[HPADM] Re: FTPD UMASK

Hello:

I have a group to which several users are assigned, the umask for these users is set 00 and the current ftpd umask is set to 027 (default). I know how to change the ftpd umask value, but not sure what it should be changed to in order to produce the following:

User wants all files ftp’ed from remote host to local host user accounts to be u=rw,g=rw permissions

Correct me if I'm wrong. The security and umask settings can best be calculated in ocatal and/or binary format. I always drop down to binary mode for the settings. The wished settings are rw-rw----, in binary (triplets) 110.110.000.

With the umask, you can force the 0-s. Hence to force that, the umask in binarie must be 001.001.111. These triplets transfer to octal as 0117. As far as I know, the umask is in octal so there you have it. Be noted, an octal value is always preceded by a '0', just as a hex value is preceded by '0x'.

I might be off, but the sticky bits and such are also part of this security settings. If you want to force them too, the numbers just get larger: To force no sticky bits, the bin number becomes 011.001.001.111 and the octal 03117. There are more bits but I donnot know them by head. And this larger umask value might be ignored, specially in the ftp-server, because they are ignored at all.
