Problems with permissions on files when using ftp

[Ginny Merlino]

Hi,

When I transfer a file using ftp from my c:drive to unix, the file is getting the following permissions rw-r-- ---

the umask for the user that I am transfering to
is 000.

Is there a way to have the file permissions set to 666 when the file is transferred?

Thanks!
Ginny

Hi Ginny:

Yes, you can establish a 'umask' for the ftpd daemon process.

In '/etc/inetd.conf', add '-u 111' to the options for the 'ftpd' daemon. Then, restart 'inetd', thusly:

# /usr/sbin/inetd -c

Hi Ginny,

Yes you can.
You have to use the /etc/ftpd/ftpaccess file to do this.

Here's an example ftpaccess entry:

upload /home/user3 /systools/user3-ftp yes user5 sys 0666

Note how I can also change the default ownership of the file as well.
Also be advised that you have to change the ftp line in /etc/inetd.conf to read like:

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -v -a

The key requirement is the -a parameter - tells inetd to use the ftpaccess file for ftp.

Do a man ftpaccess for further details - especially about the need for a class statement in that file.

HTH,
Jeff

It should be noted that JRF's accurate method would be global to all users. Whereas the method I spelled out can be used to drill down to a specific user & directory.
You could have multiple entries in the ftpaccess file for mult users & even the same user with mult dirs.
Harder to initially setup, but infinitely more flexible.

Thanks for your help!

It worked fine!

Hi (again) Ginny:

Yes, Jeff's choice is certainly the more restrictive and therefore more secure. The default 'umask' for the 'ftpd' daemon in the absence of any '-u ' specifiction is 027. You could tighten or loosen this slightly and then customize as Jeff suggested.
