What is the format of the vsftpd xferlog file (transfer log)?
It its based on the wuftpd log format.
A typical line might look this this:
Mon Dec 29 15:54:06 2014 1 ::ffff:127.0.0.1 20907184 /myfile.zip b _ i g junk ftp 0 * c
The fields are delimited by spaces. They are:
Number (Sorry don't know what this is)
Mode b = Binary, a = ASCII
Operation _ = no special operation
Direction i = input (eg put), o = output (eg get)
Access mode a = anon, g = guest, r = regular
Service Always ftp
Auth method Always 0
Star Always * "ftp 0 *" is just hardcoded in vsftpd - left over from wuftpd
Completed c = completed, i = incomplete
