Secure files on an FTP server
Evening,
What permission do I need to set so that only my FTP logon ID can read / write to a particular folder and subfolders?
It's hosted on a Linux server so I assume it's a CHMOD level but I'm not sure what to set the level to.
I think I just need to check the owner boxes and leave the Group and Public blank...
Anybody confirm this is correct?
Thanks
Lee
Edit: I'm using SmartFTP as the FTP client - CHMOD contains has the Owner column set as User - think that's what confused me!
Edit 2: In the User column - there's a tick box UID - what's that for??

Yep, assuming the FTP username = file owner.

Do I need to set the FTP username as file owner? The files are just about to be uploaded by the FTP owner so I assume it's default?

Re: Secure files on an FTP server
Actually, i'm not sure... I think it depends on the server setup.
I don't think the FTP ACL maps over to the linux ACL so the owner of the file would be the user who executed the FTP daemon.

Re: Secure files on an FTP server
No worries - I've done some testing and I think CHMOD 4700 is the code I need (Owner Read / Write / Execute only)
If anybody else has a thought - please go ahead - In the mean time I'll use that code!
Thanks Gavin!

Re: Secure files on an FTP server
700 would do the job but I don't think there's anything particularly wrong with 4700

Depends on the ftp server.
I know linux servers running cpanel and pure-ftpd as the ftp server map it to the account holders user name.
try chmod 700 (i think) (owner RWX .group --- and public ---)
or Chmod 500 (i think) (owner RW- Group --- and public ---)
Chmod 600 (i think) (owner R-X Group --- public ---)
R= read
W = Write
X = execute
- = No permission.

700 = owner r / w / x
600 = owner r / w
500 = owner r / x
400 = owner r
200 = owner w
100 = owner x

Re: Secure files on an FTP server
Think binary when doing these
Read, Write, Execute
rwx
111 = 7
Read, Write
rw-
110 = 6
Write only
-w-
010 = 2
Read only
r--
100 = 4
etc
So a chmod 701 implies the following
Owner = 7 = 111 = rwx (owner can read write and execute)
Group = 0 = 000 = --- (group has no permissions at all)
World = 1 = 001 = --x (world can execute only)
Yes I'm bored
