To generate log file, enable logging, log in to your server and do the operation and only the operation that causes type 2 protocol error too many authentication failures the error. 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 may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log._________________Martin Prikryl jld3y [View user's profile] Joined: 2013-05-16 Posts: 2 Location: jld3y Posted: 2013-05-16 14:25 [Reply with quote] I have emailed the log directly to Martin. martin [View user's profile] Site Admin Joined: 2002-12-10 Posts: 24755 Location: Prague, Czechia Posted: 2013-05-27 Re: type2 (protocol error): "Packet corrupt" [Reply with quote] I did not find anything wrong from WinSCP side in the log. Did you try to google for "OpenSSH Packet corrupt"? I've found couple of references, claiming this to be a network or server problem.

This seems to be for any connection made to the server from any user or IP.

fixed. priority: high: This should be fixed in the next release. http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/portfwd-corrupt.html present-in: 0.53b 2003-06-29 0.54 0.58 We've had several reports of data https://tartarus.org/~simon/putty-snapshots/htmldoc/Chapter10.html corruption in port-forwarded connections. Some (possibly all) of these are due to data loss. The PuTTY client (as opposed to others) appears to be correlated with the data loss, although it's unclear whether the data is actually being lost before or after protocol error PuTTY is dealing with it. Problems have been reported with both directions of tunneling, both directions of data transfer, and both SSH protocols (SSH-1 and SSH-2). Update, 2005-06-15: I (JTN) have reproduced loss of trailing data with a remote-to-local SSH-2 port forwarding, where a burst data is sent from remote to local followed type 2 protocol immediately by EOF. I suspect that PuTTY's lack of support for half-closed connections is to blame in at least this case. Update, 2011-09-13: I (SGT) have just (hopefully) fixed the half-closed issue, so perhaps that will be improved now. The reports below may correspond to several different bugs, as a range of symptoms are reported. 2821c598.0306222343.8ea8a79@posting.google.com (also 3F031766.BC09B85A@uni-mb.si) Server: SSH-1.5-OSU_1.4alpha3 on OpenVMS V7.3-1 Protocol: SSH-1 local-to-remote tunnel of POP3/SMTP Problems with sending messages (dialogue or attachments corrupted) Apparently the first port-forwarded connection in a session will lose some quantity of the data sent from PuTTY to the server from the start of the connection. SSH packet log makes it look like data is being lost by the server (or possibly after PuTTY does the logging), but other clients (e.g., OpenSSH, recent F-Secure) don't show this behaviour. 20040209143157.89534.qmail@web14102.mail.yahoo.com 0.53b + (2004-02-02?) + (2004-02-09?)

We do not attempt to list all error messages here: there are many which should never occur, and some which should be self-explanatory. If you get an error message which is not listed in this chapter and which you don't understand, report it to us as a bug (see appendix B) and we will add documentation for it. 10.1 ‘The server's host key is not cached in the registry' This error message occurs when PuTTY connects to a new SSH server. Every server identifies itself by means of a host key; once PuTTY knows the host key for a server, it will be able to detect if a malicious attacker redirects your connection to another ma
