#5421 closed Bug report (outdated)

md5sum of files over 2gb changed

Reported by: austin Owned by:
Priority: normal Component: FileZilla Client
Keywords: Cc:
Component version: Operating system type: Windows
Operating system version: windows server 2003


after downloading a file using filezilla (the file was 10gb)and checking the md5sum of the file, the md5sum of the resultant file differed from the md5sum of the original file. whats more the file differed at byte 2147483648, the point the filesize would overflow a signed 32 bit integer. i have re-downloaded the orignal file using ssh on linux (opposed to how it was originally downloaded using filezilla on 32 bit windows server 2003) and the md5sum matches, i transfered it to the windows machine using samba and the md5sum STILL matches, which takes windows out of the equation as the source of the corruption. also being that it occurred AT 2147483648, corruption from download seems unlikely.

sftp to the server and typing "version" gave me this:
SFTP protocol version 3

That's the protocol version, but not the server version.

Please contact the server administrator for further information.

isnt there a way to find out from SSH? i know if i call them they will tell me i will have to get the owner of the account to send in a ticket at which point they can tell him, and he can tell me.

Perhaps. If you set the debug level to 3 in the settings dialog of FileZilla, you should see the version the server advertises when you connect. Unfortunately, a lot of the servers challenged with problems like large file support, often return useless or generic identifiers.

comment:9 by austin, 14 years ago

well if its using sftp, and sshfs(which i used to download the file on my computer) also uses sftp, it doesnt seem to me as though the ftp could be the problem

Do you still have the problem with current FileZilla Client?
