get back to you soon. In the meantime, try another SFTP client, e.gPSFTP(command line). Let me know if it works.
Thank you for your patience. I'd love to work that out!
