Post #202,432 by broomberg 4/8/05 8:26:07 AM Reply	Please follow up I try to ask general "is it possible" questions, so as to not waste my time chasing things that can't be done, but not your time either. So I've been reading the smb.conf docs, and I can't figure it out, since the settings that I see (related to permissions and ownership) are all at the share level. So I'm lost at this point.

The nearest I can think of is the INCOMING directory on public FTP servers, which are generally public write-only; you can't read anything in there nor get a directory listing.

Post #202,437 by Another Scott 4/8/05 9:10:40 AM Reply	That was my thought as well. Another option might be to make the drop directory a write-only medium like a write-once CD. I'm not sure how you'd do that though. Cheers, Scott.

On NT, I would even vaguely know how to do it without polling. -- "Consider a perfectly spherical cow, radiating milk isotropically." -- [link\|http://itre.cis.upenn.edu/~myl/languagelog/archives/002008.html\|Language Log]
Post #202,538 by broomberg 4/8/05 6:48:49 PM Reply	Yeah, thought about it I threw up my hands today, said "Screw it, I'm gonna cheat", and write a script that gets kicked off by crontab every 5 minutes to walk the dir tree (there can be many) and chmod / chown as needed. And then, I said, "Screw it all. This is on the bottom of my priority list, why am I wasting oxygen thinking about it?" My PFY was giving me odd looks at that point, and I didn't feel like explaining. So I then buried it.

This came right after we were taught how to write buffer overflows.

Group is write only. so basically like this in the Filesystem: The Directory: /data/share/incoming chmod 6720, chown spooler.writeonlygroup Force samba to write the file as user spooler. Which I believe you already do. And force the create mode as 0620. When the user drops a file there, it basically disappears. Nothing will show up for them at all. You might wanna create a share called incoming. and make it a subdir of /data/share/ The chmod would keep out normal users too. I had a problem with a directory done this way (accidentally) I could see and use it. (mainly because I was an admin user) but nobody else could get in and see what was there. Edit: One last thing, we have to remember Samba follows any restriction the OS puts on it. Even if you want something else in the samba config. Using the OS to create a restricted area itself, but then force a few things to work with the OS restriction underneath Samba, I believe is the way to go. -- [link\|mailto:greg@gregfolkert.net\|greg], [link\|http://www.iwethey.org/ed_curry\|REMEMBER ED CURRY!] @ *i_wethey* [link\|http://it.slashdot.org/comments.pl?sid=134485&cid=11233230\|"Microsoft Security" is an even better oxymoron than "Military Intelligence"] No matter how much Microsoft supporters whine about how Linux and other operating systems have just as many bugs as their operating systems do, the bottom line is that the serious, gut-wrenching problems happen on Windows, not on Linux, not on Mac OS. -- [link\|http://www.eweek.com/article2/0,1759,1622086,00.asp\|source] Edited by folkert April 8, 2005, 12:06:26 PM EDT Expand All History
