Howdy

I keep getting the error 451 then uploading a backup (its about 2.5gb in size)

Command:   STOR downtherabbithole.co.uk.tar.gz
Response:   451 downtherabbithole.co.uk.tar.gz: Append/Restart not permitted, try again
Error:   File transfer failed after transferring 262,144 bytes in 1 second
Status:   Starting upload of D:\Backups\192\27-05-13\downtherabbithole.co.uk.tar.gz
Status:   Retrieving directory listing...

I posted on filezilla's site as I thought it might of been that but an admin told me this

Error codes starting with 4 indicate a temporary error. Just retry at a later time.

Unless of course the server is broken and uses 4 when it should use a 5, in which case you need to contact the server administrator or server hosting provider for assistance to change the error code to the correct one. #

# If you are the admin, you have forbidden resuming in the configuration (in some servers resuming of uploads is disabled by default). Nothing wrong with that administrative decision.

However, the server sends an FTP response code starting with a 4 (451). 4xx means ''Temporary error'', means it will rectify itself if you wait. That's not the case here so the 4xx is plain wrong. Instead, the server must send 5xx, indicating a permanent error (since it won't vanish without your intervention). That's what botg wanted to say.

If the error code cannot be changed in the FTP server configs itself, you should drop a note to the developers so they can fix it.#

Now ive looked in the proftpd.conf but can't find anything

Howdy,

I haven't run into that particular problem before... are you by chance low on disk space? Or maybe that particular account has reached it's quota?

I fixed it in the end Eric by adding

AllowRetrieveRestart on
AllowStoreRestart on
to the config
