FTP error on close, prot violation??? :-(

Didier Morandi_2 — Sat, 25 Jun 2005 13:17:23 GMT

Folks,
Enabling file access failure, I suddenly discover that I have an error message on FTP close:

What did I do wrong? Should I change the ACE? If I should (which is my best guess), why is it badly set up at FTP installation time?

Thanks,

I would say that protection on TCPIP$FTP.DIR is overly permissive. Mine has

TCPIP$FTP.DIR;1 [TCPIP$AUX,TCPIP$FTP] (RWE,RWE,RE,E)

It wants to update file dka0:[TCPIP$FTP]TCPIP$FTP_ANONYMOUS.LOG;1
so that update apparently fails

On my systems I typically get an file access failure audit for attempt to create TCPIP$FTP_SERVER.LOG in the [ANONYMOUS] directory since writing to that is now allowed for ANONYMOUS but otherwise things work

Didier, at a quick glance, it looks like the DTL02$dka0:[tcpip$ftp] directory is owned by system, but is being written by (anony,anonymous) when trying to write a log file when it's finished (but not while accessing...) Also, If you look at it it's asking for control access, when you have only specified read and write...

Didier,

I think changing the ownership of dka0:[000000]TCPIP$FTP.DIR to ANONYMOUS will resolve this issue. And I _think_ I should have been set up like that (then again, since we do not allow anonymous access, I have no comparison for it)

hth,

Proost.

Have one on me.

Most certainly I would expect TCPIP$FTP.DIR to be owned by TCPIP$FTP. not system and most certainly not by ANONYMOUS.

_veli. if unsure, stop FTP service, delete it including TCPIP$FPT.DIR etc and have TCPIP$CONFIG recreate it all the way.

Thanks for your valuable inputs.
I have to travel a bit the three next days (Valbonne, then Utrecht for a VAX to i64 seminar).
I come back to you later.
